Frequently Asked Questions
What pin count and pitch does TSM-127-04-TL-DH-A-P-TR provide for board interconnect routing?
TSM-127-04-TL-DH-A-P-TR is a 54-position dual-row SMT connector on a 0.100" (2.54 mm) pitch, providing 54 signal channels in a compact footprint suitable for daughter-card and backplane interconnect on standard grid PCBs.
Can TSM-127-04-TL-DH-A-P-TR be used in an automated high-speed SMT line with continuous tape feeding?
Yes. The TR suffix denotes tape and reel packaging, enabling continuous feeder loading for automated pick-and-place placement of 54-position connectors at high throughput, with standard reflow compatibility up to 260°C.
How does TSM-127-04-TL-DH-A-P-TR's gold contact plating benefit reliability in repeated mate/unmate applications?
Gold plating over the nickel barrier on all 54 mating contacts provides wear resistance across hundreds of insertion cycles and stable contact resistance below 50 mΩ even in humid or mildly corrosive industrial environments.
When should a designer choose TSM-127-04-TL-DH-A-P-TR over a TSM-131 for the same 0.100" dual-row layout?
A designer selects 54-position TSM-127-04-TL-DH-A-P-TR when the application requires fewer than the 62 pins offered by TSM-131, saving PCB area proportional to 8 fewer positions while retaining the same 0.100" pitch, gold contact finish, and tape-and-reel supply format.
