Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJ08D08 is determined by strict compatibility of the following core parameters:

• Connector Type: Jack (8p8c RJ45/Ethernet)
• Orientation: 90° right-angle positioning required
• Mounting Type: Through-hole solder termination
• Number of Positions/Ports: 8 pins, 8 contacts, 2-row configuration
• Tab Direction: Up and Down orientation
• Contact Material & Finish: Phosphor bronze with gold plating

The RJSAE538H08 functions as a direct mechanical and electrical substitute, maintaining all core connector specifications while offering improvements in electromagnetic shielding and environmental protection.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538H08 is the appropriate substitute for the obsolete RJSNEJ08D08. Both connectors maintain identical mechanical and electrical interface specifications, supporting 8p8c (RJ45/Ethernet) connectivity with through-hole solder termination and 90° right-angle mounting.

The RJSAE538H08 offers the following advantages:

• Active Product Status: The substitute is actively manufactured and supported, ensuring long-term availability and procurement continuity.
• Enhanced Shielding: Incorporates electromagnetic interference (EMI) finger shielding, providing improved signal integrity in environments with electromagnetic noise.
• Extended Temperature Range: Rated for -55°C to 85°C operation, extending the lower temperature limit by 15°C compared to the original part.
• Increased Gold Plating Thickness: 50.0µin (1.27µm) contact finish provides enhanced durability and corrosion resistance compared to 30.0µin (0.76µm).
• Regulatory Compliance: Both parts maintain RoHS compliance, EAR99 export classification, and MSL 1 handling requirements.

Frequently Asked Questions (FAQ)

Q: Can RJSAE538H08 directly replace RJSNEJ08D08 in existing PCB designs?

A: Yes. Both connectors share identical mechanical footprints, pin configurations (8p8c RJ45), through-hole mounting requirements, and solder termination specifications. No PCB redesign is required.

Q: What is the difference between shielded and unshielded configurations?

A: The original RJSNEJ08D08 is unshielded, offering minimal electromagnetic interference protection. The RJSAE538H08 includes EMI finger shielding, which reduces radiated emissions and improves immunity to external electromagnetic interference. Shielded variants are suitable for environments with higher noise requirements or stringent EMI compliance standards.

Q: Are the contact finishes compatible?

A: Yes. Both parts use phosphor bronze contacts with gold plating. The RJSAE538H08 features thicker gold plating (50.0µin vs. 30.0µin), which improves contact longevity and resistance to wear and oxidation.

Q: Does the extended operating temperature range of RJSAE538H08 affect compatibility?

A: No. The RJSAE538H08 supports -55°C to 85°C operation, which encompasses the original -40°C to 85°C range. Applications requiring the original temperature range remain fully compatible.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNEJ08D08 and RJSAE538H08 are RoHS compliant and maintain MSL 1 (unlimited) moisture sensitivity ratings.

Q: What does "Tab Direction: Up and Down" mean?

A: This indicates that the mechanical release tabs on the connector interface are oriented both upward and downward, providing secure mating and unmating forces consistent with standard RJ45 connector specifications.
