Files

• 61204021621.kicad_mod footprint (KiCad)
• 61204021621.kicad_sym symbol (KiCad)
• 61204021621.step 3D model (STEP, Z-up, seated on z = 0, centred on the footprint origin)
• 61204021621.lbr Fusion / EAGLE library part (adom-lbr from the files above with this page's metadata; no embedded 3D, bind the STEP)

Provenance

• 61204021621.kicad_mod: KiCad Connector_IDC:IDC-Header_2x20_P2.54mm_Vertical footprint (https://gitlab.com/kicad/libraries/kicad-footprints/-/raw/master/Connector_IDC.pretty/IDC-Header_2x20_P2.54mm_Vertical.kicad_mod), unmodified except the 3D model path (now 61204021621.step). sha256/16 of the original: 547b0e374a40cdf6.
• 61204021621.step: KiCad Connector_IDC.3dshapes/IDC-Header_2x20_P2.54mm_Vertical.step (packages3D), byte-identical copy (sha256/16 b4c4f2a81aa970bd). The footprint's (model (offset 0 0 0) (rotate 0 0 0)), so the STEP is already in the footprint frame and no transform was applied. Checked with OpenCascade (step2glb features): Z-up, seated on the board plane, origin = footprint origin.

The STEP is KiCad's generic body for this package, not a manufacturer model.
• 61204021621.kicad_sym: KiCad Connector_Generic:Conn_02x20_Odd_Even (https://gitlab.com/kicad/libraries/kicad-symbols/-/raw/master/Connector_Generic.kicad_symdir/Conn_02x20_Odd_Even.kicad_sym), renamed to the MPN; pins unchanged.

Notes

• Checked against the Wurth drawing values in pins_digest.md: length 58.46 mm (KiCad body 58.46 mm), width 9.0 mm (KiCad 8.9 mm), pin 1 to pin 39 48.26 mm (KiCad 48.26 mm), recommended hole 1.1 mm (KiCad drill 1.0 mm, inside the 1.1 +/-0.15 tolerance band only at its lower limit 0.95; widen to 1.1 if the fab prefers). Key slot on the odd-pin side as in the Wurth drawing. STEP height: see the bbox in the report.
