305-070-555-558

Edgeboard Connectors Overview

The EDAC Inc. 305-070-555-558 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features 70 positions arranged in a dual row configuration with a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. The unit supports a current rating of 5 A and utilizes a solder pin termination method for secure board attachment.

Edgeboard Connectors Feature Summary

• Dual-row female connector design accommodates double-sided card edge PCBs
• Gold-plated copper alloy contacts provide corrosion resistance and stable conductivity
• Panel mount vertical installation style ensures rigid structural support
• Thermoplastic insulator body offers mechanical stability within specified temperature ranges

Edgeboard Connectors Applications

• Industrial control system backplanes requiring robust interconnects
• Telecommunications equipment chassis modules
• Test and measurement instrumentation interfaces
• Automotive electronic control unit connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm insulation color and flange specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the solder pin termination matches the assembly process requirements. Cross-reference the RoHS status if environmental compliance is mandatory for the project.

Edgeboard Connectors Selection Notes

Select this component when a high-density 70-position interface is required for vertical panel mounting. The 3.96 mm pitch suits applications needing substantial contact count without excessive width. Consider the 5 A current rating for power distribution needs alongside signal lines. Verify that the dual-edge card type aligns with the system's PCB design constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for general-purpose industrial and commercial applications. The series provides various position counts and termination options to accommodate diverse board layouts. The 305 series is characterized by its durable thermoplastic housing and reliable gold-plated contact systems, ensuring long-term performance in demanding environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical position counts and pitch but different suffixes for color or flange variations, such as 305-070-555-568. Verify mechanical dimensions and electrical ratings before substituting. Alternative series like 315 or 355 may offer similar functionality but require checking for differences in row spacing and board thickness acceptance.
