What are the key features of TSM-141-04-G-DV-P-TR?
- 82-position dual-row layout at standard 0.100" (2.54 mm) pitch for robust high-count board-to-board signal and power distribution
- Polarization peg (-P suffix) prevents reverse mating on 82-pin interfaces, eliminating costly mis-insertion damage in field-service applications
- Tape-and-reel (-TR) packaging enables high-volume automated pick-and-place assembly on standard SMT production lines
What is TSM-141-04-G-DV-P-TR used for?
The TSM-141-04-G-DV-P-TR is designed for high pin-count board stacking and backplane distribution applications in industrial controllers, telecom chassis, and embedded computing platforms where 82 signals must be reliably routed between PCBs at standard 0.100" pitch. The dual-voltage configuration allows power and signal contacts to coexist in one connector body, reducing the number of separate connectors on congested PCBs. Tape-and-reel packaging makes it straightforward to scale production with pick-and-place equipment.

Frequently Asked Questions
What pitch does TSM-141-04-G-DV-P-TR use and how does that affect PCB layout density compared to 0.050" pitch alternatives?
The TSM-141-04-G-DV-P-TR uses 0.100" (2.54 mm) pitch, which is twice the spacing of 0.050" pitch connectors. An 82-position 0.100" dual-row connector spans approximately 2.1" in body length versus about 1.05" for the equivalent 0.050" pitch part, trading density for easier manual assembly, wider trace routing between pads, and compatibility with legacy PCB designs constrained to 0.100" grid layouts.
For a 64-bit bus plus power and control signals, does TSM-141-04-G-DV-P-TR provide enough positions?
Yes. An 82-position connector accommodates a 64-bit data bus alongside 8 address lines, 4 control signals, 3 power pins, and 3 ground returns within a single connector, eliminating the need for a second connector body. This consolidation reduces BOM complexity and simplifies PCB routing compared to pairing two smaller 40-position connectors.
What does the dual-voltage (-DV) designation mean for the TSM-141-04-G-DV-P-TR?
The dual-voltage (-DV) designation indicates the connector supports two voltage domains within the same 82-position body, allowing designers to route, for example, 3.3 V digital I/O and 5 V power rails through physically separated contact zones in a single mated pair. This eliminates the need for a dedicated power connector alongside the signal connector, saving board space and reducing assembly steps.
How does the polarization peg on TSM-141-04-G-DV-P-TR reduce risk in field-replaceable board assemblies?
The polarization peg physically blocks 180-degree reverse insertion into the mating header, preventing power and ground reversal on an 82-pin interface that could instantly damage connected ICs. In rack-mount systems where technicians replace modules under time pressure, this mechanical keying feature eliminates a common cause of field failures without requiring additional board modifications or assembly steps.
