Frequently Asked Questions
How many signal pins does TSM-127-04-STL-DH-A-P-TR provide and at what pitch for high-density PCB use?
The TSM-127-04-STL-DH-A-P-TR offers 54 positions in a dual-row arrangement at 0.100 inch (2.54 mm) pitch, providing enough signal capacity for parallel data buses, mixed-signal interfaces, or multi-axis motor control wiring on a single standard-grid footprint.
What does the STL (shrouded through-hole locking) feature add to TSM-127-04-STL-DH-A-P-TR in an assembly context?
The STL designation adds a shrouded housing with through-hole locking posts, giving the 54-position connector mechanical retention in both the vertical and lateral directions during soldering and mating, which is important for vibration-prone industrial or automotive electronic assemblies.
For an FPGA carrier board requiring 54 I/O signals, how does TSM-127-04-STL-DH-A-P-TR fit into the design?
With 54 positions at 2.54 mm pitch in a dual-row SMT format, TSM-127-04-STL-DH-A-P-TR routes all 54 FPGA I/O pins through a single connector footprint, reducing PCB routing complexity and saving board space compared to using two separate 27-position single-row strips.
Is TSM-127-04-STL-DH-A-P-TR compatible with automated SMT assembly and what packaging is it available in?
Yes, the TR suffix confirms tape and reel packaging compatible with standard pick-and-place equipment, and the SMT termination supports automated reflow soldering processes. Standard reel quantities typically start at 500 units for this 54-position dual-row connector.
