Substitute Part Grouping Explanation

Substitute parts for the SSW-125-22-S-D are identified based on strict electrical and mechanical compatibility criteria. The following parameters must remain constant for a part to qualify as a direct substitute:

  • Connector type (Receptacle)
  • Number of positions (50)
  • Pitch spacing (0.100" / 2.54mm)
  • Number of rows (2)
  • Row spacing (0.100" / 2.54mm)
  • Mounting type (Through Hole)
  • Termination method (Solder)
  • Contact finish - mating (Gold)
  • Current rating (4.7A per Contact)
  • Operating temperature range (-55°C ~ 125°C)
  • Material flammability rating (UL94 V-0)
  • RoHS compliance (ROHS3)

The SSW-125-02-S-D meets all these criteria and qualifies as a functional equivalent, despite differences in product status and moisture sensitivity level classification.

Engineering Selection Recommendations

The SSW-125-02-S-D is electrically and mechanically equivalent to the SSW-125-22-S-D. Both parts share identical connector specifications, contact ratings, and environmental compliance certifications. The primary distinction is product availability status: the SSW-125-22-S-D is currently active in production, while the SSW-125-02-S-D is discontinued at DiGi Electronics.

For new designs, the SSW-125-22-S-D is the preferred selection due to active production status and assured long-term availability. The SSW-125-02-S-D may be considered for legacy system maintenance or when existing inventory is available through alternative distribution channels, provided supply continuity can be established.

Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications.
