Key Parameters

Substitute Part Grouping Explanation

Substitution suitability for the RJSNEJ08108 is determined by strict alignment across the following critical parameters:

• Connector Type & Configuration: Must be a Jack connector with 8p8c (RJ45) contacts
• Mechanical Compatibility: 90° right-angle orientation with through-hole mounting and solder termination
• Electrical Properties: Unshielded design with phosphor bronze contacts and gold plating
• Environmental Ratings: Operating temperature capability and RoHS compliance status
• Form Factor: Housing material and physical tab direction

The RJSAE508108 meets these substitution criteria as an active equivalent, sharing identical connector type, pin configuration, orientation, mounting method, termination type, and shielding characteristics. Both parts utilize the same contact materials and finish specifications, ensuring electrical and mechanical compatibility within circuit board assemblies.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE508108 is an active equivalent for the obsolete RJSNEJ08108. Both parts are RoHS compliant and share identical environmental certifications (MSL 1). The substitute provides an extended operating temperature range (-55°C to 85°C versus -40°C to 85°C), enhancing thermal performance for demanding applications. The RJSAE508108 includes a board lock feature, offering mechanical retention benefits not present in the original part. Gold contact finish thickness is increased (50.0µin versus 30.0µin), providing enhanced contact durability and extended service life.

Frequently Asked Questions (FAQ)

Q: Are RJSNEJ08108 and RJSAE508108 pin-for-pin compatible? A: Yes. Both connectors utilize identical 8p8c (RJ45) contact configurations with phosphor bronze contacts and gold plating. Through-hole solder termination and mechanical orientation are identical, ensuring direct substitution in existing circuit board layouts.

Q: What is the difference in operating temperature capability? A: RJSNEJ08108 operates from -40°C to 85°C, while RJSAE508108 extends the minimum operating temperature to -55°C. This enhanced capability does not impact applications within the original temperature range.

Q: Does the increased contact finish thickness affect performance? A: The RJSAE508108 contact finish thickness of 50.0µin (1.27µm) versus 30.0µin (0.76µm) improves contact durability and resistance to mating cycle wear. This enhancement maintains electrical performance specifications within standard RJ45 operating parameters.

Q: What is the board lock feature in RJSAE508108? A: The board lock feature provides mechanical retention of the connector to the circuit board, preventing accidental disconnection. This is an additional benefit not present in the original RJSNEJ08108 design.

Q: Are both parts RoHS compliant? A: Yes. Both RJSNEJ08108 and RJSAE508108 are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting equivalent environmental and regulatory requirements.

Q: What packaging is available for the substitute part? A: RJSAE508108 is supplied in Tray packaging, suitable for automated assembly processes and high-volume manufacturing operations.
