Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJF84A8 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Contact Configuration: 8p8c (RJ45, Ethernet)
• Number of Ports: 8
• Number of Rows: 2
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination Method: Solder
• Shielding: Shielded
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• RoHS Compliance: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The RJSAE538408 satisfies all mandatory matching parameters and qualifies as a direct substitute. Both connectors maintain identical mechanical and electrical interface specifications, enabling direct replacement in through-hole PCB applications requiring 8p8c modular jack connectivity with right-angle orientation and shielding.

Engineering Selection Recommendations

The RJSAE538408 is the qualified substitute for the obsolete RJSNEJF84A8. Selection rationale is based on the following engineering criteria:

Product Status: The RJSNEJF84A8 is classified as obsolete, while the RJSAE538408 maintains active product status. Active status ensures ongoing availability, manufacturing support, and compliance with current regulatory requirements.

Regulatory Compliance: Both parts maintain RoHS Compliant certification and identical Moisture Sensitivity Level (MSL 1, Unlimited), confirming equivalence in environmental and regulatory standing.

Electrical and Mechanical Compatibility: The RJSAE538408 matches all critical interface parameters of the RJSNEJF84A8, including connector type, contact configuration, mounting method, orientation, and termination approach. Direct PCB footprint compatibility is maintained.

Enhanced Specifications: The RJSAE538408 provides improved contact finish thickness (50.0µin versus 30.0µin) and extended operating temperature range (-55°C to 85°C versus -40°C to 85°C), offering superior performance margins without compromising compatibility.

EMI Enhancement: The RJSAE538408 incorporates EMI finger shielding in addition to standard shielding, providing enhanced electromagnetic interference rejection suitable for demanding network applications.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538408 be used as a direct replacement for the RJSNEJF84A8 in existing designs?

A: Yes. The RJSAE538408 maintains identical mechanical and electrical interface specifications, including through-hole mounting, 90° right-angle orientation, 8p8c contact configuration, and solder termination. Direct PCB footprint compatibility is confirmed.

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

A: The RJSNEJF84A8 specifies 30.0µin (0.76µm) gold contact finish thickness, while the RJSAE538408 specifies 50.0µin (1.27µm). The increased thickness in the substitute part provides enhanced durability and contact reliability without affecting electrical performance or mechanical fit.

Q: Does the RJSAE538408 operate across the same temperature range as the RJSNEJF84A8?

A: The RJSAE538408 operates across an extended temperature range of -55°C to 85°C, compared to the RJSNEJF84A8 range of -40°C to 85°C. This extended range provides additional operational margin and is fully compatible with applications designed for the original part's temperature specification.

Q: What is the significance of the EMI finger feature in the RJSAE538408?

A: The EMI finger is an additional shielding element that enhances electromagnetic interference rejection. Both parts are shielded; the RJSAE538408 includes this supplementary feature for improved EMI performance in high-noise environments. This enhancement does not affect mechanical compatibility or footprint.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNEJF84A8 and RJSAE538408 are RoHS Compliant and maintain identical Moisture Sensitivity Level (MSL 1, Unlimited), confirming equivalence in environmental and regulatory compliance.

Q: What is the packaging difference between these parts?

A: The RJSNEJF84A8 packaging specification is not provided in the technical data. The RJSAE538408 is supplied in Tray packaging. Confirm packaging requirements with your procurement specifications.

Q: Why is the RJSNEJF84A8 classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on production discontinuation and market transition. The RJSAE538408 represents the active equivalent, ensuring continued supply chain access and regulatory compliance for new designs and procurement cycles.
