  • ✓Datasheet: Amphenol RF customer outline drawing 925-126J-51P Rev A (03-Jun-16, ECO 00941), the file the product page https://www.amphenolrf.com/en-us/part/925-126j-51p/4449/ links today (asset 4065789372, fetched 2026-10-27, sha256 d0f7d88e2577de06). Amphenol's file is vector art with no text layer; the attached copy is that file with an invisible OCR text layer (ocrmypdf 15.2), renders pixel-identical. Replaces the page's 400 dpi raster + OCR copy
  • ✓BOM: rf-molecules rf-scaffold-module J3, J4 (BOM 'Conn_Coaxial_Small,J3/J4,925-126j-51p', footprint coax:925-126j-51p): the intended part is this page's MPN
  • ✓Pins: 1 CONTACT = centre contact, 2 BODY = body (names from the drawing's materials list; the drawing has no pin table); both passive; descriptions rewritten from the drawing, cited p.1
  • ✓Footprint rebuilt to the RECOMMENDED PCB LAYOUT, x = 0 on the board edge: Edge.Cuts slot 3.60 (3.6 +-0.05) wide x 5.03 deep (was 3.40 x 5.00, zero clearance to the 3.4 REF body); outer pads 0..8.12 from the edge, outer edges 4.92 apart, inner edges 3.60 apart over the slot and 2.08 apart from 5.03 to 8.12 (each an L of two rectangles numbered 2, so EAGLE/Fusion keep the full copper); centre pad 0.97 wide from 5.03 to 8.28 (was 5.10..8.35: every copper edge had been 0.07 further from the edge than drawn)
  • ✓3D: Amphenol RF's STP download (asset 4066964497) redirects to the myAmphenol login and the site has no redistribution licence; KiCad has no SMPM model; model built by Adom from the drawing (tier 3, CC-BY-SA-4.0, builder provenance/tools/build_925-126j-51p.py): 7.95 REF to the tab ends, contact to 8.11, 4.47 wide, z -1.40..2.11 (3.51 REF, 2.11 REF), 3.4 REF below the board with 0.32 chamfers, tabs 0.58 thick on z = 0, contact 0.71 dia on the axis 0.36 above the mounting plane; bore depth and pin tip position are not dimensioned (display assumptions, in provenance/3d-model.json)
  • ✓Pose (step_pose.py, both STEPs): Z-up, identity binding, centre 0.085 mm from the pad-pattern centre, seated on z = 0 on the pads with the body 1.40 mm below the board through the Edge.Cuts slot, as the drawing requires; MPN etched on the top flat (adom-chip-laser)
  • ✓DigiKey ARF2549-ND and Mouser 523-925-126J-51P (Amphenol RF 925-126J-51P), confirmed by part lookup 2026-10-27
  • •Boards to update (Caleb): rf-scaffold-module J3, J4 still carry the 3.40 x 5.00 slot and the 0.07 mm copper offset, and their 3D model reference is 925-169J-51PT_SMPM_Coax.step (another part)
  • ✓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

925-126J-51P

Amphenol RF · RF Coaxial Connectors (SMPM jack) · 925-126j-51p

925-126J-51P from Amphenol RF, in a 925-126j-51p. Footprint and board slot follow Amphenol RF's recommended PCB layout; the 3D model is built by Adom from the Amphenol RF drawing (CC-BY-SA-4.0).

Pinout

Pin Name Type Function
1 CONTACT passive Centre contact (BeCu, gold plated, 0.71 +-0.03 mm diameter), the RF signal; it lies on the 0.97 mm wide centre pad of the recommended PCB layout. [datasheet p.1]
2 BODY passive Connector body (brass, gold plated), the RF ground; its side tabs solder to the two outer pads of the recommended PCB layout and the part below the board sits in the 3.6 mm board slot. [datasheet p.1]

  • Symbol: 925-126j-51p (source library Connector:Conn_Coaxial_Small)
  • Footprint: 925-126j-51p, rebuilt to the RECOMMENDED PCB LAYOUT of drawing 925-126J-51P Rev A: board slot 3.60 x 5.03 mm (Edge.Cuts), outer pads 8.12 mm long from the board edge (4.92 / 3.60 / 2.08 mm), centre pad 0.97 mm wide from 5.03 to 8.28 mm. x = 0 is the board edge.
  • 3D model path in footprint: ${KIPRJMOD}/925-126j-51p.step
  • 3D files: 925-126j-51p-etched.step / 925-126j-51p-etched.glb carry the MPN etch as a separate Adom.LaserEtch part; 925-126j-51p.step / 925-126j-51p.glb are the bare model. Built by Adom from the drawing (provenance/tools/build_925-126j-51p.py; source, terms and checks in provenance/3d-model.json). The part sits in the board slot down to z = -1.40 mm, as the drawing requires.
  • EAGLE/Fusion library: 925-126j-51p.lbr (adom-lbr)
