Frequently Asked Questions
How many positions per row does the TST-103-04-L-D dual-row shrouded header provide?
The TST-103-04-L-D provides 6 total positions in a dual-row configuration with 3 contacts per row at 0.100" (2.54 mm) pitch. This makes it a straightforward choice for 6-wire cable assemblies such as JTAG debug headers, encoder interfaces, and SPI or I2C expansion connectors on compact embedded PCB designs.
For which low-pin-count embedded applications is the TST-103-04-L-D particularly well suited?
The TST-103-04-L-D is an excellent fit for JTAG/SWD debug headers (typically 6 to 10 pins), SPI and I2C sensor board connectors, and motor encoder feedback cables operating on 3.3 V or 5 V logic. Its small 6-position footprint and shrouded body reduce PCB space while ensuring proper polarization in hand-assembled or field-serviced boards.
What advantage does the through-hole mount of the TST-103-04-L-D offer over surface-mount alternatives for cable-attached connectors?
Through-hole mounting on the TST-103-04-L-D anchors the 6-pin connector into the PCB with solder fillets on both sides of the board, providing superior resistance to cable pull-out forces versus SMD pads that rely solely on surface adhesion. This mechanical strength is critical in cable-attached applications where repeated plug/unplug cycles or lateral cable movement can otherwise lift SMD connector pads from 1 oz copper PCB traces.
