RJSNEJF89A8 Equivalent & Substitute Parts

Part Overview

The RJSNEJF89A8 is a modular jack connector manufactured by Amphenol ICC (Commercial Products) in the RJSNE series. This component is an 8-position 8-contact (8p8c) RJ45 Ethernet jack with 90° right-angle orientation, shielded design, and through-hole solder termination. The connector features board lock functionality, green LED indicator, and phosphor bronze contacts with gold finish.

The RJSNEJF89A8 is classified as obsolete. Locating equivalent substitute parts is necessary to support legacy system maintenance, design updates, and continued component availability for production environments where this connector is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJF89A8 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Orientation: 90° Angle (Right)
• Mounting Type: Through Hole
• Termination: Solder
• Shielding: Shielded
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic

Allowable Variations:

• Contact Finish Thickness: May vary (original 30.0µin; substitute may differ)
• Operating Temperature Range: Substitute may extend the lower limit (original -40°C; substitute may extend to -55°C)
• Shielding Enhancement: Substitute may include additional EMI Finger shielding
• Product Status: Substitute may be Active (original is Obsolete)
• Packaging: Substitute may differ (original unspecified; substitute in Tray)

The RJSAE538908 meets all mandatory matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538908 is a direct functional substitute for the RJSNEJF89A8 based on the following engineering criteria:

Compliance and Regulatory Status: Both parts are RoHS Compliant and classified under identical ECCN (EAR99) and HTSUS (8536.69.4040) codes, ensuring regulatory equivalence for procurement and export purposes.

Product Status Advantage: The RJSAE538908 carries Active product status, whereas the RJSNEJF89A8 is Obsolete. Selection of the RJSAE538908 provides access to current manufacturing, quality assurance processes, and long-term availability.

Enhanced Shielding: The RJSAE538908 incorporates EMI Finger shielding in addition to standard shielding, providing improved electromagnetic interference rejection compared to the original part.

Extended Temperature Range: The RJSAE538908 operates across -55°C to 85°C, extending the lower temperature limit by 15°C relative to the RJSNEJF89A8 (-40°C to 85°C). This expansion accommodates broader environmental operating conditions.

Increased Contact Durability: The RJSAE538908 features 50.0µin (1.27µm) gold contact finish thickness, compared to 30.0µin (0.76µm) on the original part, providing enhanced contact wear resistance and longevity.

Functional Equivalence: All critical electrical and mechanical parameters remain identical: 8p8c RJ45 configuration, 90° right-angle orientation, through-hole solder termination, board lock feature, green LED indicator, and phosphor bronze contact material.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538908 be used as a direct replacement for the RJSNEJF89A8 in existing designs?

A: Yes. The RJSAE538908 matches all mandatory electrical and mechanical parameters of the RJSNEJF89A8, including connector type, contact configuration, orientation, mounting method, and termination. The substitute is functionally equivalent for PCB layout and circuit integration.

Q: What is the significance of the EMI Finger shielding on the RJSAE538908?

A: The EMI Finger shielding provides additional electromagnetic interference rejection beyond standard shielding. This enhancement improves signal integrity in environments with elevated electromagnetic noise, though both parts meet the same shielded connector classification.

Q: Does the thicker gold finish on the RJSAE538908 affect compatibility?

A: No. The increased contact finish thickness (50.0µin versus 30.0µin) does not affect mechanical or electrical compatibility. The thicker finish enhances contact durability and wear resistance during mating cycles.

Q: Why does the RJSAE538908 have a wider operating temperature range?

A: The RJSAE538908 extends the lower operating limit to -55°C, compared to -40°C on the RJSNEJF89A8. This expanded range reflects the design and qualification of the RJSAE series and provides operational flexibility for cold environment applications.

Q: What is the packaging difference between these parts?

A: The RJSNEJF89A8 packaging is unspecified in available documentation. The RJSAE538908 is supplied in Tray packaging. Confirm packaging requirements with your procurement specification before ordering.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNEJF89A8 and RJSAE538908 are RoHS Compliant and carry identical ECCN and HTSUS classifications, ensuring regulatory equivalence.

Q: Why is the RJSNEJF89A8 marked as Obsolete?

A: Obsolete status indicates the part is no longer in active production. The RJSAE538908, with Active status, represents the current manufacturing equivalent and is recommended for new designs and legacy system updates.
