Headers, Male Pins Procurement Notes

Verify the specific suffix 'K' indicates the standard untrimmed lead frame configuration as documented in the official datasheet. Confirm that the 'S' designation corresponds to the specified 30µin gold plating thickness for mating contacts. Ensure the reel packaging type matches production requirements. Cross-reference the part number against the latest manufacturer catalog to confirm current availability and compliance status before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a 1.27mm pitch quad row header is required for vertical board stacking. The 6.35mm stacking height suits applications needing moderate separation between PCBs. Choose the 'S' plating option for environments requiring higher corrosion resistance compared to flash plating. Ensure mating SOLC sockets are selected with compatible lead styles and locking mechanisms to maintain system integrity.

Headers, Male Pins Part Context

This part belongs to the TOLC series, designed specifically for high-density I/O connections. It pairs exclusively with SOLC socket counterparts to form a complete interconnect system. The series supports various stacking heights and plating options to accommodate different electrical and mechanical constraints in modern electronic assemblies.

Headers, Male Pins Replacement Considerations

Public confirmed substitute part numbers: None identified in verified documentation. The TOLC/SOLC pairing is proprietary to Samtec Inc. with unique geometry and locking mechanisms. Alternative solutions require full system redesign to match pitch, stacking height, and locking features.

Headers, Male Pins FAQ

What is the mating partner for the TOLC-145-02-S-Q-K-TR?

It mates with SOLC series quad row sockets, such as the SOLC-145-02-F-Q-LC-K-TR or similar configurations depending on the required locking clip and lead style.

Does this connector include alignment pins?

No, the base model TOLC-145-02-S-Q-K-TR does not include alignment pins. Alignment pins are available in variants with the '-A' suffix, which cannot be combined with locking clips.
