305-026-555-508

Edgeboard Connectors Overview

The EDAC Inc. 305-026-555-508 is a standard card edge connector featuring 26 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for female contact interfaces. The unit employs gold-plated copper alloy contacts with a solder lug termination type, ensuring reliable electrical performance. Constructed with a thermoplastic housing, it supports panel mounting in a vertical orientation. The connector accommodates PCB thicknesses within the range of 1.37 mm to 1.78 mm and operates effectively between -40°C and +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact plating thickness and housing color specifications. Ensure that the target application environment remains within the stated temperature range and that the PCB thickness aligns with the connector's acceptance criteria. Confirm RoHS compliance status directly from the official documentation prior to final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required for vertical panel mounting applications. The choice is appropriate for systems needing gold-plated contacts for enhanced durability and reliability. Consider the specific thermal and mechanical constraints of the installation site to ensure compatibility with the connector's operating temperature range and mounting style requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely utilized in industrial and commercial electronics. The series offers various position counts and mounting options to accommodate diverse circuit board designs. The 305 series is recognized for its robust construction and consistent performance in demanding environments, providing a reliable solution for high-density interconnect needs.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching pitch and position counts, such as the 305-018-555-508 or 305-080-555-568, provided the pin count matches the design requirements. Cross-brand replacements require careful verification of pitch, row configuration, and mounting style to ensure functional equivalence without redesigning the host PCB footprint.
