1-1623707-1

The 1-1623707-1 from TE Connectivity is a single-row wire-to-board PCB header featuring a standard 2.54mm (0.100 inch) pitch spacing. As part of TE’s extensive connector portfolio, this through-hole header provides a reliable interface between a printed circuit board and external wiring harnesses or cable assemblies. The header features precision-machined pins made from high-conductivity phosphor bronze, plated with nickel as a barrier layer and tin for reliable soldering and corrosion resistance. The insulator housing is molded from high-temperature thermoplastic, capable of withstanding lead-free reflow soldering temperatures while maintaining mechanical rigidity and dielectric properties. The through-hole termination provides excellent mechanical strength and solder joint reliability, making this connector suitable for applications where vibration and mechanical stress may be present. Compatible with standard crimp-terminal housings of the same pitch and pin count, this header enables easy field assembly and servicing. The 1-1623707-1 is commonly used in automotive electronics, industrial control equipment, consumer appliances, telecommunications infrastructure, and general-purpose board-to-wire interconnection applications where dependable signal and power transmission is essential.

The 1-1623707-1 PCB header operates as the board-side male component of a wire-to-board connector system. Each contact pin extends through the PCB and is soldered to a plated through-hole, providing both electrical connection and mechanical anchoring. The exposed portion of the pin above the board serves as the male mating interface, designed to mate with female crimp terminals inside a compatible connector housing. When the mating housing is inserted onto the header, the female contacts (typically spring-loaded or formed phosphor bronze receptacles) make intimate contact with the square or round header pins, establishing a reliable electrical path between the wire harness and the PCB. The tin plating on both header and contact surfaces provides low contact resistance and good corrosion resistance. The 2.54mm pitch spacing is an industry standard that balances contact density with manufacturability and creepage/clearance distances, making it suitable for signal and low-to-medium power applications. The thermoplastic housing provides insulation between adjacent contacts and locates the pins in precise alignment to ensure proper mating with the corresponding receptacle connector. The through-hole mounting distributes mechanical stress across the PCB, providing robust resistance to pull-out forces and vibration.

Note: The 1-1623707-1 is a 2.54mm pitch single-row vertical through-hole header. The exact number of positions and overall dimensions should be verified against the TE Connectivity official drawing for the specific application. Mating requires the corresponding TE connector housing with compatible pin count and pitch.
