Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJF8508 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Contact Configuration: 8p8c (RJ45, Ethernet)
• Orientation: 90° Angle (Right)
• Mounting Type: Through Hole
• Termination Method: Solder
• Shielding: Shielded
• Housing Material: Thermoplastic
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• RoHS Compliance: RoHS Compliant
• MSL Rating: 1 (Unlimited)

Allowable Variation Parameters:

• Operating Temperature Range: Substitute may extend the range
• Contact Finish Thickness: Substitute may exceed minimum specification
• Product Status: Active status preferred for obsolete parts
• EMI Shielding Enhancement: Additional EMI finger protection permitted

The RJSAE-5385-08 qualifies as a direct substitute based on full alignment with all mandatory parameters and acceptable variations in operating temperature range and contact finish thickness.

Engineering Selection Recommendations

Primary Substitute: RJSAE-5385-08

The RJSAE-5385-08 is the qualified substitute for the obsolete RJSNEJF8508. Selection rationale:

1. Full Parameter Alignment: All mandatory electrical and mechanical parameters match exactly, ensuring direct functional equivalence in 8p8c RJ45 Ethernet jack applications with 90° right-angle through-hole solder termination.

2. Active Product Status: The RJSAE-5385-08 maintains active product status with Amphenol ICC, providing assured long-term availability and supply chain continuity compared to the obsolete RJSNEJF8508.

3. Enhanced Specifications: The substitute offers 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), providing superior performance margins without compromising compatibility.

4. EMI Enhancement: The RJSAE-5385-08 includes EMI finger shielding, providing additional electromagnetic interference protection beyond the base shielded specification of the original part.

5. Regulatory Compliance: Both parts maintain identical RoHS compliance and MSL ratings, ensuring no change in handling, storage, or environmental requirements.

6. Packaging Consideration: The RJSAE-5385-08 is supplied in tray packaging, which may differ from original packaging but does not affect functional performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE-5385-08 be used as a direct replacement for the RJSNEJF8508 in existing designs?

A: Yes. The RJSAE-5385-08 meets all mandatory electrical and mechanical parameters required for direct substitution. No design modifications are necessary. The enhanced specifications (higher contact finish thickness and extended temperature range) provide additional performance margin.

Q: What is the significance of the EMI finger feature in the RJSAE-5385-08?

A: The EMI finger provides additional shielding effectiveness against electromagnetic interference. This enhancement is compatible with applications requiring the base shielded specification and does not introduce incompatibility with existing designs.

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

A: No. The extended range (-55°C to 85°C versus -40°C to 85°C) is a performance enhancement. Applications operating within the original -40°C to 85°C specification remain fully compatible.

Q: Are there any differences in solder termination between the two parts?

A: Both parts use identical solder termination methods. No changes to PCB layout, pad design, or soldering procedures are required.

Q: How does the higher contact finish thickness of the RJSAE-5385-08 impact performance?

A: The increased gold plating thickness (50.0µin versus 30.0µin) enhances contact durability and corrosion resistance, providing extended service life without affecting electrical performance or compatibility.

Q: Is the tray packaging of the RJSAE-5385-08 compatible with existing assembly processes?

A: Tray packaging is standard for high-volume assembly operations. Verify compatibility with your specific assembly equipment and handling procedures. The connector itself is functionally identical regardless of packaging format.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNEJF8508 and RJSAE-5385-08 are RoHS compliant with identical MSL ratings (1 - Unlimited), requiring no changes to material handling or storage protocols.

Q: What is the primary reason for substituting the RJSNEJF8508?

A: The RJSNEJF8508 carries obsolete product status. The RJSAE-5385-08 provides assured availability, active manufacturer support, and enhanced specifications while maintaining full functional compatibility.
