305-014-520-203

Edgeboard Connectors Overview

The EDAC Inc. 305-014-520-203 is a dual-row card edge connector designed for panel and through-hole mounting. It features 14 positions with a 0.156-inch (3.96mm) spacing. The connector accepts non-specified double-sided cards with thicknesses between 0.054 and 0.070 inches. Contacts are made of copper alloy with gold plating, offering a 5A continuous current rating and 1800VACrms insulation voltage. Operating temperature ranges from -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Gold-plated half-bead contacts ensure reliable signal transmission
• Thermoplastic polyester insulation provides stable dielectric properties
• Flush mount flange with top opening facilitates panel integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust I/O connections
• Telecommunications equipment backplanes
• Test and measurement instrumentation interfaces
• Automotive electronic modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 305 Series Ordering Guide to confirm contact configuration and flange style. Ensure compatibility with target PCB thickness and polarizing key requirements. Confirm RoHS3 compliance status if required by project specifications. Cross-reference manufacturer part numbers with distributor codes to avoid substitution errors during procurement.

Edgeboard Connectors Selection Notes

Select this component when a 14-position dual-row interface is required with standard 0.156-inch spacing. Consider the 5A current rating and high insulation voltage for power or signal integrity needs. Evaluate the flush mount flange design against available panel space constraints. Verify that the target card thickness falls within the specified 0.054 to 0.070-inch range for proper engagement.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for durability and precise alignment. The series supports various position counts and contact configurations. The 305-014 variant specifically addresses applications needing a compact 14-pin interface with high reliability standards for industrial environments.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series cross-reference documentation for direct substitutes. Verify identical pin count, pitch, and mounting style before considering alternatives. Ensure replacement parts maintain the same current rating and insulation voltage specifications.
