Is there a pin-compatible replacement for 2.54-6PWTDK?

S6B-XH-SM4-TB(LF)(SN) and ZX-XH2.54-6PWT are strong candidates for pin-compatibility, as they match the form and function. However, they are not officially cross-referenced, so you must compare the datasheet drawings to your PCB layout to confirm a perfect fit.

What risks should I check before replacing 2.54-6PWTDK?

The main risk is mechanical incompatibility. Always verify the PCB footprint (solder pad dimensions and positions) from the candidate's datasheet. Also, check for minor differences in housing material temperature ratings and contact pin material (e.g., Brass vs. Phosphor Bronze) which could affect performance in demanding environments.

2.54-6PWTDK Alternatives, Datasheet & Cross Reference | SHOU HAN

Finding a substitute for the 2.54-6PWTDK, a 6-pin 2.5mm pitch SMT header, involves matching the mounting type and verifying the PCB footprint. Several strong functional alternatives exist from manufacturers like JST and Megastar.

AI replacement insight

Package riskmedium

SMT footprint dimensions for XH-style connectors can vary slightly between manufacturers. Verification is required.

Electrical risklow

Top candidates match the 3A/250V rating. Minor material differences are unlikely to impact most applications.

Can it be replaced directly?

No guaranteed drop-in replacement is confirmed. S6B-XH-SM4-TB(LF)(SN) and ZX-XH2.54-6PWT are strong SMT candidates that require PCB footprint verification against their datasheets before procurement.

Best replacement path

S6B-XH-SM4-TB(LF)(SN) by JST is the strongest candidate, as it's an SMT part from the original XH series designer. However, PCB footprint verification is mandatory.

Main risk

The primary risk is a mismatch in the PCB solder pad layout (footprint), which would prevent assembly.

Recommended alternatives

A 6-pin, 2.5mm pitch SMT right-angle header from JST with matching electrical ratings.
