What are the key features of TST-136-03-S-D?

  • 72-position dual-row shrouded header at 0.100" (2.54 mm) pitch in a 3.9 inch body, providing polarized high-density cable connections for 72-signal interfaces
  • Matte tin over nickel contact finish on both mating and termination surfaces for reliable soldering and resistance to fretting corrosion in industrial environments
  • Through-hole single-row (S) male contact pattern with rectangular layout compatible with standard 0.100" IDC and ribbon cable mating assemblies

What is TST-136-03-S-D used for?

The TST-136-03-S-D is designed for high-density cable-to-board interfaces in industrial automation, data acquisition systems, and embedded computing platforms where 72 signals must be routed through a single shrouded 2.54 mm pitch header. Its 3.9 inch body length accommodates wide ribbon cable assemblies such as 72-conductor flat cables used in legacy parallel bus architectures and programmable logic controller I/O modules. The shrouded housing also prevents mis-mating in field environments where cables are frequently disconnected for maintenance, reducing installation errors in multi-connector rack systems.

Frequently Asked Questions

What are the body dimensions of the TST-136-03-S-D and how does its size affect PCB layout planning?

The TST-136-03-S-D body measures 3.9 inches (99 mm) long by 0.365 inch wide by 0.365 inch deep. This large footprint must be allocated at the board edge or in an open PCB zone free of tall components, and designers should reserve a mating clearance zone of at least 30 mm in front of the connector face to accommodate ribbon cable bend radius and stress relief when routing 72-conductor cable assemblies.

Why is the matte tin over nickel contact finish used on TST-136-03-S-D, and what environments suit it best?

Matte tin over nickel plating on the TST-136-03-S-D provides a solderable, low-cost contact finish suitable for wave soldering or selective soldering at typical solder temperatures of 250°C to 270°C. Tin-plated connectors are preferred in cost-sensitive industrial and consumer electronics where gold plating is not required, but engineers should ensure mating contacts are also tin-finished to avoid galvanic corrosion that can increase contact resistance above 50 milliohms over time.

For a 72-signal PLC I/O expansion module, how does TST-136-03-S-D compare to using two 36-position shrouded headers?

Using a single TST-136-03-S-D consolidates all 72 connections into one keyed connector, eliminating the risk of swapping two separate 36-position connectors during field installation. The single 3.9 inch connector also reduces BOM count by one part and simplifies cable assembly tooling, requiring only one 72-conductor IDC or crimp housing versus two separate 36-conductor assemblies, which can reduce cable harness assembly cost by 15% to 25% in volume production.

What mating connectors and cable types are compatible with the TST-136-03-S-D for a complete assembly?

The TST-136-03-S-D mates with SAMTEC TSM or compatible female dual-row 0.100" (2.54 mm) pitch shrouded receptacles, as well as standard 72-conductor IDC ribbon cable connectors from multiple vendors. Ribbon cables rated for 28 AWG conductors at 300 V and 1 A per contact are typical for this pitch, with cable widths of approximately 92 mm for 72-conductor flat ribbon supporting data transfer at frequencies up to 100 MHz depending on cable quality and signal integrity requirements.
