Frequently Asked Questions
How many signal lines can TSM-127-02-SM-DH-A-P-TR accommodate in a dual-row layout?
The TSM-127-02-SM-DH-A-P-TR provides 54 pins arranged in 2 rows of 27 on a 0.100 inch (2.54 mm) pitch, accommodating up to 54 discrete signal or power connections within a compact surface mount footprint suitable for high-density PCB designs.
Is TSM-127-02-SM-DH-A-P-TR compatible with standard 0.100 inch pitch mating connectors from other manufacturers?
Yes, the 0.100 inch (2.54 mm) pitch of TSM-127-02-SM-DH-A-P-TR is a widely adopted industry standard, so it mates with compatible dual-row headers from SAMTEC and many other manufacturers. Verify mating height and contact geometry against the specific mating connector before finalizing a design.
What reflow soldering profile is recommended when assembling TSM-127-02-SM-DH-A-P-TR on a high-density PCB?
SAMTEC TSM-series surface mount connectors are compatible with standard lead-free reflow profiles peaking at 260°C for up to 30 seconds. Refer to the SAMTEC TSM datasheet for exact MSL rating and bake requirements to ensure reliable solder joints across all 54 pins.
For a development board expansion interface requiring 50+ GPIOs, how does TSM-127-02-SM-DH-A-P-TR compare to a 40-position alternative?
TSM-127-02-SM-DH-A-P-TR offers 54 pins versus 40 pins in a similarly pitched connector, providing 14 additional contacts for extra GPIO, power, or ground signals on a 2.54 mm pitch grid. This makes it preferable for complex FPGA or MCU development boards where signal count exceeds 40 lines.
