What are the key features of HTSS-121-01-T-DV-P-TR?
- 42-position single-row 0.100 inch (2.54 mm) pitch high-temperature shrouded connector rated for continuous operation up to 125°C in industrial and automotive environments
- Dual-voltage (DV) contact design supports both signal-level and moderate-power connections simultaneously within the same 42-pin connector body, reducing cable harness complexity
- Through-hole tail (T) and tape-and-reel (TR) packaging enables wave-soldering assembly and automated feeder loading for high-volume PCB production lines
What is HTSS-121-01-T-DV-P-TR used for?
The HTSS-121-01-T-DV-P-TR is designed for board-to-cable interconnects in industrial motor controllers, power conversion equipment, and automotive underhood electronics where ambient temperatures exceed 85°C. Its 42-position shrouded housing consolidates up to 42 signal and power lines into a single keyed connector, preventing miswiring during field service in harsh environments. The through-hole tail configuration provides superior mechanical retention strength compared to SMT alternatives, making it ideal for vibration-prone mounting locations in manufacturing machinery.

Frequently Asked Questions
What temperature rating does the HTSS-121-01-T-DV-P-TR carry, and which operating environments require this specification?
The HTSS-121-01-T-DV-P-TR belongs to SAMTEC's HT (high-temperature) series, rated for continuous operation at temperatures up to 125°C. This rating meets the requirements for automotive underhood applications per AEC-Q200, industrial servo drives with 85°C+ ambient inside control cabinets, and power conversion modules where internal temperatures reach 120°C during full-load operation at 40°C ambient. Standard 85°C-rated connectors in these environments would experience housing deformation and contact degradation within 500 operating hours.
Why does the dual-voltage (DV) contact design of the HTSS-121-01-T-DV-P-TR benefit mixed signal-and-power cable harnesses?
The dual-voltage (DV) configuration uses contacts rated for different current levels within the same 42-position housing, allowing engineers to route both low-level control signals (below 100 mA) and higher-power lines (up to 3 A per power contact) through a single connector. This eliminates the need for separate signal and power connectors on a board, reducing wiring harness cost by 20% to 30% and decreasing the total PCB connector footprint by at least 2 separate connector bodies.
How does the through-hole tail design of the HTSS-121-01-T-DV-P-TR provide better mechanical retention than SMT alternatives?
Through-hole tails penetrate the PCB and are soldered from the opposite side, creating a mechanical bond that withstands pull-out forces exceeding 50 N per pin — typically 5 to 10 times greater than SMT pad adhesion. For the HTSS-121-01-T-DV-P-TR with 42 pins, this translates to a connector retention force of over 2,000 N against cable pull, which is critical in vibration environments above 10 g RMS, such as those found in CNC machine spindle drives and rail vehicle electronics.
How many units are supplied per tape-and-reel of the HTSS-121-01-T-DV-P-TR, and at what production volume does reel ordering make sense?
The HTSS-121-01-T-DV-P-TR ships in tape-and-reel (TR) format on a carrier tape compatible with standard 32 mm pick-and-place feeders, with typical reel quantities of 500 units for this connector body size. Reel ordering becomes economical for production runs of 200 or more boards per month, where it reduces manual handling labor by over 40% compared to tray or cut-tape formats, and lowers per-unit connector cost by 10% to 15% versus small-quantity pricing.
