Frequently Asked Questions
How many contact positions per row does TSM-128-03-TM-DH-A-P-TR provide on its 2.54 mm pitch?
TSM-128-03-TM-DH-A-P-TR provides 56 pins in 2 rows of 28 contacts each on a 0.100 inch (2.54 mm) pitch. The dual-row body spans approximately 70 mm in length, accommodating 56 independent signal or power connections from a single surface mount connector footprint.
What does the TM suffix indicate about the mating height of TSM-128-03-TM-DH-A-P-TR compared to standard TSM variants?
The TM designation indicates a tall male variant with increased post height above the PCB surface. This provides additional mating engagement depth, typically 3 mm longer than standard-height variants, improving connector retention force and reducing the risk of partial unmating in high-vibration applications with 56-pin interfaces.
For an embedded Linux SOM carrier board needing 50+ GPIO lines, how does TSM-128-03-TM-DH-A-P-TR compare to a 40-position header?
TSM-128-03-TM-DH-A-P-TR offers 56 pins versus 40 pins, providing 16 additional contacts for supplementary GPIO, power, or ground returns on a 2.54 mm pitch. This extra capacity allows designers to break out SPI, I2C, UART, and 40+ GPIO lines through a single connector rather than using 2 separate 40-pin headers.
What are the RoHS and lead-free compliance attributes of TSM-128-03-TM-DH-A-P-TR for export-controlled procurement?
TSM-128-03-TM-DH-A-P-TR is RoHS compliant and Pb-free, meeting EU RoHS Directive 2011/65/EU requirements. Its lead-free finish makes it compatible with reflow solder profiles peaking at 260°C and suitable for procurement into European, Chinese, and Japanese markets with strict hazardous substance restrictions.
