Key Parameters

Substitute Part Grouping Explanation

The RJSNEJ08CA8 can be substituted with the RJSAE508708 based on the following critical compatibility parameters:

• Connector Type: Both are Jack connectors
• Positions/Contacts: Both feature 8p8c (RJ45/Ethernet) configuration
• Ports and Rows: Both have 8 ports and 2 rows
• Mounting Type: Both use through-hole solder termination
• Orientation: Both provide 90° right-angle mounting
• Shielding: Both are unshielded
• Tab Direction: Both feature up and down tab direction
• Contact Material: Both use Phosphor Bronze with gold finish
• Housing Material: Both use thermoplastic construction
• Compliance: Both are RoHS Compliant with MSL 1 rating

The substitution is valid where these core electrical and mechanical parameters are required for PCB assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE508708 is the direct substitute for the obsolete RJSNEJ08CA8. Both components maintain identical core electrical and mechanical specifications required for RJ45/Ethernet modular connector applications. The RJSAE508708 holds active product status, ensuring continued availability and manufacturing support.

Key differences between the two parts are:

• Operating Temperature Range: The RJSAE508708 extends the minimum operating temperature to -55°C, providing greater low-temperature capability compared to the RJSNEJ08CA8 at -40°C.
• Contact Finish Thickness: The RJSAE508708 provides enhanced contact durability with 50.0µin (1.27µm) gold plating versus 30.0µin (0.76µm) on the RJSNEJ08CA8.
• Board Lock Feature: The RJSAE508708 includes board lock functionality, absent in the RJSNEJ08CA8.
• Compliance and Certifications: Both components are RoHS Compliant with MSL 1 rating, ensuring regulatory compatibility across environmental and moisture sensitivity requirements.

Selection of RJSAE508708 eliminates obsolescence risk while maintaining full compatibility with existing PCB designs and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE508708 directly replace the RJSNEJ08CA8 in existing designs? A: Yes. Both connectors share identical core specifications for connector type, position count, mounting style, orientation, and solder termination. PCB footprint and electrical function are compatible.

Q: What is the significance of the Board Lock feature in RJSAE508708? A: The board lock provides mechanical retention between the connector and PCB during assembly and handling. This feature is absent in the RJSNEJ08CA8 but does not affect electrical compatibility or PCB footprint.

Q: How do the contact finish thicknesses differ, and does this impact selection? A: The RJSAE508708 provides 50.0µin (1.27µm) of gold plating compared to 30.0µin (0.76µm) on the RJSNEJ08CA8. The increased thickness on RJSAE508708 provides enhanced contact durability and corrosion resistance over extended product life cycles.

Q: What is the packaging difference between these parts? A: The RJSNEJ08CA8 packaging is unspecified, while RJSAE508708 is supplied in Tray packaging. Confirm packaging requirements with procurement specifications before ordering.

Q: Are both parts RoHS Compliant? A: Yes. Both RJSNEJ08CA8 and RJSAE508708 are RoHS Compliant with MSL 1 (Unlimited) rating, meeting environmental and moisture sensitivity requirements.

Q: Does the extended operating temperature range of RJSAE508708 affect my application? A: The RJSAE508708 operates from -55°C to 85°C versus -40°C to 85°C for RJSNEJ08CA8. If your application requires operation below -40°C, the RJSAE508708 provides additional margin. For standard commercial applications, both are functionally equivalent.

Q: Where can I source the RJSAE508708? A: Current inventory indicates 730 pieces of RJSAE508708 in stock as new original components. Confirm availability with authorized distributors.
