Frequently Asked Questions
How many positions and rows does the TSM-120-02-STL-DH-A-K-TR provide?
The TSM-120-02-STL-DH-A-K-TR offers 40 positions arranged in 2 rows at 0.100-inch (2.54 mm) pitch, providing a total of 40 individual contact pins in a dual-row configuration. This high contact density in a single SMD component simplifies routing compared to using multiple smaller connectors across the PCB.
What does the dual-height (-DH) feature mean for mating connector compatibility?
The dual-height (-DH) designation indicates the shroud extends to provide additional guidance and contact protection above the standard housing height. This allows mating connectors to engage fully before electrical contact is made, reducing the risk of pin damage during insertion across all 40 positions and improving reliability in repeated connect-disconnect applications exceeding 100 mating cycles.
Can the TSM-120-02-STL-DH-A-K-TR be used on automated SMD assembly lines?
Yes, the -TR suffix specifies tape-and-reel packaging, which is fully compatible with automated SMD pick-and-place equipment. The component withstands standard 260°C peak reflow soldering profiles. This makes it appropriate for high-volume PCB manufacturing environments where manual handling of 40-position connectors would introduce assembly errors and slow throughput.
What SAMTEC alternatives exist for designers needing fewer positions at the same 2.54 mm pitch?
Designers can choose from the SAMTEC TSM series in smaller position counts such as TSM-110-02 (20 positions) or TSM-105-02 (10 positions) at the same 0.100-inch (2.54 mm) pitch. For through-hole mounting instead of SMD, the TSW or MW series at 2.54 mm pitch offer equivalent electrical performance with different mechanical retention suited to high-vibration environments.
