Table
| Reference | Exact entry | Official symbol/pinout specification | Official footprint/package specification | Creation status | Required follow-up |
|---|---|---|---|---|---|
| U10 | MCP41HV51-503E/ST — Microchip | TSSOP-14 pins: 1 VL (Power In), 2 CS (Input), 3 SCK (Input), 4 SDI (Input), 5 SDO (Output/Tri-State), 6 WLAT (Input), 7 SHDN (Input), 8 DGND (Ground), 9 V− (Power In), 10 P0B (Passive/Analog), 11 P0W (Passive/Analog), 12 P0A (Passive/Analog), 13 V+ (Power In), 14 NC. SPI, 50 kΩ (-503), E temperature grade. | Microchip /ST TSSOP-14, 4.4 mm body width class, 0.65 mm pitch; footprint must be generated from official Microchip package drawing in DS20005304. | NOT CREATED — PLATFORM BLOCKER | Create exact part project; verify 14 symbol terminals, pad numbering 1–14, pin-1 orientation, 0.65 mm pitch, distinct pads and TSSOP courtyard. Do not use MCP45HV proxy. |
| K1-K3 | G5LE-14-DC5 — Omron | SPDT/1c relay, five terminals. Official bottom-view mapping: pin 2 coil, pin 5 coil, pin 1 COM, pin 3 NO, pin 4 NC. 5 VDC coil approximately 79.4 mA, 63 Ω, 400 mW. Fully sealed variant (-14). | Through-hole Omron G5LE five-hole pattern from official G5LE drawing; body max approximately 22.5 × 16.5 × 19.0 mm. Hole diameter and spacing must follow official bottom-view mounting-hole drawing. | NOT CREATED — PLATFORM BLOCKER | Create exact relay symbol with named Coil/COM/NO/NC terminals; verify bottom-view pad numbering and mechanical outline. Existing proxy interpretation must not be reused without replacement. |
| L1 | MSS1246T-683MLB — Coilcraft | Non-polarized 2-terminal shielded power inductor; pins 1 and 2 passive. 68 µH ±20%; DCR 167 mΩ typ / 186 mΩ max; Isat up to 2.3/2.5/2.7 A; Irms 1.3/1.8 A. Ordering: MSS1246T series, 683=68 µH, M=±20%, L=matte-tin termination, B=less-than-full-reel packaging. | Body 12.0 × 12.0 × 4.6 mm. Official recommended land pattern: pads about 5.5 × 5.0 mm, 4.0 mm inner gap, 8.5 mm overall reference span. | NOT CREATED — PLATFORM BLOCKER | Create exact two-pin part with Coilcraft land pattern; verify body/courtyard/terminal geometry and no polarity. Current generic footprint is not acceptable. |
