Substitute Part Grouping Explanation

Substitution eligibility for the MMS-112-02-L-DV-M-TR is determined by strict alignment of the following parameters:

  • Connector type (Receptacle)
  • Position count (24 positions)
  • Mating pitch (0.079" / 2.00mm)
  • Row configuration (2 rows with 0.079" spacing)
  • Mounting method (Surface Mount)
  • Contact finish specification (Gold mating surface)
  • Current rating (3.9A per contact minimum)
  • Operating temperature range (-55°C ~ 125°C)
  • Compliance certifications (RoHS3, MSL 1)

The substitute part MMS-112-02-L-DV-K-TR meets all these criteria, differing only in post termination finish designation while maintaining identical mating interface characteristics and electrical performance.
