• Termination: Solder
• Shielding: Shielded, EMI Finger
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• RoHS Compliance: Yes
• MSL Rating: 1 (Unlimited)

The RJSAE538EA8 satisfies all mandatory parameters and is classified as an active product, making it a direct functional equivalent for the obsolete RJSNEJ38E08.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538EA8 is the direct equivalent substitute for the obsolete RJSNEJ38E08. Both parts are manufactured by Amphenol ICC (Commercial Products) and share identical functional specifications across all critical parameters: 8p8c RJ45 jack configuration, 90° right-angle orientation, through-hole solder termination, shielded design with EMI finger, phosphor bronze contacts with gold finish, and thermoplastic housing.

The RJSAE538EA8 offers two performance enhancements over the main part:

1. Contact Finish Thickness: The substitute provides 50.0µin (1.27µm) gold plating compared to 30.0µin (0.76µm) on the main part, delivering improved contact durability and corrosion resistance.

2. Operating Temperature Range: The substitute operates across -55°C to 85°C, extending the lower temperature limit by 15°C compared to the main part's -40°C to 85°C range.

Both parts maintain RoHS compliance and MSL 1 (Unlimited) moisture sensitivity rating. The RJSAE538EA8 is currently in active production status, ensuring long-term supply availability and design continuity for new applications and field replacements.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538EA8 be used as a direct replacement for the RJSNEJ38E08 in existing designs?

A: Yes. The RJSAE538EA8 is functionally equivalent across all critical parameters: connector type, contact count, mounting method, orientation, termination, shielding, contact materials, and finish. Both parts are RoHS compliant with identical MSL ratings. No design modifications are required.

Q: What is the difference in contact finish thickness between these parts?

A: The RJSNEJ38E08 specifies 30.0µin (0.76µm) gold plating, while the RJSAE538EA8 provides 50.0µin (1.27µm). The thicker plating on the substitute enhances contact durability and extends service life in high-cycle mating applications.

Q: Does the RJSAE538EA8 support the same operating temperature range?

A: The RJSAE538EA8 supports -55°C to 85°C, which encompasses the RJSNEJ38E08 range of -40°C to 85°C. The substitute is suitable for applications requiring extended low-temperature operation.

Q: Are both parts suitable for through-hole PCB assembly?

A: Yes. Both the RJSNEJ38E08 and RJSAE538EA8 are designed for through-hole solder termination on printed circuit boards. They share identical mounting specifications and footprint requirements.

Q: What is the significance of the "Board Lock" feature on the main part?

A: The RJSNEJ38E08 includes a board lock feature. This parameter is not specified for the RJSAE538EA8 in the provided data. Verify mechanical compatibility with your PCB design if board lock functionality is critical to your application.

Q: Are both parts shielded for EMI protection?

A: Yes. Both the RJSNEJ38E08 and RJSAE538EA8 feature shielding with EMI finger protection, suitable for Ethernet and other noise-sensitive applications requiring electromagnetic interference mitigation.

Q: What is the current availability status of these parts?

A: The RJSNEJ38E08 is obsolete. The RJSAE538EA8 is in active production with 1107 pieces in current inventory, ensuring reliable supply for new designs and field service requirements.
