TSW-121-08-T-D-RA

Headers, Male Pins Overview

The Samtec TSW-121-08-T-D-RA is a classic PCB header strip featuring 42 positions arranged in a dual-row configuration. It utilizes a 2.54 mm (0.100 inch) pitch and employs male pin contacts with tin plating. Designed for right-angle through-hole mounting, the connector supports board-to-board or cable applications. The housing is constructed from polybutylene terephthalate (PBT) with UL 94 V-0 flammability rating. Operating temperature ranges from -55°C to +125°C. Rated current varies by wire gauge, while voltage ratings include up to 550 VAC.

Headers, Male Pins Feature Summary

• Right-angle through-hole mounting for space-efficient PCB integration
• Dual-row design providing high density interconnect capability
• Tin-plated phosphor bronze contacts ensuring reliable signal transmission
• UL 94 V-0 rated PBT insulation for thermal stability

Headers, Male Pins Applications

• Board-to-board interconnections
• Cable-to-board connections
• General purpose electronic equipment
• Industrial control systems

Headers, Male Pins Procurement Notes

Verify the specific contact plating thickness and current rating requirements against the official Samtec datasheet for the TSW series. Confirm that the right-angle orientation and through-hole termination method align with the target PCB layout constraints. Ensure the operating temperature range meets the environmental specifications of the final assembly application before procurement.

Headers, Male Pins Selection Notes

Select this component when a standard 2.54 mm pitch header is required for right-angle mounting. The dual-row format maximizes connection density within limited board areas. Consider the tin plating for cost-effective applications where gold plating is unnecessary. Verify that the mechanical height and footprint are compatible with surrounding components on the assembly.

Headers, Male Pins Part Context

This part belongs to the TSW (Classic PCB Header Strips) series by Samtec. The series offers a wide range of position counts and row configurations. The TSW-121-08-T-D-RA specifically denotes a 42-position, dual-row variant with tin plating and right-angle termination. It serves as a fundamental interconnect solution in the broader Samtec connector portfolio.

Headers, Male Pins Replacement Considerations

Compatible substitutes within the same family include TSW-121-08-L-D-RA (gold plating) or TSW-121-08-S-D-RA (stainless steel contacts). Cross-series replacements like HTSW may differ in contact length and insulation material. Verify mechanical dimensions and electrical ratings before substituting.
