Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ38K08 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 RJSAE538EA8 meets all mandatory matching parameters and qualifies as a direct substitute. Both connectors share identical functional specifications for 8p8c modular jack applications with right-angle through-hole solder termination and shielded construction.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538EA8 is the qualified substitute for the obsolete RJSNEJ38K08. Both connectors are manufactured by Amphenol ICC (Commercial Products) and maintain identical electrical and mechanical specifications for 8p8c modular jack applications.

Compliance Status: Both parts are RoHS Compliant with MSL 1 (Unlimited) rating, ensuring compatibility with current manufacturing and environmental standards.

Product Status Advantage: The RJSAE538EA8 carries Active product status, providing assured long-term availability and supply chain support compared to the obsolete RJSNEJ38K08.

Contact Finish Thickness Difference: The RJSAE538EA8 features a gold contact finish thickness of 50.0µin (1.27µm), compared to 30.0µin (0.76µm) on the RJSNEJ38K08. This increased thickness provides enhanced durability and contact reliability.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538EA8 directly replace the RJSNEJ38K08 in existing designs?

A: Yes. Both connectors share identical specifications for connector type, contact count, mounting method, orientation, termination, shielding, contact material, contact finish type, housing material, and compliance certifications. Direct substitution is supported without design modification.

Q: What is the significance of the contact finish thickness difference?

A: The RJSAE538EA8 provides 50.0µin (1.27µm) gold plating compared to 30.0µin (0.76µm) on the RJSNEJ38K08. Increased plating thickness enhances contact durability, wear resistance, and long-term reliability in mating cycles.

Q: Does the extended operating temperature range of the RJSAE538EA8 affect compatibility?

A: No. The RJSAE538EA8 supports -55°C to 85°C, which encompasses the -40°C to 85°C range of the RJSNEJ38K08. This extended range provides additional environmental flexibility without compromising compatibility.

Q: Are both connectors RoHS compliant?

A: Yes. Both the RJSNEJ38K08 and RJSAE538EA8 are RoHS Compliant with MSL 1 (Unlimited) rating, meeting current environmental and manufacturing standards.

Q: Why is the RJSNEJ38K08 classified as obsolete?

A: The RJSNEJ38K08 is listed as obsolete by the manufacturer. The RJSAE538EA8, with Active product status, represents the current production equivalent and is recommended for new designs and ongoing supply requirements.

Q: Are there any LED color differences between these connectors?

A: Yes. The RJSNEJ38K08 features Yellow-Green and Orange LED colors, while the RJSAE538EA8 features Yellow-Green and Yellow LED colors. LED color selection should be verified against specific application requirements.
