Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJF80A8 is determined by strict equivalence across 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
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• RoHS Compliance: Yes
• Moisture Sensitivity Level: 1

Allowable Variations:

• Contact Finish Thickness: May vary (0.76µm to 1.27µm)
• Operating Temperature Range: May extend (substitute range may be broader)
• Product Status: Active substitutes acceptable for obsolete parts
• Packaging Format: May differ (Tray vs. standard packaging)
• EMI Shielding Enhancement: Additional EMI finger shielding permitted

The RJSAE538008 meets all mandatory matching parameters and qualifies as a direct substitute.

Engineering Selection Recommendations

RJSAE538008 as Primary Substitute:

The RJSAE538008 is the qualified equivalent for RJSNEJF80A8 replacement. Selection rationale is based on the following engineering factors:

1. Functional Equivalence: All mandatory electrical and mechanical parameters match exactly, ensuring direct pin-for-pin and footprint compatibility.

2. Enhanced Specifications: The RJSAE538008 provides superior performance characteristics:

   • Extended operating temperature range (-55°C vs. -40°C minimum)
   • Increased contact finish thickness (50.0µin vs. 30.0µin), improving durability and contact reliability
   • Enhanced EMI shielding with integrated EMI finger for improved electromagnetic interference rejection

3. Active Product Status: RJSAE538008 is classified as active, ensuring long-term availability, ongoing manufacturing support, and supply chain continuity.

4. Regulatory Compliance: Both parts maintain RoHS compliance and identical moisture sensitivity ratings, satisfying environmental and reliability requirements.

5. Manufacturer Continuity: Both components are manufactured by Amphenol ICC (Commercial Products), maintaining design consistency and quality standards.

Frequently Asked Questions (FAQ)

Q: Can RJSAE538008 be used as a direct replacement for RJSNEJF80A8 in existing designs?

A: Yes. The RJSAE538008 maintains identical connector type, contact configuration, orientation, mounting type, termination method, and shielding. PCB footprint and electrical performance are directly compatible. No design modifications are required.

Q: What is the significance of the EMI finger in RJSAE538008?

A: The EMI finger provides enhanced electromagnetic interference shielding. This is an additive feature that improves signal integrity and noise rejection without compromising compatibility with the original design specification.

Q: Does the thicker gold plating on RJSAE538008 affect compatibility?

A: No. The increased contact finish thickness (50.0µin vs. 30.0µin) enhances contact durability and wear resistance. This represents an improvement that does not introduce compatibility issues.

Q: Why is the operating temperature range different?

A: RJSAE538008 specifies an extended minimum operating temperature (-55°C vs. -40°C). This broader range indicates enhanced thermal performance and does not restrict use in applications within the original -40°C ~ 85°C specification.

Q: Are there packaging differences between these parts?

A: RJSNEJF80A8 packaging is not specified in the provided data. RJSAE538008 is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the inventory status for these parts?

A: RJSNEJF80A8 is obsolete with 1070 pcs in stock. RJSAE538008 is active with 771 pcs in stock. For long-term production requirements, RJSAE538008 is the recommended selection due to active product status.

Q: Are both parts RoHS compliant?

A: Yes. Both RJSNEJF80A8 and RJSAE538008 are RoHS compliant with identical moisture sensitivity level (MSL 1 - Unlimited).
