Is there a pin-compatible replacement for B2P-VH-R(LF)(SN)?

Yes, parts like ZX-VH3.96-2PLT and KH-VH-2P-Z share the same 2-pin, 3.96mm vertical through-hole footprint. However, you must verify the lower current rating is acceptable for your design.

What risks should I check before replacing B2P-VH-R(LF)(SN)?

The primary risk is the lower current rating of most alternatives (typically 7A vs the original 10A). This could cause overheating or failure in high-power applications. Always verify the substitute's datasheet.

B2P-VH-R(LF)(SN) Alternatives, Datasheet & Cross Reference | JST

AI replacement insight

Electrical riskmedium

Substitutes have a 7A rating vs. target's 10A. Risk of overheating in high-power designs.

Package risklow

Candidates with vertical mounting are good form-fit matches.

Can it be replaced directly?

No direct drop-in replacement with a 10A rating was found. Alternatives like ZX-VH3.96-2PLT are form-fit compatible but have a lower 7A current rating.

Best replacement path

Use a cross-vendor vertical 3.96mm header, but verify the current rating is sufficient for the application.

Main risk

Electrical overstress due to lower current rating on substitutes.

Recommended alternatives

A 2-pin, 3.96mm vertical header with a lower current rating of 7A. Verify suitability for your application.
