Is there a pin-compatible replacement for WAFER-XH254JK-2A?

Yes, several candidates like WF-1B254A2P and A2541WR-2P are functionally pin-compatible (2-pin, 2.54mm pitch, right-angle). However, you must verify the mechanical drawings in the datasheets to confirm an exact PCB footprint match before ordering.

What risks should I check before replacing WAFER-XH254JK-2A?

Before replacing, check three main things: 1) Mechanical Fit: Confirm the PCB footprint and pin dimensions from the datasheet. 2) Mounting Type: Ensure the replacement is also a right-angle header. 3) Material Properties: Check for any differences in housing material or flammability ratings (e.g., UL94V-0).

AI replacement insight

Electrical risklow

Several candidates match the 3A/250V rating.

Package riskmedium

While mounting type matches on good candidates, subtle footprint differences are common and must be checked.

Sourcing risklow

This is a common connector type with multiple manufacturers.

Can it be replaced directly?

There are several strong functional alternatives, but a direct pin-for-pin replacement requires comparing the datasheet's mechanical drawings to ensure the footprint and pin lengths are identical.

Best replacement path

WF-1B254A2P by BXCONN or A2541WR-2P by CJT are strong candidates after verifying mechanical drawings for an exact footprint match.

Main risk

The primary risk is a mismatch in mechanical dimensions (footprint, pin length, housing size) or material properties like flammability rating.

Recommended alternatives

A strong alternative with matching pitch, pin count, right-angle mounting, and key electrical ratings.
