Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJ38KA8 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

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

The RJSAE538EA8 meets all mandatory matching parameters and qualifies as a direct substitute. Both connectors share identical mechanical and electrical interface specifications, ensuring functional compatibility in applications originally designed for the RJSNEJ38KA8.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538EA8 is the qualified substitute for the obsolete RJSNEJ38KA8. Selection of this substitute is supported by the following factors:

Product Status: The RJSAE538EA8 carries an active product status, ensuring ongoing availability and manufacturing support. The RJSNEJ38KA8 is obsolete and no longer in production.

Compliance Certifications: Both connectors maintain RoHS compliance and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming regulatory equivalence.

Mechanical and Electrical Interface: The RJSAE538EA8 maintains identical connector geometry, pin configuration, and shielding architecture. Through-hole solder termination and board lock features are preserved.

Operating Conditions: The RJSAE538EA8 extends the lower operating temperature limit to -55°C, providing enhanced thermal performance compared to the original -40°C specification. The upper temperature limit remains at 85°C.

Contact Finish Durability: The RJSAE538EA8 features a gold contact finish thickness of 50.0µin (1.27µm), compared to 30.0µin (0.76µm) on the original part. This increased thickness provides enhanced contact durability and wear resistance.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538EA8 be used as a direct replacement for the RJSNEJ38KA8 in existing designs?

A: Yes. The RJSAE538EA8 meets all mandatory mechanical and electrical interface specifications. Both connectors feature identical 8p8c (RJ45, Ethernet) pin configurations, 90° right-angle orientation, through-hole solder termination, and shielded EMI finger design. No design modifications are required.

Q: What are the differences between these two connectors?

A: The primary differences are product status, operating temperature range, and contact finish thickness. The RJSAE538EA8 is an active product with an extended lower operating temperature of -55°C (versus -40°C) and a thicker gold contact finish of 50.0µin compared to 30.0µin on the original part.

Q: Are both connectors RoHS compliant?

A: Yes. Both the RJSNEJ38KA8 and RJSAE538EA8 are RoHS compliant and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4040).

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors carry a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Are the LED color indicators the same on both connectors?

A: The LED color indicators differ. The RJSNEJ38KA8 features Yellow-Green and Orange LEDs, while the RJSAE538EA8 features Yellow-Green and Yellow LEDs. LED color selection should be verified against application requirements.

Q: What is the inventory status for these parts?

A: The RJSNEJ38KA8 has 641 pieces in stock as new original inventory. The RJSAE538EA8 has 1,107 pieces in stock as new original inventory. Availability of the substitute part is higher due to its active product status.
