Belden Equivalent CCTV Cable: UK Part Numbers 2026

"Belden equivalent" is a specification claim, not a brand promise — it means a cable's conductor gauge, shielding and jacket are built to match a given Belden part number, even though Belden itself never touched the reel. In UK listings, that term is generally used to mean the cable is intended to match the original part number's construction, so always check the seller's own datasheet rather than assuming the part number guarantees it.

For UK buyers substituting into an existing run, that distinction matters more than the name on the box. Get the construction wrong and you'll find out on a fault call, not at checkout.

This guide looks at the Belden part number installers ask for most in the UK CCTV trade — 8723 — against what's actually stocked and sold as an equivalent, and flags where the dossier doesn't yet cover other commonly searched part numbers such as 9540 or 1502R.

Belden Cable Cross-Reference: UK Equivalents by Part Number (8723, 9540, 1502R & More)

Most Belden part numbers people search for — 8723, 9540, 9729, 9501, 1694A, 1502R, 9842 — describe a construction spec (conductor count, shield type, jacket) rather than a proprietary formula, so a UK equivalent only needs to match that construction to do the job. The safest substitution is one that matches shield type and jacket type, not just the part number printed on the drum.

8723 — the one confirmed equivalent

Belden 8723 is a 2-pair individually screened cable, and it's the only part number in this list we can confirm against current UK stock. The equivalent stocked here is the CQR CABTP2X2/GY/LSF100, a Belden Style 8723 match with two individually screened pairs, LSZH sheath and CPR Euroclass Eca rating, sold as a 100m grey reel at £57.27.

CCTV Master also lists its own Belden 8723 Equivalent 2-Pair LSZH Cable, a 100m reel priced at £57.50, built to the same individually-screened construction with an LSZH outer sheath. Both are sold by the reel rather than the metre, so budget for the full 100m when pricing a job. The dossier listing for this product is truncated before it confirms a CPR Euroclass rating, so if you need documented fire-performance compliance for a commercial install, ask CCTV Master to confirm it before you order.

Note that Belden's original 8723 is commonly specified with a standard PVC jacket — it's the equivalents listed above that are built with LSZH sheaths, not an inherent property of "8723" itself.

What does "Belden equivalent" actually guarantee — and what doesn't it cover?

"Belden equivalent" isn't a brand, it's a specification claim — the cable is built to match a Belden part number's construction, typically pair count, shield type and jacket rating, rather than being an original off a genuine Belden production line. It's something you verify against a datasheet, not a warranty you take on trust.

What's actually being matched

A cable sold as a Belden 8723 equivalent should reproduce the core build: 2 individually screened pairs, with the equivalents we stock using an LSZH (Low Smoke Zero Halogen) outer sheath. That LSZH jacket applies to the equivalent products listed here — Belden's original 8723 spec is commonly supplied in PVC, so match jacket type (PVC vs LSZH) to what your job actually needs rather than assuming one follows automatically from the "8723" part number.

The dossier doesn't give a conductor gauge for either the CQR or CCTV Master listings, so treat that as one line item the datasheet should confirm rather than something we can state here — ask the supplier directly before ordering for a commercial build.

The Belden 8723 Equivalent 2-Pair LSZH Cable is sold as a 100m reel at £57.50, built to that same 2-pair, individually-screened, LSZH-jacketed spec. It's the construction match being sold here — not a guarantee that electrical performance is identical across every metre and every batch.

That distinction matters most on longer signal runs or noise-sensitive control wiring. Small differences in screening consistency or conductor purity may, in some installations, show up as attenuation or crosstalk that a datasheet comparison alone won't catch — we haven't bench-tested this ourselves, so treat it as a reason to compare specs carefully rather than a measured result.

Belden CCTV & AV cable cross-reference table (part number → UK equivalent spec)

Only one part number in this list has a dossier-confirmed UK equivalent construction: Belden 8723, built as a 2-pair cable with individually screened pairs. Everything else below is a search term with no verified stock construction behind it, so treat the heading as a starting point for one confirmed cross-reference rather than a full comparison table.

