What are the key features of TSM-121-04-H-DH-P-TR?
- 42-position dual-row surface mount terminal strip with 2.54 mm (0.100 inch) pitch
- High-profile (H) standoff for increased clearance between mated boards
- Tape and reel packaging for automated SMT pick-and-place assembly
- Standard 0.100 inch pitch for compatibility with common mating headers and development boards
- Surface mount termination for robust soldered PCB attachment
- Dual-row configuration for high pin density in compact form factors
What is TSM-121-04-H-DH-P-TR used for?
The TSM-121-04-H-DH-P-TR is used in development kits, processor expansion boards, and modular I/O systems where a 42-position dual-row, 2.54 mm pitch interface is required. The high-profile standoff variant provides additional vertical clearance between boards, making it suitable for applications where components or flex cables must pass beneath the mated connector stack.

Frequently Asked Questions
What does the H designation mean in the TSM-121-04-H-DH-P-TR part number, and how does it affect board clearance?
The H in TSM-121-04-H-DH-P-TR designates a high-profile standoff version of the terminal strip. This increases vertical clearance between mated PCBs, which is important when surface-mounted components or wiring routed beneath the 42-position connector need additional space to avoid mechanical interference during assembly.
How many positions and what pitch does the TSM-121-04-H-DH-P-TR terminal strip have?
The TSM-121-04-H-DH-P-TR is a 42-position surface mount terminal strip with 2.54 mm (0.100 inch) pitch in a dual-row configuration. This standard pitch is compatible with a wide range of mating headers, development boards, and wire-to-board connectors used in embedded and prototyping environments.
Is the TSM-121-04-H-DH-P-TR supplied in a format suitable for high-volume automated PCB assembly?
Yes. The TSM-121-04-H-DH-P-TR is supplied in tape and reel format, which is compatible with standard SMT pick-and-place equipment. The surface mount termination style and reel packaging enable efficient automated placement in high-volume PCB manufacturing for 42-pin interface connectors on production boards.
