What are the key features of TSM-144-01-SM-DV-P-TR?
- 88-position dual-row 2.54 mm pitch SMT terminal strip with selective metal (SM) plating for optimized cost and contact performance
- 3 A per contact current rating in a dual-row vertical (DV) configuration supports mixed power and signal PCB interconnects
- Tape-and-reel (TR) packaging with standard SMT footprint enables seamless integration into automated pick-and-place assembly lines
What is TSM-144-01-SM-DV-P-TR used for?
TSM-144-01-SM-DV-P-TR is used in industrial control boards, telecom equipment, and computing backplanes requiring 88-position dual-row 2.54 mm SMT terminal strips with selective plating. The SM contact finish balances electrical performance and cost, making the part attractive for mid-volume production runs in networking and embedded systems. Tape-and-reel packaging facilitates automated SMT assembly with standard reflow soldering processes.

Frequently Asked Questions
What does the SM suffix mean in TSM-144-01-SM-DV-P-TR?
The SM suffix indicates selective metal plating, where gold is applied only to the contact mating zone rather than the entire contact, reducing precious metal usage while maintaining less than 30 mΩ contact resistance. This plating strategy lowers component cost compared to fully gold-plated variants without sacrificing electrical reliability.
How many positions and rows does TSM-144-01-SM-DV-P-TR provide, and at what pitch?
TSM-144-01-SM-DV-P-TR provides 88 positions arranged in 2 rows of 44 pins each at 2.54 mm (0.100 inch) pitch, rated at 3 A per contact. This configuration suits dense signal and power routing in industrial and communications PCB designs operating up to 125°C.
For which PCB interconnect scenarios is TSM-144-01-SM-DV-P-TR a lower-cost alternative to fully gold-plated variants?
TSM-144-01-SM-DV-P-TR is an ideal lower-cost substitute for fully gold-plated 88-position 2.54 mm SMT terminal strips when mating cycles are fewer than 25 and board environments do not involve aggressive chemical exposure. Applications such as backplane daughter-card interfaces in office computing and telecom equipment are well-served by SM plating.
Is TSM-144-01-SM-DV-P-TR compatible with lead-free SMT reflow assembly?
Yes. TSM-144-01-SM-DV-P-TR meets RoHS requirements and is rated for lead-free reflow profiles peaking at 260°C, with recommended time above 217°C liquidus limited to 60 to 90 seconds to preserve contact integrity in standard 2.54 mm pitch SMT land patterns.
