Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI-10022 is determined by strict alignment of the following critical parameters:

• Connector Type & Port Configuration: RJ45 connector with 4 ports in single-row arrangement
• Mounting & Orientation: Through-hole PCB mounting with 90° right-angle orientation
• Electrical Application: 10/100 Base-T or Base-TX networking standard with AutoMDIX support
• Termination Method: Solder-based connection to PCB
• Mechanical Compatibility: Height above board within acceptable tolerance range (13.61mm to 13.84mm)
• Shielding & EMI Protection: Shielded design with EMI finger and board guide features
• Contact & Finish Specifications: Gold-plated contacts for reliable signal transmission

The identified substitute part J8064E64NL from Pulse Electronics meets all critical substitution criteria while maintaining functional equivalence for 10/100 Base-T networking applications.

Engineering Selection Recommendations

SI-10022 (Stewart Connector): Select this part for applications requiring RoHS non-compliant component specifications. The connector is actively produced with established supply availability (1049 units in stock). Suitable for legacy systems or applications where RoHS compliance is not a regulatory requirement.

J8064E64NL (Pulse Electronics): This substitute part is recommended for new designs and applications requiring RoHS compliance. The connector demonstrates superior supply availability (326,747 units in stock) and is actively maintained in production. Operating temperature range is specified at 0°C to 70°C, providing defined thermal performance parameters. The substitute maintains electrical and mechanical equivalence while offering enhanced regulatory compliance status.

Both connectors are REACH unaffected and classified under ECCN EAR99, with identical HTSUS coding (8536.69.4040), confirming trade classification equivalence.

Frequently Asked Questions (FAQ)

Q: Can J8064E64NL directly replace SI-10022 in existing PCB designs?

A: Yes. Both connectors share identical RJ45 4-port configuration, through-hole mounting, 90° right-angle orientation, solder termination, and board guide features. Height above board measurements (13.84mm vs. 13.61mm) are within acceptable mechanical tolerance for standard PCB layouts. No circuit or layout modifications are required.

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

A: Both specifications support 10/100 Mbps Ethernet transmission with AutoMDIX capability. Base-TX is the standard twisted-pair implementation. The functional performance for networking applications is equivalent.

Q: Why does SI-10022 show RoHS non-compliant status while J8064E64NL is RoHS compliant?

A: RoHS compliance status reflects manufacturing process and material composition at the time of certification. J8064E64NL meets current RoHS directive requirements, making it suitable for applications subject to RoHS regulations. SI-10022 remains a valid substitute for applications without RoHS compliance mandates.

Q: Are there differences in contact finish thickness between these connectors?

A: SI-10022 specifies 50.0µin (1.27µm) gold contact finish thickness, while J8064E64NL specifies 30.0µin (0.76µm). Both thicknesses provide adequate gold plating for reliable electrical contact and corrosion resistance in 10/100 Base-T applications.

Q: What packaging format is available for J8064E64NL?

A: J8064E64NL is supplied in tray packaging, suitable for automated assembly processes and bulk component handling.

Q: Are both connectors suitable for the same operating temperature range?

A: J8064E64NL specifies an operating temperature range of 0°C to 70°C. SI-10022 does not provide an explicit operating temperature specification in the available data. For applications requiring defined thermal performance parameters, J8064E64NL provides documented temperature specifications.
