Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJ38308 is based on strict equivalence across the following critical parameters:

• Connector Type & Configuration: Both parts are jack modular connectors with 8p8c (RJ45/Ethernet) contact arrangement
• Orientation & Mounting: Both feature 90° right-angle orientation with through-hole solder termination
• Shielding & EMI Protection: Both include shielded construction with EMI finger
• Electrical Properties: Both use phosphor bronze contacts with gold finish and operate across overlapping temperature ranges
• Compliance & Environmental: Both are RoHS compliant with MSL 1 rating

The RJSAE538608 qualifies as a direct substitute based on these parameters. Differences in contact finish thickness (50.0µin vs. 30.0µin) and extended lower operating temperature limit (-55°C vs. -40°C) represent enhanced specifications that maintain backward compatibility.

Engineering Selection Recommendations

The RJSAE538608 is the qualified substitute for the obsolete RJSNEJ38308. Selection of this substitute is based on the following engineering criteria:

Product Status: The RJSNEJ38308 is classified as obsolete, while the RJSAE538608 maintains active production status, ensuring long-term availability and supply chain continuity.

Electrical & Mechanical Equivalence: Both connectors meet identical specifications for contact configuration, orientation, mounting, termination, and shielding. The 8p8c (RJ45/Ethernet) standard is maintained across both parts.

Compliance & Certifications: Both parts are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, ensuring regulatory alignment.

Enhanced Specifications: The RJSAE538608 provides increased contact finish thickness (50.0µin vs. 30.0µin) and extended lower operating temperature capability (-55°C vs. -40°C), representing performance enhancements that do not compromise backward compatibility.

Environmental Rating: Both parts maintain MSL 1 (Unlimited) moisture sensitivity level, indicating equivalent environmental robustness.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538608 be used as a direct replacement for the RJSNEJ38308 in existing designs?

A: Yes. The RJSAE538608 is electrically and mechanically equivalent to the RJSNEJ38308 across all critical parameters including contact configuration, orientation, mounting type, termination method, and shielding. The substitute maintains identical pinout and physical form factor compatibility.

Q: What is the significance of the difference in contact finish thickness?

A: The RJSAE538608 features 50.0µin (1.27µm) gold plating compared to 30.0µin (0.76µm) on the RJSNEJ38308. This increased thickness provides enhanced durability and contact reliability, particularly in high-cycle mating applications. This represents an improvement over the original specification.

Q: Does the extended operating temperature range of the RJSAE538608 affect compatibility?

A: No. The RJSAE538608 operates from -55°C to 85°C, which encompasses the original -40°C to 85°C range of the RJSNEJ38308. This extended capability ensures the substitute functions across all conditions specified for the original part and beyond.

Q: Are there packaging differences between these parts?

A: The RJSNEJ38308 packaging specification is not provided in the available data. The RJSAE538608 is supplied in tray packaging. Packaging differences do not affect electrical or mechanical compatibility; they relate only to handling and storage logistics.

Q: What is the basis for substitution compatibility?

A: Substitution is based on strict equivalence across connector type, contact configuration (8p8c RJ45), orientation (90° right-angle), mounting method (through-hole solder), shielding (EMI finger), contact materials (phosphor bronze with gold finish), housing material (thermoplastic), and compliance certifications (RoHS, MSL 1). All critical parameters match between the two parts.

Q: Why is the RJSNEJ38308 classified as obsolete?

A: Product obsolescence is determined by the manufacturer. The RJSAE538608, as an active production part from the same manufacturer with equivalent specifications, serves as the current production alternative for new designs and ongoing supply requirements.
