305-016-500-503

Edgeboard Connectors Overview

The EDAC Inc. model 305-016-500-503 is a standard card edge connector from the 305 series, designed for vertical panel mounting applications. It features a dual-row configuration with 16 positions and a contact spacing of 3.96 mm (0.156 inches). The row spacing measures 3.56 mm (0.140 inches), accommodating printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. This component utilizes solder pin termination for secure board attachment.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 16 positions for high-density interconnects
• Vertical panel mounting style for stable structural integration
• Gold-plated copper alloy contacts ensuring durable electrical performance
• Compatible with 1.57 mm nominal thickness printed circuit boards

Edgeboard Connectors Applications

• Industrial control system interface connections
• Telecommunications equipment backplane assemblies
• Test and measurement instrument module interfaces
• Computing hardware peripheral expansion slots

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required dual-row configuration and 16-position count before procurement. Confirm compatibility with the target PCB thickness of 1.57 mm and verify that the solder pin termination type aligns with the assembly process. Ensure the gold-plated contact specification meets the environmental requirements for the intended application environment.

Edgeboard Connectors Selection Notes

Select this connector when a vertical panel mount solution with a 3.96 mm pitch is required. The dual-row design supports higher I/O density compared to single-row alternatives within the same footprint constraints. Consider the 5 A current rating and operating temperature range of -40 C to +105 C for suitability in demanding industrial environments.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options while maintaining consistent 3.96 mm contact spacing. The 305 series is widely utilized in electronic systems requiring robust, low-profile interconnect solutions for card-based architectures.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the 305 series include models such as 305-018-500-503 or 305-016-520-503, provided the position count and termination type match the design requirements. Verify that any replacement maintains the same 3.96 mm pitch and 1.57 mm board thickness compatibility.
