A single-wall shroud surrounds the 0.295" (7.49mm) long square male pins, providing basic polarization during mating. The tin-plated solder tails (150 µinch) are designed for wave-solder through-hole assembly. Rated for 250VAC and a current that varies by wire gauge, the header suits general-purpose power and signal distribution inside equipment enclosures.
This header mates with MTA-100 receptacle housings (e.g., 640441 series) and IDC connectors that accept 18-26 AWG discrete wire or ribbon cable. Through-hole termination: the 0.140" (3.56mm) post length suits standard 1.6mm PCBs.
Comparing the 641215-3 to its peer alternatives
The 641215-3 differs in three decision-relevant axes: 3 positions vs 4, single-row vs dual-row, and gold vs tin on the mating surface. For a 3-circuit single-row board-to-cable application with gold contacts, the 641215-3 is the direct choice — the 1-1871673-2 is a different footprint and contact system.
