Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete RJSNEJ38DA8 is based on strict equivalence of the following critical parameters:

Electrical Compatibility:

• Contact configuration: 8p8c (RJ45, Ethernet)
• Shielding type: Shielded with EMI Finger
• Contact material and finish: Phosphor Bronze with Gold plating
• Termination method: Solder

Mechanical Compatibility:

• Mounting type: Through Hole
• Orientation: 90° Angle (Right)
• Housing material: Thermoplastic
• Tab direction: Up and Down

Environmental & Compliance:

• Operating temperature range: Minimum -40°C (substitute supports -55°C, exceeding requirement)
• RoHS compliance: Required
• Moisture sensitivity: MSL 1

The substitute RJSAE538H08 maintains all critical electrical and mechanical parameters while offering active product status and enhanced contact finish thickness (50.0µin vs. 30.0µin), providing improved durability and contact reliability.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538H08 is the direct equivalent substitute for the obsolete RJSNEJ38DA8. Selection is based on the following engineering criteria:

Functional Equivalence: Both connectors are 8p8c RJ45 modular jack connectors with identical electrical contact configurations, shielding architecture, and solder termination specifications. Pin-to-pin compatibility is assured.

Mechanical Interchangeability: Both parts feature identical through-hole mounting, 90° right-angle orientation, and thermoplastic housing with up-and-down tab direction. PCB footprint compatibility is maintained.

Compliance & Certification: Both parts carry RoHS compliance certification and MSL 1 rating, meeting current regulatory requirements for commercial and industrial applications.

Enhanced Reliability: The RJSAE538H08 provides superior contact durability through increased gold plating thickness (50.0µin vs. 30.0µin) and extended operating temperature range (-55°C to 85°C vs. -40°C to 85°C), offering improved performance margins without design modification.

Supply Status: The RJSAE538H08 maintains active product status with current manufacturing support, ensuring long-term availability and consistent quality.

Frequently Asked Questions (FAQ)

Q: Can RJSAE538H08 be used as a direct replacement for RJSNEJ38DA8 without PCB modification?

A: Yes. Both connectors share identical through-hole mounting specifications, 90° right-angle orientation, and footprint dimensions. No PCB layout changes are required.

Q: Are the electrical specifications identical between these two connectors?

A: Yes. Both connectors feature 8p8c RJ45 contact configuration, phosphor bronze contacts with gold finish, EMI shielding, and solder termination. Electrical performance is equivalent.

Q: What is the difference in contact finish thickness, and does it affect compatibility?

A: The RJSAE538H08 provides 50.0µin (1.27µm) gold plating compared to 30.0µin (0.76µm) on the RJSNEJ38DA8. This enhanced thickness improves contact durability and corrosion resistance without affecting electrical or mechanical compatibility.

Q: Does the extended temperature range of RJSAE538H08 (-55°C to 85°C) provide any advantage?

A: The extended lower temperature limit provides additional operational margin for applications in extreme environments. For standard -40°C to 85°C applications, both parts perform equivalently.

Q: Are both connectors RoHS compliant?

A: Yes. Both RJSNEJ38DA8 and RJSAE538H08 are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why is RJSNEJ38DA8 classified as obsolete?

A: Obsolescence reflects Amphenol ICC's product lifecycle management. The RJSAE538H08 represents the current active equivalent in the product line, offering equivalent functionality with enhanced specifications.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes. The RJSAE538H08 is a direct functional and mechanical equivalent. Existing designs using RJSNEJ38DA8 can transition to RJSAE538H08 without design revision.
