Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 555165-2 is determined by strict electrical and mechanical parameter matching. The following criteria establish functional equivalence:

Critical Matching Parameters:

• Connector type (Jack)
• Contact configuration (6p4c / RJ11, RJ14 compatibility)
• Mounting method (Through Hole)
• Orientation (90° Angle Right)
• Termination method (Solder)
• Shielding classification (Unshielded)
• Performance rating (Cat3)
• Contact material and finish specifications
• Housing material composition
• Operating temperature range (-40°C ~ 85°C)
• Tab direction (Down)
• Board lock feature presence

The substitute part 5555165-2 meets all electrical and mechanical parameters required for direct substitution. The primary distinction between the main part and its substitute is product status (obsolete versus active) and packaging configuration (unspecified versus tray), with improved RoHS compliance status in the substitute variant.

Engineering Selection Recommendations

The TE Connectivity 5555165-2 is the direct functional equivalent for the obsolete 555165-2 modular connector. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The main part 555165-2 is classified as obsolete, while the substitute 5555165-2 maintains active product status. This distinction ensures continued availability, manufacturer support, and supply chain reliability for both new designs and field service applications.

Compliance Status: The substitute part 5555165-2 achieves RoHS compliance, whereas the main part is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS-compliant components, the substitute part satisfies these regulatory requirements without functional compromise.

Electrical and Mechanical Equivalence: All critical parameters determining connector functionality are identical between the main part and substitute. The 6p4c configuration, 90° right-angle orientation, solder termination, unshielded design, Cat3 performance rating, phosphor bronze contacts with gold finish, and operating temperature range are fully matched.

Packaging Configuration: The substitute part is supplied in tray packaging, which is standard for production environments and provides improved handling and inventory management compared to unspecified packaging.

Frequently Asked Questions (FAQ)

Q: Can the 5555165-2 be used as a direct replacement for the 555165-2 in existing designs?

A: Yes. The 5555165-2 is electrically and mechanically equivalent to the 555165-2. All connector parameters including pin configuration, orientation, termination method, and performance ratings are identical. The substitute part can be used in new production and field replacements without design modification.

Q: What is the significance of the product status difference between these parts?

A: The 555165-2 is classified as obsolete, indicating that TE Connectivity no longer manufactures or supports this part number. The 5555165-2 maintains active status, ensuring continued availability, technical support, and supply chain reliability. For new designs and ongoing production, the active substitute part is the appropriate selection.

Q: Does the RoHS compliance difference affect compatibility?

A: The RoHS compliance difference does not affect electrical or mechanical compatibility. However, if your application or customer requirements mandate RoHS-compliant components, the 5555165-2 satisfies these regulatory requirements. The 555165-2, being RoHS non-compliant, may not be acceptable for such applications.

Q: Are the contact specifications identical between these parts?

A: Yes. Both parts feature phosphor bronze contacts with gold finish at 50.0µin (1.27µm) thickness. Contact material, finish type, and thickness specifications are fully matched, ensuring equivalent electrical performance and reliability.

Q: What is the difference in packaging between these parts?

A: The 555165-2 has unspecified packaging, while the 5555165-2 is supplied in tray packaging. Tray packaging is standard for production environments and provides improved component protection and inventory management. This difference does not affect the connector's functional performance.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 555165-2 and 5555165-2 operate across the identical temperature range of -40°C to 85°C. There are no thermal performance differences between these parts.

Q: Can these connectors be used in shielded applications?

A: No. Both parts are unshielded connectors. If electromagnetic shielding is required for your application, a different connector design must be selected.

Q: What is the Cat3 performance rating?

A: Cat3 (Category 3) is a telecommunications performance standard applicable to these modular connectors. This rating indicates the connector's performance characteristics for voice and data transmission applications. Both parts meet this standard identically.
