Is there a pin-compatible replacement for B08B-XASK-1(LF)(SN)?

No pin-compatible replacement has been verified. Several parts have similar electrical specs but fail on mechanical compatibility, such as orientation, pitch, or connector family housing design.

What risks should I check before replacing B08B-XASK-1(LF)(SN)?

Key risks are mechanical. Verify the pitch (2.50mm), pin orientation (straight), and shroud dimensions. Ensure the replacement is compatible with the JST XA series mating connector, as other series like XH are not inter-mateable.

B08B-XASK-1(LF)(SN) Alternatives, Datasheet & Cross Reference | JST

Finding a substitute for the JST B08B-XASK-1(LF)(SN) requires matching its 8-pin, 2.50mm pitch, straight orientation, and XA-series housing. Careful verification of mechanical drawings is essential for compatibility.

AI replacement insight

Package riskhigh

Candidates have wrong orientation, pitch, or incompatible connector series (XA vs XH).

Electrical risklow

Most candidates match the 3A/250V electrical ratings.

Sourcing riskmedium

Finding a true XA-series compatible part from another vendor may require careful datasheet review.

Can it be replaced directly?

No direct drop-in replacement was found. All reviewed candidates have critical mechanical differences requiring design changes.

Best replacement path

Search for manufacturers producing direct clones of the JST XA series, ensuring pitch, pin count, and orientation match.

Main risk

The primary risk is mechanical incompatibility due to connector housing design (series), which prevents proper mating.

Recommended alternatives

A functional alternative with a matching PCB footprint, but requires using a compatible XH-series mating connector.
