TE Connectivity 558070-1 Modular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 558070-1 is a Jack Modular Connector with 10 positions and 10 contacts (RJ50) configured for 90° right-angle mounting with shielding and EMI finger protection. This connector is rated for Category 3 applications and features through-hole solder termination with a board guide.

The 558070-1 carries an obsolete product status, making identification of active equivalent parts necessary for ongoing procurement and design continuity. The substitute part 5558070-1 provides functional equivalence while maintaining active product availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution between the 558070-1 and 5558070-1 is valid based on electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical functional parameters:

Matching Parameters:

• Connector type (Jack)
• Contact configuration (10p10c RJ50)
• Mounting method (Through Hole)
• Orientation (90° right angle)
• Termination type (Solder)
• Shielding design (Shielded with EMI finger)
• Contact material and finish (Phosphor Bronze, Gold 50.0µin)
• Operating temperature range (-40°C ~ 85°C)
• Category rating (Cat3)
• Board guide feature

The primary distinction between these parts is product status and packaging format. The 558070-1 is obsolete, while the 5558070-1 maintains active status with tray packaging, enabling continued supply chain access.

Parameter Comparison

Engineering Selection Recommendations

The 5558070-1 is the direct active equivalent for the obsolete 558070-1. Selection between these parts should be based on the following criteria:

For New Designs and Procurement: Use the 5558070-1. This part maintains active product status, ensuring long-term supply chain availability and support. The 5558070-1 carries RoHS compliance certification, meeting current regulatory requirements for electronic components in most jurisdictions.

For Legacy System Maintenance: The 558070-1 remains available in inventory (1079 units) for applications requiring the original part number or non-compliant specifications. However, the 5558070-1 provides identical electrical and mechanical function and should be evaluated as a replacement option.

Compliance Consideration: The 5558070-1 is RoHS compliant, while the 558070-1 is non-compliant. Applications subject to RoHS regulations must use the 5558070-1. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Frequently Asked Questions (FAQ)

Q: Are the 558070-1 and 5558070-1 electrically interchangeable?

A: Yes. Both parts are Jack Modular Connectors with identical electrical specifications: 10p10c (RJ50) configuration, Category 3 rating, phosphor bronze contacts with gold finish (50.0µin), and operating temperature range of -40°C to 85°C.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance. The 558070-1 is obsolete and RoHS non-compliant. The 5558070-1 is active, RoHS compliant, and supplied in tray packaging. All functional and mechanical parameters are identical.

Q: Can I use the 5558070-1 as a direct replacement for the 558070-1 in existing designs?

A: Yes. The 5558070-1 provides direct functional replacement. Both parts feature identical through-hole solder termination, 90° right-angle orientation, shielding with EMI finger, and board guide features. No design modifications are required.

Q: Why does the 558070-1 show as obsolete?

A: The 558070-1 has been superseded by the 5558070-1 in the TE Connectivity product line. The newer part number maintains all functional specifications while providing active product status and RoHS compliance.

Q: What is the significance of the packaging difference?

A: The 558070-1 packaging is not specified, while the 5558070-1 is supplied in tray packaging. Tray packaging is standard for active production parts and facilitates automated assembly processes. This does not affect the connector's electrical or mechanical performance.

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

A: Both parts operate across the identical temperature range of -40°C to 85°C. Both feature shielding with EMI finger protection and are rated for Category 3 applications. No environmental limitations differ between the two parts.

Q: Which part should I specify for new procurement?

A: Specify the 5558070-1 for all new procurement. This part is active, RoHS compliant, and maintains higher inventory availability (10267 units versus 1079 units for the obsolete part).
