The RJSAE538B08 satisfies all substitution criteria while offering enhanced shielding through EMI finger technology and improved contact durability with increased gold plating thickness.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538B08 is the direct active equivalent for the obsolete RJSNEJF8B08. Both connectors are RoHS compliant and maintain identical electrical and mechanical specifications for 8p8c (RJ45, Ethernet) jack applications with 90° right-angle through-hole solder termination.

Selection Basis:

The RJSAE538B08 provides functional equivalence with the following enhancements:

• Product Status: Active manufacturing status ensures long-term availability and supply chain continuity, eliminating obsolescence risk associated with the RJSNEJF8B08.
• Enhanced Shielding: EMI finger technology provides improved electromagnetic interference rejection compared to standard shielding.
• Increased Contact Durability: Gold plating thickness of 50.0µin (1.27µm) versus 30.0µin (0.76µm) extends contact life and improves wear resistance.
• Extended Operating Temperature: Operating range of -55°C to 85°C provides broader environmental compatibility compared to -40°C to 85°C.

Both parts maintain identical compliance certifications (RoHS, MSL 1) and are suitable for direct substitution in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538B08 be used as a direct replacement for the RJSNEJF8B08 in existing designs?

A: Yes. The RJSAE538B08 maintains electrical and mechanical equivalence across all critical parameters: 8p8c (RJ45, Ethernet) jack configuration, 90° right-angle orientation, through-hole solder termination, shielding, board lock functionality, and identical contact materials and finishes. No circuit or layout modifications are required.

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

A: The RJSNEJF8B08 features standard shielding. The RJSAE538B08 includes EMI finger technology in addition to shielding, providing enhanced electromagnetic interference rejection. Both are classified as shielded connectors and are electrically compatible.

Q: Why is the contact finish thickness different between the two parts?

A: The RJSAE538B08 specifies 50.0µin (1.27µm) gold plating compared to 30.0µin (0.76µm) on the RJSNEJF8B08. This increased thickness improves contact durability and wear resistance, particularly in high-cycle mating applications. Both finishes meet RoHS compliance requirements.

Q: Does the extended operating temperature range of the RJSAE538B08 affect compatibility?

A: No. The RJSAE538B08 operating range of -55°C to 85°C encompasses the RJSNEJF8B08 range of -40°C to 85°C. The extended lower temperature limit provides additional environmental flexibility without affecting compatibility in applications within the original temperature specification.

Q: Are both connectors available in the same packaging?

A: The RJSNEJF8B08 packaging is not specified in the provided data. The RJSAE538B08 is supplied in Tray packaging. Verify packaging requirements for your specific procurement and assembly processes.

Q: What is the inventory status for these parts?

A: The RJSNEJF8B08 is obsolete with 725 pieces in stock. The RJSAE538B08 is active with 863 pieces in stock, providing reliable long-term availability for new designs and field replacements.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNEJF8B08 and RJSAE538B08 are RoHS compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and regulatory requirements for commercial and industrial applications.
