Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the RJSNEJF8HA8 is based on the following critical electrical and mechanical parameters:

• Connector Type & Configuration: Jack, 8p8c (RJ45, Ethernet) — both main and substitute must maintain identical pinout and contact arrangement
• Mechanical Orientation & Form Factor: 90° right-angle, through-hole mounting with solder termination — ensures direct board-level compatibility
• Contact Material & Electrical Properties: Phosphor Bronze with gold finish — maintains signal integrity and corrosion resistance
• Shielding: Shielded design required for electromagnetic compatibility
• Operating Temperature: -40°C to +85°C operating range
• Compliance & Environmental: RoHS compliant, MSL 1 rating

The RJSAE538H08 qualifies as a direct substitute because it shares all mandatory electrical and mechanical parameters while offering enhanced EMI performance through integrated EMI finger shielding and an expanded operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538H08 is the direct equivalent to the obsolete RJSNEJF8HA8. Both connectors meet identical electrical and mechanical specifications and share full RoHS compliance. The RJSAE538H08 offers the following advantages:

• Active Product Status: The RJSAE538H08 maintains active production status, ensuring long-term availability and supply chain continuity
• Enhanced EMI Shielding: Integration of EMI finger shielding provides superior electromagnetic interference rejection in high-noise environments
• Expanded Temperature Range: Operating range of -55°C to +85°C extends applicability to more stringent thermal environments
• Improved Contact Finish: Gold plating thickness of 50.0µin (1.27µm) provides greater durability compared to the original 30.0µin (0.76µm)

Both components are RoHS compliant with MSL 1 ratings and require identical through-hole solder termination and PCB layout considerations.

Frequently Asked Questions (FAQ)

Q: Can RJSAE538H08 directly replace RJSNEJF8HA8 in existing designs? A: Yes. Both connectors share identical mechanical and electrical parameters: 8p8c (RJ45, Ethernet) configuration, 90° right-angle orientation, through-hole solder termination, and shielded design. No design modifications are required for the substitute.

Q: What are the differences between these connectors? A: The RJSAE538H08 includes EMI finger shielding for enhanced electromagnetic compatibility, features a thicker gold contact finish (50.0µin vs. 30.0µin), and supports an expanded operating temperature range (-55°C to +85°C vs. -40°C to +85°C). The RJSNEJF8HA8 is obsolete; the RJSAE538H08 is active production.

Q: Are there any compatibility concerns with solder termination? A: No. Both connectors utilize identical through-hole solder termination methods. PCB mounting holes and pad layouts remain compatible without modification.

Q: Does the thicker gold plating affect performance? A: The increased contact finish thickness (50.0µin on the substitute vs. 30.0µin on the original) provides extended contact durability and corrosion resistance. This represents an enhancement with no negative impact on electrical performance.

Q: What is the significance of the EMI finger shielding on the substitute? A: The RJSAE538H08 incorporates EMI finger shielding for superior electromagnetic interference mitigation. This feature is optional for backward compatibility but recommended for applications operating in electromagnetically demanding environments.

Q: Are both parts RoHS compliant? A: Yes. Both RJSNEJF8HA8 and RJSAE538H08 are RoHS compliant with MSL 1 ratings, confirming compatibility with modern manufacturing standards and unlimited moisture exposure.
