141V 141R 2.54mm PCB Terminal Block — Vertical & Right-Angle Screw Connector
141V & 141R 2.54mm PCB Terminal Blocks — Vertical and Right-Angle Screw Connectors for Compact PCB Wiring
The 141V (vertical) and 141R (right-angle) 2.54mm PCB terminal blocks are compact screw terminal connectors at the standard 2.54mm (0.1") breadboard pitch, offering a choice of wire entry direction to suit different PCB layout requirements. The 141V (vertical) variant accepts wire from above the PCB surface, while the 141R (right-angle) variant accepts wire horizontally from the PCB edge — ideal for panel-mount designs where wires enter from the side of an enclosure. Both are rated at 150V/6A and accept 26–18AWG wire.

141V vs 141R — Choosing Wire Entry Direction
141V (vertical): Wire enters from above the PCB. Best for open PCB assemblies, benchtop equipment, and designs where the PCB is horizontal and wires drop in from above. 141R (right-angle): Wire enters horizontally from the PCB edge. Best for panel-mount designs, vertical PCBs in enclosures, and designs where wires must enter from the side. Both use the same 2.54mm PCB footprint — choose based on your enclosure and wiring direction requirements.
Ideal Applications
- Arduino and Raspberry Pi shield field-wireable connections
- Compact industrial control board I/O terminals
- Panel-mount PCB designs with side-entry wiring (141R)
- LED driver and lighting control board connections
- Home automation and IoT device PCB wiring
Frequently Asked Questions
Q: What is the difference between 141V and 141R?
A: 141V has vertical wire entry (wire enters from above the PCB). 141R has right-angle wire entry (wire enters horizontally from the PCB edge). Both use the same 2.54mm pitch PCB footprint.
Q: Are 141V/141R compatible with KF128-2.54mm footprints?
A: The PCB pin spacing is the same 2.54mm pitch, but the overall footprint dimensions may differ. Verify the specific footprint in your EDA library before substituting.
