Headers, Male Pins Procurement Notes

Verify the specific ordering suffix to confirm terminal plating specifications, as Fischer Elektronik variants may differ in coating materials such as gold or nickel-tin combinations. Confirm that the required contact length and insulation height align with the target assembly constraints. Ensure the through-hole footprint matches the PCB design guidelines provided in the official datasheet. Cross-reference the series designation to identify compatible mating connectors within the same product family.

Headers, Male Pins Selection Notes

Select this component when a single-row, 20-position male header is required for through-hole applications. The 2.54 mm pitch ensures compatibility with standard ribbon cables and mating sockets. Consider the tin plating for general-purpose use where high corrosion resistance is not critical. Evaluate the physical dimensions against available board space, noting the specific insulation height and overall contact length requirements for proper mechanical fit.

Headers, Male Pins Part Context

This part belongs to the SL 1 128 series of rectangular connectors from Fischer Elektronik. The series offers various position counts and plating options to suit different electrical and mechanical needs. As a male pin header, it serves as a primary interface point for connecting flexible or rigid printed circuit boards.
