305-018-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-018-521-502 is a standard card edge connector from the 305 series, designed for vertical panel mount applications. It features a dual female configuration with 18 positions and a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts with a solder pin termination type. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic polyester, providing robust insulation.

Edgeboard Connectors Feature Summary

• Dual row female contact configuration for non-specified dual-edge cards
• Vertical panel mount installation style with solder pin termination
• Gold-plated copper alloy contacts ensuring reliable signal transmission
• Thermoplastic polyester housing material for structural integrity

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment board-to-board connections
• Automotive electronics modules needing durable panel interfaces
• Test and measurement instrumentation internal wiring

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 18-position dual-row specification and 3.96 mm pitch. Confirm the gold plating thickness and copper alloy contact material align with system requirements. Ensure the vertical panel mount style and solder pin termination are compatible with the assembly process. Check RoHS compliance status if environmental regulations apply to the project scope.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with a 3.96 mm pitch is required. The vertical orientation suits panel-mounted designs where space efficiency is critical. The 5 A rating supports moderate power distribution needs. Consider the thermoplastic housing for general-purpose industrial environments. Validate that the solder pin termination method fits the PCB manufacturing capabilities.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and mounting options. The series is characterized by its standardized 3.96 mm pitch and robust construction. Similar parts in the series may differ in position count or termination style but share the same fundamental design philosophy for card edge applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with identical 18-position dual-row specifications and 3.96 mm pitch. Verify compatibility regarding mounting style and termination type before substitution. Cross-reference with manufacturer datasheets to ensure electrical and mechanical parameters match exactly.
