5-Position PCB Header Replacement
USE THESE 5-pos PCB header (3.81mm): Phoenix 1803303 (MC 1,5/5-G-3,81)
And the matching plug (wire side): Phoenix 1803604. INSTEAD OF THE 6

I’ll replace the 6-position block with a 5-position 3.81 mm Phoenix header and document the mating plug.
Planned steps:
- Remove the six generic terminals; add Phoenix 1803303 (MC 1,5/5-G-3,81) as J1 and label pins 1–5.
- Note the mating plug Phoenix 1803604 in project properties and BOM notes (non-mounted).
- Sync and place the new footprint, ensuring space for routing/vias; update the project description.
Before I run it:
- Confirm the -G orientation (MC 1,5/5-G-3,81) is the exact header you want.
- Any required left-to-right pin mapping or names for pins 1–5?
- Include the plug as a DNP BOM line item, or only as a project property note?

Plan
Goal
- Replace the current 6-position Würth terminal block with a 5-position 3.81 mm Phoenix Contact PCB header (MPN 1803303) on the schematic and PCB layout, and document the mating wire-side plug (MPN 1803604) in the project BOM and description.
-
Schematic Update
- Remove the six generic 'Terminal' components that currently represent the 6-position block.
- Add the Phoenix Contact 5-position PCB header (MPN 1803303) to the schematic. Assign a clear designator (e.g., J1) to the header.
- Label the five pins in the desired left-to-right order and ensure any existing net names are preserved or reassigned as needed for proper connectivity.
-
PCB Footprint and Layout
- Remove the footprint associated with the old 6-pos terminal block from the PCB layout.
- Place the new 5-position 3.81 mm header footprint (Phoenix Contact MPN 1803303) in the layout. Ensure appropriate spacing for routing and vias according to best practices.
-
BOM and Project Documentation
- Update the project description to reflect the use of the Phoenix Contact header family and the new 5 positions.
- Add or update BOM notes to list the Phoenix header (MPN 1803303) as the PCB mounted connector and document the mating plug (MPN 1803604) as the corresponding wire-side connector.
- Set project properties or comments to note the availability and ordering details for both connectors.
- The schematic includes a single 5-position Phoenix Contact header (MPN 1803303) with designator J1, and the six old terminal symbols are removed.
- The PCB layout uses the correct footprint for the 5-position header and provides sufficient clearance for routing/vias.
- The project description and BOM notes clearly identify the new Phoenix connector and its mating plug (MPN 1803604).
