Key Parameters

Substitute Part Grouping Explanation

Substitution of the U77-C1114-1011 is determined by strict equivalence across the following critical parameters:

• Connector Type and Style: SFP cage configuration
• Mounting Architecture: Through-hole, right-angle orientation
• Termination Technology: Press-fit connection method
• Functional Features: EMI shielding and light pipe integration
• Series Designation: U77 family membership
• Compliance Standards: RoHS compliance and MSL rating

The substitute part U77-C1114-3011 maintains identical specifications across all these parameters while transitioning from obsolete to active product status. The primary distinction is the contact finish designation (NI suffix indicating nickel plating) and updated regulatory classification (EAR99 and HTSUS coding).

Parameter Comparison

Engineering Selection Recommendations

The U77-C1114-3011 is the direct functional equivalent for the obsolete U77-C1114-1011. Both components share identical electrical and mechanical specifications within the U77 series SFP cage connector family. The substitute part maintains full compliance with RoHS requirements and carries an MSL rating of 1, indicating no moisture sensitivity constraints during storage or handling.

Selection of the U77-C1114-3011 is appropriate for new designs, production restarts, and field replacements where the U77-C1114-1011 is no longer available. The active product status of the substitute ensures ongoing supply chain support and manufacturing continuity.

Frequently Asked Questions (FAQ)

Q: Are the U77-C1114-1011 and U77-C1114-3011 mechanically interchangeable?

A: Yes. Both connectors feature identical through-hole, right-angle mounting configurations and press-fit termination methods. PCB footprints and mounting hole patterns are equivalent.

Q: What is the functional difference between these two parts?

A: There is no functional difference. Both parts are SFP cage connectors with EMI shielding and light pipe features. The primary distinction is product status: the -1011 is obsolete while the -3011 is active.

Q: Does the contact finish designation affect electrical performance?

A: The contact finish (NI designation on the -3011) does not alter the electrical characteristics of the connector. Both parts maintain equivalent signal integrity and impedance properties.

Q: Are both parts RoHS compliant?

A: Yes. Both the U77-C1114-1011 and U77-C1114-3011 are RoHS compliant and carry an MSL rating of 1 (unlimited moisture sensitivity level).

Q: Can I use the U77-C1114-3011 as a direct replacement in existing assemblies?

A: Yes. The U77-C1114-3011 is a direct substitute for the U77-C1114-1011 in all applications where the original part was specified. No design modifications are required.

Q: What is the inventory status of these parts?

A: The U77-C1114-1011 has 1027 pieces in stock as new original inventory. The U77-C1114-3011 has 722 pieces in stock as new original inventory.
