Frequently Asked Questions
What is the pin count and row arrangement of the TST-102-04-L-D PCB header?
The TST-102-04-L-D is a 4-position dual-row shrouded PCB header with 0.100" (2.54 mm) pitch, providing 2 pins per row arranged in 2 rows. The shrouded plastic housing with keying features prevents reversed insertion, making it a reliable choice for internal power distribution, reset headers, and low-signal-count cable-to-board interfaces in PCB assemblies requiring polarized mating.
What types of mating connectors are used with the TST-102-04-L-D shrouded header?
The TST-102-04-L-D mates with SAMTEC's corresponding SSW or IDC socket connectors designed for 0.100" (2.54 mm) pitch dual-row 4-position shrouded headers. Compatible cable assemblies include crimp-style socket housings and IDC ribbon cable connectors that engage the plastic shroud walls for positive retention, achieving typical contact resistance below 20 milliohms in properly seated connections.
For a small motor controller PCB, why would an engineer choose the TST-102-04-L-D over an unshrouded header with the same 0.100" pitch?
On a motor controller PCB, the TST-102-04-L-D's shrouded housing provides keyed polarization that prevents cable mis-insertion during field servicing, reducing the risk of damage from reversed supply or signal connections. The plastic shroud also offers mechanical protection to the 4 dual-row pins against accidental contact or bending during PCB handling, which is especially valuable in vibration-prone industrial environments where connectors may be disconnected and reconnected multiple times.
What mounting style does the TST-102-04-L-D use, and how does it affect soldering during PCB assembly?
The TST-102-04-L-D uses through-hole mounting with 0.100" (2.54 mm) pitch pins that are inserted into PCB holes and wave soldered or hand soldered. Through-hole mounting provides superior pull-out strength compared to surface mount alternatives, typically exceeding 5 N per pin, which is important for cable-to-board connectors that experience mechanical stress during cable insertion and removal in the field.
