305-076-500-212

Edgeboard Connectors Overview

The EDAC Inc. 305-076-500-212 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features a dual-row configuration providing 76 positions with a contact spacing of 3.96 mm and a row spacing of 3.56 mm. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm. Contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. The unit utilizes a solder lug termination method and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row architecture supporting high-density interconnects
• Gold-plated copper alloy contacts for corrosion resistance
• Panel-mount design with vertical installation angle

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Automotive electronics demanding reliable thermal performance

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm exact termination style and housing material variations. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Confirm that the dual-row female configuration matches the mating card edge requirements. Cross-reference the insulation resistance rating of 5 GOhms with system safety standards. Validate that the operating temperature range meets the environmental conditions of the intended deployment site.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count interface is required in a compact vertical form factor. The 3.96 mm pitch allows for broader trace spacing compared to finer pitches, aiding in manufacturing yield. The thermoplastic housing provides necessary dielectric strength for industrial environments. Consider the solder lug termination if through-hole mounting on a chassis or backplane is preferred over surface mount techniques. Evaluate the 5 A current rating against the total load distribution across the dual rows.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which offers a modular approach to connectivity solutions. The series provides various position counts and mounting styles to accommodate diverse electronic enclosure designs. The 305 series is characterized by its consistent 3.96 mm contact spacing, ensuring interchangeability within the family while allowing customization through different suffix codes for specific mechanical and electrical requirements.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the EDAC 305 series include models with identical 76-position counts and 3.96 mm pitch, such as 305-076-500-504 or 305-076-500-212 variants. Verify that any alternative part number maintains the same dual-row female configuration and solder lug termination type. Ensure the replacement matches the specified 1.57 mm board thickness acceptance to guarantee proper mechanical retention.
