RJSNEJ387A8

Part Overview

The RJSNEJ387A8 is a modular jack connector manufactured by Amphenol ICC (Commercial Products) in the RJSNE series. This 8p8c (RJ45, Ethernet) connector features 90° right-angle orientation with shielding and EMI finger protection, designed for through-hole solder termination. The product is currently obsolete, necessitating identification of active substitute components for ongoing system support and new deployments.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJ387A8 is determined by equivalence in the following critical parameters:

Core Functional Parameters:

• Connector Type: Jack
• Contact Configuration: 8p8c (RJ45, Ethernet)
• Mounting Method: Through Hole
• Orientation: 90° Angle (Right)
• Termination Type: Solder
• Shielding: Shielded, EMI Finger

Compliance and Environmental Parameters:

• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)
• Operating Temperature Range capability

The RJSAE538708 maintains functional equivalence across all critical parameters while providing an active product status alternative from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538708 is the direct substitute for the obsolete RJSNEJ387A8. Both components are manufactured by Amphenol ICC (Commercial Products) and maintain RoHS compliance with MSL 1 rating. The RJSAE538708 offers the advantage of active product status, ensuring continued availability and manufacturing support.

The RJSAE538708 provides an extended operating temperature range (-55°C ~ 85°C versus -40°C ~ 85°C) and increased contact finish thickness (50.0µin versus 30.0µin), both representing performance enhancements over the original component. Mechanical and electrical form-factor compatibility is complete, including 8p8c configuration, 90° right-angle orientation, through-hole solder termination, and shielded design with EMI finger.

Frequently Asked Questions (FAQ)

Q: Can RJSAE538708 directly replace RJSNEJ387A8? A: Yes. Both connectors share identical functional specifications for connector type, contact configuration, mounting method, orientation, termination, and shielding. The RJSAE538708 maintains full mechanical and electrical compatibility.

Q: What is the difference in contact finish thickness? A: The RJSAE538708 specifies 50.0µin (1.27µm) gold contact finish compared to 30.0µin (0.76µm) for RJSNEJ387A8. This increased thickness on the substitute part provides enhanced durability and contact longevity without affecting compatibility.

Q: Why is the operating temperature range extended on RJSAE538708? A: The RJSAE538708 supports -55°C to 85°C operation, extending the lower temperature limit by 15°C compared to the RJSNEJ387A8 (-40°C to 85°C). This provides broader environmental operating capability for applications requiring enhanced cold-temperature performance.

Q: Are both parts RoHS compliant? A: Yes. Both RJSNEJ387A8 and RJSAE538708 are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity classification.

Q: What packaging is available for the substitute part? A: RJSAE538708 is supplied in tray packaging, while the original RJSNEJ387A8 packaging specification was not provided in the technical data.

Q: Will PCB footprint and land pattern be compatible between these parts? A: Yes. Both connectors specify identical mounting type (through-hole), pin configuration (8p8c), and orientation (90° right-angle), ensuring footprint compatibility on existing printed circuit board designs.
