Substitute Part Grouping Explanation
The RJSAE538H08 qualifies as a direct substitute for the RJSNEJF8H08 based on identical electrical and mechanical parameters. Both connectors match in the following critical specifications:
- Connector type and contact configuration (8p8c jack)
- Physical orientation (90° right-angle)
- Mounting methodology (through-hole, solder termination)
- Shielding configuration (shielded construction)
- Contact material composition (phosphor bronze with gold finish)
- Housing material (thermoplastic)
- Environmental compliance (RoHS compliant, MSL 1)
- Electrical contact rating specifications
The RJSAE538H08 includes an EMI finger in its shielding design and operates across a wider temperature range (-55°C ~ 85°C versus -40°C ~ 85°C), providing enhanced performance characteristics.

Engineering Selection Recommendations
The RJSAE538H08 is the appropriate selection for new designs and component reprocurement. As an active product from the same manufacturer, it ensures long-term availability and supply chain stability. Both parts maintain RoHS compliance and unlimited moisture sensitivity rating, satisfying environmental regulatory requirements.
The RJSAE538H08 offers enhanced performance through thicker gold plating (50.0µin versus 30.0µin) and extended lower temperature operating limit (-55°C versus -40°C), supporting broader application environments. The addition of EMI finger shielding in the substitute part provides improved electromagnetic interference rejection.
For existing designs utilizing the RJSNEJF8H08, direct substitution with the RJSAE538H08 is feasible without circuit redesign due to equivalent pin configurations, mounting footprints, and electrical characteristics. The upgrade path presents no compatibility concerns for PCB layouts designed for the original component.
Frequently Asked Questions (FAQ)
Q: Are the RJSNEJF8H08 and RJSAE538H08 pin-compatible?
A: Yes. Both connectors feature identical 8p8c (RJ45/Ethernet) contact configurations with matching pin assignments and solder pad layouts for through-hole mounting.
Q: What is the difference between the EMI finger in the RJSAE538H08 and standard shielding?
A: The EMI finger is an integral component of the shield that enhances electromagnetic interference suppression. Both parts provide shielded construction; the RJSAE538H08 incorporates an additional EMI mitigation feature.
Q: Can I use the RJSNEJF8H08 in new designs?
A: No. The RJSNEJF8H08 is classified as obsolete and subject to discontinuation. New designs must utilize the RJSAE538H08 to ensure component availability and manufacturing support.
Q: What is the impact of the thicker gold plating on the RJSAE538H08?
A: The increased contact finish thickness (50.0µin versus 30.0µin) enhances contact durability and corrosion resistance, extending component lifespan under repeated mating cycles.
Q: Are there environmental or regulatory differences between these parts?
A: Both parts are RoHS compliant with MSL 1 rating. The RJSAE538H08 supports a lower operating temperature limit (-55°C), expanding the qualified temperature range for cold environment applications.
Q: Can existing PCBs designed for RJSNEJF8H08 accommodate the RJSAE538H08?
A: Yes. The mechanical footprint and electrical interface are equivalent, enabling direct mounting without PCB modification.
