Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNE5F8KA8 is based on strict equivalence of the following electrical and mechanical parameters:

• Connector Type: Jack configuration with 8p8c (RJ45/Ethernet) contact arrangement
• Mounting Configuration: Through-hole solder termination with 90° right-angle orientation
• Shielding: Shielded design with equivalent EMI protection
• Contact Specifications: Phosphor bronze material with gold plating (50.0µin thickness)
• Environmental Rating: Operating temperature range compatibility
• Compliance: RoHS compliance and moisture sensitivity level (MSL 1)

The RJSAE-5381-08 meets all critical substitution criteria, maintaining functional and mechanical equivalence with the obsolete RJSNE5F8KA8 while offering active product status and improved long-term availability.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE-5381-08 is the primary substitute for the obsolete RJSNE5F8KA8. Both components are RoHS compliant and maintain equivalent moisture sensitivity levels, ensuring regulatory and environmental compatibility. The RJSAE-5381-08 features active product status with documented long-term availability, supporting sustained procurement and system support operations. The extended operating temperature range (-55°C to +85°C) on the substitute provides additional thermal margin compared to the original part (-40°C to +85°C). Enhanced EMI shielding through the integrated EMI finger on the RJSAE-5381-08 offers improved electromagnetic interference rejection without compromising mechanical or electrical equivalence. Both components utilize identical contact materials, finishes, and contact finish thicknesses, ensuring signal integrity and reliability characteristics remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE-5381-08 be directly substituted for the RJSNE5F8KA8 in existing designs? A: Yes. Both connectors share identical electrical and mechanical specifications including connector type, contact arrangement (8p8c RJ45), mounting method (through-hole solder), orientation (90° right-angle), shielding configuration, contact materials, and finish specifications. No design modifications are required.

Q: What is the significance of the EMI finger feature on the RJSAE-5381-08? A: The EMI finger provides additional electromagnetic shielding through direct contact with the mating connector's shielded plug. This enhances EMI rejection performance while maintaining full mechanical and electrical compatibility with standard RJ45 connections.

Q: Does the extended operating temperature range of the RJSAE-5381-08 affect substitution decisions? A: No. The RJSAE-5381-08 supports a wider operating range (-55°C to +85°C) compared to the original RJSNE5F8KA8 (-40°C to +85°C). This extended range is a performance enhancement that does not prevent substitution in applications originally designed for the narrower range.

Q: Are packaging differences between these parts significant? A: The RJSNE5F8KA8 packaging specification is undeclared, while the RJSAE-5381-08 ships in trays. This is a supply-chain consideration only and does not affect functional or mechanical compatibility.

Q: Do both parts maintain equivalent RoHS compliance and moisture sensitivity ratings? A: Yes. Both the RJSNE5F8KA8 and RJSAE-5381-08 are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity, ensuring equivalent environmental handling and regulatory status.
