Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 555077-2 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Connector type (Jack), contact configuration (6p4c RJ11/RJ14), termination method (Solder), shielding classification (Unshielded), and performance rating (Cat3).

Mechanical Parameters: Mounting type (Surface Mount), orientation (90° Angle Right), housing material (Polyamide/Nylon), contact material (Phosphor Bronze), contact finish (Gold at 50.0µin thickness), and tab direction (Down).

Environmental Parameters: Operating temperature range (-40°C to +85°C) and moisture sensitivity level (MSL 1 - Unlimited).

The substitute part 5555077-2 satisfies all these criteria while offering the additional advantage of active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5555077-2 is the direct functional equivalent for the obsolete 555077-2 modular jack connector. Both components share identical electrical and mechanical specifications across all critical parameters, ensuring direct interchangeability in circuit design and PCB layout.

The 5555077-2 offers significant advantages for new designs and component replenishment:

Product Status: The substitute maintains active product status, ensuring long-term availability and supply chain continuity. The obsolete status of the original part creates sourcing risk for ongoing production requirements.

Regulatory Compliance: The 5555077-2 achieves RoHS3 compliance, whereas the original part is RoHS non-compliant. This compliance improvement aligns with current environmental regulations and customer requirements for restricted substance management.

Packaging: The substitute is supplied in Tray packaging, providing standardized handling and inventory management compared to the unspecified packaging of the original part.

All three components share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, maintaining consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 5555077-2 be used as a direct replacement for the 555077-2 in existing designs?

A: Yes. The 5555077-2 is electrically and mechanically identical to the 555077-2 across all specified parameters. No design modifications are required for substitution. Both components feature identical 6p4c contact configuration, 90-degree right-angle orientation, solder termination, and operating temperature range.

Q: What is the difference between the 555077-2 and 5555077-2 part numbers?

A: The primary differences are product status and regulatory compliance. The 555077-2 is obsolete and RoHS non-compliant, while the 5555077-2 is an active product with RoHS3 compliance. The base product number differs by one digit (555077 versus 5555077), but all functional specifications remain identical.

Q: Does packaging differ between these components?

A: Yes. The 5555077-2 is supplied in Tray packaging, while the original 555077-2 packaging is not specified. Tray packaging provides standardized handling for automated assembly processes and inventory management systems.

Q: Are there any electrical performance differences between these connectors?

A: No. Both components are rated for Category 3 performance and feature identical contact materials (Phosphor Bronze), contact finish (Gold at 50.0µin thickness), and unshielded construction. Electrical performance is equivalent.

Q: What is the operating temperature range for these connectors?

A: Both the 555077-2 and 5555077-2 operate across the temperature range of -40°C to +85°C. This specification is identical for both components.

Q: Are these connectors suitable for RJ11 and RJ14 applications?

A: Yes. Both connectors are specified for 6p4c (RJ11, RJ14) configurations. The 6-position 4-contact design accommodates standard RJ11 and RJ14 jack applications.

Q: What is the moisture sensitivity level for these components?

A: Both components carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage or handling.

Q: Is the 5555077-2 available in higher quantities than the 555077-2?

A: Current inventory data indicates 1292 pieces of the 5555077-2 are in stock compared to 896 pieces of the 555077-2. However, inventory levels are subject to change and should be verified at the time of procurement.
