Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the official Fischer Elektronik datasheet to confirm contact count and plating type. Ensure the selected variant matches the required pitch and current rating for the target application. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by project specifications.

Headers, Male Pins Selection Notes

Select this component based on the 2.54 mm pitch requirement and 21-contact capacity. Evaluate the thermal endurance limits against the manufacturing soldering profile. Consider the CuSn alloy material properties for mechanical durability. Assess the voltage ratings against the system's electrical environment to ensure safety margins are met during operation.

Headers, Male Pins Part Context

This header belongs to the Fischer Elektronik SL series of card edge connectors and headers. The series provides standardized solutions for PCB-to-PCB or PCB-to-cable connections. The SL 1 230 designation indicates specific dimensional and electrical characteristics within the broader product family designed for reliable signal and power transmission.

Headers, Male Pins Replacement Considerations

Direct substitutes include variants within the same SL 1 230 series with different contact counts, such as SL 1 230 2 Z or SL 1 230 3 S. Verify pin compatibility and housing dimensions before swapping. Alternative manufacturers may offer similar pitch connectors but require validation of electrical ratings and mechanical fit.
