The through-hole termination and 2.29 mm post length provide a stable solder joint on standard 1.6 mm PCBs.
Tin contacts are rated for fewer mating cycles than gold — typically 50 to 100 cycles — and are best suited to environments free of corrosive gases or frequent reconnection. For applications requiring higher mating cycle life or resistance to fretting corrosion, a gold-plated variant from the same series would be specified. This part's tin finish aligns with cost-sensitive, one-time or infrequent-mate builds.
