TE Connectivity AMP Connectors 5555141-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 5555141-3 is a modular jack connector with 8 positions and 8 contacts (8p8c/RJ45 Ethernet configuration). This shielded connector features a 90° right-angle orientation, through-hole solder termination, and EMI finger shielding rated for Cat3 applications. The connector is actively manufactured and maintains full ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical specifications are required for design flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5555141-3 are identified based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack Modular Connector
• Positions/Contacts: 8p8c (RJ45, Ethernet)
• Orientation: 90° Angle (Right)
• Mounting Type: Through Hole
• Termination Method: Solder
• Shielding: Shielded with EMI Finger
• Contact Material: Phosphor Bronze
• Contact Finish: Gold (50.0µin / 1.27µm)
• Operating Temperature Range: -40°C to 85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Housing Material composition (Polyamide with or without glass fill)
• Category Rating (Cat3 or Cat4)
• Feature set (Board Lock presence/absence, Panel Stops)

The substitute parts Molex 0432028927 and Molex 0432028924 meet all mandatory matching criteria and are therefore electrically and mechanically interchangeable with the primary part number 5555141-3.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5555141-3 (Primary Part)

Select this part when the original design specification calls for Cat3 rating and the specific feature set including Panel Stops is required. This part maintains active production status with 1133 pieces in current inventory.

Molex 0432028927 (Direct Substitute)

This part provides direct substitution for the 5555141-3 with identical Cat3 rating and equivalent electrical performance. The housing material includes glass-filled polyamide, which provides enhanced mechanical stability. This part is actively manufactured with 1943 pieces in inventory. REACH status is confirmed as REACH Unaffected.

Molex 0432028924 (Upgraded Substitute)

This part provides substitution with enhanced Cat4 rating, suitable for applications requiring higher bandwidth capability than Cat3. The housing material includes glass-filled polyamide. This part is actively manufactured with 4086 pieces in inventory. REACH status is confirmed as REACH Unaffected. Selection of this part is appropriate when Cat4 performance is acceptable or required by system specifications.

All three parts maintain ROHS3 compliance, identical operating temperature ranges, and equivalent contact specifications. Selection between these parts depends on category rating requirements and feature set needs.

Frequently Asked Questions (FAQ)

Q: Can Molex 0432028927 be used as a direct replacement for TE Connectivity 5555141-3?

A: Yes. Both parts share identical specifications for connector type, contact configuration (8p8c RJ45), orientation (90° right angle), mounting method (through hole solder), shielding (EMI finger), contact materials and finish, operating temperature range, and compliance certifications. The Molex part includes glass-filled polyamide housing, which is a compatible material variation.

Q: What is the difference between the Molex 0432028927 and Molex 0432028924?

A: The primary difference is the category rating. The 0432028927 is rated Cat3, matching the original TE Connectivity part. The 0432028924 is rated Cat4, providing higher bandwidth capability. All other electrical and mechanical specifications are identical between these two Molex parts.

Q: Can I use the Molex 0432028924 (Cat4) in place of the TE Connectivity 5555141-3 (Cat3)?

A: Yes. The Cat4-rated Molex 0432028924 is electrically and mechanically compatible with the Cat3-rated TE Connectivity part. Cat4 rating represents enhanced performance and is backward compatible with Cat3 applications. All other specifications including contact materials, finish thickness, operating temperature, and compliance certifications are identical.

Q: Are there any differences in the housing material between these parts?

A: The TE Connectivity 5555141-3 uses polyamide (PA) nylon housing. Both Molex substitute parts use polyamide (PA) nylon with glass fill. Glass-filled polyamide provides improved mechanical strength and thermal stability while maintaining electrical equivalence.

Q: Do all three parts have the same solder termination compatibility?

A: Yes. All three parts use identical solder termination methods and are compatible with standard PCB assembly processes. Contact finish specifications (gold, 50.0µin / 1.27µm) are identical across all parts.

Q: What is the inventory status for these parts?

A: TE Connectivity 5555141-3 has 1133 pieces in stock. Molex 0432028927 has 1943 pieces in stock. Molex 0432028924 has 4086 pieces in stock. All parts are actively manufactured.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both Molex parts have confirmed REACH Unaffected status.
