Frequently Asked Questions
What is the contact pitch and total pin count of the TSM-127-03-TM-DH-A-K-TR, and how are pins arranged?
The TSM-127-03-TM-DH-A-K-TR features 54 positions arranged in a dual-row format with 27 pins per row on a 2.54 mm (.100") pitch, providing a compact yet high-density SMT interconnect footprint for embedded and industrial PCB designs.
How does the tall-mast termination style affect PCB cleaning and assembly processes?
The tall-mast (TM) variant raises the connector body above the PCB surface by several millimeters, creating clearance for post-reflow flux cleaning solvents to reach beneath the body; this is critical for IPC Class 3 assemblies in aerospace and defense applications where residual flux below 0.1 mg/cm2 is required.
Which mating receptacles are compatible with the TSM-127-03-TM-DH-A-K-TR for a 2.54 mm dual-row stack?
SAMTEC SSW and SSQ series female receptacles mate directly with the TSM-127-03-TM-DH-A-K-TR on the standard 2.54 mm dual-row grid; these mating connectors offer stack heights from 8.5 mm to 15 mm and are rated for over 500 mating cycles at operating temperatures from -55°C to +125°C.
