SI-60073-F Equivalent & Substitute Parts

Part Overview

The SI-60073-F is a 1 Port RJ45 Through Hole 10/100 Base-T modular connector manufactured by Stewart Connector. This MagJack® ST SI-60000 series connector is designed for Ethernet applications requiring 10/100 Base-T connectivity with a 90° right-angle orientation and solder termination on printed circuit boards. The part is currently Active in product status with 1096 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to component availability, supply chain considerations, or design flexibility within the same application category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SI-60073-F is determined by strict equivalence across the following critical parameters:

• Connector Type & Port Configuration: RJ45 jack with single port, single row configuration
• Application Compatibility: 10/100 Base-T Ethernet connectivity
• Mechanical Interface: Through hole mounting with 90° right-angle orientation and solder termination
• Electrical Protection: Shielded design with EMI finger for electromagnetic interference mitigation
• Contact Specifications: Gold-plated finish at 50.0µin (1.27µm) thickness on copper alloy base material
• Regulatory Compliance: ROHS3 compliant, REACH unaffected, MSL 1 rating

The substitute part 1-5406299-1 (TE Connectivity AMP Connectors) meets all critical substitution criteria within the modular connector category for 10/100 Base-T applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SI-60073-F and 1-5406299-1 are Active product status components meeting ROHS3 compliance and REACH unaffected regulatory requirements. Selection between these parts should be based on:

• Availability: SI-60073-F has 1096 units in stock; 1-5406299-1 has 5539 units in stock
• Packaging: SI-60073-F packaging not specified; 1-5406299-1 supplied in Tray packaging
• Manufacturer Preference: Stewart Connector (original) versus TE Connectivity AMP Connectors (substitute)
• Operating Temperature: 1-5406299-1 specifies -40°C ~ 85°C operating range; SI-60073-F operating temperature not provided
• Housing Material Variant: SI-60073-F uses Thermoplastic; 1-5406299-1 uses Polyamide (PA), Nylon—both suitable for modular connector applications

Both parts satisfy 10/100 Base-T Ethernet connectivity requirements with equivalent electrical and mechanical interfaces.

Frequently Asked Questions (FAQ)

Q: Can 1-5406299-1 directly replace SI-60073-F in existing designs?

A: Yes. Both connectors share identical critical parameters: RJ45 jack configuration, single port, through hole mounting, 90° right-angle orientation, solder termination, shielded design with EMI finger, gold-plated contacts at 50.0µin thickness, and ROHS3/REACH compliance. The substitute meets all electrical and mechanical requirements for 10/100 Base-T applications.

Q: What is the difference in contact material between these parts?

A: SI-60073-F uses Copper Alloy contacts; 1-5406299-1 uses Phosphor Bronze contacts. Both materials are suitable for modular connector applications and provide equivalent electrical performance with gold plating.

Q: Does packaging affect substitution compatibility?

A: Packaging format (Tray for 1-5406299-1 versus unspecified for SI-60073-F) does not affect electrical or mechanical compatibility. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Are there differences in housing material?

A: SI-60073-F housing is Thermoplastic; 1-5406299-1 housing is Polyamide (PA), Nylon. Both materials are thermoplastic polymers suitable for modular connector housings and provide equivalent mechanical performance in 10/100 Base-T applications.

Q: What is the significance of MSL 1 rating for both parts?

A: MSL 1 (Unlimited) indicates these components have unlimited shelf life and do not require special moisture control during storage or handling, simplifying inventory and supply chain management.

Q: Why is operating temperature specified for 1-5406299-1 but not for SI-60073-F?

A: Operating temperature specification availability varies by manufacturer documentation. The -40°C ~ 85°C range provided for 1-5406299-1 represents the tested operating envelope for that component. Absence of specification for SI-60073-F does not indicate incompatibility; consult manufacturer datasheets for complete thermal performance data.
