Is there a pin-compatible replacement for A1501WV-S-4P?

Yes, parts like JST's B4B-ZR-SM4-TFT(LF)(SN) and HCTL's HC-ZH-4PLT appear to be pin-compatible. However, they are not drop-in replacements due to a lower voltage rating. You must verify the datasheet for the exact footprint and confirm the electrical specifications.

What risks should I check before replacing A1501WV-S-4P?

The primary risk is electrical. Most alternatives are rated for 50V, while the A1501WV-S-4P is rated for 100V. Using a lower-rated part can lead to failure. Always verify the mechanical footprint from the datasheet to ensure it matches your PCB layout.

A1501WV-S-4P Alternatives, Datasheet & Cross Reference | CJT

Reviewing alternatives for the CJT A1501WV-S-4P, a 4-pin 1.5mm vertical SMT header. Key factors for replacement are matching the vertical orientation and ensuring the alternative's voltage rating meets or exceeds the original's 100V specification.

AI replacement insight

Electrical riskmedium

All identified alternatives have a 50V rating, half of the target's 100V. This is a critical check.

Package risklow

The 1.5mm pitch vertical SMT header is a standard form factor, but footprint verification is always recommended.

Sourcing risklow

The JST ZH series and its compatibles are widely available from multiple manufacturers.

Can it be replaced directly?

No direct drop-in replacement is confirmed. Alternatives from JST and HCTL exist but have a lower voltage rating, requiring engineering review before use.

Best replacement path

Cross-reference to JST's ZH series, like B4B-ZR-SM4-TFT(LF)(SN), which offers similar form but requires checking the lower voltage rating (50V vs. 100V).

Main risk

Electrical stress due to the lower 50V voltage rating on all viable alternatives compared to the target's 100V rating.

Recommended alternatives

A form-fit compatible header from JST's ZH series, but with a lower voltage rating.
