What are the key features of TSM-149-04-S-DV-P-TR?
- 98-position dual-row configuration at 0.100 inch (2.54 mm) pitch providing 49 contacts per row on the industry-standard 2.54 mm grid for broad footprint compatibility
- Dual-voltage (DV) keying designed to separate power and signal domains within the same 98-pin header, supporting multi-rail 3.3 V, 5 V, and 12 V backplane designs
- Polarized (P) mechanical key preventing incorrect 180-degree mating, protecting mixed-voltage and differential-signal circuits from reverse-connection damage
- Tape-and-reel (TR) packaging enabling automated SMT pick-and-place assembly at high production volumes with standard feeder equipment
What is TSM-149-04-S-DV-P-TR used for?
TSM-149-04-S-DV-P-TR is used in high-density backplane slots, single-board computer expansion connectors, and ATCA or VME carrier cards where a 98-position dual-row 2.54 mm pitch SMT terminal strip is needed. Its dual-voltage polarized keying is critical in multi-board systems carrying 3.3 V, 5 V, and 12 V on the same connector alongside LVDS and LVTTL signal pairs. The tape-and-reel format makes it suitable for automated production of telecom blades, industrial control backplanes, and embedded computing platforms.

Frequently Asked Questions
How many signal positions does TSM-149-04-S-DV-P-TR provide per row and what is the overall contact pitch?
TSM-149-04-S-DV-P-TR provides 98 total positions with 49 contacts per row at a 0.100 inch (2.54 mm) pitch, matching the universal 2.54 mm engineering grid used across standard backplane, Eurocard, and SBC interconnect ecosystems, ensuring off-the-shelf PCB footprint availability from multiple EDA library vendors.
What does the dual-voltage (DV) designation on TSM-149-04-S-DV-P-TR mean for a mixed power-and-signal backplane?
The DV (dual-voltage) designation indicates the connector incorporates physical keying features that separate two voltage domains within the 98-pin footprint, preventing accidental cross-connection of 5 V power pins to 3.3 V logic pins on the mating daughter card, which would otherwise cause immediate overvoltage damage to ICs in a multi-rail backplane system carrying both 5 V and 3.3 V supply rails.
Is TSM-149-04-S-DV-P-TR supplied in tape-and-reel and what automated assembly process does this support?
Yes, the TR suffix confirms tape-and-reel packaging compatible with 16 mm or wider SMT feeder tape, enabling automated pick-and-place machines to mount TSM-149-04-S-DV-P-TR at rates of 500 to 1000 placements per hour on a standard SMT line, with lead-free reflow soldering to 260°C peak meeting IPC-J-STD-020 for high-volume industrial and telecom board production.
Which mating socket from SAMTEC is recommended for TSM-149-04-S-DV-P-TR and how does the polarized key prevent mis-mating?
TSM-149-04-S-DV-P-TR mates with SAMTEC SSM or SFM series 0.100-inch dual-row socket strips; the P (polarized) suffix adds an offset or notched key in the header housing that physically blocks a 180-degree reversed socket from engaging, ensuring all 98 contacts align correctly during board-to-board mating and preventing reversal of 12 V power and 3.3 V signal pins on the backplane.
