Substitute Part Grouping Explanation

Substitution eligibility for the SMM-120-02-F-D-TR is determined by strict equivalence across the following critical parameters:

  • Connector type (Receptacle)
  • Number of positions (40)
  • Pitch and row spacing (0.079" / 2.00mm)
  • Mounting type (Surface Mount)
  • Termination method (Solder)
  • Contact finish material (Gold)
  • Current and voltage ratings (3.2A per contact, 350VAC)
  • Operating temperature range (-55°C ~ 125°C)
  • Compliance certifications (RoHS3, UL94 V-0)

The SMM-120-02-F-D-K-TR qualifies as a direct substitute based on identical values across all critical electrical and mechanical parameters. Both parts belong to the Tiger Eye™ SMM series and share the same base product number (SMM-120), confirming mechanical and electrical interchangeability.
