Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJ08B08 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Orientation: 90° Angle (Right)
• Mounting Type: Through Hole
• Termination: Solder
• Shielding: Unshielded
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• RoHS Compliance: Yes
• Moisture Sensitivity Level: 1 (Unlimited)

The RJSAE508B08 satisfies all mandatory matching parameters and is classified as an active product, making it a direct functional equivalent for the obsolete RJSNEJ08B08.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE508B08 is the direct substitute for the obsolete RJSNEJ08B08. Both connectors are manufactured by Amphenol ICC (Commercial Products) and maintain identical electrical and mechanical specifications across all critical parameters. The RJSAE508B08 is currently in active production status with 983 units in stock, ensuring component availability.

Key distinctions between the parts are:

Contact Finish Thickness: The RJSAE508B08 provides increased gold plating thickness (50.0µin versus 30.0µin), which enhances contact durability and corrosion resistance.

Operating Temperature Range: The RJSAE508B08 extends the lower operating temperature limit to -55°C compared to -40°C for the RJSNEJ08B08, providing broader environmental compatibility.

Additional Feature: The RJSAE508B08 includes a Board Lock feature not present in the RJSNEJ08B08.

Packaging: The RJSAE508B08 is supplied in Tray packaging, whereas the RJSNEJ08B08 packaging specification is not provided.

Both parts maintain RoHS compliance and identical export classification (EAR99) and tariff codes (HTSUS 8536.69.4040).

Frequently Asked Questions (FAQ)

Q: Can the RJSAE508B08 be used as a direct replacement for the RJSNEJ08B08?

A: Yes. The RJSAE508B08 meets all mandatory electrical and mechanical specifications required for functional equivalence. Both connectors are 8p8c RJ45 Ethernet jacks with 90° right-angle orientation, through-hole solder termination, unshielded construction, and identical contact materials and finishes.

Q: What is the significance of the increased contact finish thickness in the RJSAE508B08?

A: The RJSAE508B08 provides 50.0µin (1.27µm) gold plating compared to 30.0µin (0.76µm) in the RJSNEJ08B08. This increased thickness improves contact durability and extends the service life of the connector in applications with frequent mating cycles.

Q: Does the Board Lock feature on the RJSAE508B08 affect mechanical compatibility?

A: The Board Lock feature is an additional mechanical enhancement that provides improved retention on the printed circuit board. This feature does not compromise compatibility with existing designs and provides enhanced mechanical stability.

Q: Are there temperature range differences between these connectors?

A: The RJSAE508B08 operates from -55°C to 85°C, while the RJSNEJ08B08 operates from -40°C to 85°C. The RJSAE508B08 supports a wider lower temperature range, making it suitable for applications requiring extended cold-temperature operation.

Q: What is the packaging difference between these parts?

A: The RJSAE508B08 is supplied in Tray packaging. The RJSNEJ08B08 packaging specification is not documented in the available technical data.

Q: Are both connectors RoHS compliant?

A: Yes. Both the RJSNEJ08B08 and RJSAE508B08 are RoHS compliant and carry identical export classification (EAR99) and tariff codes (HTSUS 8536.69.4040).

Q: What is the current availability status of these parts?

A: The RJSNEJ08B08 is obsolete with 801 units in stock. The RJSAE508B08 is active in production with 983 units in stock, ensuring long-term component availability.
