305-038-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-038-521-204 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 38 positions arranged in a dual row configuration with a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts and a thermoplastic polyester insulator body. It supports solder pin termination and accommodates printed circuit boards with a nominal thickness of 1.57 mm. The unit is rated for 5 A current and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify that the specific suffix 204 corresponds to the required color coding and packaging format as defined by EDAC Inc. Confirm compatibility with the target PCB thickness of 1.57 mm before procurement. Ensure that the panel mount hole pattern matches the mechanical drawing specifications. Check RoHS compliance status against current regulatory requirements for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a 38-position dual-row interface is required with a 3.96 mm pitch. The vertical panel mount style is suitable for chassis-mounted applications where space efficiency is prioritized. The 5 A rating supports moderate power distribution needs. Consider the operating temperature range of -40°C to +105°C for environmental suitability.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of edgeboard connectors, which are characterized by their high-density configurations and durable construction. The series offers various position counts and termination options to accommodate diverse electronic assembly requirements. The 305-038-521-204 specifically addresses applications needing a mid-range pin count with standardized spacing.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pin counts and spacing, such as the 305-038-520-502 or 305-038-521-204 variants differing only in secondary attributes. Verify mechanical dimensions and electrical ratings match exactly before substitution.
