RJSNEJ080A8 Equivalent & Substitute Parts

Part Overview

The RJSNEJ080A8 is a Jack Modular Connector featuring 8p8c (RJ45, Ethernet) configuration with 90° right-angle orientation and unshielded design. Manufactured by Amphenol ICC (Commercial Products), this through-hole solder-terminated connector is designed for standard Ethernet applications requiring board-level integration.

The RJSNEJ080A8 carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance where this connector type remains in use.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ080A8 is determined by the following critical parameters:

Core Compatibility Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• 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
• Features: Board Lock

Allowable Variation Parameters:

• Shielding: Unshielded or Shielded configurations are functionally compatible at the mechanical and electrical interface level
• Contact Finish Thickness: Variation within gold plating specifications
• Operating Temperature Range: Extended ranges are acceptable for substitution
• Product Status: Active status preferred for new designs; Obsolete status acceptable for legacy support

The RJSAE538008 qualifies as a substitute part based on matching all core compatibility parameters while introducing shielded design with EMI finger protection and extended operating temperature range.

Engineering Selection Recommendations

For Legacy System Maintenance: The RJSNEJ080A8 remains suitable for applications where existing designs are locked and component replacement is required for repair or refurbishment. Current inventory of 1018 pieces supports near-term availability.

For New Designs and Long-Term Supply: The RJSAE538008 is the recommended selection. This part maintains identical mechanical and electrical interface compatibility while offering:

• Active product status ensuring long-term availability and manufacturing support
• Shielded design with EMI finger protection for improved signal integrity in noise-sensitive environments
• Extended operating temperature range (-55°C to 85°C) providing broader environmental compatibility
• Increased contact finish thickness (50.0µin vs. 30.0µin) for enhanced durability and contact reliability
• RoHS compliance and MSL 1 rating matching the original part

Both parts are manufactured by Amphenol ICC (Commercial Products) and carry identical RoHS and MSL certifications, ensuring regulatory and environmental compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can RJSAE538008 be used as a direct replacement for RJSNEJ080A8 in existing PCB designs?

A: Yes. Both connectors share identical mechanical footprints, mounting hole patterns, and solder pad configurations for through-hole termination. The 90° right-angle orientation, board lock feature, and tab direction (up and down) are identical. PCB layout modifications are not required.

Q: What is the primary functional difference between these two parts?

A: The RJSAE538008 incorporates shielding with an EMI finger, whereas the RJSNEJ080A8 is unshielded. This difference provides electromagnetic interference rejection in the substitute part. Both parts maintain identical 8p8c (RJ45, Ethernet) electrical connectivity and contact specifications.

Q: Are there compatibility concerns with the increased contact finish thickness in RJSAE538008?

A: No. The increased gold plating thickness (50.0µin vs. 30.0µin) in the substitute part enhances contact durability and wear resistance without affecting electrical performance or mating compatibility. This represents an improvement in long-term reliability.

Q: Why is RJSNEJ080A8 marked as Obsolete?

A: Obsolete status indicates that Amphenol ICC (Commercial Products) has discontinued active manufacturing and support for this part number. The RJSAE538008 represents the current active equivalent in the product line.

Q: What is the impact of the extended operating temperature range in RJSAE538008?

A: The RJSAE538008 operates from -55°C to 85°C compared to -40°C to 85°C for the RJSNEJ080A8. This extended lower temperature limit provides compatibility with applications requiring operation in colder environments. For applications within the original -40°C to 85°C range, both parts perform identically.

Q: Are both parts RoHS compliant?

A: Yes. Both RJSNEJ080A8 and RJSAE538008 carry RoHS Compliant status and MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent regulatory and environmental compliance.

Q: What packaging differences exist between these parts?

A: The RJSNEJ080A8 packaging specification is not detailed in available data. The RJSAE538008 is supplied in Tray packaging. Confirm packaging requirements with your procurement specification before ordering.
