Substitute Part Grouping Explanation

Substitution of the Molex 1001120121 is based on the following critical parameters that must align between the obsolete part and its active equivalent:

Primary Substitution Criteria:

• Connector Type: Both parts must be zSFP+ connectors to ensure mechanical and electrical compatibility
• Connector Style: Both parts must be cage-style connectors for proper module insertion and retention
• Base Product Family: Both parts share the 100112 base product number, indicating they belong to the same product line
• EMI Shielding: Both parts include EMI spring features for electromagnetic interference protection
• Manufacturer: Both parts are manufactured by Molex, ensuring consistent design standards and quality

The Molex 1001128121 meets all substitution criteria as an active product within the same 100112 series, offering direct functional equivalence with current manufacturing support and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement: The Molex 1001128121 is the designated active substitute for the obsolete 1001120121. Both parts share identical mechanical and electrical specifications within the zSFP+ cage connector category. The 1001128121 carries active product status with current manufacturing support, ensuring supply chain continuity and compliance with current export regulations (EAR99 classification).

For Legacy System Support: Existing systems utilizing the 1001120121 can transition to the 1001128121 without design modification, as both parts maintain the same connector type, cage style, and EMI shielding characteristics. The active status of the 1001128121 provides access to current quality assurance and manufacturing documentation.

Compliance Considerations: The 1001128121 is classified under ECCN EAR99, indicating standard commercial encryption status. The HTSUS code 8538.90.8180 applies to this connector category. These classifications support unrestricted procurement and distribution within standard commercial channels.
