What are the key features of TSM-143-04-G-DV-P-TR?
- 86-position dual-row SMT layout at 0.100" (2.54 mm) pitch with gold-plated (-G) contacts for lowest contact resistance and long-term corrosion protection
- Polarization (-P) key prevents 180-degree mis-insertion on an 86-contact interface, protecting all signal lines from reversal damage during assembly or field service
- Tape-and-reel (-TR) packaging ensures compatibility with automated pick-and-place lines and supports high-volume SMT production without manual handling
What is TSM-143-04-G-DV-P-TR used for?
The TSM-143-04-G-DV-P-TR is designed for high-density SMT backplane connectors, FPGA I/O expansion headers, and industrial signal bus interfaces requiring 86 reliable signal paths with low contact resistance. Its gold-plated contacts make it appropriate for low-level analog signals, high-speed digital buses, and applications where contact oxidation over years of service would degrade signal integrity. The 0.100" pitch and dual-row layout are compatible with standard PCB footprint libraries, reducing design time in industrial automation and embedded computing projects.

Frequently Asked Questions
What benefit does the gold-plated (-G) contact finish provide on TSM-143-04-G-DV-P-TR versus a tin-plated alternative?
Gold plating maintains contact resistance below 20 mOhm over the lifetime of the connector, even after years of exposure to humidity and industrial atmospheric contaminants that cause tin contacts to oxidize and increase resistance. For 86-position connectors carrying low-level analog sensor signals or high-speed LVDS pairs, this stable low-resistance interface prevents signal degradation that would require re-termination or board replacement in field-deployed equipment.
Can the TSM-143-04-G-DV-P-TR be used as a pin-for-pin substitute for TSM-143-05-TM-DV-P-TR in the same PCB layout?
Both parts share the same 86-position dual-row 0.100" pitch footprint and polarization key, so the contact and polarization pads are compatible. The key difference is that TSM-143-04-G uses a standard SMT-only mounting while TSM-143-05-TM adds through-hole retention tabs. If the PCB was designed for the -TM variant's tab holes, switching to TSM-143-04-G leaves those holes empty but does not break electrical function, though pull-out strength drops from over 50 N to the SMT solder joint limit.
How does tape-and-reel packaging on TSM-143-04-G-DV-P-TR affect minimum order quantity and per-unit cost for a 10,000-piece production build?
Tape-and-reel format for 86-position connectors typically sets the minimum reel quantity at 250 to 500 pieces, and for a 10,000-piece build the continuous reel feed eliminates manual tray handling, reducing placement cycle time by up to 30%. Per-unit cost at 10,000 pieces is generally 10% to 15% lower than tray-packaged equivalents because reel inventory commands volume pricing tiers and reduces line changeover downtime.
