Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJF8M08 is based on strict equivalence of the following critical parameters:

• Connector Type & Contact Configuration: Both main and substitute parts are 8p8c (RJ45, Ethernet) jack connectors with identical pin count and arrangement
• Mechanical Orientation: Both maintain 90° right-angle mounting orientation
• Termination Method: Both utilize solder termination for PCB integration
• Shielding Requirement: Both provide electromagnetic shielding
• Contact Material & Finish: Both employ phosphor bronze contacts with gold plating
• Housing Material: Both use thermoplastic housing
• Compliance Standards: Both are RoHS compliant with MSL 1 rating
• Mounting Interface: Both are through-hole mounted components

The RJSAE538708 qualifies as a direct substitute based on these aligned parameters, with the distinction that it represents an active product status and includes enhanced EMI finger shielding.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538708 is the qualified substitute for the obsolete RJSNEJF8M08 based on the following engineering criteria:

Electrical & Mechanical Equivalence: The RJSAE538708 maintains identical contact configuration, termination method, and mechanical orientation. Both connectors support 8p8c (RJ45, Ethernet) applications with through-hole solder termination and board lock functionality.

Enhanced Shielding: The RJSAE538708 incorporates EMI finger shielding in addition to standard shielding, providing improved electromagnetic interference rejection without compromising mechanical compatibility.

Extended Operating Temperature: The RJSAE538708 operates across -55°C to 85°C, extending the lower temperature limit by 15°C compared to the RJSNEJF8M08 (-40°C to 85°C). This expanded range accommodates broader environmental deployment scenarios.

Compliance & Certification: Both parts maintain RoHS compliance and MSL 1 rating, ensuring regulatory alignment and moisture handling equivalence.

Product Status: The RJSAE538708 holds active product status, ensuring long-term availability and supply chain continuity compared to the obsolete RJSNEJF8M08.

Contact Finish Thickness: The RJSAE538708 features 50.0µin (1.27µm) gold plating compared to 30.0µin (0.76µm) on the RJSNEJF8M08, providing enhanced contact durability and wear resistance.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538708 be used as a direct replacement for the RJSNEJF8M08 on existing PCB designs?

A: Yes. Both connectors share identical mechanical footprints, mounting hole patterns, and solder pad configurations. The through-hole mounting interface, 90° right-angle orientation, and board lock mechanism are functionally equivalent. No PCB redesign is required.

Q: What is the significance of the EMI finger feature on the RJSAE538708?

A: The EMI finger provides additional electromagnetic shielding through direct contact with the PCB ground plane. This enhancement reduces radiated emissions and improves noise immunity in high-speed Ethernet applications. The feature is backward compatible and does not affect mechanical or electrical substitution.

Q: Are there differences in contact reliability between these two connectors?

A: The RJSAE538708 features thicker gold plating (50.0µin versus 30.0µin), which extends contact life and improves resistance to corrosion and wear. Both connectors use identical phosphor bronze base material and maintain equivalent electrical performance.

Q: Does the extended operating temperature range of the RJSAE538708 affect compatibility?

A: No. The RJSAE538708 operates across -55°C to 85°C, which encompasses the RJSNEJF8M08 range of -40°C to 85°C. The extended lower temperature capability provides additional environmental flexibility without introducing incompatibility.

Q: What packaging differences exist between these parts?

A: The RJSNEJF8M08 packaging specification is not provided in the available data. The RJSAE538708 is supplied in tray packaging. Confirm packaging requirements with your procurement specification before ordering.

Q: Are both connectors suitable for Ethernet (RJ45) applications?

A: Yes. Both connectors are specified as 8p8c (RJ45, Ethernet) jack connectors and support standard Ethernet pinout configurations. The shielded design accommodates both Cat5e and Cat6 cabling standards.

Q: What is the inventory status for these parts?

A: The RJSNEJF8M08 (obsolete) has 1041 pieces in stock. The RJSAE538708 (active) has 1084 pieces in stock. For long-term production planning, the active status of RJSAE538708 ensures continued availability.
