Substitute Part Grouping Explanation

Substitution of the TE Connectivity 520258-2 is based on strict equivalence across all electrical and mechanical parameters. The substitute part 5520258-2 maintains identical specifications in the following critical areas:

Electrical Compatibility:

• Connector type, position count, and contact configuration (6p4c RJ11/RJ14)
• Contact material and finish specifications
• Category 3 ratings and unshielded construction
• Operating temperature range (-40°C ~ 85°C)

Mechanical Compatibility:

• Through-hole vertical mounting orientation
• Solder termination method
• Housing material composition
• Board lock and panel stop features
• User-selectable tab direction

Compliance Differentiation: The substitute part 5520258-2 differs from the main part in product status (active versus obsolete), RoHS compliance status, and REACH classification. These differences do not affect functional or mechanical interchangeability but provide improved regulatory standing for new applications.

Engineering Selection Recommendations

The TE Connectivity 5520258-2 is the direct functional equivalent for the obsolete 520258-2 modular connector. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part 520258-2 is classified as obsolete, limiting availability for new procurement. The substitute part 5520258-2 maintains active product status, ensuring continued supply chain access and manufacturer support.

Regulatory Compliance: The substitute part 5520258-2 achieves RoHS compliance, whereas the main part is non-compliant. For applications subject to RoHS directives or customer requirements, the substitute part satisfies regulatory obligations. Additionally, the substitute part is REACH unaffected, eliminating REACH-related compliance considerations present in the main part.

Electrical and Mechanical Equivalence: All functional parameters remain identical between the main and substitute parts. The 6p4c jack configuration, vertical through-hole mounting, solder termination, phosphor bronze contacts with gold finish, and Category 3 ratings are preserved. Operating temperature range, housing material, and mechanical features are unchanged.

Packaging Consideration: The substitute part is supplied in tray packaging, which may differ from the original packaging specification. Tray packaging is standard for active production components and does not affect functional performance or board-level integration.

For new designs and ongoing procurement, the TE Connectivity 5520258-2 is the appropriate selection. For legacy system repairs requiring exact original specifications, the main part 520258-2 remains functionally identical where availability permits.

Frequently Asked Questions (FAQ)

Q: Are the 520258-2 and 5520258-2 electrically interchangeable?

A: Yes. Both parts are jack modular connectors with identical 6p4c (RJ11/RJ14) contact configurations, phosphor bronze contacts with gold finish, and Category 3 ratings. Electrical performance and signal integrity are equivalent.

Q: Can the 5520258-2 be used as a direct replacement in existing designs using the 520258-2?

A: Yes. The substitute part maintains identical mechanical and electrical specifications, including through-hole vertical mounting, solder termination, board lock features, and operating temperature range (-40°C ~ 85°C). Direct substitution is supported at the board level.

Q: What is the significance of the RoHS compliance difference?

A: The main part 520258-2 is RoHS non-compliant, while the substitute 5520258-2 is RoHS compliant. For applications subject to RoHS directives (EU 2011/65/EU) or customer requirements mandating RoHS compliance, the substitute part is required. For legacy systems without RoHS requirements, both parts are functionally equivalent.

Q: Does the REACH status difference affect component selection?

A: The main part is REACH affected, indicating potential substances of concern under REACH regulations. The substitute part is REACH unaffected, eliminating regulatory documentation and compliance requirements. For applications in REACH-regulated markets or with REACH-compliant supply chain requirements, the substitute part is preferred.

Q: What is the packaging difference between these parts?

A: The main part 520258-2 packaging is not specified in available documentation. The substitute part 5520258-2 is supplied in tray packaging, which is standard for active production components. Tray packaging does not affect functional performance or board-level integration.

Q: Why is the main part 520258-2 classified as obsolete?

A: Obsolescence classification indicates the part is no longer in active production. The substitute part 5520258-2 is the active equivalent, ensuring continued availability and manufacturer support for new procurement and design implementations.

Q: Are there any performance differences between the two parts?

A: No. Both parts maintain identical electrical and mechanical performance specifications. Differences are limited to product status, regulatory compliance certifications, and packaging format.

Q: Can the 520258-2 be used in new designs?

A: While the 520258-2 is functionally equivalent, its obsolete status limits procurement viability for new designs. The TE Connectivity 5520258-2 is the recommended selection for new applications, providing active product status and improved regulatory compliance.
