Substitute Part Grouping Explanation

Substitution of the RJSNEJF8P08 with the RJSAE538B08 is based on alignment of the following critical electrical and mechanical parameters:

• Connector Type & Contact Configuration: Both parts are Jack-type modular connectors with 8p8c (RJ45, Ethernet) contact configuration, ensuring pin-to-pin compatibility.
• Mounting & Orientation: Both feature through-hole solder termination with 90° right-angle (right) orientation, enabling direct PCB layout substitution.
• Shielding Architecture: Both connectors provide shielded designs for electromagnetic interference mitigation.
• Contact Properties: Both utilize phosphor bronze contacts with gold finish, maintaining electrical performance and reliability.
• Housing Material: Thermoplastic housing in both parts ensures consistent mechanical durability and thermal performance.
• Regulatory Compliance: Both parts are RoHS compliant with MSL 1 rating, meeting current electronic components standards.
• Functional Features: Both connectors include board lock and dual-color LED indicators (Red and Green).

The RJSAE538B08 additionally incorporates an EMI finger feature and is classified as active product status, representing a direct technical upgrade path from the obsolete RJSNEJF8P08.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538B08 is the appropriate substitute for the obsolete RJSNEJF8P08 based on the following factors:

Product Status: The RJSNEJF8P08 is classified as obsolete, limiting availability for future procurement. The RJSAE538B08 is active and fully supported by Amphenol ICC, ensuring long-term supply chain viability and manufacturing continuity.

Regulatory Compliance: Both connectors maintain RoHS compliance and EAR99 classification, satisfying current export and manufacturing regulations without redesign requirements.

Electrical Compatibility: All critical electrical parameters—connector type, pin configuration, contact material, finish composition, and shielding architecture—are equivalent between the two parts, enabling direct functional substitution.

Enhanced Features: The RJSAE538B08 incorporates an EMI finger and offers increased contact finish thickness (50.0µin versus 30.0µin), providing enhanced electromagnetic shielding and improved contact durability for extended operational life.

Operating Temperature Range: The RJSAE538B08 supports an extended lower temperature limit (-55°C versus -40°C), broadening applicability across wider thermal environments while maintaining the same upper temperature ceiling.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538B08 directly replace the RJSNEJF8P08 on existing PCB assemblies?

A: Yes. Both connectors share identical mounting characteristics (through-hole, 90° right orientation), pinout configuration (8p8c RJ45), and solder termination methodology, enabling direct PCB footprint compatibility without redesign.

Q: What is the functional difference between the EMI finger in the RJSAE538B08 and the base shielding in the RJSNEJF8P08?

A: The EMI finger provides additional electromagnetic interference suppression through direct grounding contact with the PCB plane, enhancing signal integrity in noise-sensitive applications. Both parts provide electromagnetic shielding; the RJSAE538B08 offers additional EMI mitigation.

Q: Does the difference in contact finish thickness affect electrical performance?

A: Contact finish thickness (30.0µin versus 50.0µin) does not alter baseline electrical performance. The increased thickness in the RJSAE538B08 enhances contact wear resistance and operational longevity in high-cycle insertion/withdrawal environments.

Q: Are both connectors suitable for the same temperature ranges in industrial applications?

A: The RJSNEJF8P08 operates from -40°C to 85°C, while the RJSAE538B08 operates from -55°C to 85°C. For applications requiring operation below -40°C, the RJSAE538B08 is the appropriate selection.

Q: What is the packaging difference between these two parts?

A: The RJSNEJF8P08 is provided in standard packaging (unspecified in documentation), while the RJSAE538B08 is supplied in tray packaging, facilitating automated assembly and inventory management.

Q: Are both parts certified for the same regulatory standards?

A: Yes. Both connectors are RoHS compliant, classified under ECCN EAR99, and assigned HTSUS code 8536.69.4040, satisfying identical regulatory requirements for export and manufacturing compliance.

Q: Why is the RJSNEJF8P08 marked as obsolete?

A: Product obsolescence reflects manufacturer discontinuation and end-of-life status. The RJSAE538B08 serves as the active successor, offering equivalent functionality with enhanced features and long-term availability assurance.
