Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEG38DA8 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Shielding: Shielded, EMI Finger
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• RoHS Status: RoHS Compliant
• MSL Rating: 1 (Unlimited)

The RJSAE-5385-08 satisfies all mandatory matching parameters and qualifies as a direct substitute. Both connectors maintain identical mechanical and electrical interface specifications, ensuring PCB-level compatibility and functional equivalence in 8p8c modular jack applications.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE-5385-08 is the qualified substitute for the obsolete RJSNEG38DA8. Selection is based on the following engineering criteria:

Compliance & Regulatory Status: Both parts maintain RoHS compliance and identical MSL ratings (1 - Unlimited), ensuring regulatory equivalence and environmental compatibility across manufacturing and deployment environments.

Product Lifecycle Status: The RJSNEG38DA8 is obsolete, while the RJSAE-5385-08 maintains active product status. Active status ensures ongoing availability, manufacturing support, and supply chain continuity for new production runs and field replacements.

Mechanical & Electrical Equivalence: All critical interface parameters match identically: 8p8c jack configuration, 90° right-angle orientation, through-hole solder termination, shielded EMI construction, and board lock features. PCB footprint and mating interface compatibility are preserved.

Performance Enhancements in Substitute: The RJSAE-5385-08 provides extended operating temperature range (-55°C to 85°C versus -40°C to 85°C) and increased contact finish thickness (50.0µin versus 15.0µin), offering improved durability and thermal performance without compromising original design specifications.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE-5385-08 be used as a direct replacement for RJSNEG38DA8 on existing PCBs?

A: Yes. Both connectors share identical mechanical dimensions, pin configurations, mounting hole patterns, and solder pad layouts. No PCB redesign or layout modification is required for substitution.

Q: What is the difference in contact finish thickness between these parts?

A: The RJSNEG38DA8 has 15.0µin (0.38µm) gold plating, while the RJSAE-5385-08 has 50.0µin (1.27µm) gold plating. The thicker plating on the substitute provides enhanced wear resistance and improved contact durability over extended mating cycles.

Q: Does the wider operating temperature range of RJSAE-5385-08 affect compatibility?

A: No. The extended range (-55°C to 85°C) of the substitute is a performance enhancement that maintains full compatibility with applications designed for the original -40°C to 85°C range. The substitute operates safely across both temperature specifications.

Q: Are there packaging differences between these parts?

A: The RJSNEG38DA8 packaging specification is not provided in the input data. The RJSAE-5385-08 is supplied in Tray packaging. Verify packaging requirements against your procurement and assembly specifications.

Q: Why is the RJSNEG38DA8 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The RJSAE-5385-08 (active status) is the current production equivalent, ensuring long-term supply availability and manufacturing support.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNEG38DA8 and RJSAE-5385-08 are RoHS compliant with MSL rating 1 (Unlimited), meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What is the inventory status for the substitute part?

A: The RJSAE-5385-08 has 771 pieces in new original stock, ensuring immediate availability for design transitions and production requirements.
