Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ389A8 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Contact Configuration: 8p8c (RJ45, Ethernet)
• Number of Ports: 8
• Number of Rows: 2
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination Method: Solder
• Shielding: Shielded, EMI Finger
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic

Allowable Variation Parameters:

• Contact Finish Thickness: Variation permitted within industry tolerance
• Operating Temperature Range: Substitute range must encompass or exceed the original specification
• Product Status: Active status preferred for ongoing availability
• Packaging Format: May differ from original specification

The RJSAE538908 meets all mandatory matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538908 is a direct functional equivalent to the RJSNEJ389A8 for applications requiring 8p8c modular jack connectors with right-angle orientation and shielding.

Selection Basis:

The RJSAE538908 maintains identical electrical and mechanical specifications across all critical parameters. The substitute part carries active product status, ensuring ongoing availability and supply chain support. Both parts are RoHS compliant and share identical ECCN and HTSUS classifications, supporting regulatory and trade compliance requirements.

The RJSAE538908 provides an extended operating temperature range (-55°C ~ 85°C) compared to the original part (-40°C ~ 85°C), offering enhanced performance in low-temperature environments. The increased contact finish thickness (50.0µin versus 30.0µin) provides additional durability and contact reliability.

Packaging differs between the two parts; the RJSAE538908 is supplied in tray format, which may require adjustment to receiving and inventory procedures.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538908 be used as a direct replacement for the RJSNEJ389A8 in existing designs?

A: Yes. The RJSAE538908 matches all mandatory electrical and mechanical parameters, including connector type, contact configuration, mounting type, orientation, termination method, and shielding. No design modifications are required.

Q: What is the significance of the contact finish thickness difference?

A: The RJSAE538908 features 50.0µin (1.27µm) gold plating compared to 30.0µin (0.76µm) on the original part. This increased thickness enhances contact durability and corrosion resistance, supporting extended service life in demanding applications.

Q: Does the extended operating temperature range of the RJSAE538908 affect compatibility?

A: No. The substitute part's operating range (-55°C ~ 85°C) encompasses the original specification (-40°C ~ 85°C). This represents an improvement in environmental performance without introducing compatibility issues.

Q: How does packaging format affect part selection?

A: The RJSNEJ389A8 packaging format is not specified in available data. The RJSAE538908 is supplied in tray packaging. Verify that tray packaging accommodates your receiving, storage, and assembly processes. Contact your supplier for alternative packaging options if required.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the RJSNEJ389A8 and RJSAE538908 are RoHS compliant and classified under ECCN EAR99 and HTSUS 8536.69.4040, supporting regulatory and trade compliance.

Q: Why is the RJSNEJ389A8 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The RJSAE538908 carries active status, ensuring continued availability and manufacturing support for new designs and production requirements.
