A JST XH series variant with identical electrical specs but may lack the PCB mounting boss.
S5B-XH-A-1(LF)(SN) is a 5-pin, 2.5mm pitch right-angle header from JST's popular XH series, commonly used for wire-to-board connections in a wide range of electronics. Finding a suitable replacement requires careful attention to mechanical details.
Many similar MPNs are straight instead of right-angle. Footprint may differ (e.g. mounting boss).
Key electrical ratings (3A, 250V) are standard for this connector type and easily matched.
Multiple vendors make XH-style connectors, but dimensional consistency is not guaranteed.
A direct drop-in replacement is not confirmed, but S5B-XH-A(LF)(SN) from JST is the closest option. Users must verify their PCB layout can accommodate a part without a mounting boss.
The best alternative is S5B-XH-A(LF)(SN), a variant from the same JST XH series that likely only differs by not having a PCB mounting boss.
The main risk is mechanical incompatibility. Several candidates have the wrong (straight) orientation, and even the best options require verifying the PCB footprint and housing dimensions.

The best alternative is S5B-XH-A(LF)(SN) from JST, which is electrically identical but may lack the PCB mounting boss. For a cross-vendor option, XH-5PWB from DEALON is a strong candidate but requires datasheet verification.
