RJSNE5089A8

Part Overview

The RJSNE5089A8 is a modular jack connector (RJ45/Ethernet) manufactured by Amphenol ICC (Commercial Products). This 8p8c unshielded connector features a 90° right-angle through-hole mount with solder termination and integrated green LED indicator. The product is currently listed as obsolete, making alternative solutions necessary for ongoing procurement and system integration. Substitute parts must maintain electrical and mechanical compatibility across key parameters including connector type, contact configuration, mounting orientation, termination method, and environmental ratings.

Key Parameters

Substitute Part Grouping Explanation

The RJSAE5089A8 qualifies as a direct substitute for the RJSNE5089A8 based on the following critical parameters that must remain constant across substitute parts:

Electrical Parameters (Must Match):

• Connector Type: Jack modular connector (8p8c RJ45 Ethernet)
• Contact Material: Phosphor Bronze
• Contact Finish: Gold (50.0µin / 1.27µm thickness)
• Shielding: Unshielded

Mechanical Parameters (Must Match):

• Number of Positions/Contacts: 8p8c
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Tab Direction: Up and Down
• Housing Material: Thermoplastic

Environmental Compatibility:

• Operating Temperature Range: -40°C to 70°C (substitute) vs. -40°C to 85°C (original)
• RoHS Compliance: Both compliant

The substitute part maintains all critical electrical and mechanical characteristics required for direct PCB integration while offering active product status and improved procurement availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: RJSAE5089A8

The RJSAE5089A8 serves as the direct substitute for the obsolete RJSNE5089A8. Both parts share identical electrical and mechanical specifications across all critical parameters: 8p8c RJ45 jack configuration, through-hole solder termination, 90° right-angle orientation, phosphor bronze contacts with gold finish (50.0µin), and thermoplastic unshielded housing.

The substitute part offers the following advantages:

• Active product status with ongoing manufacturer support
• Superior inventory availability (972 units in stock)
• RoHS compliant certification maintained
• Same contact finish and material specifications

Operating Temperature Consideration:

The RJSAE5089A8 supports an operating temperature range of -40°C to 70°C, compared to the original part's -40°C to 85°C range. This represents a 15°C reduction in upper temperature limit. Design validation is required if applications operate continuously above 70°C ambient conditions. For standard ethernet and networking applications operating within typical environmental ranges (typically -20°C to 60°C), this specification change does not impact system performance or reliability.

Frequently Asked Questions (FAQ)

Q: Can RJSAE5089A8 directly replace RJSNE5089A8 on existing PCB designs?

A: Yes. Both connectors maintain identical through-hole mounting footprints, solder pad configurations, 90° right-angle orientation, and lead spacing. No PCB layout modifications are required for direct substitution.

Q: What is the difference in operating temperature ranges between these parts?

A: The original RJSNE5089A8 operates from -40°C to 85°C, while the substitute RJSAE5089A8 operates from -40°C to 70°C. The 15°C difference in maximum temperature applies only to continuous operation at elevated ambient conditions. Standard networking and ethernet applications typically operate within -20°C to 60°C ranges and are unaffected by this specification change.

Q: Are the contact materials and finishes identical?

A: Yes. Both parts use phosphor bronze contacts with 50.0 microinches (1.27µm) gold plating, ensuring equivalent electrical conductivity, contact resistance, and corrosion resistance characteristics.

Q: What is the LED indicator status on both parts?

A: Both the RJSNE5089A8 and RJSAE5089A8 include integrated green LED indicators for link status indication in ethernet applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the original and substitute parts carry full RoHS compliance certification, meeting all regulatory requirements for lead-free materials and hazardous substance restrictions.

Q: Why is the original part listed as obsolete?

A: Product obsolescence reflects Amphenol ICC's manufacturing and distribution lifecycle decisions. The RJSAE5089A8 (Active status) represents the current production equivalent, providing continued access to functionally identical connector technology with superior availability.
