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

Yes, several parts like JST S2B-ZR(LF)(SN) are pin-compatible in terms of pitch, pin count, and right-angle mounting. However, they are not electrically equivalent, featuring much lower voltage ratings.

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

The primary risk is electrical overstress. The target is rated for 250V, while all mechanically similar alternatives are rated for 50V or 100V. Using them in a high-voltage application can lead to failure.

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

WAFER-ZH1.5-2PWB is a 2-pin, 1.5mm pitch right-angle header from XUNPU, rated for 1A and 250V. Finding a direct replacement requires careful review of electrical ratings as alternatives have lower voltage specs.

AI replacement insight

Electrical riskhigh

All candidates have much lower voltage ratings (50-100V vs 250V).

Package risklow

Several candidates match the 1.5mm pitch, 2-pin, right-angle through-hole package.

Can it be replaced directly?

No direct, drop-in replacement for WAFER-ZH1.5-2PWB was found. All form-fit compatible candidates have significantly lower voltage ratings.

Best replacement path

Verify if the application's actual voltage is below 100V. If so, HC-ZH1.5-2AW is a potential form-fit match. If below 50V, JST's S2B-ZR series is an option. Otherwise, no direct substitute was found.

Main risk

Electrical overstress due to lower voltage ratings on all potential alternatives.

Recommended alternatives

Matches form and fit but has a much lower voltage rating (50V). Requires engineering review.

Questions & answers

There is no single best alternative. Candidates like JST's S2B-ZR(LF)(SN) and HCTL's HC-ZH1.5-2AW match the form and fit but have lower voltage ratings (50V-100V vs 250V). Selection depends on your circuit's actual voltage.
