305-040-555-258

Edgeboard Connectors Overview

The EDAC Inc. 305-040-555-258 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features a dual-row configuration with 40 positions and a contact pitch of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts that are gold-plated, it ensures reliable electrical performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 40 positions for high-density interconnects
• Vertical panel mount style with solder pin termination for secure installation
• Gold-plated copper alloy contacts ensuring durability and conductivity
• Compatible with nominal 1.57 mm thick PCBs

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation needing reliable signal transmission
• Automotive electronics applications with specific thermal requirements

Edgeboard Connectors Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to confirm compatibility with specific PCB thicknesses and mounting variations. Ensure that the required contact plating thickness meets the application's wear resistance standards. Cross-reference the RoHS compliance status with regional regulatory requirements before finalizing procurement orders to avoid supply chain disruptions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 40-position interface is required for vertical panel mounting. The 3.96 mm pitch suits applications needing wider spacing between contacts compared to finer pitches. Verify that the target PCB thickness aligns with the 1.57 mm nominal specification to ensure proper mechanical retention. Consider the 5A current rating and temperature range for environmental suitability in the intended deployment scenario.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which offers various row counts and mounting options. The series is characterized by its thermoplastic insulator body and standardized dimensions. The 305-040-555-258 specifically addresses the need for a 40-position dual-row connector, fitting into the broader catalog alongside other position variants like 305-048 and 305-054.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with different position counts such as 305-048-555-258 or 305-054-555-258 if higher density is needed. For identical specifications, verify cross-manufacturer equivalents that match the 3.96 mm pitch and dual-row layout. Ensure any replacement maintains the same panel mount orientation and solder pin termination type.
