RJSNEJ38JA8

Part Overview

The RJSNEJ38JA8 is a jack modular connector designed for 8p8c (RJ45, Ethernet) applications with 90° right-angle orientation and shielded construction with EMI finger protection. This component is classified as obsolete, necessitating the identification of active equivalent alternatives to ensure continued design support and procurement availability. The part features through-hole solder termination, phosphor bronze contacts with gold finish, and operates across a temperature range of -40°C to 85°C.

Substitute Part Grouping Explanation

The RJSNEJ38JA8 can be substituted with RJSAE538EA8 based on the following critical electrical and mechanical parameters:

Core Compatibility Parameters:

• Connector Type: Jack (identical)
• Contact Configuration: 8p8c (RJ45, Ethernet) (identical)
• Ports and Rows: 8 ports, 2 rows (identical)
• Mounting Type: Through Hole (identical)
• Orientation: 90° Angle (Right) (identical)
• Termination Method: Solder (identical)
• Shielding Configuration: Shielded, EMI Finger (identical)
• Contact Material: Phosphor Bronze (identical)
• Contact Finish: Gold (identical)
• Housing Material: Thermoplastic (identical)
• Environmental Compliance: RoHS Compliant, MSL 1 (identical)

These parameters define the mechanical interface and functional equivalence between the two components. The RJSAE538EA8 maintains full compatibility with applications designed for the RJSNEJ38JA8.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538EA8 is the direct functional equivalent for the obsolete RJSNEJ38JA8. Both components are RoHS Compliant and carry MSL 1 rating, meeting environmental and reliability standards. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The RJSAE538EA8 offers design improvements relative to the original part: an extended operating temperature range at the lower limit (-55°C vs. -40°C) and increased contact finish thickness (50.0µin vs. 30.0µin), which enhances contact durability. These differences position the substitute as a direct replacement without design modifications required.

For applications where the RJSNEJ38JA8 was originally specified, the RJSAE538EA8 provides equivalent mechanical and electrical performance while eliminating obsolescence risk.

Frequently Asked Questions (FAQ)

Q: Can RJSAE538EA8 be used as a direct drop-in replacement for RJSNEJ38JA8?

A: Yes. Both connectors share identical specifications for connector type, contact configuration (8p8c RJ45), mounting type (through-hole), orientation (90° right-angle), termination method (solder), shielding design, contact material, and housing material. No PCB layout or circuit modifications are required.

Q: What are the differences between these two parts?

A: The RJSAE538EA8 provides an extended operating temperature range (-55°C to 85°C vs. -40°C to 85°C) and thicker gold contact finish (50.0µin vs. 30.0µin). These represent manufacturing improvements rather than functional changes.

Q: Why is the RJSNEJ38JA8 no longer available?

A: The RJSNEJ38JA8 is classified as obsolete. The RJSAE538EA8 is the active equivalent part that replaces it in the manufacturer's product portfolio.

Q: Are both parts RoHS compliant?

A: Yes. Both RJSNEJ38JA8 and RJSAE538EA8 are RoHS Compliant with MSL 1 (Unlimited) rating, meeting environmental and moisture sensitivity requirements.

Q: What is the connector interface standard?

A: Both parts are 8p8c (RJ45, Ethernet) modular connectors, conforming to standard Ethernet jack specifications for through-hole PCB mounting with right-angle orientation.
