Amphenol ICC RJSNEJF8908 Equivalent & Substitute Parts

Part Overview

The RJSNEJF8908 is a Jack Modular Connector 8p8c (RJ45, Ethernet) featuring 90° right-angle orientation with shielding. This connector is part of the RJSNE series from Amphenol ICC Commercial Products and is currently marked as obsolete product status. Due to its obsolescence, identification of equivalent substitute components with active product status is necessary to ensure continued availability and procurement reliability for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution between RJSNEJF8908 and RJSAE538908 is established based on the following critical parameters:

Core Functional Parameters:

• Connector Type: Both are Jack connectors
• Contact Configuration: Both are 8p8c (RJ45, Ethernet)
• Mounting Type: Both are Through Hole
• Orientation: Both feature 90° right-angle (Right) orientation
• Termination Method: Both use Solder termination
• Shielding: Both are shielded (RJSAE538908 includes additional EMI Finger feature)
• Contact Material: Both use Phosphor Bronze
• Contact Finish: Both have Gold plating
• Housing Material: Both use Thermoplastic
• RoHS Compliance: Both are RoHS Compliant
• MSL Rating: Both are rated MSL 1 (Unlimited)

Permissible Parameter Variations:

• Contact Finish Thickness: RJSNEJF8908 = 30.0µin (0.76µm); RJSAE538908 = 50.0µin (1.27µm) — increased thickness is functionally acceptable
• Operating Temperature Range: RJSNEJF8908 = -40°C ~ 85°C; RJSAE538908 = -55°C ~ 85°C — expanded lower temperature rating is functionally compatible
• EMI Shielding Feature: RJSAE538908 includes EMI Finger enhancement not present in RJSNEJF8908 — additional feature does not prevent substitution
• Product Status: RJSNEJF8908 = Obsolete; RJSAE538908 = Active — active status enables continued supply

Parameter Comparison

Engineering Selection Recommendations

For RJSNEJF8908 Replacement: The RJSAE538908 is the specified substitute component. This designation is based on functional equivalence across all critical electrical and mechanical parameters, combined with RJSAE538908's active product status from Amphenol ICC Commercial Products.

Compliance Considerations: Both components maintain RoHS Compliance and MSL 1 (Unlimited) ratings, ensuring regulatory compatibility for manufacturing and environmental applications.

Active Supply Advantage: RJSAE538908 carries active product status, providing assured long-term availability and manufacturing support, whereas RJSNEJF8908 (obsolete status) faces potential supply constraints.

Enhanced Features: The RJSAE538908 substitute includes an EMI Finger feature in its shielding design and offers superior contact finish thickness (50.0µin vs. 30.0µin) and an expanded operating temperature range (-55°C lower limit vs. -40°C). These enhancements do not affect backward compatibility but provide improved performance margins in electromagnetic interference environments and extreme temperature applications.

Frequently Asked Questions (FAQ)

Q: Can RJSAE538908 directly replace RJSNEJF8908 in existing designs? A: Yes. Both connectors share identical core specifications for connector type, pin configuration (8p8c RJ45 Ethernet), mounting (Through Hole), orientation (90° right-angle), termination method (Solder), contact materials (Phosphor Bronze with Gold finish), and housing construction. The RJSAE538908 is the formal substitute designation.

Q: Why does RJSAE538908 have a thicker gold contact finish (50.0µin vs. 30.0µin)? A: The increased contact finish thickness in RJSAE538908 (1.27µm vs. 0.76µm) enhances contact durability and wear resistance without altering electrical characteristics or mechanical fit. This is functionally compatible and represents an improvement over the original specification.

Q: What is the significance of the EMI Finger feature in RJSAE538908? A: The EMI Finger is an enhanced shielding element included in RJSAE538908. It improves electromagnetic interference rejection compared to the basic shielded design of RJSNEJF8908. This feature does not prevent substitution and provides additional protection in electrically noisy environments.

Q: Are the operating temperature ranges compatible? A: Yes. RJSAE538908 supports -55°C to 85°C, whereas RJSNEJF8908 supports -40°C to 85°C. The expanded lower temperature range in the substitute is fully backward-compatible and permits use in more extreme cold-temperature applications.

Q: What packaging consideration exists between these two parts? A: RJSNEJF8908 packaging information is not specified in the documentation. RJSAE538908 is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes when transitioning to the substitute.

Q: Why is RJSNEJF8908 marked as obsolete? A: The RJSNEJF8908 is listed as obsolete product status by Amphenol ICC, indicating discontinued production and limited long-term availability. RJSAE538908, with active product status, ensures reliable supply for new designs and ongoing production requirements.

Q: Are both components RoHS compliant? A: Yes. Both RJSNEJF8908 and RJSAE538908 carry RoHS Compliance certification, satisfying environmental and regulatory requirements for electronic component manufacturing.

Q: What is the inventory status? A: RJSNEJF8908 has 1163 pieces listed as new original stock; RJSAE538908 has 842 pieces available. However, given obsolete status for RJSNEJF8908, the active-status RJSAE538908 provides assured long-term procurement sustainability.
