Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ38L08 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Jack modular connector
• Contact configuration: 8p8c (RJ45, Ethernet)
• Orientation: 90° right-angle
• Mounting type: Through hole
• Termination method: Solder
• Shielding: Shielded with EMI finger
• Contact material: Phosphor bronze
• Contact finish: Gold plating
• Housing material: Thermoplastic
• RoHS compliance status

Allowable Variation Parameters:

• Contact finish thickness (provided both meet gold plating specification)
• Operating temperature range (substitute range must encompass or equal the original)
• LED color options
• Board lock features
• Tab direction configuration

The RJSAE538H08 meets all mandatory matching parameters and is classified as an active product, making it a direct functional equivalent for the obsolete RJSNEJ38L08.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538H08 is the direct equivalent substitute for the obsolete RJSNEJ38L08. Selection is based on the following engineering criteria:

Product Status: The RJSNEJ38L08 is classified as obsolete, while the RJSAE538H08 maintains active product status with current manufacturing support from Amphenol ICC (Commercial Products).

Compliance Alignment: Both parts maintain identical RoHS compliance status and Moisture Sensitivity Level (MSL 1), ensuring regulatory and environmental compatibility across supply chain transitions.

Electrical and Mechanical Equivalence: The RJSAE538H08 maintains full functional parity with the RJSNEJ38L08 across all critical parameters: 8p8c (RJ45, Ethernet) configuration, 90° right-angle orientation, through-hole solder termination, shielded EMI design, phosphor bronze contacts with gold finish, and thermoplastic housing.

Enhanced Operating Range: The substitute part provides an extended operating temperature range (-55°C to 85°C versus -40°C to 85°C), offering improved thermal margin for demanding applications.

Contact Finish Enhancement: The RJSAE538H08 features increased gold contact finish thickness (50.0µin versus 30.0µin), providing enhanced durability and contact reliability.

For new designs and production continuity, the RJSAE538H08 is the specified replacement for the RJSNEJ38L08.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538H08 be used as a direct replacement for the RJSNEJ38L08 in existing designs?

A: Yes. The RJSAE538H08 is functionally equivalent across all critical parameters: connector type, contact configuration (8p8c RJ45), orientation (90° right-angle), mounting method (through-hole solder), shielding (EMI finger), contact materials, and housing specifications. No design modifications are required.

Q: What is the primary reason for substitution?

A: The RJSNEJ38L08 is classified as obsolete. The RJSAE538H08 is an active product with current manufacturing support, ensuring long-term supply chain availability.

Q: Are there differences in the contact finish between these parts?

A: Both parts feature gold-plated phosphor bronze contacts. The RJSAE538H08 has a thicker gold finish (50.0µin versus 30.0µin), which enhances contact durability and mating cycle performance.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the RJSNEJ38L08 and RJSAE538H08 are RoHS compliant with Moisture Sensitivity Level 1 (unlimited shelf life). Both carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the operating temperature difference, and does it affect compatibility?

A: The RJSNEJ38L08 operates from -40°C to 85°C, while the RJSAE538H08 operates from -55°C to 85°C. The substitute part's extended lower temperature range is fully compatible and provides additional thermal margin for demanding environments.

Q: Are the LED color options identical?

A: The RJSNEJ38L08 offers green and yellow-red LED options, while the RJSAE538H08 offers green and yellow-green options. LED color selection does not affect electrical or mechanical compatibility.

Q: Is board lock functionality available on both parts?

A: The RJSNEJ38L08 includes board lock functionality. The RJSAE538H08 does not list board lock as a specified feature. Verify board lock requirements for your specific application.

Q: Can these connectors be used interchangeably in PCB layouts?

A: Yes. Both parts share identical mounting specifications (through-hole, 90° right-angle orientation, up and down tab direction), allowing direct PCB footprint compatibility without layout modifications.
