Board-to-Board Receptacle for Tight Stack-Up
The 20021321-00008T4LF is an 8-position, dual-row receptacle from the Minitek127® 1.27mm series by Amphenol ICC (FCI). It is a board-to-board connector with a 1.27 mm pitch and a 1.27 mm row spacing, designed for surface-mount soldering on a PCB. In a low-vibration bench or telecom card environment, this is sufficient; for automotive or machine-tool duty, consider a header with a locking ramp. This is a mid-cycle plating grade — suitable for occasional mating in field-service or test fixtures, but not rated for the 500-cycle durability of 30-µin gold.
At 1.27 mm pitch and 1.27 mm row spacing, the 8-position dual-row layout occupies a 4.06 mm × 1.27 mm footprint on the PCB — tight enough for dense signal routing, but still hand-solderable under a microscope. Compared to a 10-position sibling in the same series, this 8-position variant saves two board traces and reduces the connector footprint by 2.54 mm in length — a meaningful difference when routing traces between two tight rows of vias.
RoHS compliant per the listing. No official pin-compatible cross-reference or successor is listed from the original manufacturer.
