  • ✓Datasheet: XINGLIGHT's own PDF (https://www.xinglight.cn/uploadfile/202602/29b3fea0daeeafa.pdf, linked from https://www.xinglight.cn/index.php?c=show&id=1171) is byte-identical to the copy the page carried (sha256 dded62bb4abd4913); 14 pages, no revision printed, PDF dated 2025-11-04; provenance moved from the LCSC/JLCPCB URL to the maker's
  • ✓Pins: polarity diagram (p.7) labels (1) minus and (2) plus; the bottom view puts the green cathode mark at terminal (1); pin 1 K / pin 2 A, both passive, as the symbol and footprint (cathode on pad 1); descriptions re-cited to p.7
  • ✓Footprint pads vs the Recommended Soldering Pattern (p.7): 0.77 x 0.95 mm at x = +/-0.815 (0.86 gap), exactly as printed; pad 1 (cathode) at -x
  • ✓3D model rebuilt (tier 3): the previous model, extracted from a board STEP with no licence, stood the LED upright (1.70 x 0.60 x 1.10 tall). XINGLIGHT publishes no STEP (product page links the PDF only); KiCad has no XL-1606 model (LED_Kingbright_APA1606 horizontal is a single fused solid without terminals; KiCad's chip_convex generator draws a 0.9 mm lens vs the printed 1.2). Hand-built in CadQuery from p.7, CC-BY-SA-4.0
  • ✓3D body vs p.7 at drawing scale (overlay docs/proof/xl-1606-3d-vs-drawing.png): L 1.70, W 0.60, H 1.10, base 0.48, lens top 1.20 (flank 1.27 at the base, R 0.08 measured), terminals 0.40 on the bottom and 0.15 on the top, cathode mark 0.10-0.30 mm toward pin 1; all on the drawing lines
  • ✓Mounted pose: on its side, seated on z = 0, height 0.60; lens 0.60 mm past the pads (lens tip footprint y -1.07, base y -0.45..+0.03) as the Recommended Soldering Pattern places it; terminal K over pad 1, A over pad 2
  • •Which face lies down, from the tape drawing (p.8): cathode toward the sprocket holes (reel note, diode symbol, A-A section) and lens toward the feed direction, so with the lens up the page the cathode is on the left: lens toward footprint -y. Conflict recorded: the p.7 pattern's outline is the front view pasted in and shows the green mark right of centre; it fixes position, not the face (docs/proof/xl-1606-tape-orientation.png). The bosch-ovhd-xarm_v1.0 LEDs then point at the board edge
  • ✓Footprint courtyard enlarged to -1.45..1.45 x -1.32..0.73 (0.25 mm around pads and lens; the old one ended at y -0.80, inside the lens) and F.Fab redrawn as the side-mounted body; pads, mask, paste, silk unchanged
  • •MPN etched as a virtual mark on the white base of the up-facing side wall (adom-chip-laser 0.2.0 inlay; `etch surface=side` finds no wall that fits the text and `surface=top` lands on the lens)
  • ✓DigiKey 5962-XL-1606UYCTR-ND (XINGLIGHT XL-1606UYC) confirmed by search 2026-10-28; Mouser does not carry it (searched XL-1606UYC)
  • ✓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 except pose: step_pose 0.2.0 off-origin from its contact heuristic (a 0.5 mm pad grow sweeps the body and lens into the contact on a 1.7 mm part); restricted to the terminal solids the contacts sit inside pads 1 and 2 (provenance/contact-proof.json)

XL-1606UYC

XINGLIGHT · LED Indication - Discrete · SMD,1.7x1.1mm

XL-1606UYC from XINGLIGHT, in a SMD,1.7x1.1mm. Symbol and footprint pads are the ones used on Adom board designs. The 3D model is built from XINGLIGHT's drawings and lies on its side as the datasheet mounts it: the lens points along the board toward footprint -y, 0.60 mm past the pads.

Pinout

Pin Name Type Function
1 K passive Cathode (-): terminal (1) in the polarity diagram and the bottom view, the end with the green cathode mark. [datasheet p.7]
2 A passive Anode (+): terminal (2) in the polarity diagram and the bottom view. [datasheet p.7]

CAD

  • Symbol: xl-1606uyc (source library Device:LED)
  • Footprint: LED_CDT:SIDELED_XINGLIGHT_XL-1606_1.7x1.1mm
  • 3D model path in footprint: ${KIPRJMOD}/xl-1606uyc.step
  • 3D files: xl-1606uyc-etched.step / xl-1606uyc-etched.glb carry the MPN etch as a separate Adom.LaserEtch part; xl-1606uyc.step / xl-1606uyc.glb are the bare model. The model is AI-generated (Claude, for Adom): hand-built in CadQuery from the Outline Dimension drawing (p.7) and the tape drawing (p.8), not XINGLIGHT's CAD; the etched part number is a virtual mark on the white base. Source record and builder: provenance/3d-model.json, provenance/tools/; overlay on the drawing: docs/proof/xl-1606-3d-vs-drawing.png.
  • Footprint courtyard and fabrication outline cover the side-mounted body and its lens (pads unchanged).
