Substitute Part Grouping Explanation

The RJSNEJF8KA8 can be substituted by the RJSAE538EA8 based on equivalence in the following critical parameters that determine functional and mechanical interchangeability:

• Connector Type: Both are jack connectors
• Contact Configuration: Both feature 8p8c (RJ45/Ethernet) positioning
• Mounting Method: Both utilize through-hole solder termination
• Mechanical Orientation: Both provide 90° right-angle orientation
• Shielding: Both incorporate shielded designs
• Tab Direction: Both feature up and down tab orientation
• Housing Material: Both use thermoplastic construction
• Contact Material: Both utilize phosphor bronze contacts with gold plating
• Compliance: Both are RoHS compliant with MSL 1 rating
• Electrical Category: Both fall within the modular connector category for Ethernet/networking applications

The substitute part extends the operating temperature range and incorporates additional EMI shielding features while maintaining core electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538EA8 is the appropriate replacement for the obsolete RJSNEJF8KA8. Both components carry RoHS compliance certification and MSL 1 rating, ensuring conformance to contemporary regulatory and environmental standards. The substitute part maintains all core functional and mechanical characteristics required for seamless integration into existing PCB designs using through-hole solder termination.

The RJSAE538EA8 offers enhanced specifications including an extended operating temperature minimum of -55°C (compared to -40°C) and increased contact gold plating thickness (50.0µin versus 30.0µin), along with integrated EMI finger shielding. These enhancements provide superior electromagnetic interference rejection for noise-sensitive networking applications without degrading compatibility with the original design footprint and electrical interface.

Frequently Asked Questions (FAQ)

Q: Can RJSAE538EA8 be directly substituted for RJSNEJF8KA8 without PCB redesign? A: Yes. Both connectors share identical through-hole mounting configuration, 90° right-angle orientation, solder termination method, and 8p8c RJ45 contact positioning. Footprint and electrical interface compatibility is maintained.

Q: What are the differences in shielding between these two connectors? A: The RJSNEJF8KA8 provides standard shielding, while the RJSAE538EA8 incorporates additional EMI finger shielding. This enhancement improves electromagnetic interference attenuation without affecting mechanical or electrical compatibility.

Q: How do contact finish thicknesses differ, and does this impact selection? A: The RJSNEJF8KA8 features 30.0µin (0.76µm) gold plating, while RJSAE538EA8 provides 50.0µin (1.27µm). The thicker plating on the substitute part offers enhanced durability and wear resistance in high-insertion-cycle applications.

Q: What is the operating temperature advantage of RJSAE538EA8? A: The RJSAE538EA8 supports operation from -55°C to 85°C, expanding the lower temperature limit by 15°C compared to the RJSNEJF8KA8 (-40°C to 85°C). This is beneficial for applications in cold-ambient environments.

Q: Are both parts RoHS compliant? A: Yes. Both RJSNEJF8KA8 and RJSAE538EA8 carry RoHS compliance certification and MSL 1 moisture sensitivity rating, meeting modern supply chain and environmental requirements.

Q: Why is the RJSNEJF8KA8 listed as obsolete? A: Amphenol ICC has transitioned this part to end-of-life status. The RJSAE538EA8 from the RJSAE series represents the active production alternative with equivalent or superior specifications.
