Frequently Asked Questions
How many positions and at what pitch does the TSM-127-02-T-DH-P-TR terminal strip offer?
The TSM-127-02-T-DH-P-TR provides 54 positions arranged in a dual-row surface mount configuration at 2.54 mm (0.100 inch) pitch. This makes it one of the higher-density options in the SAMTEC TSM series for applications needing a large number of signal contacts in a standard SMT footprint.
For a backplane or modular computing design, how does the dual-in-line horizontal orientation of TSM-127-02-T-DH-P-TR affect PCB layout?
The dual-in-line horizontal (DH) orientation of the TSM-127-02-T-DH-P-TR routes the 54 pins in two parallel rows along the board edge or mid-board area, which simplifies trace routing on multilayer PCBs for backplane and computing module designs that require organized signal grouping at 2.54 mm pitch.
When should a designer choose the 54-position TSM-127-02-T-DH-P-TR over a lower pin-count SAMTEC terminal strip?
A designer should select the TSM-127-02-T-DH-P-TR when the interface requires 54 or more signal, power, or ground contacts at 2.54 mm pitch in a single SMT connector. This avoids cascading multiple lower-count connectors and reduces assembly steps, particularly when the tape-and-reel format is needed for automated placement.
What compliance and traceability information should procurement verify for the TSM-127-02-T-DH-P-TR before qualification?
Procurement should verify RoHS and REACH compliance status, confirm lead-free (Pb-free) contact plating specifications, and request the current lifecycle status for the TSM-127-02-T-DH-P-TR. Checking SAMTEC's official documentation for this 54-position, 2.54 mm pitch connector ensures alignment with environmental and quality standards required for production qualification.
