The 0428203212: The male blade contacts are rectangular and made from copper zirconium alloy, a material chosen for high-cycle durability and resistance to stress relaxation under temperature cycling.
The base product number is 042820; the -3212 suffix specifies the 3-position, right-angle, through-hole, tin-plated variant with board lock. No official second source or pin-compatible replacement is listed from Molex.
Molex 0428203212 is sourced to order against your BOM quantity.
The mating pitch is 10.00mm (0.394 inches). This wide spacing supports higher current per contact and simplifies PCB routing compared to finer-pitch headers.
