Frequently Asked Questions
Does the polarized design of TSM-127-03-TM-DH-P-TR prevent mis-mating in field-serviced equipment?
Yes. The TSM-127-03-TM-DH-P-TR includes polarization (P suffix) that physically prevents inserting the mating connector in the wrong orientation. For field-serviced 54-position dual-row assemblies, this reduces the risk of damage to 54 contacts and associated PCB circuitry during maintenance or module replacement.
How does the 0.100 inch pitch on TSM-127-03-TM-DH-P-TR affect mating connector sourcing flexibility compared to finer-pitch alternatives?
The standard 0.100 inch (2.54 mm) pitch of TSM-127-03-TM-DH-P-TR means it mates with the largest family of compatible connectors available from multiple manufacturers. Unlike 0.050 inch pitch parts, this standard spacing provides broad second-source options and avoids proprietary mating constraints, simplifying procurement for 54-position board-to-board applications.
Can TSM-127-03-TM-DH-P-TR be used in automated high-volume SMT production, and what packaging does it ship in?
Yes. TSM-127-03-TM-DH-P-TR ships in tape-and-reel (TR suffix) packaging, which is compatible with automated pick-and-place equipment. The surface-mount termination style allows the 54-position connector to be placed and reflowed in standard SMT production lines without manual insertion, supporting high-volume assembly throughput.
What dual-height clearance does TSM-127-03-TM-DH-P-TR provide for stacked PCB assemblies?
The DH (dual-height) suffix on TSM-127-03-TM-DH-P-TR indicates the connector body includes an elevated profile above the PCB surface, providing mechanical clearance for the mating connector in stacked board assemblies. This dual-height design accommodates a defined board-to-board standoff distance, preventing contact interference in multi-board systems while maintaining the 0.100 inch pitch across 54 positions.
