TE Connectivity 555980-1 Modular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 555980-1 is a jack modular connector designed for 4p4c (RJ9, RJ10, RJ22) applications with 90° right-angle orientation and unshielded construction. This connector features through-hole solder termination, board lock functionality, and Cat3 rating for telecommunications and data applications.

The 555980-1 carries an obsolete product status, making identification of active equivalent parts essential for ongoing procurement and design continuity. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability in existing circuit designs and PCB layouts.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 555980-1 is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute part, TE Connectivity 5555980-1, maintains complete compatibility through identical specifications in the following critical areas:

Electrical Compatibility Parameters:

• Connector type (Jack)
• Contact configuration (4p4c RJ9/RJ10/RJ22)
• Contact material and finish (Phosphor Bronze with 50.0µin gold plating)
• Category rating (Cat3)
• Shielding configuration (Unshielded)

Mechanical Compatibility Parameters:

• Mounting type (Through Hole)
• Orientation (90° right angle)
• Termination method (Solder)
• Housing material (PBT/Polyester)
• Operating temperature range (-40°C to 85°C)
• Board lock feature (Present)
• Tab direction (Down)

The 5555980-1 substitute differs only in product status (Active versus Obsolete) and regulatory compliance status, with no functional or dimensional variations affecting circuit performance or PCB integration.

Parameter Comparison

Engineering Selection Recommendations

The 5555980-1 serves as the direct active equivalent to the obsolete 555980-1. Selection between these parts is determined by regulatory and procurement requirements rather than functional performance.

For applications requiring RoHS compliance: The 5555980-1 is the appropriate selection, as it carries RoHS Compliant certification. The 555980-1 is RoHS non-compliant and unsuitable for designs subject to RoHS regulations.

For applications with REACH compliance requirements: The 5555980-1 is REACH Unaffected, making it the preferred choice for supply chains requiring REACH compliance documentation. The 555980-1 carries REACH Affected status.

For legacy system maintenance and repair: Where original part specifications are mandated and regulatory compliance is not a constraint, the 555980-1 remains functionally equivalent. However, procurement availability is limited to existing inventory (851 pieces), whereas the 5555980-1 maintains active production status with higher inventory availability (2400 pieces).

Packaging consideration: The 5555980-1 is supplied in Tray packaging, whereas the 555980-1 packaging specification is not provided. Verify packaging requirements for automated assembly or bulk handling operations.

All electrical and mechanical parameters are identical between these parts, ensuring direct PCB-level interchangeability without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 5555980-1 be used as a direct replacement for the 555980-1 in existing designs?

A: Yes. The 5555980-1 is electrically and mechanically identical to the 555980-1 across all functional parameters including connector type, contact configuration, mounting orientation, termination method, and operating temperature range. No design modification is required for substitution.

Q: What is the primary reason for substituting the 555980-1?

A: The 555980-1 carries an obsolete product status, limiting long-term procurement availability. The 5555980-1 is an active product with established supply continuity, making it the recommended choice for new designs and ongoing production.

Q: Are there compliance differences between these parts?

A: Yes. The 5555980-1 is RoHS Compliant and REACH Unaffected, while the 555980-1 is RoHS non-compliant and REACH Affected. Applications subject to RoHS or REACH regulations must use the 5555980-1.

Q: Do these connectors have identical pinout and contact spacing?

A: Yes. Both parts feature 4p4c (RJ9, RJ10, RJ22) contact configuration with identical contact material (Phosphor Bronze), finish (Gold at 50.0µin thickness), and mechanical positioning. Pinout and contact spacing are identical.

Q: What is the difference in packaging between these parts?

A: The 5555980-1 is supplied in Tray packaging. The 555980-1 packaging specification is not documented. Confirm packaging requirements for your assembly process before procurement.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C, ensuring thermal performance equivalence in all specified environments.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. The 90° right-angle orientation, through-hole mounting type, solder termination, board lock feature, and tab direction (Down) are identical. Both parts mount identically to PCB layouts without modification.

Q: What is the contact finish specification for both parts?

A: Both parts feature gold-plated Phosphor Bronze contacts with a finish thickness of 50.0µin (1.27µm), ensuring identical electrical contact resistance and corrosion resistance characteristics.
