Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJ38FA8 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Jack
• Contact configuration: 8p8c (RJ45, Ethernet)
• Orientation: 90° right-angle
• Mounting type: Through hole
• Termination: Solder
• Shielding: Shielded with EMI finger
• Contact material: Phosphor Bronze
• Contact finish: Gold
• Housing material: Thermoplastic
• RoHS compliance: Yes
• Moisture sensitivity level: 1

The RJSAE538EA8 meets all mandatory matching parameters and qualifies as a direct substitute. Both connectors share identical functional specifications for PCB integration, signal integrity, and environmental compliance.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538EA8 is the qualified substitute for the obsolete RJSNEJ38FA8 based on the following engineering criteria:

Functional Equivalence: Both connectors are 8p8c (RJ45, Ethernet) shielded jack connectors with identical mechanical and electrical specifications for through-hole solder termination and 90° right-angle mounting.

Compliance Status: The RJSAE538EA8 maintains RoHS compliance and MSL 1 rating, ensuring compatibility with current manufacturing and environmental standards.

Product Availability: The RJSAE538EA8 holds active product status with 1107 units in stock, providing reliable procurement continuity for the obsolete RJSNEJ38FA8.

Temperature Performance: The RJSAE538EA8 offers an extended operating temperature range (-55°C ~ 85°C) compared to the original part (-40°C ~ 85°C), providing enhanced performance in low-temperature applications.

Contact Finish Thickness: The RJSAE538EA8 features increased gold plating thickness (50.0µin versus 30.0µin), which may provide enhanced durability in high-cycle mating applications.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538EA8 be used as a direct replacement for the RJSNEJ38FA8 in existing designs?

A: Yes. The RJSAE538EA8 meets all mandatory electrical and mechanical specifications for direct substitution. Both connectors share identical contact configuration (8p8c RJ45), orientation (90° right-angle), mounting type (through-hole), termination method (solder), and shielding (EMI finger). No design modifications are required.

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

A: The RJSNEJ38FA8 has a gold contact finish thickness of 30.0µin (0.76µm), while the RJSAE538EA8 has 50.0µin (1.27µm). The thicker plating on the substitute part provides increased contact durability and may extend connector lifespan in applications with frequent mating cycles.

Q: Does the RJSAE538EA8 have a wider operating temperature range?

A: Yes. The RJSAE538EA8 operates from -55°C to 85°C, compared to the RJSNEJ38FA8 range of -40°C to 85°C. This extended low-temperature capability makes the substitute suitable for applications requiring enhanced cold-temperature performance.

Q: Are both connectors RoHS compliant?

A: Yes. Both the RJSNEJ38FA8 and RJSAE538EA8 are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and manufacturing standards.

Q: Why is the RJSNEJ38FA8 listed as obsolete?

A: The RJSNEJ38FA8 is classified as obsolete by the manufacturer. The RJSAE538EA8 is the active equivalent product and should be used for new designs and ongoing procurement.

Q: Are the mechanical dimensions identical between these connectors?

A: Both connectors share identical mechanical specifications for through-hole mounting, 90° right-angle orientation, and tab direction (up and down). They are mechanically interchangeable on PCBs designed for the original RJSNEJ38FA8.
