Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the RJSNE5381A8 is determined by the following critical parameters:

Mechanical Compatibility:

• Connector type (Jack)
• Connector standard (8p8c RJ45 Ethernet)
• Number of positions and contacts (8 positions, 8 contacts)
• Orientation (90° right angle)
• Mounting type (through hole)
• Tab direction (up and down)

Electrical Compatibility:

• Termination method (solder)
• Shielding configuration (shielded with EMI finger)
• Contact material (phosphor bronze)
• Contact finish (gold plating)

Environmental and Regulatory:

• Operating temperature range
• RoHS compliance status
• Moisture sensitivity level

The substitute part RJSAE5381A8 maintains equivalence across all mechanical and electrical parameters while meeting environmental and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE5381A8 qualifies as a direct substitute for the RJSNE5381A8 based on compliance with regulatory requirements and product availability. Both parts are RoHS compliant and carry an MSL rating of 1 (unlimited moisture sensitivity protection required). The substitute part provides an extended operating temperature range (-55°C to 85°C versus -40°C to 85°C), offering additional thermal margin for demanding applications. The RJSAE5381A8 is currently in active product status, ensuring continued component availability and supply chain continuity compared to the obsolete RJSNE5381A8.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between RJSNE5381A8 and RJSAE5381A8? A: The RJSAE5381A8 is the active successor with an extended operating temperature range (-55°C to 85°C) compared to the RJSNE5381A8 (-40°C to 85°C). All mechanical, electrical, and shielding specifications remain identical.

Q: Are these connectors mechanically interchangeable? A: Yes. Both connectors share identical form factors: 90° right-angle orientation, through-hole mounting, 8p8c RJ45 configuration, and tab direction (up and down). Board layouts designed for one connector accommodate the other without modification.

Q: Can I use the RJSAE5381A8 in applications previously designed for the RJSNE5381A8? A: Yes. The RJSAE5381A8 maintains full compatibility across all mechanical, electrical, and environmental specifications relevant to system operation. The extended temperature range provides additional design margin.

Q: Do both connectors meet the same regulatory and compliance standards? A: Yes. Both parts are RoHS compliant and carry MSL 1 (unlimited) ratings. Both are assigned ECCN EAR99 and HTSUS 8536.69.4040 classifications.

Q: Are there packaging considerations when substituting these connectors? A: The RJSNE5381A8 is supplied without specified packaging, while the RJSAE5381A8 is supplied in tray packaging. This does not affect connector performance or interchangeability in circuit board applications.

Q: What are the contact specifications for both connectors? A: Both connectors feature phosphor bronze contacts with gold plating (50.0µin / 1.27µm thickness) and shielded, EMI finger configurations suitable for standard RJ45 Ethernet applications.
