Part Audit Review


Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
I’ll audit the part metadata, locate the official datasheet if needed, update the Datasheet property, then verify the symbol, footprint, and pin descriptions against it.

Part Audit Report Part identity and current metadata Ordering-code interpretation
  • HFD2: subminiature DIP signal relay family.
  • 003: 3 VDC nominal coil voltage.
  • No contact-material suffix: standard AgPd movable / Ag + gold-plated stationary contact combination per the ordering table.
  • S: sensitive coil.
  • L2: two-coil latching construction.
  • Contact arrangement: 2 Form C (DPDT changeover).
Key datasheet specifications Datasheet pinout and functional behavior
The datasheet shows the two-coil latching relay in the reset state:
  • Set coil: energize pin 1 relative to pin 16.
  • Reset coil: energize pin 2 relative to pin 15.
  • Pole 1 contacts: COM pin 4, NC pin 6, NO pin 8.
Audit complete. The footprint geometry and all 10 physical pin numbers match the official Hongfa datasheet; the existing Datasheet property already points to an official Hongfa page, so it was not changed.
Flagged issues: misleading coil suffixes (actual winding pairs are 1–16 set and 2–15 reset), missing pin descriptions, unspecified pin types, and overly generic package/description metadata. Full specifications and comparisons are in the Part Audit Report.
