305-016-555-203

Edgeboard Connectors Overview

The EDAC Inc. 305-016-555-203 is a standard card edge connector from the 305 Series, designed for reliable signal and power transmission in electronic assemblies. This dual female header features 16 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). It accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The connector supports a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage. Constructed with copper alloy contacts gold-plated for conductivity, it utilizes a thermoplastic polyester insulator body rated for operation between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body design minimizes vertical space requirements
• Gold-plated copper alloy contacts ensure stable electrical performance

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interfaces
• Telecommunications equipment utilizing standardized card edge form factors
• Test and measurement instrumentation needing high-density connections

Edgeboard Connectors Procurement Notes

Verify the specific pin count and orientation against your PCB footprint before ordering. Confirm that the target application environment stays within the specified temperature range of -40°C to +105°C. Ensure compatibility with the required polarizing key type if mechanical locking is necessary. Check RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a 16-position dual-row interface is required for 0.062-inch thick boards. The 3.96 mm pitch suits applications needing wider spacing than standard 0.1-inch connectors. Consider the 5A current rating for power distribution needs. Verify that the vertical or straight mounting style matches your chassis constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for durability and versatility. The series offers various position counts and mounting styles to support diverse electronic design requirements. These connectors are widely used in modular electronics where reliable interconnection between backplanes and daughter cards is essential.

Edgeboard Connectors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 16-position count, 3.96 mm pitch, and 1.57 mm board thickness specifications precisely.
