305-070-521-508

Edgeboard Connectors Overview

The EDAC Inc. 305-070-521-508 is a standard card edge connector from the 305 Series, designed for vertical panel mounting. It features a dual-row configuration with 70 positions and a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches) and utilizes gold-plated copper alloy contacts. Rated for 5 A continuous current, it supports a maximum operating temperature of +105°C and a minimum of -40°C. The insulator body is constructed from green thermoplastic material.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm the exact termination style and plating specifications required for the application. Confirm that the panel mount orientation matches the mechanical constraints of the enclosure. Ensure the selected variant aligns with the required PCB thickness tolerance of 1.57 mm. Cross-reference the manufacturer datasheet for any recent updates to the product line or environmental compliance status before finalizing the procurement order.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required for panel-mounted applications. The 70-position count provides a specific channel density suitable for complex signal routing. Consider the 5 A current rating and thermal range if the environment involves moderate heat generation. Verify compatibility with existing polarizing key requirements to ensure proper mating with the corresponding card edge PCB.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting options and row configurations. The series is characterized by its 3.96 mm contact spacing and robust construction for reliable connections. The 305-070-521-508 specifically denotes the 70-position, dual-row variant with gold contacts and a green thermoplastic housing, fitting within the broader portfolio of standard card edge connectors.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other 305 Series variants with different position counts, such as 305-048-521-508 or 305-030-521-501, provided the pin count can be adapted. Ensure any replacement maintains the 3.96 mm pitch and 1.57 mm board thickness compatibility.
