RJSNEJ08MA8 Equivalent & Substitute Parts

Part Overview

The RJSNEJ08MA8 is a modular jack connector manufactured by Amphenol ICC (Commercial Products), designed for 8-position 8-contact (8p8c) RJ45 Ethernet applications. This connector features a 90° right-angle orientation, through-hole solder termination, and unshielded construction. The part is classified as obsolete, necessitating identification of active equivalent components to maintain supply chain continuity for new designs and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ08MA8 is determined by strict alignment of 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: Unshielded
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• RoHS Compliance: Yes
• Moisture Sensitivity Level: 1

The RJSAE508708 meets all mandatory matching parameters and qualifies as a direct substitute. Differences in secondary parameters (LED color, contact finish thickness, operating temperature range, and product status) do not affect functional interchangeability in standard 8p8c RJ45 Ethernet jack applications.

Engineering Selection Recommendations

The RJSAE508708 is the qualified substitute for the obsolete RJSNEJ08MA8. Selection of the RJSAE508708 is supported by the following engineering criteria:

Product Status: The RJSAE508708 maintains active production status, ensuring long-term availability and supply chain reliability compared to the obsolete RJSNEJ08MA8.

Compliance Certification: Both parts maintain RoHS compliance and identical Moisture Sensitivity Level (MSL 1), confirming regulatory and environmental compatibility.

Functional Equivalence: All critical electrical and mechanical parameters align precisely, including connector type, contact configuration, orientation, mounting method, termination type, and shielding characteristics.

Enhanced Specifications: The RJSAE508708 provides extended operating temperature range (-55°C to 85°C versus -40°C to 85°C) and increased contact finish thickness (50.0µin versus 30.0µin), offering improved durability and thermal performance.

Additional Features: The RJSAE508708 includes board lock functionality, providing enhanced mechanical retention on PCB assemblies.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE508708 directly replace the RJSNEJ08MA8 in existing designs?

A: Yes. The RJSAE508708 meets all mandatory electrical and mechanical parameters for direct substitution in 8p8c RJ45 Ethernet jack applications. Both parts share identical connector type, contact configuration, orientation, mounting method, termination type, and shielding characteristics.

Q: What is the significance of the different LED colors (Red-Yellow vs. Red-Green)?

A: LED color differences do not affect connector functionality or electrical performance. LED color selection is application-specific and does not impact interchangeability for standard Ethernet jack operations.

Q: Does the increased contact finish thickness on the RJSAE508708 affect compatibility?

A: No. The increased contact finish thickness (50.0µin on RJSAE508708 versus 30.0µin on RJSNEJ08MA8) enhances durability and wear resistance without affecting electrical or mechanical compatibility. This represents an improvement in contact longevity.

Q: Why does the RJSAE508708 have a wider operating temperature range?

A: The RJSAE508708 operates from -55°C to 85°C, compared to the RJSNEJ08MA8 range of -40°C to 85°C. This extended lower temperature limit provides additional thermal margin for applications requiring operation in colder environments. Both parts remain compatible for standard operating conditions.

Q: What is the board lock feature on the RJSAE508708?

A: Board lock is a mechanical retention feature that provides enhanced stability and prevents accidental connector displacement during PCB assembly and field service. This feature does not affect electrical compatibility.

Q: Are there packaging differences between these parts?

A: The RJSNEJ08MA8 packaging is not specified in available documentation. The RJSAE508708 is supplied in tray packaging. Confirm packaging requirements with your procurement specifications.

Q: Is the RJSAE508708 suitable for new design implementations?

A: Yes. The RJSAE508708 is the recommended component for new designs requiring 8p8c RJ45 Ethernet jack connectors with 90° right-angle orientation and through-hole solder termination. Active production status ensures supply continuity.
