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.","metaTitle":"Molex 0009521041 KK396 Receptacle, 4 Position, 3.96mm Pitch","metaDescription":"Molex 0009521041 KK396 2145 series receptacle, 4 circuits, 0.156\" pitch, 4.5A, 600V, tin contacts, locking ramp.
