Is there a pin-compatible replacement for KH-HX2.54-03Z?

Yes, several candidates like ZX-XH2.54-3PZZ-R and WAFER-XH254Z-3AM appear to be pin-compatible in form and fit. However, they are not identical due to differences in contact material (Tin vs. Gold), which must be verified for your application.

What risks should I check before replacing KH-HX2.54-03Z?

The primary risk is the contact plating downgrade from Gold to Tin, which can impact performance in corrosive environments or low-signal applications. Always verify the candidate's mechanical dimensions against your PCB layout using its datasheet.

KH-HX2.54-03Z Alternatives, Datasheet & Cross Reference | Guangdong Hongzhi Electronics Technology Co., Ltd.

KH-HX2.54-03Z is a 3-pin, 2.54mm pitch header with Gold-plated contacts. While several alternatives match its form factor and electrical ratings, they typically feature Tin plating, requiring careful evaluation for your specific application.

AI replacement insight

Package risklow

Candidates match the through-hole, 2.54mm pitch form factor.

Electrical riskmedium

Contact plating downgrade from Gold to Tin requires application-specific review.

Can it be replaced directly?

No direct drop-in replacement with identical specifications has been identified; all viable alternatives have Tin-plated contacts instead of the target's Gold plating.

Best replacement path

Use a candidate with a 3A current rating like ZX-XH2.54-3PZZ-R, but verify the impact of Tin vs. Gold contact plating for the application.

Main risk

Contact plating downgrade from Gold to Tin, which can affect long-term reliability and contact resistance.

Recommended alternatives

A form-fit compatible 3-pin header with a 3A current rating, but features Tin plating instead of Gold.
