305-058-521-208

Edgeboard Connectors Overview

The EDAC Inc. 305-058-521-208 is a standard card edge connector from the 305 Series, designed for vertical panel mounting applications. This dual-row header features 58 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). It is engineered to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The connector utilizes copper alloy contacts with gold plating and employs a solder pin termination type. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or official manufacturer channels. Confirm that the specific suffix matches the required 58-position specification and gold plating variant. Check RoHS compliance documentation against current regulatory standards. Ensure storage conditions maintain integrity prior to assembly. Validate compatibility with target PCB thickness and mounting hole patterns before final procurement decisions.

Edgeboard Connectors Selection Notes

Select this model when a 58-position interface is required with 3.96 mm spacing. Consider the 1.57 mm board thickness constraint during mechanical design. Evaluate the 5 A current rating against system power requirements. Compare alternative series if different row spacing or contact counts are needed. Verify thermal performance limits align with operational environment specifications.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series offers various position counts while maintaining consistent 3.96 mm spacing and 1.57 mm board thickness compatibility. The 305 Series is widely used across industrial and commercial sectors for reliable PCB-to-panel connections. EDAC designs these connectors to meet rigorous durability standards for demanding applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other 305 Series variants with matching 58 positions and identical electrical parameters. Cross-reference part numbers such as 305-058-521-202 or 305-058-521-504 for similar configurations. Ensure replacement units maintain the same gold plating and solder pin termination style. Verify mechanical dimensions match existing panel cutouts and PCB layouts.
