The TE Connectivity 1717478-1 is an 8-position battery connector receptacle with female blade sockets, built on a 0.098" (2.50 mm) pitch. It is a single-row, through-hole solder part with gold-plated contacts on copper alloy — the gold finish suits repeated mating cycles or mildly corrosive environments like portable device battery bays. The push-pull fastening and keyed housing keep the mate orientation unambiguous, and the black thermoplastic insulation carries a 30 V rating. This is a dedicated battery-style connector, not a general-purpose header: the blade socket contacts are sized for the current draw of a battery pack interconnect.
Single-row means a compact board footprint, one row of eight holes. The 30 V rating is typical for a battery interconnect; the connector is not meant for mains voltage. Gold plating on the contacts matters more for corrosion resistance than for current capacity — if this connector lives inside a sealed device with occasional humidity, the gold prevents fretting corrosion at the mating interface. The keyed housing means the plug only goes in one way, which avoids reversed-polarity damage on a battery circuit.
