- Thermoplastic polyester housing provides high-temperature stability
Applications
- Computing and storage systems
- Industrial control modules
- Communications network equipment
Procurement Notes
Verify the specific ordering suffix against the manufacturer datasheet to confirm plating type and row configuration. Ensure the target PCB or card thickness matches the specified 1.57 mm requirement. Confirm that the panel mount style aligns with the mechanical assembly constraints. Check RoHS compliance status directly on the product specification sheet before finalizing procurement orders.
Selection Notes
Select this component when a dual-edge connection is required for robust signal integrity in vertical panel mounts. The 3.96 mm pitch accommodates standard card edge widths. Verify that the 5 A current rating meets the circuit load requirements. Consider the operating temperature range if the environment exceeds standard industrial limits.
Part Context
This part belongs to the EDAC 306 series of card edge connectors, established as a leader in interconnect solutions since 1966. The series offers extensive options for contact terminations, mounting styles, and guide solutions. EDAC products serve global OEMs in computing, medical, aerospace, and clean technology sectors, emphasizing rigorous quality assurance and FIFO inspection protocols.
Replacement Considerations
Cross-reference with other EDAC 306 series variants such as 306-027-420-158 for similar physical dimensions but different packaging or row configurations. Verify compatibility with existing tooling and PCB layouts before substitution.
