305-068-500-503

Edgeboard Connectors Overview

The EDAC Inc. 305-068-500-503 is a standard card edge connector designed for panel mounting applications. It features a dual female configuration with 68 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and accommodates a board thickness of 1.57 mm. Contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. The termination method employs solder eyelets, and the housing is made of green thermoplastic polyester. The component supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C.

• Panel mount installation style with vertical orientation
• Solder eyelet termination for secure PCB attachment

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interfaces
• Test and measurement instrument modules
• Computer peripheral expansion cards

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact plating and housing color specifications. Confirm that the panel cutout dimensions align with the connector's mechanical envelope. Ensure the mating card edge thickness falls within the specified tolerance to guarantee proper contact engagement. Cross-reference the manufacturer datasheet for any recent design changes or compliance updates before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, panel-mount interface is required for thick circuit boards. The 3.96 mm pitch dictates the trace spacing requirements on the mating card. Verify that the application environment stays within the -40°C to +105°C operating range. Consider the 5 A current rating per contact when designing power distribution networks. Ensure the solder eyelet termination process is compatible with the assembly line capabilities.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-068-500-503 specifically denotes a 68-position dual-row variant. Similar parts in the series differ by position count, such as the 305-020 or 305-038 models. The series is characterized by robust thermoplastic housings and standardized pin layouts.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with identical 68-position dual-row configurations. Verify compatibility with mating cards having 1.57 mm thickness. Check if alternative suppliers offer equivalent specs for pitch and current rating. Ensure the replacement maintains the same panel mount orientation and solder eyelet termination type.
