  • Confirm the product category matches (e.g., don’t confuse a circuit board with a mechanical component)
  • Check dimensions and specifications
  • Verify application matches (industrial vs. consumer)

Regional Variants: Same model, different regions:

  • North American vs. European voltage requirements
  • Different certification marks (UL, CE, CSA)
  • Usually functionally identical with minor differences

Problem: Worn or Damaged Labels

When Physical Markings Are Unreadable:

Enhancement Techniques:

  • Use magnification: Jeweler’s loupe or macro photography
  • Try different lighting angles: Side lighting reveals embossed text
  • Clean surface gently: Isopropyl alcohol on cotton swab
  • Use contrast enhancement: Photo editing software

Alternative Identification Methods:

  • Examine PCB silkscreen markings (often more durable)
  • Check solder mask for etched codes
  • Look for laser-engraved serial numbers on ICs
  • Use board layout as visual fingerprint

Database Matching:

  • Upload photos to visual identification services
  • Post in technical forums with clear images
  • Contact manufacturer with board photos
  • Use connector configuration as identifying feature

Problem: Multiple Revision Versions

Determining Compatibility:

Check Revision Documentation:

  • Manufacturer websites often publish Engineering Change Notices (ECN)
  • Revision history documents detail changes between versions
  • Application notes explain compatibility between revisions

Key Compatibility Factors:

  • Pin-Compatible: Same physical connections, may work interchangeably
  • Firmware Changes: May require different software versions
  • Functional Changes: New features or removed capabilities
  • Performance Variations: Speed, accuracy, or capacity differences

Safe Substitution Rules:

  • Always prefer exact revision match
  • Newer revisions often backward compatible (but verify)
  • Older revisions rarely work in place of newer ones
  • When in doubt, contact manufacturer
