Frequently Asked Questions
How many pins per row does TSM-114-04-SM-DH-A-K-TR provide, and what is the overall connector pitch?
The TSM-114-04-SM-DH-A-K-TR has 28 total positions split across 2 rows, giving 14 contacts per row at a 0.100" (2.54 mm) pitch. This standard pitch ensures broad mating connector compatibility and straightforward PCB footprint design for 28-pin parallel interfaces.
For a compact sensor-hub PCB, how much board area does the 28-position TSM-114-04-SM-DH-A-K-TR footprint occupy?
With 14 positions per row at 0.100" (2.54 mm) spacing, the mating area spans approximately 33.0 mm in length and 2.54 mm between row centerlines, for a total footprint of roughly 33 mm x 5 mm. This compact SMT area makes the connector suitable for space-constrained sensor hub PCBs with minimal board real estate.
When should designers choose the TSM-114 (28-position) over the TSM-112 (24-position) for GPIO expansion?
Designers should select the TSM-114-04-SM-DH-A-K-TR over the 24-position TSM-112 when the interface needs 25 to 28 signal lines, such as a full 16-bit data bus plus 12 control signals or a wide parallel sensor array with 28 channels. The TSM-114 adds 4 more contacts at the same 0.100" pitch, requiring only slightly more board space.
What reflow profile is compatible with the SMT pads of TSM-114-04-SM-DH-A-K-TR?
Samtec TSM series SMT connectors are specified to withstand standard lead-free reflow soldering with a peak temperature of 260°C for up to 10 seconds, conforming to IPC/JEDEC J-STD-020 moisture sensitivity requirements. The housing material retains dimensional stability through typical lead-free reflow cycles, ensuring pad alignment after soldering.
