Key Parameters

Substitute Part Grouping Explanation

The RJSNEJ08408 can be substituted with the RJSAE538408 based on the following critical parameters that define functional and mechanical compatibility:

Core Substitution Criteria:

• Connector Type: Jack (both parts)
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet) (both parts)
• Mounting Type: Through Hole (both parts)
• Orientation: 90° Angle (Right) (both parts)
• Termination: Solder (both parts)
• Contact Material: Phosphor Bronze (both parts)
• Contact Finish: Gold (both parts)
• Housing Material: Thermoplastic (both parts)
• LED Color: Green - Yellow (both parts)
• Tab Direction: Up and Down (both parts)

Key Difference: The primary distinction between these parts is the shielding configuration. The RJSAE538408 features shielded design with EMI finger protection, whereas the RJSNEJ08408 is unshielded. Additionally, the RJSAE538408 includes a Board Lock feature and offers an extended operating temperature range (-55°C ~ 85°C) with thicker gold contact finish (50.0µin versus 30.0µin).

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538408 is the active-status equivalent for the obsolete RJSNEJ08408. Both parts maintain RoHS compliance and MSL Level 1 classification, meeting current regulatory requirements. The RJSAE538408 is recommended for new designs and continued production due to its active product status and ongoing manufacturer support.

The substitution is appropriate for applications where the shielded design and EMI finger protection of the RJSAE538408 are compatible with the circuit board layout and connector mechanical envelope. The extended operating temperature range (-55°C ~ 85°C) of the RJSAE538408 provides improved performance margin in temperature-sensitive applications compared to the original part's -40°C ~ 85°C range.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538408 directly replace the RJSNEJ08408? A: The RJSAE538408 is functionally compatible as a substitute due to matching connector type, pin configuration (8p8c RJ45), mounting method (through hole), orientation (90° right angle), and termination approach (solder). Physical footprints remain identical.

Q: What is the primary functional difference between these connectors? A: The RJSNE series (original part) is unshielded, while the RJSAE series (substitute) includes shielding with an EMI finger. The shielded design provides electromagnetic interference mitigation. The substitute also incorporates a Board Lock feature for improved mechanical retention.

Q: Are there thermal considerations when substituting? A: The RJSAE538408 supports operation at -55°C minimum, compared to -40°C for the RJSNEJ08408. Both support 85°C maximum. Applications operating below -40°C benefit from the extended range of the substitute part.

Q: Does the thicker gold plating on the RJSAE538408 affect compatibility? A: The RJSAE538408 features 50.0µin (1.27µm) gold finish versus 30.0µin (0.76µm) on the RJSNEJ08408. The thicker plating provides enhanced durability and contact reliability without affecting electrical or mechanical compatibility.

Q: Are both parts RoHS compliant? A: Both the RJSNEJ08408 and RJSAE538408 are RoHS compliant and carry MSL Level 1 classification, meeting current environmental and moisture sensitivity standards for production and long-term storage.

Q: What is the current availability status? A: The RJSNEJ08408 is classified as obsolete but has 1194 units in stock. The RJSAE538408 is active with 897 units in stock and represents the manufacturer's current production offering.
