What are the key features of TST-102-05-F-D?
- Shrouded polarized housing prevents incorrect mating orientation, reducing field wiring errors in cable assembly
- Standard 0.100" (2.54 mm) pitch is compatible with the widest range of mating female sockets, ribbon cables, and IDC connectors
- 4-position dual-row layout provides 4 contacts in a compact through-hole or SMT PCB footprint suitable for power and signal connections
- Samtec TST series construction delivers reliable contact retention across commercial and industrial temperature ranges
What is TST-102-05-F-D used for?
The TST-102-05-F-D is a general-purpose shrouded PCB header used for low-density board-to-cable and board-to-board connections in consumer electronics, industrial control panels, and prototyping platforms. Its 4-pin dual-row, 0.100-inch pitch layout accommodates standard ribbon cable assemblies and IDC termination tools available from multiple suppliers. The polarized shroud makes it especially useful in production environments where connectors must be assembled correctly by technicians without additional alignment fixtures.

Frequently Asked Questions
How many contacts does TST-102-05-F-D have, and what pitch separates them?
The TST-102-05-F-D is a 4-position connector arranged in a dual-row configuration with a 0.100-inch (2.54 mm) pitch between contacts. This standard pitch is compatible with the vast majority of 2.54 mm female sockets, IDC crimp connectors, and ribbon cables commonly used in prototyping and production wiring harnesses, minimizing sourcing restrictions for mating parts.
Why does the shrouded housing of TST-102-05-F-D reduce assembly errors compared to an unshrouded header?
The shrouded housing of TST-102-05-F-D physically guides the mating connector into the correct position and prevents insertion at 180 degrees, which is the most common miswiring error on 4-pin headers. In production environments where technicians assemble dozens of cable harnesses per hour, this polarization reduces defect rates and avoids damage to downstream circuitry that would result from reversing a power or signal connection.
For a 5 V logic board-to-cable connection, how does TST-102-05-F-D compare to a bare 2.54 mm pin header?
Unlike a bare pin header, TST-102-05-F-D includes a shrouded housing that provides mechanical keying at 0.100-inch pitch, protecting the 4 pins from accidental bending during cable assembly. The shroud also adds strain-relief support to the mating connector, improving long-term contact reliability in systems subject to vibration or repeated cable removal, such as 5 V powered industrial sensors or field-service equipment.
What standard ribbon cable or IDC tooling is compatible with TST-102-05-F-D?
TST-102-05-F-D accepts standard 4-circuit, 2.54 mm pitch IDC ribbon cable assemblies that terminate with female sockets such as Samtec FFSD or equivalent 0.100-inch IDC connectors. This compatibility means the connector can be used directly with 28 AWG flat ribbon cables and hand-operated or bench IDC press tools rated for 2.54 mm pitch, which are widely available from multiple suppliers at low cost.
