305-042-555-507

Edgeboard Connectors Overview

The EDAC Inc. 305-042-555-507 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 42 positions with a 0.156-inch (3.96 mm) pitch and supports two rows of contacts. The connector utilizes female half-beam contacts made of copper alloy, finished with gold plating on the mating area and tin plating on tails with nickel underplating. Rated for 5 amps current, it accommodates PCB thicknesses between 0.054 and 0.070 inches. The housing is constructed from thermoplastic polyester, offering a vertical panel mount style with solder lug termination.

Edgeboard Connectors Feature Summary

• Thermoplastic polyester insulation provides thermal stability
• Vertical panel mounting design facilitates structural integration

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm plating specifications and housing color. Ensure compatibility with the target PCB thickness range of 0.054 to 0.070 inches. Confirm that the 42-position dual-row layout matches the circuit board design requirements. Check RoHS compliance status if required by project regulations. Validate that the vertical panel mount orientation aligns with the mechanical assembly constraints.

Edgeboard Connectors Selection Notes

Select this component when a high-density 42-position interface is required for dual-edge cards. The 3.96 mm pitch offers robust spacing for industrial environments. Consider the 5-amp current rating for power distribution needs. The combination of gold and tin plating addresses both conductivity and cost-efficiency. Verify that the panel mount style fits the enclosure design compared to through-hole alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in row counts and position numbers. Similar parts in the series include 305-038-555-507 and 305-050-555-507, which share the same pitch and general construction but differ in contact count. The 305 series is widely used in modular electronic systems requiring durable connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include 305-042-520-202, which shares the 42-position dual-edge specification but may differ in housing color or specific flange details. Cross-manufacturer replacements require careful verification of pitch, contact type, and mounting dimensions to ensure mechanical and electrical compatibility.
