Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the TE Connectivity 555164-1 is based on the following critical parameters that must align for functional compatibility:

Direct Equivalency Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Orientation: 90° Angle (Right)
• Mounting Type: Through Hole
• Termination: Solder
• Tab Direction: Down
• Operating Temperature Range: -40°C ~ 85°C

Allowable Variation Parameters:

• Shielding: Unshielded designs are directly equivalent; shielded variants represent functional upgrades
• Ratings: Cat3 is the baseline; Cat5e and higher ratings are backward compatible
• Contact Finish Thickness: Variations in gold plating thickness do not affect functional compatibility
• Housing Material: Different polymer compositions (PBT, LCP) maintain mechanical and electrical performance
• Product Status: Active parts are preferred over obsolete parts for new procurement
• RoHS Compliance: Compliance status affects regulatory and supply chain considerations

Substitute parts are grouped into two categories: direct equivalents (matching all critical parameters) and compatible alternatives (matching critical parameters with allowable variations in shielding or ratings).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 5555164-1

The TE Connectivity 5555164-1 is the direct functional equivalent to the 555164-1. This part maintains identical electrical and mechanical specifications across all critical parameters: 8p8c jack configuration, 90° right-angle orientation, through-hole solder termination, unshielded design, and Cat3 rating. The primary advantage of 5555164-1 is its active product status and RoHS compliance, addressing the obsolescence of the original part. Packaging is supplied in tray format with significantly higher inventory availability (39,440 pieces in stock versus 1,129 pieces for the original part).

Secondary Substitute: Molex 0855045001

The Molex 0855045001 provides functional compatibility with the 555164-1 while introducing a shielded design and Cat5e rating upgrade. This part matches all critical parameters except shielding and rating category. The shielded construction and higher Cat5e rating represent performance enhancements suitable for applications requiring improved electromagnetic interference rejection or higher bandwidth capacity. The part is active and ROHS3 compliant. Selection of this part is appropriate when shielding benefits the application design.

Tertiary Substitute: Pulse Electronics E5388-000012-L

The Pulse Electronics E5388-000012-L maintains functional equivalency to the 555164-1 with identical unshielded design and Cat3 rating. This part matches all critical parameters and is RoHS compliant. However, the part is classified as obsolete, limiting its suitability for new procurement despite current inventory availability (4,221 pieces in stock). This part is suitable only for replacement or repair of existing assemblies where supply continuity is not a concern.

Compliance Considerations:

The original 555164-1 is RoHS non-compliant and REACH affected. The 5555164-1 direct equivalent is RoHS compliant with undefined REACH status. The Molex 0855045001 is ROHS3 compliant and REACH unaffected, providing the strongest regulatory position. Selection should account for end-product compliance requirements and supply chain restrictions.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5555164-1 be used as a direct replacement for the 555164-1?

A: Yes. The 5555164-1 is a direct functional equivalent with identical electrical and mechanical specifications. All critical parameters match: 8p8c jack 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 RoHS compliance (compliant versus non-compliant).

Q: What is the difference between the unshielded 555164-1 and the shielded Molex 0855045001?

A: The primary difference is electromagnetic shielding. The 555164-1 is unshielded and rated Cat3, while the 0855045001 is shielded and rated Cat5e. Shielding reduces electromagnetic interference susceptibility. The Cat5e rating of the 0855045001 supports higher bandwidth applications compared to the Cat3 rating of the 555164-1. Both parts share identical connector type, orientation, mounting, and termination specifications.

Q: Are there packaging differences between substitute parts?

A: Yes. The original 555164-1 is supplied without specified packaging. The 5555164-1 direct equivalent 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 format may affect handling, storage, and procurement processes but does not affect electrical or mechanical performance.

Q: Which substitute part should be selected for new product designs?

A: The TE Connectivity 5555164-1 is the recommended choice for new designs. This part is active, RoHS compliant, and functionally identical to the obsolete 555164-1. If the application requires shielding or higher bandwidth capacity, the Molex 0855045001 is suitable as an upgraded alternative. The Pulse Electronics E5388-000012-L should not be selected for new designs due to its obsolete status.

Q: Can these connectors be used interchangeably in existing assemblies?

A: The 5555164-1 and E5388-000012-L can be used interchangeably with the 555164-1 in existing assemblies due to identical critical parameters. The Molex 0855045001 can be used as a replacement if the application design accommodates shielded connectors and the higher Cat5e rating does not create compatibility issues with existing infrastructure.

Q: What is the significance of the contact finish thickness differences?

A: The 555164-1 and 5555164-1 specify 50.0µin (1.27µm) gold finish thickness. The Molex 0855045001 specifies flash gold finish. The Pulse Electronics E5388-000012-L specifies 6.00µin (0.152µm) gold finish thickness. These variations do not affect functional compatibility or electrical performance. Contact finish thickness influences durability and wear resistance in high-cycle mating applications but does not impact initial electrical characteristics.

Q: Are there temperature operating range differences between substitute parts?

A: No. All substitute parts share the identical operating temperature range of -40°C to 85°C. Temperature performance is equivalent across all options.

Q: What compliance certifications should be considered when selecting a substitute?

A: The original 555164-1 is RoHS non-compliant and REACH affected. The 5555164-1 is RoHS compliant with undefined REACH status. The Molex 0855045001 is ROHS3 compliant and REACH unaffected. The Pulse Electronics E5388-000012-L is RoHS compliant and REACH unaffected. Selection should align with end-product regulatory requirements and supply chain restrictions applicable to the target market.
