Frequently Asked Questions
How does the T-style termination in TSM-128-03-T-DH-A-P-TR differ from other termination variants in the TSM-128 series?
The T suffix in the TSM-128-03-T-DH-A-P-TR indicates a specific low-profile surface mount termination style that minimizes the connector height above the PCB. Compared to standard or raised termination variants, the T-style reduces the overall stack height in board-to-board assemblies, which is advantageous for thin embedded modules requiring 56-position interfaces at 0.100 inch pitch.
What assembly and packaging benefits does the TR suffix provide for TSM-128-03-T-DH-A-P-TR production orders?
The TR suffix specifies tape-and-reel packaging, allowing the 56-position connector to be loaded directly into automated pick-and-place machines. This eliminates manual component handling, maintains accurate part orientation for the dual-row 0.100 inch pitch footprint, and supports consistent reflow soldering at typical SMT peak temperatures near 260°C across high-volume production batches.
For an embedded computing backplane with 50+ signal lines, how does TSM-128-03-T-DH-A-P-TR consolidate board-to-board routing?
TSM-128-03-T-DH-A-P-TR provides 56 positions in a single dual-row SMT connector at 0.100 inch pitch, allowing all 50 or more signals to be consolidated on one mating interface rather than splitting across multiple smaller connectors. This simplifies PCB routing, reduces connector-to-connector alignment complexity, and lowers bill-of-materials count for embedded computing and industrial backplane designs.
What are the RoHS compliance characteristics of TSM-128-03-T-DH-A-P-TR for global distribution?
SAMTEC TSM-series connectors including TSM-128-03-T-DH-A-P-TR use RoHS-compliant, lead-free materials with tin-based termination finishes. These are compatible with lead-free reflow soldering processes peaking around 260°C as required by EU RoHS 2 and China RoHS regulations, making the connector suitable for electronics destined for European, Asian, and North American regulated markets.
