It is a board-to-cable/wire power interconnect with a 10.16mm pitch, designed for applications where high current and robust mechanical retention are required — think industrial power distribution, servo drives, and general-purpose equipment that needs a locked, polarized connection. The 30A per circuit rating means each contact carries bus-level current, not signal-level; the 630V voltage rating supports high-voltage DC rails or AC line inputs.
The 10.16mm pitch is the first fit check — it determines the board footprint and the minimum spacing between adjacent connectors. At this pitch, the header occupies a wide footprint on the PCB, which is expected for a power interconnect rated 30A per circuit. The through-hole termination provides stronger mechanical retention than SMT for a connector that will see cable strain. The tin solder tail is standard for wave or hand soldering; no special process required. The IP20 rating means it is not sealed against moisture — keep it inside an enclosure.
It is RoHS compliant. For BOM commitment, the risk is low: the part is in current manufacture, and the Dynamic D-5200 series has broad distribution coverage. No official cross-reference or second-source is on record, so the BOM line should be specified against the TE order code directly.
