The 20021321-00010C4LF is a MINITEK127R surface-mount receptacle connector designed for vertical termination (VT) applications. This connector features a 1.27 mm pitch with configurable pin counts ranging from 2×3 to 2×50 positions, accommodating various circuit board layouts. The housing is constructed from high-temperature plastic (UL94-V0) in black, with phosphor bronze terminals and optional stainless steel cap. The connector supports multiple plating options including gold flash, GXT, and matte tin finishes on both contact and solder tail areas, with nickel underplating. It is rated to withstand 260°C peak temperature for 10 seconds in convection, infrared, or vapor phase reflow ovens, making it suitable for modern surface-mount assembly processes. This connector is ideal for compact electronic devices requiring reliable interconnection in space-constrained applications.
