Product details

The S03B-XASK-1(LF)(SN): It mates with JST XA series crimp receptacles (sold separately) to form a locking wire-to-board connection. The through-hole press-fit tails align the part before soldering, simplifying assembly.

At 2.50 mm pitch, this header occupies a compact board footprint — the 3 positions fit in a row width determined by the pitch and position count. Insulation height of 0.299 inch (7.60 mm) provides clearance for mating receptacle housing.

Environmental and Safety Ratings

The base product number is S03B-XAS; the full order code S03B-XASK-1(LF)(SN) includes the (LF)(SN) suffix for lead-free and tin-plate finish.
