Product details

It carries a 0.156" (3.96mm) mating pitch — the classic KK spacing that gives enough room for 600V rated creepage without demanding a dense board layout.

Fit and Termination

Right-angle through-hole mounting with a 0.145" (3.68mm) solder post — the board footprint is a straight match for the 0.156" pitch grid. Board hooks on the housing body grab the PCB during wave solder and provide shear resistance against cable strain.

Sourcing Reality — Obsolete Status

No official successor order code is listed on record. For a BOM line that needs this exact 4-position KK396 receptacle, the supply channel is independent distribution — surplus, NOS (new old stock), or broker inventory with traceable date codes. If a pin-compatible alternative is acceptable, the broader KK396 family includes active 4-position receptacles at the same 0.156" pitch — confirm the locking ramp and board hook feature match before substituting.

Construction Notes

Housing is white polyamide (nylon) with a UL94 V-2 flammability rating.
