What are the key features of TST-113-04-L-D?

  • 26 contacts (13 positions dual-row) at 0.100" (2.54 mm) pitch for mid-density board-to-board or IDC ribbon cable interfaces
  • Low-profile (L) contact finish option balancing cost and reliability for high-volume industrial and commercial applications
  • Full polarized shroud mechanically preventing incorrect mating and protecting pins during automated ribbon cable assembly

What is TST-113-04-L-D used for?

The TST-113-04-L-D is designed for 26-signal interface connections in embedded controllers, industrial field devices, and development boards where a standard IDC ribbon cable harness is required. Its dual-row 0.100" pitch layout is compatible with 26-pin ribbon cable assemblies widely used in legacy parallel port and GPIO expansion interfaces. The shrouded polarized header protects contacts during high-cycle board swap maintenance in PLC racks, test fixtures, and modular electronic assemblies.

Frequently Asked Questions

Can the TST-113-04-L-D serve as a drop-in replacement for a standard 26-pin IDC shrouded header in an existing PCB design?

Yes, the TST-113-04-L-D follows the standard 26-pin dual-row 0.100" (2.54 mm) pitch shrouded header footprint, making it dimensionally compatible with most existing PCB layouts using through-hole IDC headers. The shroud polarization key aligns with standard 26-conductor ribbon cable IDC socket connectors, ensuring plug-and-play replacement without PCB redesign. Designers should verify the 0.365 inch body depth clearance and confirm through-hole pin length matches their board thickness.

What current and voltage ratings apply to the TST-113-04-L-D for mixed signal and power distribution on a 26-pin bus?

SAMTEC TST series shrouded headers are rated for up to 3 A per pin at room temperature and a maximum operating voltage of 250 V AC/DC for individual contacts. For mixed-use 26-pin buses combining 3.3 V or 5 V logic signals with low-power 12 V supply rails, the per-pin current limit constrains total power distribution to approximately 36 W across dedicated power pins, sufficient for auxiliary power supply to small daughter cards drawing under 30 W.

How many mating cycles is the TST-113-04-L-D rated for, and does the tin finish limit reuse in field-serviceable equipment?

The TST-113-04-L-D with tin (L) contact finish is rated for a minimum of 30 mating cycles, which is adequate for equipment that is serviced annually over a 20- to 30-year lifecycle. For applications requiring 250 or more cycles, such as frequently reconfigured test jigs or hot-swap modules, SAMTEC offers the same TST-113 body with gold (G) contact finish, extending cycle life to 500 or more cycles while maintaining contact resistance below 20 mΩ throughout.
