Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 555167-1 are classified based on alignment with the following critical parameters: connector type (Jack), contact configuration (8p8c RJ45), orientation (90° right-angle), mounting method (through-hole solder), and operating temperature range (-40°C to 85°C).

Direct Equivalent Classification: Parts maintaining identical electrical and mechanical specifications, including shielding type (unshielded) and performance rating (Cat3), are classified as direct equivalents.

Functional Substitute Classification: Parts that maintain core connector functionality but differ in secondary parameters such as shielding type, performance rating, or housing material are classified as functional substitutes. These parts accommodate design flexibility when the original specification can be upgraded or when alternative materials meet application requirements.

The substitution logic prioritizes:

1. Connector type and contact configuration match
2. Orientation and mounting method compatibility
3. Operating temperature range coverage
4. Termination method consistency
5. Regulatory compliance and product status considerations

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5555167-1 (Direct Equivalent): This part is the primary recommended substitute for the obsolete TE Connectivity 555167-1. It maintains identical electrical and mechanical specifications, including unshielded design, Cat3 rating, and all physical parameters. The 5555167-1 is classified as active product status with RoHS compliance and REACH unaffected status, providing regulatory advantages over the original part. Inventory availability is significantly higher (7308 units versus 847 units), supporting long-term procurement stability. This part is suitable for direct replacement in all applications where the original 555167-1 was specified.

Molex 0855045001 (Functional Substitute): This part provides functional substitution with key differences in shielding and performance rating. The 0855045001 features shielded design and Cat5e rating, representing an upgrade from the unshielded Cat3 specification of the original part. This connector is appropriate for applications where enhanced electromagnetic interference protection and higher performance capability are beneficial or required. The part maintains identical orientation, mounting method, and termination characteristics. RoHS3 compliance and REACH unaffected status provide regulatory advantages. Selection of this part requires confirmation that the shielded design and Cat5e rating are compatible with the application circuit design.

Pulse Electronics E5388-000012-L (Functional Equivalent): This part maintains electrical and mechanical compatibility with the original 555167-1, including unshielded design and Cat3 rating. However, the E5388-000012-L is classified as obsolete product status, limiting its suitability for new procurement activities. RoHS compliance and REACH unaffected status provide regulatory advantages over the original part. This connector is suitable only for replacement applications where existing inventory must be maintained or where the original part cannot be sourced through the TE Connectivity 5555167-1 alternative.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5555167-1 be used as a direct replacement for the 555167-1?

A: Yes. The 5555167-1 maintains identical electrical and mechanical specifications across all critical parameters: 8p8c RJ45 configuration, 90° right-angle orientation, through-hole solder termination, unshielded design, Cat3 rating, and operating temperature range. The primary differences are product status (active versus obsolete) and regulatory compliance (RoHS compliant and REACH unaffected versus non-compliant and affected). Direct substitution is appropriate for all applications.

Q: What are the implications of selecting the Molex 0855045001 shielded connector instead of the unshielded original part?

A: The Molex 0855045001 introduces shielding and upgrades the performance rating from Cat3 to Cat5e. Shielding provides enhanced electromagnetic interference rejection, which may be beneficial in electrically noisy environments. The Cat5e rating supports higher bandwidth applications. However, the shielded design may require different PCB layout considerations, including ground plane connections for the shield. The connector maintains identical orientation, mounting method, and termination approach. Selection requires confirmation that the application circuit design accommodates the shielded connector configuration.

Q: Are there packaging differences between the substitute parts?

A: Yes. The original TE Connectivity 555167-1 is supplied in unspecified packaging. The TE Connectivity 5555167-1 is supplied in tray packaging. The Molex 0855045001 is supplied in tray packaging. The Pulse Electronics E5388-000012-L is supplied in bulk packaging. Packaging differences may affect handling, storage, and assembly processes. Confirm packaging compatibility with receiving and assembly procedures before procurement.

Q: What is the significance of RoHS and REACH compliance differences?

A: RoHS compliance indicates restriction of hazardous substances in electrical and electronic equipment, with RoHS3 representing the most current standard. REACH compliance indicates registration, evaluation, authorization, and restriction of chemicals. The original 555167-1 is RoHS non-compliant and REACH affected, which may restrict use in certain regulated markets or applications. The substitute parts (5555167-1, 0855045001, and E5388-000012-L) are RoHS compliant and REACH unaffected, providing regulatory advantages for new designs and applications subject to environmental compliance requirements.

Q: Can the Pulse Electronics E5388-000012-L be used for new designs?

A: The E5388-000012-L maintains electrical and mechanical compatibility with the original 555167-1 and provides RoHS compliance and REACH unaffected status. However, the part is classified as obsolete product status. For new designs, the TE Connectivity 5555167-1 is the recommended selection due to active product status, higher inventory availability, and equivalent specifications. The E5388-000012-L is suitable only for replacement or maintenance applications where existing inventory must be sustained.

Q: What are the contact finish thickness differences, and do they affect connector performance?

A: The original TE Connectivity 555167-1 specifies 50.0µin (1.27µm) gold contact finish thickness. The Molex 0855045001 specifies flash gold finish thickness (not quantified). The Pulse Electronics E5388-000012-L specifies 6.00µin (0.152µm) gold contact finish thickness. Contact finish thickness affects durability and wear resistance during mating cycles. The 50.0µin specification on the original part and TE Connectivity 5555167-1 provides enhanced durability compared to the thinner finishes on alternative parts. For applications requiring extended mating cycle life, the TE Connectivity 5555167-1 is preferred.

Q: Are there housing material differences between the substitute parts?

A: Yes. The original TE Connectivity 555167-1 uses Polybutylene Terephthalate (PBT) with polyester composition. The TE Connectivity 5555167-1 uses identical PBT with polyester composition. The Molex 0855045001 uses Liquid Crystal Polymer (LCP) with glass filling, which provides enhanced mechanical and thermal properties. The Pulse Electronics E5388-000012-L uses PBT with glass filling. Housing material differences may affect mechanical strength, thermal stability, and dimensional tolerance. For applications with demanding mechanical or thermal requirements, the Molex 0855045001 LCP housing provides enhanced performance.
