What are the key features of TST-102-03-F-D?
- 4-position dual-row shrouded header at 0.100" (2.54 mm) pitch in a compact 0.5" x 0.365" body for space-saving board-to-cable connections
- Gold flash (3 µin) over nickel mating contacts provide adequate corrosion resistance for moderate-cycle connector applications at low cost
- Shrouded polarized housing prevents mis-mating of ribbon cables and IDC assemblies across all 4 male square-pin contacts
- Tin-over-nickel termination on PCB tail ensures compatibility with standard lead-free and leaded wave or hand-soldering processes
What is TST-102-03-F-D used for?
The TST-102-03-F-D is suited for compact 4-signal board-to-cable interconnects in consumer electronics, embedded microcontroller development boards, and low-cost industrial sensor interfaces. Its tiny 0.5" shrouded body makes it ideal for tight PCB layouts where only a small number of signals need a protected cable header, such as UART, I2C, or simple power plus signal connectors. The standard 0.100" pitch compatibility allows easy pairing with common ribbon cable assemblies and IDC housings.

Frequently Asked Questions
What contact finish does the TST-102-03-F-D use on its mating contacts and how does it affect service life?
The TST-102-03-F-D uses gold flash (3 µin) over nickel on all 4 mating contacts, which provides basic oxidation resistance suitable for low-cycle applications typically under 100 mating cycles. For designs requiring frequent connector disconnection such as more than 200 cycles, a heavier gold plating variant would be preferred. The 3 µin gold flash finish is cost-effective for board-to-cable interfaces in consumer products and prototypes where connectors are mated infrequently.
For a 4-wire I2C bus connection on a sensor node PCB, what advantage does the TST-102-03-F-D offer over an unshrouded 4-pin header?
The TST-102-03-F-D's polarized shroud ensures the mating IDC or ribbon cable connector can only be inserted in the correct orientation, preventing accidental reversal of the I2C SCL and SDA lines or power and ground pins across all 4 positions at 0.100" pitch. An unshrouded header allows reversed insertion which could immediately damage the sensor IC or microcontroller. The shroud adds only a marginal cost premium while providing significant protection against costly assembly errors in the field.
How compact is the TST-102-03-F-D footprint for a dual-row 4-pin header and which embedded designs benefit from its small size?
The TST-102-03-F-D occupies a PCB footprint of 0.5" x 0.365" (12.7 mm x 9.3 mm) for its dual-row 4-position body, making it one of the most compact shrouded 4-pin headers available at 0.100" pitch. This small size suits Arduino-compatible shields, Raspberry Pi accessory boards, industrial sensor modules, and IoT gateway daughter cards where a 4-signal interface must fit in a corner of a space-limited PCB without encroaching on surrounding component clearances.
When would an engineer select the TST-102-03-F-D over a single-row 4-pin unshrouded header for a motor controller's power supply connector?
For a motor controller power supply connector carrying 2 power and 2 signal pins, the TST-102-03-F-D's dual-row shrouded design shortens the connector's 0.100" pitch board edge footprint to 0.5" compared to 0.8" for a single-row 4-pin unshrouded header. The polarized shroud prevents accidental reversal of power and ground connections that could destroy the motor driver IC, and the dual-row arrangement positions power and signal pins in separate rows, simplifying PCB trace routing to the motor driver power stage.
