TOLC-110-02-S-Q-LC

Headers, Male Pins Overview

The TOLC-110-02-S-Q-LC is a .050" (1.27mm) pitch FOURRAY Quad Row Terminal Strip designed for board-to-board and mezzanine applications. This surface mount header features 40 positions arranged in four staggered rows, providing a high-density interconnect solution. The connector utilizes phosphor bronze contacts with gold plating on both the mating and post surfaces to ensure reliable signal transmission. It is rated for 2.4A per contact and operates within a temperature range of -55°C to 125°C. The housing is constructed from black liquid crystal polymer (LCP) with a UL94 V-0 flammability rating, offering mechanical stability and thermal resistance for demanding electronic environments.

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against official Samtec documentation to confirm exact configuration details. Ensure that the selected variant matches the required contact length, insulation height, and termination style for your design. Cross-reference the part number with the manufacturer's current datasheet to confirm availability status and compliance certifications before finalizing procurement plans.

Headers, Male Pins Selection Notes

Select this component when a .050" pitch quad row header is required for vertical surface mount assembly. Confirm compatibility with mating sockets such as the Tiger Buy™ series to ensure proper engagement. Evaluate the 6.35mm stacking height and 0.100" contact length specifications against your PCB stack-up constraints. Verify that the 2.4A current rating and LCP material properties align with your thermal and electrical performance requirements.

Headers, Male Pins Part Context

This part belongs to the TOLC series, which represents Samtec's .050" FOURRAY Quad Row Terminal Strip line. The series is engineered for high-density interconnect solutions where space is limited but multiple connections are necessary. The TOLC family offers various configurations to support different board-to-board and mezzanine applications, providing flexibility in row count and position numbers while maintaining consistent pitch and mounting characteristics.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other .050" pitch quad row headers from Samtec, such as the TOLC-110-02-S-Q-K or TOLC-110-02-S-Q-LC-K variants. Ensure that any replacement maintains the same 40-position count, surface mount termination, and gold-plated contact specifications to guarantee functional equivalence in the existing design.
