The 20021121-00052D1LF is the 52-circuit member of the Amphenol Minitek127® 1.27mm header line, a dual-row unshrouded board-to-board header.
At 52 positions this header occupies the high-end of the Minitek127® 1.27mm range — the 1.27 mm pitch and 0.050" row spacing are shared across the series, so the board footprint scales linearly with position count.
No same-series pin-compatible alternative is listed — the 52-position count is unique in the series at this pitch. Confirm the circuit count before ordering.
