Parameter Comparison

Engineering Selection Recommendations

The RJSAE508608 is the qualified substitute for the obsolete RJSNEJ083A8 based on the following engineering criteria:

Functional Equivalence: Both connectors share identical core specifications for jack modular connector applications: 8p8c (RJ45, Ethernet) configuration, 90° right-angle orientation, through-hole solder termination, and unshielded design. Electrical and mechanical interface compatibility is confirmed.

Compliance Status: The RJSAE508608 maintains RoHS compliance and MSL 1 rating, matching the original part's regulatory requirements. Both parts are manufactured by Amphenol ICC (Commercial Products), ensuring consistent quality standards and manufacturing processes.

Enhanced Specifications: The substitute part offers improved performance characteristics: extended operating temperature range (-55°C to 85°C versus -40°C to 85°C) and increased contact finish thickness (50.0µin versus 30.0µin), providing enhanced durability and reliability. The addition of board lock feature provides mechanical stability without compromising electrical performance.

Active Product Status: The RJSAE508608 is classified as active, ensuring long-term availability and supply chain stability for production and design requirements.

Frequently Asked Questions (FAQ)

Q: Can RJSAE508608 be used as a direct replacement for RJSNEJ083A8 in existing designs?

A: Yes. The RJSAE508608 meets all core electrical and mechanical specifications required for direct substitution. Both connectors feature identical 8p8c (RJ45, Ethernet) jack configuration, 90° right-angle orientation, through-hole solder termination, and unshielded design. PCB footprint and mounting hole patterns are compatible.

Q: What is the difference in contact finish thickness between these parts?

A: The RJSNEJ083A8 has 30.0µin (0.76µm) gold contact finish, while the RJSAE508608 has 50.0µin (1.27µm). The increased thickness in the substitute part enhances contact durability and wear resistance without affecting electrical performance or compatibility.

Q: Does the board lock feature on RJSAE508608 affect compatibility?

A: No. The board lock feature is a mechanical enhancement that improves connector retention on the PCB. It does not alter electrical characteristics, contact configuration, or mounting interface. The feature is fully compatible with designs originally specified for the RJSNEJ083A8.

Q: Are there packaging differences between these parts?

A: The RJSNEJ083A8 packaging format is not specified in the available data. The RJSAE508608 is supplied in tray packaging. Packaging format does not affect electrical or mechanical compatibility; it only impacts logistics and handling procedures.

Q: What is the temperature operating range difference?

A: The RJSNEJ083A8 operates from -40°C to 85°C, while the RJSAE508608 operates from -55°C to 85°C. The extended lower temperature limit of the substitute part provides additional operational margin and is fully backward compatible with the original specification range.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNEJ083A8 and RJSAE508608 are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting identical regulatory and environmental requirements.

Q: Why is RJSNEJ083A8 classified as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The RJSAE508608 represents the active equivalent in Amphenol ICC's current product portfolio, offering equivalent functionality with enhanced specifications and assured long-term availability.
