## Files

- `1817864.kicad_mod` footprint (KiCad)
- `1817864.kicad_sym` symbol (KiCad)
- `1817864.step` 3D model (STEP, Z-up, seated on z = 0, centred on the footprint origin)
- `1817864.lbr` Fusion / EAGLE library part (adom-lbr from the files above with this page's metadata; no embedded 3D, bind the STEP)

## Provenance

- `1817864.kicad_mod`: pads 1..8 (THT, drill 1.2 / dia 1.8 mm, 3.81 mm pitch) and the two flange mounting pads MH1 / MH2 (plated, drill 2.4 / dia 3.6 mm, no net) copied exactly from the EAGLE package `1817864` in the LEDster-TI board (`survey/LEDster-TI.brd`, sha256/16 d805b7a21df47b82), EAGLE y-up converted to KiCad y-down (y negated). The LEDster-TI case was designed around this geometry, so it was kept as is. Silkscreen, fab outline and the courtyard rectangle copied from KiCad `Connector_Phoenix_MC:PhoenixContact_MC_1,5_8-GF-3.81_1x08_P3.81mm_Horizontal_ThreadedFlange_MountHole` (https://gitlab.com/kicad/libraries/kicad-footprints/-/raw/master/Connector_Phoenix_MC.pretty/PhoenixContact_MC_1,5_8-GF-3.81_1x08_P3.81mm_Horizontal_ThreadedFlange_MountHole.kicad_mod, sha256/16 590e3239db2efac3); its two courtyard circles around the NPTH screw holes were dropped.
- `1817864.step`: KiCad `Connector_Phoenix_MC.3dshapes/PhoenixContact_MC_1,5_8-GF-3.81_1x08_P3.81mm_Horizontal_ThreadedFlange_MountHole.step` (packages3D), byte-identical copy (sha256/16 75cec8f154980cf5). The KiCad footprint and the EAGLE package both put pin 1 at the origin with the pins along +x at 3.81 mm, and the KiCad model binding has offset/rotate 0, so no transform was applied: the model sits on the pads.

The STEP is KiCad's generic model for this Phoenix series.
- `1817864.kicad_sym`: KiCad `Connector_Generic:Conn_01x08` (https://gitlab.com/kicad/libraries/kicad-symbols/-/raw/master/Connector_Generic.kicad_symdir/Conn_01x08.kicad_sym), renamed to the MPN; pins 1..8 unchanged. MH1 / MH2 are footprint-only pads (no symbol pin, no net).

## Notes

- Mounting pads (KiCad frame): MH1 at x = -4.5, y = 0.9 mm, MH2 at x = 31.17, y = 0.9 mm. KiCad's own footprint puts its NPTH screw holes at x = -4.5 and 31.17 mm, y = 0.9 mm.
