302-012-256-201

Edgeboard Connectors Overview

The EDAC Inc. 302-012-256-201 is a dual-edge card edge connector from the 302 series, designed for board edge mounting with a 0.050" (1.27mm) contact spacing. It features 12 positions in a female configuration with gold-plated cantilever contacts. The housing is constructed from black polyamide (PA66), supporting card thicknesses between 0.051" and 0.071" (1.30mm to 1.80mm). Rated for -55°C to 85°C, it utilizes a solder termination method and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design with cantilever spring contacts for reliable mating
• Gold flash plating on copper alloy contacts ensures corrosion resistance and low contact impedance
• Black polyamide insulation provides structural stability and thermal endurance within specified operating ranges

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Medical device circuit board interfaces
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 12-position dual-edge specification before ordering. Confirm that the target PCB card thickness falls within the 1.30mm to 1.80mm range to ensure proper mechanical engagement. Check for RoHS3 compliance requirements if applicable to the end product. Ensure the supplier source is authorized to guarantee component authenticity and traceability.

Edgeboard Connectors Selection Notes

Select this connector when a 1.27mm pitch dual-edge interface is required for compact board-to-board connections. The female gender and cantilever contact type are suitable for applications requiring easy insertion and removal of daughter cards. Consider the black PA66 housing for environments where standard color coding or specific thermal ratings are necessary. Verify that the solder termination method aligns with the assembly process capabilities.

Edgeboard Connectors Part Context

This component belongs to the EDAC 302 series of standard card edge connectors. The series offers various position counts and contact configurations to accommodate different circuit density needs. The 302-012-256-201 specifically addresses the need for a 12-position dual-edge solution with precise 0.050-inch spacing, fitting into the broader portfolio of EDAC interconnect solutions.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 302 series parts with identical pin counts and spacing, such as 302-012-256-206, if housing color variations are acceptable. Cross-brand replacements require matching the 1.27mm pitch, dual-edge female configuration, and compatible card thickness range to maintain mechanical and electrical integrity.
