Obsolete — No Direct Replacement on Record
The 55510-320TR carries an Obsolete lifecycle status. No official successor or pin-compatible replacement is listed by Amphenol ICC (FCI) for this exact order code. For a BOM line that needs this part, the sourcing path is through independent distribution — quantities are confirmed per RFQ, and the available lots are what they are. A board redesign or a functional equivalent from a different series is the alternative.
Surface-Mount Assembly and Pick-and-Place Ready
Termination is solder — surface-mount — and the part is packaged in Tape & Reel (TR) with a Pick and Place feature. That means it feeds into a standard SMT line without manual handling; the vacuum-pick area is defined on the top of the insulation body. The contact material is phosphor bronze, with a tin-lead finish on the solder tail — the gold on the mating face handles the connection, while the tin-lead on the termination side wets well to standard solder pastes during reflow.