What's actually confirmed: Belden 8723

The Belden 8723 Equivalent 2-Pair LSZH Cable is built to the 8723 spec: two individually screened pairs with a low-smoke-zero-halogen sheath, sold as a 100m reel at £57.50. The CQR CABTP2X2/GY/LSF100 is explicitly badged "Belden Style 8723, 2 Individually Screened Pairs," rated to CPR Euroclass Eca, also on a 100m reel at £57.27.

The Belden 8723 spec calls for two individually screened pairs, and both of these stocked products match that construction. Note that the LSZH sheath is a feature of these particular equivalents rather than something inherent to the "8723" designation itself — the original Belden 8723 is commonly supplied with a standard PVC jacket, so if you're sourcing elsewhere, check the jacket material against your job's requirement rather than assuming LSZH by default. These two are the go-to Belden 8723 equivalents we specify for screened audio, access-control and instrumentation runs where interference rejection matters more than raw bandwidth; the dossier doesn't give conductor gauge for either, so confirm that detail with the supplier before ordering for a job where gauge is critical.

RG59 vs Belden-style twisted-pair cable — which do you actually need?

If your cable needs to carry composite video from an analogue or HD-TVI/AHD camera, you need RG59 coax; if it's carrying telemetry, RS-485 data or audio, you need a Belden-style shielded twisted-pair such as 8723. They solve different jobs, not the same one. Both get sold under the "CCTV cable" umbrella, which is exactly why installers mix them up.

What each cable actually does

RG59's single coaxial core and shield is built to carry a composite video signal at 75 ohms — that's what your analogue camera or HD-TVI/AHD transceiver expects. A Belden 8723 equivalent, like the Belden 8723 Equivalent 2-Pair LSZH Cable at £57.50 for a 100m reel, is two individually screened twisted pairs with an LSZH outer sheath — no coaxial core at all, so it can't carry composite video the way RG59 does.

It's built for balanced signalling instead: pan-tilt-zoom telemetry, RS-485 control loops, door-entry data or line-level audio running alongside a camera.

Don't substitute one for the other

Pushing video down a twisted-pair like 8723, or expecting RG59 to carry an RS-485 control signal cleanly, invites signal loss and interference that a like-for-like swap won't fix in most cases. Match the construction to the signal type, not the label on the drum.

The CQR CABTP2X2/GY/LSF100 is a Belden Style 8723 equivalent with two individually screened pairs and a CPR Euroclass Eca rated LSZH sheath, priced at £57.27 for a 100m reel. It's built for exactly this data/telemetry role, not as a coax substitute.

What actually changes if you substitute an equivalent rather than genuine Belden?

Two specs decide whether a substitute performs like the genuine Belden part: conductor material — bare copper versus tinned copper — and shield construction. Both affect long-run signal integrity and flex life, not necessarily at first fix.

Bare copper can corrode faster where cable meets moisture. Some suppliers specify tinned copper conductors instead of bare copper, on the basis that tinned copper resists oxidation better in damp risers, external ducting and coastal installs. On a bare-copper equivalent left in those conditions, that corrosion may in some cases contribute to resistance changes at terminations over time — potentially showing up as signal degradation well after commissioning, rather than at the point everything first tested fine. Note that the dossier doesn't give conductor gauge for either the CCTV Master or CQR listing, so if that detail matters for your run, ask the supplier directly before ordering.

Shield construction is the second variable, and equivalents aren't consistent here. The Belden 8723 spec calls for two individually screened pairs; the CQR CABTP2X2/GY/LSF100 and CCTV Master's own equivalent both match this construction rather than relying on a single overall foil, which matters for crosstalk on multi-camera runs. Small differences in shield or conductor spec between listings may show up as attenuation or crosstalk in some installations, so treat this as a reason to compare datasheets carefully rather than a guarantee either way — "Belden equivalent" is a specification claim used by UK suppliers to mean the cable is intended to match the Belden part number's construction, not a guarantee that every listing does so, and it says nothing about the jacket material fitted.

**LSZH sheathing is a compliance question, not a nice-to-have — and it's a property of the specific listing, not of "8723" as a spec.
