1.27mm Pitch, 30-Position SMT Receptacle for Board-to-Board Stacking
The 20021321-00030T4LF: This is a 30-position, dual-row receptacle from the Minitek127® series, built for board-to-board interconnects where the 1.27mm pitch keeps routing dense and the z-height low. The surface-mount tails reflow onto the board pads, and the 0.177" (4.50mm) insulation height sets the mated stack height against a matching pin header. Push-pull latching means the connector seats without a locking ramp — it's a friction-retained mate suited for applications where the board pair stays assembled through the product life and the risk of vibration-induced disconnect is low. For environments with shock or constant vibration, a header with a locking latch would be a better fit.
Mating Compatibility with Standard 1.27mm Pin Headers
The female socket contacts are designed for headers with a 0.64mm square pin — typical for the Minitek127 series and other 1.27mm pitch families. Confirm the header's pin length and stack height against the 4.50mm insulation height of this receptacle before committing the board stack.
