Is there a pin-compatible replacement for WAFER-ZH1.5-2PLB?

No pin-compatible replacement with matching electrical ratings has been confirmed. JST's B2B-ZR(LF)(SN) has a compatible form factor but a lower voltage rating and requires footprint verification.

What risks should I check before replacing WAFER-ZH1.5-2PLB?

The main risks are electrical and mechanical. Verify the candidate's voltage rating (most are 50V vs. the original's 250V) is sufficient for your circuit. Also, compare datasheet drawings to ensure the PCB footprint is identical.

WAFER-ZH1.5-2PLB Alternatives, Datasheet & Cross Reference | XUNPU

WAFER-ZH1.5-2PLB is a 2-pin, 1.5mm pitch vertical through-hole header from XUNPU. Finding a replacement requires matching the vertical orientation, pitch, and 250V rating.

AI replacement insight

Electrical riskhigh

Voltage rating of alternatives is 50V, a major downgrade from the target's 250V.

Package riskmedium

PCB footprint must be verified from datasheets to ensure mechanical compatibility.

Can it be replaced directly?

No direct, fully-rated drop-in replacement has been identified. All potential alternatives with a matching vertical form factor have a lower voltage rating.

Best replacement path

Consider JST's B2B-ZR(LF)(SN) if a lower voltage rating of 50V is acceptable for your application. Footprint verification is mandatory.

Main risk

The primary risk is the significantly lower voltage rating (50V vs 250V) of available vertical-mount alternatives.

Recommended alternatives

JST vertical header with same pitch and pin count, but a lower voltage rating of 50V.
