Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ38B08 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Contact configuration: 8p8c (RJ45, Ethernet)
• Orientation: 90° Angle (Right)
• Mounting type: Through Hole
• Termination method: Solder
• Shielding: Shielded with EMI Finger
• Contact material: Phosphor Bronze
• Contact finish: Gold
• Housing material: Thermoplastic
• Number of ports: 8
• Number of rows: 2

Allowable Variations:

• Product status (Obsolete to Active)
• Contact finish thickness (within gold plating specifications)
• Operating temperature range (provided minimum operating temperature does not fall below -40°C)
• Packaging format

The RJSAE538B08 meets all mandatory matching parameters and represents a direct functional equivalent with enhanced specifications in contact finish thickness and extended low-temperature operating range.

Engineering Selection Recommendations

RJSAE538B08 as Primary Substitute:

The RJSAE538B08 is the direct equivalent for the obsolete RJSNEJ38B08. Both connectors are manufactured by Amphenol ICC (Commercial Products) and share identical functional specifications across all critical parameters: 8p8c (RJ45, Ethernet) configuration, 90° right-angle orientation, through-hole solder termination, shielded construction with EMI finger, and board lock functionality.

The RJSAE538B08 offers two technical enhancements over the original part:

1. Contact Finish Thickness: Increased from 30.0µin (0.76µm) to 50.0µin (1.27µm), providing enhanced durability and contact reliability.

2. Operating Temperature Range: Extended from -40°C to 85°C to -55°C to 85°C, supporting broader environmental applications.

Both parts maintain RoHS compliance and MSL 1 (Unlimited) moisture sensitivity rating. The RJSAE538B08 is currently in active production status, ensuring supply chain availability and long-term support.

Frequently Asked Questions (FAQ)

Q: Can RJSAE538B08 be used as a direct replacement for RJSNEJ38B08 in existing designs?

A: Yes. The RJSAE538B08 is functionally equivalent across all critical parameters: contact configuration, orientation, mounting type, termination method, shielding, and contact materials. The enhanced contact finish thickness and extended operating temperature range represent improvements that do not compromise backward compatibility.

Q: What is the difference in contact finish thickness between these parts?

A: The RJSNEJ38B08 has a contact finish thickness of 30.0µin (0.76µm), while the RJSAE538B08 has 50.0µin (1.27µm). The thicker gold plating on the substitute part provides increased wear resistance and improved contact longevity.

Q: Does the extended operating temperature range of RJSAE538B08 affect compatibility?

A: No. The RJSAE538B08 operates from -55°C to 85°C, which encompasses the original part's range of -40°C to 85°C. This extended range provides additional flexibility for applications requiring lower temperature operation without affecting existing designs.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNEJ38B08 and RJSAE538B08 are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What packaging is available for the substitute part?

A: The RJSAE538B08 is supplied in Tray packaging, suitable for automated assembly and component handling processes.

Q: Why is the original RJSNEJ38B08 marked as obsolete?

A: The RJSNEJ38B08 has been superseded by the RJSAE538B08 in Amphenol ICC's product portfolio. The newer part offers enhanced specifications while maintaining full functional equivalence, making it the recommended choice for new designs and ongoing production.
