Schematic symbol contents
  • Symbol terminals present: 1, 2, 3, 4, 5
  • Pin Type on symbol terminals: Unspecified (all)
  • Nets: none (expected for a part symbol template)
Step 2 — Datasheet URL check and update
  • A datasheet URL is already set: PDF. No update needed.
Step 3 — Datasheet scan and metadata extraction Context: This is the Mini ISO relay accessory family; MPN 2-1904045-4 corresponds to V23333-Z0002-A041, the PCB Socket version.
General description and versions
  • Family: Connectors for Mini ISO Relays (Automotive Relays Accessories)
  • Versions described: PCB Socket; 5‑pole Connector (snap-in); 5‑pole Connector with mounting flap (interlocking/screw-on)
  • Your MPN: PCB Socket (V23333-Z0002-A041)
Functional/Features
  • Purpose: PCB‑mountable socket for Mini ISO relays with plug-in terminals; enables easy replacement and service.
  • Socket style: 5‑pole (accepts Mini ISO form factors)
Pin count and identification
  • Poles/pins: 5
  • Cavity usage (for connector variants reference):
    • Form A: cavities 1,2 (coil), 3,5 (load)
    • Form C: cavities 1,2 (coil), 3,4,5 (load)
    • Note: For the PCB socket, pin numbering physically aligns to the 5 positions; the coil/load mapping applies to the relay inserted, not to the socket’s electrical assignment by itself.
Mechanical/Package dimensions (datasheet values, mm)
  • Dimensions called out include: 1.8 ±0.1; 14.5; 2 (0/−0.1); 10 (+0.3/0); 24; 7; 26.5; 7.5; 13 ±0.1; 6.5 ±0.05; 7.5 ±0.05; 11.9; 13 ±0.1; 17.4 ±0.1; 3.2; 8 ±0.1; 8.7 ±0.1; 18.2 ±0.1; 2 ±0.1; 7.5 ±0.05; 6.5 ±0.05; 2.5
  • Weight (reference tech data): approx. 7.0 g (PCB socket)
PCB recommendations
  • PCB hole diameter (called out): 2.0 mm (tolerance 0 to −0.1 mm)
  • Associated dimension in drawings: 1.8 ±0.1 (likely terminal pin diameter basis)
  • Pitch/spacing values present in drawings: 6.5 ±0.05 mm; 7.5 ±0.05 mm; 8.0 ±0.1 mm; 8.7 ±0.1 mm; 13.0 ±0.1 mm
  • Mounting recommendation: solder with the relay already inserted to keep insertion force off the PCB.
Electrical characteristics / absolute max / operating conditions
  • Not applicable for this mechanical socket; no electrical performance tables are present in the document.
Ordering/packaging notes (for context)
  • PCB socket variant packaging example: 500 pcs (reference table)
  • Crimp terminals note applies to connector variants (not the PCB socket)
Step 4 — Cross-check of symbol and footprint against the datasheet Schematic symbol
  • Pin count: The symbol has 5 terminals (1–5), which matches the “5 pole” requirement in the datasheet. Good.
  • Pin names: The current terminals have no functional names (number-only). For a socket, numeric cavity labels are acceptable; consider adding descriptive notes in the symbol properties if you want to hint coil/load cavities for common relay forms, but do not hard-code automotive numbers (30/85/86/87/87a) unless you’re certain the mating relay and orientation are fixed.
  • Pin types: All five symbol terminals are “Unspecified.” For a passive socket, set each to “Passive” to avoid ERC ambiguity.
PCB footprint
  • Footprint source: KiCad asset “V23333Z0002A041_2.kicad_mod” is embedded in the part.
  • Electrical pads in footprint:
    • Pad 1: thru-hole, size 3.75 mm, drill 2.5 mm, at (-8.7, 0.7)
    • Pad 2: thru-hole, size 3.75 mm, drill 2.5 mm, at (0, 10.2)
    • Pad 3: thru-hole, size 3.75 mm, drill 2.5 mm, at (8.7, 0.7)
    • Pad 4: thru-hole, size 3.75 mm, drill 2.5 mm, at (0, -8)
    • Pad 5: thru-hole, size 3.75 mm, drill 2.5 mm, at (0, 0)
  • Additional holes present in footprint:
    • Pad 6: thru-hole, size 2.0 mm, drill 2.0 mm, at (6.5, -5.8)
    • Pad 7: thru-hole, size 2.0 mm, drill 2.0 mm, at (-6.5, 8.2)
    • Likely mechanical stabilizers/snap features. The datasheet’s “snap-in pin” language applies to connector variants; for the PCB socket variant, the datasheet does not explicitly state snap-in pegs. Treat these as mechanical holes unless a TE drawing for V23333-Z0002-A041 confirms they are electrical.
Footprint vs datasheet checks
  • Pad count vs pin count:
    • Symbol has 5 terminals; footprint has 7 holes (5 large + 2 small). If Pads 6 and 7 are mechanical only, they should be NPTH mechanical holes (no copper, no pad numbers) rather than plated “pads.” As currently defined (through-hole pads on copper), they will appear as electrical pins and can cause netlist mismatches. Flag: consider converting Pads 6 and 7 to NPTH/mechanical holes or add two “Mechanical/NC” pins to the symbol to keep pad/pin counts aligned.
  • Hole diameters:
    • Datasheet calls out PCB hole diameter of 2.0 mm (0/−0.1). The footprint uses 2.5 mm drills for the five main pads. This is larger than the datasheet’s stated PCB hole diameter and may compromise mechanical retention or solder fillet. Flag: verify the correct hole size for the main terminal posts on the PCB socket; adjust drills to 2.0 mm (with specified tolerance) if the datasheet dimension applies to those terminals.
    • The footprint’s smaller holes (Pads 6 and 7) use 2.0 mm drills, which align with the 2.0 mm callout, suggesting those may be the intended “mechanical” holes. If so, the five electrical posts might instead require a different drill spec; confirm with the official dimensional drawing specific to V23333-Z0002-A041.
  • Pad positions and spacing:
    • Footprint pad coordinates reflect spacings like 8.7 mm and 10.2 mm, which correlate with datasheet callouts (8.7 ±0.1, 10 +0.3/0). This looks consistent.
  • 3D model:
    • 3D STEP “2-1904045-4.stp” is attached, which is good for mechanical verification.
Actionable flags and recommendations
  • Symbol pin types: Change all five symbol terminals to “Passive.”
  • Pad/pin count alignment:
    • If Pads 6 and 7 are purely mechanical, convert them to NPTH mechanical holes (no copper, no pad numbers) to avoid netlist issues; otherwise, add two “Mechanical/NC” pins to the symbol so the pin count matches the footprint.
  • Drill sizes:
    • Reconcile the 2.5 mm drills on Pads 1–5 with the datasheet’s 2.0 mm PCB hole spec. If 2.0 mm is correct for the main terminals, reduce drills accordingly. If 2.0 mm applies only to mechanical pegs, obtain or confirm the correct drill for the terminal posts from a TE dimensional drawing specific to V23333-Z0002-A041 and update the footprint.
If you want, I can proceed to:
  • Update symbol pin types to Passive and, based on your preference, either add two mechanical pins to the symbol or convert the two extra pads to NPTH mechanical holes in the footprint.
  • Adjust drill sizes once you confirm which holes the 2.0 mm spec applies to.
