TSS-120-03-S-D

Headers, Male Pins Overview

The TSS-120-03-S-D is a vertical header connector from the Samtec Flex Stack TSS series. It features 40 positions arranged in two rows with a 0.100 inch (2.54 mm) pitch. The connector utilizes male pins made of phosphor bronze, terminated via through-hole soldering. Contact plating consists of gold over nickel for mating surfaces and matte tin over nickel for termination. It includes a four-wall shroud and keyway features for alignment. The unit operates within a temperature range of -55°C to 125°C and meets UL94 V-0 flammability standards.

Headers, Male Pins Feature Summary

• Low-profile design with a height of 0.365 inches (9.27 mm)
• Four-wall shrouded housing ensures precise pin alignment
• Gold-plated contacts provide reliable signal transmission
• Keyed interface prevents incorrect mating orientation

Headers, Male Pins Applications

• High-density board-to-board interconnections
• Backplane connectivity systems
• Industrial control module interfaces
• Communication equipment internal connections

Headers, Male Pins Procurement Notes

Verify that the specific suffix matches the required contact plating and termination style. Confirm the physical dimensions align with the target PCB footprint. Ensure the operating temperature range suits the intended environment. Check RoHS compliance status if restricted substances are prohibited. Validate the shroud type against mating connector requirements.

Headers, Male Pins Selection Notes

Select this component when a low-profile vertical header is required for high-density applications. The gold plating offers superior conductivity compared to tin-only options. The two-row configuration maximizes pin count within a limited area. Consider the shrouded design for improved mechanical stability during insertion. Evaluate the thermal rating against system heat dissipation needs.

Headers, Male Pins Part Context

This part belongs to the Flex Stack TSS family, designed for space-constrained electronic assemblies. The series provides various configurations including right-angle and cable mate options. The TSS-120-03-S-D specifically addresses vertical mounting needs with robust contact materials. It complements other Samtec interconnect solutions for complete system integration.

Headers, Male Pins Replacement Considerations

Direct substitutes include TSS-120-03-L-D and TSS-120-03-G-D. Verify compatibility regarding contact plating thickness and material composition. Ensure the replacement maintains the same pitch and row configuration. Check dimensional tolerances to guarantee proper fit within the existing enclosure.
