Frequently Asked Questions
How many signal contacts does TSM-128-04-L-DH-A-P-TR provide and how does the dual-row arrangement benefit PCB layout?
TSM-128-04-L-DH-A-P-TR provides 56 signal contacts in a dual-row configuration at 0.100" (2.54 mm) pitch. Splitting 56 positions across 2 rows reduces the connector's length to approximately 2.8 inches, freeing PCB edge space compared to a single-row 56-pin alternative of roughly twice that length.
What does the L-lead style on TSM-128-04-L-DH-A-P-TR mean for PCB assembly and mating connector orientation?
The L-lead style on TSM-128-04-L-DH-A-P-TR means the solder tails are formed at a 90-degree angle relative to the contact axis, enabling horizontal or right-angle mating. This is useful in designs where the mating connector approaches from the side rather than perpendicularly, saving up to several millimeters of vertical board clearance.
Is TSM-128-04-L-DH-A-P-TR appropriate for industrial applications requiring a wide operating temperature range?
Yes. SAMTEC TSM series connectors are rated for operating temperatures from -55°C to 125°C, making TSM-128-04-L-DH-A-P-TR appropriate for industrial applications that experience thermal cycling, elevated temperatures in enclosed enclosures, or low-temperature environments common in outdoor equipment.
How does procuring TSM-128-04-L-DH-A-P-TR in tape-and-reel format affect minimum order quantities versus cut tape?
Tape-and-reel (TR) format for TSM-128-04-L-DH-A-P-TR typically requires purchasing full reel quantities, which can range from 100 to 500 pieces depending on the distributor. Cut tape options may be available for smaller quantities, though they often carry a surcharge and may have longer lead times compared to stocked reel inventory.
