Frequently Asked Questions
How many positions does TSM-136-02-T-DH-A-K-TR offer and what pitch does the connector use?
The TSM-136-02-T-DH-A-K-TR is a 72-position dual-row terminal strip using 0.100" (2.54 mm) pitch, making it compatible with the most widely used through-hole and surface-mount spacing standard. The 72-pin count divided across 2 rows of 36 positions each allows broad signal and power distribution across one connector.
What does the dual-height (DH) feature mean for stacked PCB assemblies using this terminal strip?
The dual-height (-DH) standoff provides an elevated contact zone above the PCB surface, enabling controlled board-to-board spacing when mated with a corresponding receptacle or header. This is particularly useful in stacked mezzanine designs where 2 boards need a defined separation distance, typically several millimeters, to accommodate components mounted on the inner-facing surfaces.
How does 0.100" pitch compare to fine-pitch alternatives when selecting connectors for high-current applications?
At 0.100" (2.54 mm) pitch, each contact position occupies more PCB space than 1.27 mm or 2.00 mm pitch alternatives, but the wider spacing allows larger contact cross-sections capable of handling currents in the range of 3 A to 5 A per pin depending on the contact material and plating. For power rails requiring aggregate currents above 10 A, multiple pins at 0.100" pitch can be paralleled more easily than at tighter pitches.
Which tape-and-reel packaging spec should procurement confirm before ordering TSM-136-02-T-DH-A-K-TR at volume?
The -TR suffix confirms tape-and-reel packaging, but procurement engineers should verify the reel quantity (commonly 500 to 1000 pieces per reel for a 72-position connector of this body size) and the minimum order quantity. Large-body terminal strips may have lower per-reel quantities than smaller connectors, affecting just-in-time delivery planning for production runs.
