TOLC-140-12-S-Q-A-K

Headers, Male Pins Overview

The TOLC-140-12-S-Q-A-K is a quad row surface mount terminal strip from the Samtec FOURRAY series. It features 140 positions with a 0.050-inch (1.27 mm) pitch across four rows. The connector utilizes phosphor bronze contacts with gold plating and liquid crystal polymer insulation. Rated for 2.4 A per contact, it operates within a temperature range of -55°C to +125°C. Key specifications include a mating length of 0.100 inches, an insulator height of 0.285 inches, and a stacking height of 8 mm. It employs a push-pull locking mechanism and offers four-wall shielding.

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against official Samtec documentation to confirm material composition and plating thickness. Ensure compatibility with mating SOLC series connectors. Confirm RoHS compliance status and moisture sensitivity level requirements for your manufacturing process before procurement.

Headers, Male Pins Selection Notes

Select this component when high I/O density is required in a vertical stack-up configuration. The quad row architecture maximizes pin count per unit area compared to dual-row alternatives. Consider the 8 mm stacking height constraint and ensure sufficient clearance for adjacent components on both PCB layers.

Headers, Male Pins Part Context

This part belongs to the TOLC series of .050 inch pitch quad row terminals. It is designed for applications demanding reliable signal transmission in space-constrained environments. The series supports various tail lengths and plating options to meet diverse electrical and mechanical performance criteria.

Headers, Male Pins Replacement Considerations

Compatible mating connectors are found in the SOLC series. Verify that alternative parts maintain identical pitch, row count, and locking mechanism characteristics to ensure mechanical fit and electrical continuity without redesigning the PCB footprint.
