Best Alternatives to S4B-EH(LF)(SN)

Package: Through HoleJSTInterconnectsNumber of Positions: 4Pitch: 2.5 mmMounting Type: Through Hole, Right AngleCurrent Rating: 3 AVoltage Rating: 250 V

The JST S4B-EH(LF)(SN) is a 4-pin, 2.5mm pitch, right-angle through-hole header. When seeking alternatives, prioritize matching the right-angle mounting, pitch, and electrical ratings to ensure PCB compatibility.

AI replacement insight

Package riskmedium

PCB footprint and shrouded header dimensions must be verified from mechanical drawings.

Electrical risklow

For candidates with specified ratings, they generally match. Risk is high for parts with missing data.

Can it be replaced directly?

Direct replacement for S4B-EH(LF)(SN) should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

DEALON XH-4PWB offers the closest parametric match but requires datasheet verification for mechanical footprint.

Main risk

Mechanical mismatch is the primary risk. Many similar parts are straight-pin, not right-angle. Pinout and footprint must be identical.
