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

No direct pin-compatible replacement has been identified in this review. Alternatives like S08B-PASK-2(LF)(SN) are right-angle, requiring a different PCB footprint. Other straight connectors have different mating interfaces.

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

Key risks include: 1) Mechanical fit, especially mounting orientation (straight vs. right-angle) and PCB footprint. 2) Mating compatibility, as different connector series will not mate. 3) Electrical ratings, ensuring the replacement's voltage and current are sufficient.

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

The JST B08B-PASK(LF)(SN) is an 8-pin, 2.0mm pitch, straight through-hole header. Finding a direct pin-compatible replacement is challenging, but functional alternatives exist if PCB layout or electrical parameters can be adjusted.

AI replacement insight

Package riskhigh

Most alternatives have different mounting (right-angle) or row count, requiring PCB redesign.

Electrical riskmedium

Some candidates have lower voltage or current ratings that must be verified for the application.

Can it be replaced directly?

No direct, drop-in replacement was found. All viable alternatives require design review for mechanical or electrical differences.

Best replacement path

Use S08B-PASK-2(LF)(SN) if a right-angle orientation and 100V rating are acceptable, as it maintains mating compatibility.

Main risk

The primary risk is mechanical incompatibility, due to different mounting orientation (right-angle vs. straight) or a different shroud design preventing proper mating.

Recommended alternatives

Same connector family but right-angle mount and lower voltage rating; requires layout change.
