Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJ384A8 is based on electrical and mechanical parameter equivalence within the modular connector category. The substitute part RJSAE538408 maintains functional compatibility through identical specifications in the following critical parameters:

• Connector type (Jack)
• Contact configuration (8p8c RJ45, Ethernet)
• Physical orientation (90° right-angle)
• Mounting methodology (through-hole solder termination)
• Shielding architecture (shielded with EMI finger)
• Contact material and finish (phosphor bronze with gold plating)
• Housing material (thermoplastic)
• Functional features (board lock, LED indicators)
• Tab direction (up and down)
• Regulatory compliance (RoHS compliant, MSL 1)

The substitute part differs in product status (active versus obsolete) and contact finish thickness, representing a direct functional equivalent suitable for design replacement.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538408 serves as the direct functional equivalent for the obsolete RJSNEJ384A8. Both parts are manufactured by Amphenol ICC (Commercial Products) and maintain identical electrical and mechanical specifications across all critical parameters required for 8p8c modular jack connector applications.

Selection of RJSAE538408 is supported by the following factors:

• Active product status ensures ongoing availability and manufacturing support
• Full RoHS compliance certification matches the original part
• Moisture sensitivity level (MSL 1) provides unlimited shelf life
• Operating temperature range of -55°C to 85°C exceeds the original specification of -40°C to 85°C, providing extended environmental capability
• Contact finish thickness of 50.0µin (1.27µm) provides enhanced durability compared to the original 30.0µin (0.76µm) specification
• Identical connector architecture, shielding, and termination methodology ensure direct mechanical and electrical compatibility

Frequently Asked Questions (FAQ)

Q: Can RJSAE538408 be used as a direct replacement for RJSNEJ384A8 in existing designs?

A: Yes. Both parts share identical specifications for connector type, contact configuration, orientation, mounting methodology, shielding, and termination. The substitute part maintains full functional compatibility for 8p8c RJ45 Ethernet applications.

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

A: The RJSNEJ384A8 features 30.0µin (0.76µm) gold plating, while the RJSAE538408 provides 50.0µin (1.27µm) gold plating. The increased thickness in the substitute part enhances contact durability and wear resistance.

Q: Does the operating temperature range difference affect compatibility?

A: The RJSAE538408 operates across -55°C to 85°C, compared to -40°C to 85°C for the RJSNEJ384A8. This extended lower temperature capability of the substitute part provides additional environmental margin and does not restrict compatibility in applications within the original temperature range.

Q: Are both parts RoHS compliant?

A: Yes. Both RJSNEJ384A8 and RJSAE538408 are RoHS compliant with MSL 1 (unlimited moisture sensitivity level), meeting current regulatory requirements for electronic component manufacturing and assembly.

Q: What packaging differences exist between these parts?

A: The RJSNEJ384A8 packaging specification is not provided in the available data. The RJSAE538408 is supplied in tray packaging. Verify packaging requirements for your specific procurement and assembly processes.

Q: Why is the RJSNEJ384A8 classified as obsolete?

A: Product obsolescence is determined by the manufacturer. The RJSAE538408, as an active product from the same manufacturer with equivalent specifications, provides continuity for ongoing production and field replacement requirements.
