RJSNEJ38AA8

Part Overview

The RJSNEJ38AA8 is a Jack Modular Connector (RJ45/Ethernet) manufactured by Amphenol ICC (Commercial Products). This through-hole, right-angle shielded connector features 8 positions/contacts with solder termination and board lock capability. The part is currently marked as Obsolete, making the identification of suitable substitute components essential for ongoing design support and procurement continuity. Alternative parts must maintain compatibility with the 8p8c (RJ45) standard while meeting identical electrical and mechanical interface requirements.

Key Parameters

Substitute Part Grouping Explanation

The RJSNEJ38AA8 can be substituted with the RJSAEJ38AC8 based on the following critical parameters that define interchangeability:

• Connector Type & Contact Configuration: Both are Jack connectors with 8p8c (RJ45/Ethernet) contact positions
• Mechanical Interface: Identical through-hole mounting with 90° right-angle orientation
• Electrical Properties: Matching phosphor bronze contacts with gold finish (30.0µin thickness)
• EMI/Shielding: Both feature shielded construction with EMI fingers
• Environmental Compliance: Both are RoHS Compliant with MSL 1 (Unlimited)
• Termination Method: Both use solder termination

The substitution is valid where the main part's obsolescence status necessitates a functional equivalent from an active product line.

Parameter Comparison

Engineering Selection Recommendations

The RJSAEJ38AC8 is a direct functional equivalent to the RJSNEJ38AA8. The substitute part is sourced from the same manufacturer (Amphenol ICC) and maintains all critical electrical and mechanical specifications necessary for 8p8c (RJ45/Ethernet) jack applications. Notably, the RJSAEJ38AC8 carries an Active product status, ensuring ongoing availability and supply chain continuity, whereas the original part is classified as Obsolete.

Both parts are RoHS Compliant and carry identical Moisture Sensitivity Levels, meeting current environmental and regulatory standards. The RJSAEJ38AC8 exhibits a wider operating temperature range (-55°C to 85°C compared to -40°C to 85°C), providing enhanced thermal performance in demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the RJSAEJ38AC8 directly replace the RJSNEJ38AA8 in existing designs? A: Yes. Both connectors are jack-type, 8p8c (RJ45) configurations with through-hole solder termination and identical mechanical mounting (90° right-angle). The electrical interface, contact materials, finishes, and shielding specifications are fully compatible.

Q: What is the primary difference between these two parts? A: The RJSNEJ38AA8 is obsolete, while the RJSAEJ38AC8 is active. Additionally, the substitute part supports a wider operating temperature range (-55°C to 85°C versus -40°C to 85°C), offering greater thermal margin for demanding environments.

Q: Are there packaging differences between these parts? A: The RJSNEJ38AA8 packaging is not specified in the reference data. The RJSAEJ38AC8 is supplied in Tray packaging. Both parts are RoHS Compliant with MSL 1 (Unlimited) rating.

Q: What is the basis for substitution validity? A: Substitution is valid based on identical contact configuration (8p8c RJ45), mounting type (through-hole), orientation (90° right-angle), termination method (solder), shielding (EMI finger), contact material (phosphor bronze with gold finish), and regulatory compliance (RoHS). These parameters ensure electrical and mechanical compatibility in 8p8c jack applications.

Q: Are there inventory considerations? A: Current inventory shows 994 pieces of the RJSAEJ38AC8 available as new original stock, compared to 871 pieces for the obsolete RJSNEJ38AA8. The active product status of the substitute ensures sustained availability for future production.
