305-076-520-203

Edgeboard Connectors Overview

The EDAC Inc. 305-076-520-203 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 76 positions with a 3.96 mm (0.156 inch) pitch and supports two contact rows. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator body. Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C. The unit employs a solder pin termination method and accepts PCB thicknesses between 1.37 mm and 1.78 mm.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Dual-row female configuration with gold-plated copper alloy contacts
• Low-profile insulator body constructed from thermoplastic polyester

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Automotive electronic modules
• Test and measurement instrumentation

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm compatibility with required polarization keys and mounting styles. Ensure the target printed circuit board thickness falls within the specified acceptance range of 1.37 mm to 1.78 mm prior to procurement. Confirm that the application environment remains within the operational temperature limits defined by the component specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with a 3.96 mm pitch is required. The 305 series design accommodates polarizing keys, which is critical for applications demanding precise board insertion orientation. Verify that the 5 A current rating and 1800 VACrms insulation voltage meet the system's electrical requirements. Consider the panel mount or PCB mount style based on the mechanical assembly constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. The series provides various position counts while maintaining consistent 3.96 mm spacing and dual-row configurations. These connectors are engineered for high-reliability applications, featuring durable gold plating and thermoplastic polyester housings suitable for harsh industrial environments.

Edgeboard Connectors Replacement Considerations

Cross-reference compatible parts within the EDAC 305 series family that share the same 76-position count and 3.96 mm pitch. Verify mechanical footprint and electrical ratings before substitution.
