TE Connectivity 558066-1 Modular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 558066-1 is a jack modular connector with 10 positions and 10 contacts (RJ50) configured for 90° right-angle mounting. This unshielded connector is designed for through-hole solder termination and operates within the Cat3 rating category. The 558066-1 is classified as obsolete, necessitating identification of active equivalent parts to ensure continued design support and procurement availability. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 558066-1 is based on 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 count (10p10c/RJ50), contact material (Phosphor Bronze), contact finish (Gold at 50.0µin thickness), and Cat3 rating.

Mechanical Parameters: 90° right-angle orientation, through-hole mounting, solder termination, unshielded configuration, polyamide housing, board guide and keyed features, and downward tab direction.

Environmental Parameters: Operating temperature range of -40°C to 85°C and Moisture Sensitivity Level 1 (Unlimited).

Parts meeting these criteria are classified as direct functional equivalents and may be substituted without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5558066-1 is the direct active equivalent for the obsolete 558066-1 modular connector. All electrical and mechanical parameters are identical, ensuring pin-for-pin and footprint-compatible substitution.

Primary Recommendation: Transition to part number 5558066-1 for new designs and production restocking. This part maintains full functional equivalence while offering improved product status (Active vs. Obsolete) and enhanced regulatory compliance (RoHS Compliant vs. RoHS non-compliant).

Compliance Advantage: The 5558066-1 achieves RoHS compliance, eliminating lead and other restricted substances while maintaining identical performance characteristics. This upgrade path supports long-term supply chain stability and regulatory alignment.

Packaging Consideration: The 5558066-1 is supplied in Tray packaging, whereas the 558066-1 packaging specification was not provided. Verify packaging requirements for your procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 5558066-1 be used as a direct replacement for the 558066-1 in existing designs?

A: Yes. The 5558066-1 is electrically and mechanically identical to the 558066-1 across all specified parameters, including connector type, contact configuration (10p10c/RJ50), orientation (90° right-angle), mounting method (through-hole solder), and operating temperature range (-40°C to 85°C). No circuit redesign or PCB layout modification is required.

Q: What is the primary difference between these two parts?

A: The 558066-1 is classified as obsolete with RoHS non-compliant status, while the 5558066-1 is an active product with RoHS compliance. The 5558066-1 also offers higher inventory availability (1457 pcs vs. 860 pcs) and is supplied in Tray packaging.

Q: Are there any electrical performance differences between the 558066-1 and 5558066-1?

A: No. Both parts share identical electrical specifications: Cat3 rating, phosphor bronze contacts with 50.0µin gold finish, unshielded configuration, and -40°C to 85°C operating temperature range.

Q: Does the packaging difference affect compatibility?

A: Packaging format (Tray vs. unspecified for 558066-1) does not affect electrical or mechanical compatibility. Packaging selection should be based on your assembly process requirements and handling procedures.

Q: Why should I transition from the 558066-1 to the 5558066-1?

A: The 5558066-1 provides supply chain continuity (active product status), regulatory compliance (RoHS), and improved inventory availability. The obsolete status of the 558066-1 creates long-term procurement risk.

Q: Are there any thermal or environmental limitations I should consider?

A: Both parts operate identically across the -40°C to 85°C temperature range with Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.
