Substitute Part Grouping Explanation

Substitution of the RJSNEJ082A8 is based on electrical and mechanical parameter equivalence within the modular connector category. The primary substitute, RJSAE508208, maintains functional compatibility through identical specifications in the following critical parameters:

• Connector type (Jack)
• Contact configuration (8p8c RJ45, Ethernet)
• Port and row count (8 ports, 2 rows)
• Mounting method (Through Hole)
• Orientation (90° right-angle)
• Termination method (Solder)
• Shielding classification (Unshielded)
• Contact material (Phosphor Bronze)
• Contact finish (Gold)
• Housing material (Thermoplastic)
• Environmental compliance (RoHS Compliant, MSL 1)

The RJSAE508208 represents an active product status alternative, ensuring continued availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE508208 is the direct substitute for the obsolete RJSNEJ082A8. Both components are manufactured by Amphenol ICC (Commercial Products) and maintain identical electrical and mechanical specifications for 8p8c modular jack connector applications.

Key differentiators between the two parts are:

1. Product Status: RJSNEJ082A8 is obsolete, while RJSAE508208 is active. The active status of RJSAE508208 ensures ongoing availability and supply chain support.

2. Contact Finish Thickness: RJSAE508208 provides increased gold plating thickness (50.0µin versus 30.0µin), offering enhanced durability and contact reliability.

3. Operating Temperature Range: RJSAE508208 extends the lower operating temperature limit to -55°C, compared to -40°C for the main part, providing broader environmental compatibility.

4. Additional Features: RJSAE508208 includes board lock functionality, enhancing mechanical retention during assembly and field deployment.

5. Compliance: Both parts maintain RoHS compliance and MSL 1 rating, ensuring regulatory and environmental standards adherence.

For new designs and production applications, RJSAE508208 is the recommended selection. For legacy system maintenance where RJSNEJ082A8 inventory exists, RJSAE508208 provides direct functional replacement with enhanced performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can RJSAE508208 directly replace RJSNEJ082A8 in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications for 8p8c modular jack applications, including connector type, contact configuration, mounting method, orientation, termination, and shielding. The RJSAE508208 is functionally equivalent and compatible with existing PCB layouts and assembly processes.

Q: What is the significance of the contact finish thickness difference?

A: The RJSAE508208 features 50.0µin (1.27µm) gold plating compared to 30.0µin (0.76µm) on the RJSNEJ082A8. Increased plating thickness provides extended contact life, improved corrosion resistance, and enhanced reliability in repeated mating cycles.

Q: Does the extended operating temperature range of RJSAE508208 affect compatibility?

A: No. The RJSAE508208 operating range of -55°C to 85°C encompasses the RJSNEJ082A8 range of -40°C to 85°C. The extended lower temperature capability of RJSAE508208 provides additional environmental flexibility without compromising compatibility in applications within the original temperature specification.

Q: What is the board lock feature on RJSAE508208?

A: Board lock is a mechanical retention feature that secures the connector to the PCB during assembly and field service. This feature enhances mechanical stability and reduces the risk of connector displacement due to vibration or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both RJSNEJ082A8 and RJSAE508208 are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting regulatory requirements for environmental and hazardous substance restrictions.

Q: What packaging differences exist between these parts?

A: RJSNEJ082A8 packaging information is not specified in the provided data. RJSAE508208 is supplied in tray packaging. Confirm packaging requirements with your procurement specifications.

Q: Why is RJSNEJ082A8 classified as obsolete?

A: Obsolescence classification indicates the part is no longer in active production. RJSAE508208, as an active product, ensures continued supply chain availability and manufacturer support for new and ongoing applications.
