307-035-557-104

Edgeboard Connectors Overview

The EDAC Inc. 307-035-557-104 is a standard card edge connector from the 307 series, designed for reliable signal transmission in electronic assemblies. It features 70 positions with a 3.96 mm (0.156 inch) contact pitch and a 5.08 mm row spacing. The component accepts printed circuit boards with a nominal thickness of 1.57 mm. Constructed with gold plating on the mating area and tin plating on tails with nickel underplating, it ensures durability. The connector has a current rating of 5 amps and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified card types
• Gold-plated contacts for low resistance and corrosion resistance
• Thermoplastic housing material for structural integrity
• Vertical panel mount installation style

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment board-to-board connections
• Computing hardware peripheral interface modules
• Test and measurement instrumentation backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 307 Series Ordering Guide to ensure correct plating and termination specifications. Confirm that the required PCB thickness aligns with the 1.57 mm nominal design limit. Check RoHS compliance status via the manufacturer's environmental documentation before final procurement approval.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count vertical connector is required for dual-edge cards. Ensure the application environment stays within the -40°C to +105°C operating range. Verify that the 5 amp current rating per contact meets the circuit load requirements. Consider the 3.96 mm pitch compatibility with existing board layout constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 307 series of standard card edge connectors, which are widely used in modular electronic designs. The series offers various position counts and mounting styles to accommodate different form factors. The 307-035-557-104 specifically provides a robust solution for applications needing extensive I/O connections in a compact vertical profile.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 307 Series Ordering Guide for direct substitutes with differing pin counts or plating options. Cross-reference with other manufacturers' 0.156 inch pitch vertical headers if supply chain constraints require alternative sourcing.
