Key Parameters

Substitute Part Grouping Explanation

The RJSAE508B08 qualifies as a direct substitute for the RJSNEG08B08 based on the following critical alignment of electrical and mechanical parameters:

Matching Parameters:

• Connector type: Jack
• Contact positions: 8p8c (RJ45, Ethernet)
• Orientation: 90° right-angle
• Mounting: Through hole solder termination
• Shielding: Unshielded
• Housing material: Thermoplastic
• Features: Board lock with dual-color LED (Red, Green)
• Tab direction: Up and down
• Contact material: Phosphor bronze with gold finish
• RoHS compliance: Both parts RoHS compliant
• Moisture sensitivity level: MSL 1 (Unlimited)

The substitute part maintains functional and physical compatibility while offering improved specifications in contact finish thickness and extended low-temperature operating range.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE508B08 is the recommended substitute for the obsolete RJSNEG08B08. Both parts maintain full RoHS compliance and MSL 1 rating, ensuring regulatory and environmental compatibility. The substitute part offers extended low-temperature operability (-55°C versus -40°C) and enhanced contact finish thickness (50.0µin versus 15.0µin), providing improved durability and contact reliability. As an active product with current manufacturer support, the RJSAE508B08 ensures long-term design viability and procurement availability.

Frequently Asked Questions (FAQ)

Q: Can RJSAE508B08 directly replace RJSNEG08B08 in existing designs? A: Yes. Both parts share identical connector type, contact configuration, orientation, mounting method, and shielding characteristics. The substitute part maintains full mechanical and electrical compatibility.

Q: What is the significance of the contact finish thickness difference? A: The RJSAE508B08 provides 50.0µin (1.27µm) gold plating compared to 15.0µin (0.38µm) on the original part. The increased thickness extends contact life and corrosion resistance in extended-use applications.

Q: Why is operating temperature range extended on the substitute? A: The RJSAE508B08 operates from -55°C to 85°C compared to -40°C to 85°C for the RJSNEG08B08. The extended low-temperature range accommodates broader environmental conditions without performance degradation.

Q: Are packaging considerations relevant to substitution? A: The original part uses standard packaging while the substitute ships in trays. Packaging difference does not affect functional compatibility or design integration.

Q: Do both parts maintain equivalent RoHS and moisture sensitivity compliance? A: Yes. Both parts are RoHS compliant with MSL 1 (Unlimited) rating, ensuring regulatory conformance and immunity from moisture sensitivity constraints during storage and handling.
