305-084-555-501

Edgeboard Connectors Overview

The EDAC Inc. 305-084-555-501 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 84 positions arranged in two rows with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm), fitting within a range of 0.054 to 0.070 inches. It utilizes gold-plated copper alloy contacts with a half-bead termination type and solder pin end connections. The housing is made of green thermoplastic polyester, rated for operation between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating non-specified dual-edge cards
• Low-profile insulator body constructed from green thermoplastic polyester
• Gold-plated copper alloy contacts with half-bead termination for reliable signal transmission
• Panel mount installation style with vertical orientation and threaded plug mounting features

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instruments needing high-density connection points
• Automotive electronics modules operating in varied temperature environments

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's ordering guide to confirm exact plating thickness and flange configuration. Ensure compatibility with the target PCB thickness of 0.062 inches nominal. Confirm that the panel cutout dimensions align with the connector's physical envelope. Check for RoHS3 compliance requirements if applicable to the final assembly. Validate that the solder pin termination method matches the intended manufacturing process.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count interface is required for dual-edge cards. The 3.96 mm pitch allows for broader trace routing compared to finer pitches. The vertical panel mount style is suitable for chassis-mounted backplanes or enclosure interfaces. Consider the 5 A current rating per contact for power distribution needs. The gold finish provides corrosion resistance for long-term reliability in harsh environments.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and termination options to suit different density requirements. The 305-084 variant specifically addresses applications needing 84 connection points. The design emphasizes mechanical stability through panel mounting and secure card retention.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series parts with identical 84-position configurations and matching pitch specifications. Verify that alternative components support the same 0.062 inch board thickness and dual-edge card type. Ensure that the replacement maintains the same vertical panel mount style and solder pin termination. Cross-reference flange hole patterns if fixed mounting is required.
