The 5050864-6: This part is RoHS compliant, meeting the directive requirements for lead-free assembly. Bulk packaging is standard, so plan for tube or tray handling on the line rather than reel feed.
What This Pin Socket Accepts and How It Mounts
The socket accepts a mating pin diameter of 0.026" to 0.033" (0.66 mm to 0.84 mm), covering standard 0.025" square header pins and round pins within that range. The closed-bottom design prevents solder wicking into the contact area during wave soldering. Socket depth is 0.244" (6.20 mm), which sets the insertion depth for the mating pin and the overall z-height budget on the board. The no-tail design means the socket sits flush with the board surface after soldering, keeping the profile low. Termination is solder-only — the socket is inserted into a mounting hole diameter of 0.062"~0.063" (1.57 mm~1.60 mm) and soldered in place. No press-fit or compliant-pin option is offered.
Contact Material and Plating — Why They Matter
The contact is beryllium copper, chosen for its high yield strength and spring memory — it maintains contact force over repeated insertions without taking a set. Overall length is 0.257" (6.53 mm) and flange diameter is 0.080" (2.03 mm), confirming the socket's compact footprint.
