What are the key features of TSM-142-04-FM-DV-P-TR?
- 84 positions in a dual-row 0.100-inch (2.54 mm) pitch layout for high pin-count backplane and daughtercard interconnects on the industry-standard 2.54 mm grid
- FM (full-metal) contact shielding reduces EMI coupling between adjacent signal pairs, improving crosstalk performance in mixed-signal and high-speed digital designs
- Dual-voltage (DV) body supports two independent voltage planes within one 84-pin connector, reducing total connector count on complex power distribution boards
- P polarization post prevents 180-degree mismating in dense multi-connector panel layouts, protecting boards during manual assembly and field maintenance
- Tape-and-reel (TR) packaging enables high-throughput automated pick-and-place placement for consistent 0.100-inch pitch pad alignment across production volumes
What is TSM-142-04-FM-DV-P-TR used for?
The TSM-142-04-FM-DV-P-TR serves industrial backplane systems, server blade power distribution boards, and embedded computing carrier cards requiring an 84-pin dual-row surface-mount connector with EMI-attenuating full-metal contacts. Its dual-voltage configuration makes it effective for simultaneously routing separate power supply rails—such as 5 V and 3.3 V—through a single connector body, simplifying power bus layout in complex multi-rail designs. The tape-and-reel format supports high-volume SMT production lines for communication infrastructure and industrial control equipment.

Frequently Asked Questions
What does the FM designation mean in TSM-142-04-FM-DV-P-TR and how does it reduce interference?
FM in the SAMTEC TSM part number stands for full-metal shield contact housing, where metallic tabs or walls surround individual signal contacts within the 0.100-inch (2.54 mm) pitch body. This shielding reduces capacitive and inductive crosstalk between adjacent pins, improving signal integrity for mixed analog-digital designs or high-speed parallel buses where coupling between 84 closely-spaced contacts at 2.54 mm pitch would otherwise degrade signal quality at frequencies above 100 MHz.
How many positions does TSM-142-04-FM-DV-P-TR have and what does the dual-row layout enable?
The TSM-142-04-FM-DV-P-TR has 84 total positions in a dual-row (2×42) arrangement at 0.100-inch (2.54 mm) pitch. The dual-row layout allows routing of 84 independent signals, power, and ground connections through a single connector body measuring approximately 4.2 inches in length, enabling dense backplane designs that consolidate power distribution and multi-bus digital I/O from a daughtercard into one 0.100-inch strip rather than multiple narrower connectors.
Can TSM-142-04-FM-DV-P-TR handle both power and signal pins simultaneously in the DV configuration?
Yes. The DV (dual-voltage) configuration in TSM-142-04-FM-DV-P-TR separates the 84-position body into two independent voltage planes within the connector housing. This allows designers to assign one group of pins to a 5 V power rail and another group to a 3.3 V or 1.8 V rail, routing both through one connector. Individual contacts in the TSM series support up to 3 A per pin, derated to approximately 1.5 A under full simultaneous loading of all pins.
What is the assembly advantage of buying TSM-142-04-FM-DV-P-TR in tape-and-reel (TR) format?
Tape-and-reel (TR) packaging feeds the 84-position connector into standard SMT pick-and-place machines in continuous reels, eliminating manual placement for each unit. This reduces per-board assembly time, improves placement accuracy to within 0.05 mm on the 2.54 mm pitch pads, and lowers defect rates in high-volume production. For factories assembling thousands of backplane boards per week, TR format is essential for maintaining line throughput and minimizing solder paste bridging defects on the dual-row footprint.
Which mating connectors are compatible with TSM-142-04-FM-DV-P-TR?
The TSM-142-04-FM-DV-P-TR mates with SAMTEC SFM, SSW, TSW, or TFW series socket strips at 0.100-inch (2.54 mm) pitch in the dual-row 42-per-row (84-position) format. Compatible socket families include SFM-142-xx-x-D and SSW-142-xx-x-D variants with matching 2×42 pin count. Board-to-board stack heights from approximately 7 mm to 20 mm are available depending on the chosen mating header, suitable for different module clearance requirements in backplane and stacked PCB configurations.
