SymbolFootprint3D modelPinsfor all variants

✓Datasheet: Amphenol RF customer outline drawing SMP-MSCM-PCS12T Rev A (29-JUN-20, ECN 15254), re-downloaded 2026-10-27 from the product page https://www.amphenolrf.com/en-us/part/smp-mscm-pcs12t/8523/ (asset 4067489470): sha256 c81763fffdf1773c, identical to the page's copy
✓BOM: rf-molecules coax-antennuator-molecule-32x32 J1, J2 (bottom side) and coax-molecule-2ch-64x64 J1-J4 use footprint coax:SMP_MSCM_PCS12T (BOM value Conn_Coaxial_Small, no other MPN): this part
✓Pins: 1 CONTACT = centre contact, 2 BODY = body (names from the drawing's materials list); both passive; descriptions rewritten from the drawing, cited p.1
✓Footprint pad 2: on every board placement pad 2's absolute angle minus the footprint angle is +90 deg (mirrored on B.Cu), which the page had lost (its 6.5 mm ground square sat at (-2.7, -2.7) with the slot facing -x). Redrawn as one polygon to the RECOMMENDED PCB LAYOUT: 6.5 mm square centred on the axis, 4.24 mm clearance centred on the axis, 2.73 mm slot from the clearance to the edge facing the centre pad (the board's stroke-built land gives 4.20 and 2.91)
✓Footprint pad 1: 0.63 x 2.03 mm from 2.60 to 4.63 mm from the axis per the layout (centre 3.615; the board had 3.600)
✓3D: Amphenol RF's STP download (asset 4067489468, labelled for SMP-MSCM-PCS-12) redirects to the myAmphenol login and the site has no redistribution licence; KiCad has no SMP model; model built by Adom from the drawing (tier 3, CC-BY-SA-4.0, builder provenance/tools/build_smp-mscm-pcs12t.py): base 6 REF square with corners on the 8 REF circle, body 6 REF, 4.1 REF to the interface plane plus the 0.30 PTFE cap wall (4.40 overall), cap 6.80 dia (measured), tail 0.38 REF wide ending 0.55 REF past the base, seated on z = 0. The previous model was 4.10 tall without the cap wall
✓Pose (step_pose.py, both STEPs): Z-up, seated z = 0, identity binding, centre 0.615 mm from the pad-pattern centre (the pad field includes the centre pad outside the body); MPN etched on the PTFE cap top (adom-chip-laser)
✓DigiKey 115-SMP-MSCM-PCS12TTR-ND (tape and reel, Amphenol RF SMP-MSCM-PCS12T) and Mouser 523-SMP-MSCM-PCS12T, both confirmed by search 2026-10-27
•adom-lbr drops custom-pad primitives, so the .lbr carries pad 2 as its 6.5 x 1.13 mm anchor bar only; KiCad gets the full land
•Boards to update (Caleb): coax-antennuator-molecule-32x32 J1, J2 and coax-molecule-2ch-64x64 J1-J4 keep the stroke-built ground land (4.20 clearance, 2.91 slot), pad 1 at 3.600, and scale their 3D model 1.6 x 1.6 x 1
✓Symbol Datasheet / MPN / Manufacturer / DigiKey / Mouser / LCSC properties agree with page.json; footprint Datasheet property points at the manufacturer datasheet URL
✓component-page-verify: all checks pass

reviewfor all variants

•The board footprint scales its 3D model by 1.6x; KiCad STEP export ignores model scale, so the extracted model here is the unscaled geometry. Check the body size against the Amphenol drawing.

reviewfor all variants

•The schematic writes the MPN as SMP_MSCM_PCS12T (underscores); the orderable Amphenol RF part number is SMP-MSCM-PCS12T.

SymbolFootprint3D modelPinsfor all variants

✓Footprint extracted pad-for-pad from the source board and normalized to the footprint frame (back-side parts un-mirrored)
✓3D model seated z=0 at footprint origin (placement inverse; method centroid-matched to KiCad library models on 59 cases)
✓adom-lbr generate + lint passed
✓2 of 2 pins described
•Not yet checked by a person: land pattern vs datasheet, pin-1/orientation, 3D body vs drawing
