RJSNE538JA8 Equivalent & Substitute Parts

Part Overview

The RJSNE538JA8 is a shielded modular jack connector manufactured by Amphenol ICC (Commercial Products) in the RJSNE series. This 8p8c (RJ45, Ethernet) connector features a 90° right-angle orientation with through-hole solder termination and integrated EMI shielding with an EMI finger. The connector includes board lock features and dual-color LED indicators (Red, Green-Yellow).

The RJSNE538JA8 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this connector specification is required.

Substitute Part Grouping Explanation

Substitution of the RJSNE538JA8 is based on electrical and mechanical parameter equivalence. The following parameters must remain constant for a part to function as a direct substitute:

Connector Type: Jack configuration
Contact Configuration: 8p8c (RJ45, Ethernet) standard
Mounting Method: Through-hole solder termination
Physical Orientation: 90° right-angle mounting
Shielding Architecture: Shielded design with EMI finger
Contact Materials and Finish: Phosphor bronze with gold plating at 50.0µin thickness
Housing Material: Thermoplastic construction
LED Indicators: Dual-color LED support (Red, Green-Yellow)
Tab Configuration: Up and down tab direction
Environmental Compliance: RoHS compliance requirement

The RJSAE538JA8 meets all these criteria and is identified as a direct substitute for the obsolete RJSNE538JA8.

Engineering Selection Recommendations

The RJSAE538JA8 is the direct substitute for the obsolete RJSNE538JA8. Both parts are manufactured by Amphenol ICC (Commercial Products) and share identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The RJSNE538JA8 is obsolete, while the RJSAE538JA8 is active. Selection of the active substitute part ensures ongoing component availability and supply chain continuity.

Compliance Status: Both parts maintain RoHS compliance, satisfying regulatory requirements for new designs and production environments.

Operating Temperature Differential: The RJSNE538JA8 operates across -40°C to 85°C, while the RJSAE538JA8 operates across -40°C to 70°C. Applications requiring operation above 70°C must evaluate this temperature range limitation against specific system requirements.

Moisture Sensitivity: The RJSNE538JA8 carries MSL 1 (Unlimited), while the RJSAE538JA8 is listed as Not Applicable. This distinction does not affect substitution compatibility but reflects different handling and storage classifications.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538JA8 directly replace the RJSNE538JA8 in existing designs?

A: Yes. The RJSAE538JA8 is electrically and mechanically equivalent to the RJSNE538JA8 across all critical parameters including connector type, contact configuration, mounting method, orientation, shielding, contact materials, and finish specifications. Direct substitution is supported.

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

A: The RJSNE538JA8 is obsolete, while the RJSAE538JA8 is active. The RJSAE538JA8 also operates at a maximum temperature of 70°C compared to 85°C for the RJSNE538JA8. Applications operating above 70°C require evaluation of this specification.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNE538JA8 and RJSAE538JA8 are RoHS compliant, meeting environmental and regulatory requirements for commercial and industrial applications.

Q: Do both connectors support LED indicators?

A: Yes. Both parts feature dual-color LED indicators (Red, Green-Yellow) for status indication in network applications.

Q: What is the contact finish specification for both parts?

A: Both parts use gold-plated phosphor bronze contacts with a finish thickness of 50.0µin (1.27µm), ensuring consistent electrical performance and corrosion resistance.

Q: Are there packaging differences between these parts?

A: The RJSNE538JA8 packaging is not specified in the provided data. The RJSAE538JA8 is packaged in boxes. Verify packaging requirements for your specific procurement and handling procedures.

Q: Can these connectors be used in shielded applications?

A: Yes. Both connectors feature shielded design with EMI finger technology, suitable for applications requiring electromagnetic interference mitigation in network and communication systems.
