305-080-555-503

Edgeboard Connectors Overview

The EDAC Inc. 305-080-555-503 is a standard card edge connector from the 305 Series, designed for dual-edge female applications. It features 80 positions with a 3.96 mm (0.156 inch) pitch and a row spacing of 3.56 mm (0.140 inch). The connector accepts printed circuit boards with a thickness range of 1.37 mm to 1.78 mm (0.054" to 0.070"). Constructed with copper alloy contacts featuring gold plating, it supports a current rating of 5 A. The unit utilizes a thermoplastic polyester insulator and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact physical dimensions and termination type. Ensure compatibility with the target PCB thickness specifications before procurement. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market. Confirm that the vertical panel mount style aligns with the mechanical design constraints of the final assembly enclosure.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with an 80-position count is required. The 3.96 mm pitch must match the design rules of the mating card edge PCB. Consider the 5 A current rating and operating temperature range to ensure electrical safety under load. Verify that the panel mount orientation fits the available space within the system housing without interference.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides a range of standard card edge connectors. The series includes various position counts and mounting styles to support diverse electronic packaging needs. The 305-080 variant specifically addresses applications requiring higher pin counts while maintaining the standard 3.96 mm spacing characteristic of this product line.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 305-080-555-568, which shares similar electrical characteristics but may differ in flange features or color coding. Always verify mechanical fit and terminal type equivalence before substitution.
