Key Parameters

Substitute Part Grouping Explanation

Substitution between the RJSNEJ38808 (Obsolete) and the RJSAEJ38808 (Active) is valid based on the following critical parameters that determine functional and mechanical interchangeability:

• Connector Type & Pin Configuration: Both are 8p8c (RJ45 Ethernet) jack connectors with identical pin layout and contact count (8 positions, 8 contacts)
• Mounting Type: Both feature through-hole solder termination, ensuring equivalent PCB integration
• Mechanical Orientation: Both specify 90° right-angle mounting orientation
• Shielding Configuration: Both incorporate shielded design with EMI finger protection
• Contact Material & Finish: Both utilize Phosphor Bronze contacts with Gold finish (30.0µin thickness) for identical electrical performance and corrosion resistance
• Housing Material: Both use Thermoplastic for mechanical and thermal stability
• Compliance: Both are RoHS Compliant with MSL 1 rating
• Electrical Ratings & Features: Both share identical pin-to-pin contact geometry and termination method

The RJSAEJ38808 is an active, modern equivalent manufactured by the same supplier with enhanced temperature range capability, making it a direct functional and mechanical replacement.

Parameter Comparison

Engineering Selection Recommendations

RJSNEJ38808 (Obsolete): This connector is suitable only for field service and replacement of existing installations where identical part matching is required. Long-term procurement is not recommended due to its Obsolete status.

RJSAEJ38808 (Active Substitute): This is the recommended selection for all new designs and forward-compatibility requirements. The RJSAEJ38808 is functionally and mechanically identical to the RJSNEJ38808, with superior availability and the same RoHS compliance certification. The extended operating temperature range (-55°C to 85°C versus -40°C to 85°C) provides additional thermal margin for demanding applications. Both parts carry RoHS Compliant status and unlimited MSL rating, satisfying environmental and reliability requirements.

Frequently Asked Questions (FAQ)

Q: Can the RJSAEJ38808 be used as a direct replacement for the RJSNEJ38808 in existing PCB designs? A: Yes. The RJSAEJ38808 is a direct pin-for-pin and mechanical replacement. Both connectors have identical through-hole footprints, 8p8c RJ45 pin configurations, and solder termination specifications. No PCB redesign is required.

Q: What is the key difference between these two parts? A: The primary difference is product status. The RJSNEJ38808 is Obsolete, while the RJSAEJ38808 is Active. The RJSAEJ38808 also provides a wider operating temperature range (-55°C to 85°C). All other critical parameters including pin count, contact material, finish, shielding, and compliance certifications are identical.

Q: Are there any shielding or EMI performance differences between the two connectors? A: No. Both the RJSNEJ38808 and RJSAEJ38808 feature identical shielded designs with EMI finger protection, identical contact materials (Phosphor Bronze), and identical gold plating thickness (30.0µin). EMI performance and signal integrity characteristics are equivalent.

Q: What certifications do both connectors hold? A: Both parts are RoHS Compliant with MSL 1 (Unlimited) rating. Both carry the same ECCN (EAR99) and HTSUS (8536.69.4040) classifications, simplifying compliance documentation and international shipping.

Q: Is the RJSAEJ38808 more expensive than the RJSNEJ38808? A: Cost comparison is outside the scope of this technical specification. Contact your authorized distributor for current pricing and availability. The RJSAEJ38808 is recommended based on its Active status and broader operational temperature range.

Q: Can I use either connector in a -55°C operating environment? A: The RJSNEJ38808 is rated to -40°C minimum. The RJSAEJ38808 extends to -55°C. For applications requiring -55°C operation, the RJSAEJ38808 is the qualified selection.
