Substitute Part Grouping Explanation
The TE Connectivity AMP Connectors 1116062-2 qualifies as a substitute based on the following critical parameters:
- Connector Configuration: Both parts are 8p8c (RJ45, Ethernet) jack connectors with identical contact count and arrangement
- Orientation: Both feature 90° right-angle (right) orientation for identical PCB mounting geometry
- Electrical Termination: Both use solder termination with phosphor bronze contacts finished in gold (50.0µin thickness)
- Shielding Architecture: Both incorporate shielded design with bezel EMI finger protection
- Temperature Rating: Both operate across -40°C ~ 85°C range
- Regulatory Compliance: Both are ROHS3 compliant with EAR99 ECCN classification
The primary difference is the Cat5 rating of the substitute versus Cat5e for the main part; however, Cat5 connectors are backward compatible with Cat5e applications. The substitute also offers Board Edge/Cutout mounting capability in addition to through-hole, providing design flexibility.

Engineering Selection Recommendations
The TE Connectivity 1116062-2 is the designated substitute for the obsolete Molex 0446611021. Selection is based on:
- Product Status Alignment: The substitute maintains active product status, ensuring long-term availability and manufacturing support
- Regulatory Compliance: Both parts meet ROHS3 requirements and carry identical ECCN/HTSUS classifications, eliminating compliance barriers
- Electrical and Mechanical Equivalence: Identical contact configuration, termination method, temperature rating, and shielding architecture ensure direct functional replacement
- Enhanced Mounting Flexibility: The substitute supports both through-hole and board edge/cutout mounting, providing design optimization opportunities without sacrificing compatibility
The Cat5 rating of the substitute is suitable for Cat5e applications, as Cat5 connectors maintain backward compatibility with higher category standards.
Frequently Asked Questions (FAQ)
Q: Can the TE Connectivity 1116062-2 directly replace the Molex 0446611021 in existing designs?
A: Yes. Both connectors share identical 8p8c jack configuration, 90° right-angle orientation, solder termination, phosphor bronze gold-plated contacts, and operating temperature range. PCB footprints and electrical performance are equivalent.
Q: What is the significance of the Cat5 versus Cat5e rating difference?
A: Cat5 connectors are fully compatible with Cat5e applications. The Cat5 rating of the substitute meets or exceeds the electrical performance requirements of Cat5e systems. No functional degradation occurs when substituting Cat5 for Cat5e in this connector class.
Q: Does the substitute's additional Board Edge/Cutout mounting capability affect compatibility?
A: No. The substitute retains through-hole mounting capability identical to the main part. The additional mounting options provide design flexibility without impacting existing through-hole implementations.
Q: Are there packaging differences between these parts?
A: The main part packaging is unspecified. The substitute is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.
Q: Do both parts meet the same regulatory and compliance standards?
A: Yes. Both parts are ROHS3 compliant with EAR99 ECCN classification and identical HTSUS codes. MSL ratings are equivalent at Level 1 (Unlimited).
