RJSNEJF8JA8 Modular Connector Jack 8P8C RJ45 Equivalent & Substitute Parts

Part Overview

The RJSNEJF8JA8 is a shielded modular jack connector manufactured by Amphenol ICC (Commercial Products), designed for 8-position 8-contact (8P8C) RJ45 Ethernet applications. This connector features a 90° right-angle orientation with through-hole solder termination and integrated board lock mechanism. The product is classified as obsolete, necessitating identification of active equivalent components for ongoing design and procurement requirements. Substitute parts must maintain electrical and mechanical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJF8JA8 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Contact Configuration: 8P8C (RJ45, Ethernet)
• Number of Ports: 8
• Number of Rows: 2
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination Method: Solder
• Shielding: Shielded
• Tab Direction: Up and Down
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• RoHS Compliance: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The RJSAE538B08 satisfies all mandatory matching parameters and qualifies as a direct substitute. This part is manufactured by the same supplier (Amphenol ICC Commercial Products) and maintains functional and mechanical equivalence while offering active product status and enhanced specifications.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538B08 is the qualified substitute for the obsolete RJSNEJF8JA8. Selection rationale is based on the following engineering criteria:

Product Status: The RJSAE538B08 maintains active product status, ensuring continued availability, manufacturing support, and compliance with current industry standards. The RJSNEJF8JA8 is classified as obsolete and subject to discontinuation.

Compliance and Certifications: Both parts maintain RoHS compliance and identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming regulatory equivalence.

Electrical and Mechanical Compatibility: The substitute part maintains all critical parameters including connector type, contact configuration, mounting orientation, termination method, and shielding architecture. Through-hole solder termination and board lock features are preserved.

Enhanced Specifications: The RJSAE538B08 provides extended operating temperature range (-55°C to 85°C versus -40°C to 85°C) and increased contact finish thickness (50.0µin versus 30.0µin), offering improved durability and environmental performance.

EMI Enhancement: The substitute incorporates EMI finger shielding, providing additional electromagnetic interference mitigation beyond the base shielded configuration.

Frequently Asked Questions (FAQ)

Q: Can RJSAE538B08 be used as a direct replacement for RJSNEJF8JA8 in existing designs?

A: Yes. The RJSAE538B08 maintains functional and mechanical equivalence across all critical parameters including connector type, contact configuration, mounting type, orientation, termination method, and shielding. PCB footprint and solder pad layout are compatible.

Q: What are the differences between these two parts?

A: The primary differences are: (1) Product Status—RJSAE538B08 is active while RJSNEJF8JA8 is obsolete; (2) Operating Temperature Range—RJSAE538B08 extends to -55°C minimum versus -40°C; (3) Contact Finish Thickness—RJSAE538B08 provides 50.0µin versus 30.0µin; (4) Shielding—RJSAE538B08 includes EMI finger enhancement; (5) LED Color Configuration—RJSAE538B08 offers Red/Green on both sides versus Red/Green-Yellow.

Q: Are there packaging differences?

A: The RJSNEJF8JA8 packaging specification is not provided in the data. The RJSAE538B08 is supplied in Tray packaging. Verify packaging requirements for your procurement process.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both RJSNEJF8JA8 and RJSAE538B08 are RoHS Compliant with identical Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: What is the significance of the EMI Finger feature in RJSAE538B08?

A: The EMI Finger provides additional shielding effectiveness for electromagnetic interference suppression. This is an enhancement over the base shielded configuration and does not affect mechanical compatibility or pin assignment.

Q: Are the contact materials and finishes identical?

A: Contact material (Phosphor Bronze) and finish type (Gold) are identical. Contact finish thickness differs: RJSAE538B08 provides 50.0µin (1.27µm) versus RJSNEJF8JA8 at 30.0µin (0.76µm), offering enhanced wear resistance and contact durability.

Q: What is the inventory status for these parts?

A: RJSNEJF8JA8 shows 669 pieces in stock (obsolete status). RJSAE538B08 shows 863 pieces in stock (active status). Verify current availability with your supplier for procurement planning.
