RJSNEJ38CA8 Equivalent & Substitute Parts

Part Overview

The RJSNEJ38CA8 is a shielded modular jack connector featuring 8 positions/8 contacts (RJ45, Ethernet) in a 90° right-angle orientation with through-hole solder termination. This connector incorporates an EMI finger, board lock feature, and dual LED indicators (Red/Green and Green/Yellow options). The part is manufactured by Amphenol ICC (Commercial Products) and operates across a temperature range of -40°C to 85°C.

The RJSNEJ38CA8 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production and field service requirements.

Substitute Part Grouping Explanation

Substitution of the RJSNEJ38CA8 is based on electrical and mechanical parameter equivalence within the modular connector category. The following parameters must align for a part to function as a direct substitute:

Critical 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
• Tab Direction: Up and Down
• Features: Board Lock
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The RJSAE538B08 meets all critical matching parameters and is classified as an active product, making it a functional equivalent for the obsolete RJSNEJ38CA8.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538B08 is the designated substitute for the obsolete RJSNEJ38CA8. Both parts are manufactured by Amphenol ICC (Commercial Products) and maintain identical electrical and mechanical specifications across all critical parameters required for modular connector functionality.

Compliance and Certification: Both parts are RoHS Compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating equivalent environmental handling and regulatory compliance.

Product Status Consideration: The RJSNEJ38CA8 is obsolete, while the RJSAE538B08 is active. The active status of the substitute part ensures ongoing availability and manufacturing support.

Parameter Differences: The RJSAE538B08 features a higher contact finish thickness (50.0µin versus 30.0µin) and an extended lower operating temperature limit (-55°C versus -40°C). These differences represent enhanced performance characteristics that do not compromise compatibility with applications designed for the original part.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538B08 be used as a direct replacement for the RJSNEJ38CA8?

A: Yes. The RJSAE538B08 meets all critical electrical and mechanical parameters required for substitution, including connector type, contact configuration, mounting method, orientation, termination, shielding, and material specifications.

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

A: The RJSNEJ38CA8 has a contact finish thickness of 30.0µin (0.76µm), while the RJSAE538B08 has 50.0µin (1.27µm). The increased thickness in the substitute part provides enhanced durability and contact reliability without affecting electrical performance or mechanical compatibility.

Q: Are there temperature range differences?

A: Yes. The RJSNEJ38CA8 operates from -40°C to 85°C, while the RJSAE538B08 operates from -55°C to 85°C. The substitute part supports a wider lower temperature range, making it suitable for applications requiring extended cold-temperature operation.

Q: Do both parts have the same LED color options?

A: No. The RJSNEJ38CA8 offers Red/Green and Green/Yellow LED options, while the RJSAE538B08 offers Red/Green and Red/Green LED options. LED color selection should be verified against specific application requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNEJ38CA8 and RJSAE538B08 are RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited), meeting equivalent environmental and regulatory standards.

Q: What is the packaging difference?

A: The RJSNEJ38CA8 packaging is not specified in the available data. The RJSAE538B08 is supplied in Tray packaging. Packaging specifications should be confirmed with the supplier for procurement and handling requirements.

Q: Why is the RJSNEJ38CA8 obsolete?

A: The RJSNEJ38CA8 is classified as obsolete. The RJSAE538B08, as an active product from the same manufacturer, provides continued access to equivalent connector functionality and ensures long-term component availability.
