The PTFE dielectric and gold-plated brass center contact keep insertion loss at 0.3 dB across the band, and the through-hole solder termination anchors the shield directly to the board ground plane. No direct replacement or cross-reference is listed on the TE product record. If you are qualifying a new design, look at current SMB jacks in the TE portfolio that share the 50 Ohm, through-hole, snap-on interface; the 221111-1 base number may help locate the right form factor. The 500-cycle mating life is typical for the SMB snap-on interface — the spring-loaded outer shell wears with each cycle, but the gold-on-brass center contact resists fretting through the rated life. The tin-plated brass body and silver housing color are standard for this series; no IP rating is listed, so the connector is intended for dry indoor or sealed-enclosure use where the board-level solder joint provides the environmental seal.","metaTitle":"TE 221111-1 SMB Jack, 50 Ohm, 4 GHz, Through Hole, Obsolete","metaDescription":"TE 221111-1 SMB jack, male pin, 50 Ohm, 4 GHz max, through-hole solder termination, 500 mating cycles.
