302-050-256-201

Edgeboard Connectors Overview

The EDAC Inc. 302-050-256-201 is a standard card edge connector from the 302 series, designed for dual-edge board applications. It features 50 positions with a 0.050 inch (1.27mm) contact spacing. The connector utilizes female contacts with gold flash plating to ensure reliable signal transmission. Constructed with a black polyamide (PA66) housing and copper alloy terminals, it supports surface mount or through-hole termination depending on specific variant configurations within the series.

Edgeboard Connectors Feature Summary

• Dual-row configuration for high-density interconnects
• Gold flash plated contacts for corrosion resistance
• Black polyamide insulation for thermal stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust connectivity
• Medical equipment interface modules
• Telecommunications hardware backplanes

Edgeboard Connectors Procurement Notes

Verify the exact termination style and mounting orientation against the official datasheet before ordering, as the 302 series includes variations in lead form and panel cutout requirements. Confirm that the gold flash thickness meets the specific cycle life requirements of the target application environment. Ensure compatibility with the PCB trace width corresponding to the 1.27mm pitch.

Edgeboard Connectors Selection Notes

Select this component when a 50-position dual-edge connector is required with a 1.27mm pitch. Consider the operating temperature range of -55°C to 85°C for environmental suitability. Evaluate the mechanical retention needs against the housing design without integrated mounting lugs. Compare against other series if different contact spacing or board thickness tolerances are necessary for the system architecture.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 series, which specializes in standard card edge connectors. The series offers various position counts ranging from low to high density, all maintaining consistent 0.050-inch spacing. The 302-050-256-201 represents a mid-to-high position count option within this standardized family, focusing on reliability and compact footprint for dual-sided circuit boards.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 302 series variants with matching pin counts and pitch, such as the 302-048-256-201 or 302-052-256-201 if available. Cross-brand replacements require verifying identical dimensional profiles, contact material specifications, and insulation resistance values to ensure functional interchangeability.
