Substitute Part Grouping Explanation

Substitution between RJSNEJ381A8 and RJSAEJ381A8 is valid based on the following criteria:

Matching Parameters:

• Connector Type: Jack
• Contact Configuration: 8p8c (RJ45, Ethernet)
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination Method: Solder
• Shielding: Shielded, EMI Finger
• Contact Material: Phosphor Bronze
• Contact Finish: Gold, 30.0µin (0.76µm)
• Housing Material: Thermoplastic
• RoHS Compliance: Both parts are RoHS Compliant
• MSL Rating: Both rated MSL 1 (Unlimited)

These identical electrical and mechanical parameters establish functional interchangeability for printed circuit board applications.

Parameter Comparison

Engineering Selection Recommendations

The RJSAEJ381A8 is the designated substitute for the obsolete RJSNEJ381A8. Both parts are manufactured by Amphenol ICC and hold RoHS Compliant certification with identical MSL ratings. The substitute maintains all critical electrical and mechanical specifications required for 8p8c RJ45 Ethernet jack applications with right-angle through-hole mounting. The RJSAEJ381A8 offers an extended operating temperature range (-55°C to 85°C versus -40°C to 85°C), providing additional thermal margin in demanding applications. Active product status of the substitute ensures continued availability and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can RJSAEJ381A8 directly replace RJSNEJ381A8 in existing designs? A: Yes. Both connectors share identical electrical characteristics, pinout configuration (8p8c), physical orientation (90° right-angle), mounting method (through-hole solder), and shielding design. Pin-for-pin and mechanical compatibility is established.

Q: What is the difference in operating temperature range? A: RJSNEJ381A8 operates from -40°C to 85°C, while RJSAEJ381A8 extends to -55°C at the lower temperature limit. The upper limit of 85°C is identical. Applications requiring operation below -40°C should use the RJSAEJ381A8.

Q: Are there packaging differences between these parts? A: RJSNEJ381A8 packaging is not specified in the available data. RJSAEJ381A8 is packaged in Trays. Verify packaging requirements for your production workflow.

Q: Do both parts meet RoHS compliance requirements? A: Yes. Both RJSNEJ381A8 and RJSAEJ381A8 are RoHS Compliant with MSL 1 (Unlimited) ratings, suitable for lead-free soldering processes.

Q: Why is RJSNEJ381A8 listed as obsolete? A: Product obsolescence typically indicates end-of-life status. The RJSAEJ381A8 provides functional equivalence for new designs and replacement applications.
