Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ38T08 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
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The RJSAE538B08 qualifies as a direct substitute because it maintains all mandatory electrical and mechanical parameters. Both connectors are manufactured by Amphenol ICC (Commercial Products) within the modular connector category and support identical functional requirements for 8p8c Ethernet jack applications with right-angle through-hole solder termination and shielded construction.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538B08 is the qualified substitute for the obsolete RJSNEJ38T08. Selection is based on the following engineering criteria:

Product Status: The RJSNEJ38T08 is obsolete, while the RJSAE538B08 maintains active product status with current manufacturing support and availability (863 Pcs in stock versus 820 Pcs for the obsolete part).

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

Functional Equivalence: All critical electrical and mechanical parameters align, including connector type, contact configuration, mounting method, orientation, termination style, shielding architecture, and contact materials. Both parts support identical 8p8c Ethernet jack applications with right-angle through-hole solder termination.

Enhanced Specifications: The RJSAE538B08 provides an 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), offering improved durability and thermal performance in demanding environments.

Packaging Consideration: The RJSAE538B08 is supplied in tray packaging, which may differ from the original part's packaging specification. Verify packaging compatibility with existing assembly and logistics processes.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538B08 directly replace the RJSNEJ38T08 in existing designs?

A: Yes. The RJSAE538B08 maintains all mandatory electrical and mechanical parameters required for direct substitution in 8p8c Ethernet jack applications. Both connectors feature identical connector type, contact configuration, mounting method, orientation, termination style, and shielding architecture. The substitute part is manufactured by the same supplier (Amphenol ICC) and carries active product status.

Q: What are the differences between these two parts?

A: The primary differences are product status (obsolete versus active), contact finish thickness (30.0µin versus 50.0µin), operating temperature range (-40°C to 85°C versus -55°C to 85°C), LED color options (red only versus red and green), and packaging format (unspecified versus tray). All functional parameters for connector operation remain identical.

Q: Does the increased contact finish thickness affect compatibility?

A: No. The increased contact finish thickness (50.0µin on the RJSAE538B08 versus 30.0µin on the RJSNEJ38T08) represents an enhancement that improves durability and wear resistance without affecting electrical or mechanical compatibility. This thicker gold plating provides superior performance in high-cycle mating applications.

Q: Are there any temperature-related limitations when substituting?

A: The RJSAE538B08 supports an extended lower temperature limit (-55°C versus -40°C), making it suitable for a broader range of operating environments. If the original design operates within the -40°C to 85°C range, the substitute part fully supports these conditions with additional margin at lower temperatures.

Q: What is the significance of the tray packaging for the substitute part?

A: The RJSAE538B08 is supplied in tray packaging, which may differ from the original part's packaging specification. Verify that tray packaging is compatible with your assembly equipment, handling procedures, and logistics infrastructure before finalizing procurement.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNEJ38T08 and RJSAE538B08 are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, ensuring regulatory equivalence for procurement and export purposes.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors can be stored and handled without special humidity control measures or time-limited shelf life constraints.
