Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 557484-1 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitute relationships:

Critical Substitution Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Number of Ports: 1
• Number of Rows: 1
• Mounting Type: Through Hole
• Orientation: Vertical
• Termination: Solder
• Shielding: Shielded, EMI Finger
• Ratings: Cat3
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Contact Finish Thickness: 50.0µin (1.27µm)
• Housing Material: Polyester
• Operating Temperature Range: -40°C ~ 85°C
• Features: Board Lock, Panel Stops
• LED Color: Does Not Contain LED
• Tab Direction: User Selectable

Substitute parts must maintain identical electrical performance, mechanical fit, and environmental specifications. Variations in product status, packaging format, or compliance certifications do not affect functional substitutability when all electrical and mechanical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

The 5557484-1 is a direct functional equivalent to the 557484-1 across all electrical and mechanical specifications. Both connectors share identical pin configurations, contact materials, shielding characteristics, and operating parameters.

Product Status Consideration: The 557484-1 is classified as obsolete, while the 5557484-1 maintains active product status. Active status indicates ongoing manufacturer support, availability, and continued compliance maintenance.

Compliance Consideration: The 5557484-1 is RoHS Compliant, whereas the 557484-1 is RoHS non-compliant. For applications subject to RoHS regulations or requiring compliance with environmental directives, the 5557484-1 is the appropriate selection.

Packaging Consideration: The 5557484-1 is supplied in Tray packaging, which may differ from the original packaging format of the 557484-1. Packaging format does not affect electrical or mechanical performance and is determined by procurement and inventory management requirements.

Both parts are manufactured by TE Connectivity AMP Connectors and maintain identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Frequently Asked Questions (FAQ)

Q: Can the 5557484-1 be used as a direct replacement for the 557484-1?

A: Yes. The 5557484-1 is electrically and mechanically equivalent to the 557484-1. All contact configurations, pin assignments, shielding characteristics, and operating parameters are identical. The connectors are interchangeable in applications where the original 557484-1 was specified.

Q: What is the difference between the 557484-1 and 5557484-1?

A: The primary differences are product status, RoHS compliance, and packaging format. The 557484-1 is obsolete and RoHS non-compliant, while the 5557484-1 is an active product with RoHS Compliance. Both connectors have identical electrical and mechanical specifications. The 5557484-1 is supplied in Tray packaging.

Q: Does the RoHS compliance difference affect connector performance?

A: RoHS compliance status reflects manufacturing process and material sourcing standards, not connector performance.
