Key Parameters

Substitute Part Grouping Explanation

Substitution of the SI-30005 is determined by strict alignment of the following critical parameters:

• Connector Type & Port Configuration: RJ45 jack with 8 ports in 2-row arrangement
• Mounting & Orientation: Through-hole mounting with 90° right-angle orientation
• Electrical Interface: Solder termination for PCB integration
• Shielding & EMI Protection: Shielded construction with EMI finger for electromagnetic interference mitigation
• Contact Properties: Gold finish at 50.0µin thickness for reliable signal transmission
• Environmental Compliance: ROHS3 compliance and REACH unaffected status required
• Moisture Sensitivity: MSL 1 rating for unlimited shelf life

The Molex 0445200001 meets all substitution criteria as a functionally equivalent 8-port RJ45 modular connector jack with identical mounting, orientation, shielding, and contact specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the SI-30005 and 0445200001 are active production components with identical compliance certifications. Selection between these parts should be based on:

• Supply Availability: SI-30005 has 933 units in stock; 0445200001 has 956 units in stock
• Regulatory Compliance: Both parts meet ROHS3 and REACH requirements
• Environmental Rating: Both parts carry MSL 1 classification, suitable for unlimited shelf-life storage
• Series Compatibility: SI-30005 belongs to the MagJack® ST SI-30000 series; 0445200001 belongs to the Molex 44520 series

No additional testing or verification is required when substituting between these parts, provided PCB layout accommodates the physical dimensions and mounting footprint.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0445200001 be used as a direct replacement for the SI-30005 in existing designs?

A: Yes. Both connectors share identical electrical specifications, mounting type, orientation, shielding configuration, and contact properties. PCB footprint compatibility must be verified during design review.

Q: What are the key differences between these two connectors?

A: The primary differences are manufacturer identity and series designation. The SI-30005 is part of Stewart Connector's MagJack® ST SI-30000 series, while the 0445200001 belongs to Molex's 44520 series. Functionally, they are equivalent for 10/100 Base-T Ethernet applications.

Q: Are there any compliance or environmental concerns when switching between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 moisture sensitivity ratings. They meet identical regulatory requirements.

Q: Does packaging format affect substitution?

A: The SI-30005 packaging is not specified in available data. The 0445200001 is supplied in tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What applications are these connectors suitable for?

A: Both connectors are rated for 10/100 Base-T Ethernet with AutoMDIX support (SI-30005) or Cat5 compliance (0445200001). They are suitable for network interface cards, switches, routers, and other Ethernet connectivity applications.

Q: Are LED indicators available on these connectors?

A: No. Both the SI-30005 and 0445200001 do not contain integrated LED indicators. LED functionality must be implemented separately on the host PCB if required.
