What are the key features of TSM-144-02-TL-DV-P-TR?
- 88-position dual-row layout on industry-standard 2.54 mm (0.100 inch) pitch for broad mating connector compatibility
- Tin-lead (TL) contact finish option for applications where lead-free solder processes are not mandated, ensuring excellent solderability
- Tape-and-reel (TR) packaging and positioning post (P) alignment feature enable automated SMT assembly for high-volume PCB manufacturing
What is TSM-144-02-TL-DV-P-TR used for?
The TSM-144-02-TL-DV-P-TR serves as a high pin-count board-to-board or wire-to-board interface in industrial control backplanes, legacy instrumentation systems, and embedded computing platforms where 2.54 mm pitch compatibility with existing designs is required. The 88 dual-row positions accommodate large signal buses including address, data, and control lines for parallel interface devices. Tape-and-reel packaging and positioning posts ensure consistent automated placement on standard SMT lines, reducing connector placement errors and rework costs.

Frequently Asked Questions
What distinguishes the TSM-144-02-TL-DV-P-TR from the gold-finish TSM-144-03-G-DV-P-TR variant?
The TSM-144-02-TL-DV-P-TR uses tin-lead (TL) contact finish, while the TSM-144-03-G variant uses gold plating. Tin-lead finish provides reliable solderability for wave and reflow processes in non-RoHS environments, whereas gold plating reduces contact resistance for high-cycle mating. Both carry 88 positions at 2.54 mm pitch, so selection depends on finish compatibility with the solder process and mating connector requirements.
How do the positioning posts on TSM-144-02-TL-DV-P-TR assist in SMT manufacturing?
The P suffix positioning posts insert into small PCB holes before reflow, mechanically locking the 88-position 2.54 mm pitch body in place against lateral movement during the solder thermal cycle. This prevents pad misalignment across the full 88-position length and eliminates the need for adhesive or manual holding fixtures during reflow, improving first-pass yield on automated SMT lines.
In which system types would an engineer select the 88-position TSM-144-02-TL-DV-P-TR over a smaller terminal strip?
An 88-position count at 2.54 mm pitch is appropriate for parallel bus architectures such as 32-bit address plus 32-bit data plus control signals on backplane connectors, or for multi-channel sensor arrays requiring dedicated signal and ground returns. Industrial PLCs, VME-style card cages, and legacy test equipment backplanes using 0.100 inch grid layouts benefit from this part's pin density without requiring a denser, more expensive fine-pitch connector technology.
