RJSNEJ08E08 Equivalent & Substitute Parts

Part Overview

The RJSNEJ08E08 is a modular jack connector manufactured by Amphenol ICC (Commercial Products) designed for 8-position 8-contact (8p8c) RJ45 Ethernet applications. This unshielded, right-angle through-hole connector features solder termination and operates across the temperature range of -40°C to 85°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility while offering current product availability and support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJ08E08 is based on strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Number of Ports: 8
• Number of Rows: 2
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• Tab Direction: Up and Down
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variations:

• Shielding: The main part is unshielded; substitutes may include shielded variants with EMI fingers for enhanced electromagnetic interference protection
• Contact Finish Thickness: Variations within gold plating specifications are acceptable
• Operating Temperature Range: Substitutes with extended lower temperature limits are acceptable
• Product Status: Active substitutes are preferred for obsolete parts

The RJSAE538EA8 qualifies as a substitute based on these criteria, offering the same core 8p8c RJ45 jack configuration with right-angle through-hole solder termination, while providing enhanced shielding and active product status.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538EA8 is the qualified substitute for the obsolete RJSNEJ08E08. Both parts maintain identical core specifications for 8p8c RJ45 Ethernet jack connectors with right-angle through-hole solder termination. The RJSAE538EA8 is currently active in production, ensuring ongoing availability and manufacturer support.

The primary difference between the two parts is the addition of shielding with EMI fingers in the RJSAE538EA8. This enhancement provides electromagnetic interference protection without compromising mechanical or electrical compatibility. The substitute also features increased contact finish thickness (50.0µin versus 30.0µin) and an extended lower operating temperature limit (-55°C versus -40°C), both of which represent improvements over the original specification.

Both parts carry RoHS compliance certification and MSL 1 rating, confirming suitability for standard manufacturing and storage conditions. The RJSAE538EA8 is recommended for new designs and as a direct replacement in existing applications where the original RJSNEJ08E08 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538EA8 be used as a direct replacement for the RJSNEJ08E08?

A: Yes. Both connectors share identical core specifications: 8p8c RJ45 jack configuration, right-angle through-hole mounting, solder termination, phosphor bronze contacts with gold finish, and thermoplastic housing. The RJSAE538EA8 includes shielding with EMI fingers, which provides additional electromagnetic interference protection without affecting mechanical or electrical compatibility.

Q: What is the difference in shielding between these two parts?

A: The RJSNEJ08E08 is unshielded, while the RJSAE538EA8 includes shielding with EMI fingers. Shielding reduces electromagnetic interference susceptibility, making the RJSAE538EA8 suitable for applications requiring enhanced EMI protection. Both parts maintain the same contact configuration and termination method.

Q: Are there differences in contact finish specifications?

A: Yes. The RJSNEJ08E08 has a contact finish thickness of 30.0µin (0.76µm), while the RJSAE538EA8 has 50.0µin (1.27µm). The increased thickness in the substitute provides enhanced durability and contact reliability without affecting electrical performance or compatibility.

Q: What is the operating temperature range for each part?

A: The RJSNEJ08E08 operates from -40°C to 85°C. The RJSAE538EA8 operates from -55°C to 85°C. The substitute's extended lower temperature limit provides greater operational flexibility for applications in cold environments.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNEJ08E08 and RJSAE538EA8 are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, confirming compliance with environmental regulations and standard manufacturing storage requirements.

Q: Will the RJSAE538EA8 fit in the same PCB footprint as the RJSNEJ08E08?

A: Yes. Both connectors share identical mounting specifications: through-hole mounting type, 90° right-angle orientation, and up-and-down tab direction. The physical footprint and PCB layout compatibility are maintained between the two parts.

Q: Why is the RJSNEJ08E08 listed as obsolete?

A: The RJSNEJ08E08 has been discontinued by the manufacturer. The RJSAE538EA8 represents the active equivalent in the Amphenol ICC product line, offering the same core functionality with additional features such as shielding and improved contact specifications.
