32-Pin, Dual-Row Unshrouded Header for Board-to-Board Stacking
The 57202-G52-16LF is a 32-position, dual-row unshrouded header from the Minitek® 2.00mm series, designed for board-to-board interconnects where a low-profile, solderless press-fit is not required — termination is SMT solder to the PCB.
The post (solder tail) finish is tin at 78.7 µinch (2.00 µm), which wets well during reflow but does not match the corrosion resistance of the gold mating surface — the tin tail is the board-side interface, not the contact interface.
SMT Termination and Board-Level Fit
In vibration-prone environments, a secondary mechanical anchor (board lock or adhesive) should be evaluated. The contact mating length is 0.157" (4.00 mm), which sets the minimum mated stack height when paired with a receptacle — confirm the receptacle's mating depth to avoid bottoming out.
The base product number 57202 covers the series; the -G52-16LF suffix specifies the 32-position, gold GXT™, SMT variant. Sourced through independent distribution against the BOM quantity.
