Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ385A8 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Shielding: Shielded, EMI Finger
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• Tab Direction: Up and Down
• Board Lock Feature: Present

Allowable Variation Parameters:

• Contact Finish Thickness: Variation permitted within industry tolerance
• Operating Temperature Range: Substitute must support minimum -40°C and maximum 85°C
• Product Status: Active status preferred for ongoing availability

The RJSAE-5385-08 meets all mandatory matching parameters and is therefore classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE-5385-08 is the direct substitute for the obsolete RJSNEJ385A8. Both parts are manufactured by Amphenol ICC (Commercial Products) and share identical functional and mechanical specifications for 8p8c (RJ45, Ethernet) jack connectors with 90° right-angle orientation and solder termination.

Compliance and Certification: Both parts maintain RoHS compliance and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, ensuring regulatory equivalence for procurement and export purposes.

Operational Compatibility: The RJSAE-5385-08 operates across an extended temperature range (-55°C ~ 85°C) compared to the RJSNEJ385A8 (-40°C ~ 85°C), providing enhanced thermal performance for demanding applications. The contact finish thickness of the RJSAE-5385-08 (50.0µin / 1.27µm) exceeds that of the RJSNEJ385A8 (30.0µin / 0.76µm), offering improved contact durability and wear resistance.

Supply Chain Status: The RJSAE-5385-08 maintains active product status with 771 units in stock, ensuring reliable availability for new designs and replacement requirements. The RJSNEJ385A8, classified as obsolete, is no longer recommended for new designs.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE-5385-08 directly replace the RJSNEJ385A8 in existing designs?

A: Yes. Both connectors are functionally and mechanically equivalent for 8p8c (RJ45, Ethernet) applications. They share identical connector type, pin configuration, mounting method, orientation, termination type, shielding, and board lock features. No design modifications are required.

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

A: The RJSAE-5385-08 features a thicker gold contact finish (50.0µin versus 30.0µin). This provides extended contact life and improved resistance to wear and corrosion, particularly in high-cycle mating applications.

Q: Does the extended operating temperature range of the RJSAE-5385-08 affect compatibility?

A: No. The RJSAE-5385-08 supports the full operating range of the RJSNEJ385A8 (-40°C ~ 85°C) and extends capability to -55°C. This represents an enhancement with no compatibility concerns.

Q: Are there packaging differences between these parts?

A: The RJSNEJ385A8 packaging is not specified in available data. The RJSAE-5385-08 is supplied in Tray packaging. Confirm packaging requirements with your procurement specification.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are RoHS compliant, carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, and maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Why is the RJSNEJ385A8 classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Amphenol ICC. The RJSAE-5385-08 represents the current active equivalent for this connector type.
