Frequently Asked Questions
How many signal positions does the TSM-127-04-LM-DH-P-TR provide and how are they arranged?
The TSM-127-04-LM-DH-P-TR provides 54 positions arranged in a dual-row configuration with 27 pins per row, using a standard 0.100 inch (2.54 mm) pitch, making it suitable for high-density signal interconnection on surface mount PCBs.
What PCB assembly process is the TSM-127-04-LM-DH-P-TR designed for, and how does its packaging support high-volume production?
This connector is designed for surface mount technology (SMT) assembly and is supplied in tape-and-reel (TR) packaging, enabling automated pick-and-place placement at high volumes. The 0.100 inch pitch and SMT termination are compatible with standard reflow soldering processes used in industrial electronics production.
Which SAMTEC mating connectors are compatible with the TSM-127-04-LM-DH-P-TR for board-to-board stacking?
The TSM-127-04-LM-DH-P-TR follows SAMTEC's standard 0.100 inch (2.54 mm) dual-row terminal strip footprint, and is compatible with SAMTEC TSM-series and corresponding header connectors designed for 54-pin mating. Confirm mating height and stack-up with SAMTEC's series selection guide before finalizing your PCB layout.
What are the key reliability features of the TSM-127-04-LM-DH-P-TR that make it suitable for industrial environments?
The TSM-127-04-LM-DH-P-TR features gold-plated contacts that provide low contact resistance and protection against oxidation, supporting long-term reliability in industrial environments with humidity or mild contamination. The SMT mounting ensures robust solder joint integrity across 54 positions for vibration-prone applications.
When evaluating lifecycle and procurement risk for the TSM-127-04-LM-DH-P-TR, what factors should buyers consider?
Buyers should verify the active lifecycle status of TSM-127-04-LM-DH-P-TR with SAMTEC, as connector series can be updated or discontinued. The tape-and-reel format supports MOQ-efficient purchasing for production runs, and stocking 54-position dual-row SMT connectors at 0.100 inch pitch from authorized distributors reduces lead-time risk for multi-board assemblies.
