Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SI-60102-F are qualified based on the following critical parameters:

• Connector Type & Port Configuration: All substitutes must be RJ45 connectors with 4 ports in a single row
• Mounting & Orientation: Through-hole mounting with 90° right-angle orientation is mandatory
• Electrical Application: 10/100 Base-T or 10/100 Base-TX with AutoMDIX support
• Termination Method: Solder termination required
• Shielding & EMI Protection: Shielded design with EMI finger protection
• Environmental Compliance: RoHS compliance and MSL 1 rating required
• Physical Compatibility: Height above board within acceptable tolerance range (13.49mm to 13.84mm)

The two identified substitutes meet these core criteria while offering variations in contact material, contact finish thickness, operating temperature range, and packaging format.

Parameter Comparison

Engineering Selection Recommendations

7499031120A (Würth Elektronik WE-RJ45 LAN)

This substitute is suitable for applications requiring extended operating temperature range (-40°C to 85°C). The part maintains ROHS3 compliance and MSL 1 rating. The height above board (13.49mm) is within acceptable tolerance. Contact finish thickness is reduced to 30.0µin, which remains within industry standards for gold-plated connectors. Tin contact material provides reliable electrical performance in 10/100 Base-T applications. Tube packaging is appropriate for automated assembly processes.

J8064D648ANL (Pulse Electronics PULSEJACK™ J8)

This substitute is qualified for 10/100 Base-TX applications with AutoMDIX. Operating temperature range is 0°C to 70°C, suitable for standard commercial environments. RoHS compliance is confirmed. The height above board (13.61mm) is within acceptable tolerance. Phosphor bronze contact material with 30.0µin gold finish provides reliable performance. Tray packaging supports manual and semi-automated assembly. LED color sequence (Green-Yellow) differs from the primary part but maintains functional equivalence.

Both substitutes maintain core electrical and mechanical compatibility with the SI-60102-F. Selection should be based on specific application requirements including operating temperature, packaging format, and supply availability.

Frequently Asked Questions (FAQ)

Q: Can the 7499031120A be used in applications requiring -40°C operation?

A: Yes. The 7499031120A operates from -40°C to 85°C, making it suitable for extended temperature range applications where the SI-60102-F operating temperature is not specified.

Q: What is the difference between 10/100 Base-T and 10/100 Base-TX?

A: Both support 10/100 Mbps Ethernet with AutoMDIX capability. Base-TX is a specific implementation of Base-T. The J8064D648ANL is rated for Base-TX applications and is functionally equivalent for standard 10/100 networking.

Q: Does the reduced contact finish thickness (30.0µin vs 50.0µin) affect reliability?

A: No. Both 30.0µin and 50.0µin gold plating meet industry standards for RJ45 connectors. The 50.0µin thickness on the SI-60102-F provides additional margin; the 30.0µin on substitutes remains within acceptable specifications for 10/100 Base-T applications.

Q: Are the LED color differences (Yellow-Green vs Green-Yellow) functionally significant?

A: No. LED color sequence indicates link and activity status. Both sequences provide equivalent functional indication. Selection should be based on PCB design and visual preference.

Q: Which substitute is better for automated assembly?

A: The 7499031120A in tube packaging is optimized for automated pick-and-place assembly. The J8064D648ANL in tray packaging is suitable for manual and semi-automated processes.

Q: Can these substitutes be used interchangeably on the same PCB?

A: Yes, provided the PCB footprint accommodates the height variation (13.49mm to 13.84mm). All three connectors use identical through-hole solder termination and 90° right-angle orientation.

Q: What is the inventory status of substitute parts?

A: 7499031120A: 909 units in stock. J8064D648ANL: 905 units in stock. Both are actively produced and available for immediate procurement.
