305-028-556-503

Edgeboard Connectors Overview

The EDAC Inc. 305-028-556-503 is a standard card edge connector from the 305 series, designed for vertical panel mount applications. It features 28 positions with a 3.96 mm (0.156 inch) pitch and dual rows of female contacts. The connector utilizes gold-plated copper alloy terminals with solder pin termination to ensure reliable electrical connections. It accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The housing is constructed from thermoplastic polyester, providing durability and insulation. Rated for 5 A continuous current, it 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 contact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a 28-position interface with a 3.96 mm pitch is required. The dual-row female configuration supports high-density board connections. Consider the 5 A current rating for power distribution needs. The vertical orientation dictates the mounting geometry relative to the chassis. Verify that the operating temperature range meets the environmental conditions of the intended application site.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations for diverse connectivity needs. The 305 series is characterized by its durable construction and reliable performance in demanding environments. Similar parts in the series differ primarily in the number of positions and specific mounting variations.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants having identical 28-position counts and 3.96 mm pitch. Verify mechanical footprint and terminal spacing compatibility before substitution. Ensure equivalent electrical ratings and material specifications are maintained.
