Substitute Part Grouping Explanation

Substitution of the obsolete RJSNEJ38AC8 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part RJSAEJ38AC8 maintains identical specifications in the following key areas:

Electrical Compatibility:

• 8p8c (RJ45, Ethernet) contact configuration
• Phosphor bronze contact material with 30.0µin gold finish
• Shielded design with EMI finger protection
• Operating temperature range of -55°C to 85°C

Mechanical Compatibility:

• Through-hole solder termination
• 90° right-angle orientation
• Two-row contact arrangement
• Thermoplastic housing material
• Up and down tab direction

Regulatory Compliance:

• RoHS compliant status
• MSL 1 (Unlimited) moisture sensitivity rating
• Identical ECCN and HTSUS classifications

The substitute part differs only in product status (active versus obsolete) and packaging configuration (tray versus unspecified), with no impact on functional or physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RJSAEJ38AC8 is the direct equivalent substitute for the obsolete RJSNEJ38AC8. Selection of this substitute part is supported by the following engineering criteria:

Functional Equivalence: All electrical and mechanical parameters are identical, ensuring direct compatibility in existing circuit designs and PCB layouts without modification.

Regulatory Compliance: Both parts maintain RoHS compliance and identical ECCN/HTSUS classifications, satisfying regulatory requirements for procurement and deployment.

Product Status: The substitute part maintains active product status with Amphenol ICC (Commercial Products), ensuring continued availability and supply chain reliability. The main part's obsolete status necessitates transition to the active equivalent.

Packaging Consideration: The substitute part is supplied in tray packaging, which is standard for production environments and does not affect functional performance or electrical characteristics.

Availability: The substitute part has confirmed inventory of 994 pieces in new original condition, supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can RJSAEJ38AC8 be used as a direct replacement for RJSNEJ38AC8 in existing designs?

A: Yes. The RJSAEJ38AC8 maintains identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, orientation, termination method, shielding, contact materials, and operating temperature range. No design modifications are required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (RJSNEJ38AC8 is obsolete; RJSAEJ38AC8 is active) and packaging (tray for the substitute). All functional and physical characteristics are identical.

Q: Are there any compatibility concerns with PCB footprints or mounting?

A: No. Both parts feature identical through-hole mounting configuration, 90° right-angle orientation, and two-row contact arrangement. PCB footprints and mounting requirements are identical.

Q: Does the tray packaging affect the connector's performance?

A: No. Packaging format does not affect electrical or mechanical performance. Tray packaging is standard for production environments and provides equivalent protection during storage and handling.

Q: Are both parts RoHS compliant?

A: Yes. Both RJSNEJ38AC8 and RJSAEJ38AC8 are RoHS compliant with identical MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the contact finish specification for these connectors?

A: Both parts feature gold-plated phosphor bronze contacts with a finish thickness of 30.0µin (0.76µm), ensuring consistent electrical performance and corrosion resistance.

Q: Can these connectors operate across the full temperature range specified?

A: Yes. Both parts are rated for continuous operation from -55°C to 85°C, supporting deployment in standard industrial and commercial environments.
