80-position mezzanine receptacle on 1.27mm pitch
The 20021321-00080T4LF: The 1.27mm mating pitch and 1.27mm row spacing set a compact footprint that routes two signals between the rows on a standard PCB. The surface-mount termination (SMT) allows reflow soldering in a pick-and-place line. The tin-plated solder tails (100µin) are compatible with standard SAC305 reflow profiles.
Position count and peer comparison
For a BOM that needs fewer I/O, the 60-position sibling is a drop-in alternative on the same footprint pitch, but the board layout must account for the shorter body. No other spec — contact plating, insulation height, or material — changes across the range.
Sourced through independent distribution channels. The base product number 20021321 covers the full Minitek127 SMT receptacle family, so a BOM line for the 80-position variant is a distinct order code.
The 1.27mm pitch and 1.27mm row spacing demand a matching 80-position, dual-row, 1.27mm-pitch pin header from the Minitek127 series. The push-pull retention means the header must have a smooth pin surface for the socket beam to wipe and grip. Applications listed include general purpose, industrial, and telecommunications.
