In a harness that sees quarterly reconnects, that plating alone buys decades of reliable contact at the interface. Insulation is UL94 V-0 rated thermoplastic, natural colour.
Right-Angle Routing and Board Footprint
The right-angle orientation sets the connector body 0.225" (5.72 mm) above the PCB surface, with the mating pin length at 0.295" (7.49 mm) and the solder tail at 0.140" (3.56 mm). The 0.100" pitch drives the board footprint: each pin sits on a 2.54 mm grid, which keeps routing density moderate and allows two-layer boards to break out all 12 traces without a via.
Mating and Wire-Gauge Compatibility
The voltage rating is 250 VAC — suitable for signal and low-power distribution in control panels, test equipment, and appliance wiring.
The base product number is 641214; the full 4-641214-2 order code includes the plating and packaging variant (bulk). No pin-compatible alternative is listed from TE — if a second source is needed, the pitch, circuit count, and right-angle orientation are the matching criteria.
