SMB Jack, Dual-Mount Flexibility
The 0734041890: The connector accepts both Surface Mount and Through Hole mounting — a dual-termination footprint that lets you reflow the shield and hand-solder the centre contact, or vice versa, depending on your board assembly line. Both the shield and the contact terminate via solder, so no crimp tooling is needed for the RF path. The bulk packaging suits bench builds and prototype runs where tape-and-reel feed isn't required.
Active lifecycle — no end-of-life notice on record, so this part is still in normal production. No official cross-reference or second-source listed, so stick with the 73404 series for a guaranteed fit.
