Procurement Notes
Verify the specific ordering suffix to confirm contact plating type, as variations exist within the 306 series. Confirm that the required board thickness matches the 1.57 mm specification. Ensure the application environment does not exceed the thermal limits of the thermoplastic polyester material. Cross-reference the pin count against the target PCB layout to guarantee compatibility with the 52-position requirement.
Selection Notes
Select this component when a dual-edge connection is required for a 52-line interface. The 3.96 mm pitch dictates the minimum trace spacing on the mating PCB. Consider the tin plating if lead-free soldering processes are mandated. Evaluate the vertical mounting style against available panel space constraints compared to surface mount alternatives.
