Frequently Asked Questions
How does the kinked tail (K) contact feature in TSM-129-03-TM-DH-A-K-TR improve solder joint reliability?
The kinked tail contact design in the TSM-129-03-TM-DH-A-K-TR increases the solder contact surface area and introduces a controlled mechanical compliance for each of the 58 positions. This reduces stress concentration at the solder joint during thermal cycling between -40°C and elevated operating temperatures, improving fatigue resistance and long-term solder joint integrity in SMT assemblies.
What is the total pin count and row arrangement of the TSM-129-03-TM-DH-A-K-TR, and how does it compare to smaller TSM-series alternatives?
The TSM-129-03-TM-DH-A-K-TR provides 58 positions arranged in 2 rows of 29 contacts each at a 0.100 inch (2.54 mm) pitch. Compared to lower-position TSM variants such as 48-position or 54-position models, this part is selected when the design requires more signal lines in a single dual-row connector without increasing the connector pitch or moving to a second connector.
For a telecom line card design, is the TSM-129-03-TM-DH-A-K-TR suitable for high-cycle mating, and what mating connector is required?
The TSM-129-03-TM-DH-A-K-TR is designed for standard board-to-board interconnection and mates with corresponding SAMTEC male header strips at 0.100 inch pitch in a 58-position dual-row layout. For telecom line card applications requiring frequent mating cycles, designers should verify the rated mating cycles in SAMTEC's datasheet and confirm that the mating header's 58-pin footprint is compatible with the PCB layout and stack height requirements.
What are the key procurement considerations when ordering TSM-129-03-TM-DH-A-K-TR in volume, including lead times and packaging format?
The TSM-129-03-TM-DH-A-K-TR is supplied in tape-and-reel (TR) format, supporting high-volume automated SMT assembly for production quantities. Buyers should expect SAMTEC's typical factory lead times of 8 to 12 weeks for standard orders, and should place purchase orders with authorized distributors well ahead of scheduled production starts to avoid line stoppages on 58-position dual-row SMT connector supply.
Is the TSM-129-03-TM-DH-A-K-TR compliant with RoHS and lead-free assembly processes?
SAMTEC's TSM-series connectors, including the TSM-129-03-TM-DH-A-K-TR, are manufactured to be compatible with lead-free (RoHS-compliant) soldering processes, supporting reflow temperatures of up to 260°C. Buyers specifying this 58-position SMT connector for RoHS-compliant assemblies should confirm the specific RoHS compliance documentation from SAMTEC or an authorized distributor prior to qualification.
