Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete RJSNE5F8DA8 is based on strict electrical and mechanical parameter alignment. The substitute part RJSAE538H08 maintains compatibility through the following critical parameters:

Electrical Compatibility:

• Identical connector type (Jack)
• Identical contact configuration (8p8c RJ45, Ethernet)
• Identical port and row count (8 ports, 2 rows)
• Identical contact material (Phosphor Bronze)
• Identical contact finish and thickness (Gold, 50.0µin)
• Identical shielding classification (Shielded)

Mechanical Compatibility:

• Identical mounting type (Through Hole)
• Identical orientation (90° Angle Right)
• Identical termination method (Solder)
• Identical housing material (Thermoplastic)
• Identical tab direction (Up and Down)

Regulatory Compliance:

• Identical RoHS compliance status
• Identical MSL rating (1 - Unlimited)
• Identical ECCN and HTSUS classifications

The substitute part operates within an extended temperature range (-55°C ~ 85°C versus -40°C ~ 85°C) and includes EMI finger shielding enhancement, representing a functional upgrade while maintaining full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538H08 is the direct substitute for the obsolete RJSNE5F8DA8. Selection is based on the following engineering criteria:

Regulatory and Compliance Alignment: Both parts maintain identical RoHS compliance status and MSL ratings, ensuring regulatory requirements are met in replacement scenarios. ECCN and HTSUS classifications are identical, supporting supply chain continuity.

Product Status Consideration: The RJSNE5F8DA8 is classified as obsolete, while the RJSAE538H08 maintains active product status. This distinction is critical for long-term availability, supply chain reliability, and manufacturer support. Active status ensures continued manufacturing, quality assurance, and technical documentation availability.

Electrical and Mechanical Equivalence: All critical electrical parameters—contact configuration, material composition, finish specifications, and shielding—are identical between the two parts. Mechanical parameters including mounting type, orientation, termination method, and housing material are fully compatible, enabling direct substitution without circuit board redesign or assembly process modification.

Enhanced Performance Characteristics: The RJSAE538H08 provides an extended operating temperature range (-55°C to 85°C versus -40°C to 85°C) and includes EMI finger shielding enhancement. These characteristics represent functional improvements that do not compromise backward compatibility and provide additional margin for demanding thermal or electromagnetic environments.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538H08 be used as a direct replacement for the RJSNE5F8DA8 without circuit board modifications?

A: Yes. The RJSAE538H08 maintains identical mechanical and electrical parameters including mounting type (through hole), orientation (90° right angle), termination method (solder), and contact configuration (8p8c RJ45). No circuit board layout changes are required.

Q: What is the significance of the EMI finger shielding in the RJSAE538H08?

A: The EMI finger shielding provides enhanced electromagnetic interference rejection. This is an additional feature that does not affect compatibility with the original RJSNE5F8DA8 specification and represents a performance enhancement for applications requiring improved EMI performance.

Q: Are the contact materials and finishes identical between these two parts?

A: Yes. Both parts use phosphor bronze contacts with gold finish at 50.0µin (1.27µm) thickness, ensuring identical electrical performance and contact reliability.

Q: Why is the RJSNE5F8DA8 listed as obsolete?

A: Product obsolescence is determined by the manufacturer based on production lifecycle decisions. The RJSAE538H08 represents the active equivalent, ensuring continued availability and manufacturer support for new designs and replacement applications.

Q: Does the extended temperature range of the RJSAE538H08 affect compatibility?

A: No. The extended operating temperature range (-55°C to 85°C) is a superset of the original specification (-40°C to 85°C). This provides additional thermal margin and does not compromise compatibility with applications designed for the original temperature range.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNE5F8DA8 and RJSAE538H08 are RoHS compliant with identical MSL ratings (1 - Unlimited), supporting regulatory requirements in all applicable markets.

Q: What is the inventory status for the substitute part?

A: The RJSAE538H08 has 960 pieces in stock as new original inventory, providing immediate availability for replacement and new design applications.
