Pin Dimensions for Board Fit
The 350491-1: Overall length is 0.405" (10.29 mm), with 0.245" (6.22 mm) standing above the flange — that's the post height available for a mating receptacle or wire wrap. The pin diameter above the flange is 0.093" (2.36 mm), and the flange itself measures 0.115" (2.92 mm) across. Designed for a 0.062" (1.57 mm) thick board. The mounting hole diameter should fall between 0.067" and 0.073" (1.70 mm to 1.85 mm) — the clinch-fit legs expand into that range for a press-in hold before soldering.
Terminal Construction and Finish
Single-post terminal with a flanged base — the flange seats against the board surface and prevents the post from pushing through during clinching or soldering. Termination is clinch fit, meaning the post is pressed into the plated through-hole and the barrel is swaged on the opposite side. Contact material is phosphor bronze, a spring-grade alloy that resists fatigue under repeated insertion and extraction. The contact finish is tin — good for solderability and cost-effective for moderate-cycling applications where gold isn't required.
