305-038-521-203

Edgeboard Connectors Overview

The EDAC Inc. model 305-038-521-203 is a standard card edge connector header featuring 38 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The connector employs female half-bean spring contacts with gold plating over a copper alloy base, rated for 5 A current. Designed for panel mounting via solder pins, it operates within a temperature range of -40°C to +105°C and features a green thermoplastic insulator body.

Edgeboard Connectors Feature Summary

• Dual-row female configuration with half-beam spring contacts for secure board retention
• Panel mount installation style with vertical orientation and solder pin termination
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Thermoplastic insulator body provides structural integrity across specified operating temperatures

Edgeboard Connectors Applications

• Industrial control system backplanes requiring robust dual-edge connections
• Telecommunications equipment interface modules
• Test and measurement instrument internal signal routing
• Automotive electronic control unit interconnects

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm contact spacing, row count, and flange characteristics. Ensure the target application supports the required 1.57 mm PCB thickness and panel mounting constraints. Cross-reference the RoHS compliance status with current regulatory requirements for the destination market before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density 38-position interface is required with a wide 3.96 mm pitch. The dual-row layout maximizes connection density while maintaining adequate spacing. Verify that the mating card edge thickness falls within the acceptable tolerance range for the half-beam contacts. Confirm that the panel mounting footprint aligns with the mechanical design specifications.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations designed for general-purpose industrial applications. The 305 series is characterized by its durable construction and reliable performance in demanding environments, serving as a critical interconnect solution for modular electronic systems.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for direct substitutes with different position counts or contact spacings. Verify mechanical compatibility and electrical ratings before substituting with other manufacturers' products.
