Files

• 1817822.kicad_mod footprint (KiCad)
• 1817822.kicad_sym symbol (KiCad)
• 1817822.step 3D model (STEP, Z-up, seated on z = 0, centred on the footprint origin)
• 1817822.lbr Fusion / EAGLE library part (adom-lbr from the files above with this page's metadata; no embedded 3D, bind the STEP)

Provenance

• 1817822.kicad_mod: pads 1..4 (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 1817822 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_4-GF-3.81_1x04_P3.81mm_Horizontal_ThreadedFlange_MountHole (https://gitlab.com/kicad/libraries/kicad-footprints/-/raw/master/Connector_Phoenix_MC.pretty/PhoenixContact_MC_1,5_4-GF-3.81_1x04_P3.81mm_Horizontal_ThreadedFlange_MountHole.kicad_mod, sha256/16 0e578e7243181ad2); its two courtyard circles around the NPTH screw holes were dropped.
• 1817822.step: KiCad Connector_Phoenix_MC.3dshapes/PhoenixContact_MC_1,5_4-GF-3.81_1x04_P3.81mm_Horizontal_ThreadedFlange_MountHole.step (packages3D), byte-identical copy (sha256/16 60e280a60fb4fd7e). 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.
• 1817822.kicad_sym: KiCad Connector_Generic:Conn_01x04 (https://gitlab.com/kicad/libraries/kicad-symbols/-/raw/master/Connector_Generic.kicad_symdir/Conn_01x04.kicad_sym), renamed to the MPN; pins 1..4 unchanged. MH1 / MH2 are footprint-only pads (no symbol pin, no net).

Notes

• Mounting pads (KiCad frame): MH1 at x = -4.3, y = 0.9 mm, MH2 at x = 15.73, y = 0.9 mm. KiCad's own footprint puts its NPTH screw holes at x = -4.5 and 15.93 mm, y = 0.9 mm.
• DIFFERENCE: the EAGLE 4-pos package has MH1/MH2 at x = -4.3 / 15.73 mm (spacing 20.03 mm), 0.2 mm inboard of KiCad's -4.5 / 15.93 mm (20.43 mm), and its body outline is 0.2 mm narrower each side. The 8-pos EAGLE package matches KiCad exactly. The STEP flange holes therefore sit 0.2 mm outboard of MH1/MH2 on this part. Kept as is because the case follows the EAGLE geometry; check against the Phoenix 1817822 drawing before fabrication. The KiCad flange silk line at x = -2.41 / 13.84 mm clears the 3.6 mm MH copper by only about 0.03 mm.
