RJSNEJ08K08 Equivalent & Substitute Parts

Part Overview

The RJSNEJ08K08 is a modular jack connector manufactured by Amphenol ICC (Commercial Products), designed for 8p8c (RJ45, Ethernet) applications with 90° right-angle orientation and unshielded configuration. This connector features through-hole solder termination and is suitable for network and telecommunications equipment requiring right-angle PCB mounting.

The RJSNEJ08K08 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure continued availability for maintenance, repair, and new production runs where design specifications permit alternative configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJ08K08 is determined by 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
• Number of Ports: 8
• Number of Rows: 2

Allowable Variation Parameters:

• Shielding: The RJSNEJ08K08 is unshielded; shielded variants may substitute where EMI protection is required or acceptable
• Contact Finish Thickness: Variation permitted within gold plating specifications
• Operating Temperature Range: Substitute parts with extended or equivalent ranges are acceptable
• LED Color: Variation permitted based on application requirements
• Tab Direction: Variation permitted based on PCB layout requirements

The RJSAE-5381-08 qualifies as a substitute because it maintains all mandatory matching parameters while introducing shielding and EMI finger protection as an enhanced feature.

Engineering Selection Recommendations

RJSNEJ08K08 Status: The RJSNEJ08K08 is classified as obsolete. New production sourcing from original inventory is limited to 662 pieces currently in stock. For applications requiring long-term component availability and supply chain continuity, transition to active product alternatives is recommended.

RJSAE-5381-08 Selection Criteria: The RJSAE-5381-08 is an active product with 3906 pieces in current inventory, ensuring superior long-term availability. Both parts are RoHS Compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming regulatory and trade compliance equivalence.

Key Differences:

• The RJSAE-5381-08 introduces shielding with EMI finger protection, providing enhanced electromagnetic interference rejection compared to the unshielded RJSNEJ08K08
• The RJSAE-5381-08 features extended operating temperature range (-55°C ~ 85°C) versus the RJSNEJ08K08 (-40°C ~ 85°C)
• The RJSAE-5381-08 includes board lock feature and higher contact finish thickness (50.0µin vs. 30.0µin)
• Packaging differs: RJSNEJ08K08 uses standard packaging; RJSAE-5381-08 uses tray packaging

Substitution Feasibility: The RJSAE-5381-08 is a direct functional substitute for the RJSNEJ08K08 in applications where shielding is acceptable or beneficial. PCB layout compatibility must be verified due to potential dimensional differences introduced by shielding and EMI finger components. The board lock feature of the RJSAE-5381-08 provides additional mechanical retention not present in the RJSNEJ08K08.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE-5381-08 replace the RJSNEJ08K08 in existing designs?

A: The RJSAE-5381-08 maintains identical contact configuration (8p8c RJ45), orientation (90° right-angle), mounting type (through-hole), and termination method (solder). Substitution is feasible provided the PCB layout accommodates the shielded housing dimensions and the application does not prohibit shielding. Physical verification of connector footprint compatibility is required before implementation.

Q: What is the primary difference between these two connectors?

A: The RJSNEJ08K08 is unshielded, while the RJSAE-5381-08 is shielded with EMI finger protection. The RJSAE-5381-08 also features board lock retention, extended temperature range, and higher gold plating thickness. Both maintain identical electrical contact configuration and solder termination.

Q: Why is the RJSNEJ08K08 listed as obsolete?

A: The RJSNEJ08K08 has reached end-of-life status in the manufacturer's product portfolio. The RJSAE-5381-08 represents the active equivalent offering from Amphenol ICC (Commercial Products) with enhanced features and superior long-term availability.

Q: Are there any compliance or regulatory differences between these parts?

A: Both connectors are RoHS Compliant, carry identical ECCN (EAR99) classification, and share the same HTSUS code (8536.69.4040). No regulatory or compliance barriers exist to substitution.

Q: What is the significance of the board lock feature on the RJSAE-5381-08?

A: The board lock feature provides mechanical retention of the connector to the PCB, preventing accidental disconnection during handling or vibration. This feature is absent on the RJSNEJ08K08 and may require PCB design modification if the original design does not accommodate board lock tabs.

Q: Does the shielding on the RJSAE-5381-08 affect electrical performance?

A: Shielding provides EMI rejection and is electrically compatible with standard RJ45 Ethernet applications. The shielded configuration does not degrade electrical performance and enhances noise immunity in environments with electromagnetic interference.

Q: What packaging considerations apply to these connectors?

A: The RJSNEJ08K08 uses standard packaging, while the RJSAE-5381-08 is supplied in tray packaging. Tray packaging is standard for high-volume production and does not affect connector functionality or performance.
