SI-50211-F Equivalent & Substitute Parts

Part Overview

The SI-50211-F is a 1 Port RJ45 Through Hole modular connector manufactured by Stewart Connector, designed for 10/100 Base-T and AutoMDIX applications. This connector features a 90° right angle orientation with solder termination and is mounted through the PCB with a 0.550" height above board. The part is currently Active in product status and maintains full inventory availability. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility is required within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI-50211-F is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Height Above Board: 0.550" (13.97mm)
• Shielding: Shielded
• Number of Cores per Jack: 4
• Contact Finish: Gold

Application Compatibility:

• 10/100 Base-T or 10/100 Base-TX network applications
• AutoMDIX support

The substitute part J1012F01CNL from Pulse Electronics meets all mandatory matching parameters and maintains full electrical and mechanical compatibility within the specified application range.

Parameter Comparison

Engineering Selection Recommendations

Both the SI-50211-F and J1012F01CNL are Active products with full regulatory compliance. The SI-50211-F carries ROHS3 Compliant status, while the J1012F01CNL is RoHS Compliant. Both parts maintain REACH Unaffected status and carry the same ECCN and HTSUS classifications. Selection between these parts should be based on availability, packaging requirements (Tray for J1012F01CNL), and LED indicator color preference (Green-Green versus Yellow-Green). The electrical and mechanical compatibility is established through matching critical parameters including connector type, port configuration, mounting method, orientation, termination type, and board height.

Frequently Asked Questions (FAQ)

Q: Can J1012F01CNL be used as a direct replacement for SI-50211-F?

A: Yes. Both connectors share identical critical parameters including RJ45 type, 1 port configuration, through-hole mounting, 90° right angle orientation, solder termination, and 0.550" board height. Both support 10/100 network applications with AutoMDIX functionality.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer (Stewart Connector versus Pulse Electronics), LED indicator colors (Green-Green versus Yellow-Green), contact material composition (Copper Alloy versus Phosphor Bronze), contact finish thickness (50.0µin versus 15.0µin), and packaging format (standard versus Tray). Both maintain gold contact finish and shielded construction.

Q: Are there any compliance or regulatory differences?

A: Both parts are RoHS compliant and REACH unaffected. The SI-50211-F carries ROHS3 Compliant designation while the J1012F01CNL is RoHS Compliant. Both share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: Does the difference in contact finish thickness affect performance?

A: Contact finish thickness is provided as a specification parameter. Both parts maintain gold plating suitable for 10/100 Base-T and Base-TX applications. Selection should be based on design requirements and availability.

Q: What is the significance of the LED color difference?

A: LED color indicates link and activity status. The SI-50211-F uses Green-Green indicators while the J1012F01CNL uses Yellow-Green. Selection depends on PCB design requirements and visual indication preferences for network status monitoring.

Q: Are both parts suitable for production use?

A: Both parts are Active products with full inventory availability. The SI-50211-F has 702 pieces in stock while the J1012F01CNL has 1465 pieces available. Both are suitable for production applications.
