What are the key features of TSM-146-04-LM-DV-P-TR?

  • 92 contacts in dual-row layout on industry-standard 0.100" (2.54 mm) pitch for straightforward PCB routing and wide tool compatibility
  • LM (long machine) termination provides additional solder tail length for improved solder joint strength in high-vibration environments
  • Dual-voltage (DV) variant supports stacked or offset board configurations requiring two independent mating interfaces
  • Tape-and-reel (TR) format enables automated pick-and-place SMT assembly for high-volume production

What is TSM-146-04-LM-DV-P-TR used for?

The TSM-146-04-LM-DV-P-TR is used in high pin-count backplane, daughter-card, and board stacking applications where 92 dual-row contacts at 0.100" pitch provide a reliable, easy-to-route signal interface. It is commonly specified in industrial control systems, telecommunications equipment, and embedded server platforms that require robust, high-contact-count connections. The LM termination style makes it suitable for environments subject to mechanical vibration or thermal cycling that can stress standard-length solder joints.

Frequently Asked Questions

What is the LM termination designation on the TSM-146-04-LM-DV-P-TR, and how does it improve reliability?

LM designates a long-machine termination, meaning the solder tails are extended beyond standard length to provide greater solder joint height and fillet area. This longer termination improves mechanical retention strength — a measurable benefit in industrial or automotive applications subject to 5 G to 10 G vibration levels, where shorter solder joints may crack or cold-joint over time due to differential thermal expansion between PCB and connector.

How many signal contacts does the TSM-146-04-LM-DV-P-TR support, and what bus widths are practical?

The TSM-146-04-LM-DV-P-TR provides 92 contacts in a dual-row arrangement at 0.100" (2.54 mm) pitch, with 46 contacts per row. This contact count supports routing full 64-bit data buses with dedicated address, chip-select, and interrupt lines, or alternatively two independent 32-bit buses on separate rows — making it effective for backplane designs where multiple daughter cards must share a parallel bus infrastructure.

When is the TSM-146-04-LM-DV-P-TR preferred over a fine-pitch 0.050" alternative for the same signal count?

The TSM-146-04-LM-DV-P-TR's 0.100" (2.54 mm) pitch is preferred when signal speeds are below 100 MHz and PCB fabrication cost must be minimized, since wider pitch pads allow trace widths of 8 mil or more between contacts, reducing layer count and via requirements. In industrial backplane designs where boards may be field-replaced by technicians, the 0.100" pitch also provides physically larger contact surfaces that tolerate light misalignment during blind mating.

Is the TSM-146-04-LM-DV-P-TR suitable for high-volume automated production, and what packaging does it use?

Yes, the TSM-146-04-LM-DV-P-TR is packaged in tape-and-reel (TR) format, making it compatible with standard automated pick-and-place SMT assembly equipment. The surface mount footprint supports reflow profiles up to 260°C per IPC-J-STD-020 lead-free solder specifications. For a 92-position connector, tape-and-reel packaging significantly reduces per-unit assembly cycle time compared to manual placement from trays or tubes.
