305-016-520-203

Edgeboard Connectors Overview

The EDAC Inc. 305-016-520-203 is a standard card edge connector from the 305 series, designed for panel mount applications with vertical orientation. It features 16 positions arranged in a dual row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and accepts printed circuit boards with a thickness range of 0.054 to 0.070 inches (1.37 mm to 1.78 mm). Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic polyester
• Provides a 1800VACrms dielectric voltage rating for electrical isolation

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring vertical interconnection
• Industrial control systems utilizing double-edge card edge PCBs
• Test and measurement equipment interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 16-position dual-row configuration before procurement. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Ensure the application environment remains within the specified operating temperature limits of -40°C to +105°C. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for double-edge cards. The 3.96 mm pitch suits applications needing robust mechanical retention. Consider the 5 A current rating for power distribution needs. Verify that the housing material meets thermal requirements for the intended operational environment.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and row configurations. The series is characterized by its use of thermoplastic insulators and gold-plated contacts. Similar parts in the series differ primarily in the number of positions and specific mounting flange dimensions while maintaining consistent electrical ratings.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-018-520-203 or 305-014-520-203 if position count adjustments are necessary. Ensure any substitute maintains the same 3.96 mm pitch and dual-row layout to preserve PCB footprint compatibility.
