TSW-121-23-T-D

Headers, Male Pins Overview

The Samtec TSW-121-23-T-D is a classic PCB header strip featuring 42 positions arranged in two rows. It utilizes a 2.54 mm (0.100 inch) pitch with square male pin contacts. Designed for through-hole mounting, the connector employs tin-plated phosphor bronze terminals housed in polybutylene terephthalate (PBT). The unit supports a straight orientation and operates within a temperature range of -55°C to +105°C. Electrical ratings include current capacities up to 6.3 A and voltage ratings reaching 550 VAC, ensuring reliable board-to-board or cable interconnections.

• Features .025-inch square post terminal design for secure mating
• Provides extensive lead style and plating options for design flexibility
• Utilizes ruggedized features to optimize cost and performance

Headers, Male Pins Applications

• Board-to-Board interconnections
• Cable connections
• Retrofit applications

Headers, Male Pins Procurement Notes

Verify that the specific ordering suffix matches the required contact plating and lead length specifications. Confirm that the housing material and termination style align with the target assembly process. Ensure compliance with RoHS and UL requirements for the intended deployment environment. Cross-reference dimensional drawings against the PCB footprint to guarantee mechanical fit before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a standard vertical header with through-hole termination is required. The 42-position configuration suits dense circuit layouts needing dual-row connectivity. Tin plating offers a cost-effective solution for general-purpose environments. Consider alternative series if surface mount or right-angle orientations are necessary for the specific board layout constraints.

Headers, Male Pins Part Context

This part belongs to the TSW series of classic PCB header strips from Samtec. The series provides a wide variety of standard pin counts and terminal lengths. It serves as a fundamental interconnect solution for electronics manufacturing, balancing reliability with manufacturing efficiency. The TSW designation indicates a specific terminal strip configuration within the broader Samtec connector portfolio.

Headers, Male Pins Replacement Considerations

Compatible substitutes include TSW-121-23-S-D and TSW-121-23-G-D from the same manufacturer. These alternatives maintain identical mechanical dimensions and pin counts while differing in contact plating materials. Verify that any replacement part meets the same electrical ratings and environmental specifications.
