What are the key features of TSM-124-01-S-DH-P-TR?
- 48 positions in dual-row layout (24 per row) at 0.100" (2.54 mm) standard pitch
- Straight-post (S) contact style for standard SMT footprint compatibility and low-cost PCB layout
- Polarizing (P) key prevents incorrect mating orientation across 48 positions during assembly
- Dual-row high-profile (DH) housing maximizes position count within a compact connector footprint
- Tape-and-reel (TR) packaging for compatibility with automated pick-and-place SMT manufacturing
- SMT termination style enables reflow soldering in both lead-free and standard assembly processes
What is TSM-124-01-S-DH-P-TR used for?
The TSM-124-01-S-DH-P-TR is used in board-to-board and daughter-card interconnection designs in industrial programmable logic controllers, embedded computing platforms, and test instrumentation requiring 48 polarized signal connections at 0.100 inch pitch in a surface-mount dual-row connector. The straight-post contact and polarizing key combination make this part suitable for standardized module designs where interchangeable board stacking with correct orientation is a manufacturing and field-service requirement.

Frequently Asked Questions
What contact style does the TSM-124-01-S-DH-P-TR use, and how does it differ from kinked-tail variants in the same TSM series?
The TSM-124-01-S-DH-P-TR uses straight-post (S) SMT contacts, which provide a standard flat solder tail for reflow attachment across all 48 positions at 0.100 inch pitch. Kinked-tail (K) variants add a compliant bend in the solder tail to absorb thermal expansion stress, which improves solder joint fatigue life in applications exposed to wide temperature swings between -40°C and +85°C, while the straight-post version is preferred for cost and footprint simplicity in less demanding environments.
How does the polarizing (P) feature on the TSM-124-01-S-DH-P-TR support standardized module assembly?
The polarizing (P) feature on the TSM-124-01-S-DH-P-TR includes a mechanical key in the 48-position dual-row housing that forces the connector to mate only in the correct orientation. In standardized modular board designs where multiple identical modules are produced and field-replaced, this prevents 180-degree mis-insertion that would reverse all 48 signal lines and potentially damage the connected electronics.
For a 48-position SMT connector, what PCB layout area does the TSM-124-01-S-DH-P-TR require, and how should clearance be planned?
The TSM-124-01-S-DH-P-TR follows SAMTEC's standard 0.100 inch (2.54 mm) pitch dual-row footprint for 48 positions, with a total body length determined by 24 positions per row at 2.54 mm spacing. PCB designers should add at least 1.0 mm of keepout clearance on all sides of the connector footprint and verify the component height against the mated stack dimension in the SAMTEC mechanical drawing to ensure fit within the enclosure.
When is TSM-124-01-S-DH-P-TR recommended over TSM-124-03-F-DH-P-TR for a 48-position board-to-board application?
TSM-124-01-S-DH-P-TR uses straight-post (S) contacts while TSM-124-03-F-DH-P-TR uses female (F) contacts, so the two parts serve opposite sides of a mated board-to-board pair at 0.100 inch pitch and 48 positions. The straight-post variant is selected for the header side of the connection, while the female variant mates on the socket side; both include the polarizing (P) key to enforce a single valid mating orientation.
What are the supply chain considerations when sourcing TSM-124-01-S-DH-P-TR for a multi-year industrial program?
Buyers should confirm the active production status of TSM-124-01-S-DH-P-TR with SAMTEC and establish supply agreements with at least one authorized distributor to cover 24 to 36 months of projected usage. SAMTEC's standard factory lead times for SMT terminal strips can reach 10 to 12 weeks, so placing blanket purchase orders or stocking 3 months of safety inventory at 48-position dual-row level reduces the risk of production stoppages caused by connector supply gaps.
