Substitute Part Grouping Explanation

Substitution between the TE Connectivity 558250-1 and 5558250-1 is based on electrical and mechanical parameter equivalence. Both connectors share identical specifications across all critical functional parameters:

Electrical Equivalence Parameters:

• 8p8c (RJ45, Ethernet) contact configuration
• Cat3 performance rating
• Phosphor bronze contacts with 50.0µin gold finish
• Shielded design

Mechanical Equivalence Parameters:

• 90° right-angle orientation
• Through-hole solder termination
• Board lock and panel stop features
• Tab direction (Down)
• Operating temperature range (-40°C ~ 85°C)
• Moisture sensitivity level 1

Packaging Difference: The primary distinction between these parts is packaging format: 558250-1 is supplied in standard packaging, while 5558250-1 is supplied in Tray packaging. This difference does not affect connector performance or compatibility.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement: The 5558250-1 is the recommended selection. This part maintains full electrical and mechanical equivalence to the 558250-1 while offering the following advantages:

• Active product status ensures long-term availability and supply chain stability
• ROHS3 compliance satisfies current regulatory requirements for electronic components
• REACH Unaffected status eliminates substance of concern restrictions
• Tray packaging provides standard handling and storage compatibility

For Legacy System Support: The 558250-1 remains functionally equivalent for applications where the connector is already integrated into existing designs. However, procurement of this obsolete part may face supply constraints.

Compliance Considerations: Organizations subject to RoHS3 or REACH regulations should transition to the 5558250-1 to maintain regulatory compliance. The electrical and mechanical performance of both connectors is identical, ensuring drop-in compatibility in existing circuit board designs.

Frequently Asked Questions (FAQ)

Q: Can the 5558250-1 directly replace the 558250-1 in existing designs?

A: Yes. The 5558250-1 provides complete electrical and mechanical equivalence. All contact configurations, termination methods, orientation, and performance ratings are identical. The connector will function identically in existing through-hole solder applications.

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

A: The primary differences are product status, regulatory compliance, and packaging format. The 558250-1 is obsolete and RoHS non-compliant, while the 5558250-1 is active and ROHS3 compliant. Electrically and mechanically, both connectors are equivalent.

Q: Does the tray packaging of the 5558250-1 affect connector performance?

A: No. Packaging format does not affect electrical or mechanical performance. Tray packaging is a standard handling and storage format that provides equivalent protection and organization compared to alternative packaging methods.

Q: Are there any circuit board layout modifications required when substituting the 5558250-1 for the 558250-1?

A: No. Both connectors share identical mounting specifications, including through-hole footprint, orientation, and mechanical features. No PCB redesign is necessary.

Q: What is the Cat3 rating, and does it apply to both connectors?

A: Cat3 (Category 3) is a telecommunications standard for twisted-pair cabling and connectors, supporting data transmission up to 10 Mbps. Both the 558250-1 and 5558250-1 are rated for Cat3 performance.

Q: Are these connectors suitable for outdoor or high-humidity applications?

A: Both connectors operate within the temperature range of -40°C to 85°C and carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. Shielded design provides protection against electromagnetic interference.

Q: What is the contact finish thickness, and why is it specified?

A: Both connectors feature 50.0µin (1.27µm) gold plating on phosphor bronze contacts. This thickness specification ensures consistent electrical conductivity, corrosion resistance, and contact reliability over the connector's operational life.
