Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete RJSNEJ38BA8 with the RJSAE538B08 is valid based on equivalence in the following critical parameters:

• Connector Type & Contact Configuration: Both are 8p8c (RJ45, Ethernet) jack connectors with identical pinout
• Mechanical Interface: Both feature 90° right-angle right orientation with through-hole mounting and solder termination
• Electrical & EMI Protection: Both provide shielded design with EMI finger protection and phosphor bronze contacts with gold finish
• Housing & Materials: Both use thermoplastic housing, maintaining identical form factor and thermal performance
• Regulatory Compliance: Both are RoHS compliant and carry identical ECCN and HTSUS classifications

The RJSAE538B08 represents an active-status alternative within the same product family, maintaining full electrical and mechanical compatibility while extending the operating temperature range and improving contact finish thickness specifications.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538B08 is the direct substitute for the obsolete RJSNEJ38BA8. Both components are manufactured by Amphenol ICC within the same connector family and meet identical RoHS compliance and international trade classification requirements. The RJSAE538B08 provides superior operational margins with an extended lower operating temperature specification (-55°C vs. -40°C) and increased contact finish thickness (50.0µin vs. 30.0µin), enhancing long-term reliability and durability in contact mating cycles. The active product status of RJSAE538B08 ensures continued availability and supply chain support for current procurement and future production runs.

Frequently Asked Questions (FAQ)

Q: Are RJSNEJ38BA8 and RJSAE538B08 electrically compatible? A: Yes. Both connectors provide 8p8c (RJ45, Ethernet) jack interfaces with identical pinout, contact materials, and shielding configurations. They are electrically equivalent for all standard Ethernet applications.

Q: Do these connectors have identical physical footprints? A: Yes. Both connectors use 90° right-angle through-hole mounting with identical housing geometry and termination pad layout, ensuring direct mechanical substitution on PCBs designed for either part.

Q: What is the significance of the contact finish thickness difference? A: The RJSAE538B08 features 50.0µin gold finish compared to 30.0µin on the RJSNEJ38BA8. This increased thickness provides extended wear resistance and improved contact durability over the connector's service life.

Q: Can the RJSAE538B08 operate in the same temperature range as the RJSNEJ38BA8? A: The RJSAE538B08 exceeds the temperature range of the original part, operating from -55°C to 85°C compared to -40°C to 85°C. Applications previously qualified to the RJSNEJ38BA8 remain fully compatible.

Q: What packaging format is available for the RJSAE538B08? A: The RJSAE538B08 is supplied in tray packaging, suitable for automated assembly processes and high-volume production environments.

Q: Are both parts RoHS compliant? A: Yes. Both RJSNEJ38BA8 and RJSAE538B08 are RoHS compliant and carry identical ECCN and HTSUS classifications, ensuring compliance with international trade and environmental regulations.
