Overview
The EDAC Inc. 306-021-500-158 is a standard card edge connector designed for vertical panel mount applications. It features 21 positions with a contact spacing of 3.96 mm (0.156 inches). The connector utilizes a single centerline row configuration and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The insulator body is constructed from low-profile material, and the contacts are gold-plated to ensure reliable electrical performance.
Feature Summary
- Vertical panel mount installation style
- Single centerline row contact configuration
- Low profile insulator body design
Applications
- Standard card edge interconnects
- Embedded system board connections
- Microcontroller peripheral interfaces
Procurement Notes
Verify the specific ordering suffix against the manufacturer datasheet to confirm exact pin count, plating specifications, and mounting orientation. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Cross-reference the DigiKey or Mouser part numbers with official EDAC documentation to validate component authenticity and current availability status.
Selection Notes
Select this component when a vertical panel mount solution is required for single-row card edge applications. The 3.96 mm pitch accommodates standard board thicknesses, while the low-profile body minimizes spatial requirements. Confirm that the single centerline row aligns with the signal routing topology and that the gold plating meets the environmental durability requirements for the intended operational conditions.
Part Context
This component belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and pitch options tailored for general-purpose interconnect needs. The 306-021 variant specifically addresses applications requiring a compact 21-position interface with robust mechanical stability for panel-mounted configurations.
Replacement Considerations
Direct substitutes within the same series include the 306-021-500-101 and 306-021-521-158. Verify that alternative part numbers match the required 21-position count, 3.96 mm pitch, and vertical mounting orientation before substitution.
