Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJF8108 is determined by strict alignment of the following critical parameters:

• Connector type: Jack
• Contact configuration: 8p8c (RJ45, Ethernet)
• Orientation: 90° right-angle
• Mounting method: Through hole
• Termination method: Solder
• Shielding: Shielded construction
• Contact material: Phosphor bronze
• Contact finish: Gold plating
• Housing material: Thermoplastic
• RoHS compliance: Required
• Moisture sensitivity level: 1 (Unlimited)

The RJSAE-5381-08 meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete RJSNEJF8108.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE-5381-08 is the appropriate substitute for the obsolete RJSNEJF8108. Both connectors are manufactured by Amphenol ICC and maintain identical functional specifications for jack connector type, 8p8c contact configuration, 90° right-angle orientation, through-hole mounting, and solder termination.

Key differentiators supporting substitution:

• The RJSAE-5381-08 is an active product with current manufacturing support, whereas the RJSNEJF8108 is obsolete.
• Both connectors are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.
• The RJSAE-5381-08 features enhanced EMI shielding with an EMI finger, providing improved electromagnetic interference protection compared to the base shielded design of the RJSNEJF8108.
• The RJSAE-5381-08 offers an extended operating temperature range (-55°C to 85°C) compared to the RJSNEJF8108 (-40°C to 85°C), providing greater thermal margin.
• Contact finish thickness on the RJSAE-5381-08 is 50.0µin (1.27µm) versus 30.0µin (0.76µm) on the RJSNEJF8108, offering enhanced contact durability and wear resistance.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE-5381-08 be used as a direct replacement for the RJSNEJF8108 in existing designs?

A: Yes. Both connectors share identical connector type, contact configuration, orientation, mounting method, and termination specifications. The RJSAE-5381-08 is functionally compatible and can be substituted without design modification.

Q: What is the difference in shielding between these two connectors?

A: The RJSNEJF8108 provides standard shielding. The RJSAE-5381-08 includes shielding with an EMI finger, which provides additional electromagnetic interference suppression. This enhancement does not affect mechanical or electrical compatibility.

Q: Why does the RJSAE-5381-08 have a thicker gold contact finish?

A: The increased contact finish thickness (50.0µin versus 30.0µin) on the RJSAE-5381-08 enhances contact durability, reduces wear during mating cycles, and extends connector service life. This is a performance improvement that maintains full compatibility.

Q: What is the significance of the extended operating temperature range on the RJSAE-5381-08?

A: The RJSAE-5381-08 operates from -55°C to 85°C, compared to -40°C to 85°C for the RJSNEJF8108. This extended lower temperature limit provides additional thermal margin for applications requiring operation in colder environments. Both connectors support the same upper temperature limit.

Q: Are both connectors RoHS compliant?

A: Yes. Both the RJSNEJF8108 and RJSAE-5381-08 are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting equivalent environmental and regulatory requirements.

Q: What packaging is available for the RJSAE-5381-08?

A: The RJSAE-5381-08 is supplied in tray packaging. Verify packaging requirements for your procurement process.
