DF36-30P-0.4SD(51) from Hirose Electric Co Ltd is a fine-pitch 30-position plug housing designed for compact wire-to-board interconnect applications where space, signal density, and secure cable retention matter. With a 0.40 mm pitch, free-hanging in-line mounting style, solder cable termination, and support for discrete 42-46 AWG wire, it is well suited for miniaturized consumer, portable, medical, and industrial electronic assemblies. Engineers typically choose this DF36 series connector for high-density internal cable routing, especially in designs that require latch-based fastening and gold-finished contacts for reliable connectivity. Lifecycle status is currently listed as unknown, so teams planning long-term production should confirm active supply status directly with Hirose or an authorized channel before locking it into new designs. RoHS compliance information is not provided in the supplied specifications, so compliance should be treated as information not available until verified through official manufacturer documentation or current distributor compliance records.
