Substitute Part Grouping Explanation

Direct substitution of the RJSNE508408 is based on strict alignment of the following critical parameters:

• Connector Type: Jack (8p8c/RJ45 Ethernet)
• Orientation: 90° angle right configuration
• Mounting Type: Through hole solder termination
• Shielding: Unshielded design
• Contact Configuration: Phosphor bronze with 50.0µin gold plating
• Operating Temperature: Minimum -40°C compatibility
• Regulatory Compliance: RoHS compliant

The RJSAE508408 satisfies all substitution criteria while offering the additional advantage of active product status and board lock feature, making it the qualified equivalent for new designs and obsolescence replacement applications.

Engineering Selection Recommendations

The RJSAE508408 is the qualified direct substitute for RJSNE508408 applications. Selection is supported by:

• Product Status Transition: The RJSAE508408 maintains active manufacturing status, ensuring long-term supply continuity compared to the obsolete RJSNE508408.
• Compliance Equivalence: Both parts maintain identical RoHS compliance and EAR99 export classifications, with matching HTSUS codes (8536.69.4040).
• Thermal Capability: The RJSAE508408 extends the lower operating temperature limit to -55°C, providing enhanced performance margin for cold environment applications while maintaining the identical upper limit of 85°C.
• Mechanical Compatibility: Identical connector type, orientation, mounting configuration, and termination method ensure drop-in replacement capability in through-hole PCB designs.
• Additional Value: The integrated board lock feature in RJSAE508408 provides mechanical retention enhancement without altering electrical or physical interface compatibility.

Frequently Asked Questions (FAQ)

Q: Can RJSAE508408 replace RJSNE508408 in existing designs without PCB modification? A: Yes. Both connectors share identical through-hole mounting footprints, electrical contact configurations, and mechanical interfaces. No PCB layout changes are required.

Q: What is the difference between the two connector series? A: The RJSNE and RJSAE series differ in product lifecycle status and features. RJSAE508408 is the active equivalent with board lock functionality, while RJSNE508408 is obsolete. Both maintain equivalent electrical performance and mechanical compatibility.

Q: Does the extended operating temperature range of RJSAE508408 affect compatibility? A: No. The extended lower temperature limit (-55°C versus -40°C) represents a capability enhancement with no negative impact on compatibility. Designs originally specified for -40°C operation are fully supported.

Q: Are the packaging formats interchangeable? A: Packaging format (tray versus alternative methods) affects supply chain logistics and storage but does not alter electrical or mechanical properties. Component selection criteria remain unchanged.

Q: Does the board lock feature add any electrical characteristics? A: The board lock is a mechanical retention feature providing additional physical stability. It does not modify electrical performance, contact resistance, or signal transmission characteristics.

Q: What are the key parameters that must match for reliable substitution? A: Critical substitution parameters include connector type (jack 8p8c/RJ45), orientation (90° right angle), mounting method (through hole solder), shielding configuration (unshielded), contact materials and finish specifications, and operating temperature compatibility. All parameters listed in the Key Parameters section must align for electrical and mechanical equivalence.
