TSW-121-05-L-D

Headers, Male Pins Overview

The TSW-121-05-L-D is a classic PCB header strip manufactured by Samtec Inc. It features a 0.100 inch (2.54 mm) pitch and consists of 42 positions arranged in two rows. The connector utilizes phosphor bronze contacts with gold plating on the mating interface, ensuring reliable electrical performance. Designed for through-hole mounting, it offers a straight orientation suitable for board-to-board or cable applications. The housing is constructed from polybutylene terephthalate (PBT), providing UL 94 V-0 flammability rating. Operating temperatures range from -55°C to +125°C.

Headers, Male Pins Feature Summary

• Classic design allows for easy cutting to custom lengths
• Gold-plated phosphor bronze contacts ensure durability
• Straight through-hole termination for secure PCB mounting

Headers, Male Pins Applications

• Board-to-board interconnections
• Cable connections
• General purpose electronic assemblies

Headers, Male Pins Procurement Notes

Verify the specific contact plating thickness and terminal length requirements against the official datasheet before procurement. Confirm that the standard 0.100 inch pitch aligns with the target PCB footprint. Ensure the operating temperature range meets the environmental conditions of the final application. Cross-reference the RoHS compliance status with current regulatory standards.

Headers, Male Pins Selection Notes

Select this component when a standard, cost-effective header is required for low-speed digital signals. The two-row configuration provides high density within a minimal footprint. Consider the straight orientation for vertical stacking or direct panel mounting. Verify that the 42-position count matches the circuit design needs without requiring additional connectors.

Headers, Male Pins Part Context

This part belongs to the TSW series of classic PCB header strips from Samtec. The series is known for its versatility and wide availability across various pin counts and row configurations. It serves as a fundamental interconnection solution in general electronics manufacturing, offering a balance of performance and ease of use for standard assembly processes.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Samtec TSW headers with identical pitch and position counts, such as TSW-121-05-S-D or TSW-121-05-G-D, depending on contact material preferences. Ensure any replacement maintains the same 0.100 inch pitch and through-hole termination style to fit existing footprints.
