RJSNEJ08HA8 Equivalent & Substitute Parts

Part Overview

The RJSNEJ08HA8 is a Jack Modular Connector (8p8c RJ45/Ethernet) manufactured by Amphenol ICC with 90° right-angle orientation and unshielded configuration. This component is classified as Obsolete, indicating that original production has been discontinued. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and provide functional alternatives for applications where the original part is no longer readily available or where design requirements may benefit from enhanced specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the RJSNEJ08HA8 is evaluated based on the following critical parameters that define functional compatibility:

Essential Parameters for Substitution:

• Connector Type: Jack (fixed)
• Contact Configuration: 8p8c (RJ45, Ethernet) - 8 positions, 8 contacts (fixed)
• Orientation: 90° Angle (Right) (fixed)
• Mounting Type: Through Hole (fixed)
• Termination Method: Solder (fixed)
• Contact Material: Phosphor Bronze (fixed)

Allowable Variation Parameters:

• Shielding: May differ (Unshielded vs. Shielded with EMI Finger)
• Contact Finish Thickness: May increase (0.76µm to 1.27µm)
• Operating Temperature Range: May expand (additional lower/upper limits)
• Product Status: Active preferred over Obsolete
• Compliance Certifications: RoHS Compliant (consistent across parts)

The RJSAE538H08 qualifies as a substitute because it maintains all essential parameters while offering enhanced specifications in shielding and thermal performance.

Parameter Comparison

Engineering Selection Recommendations

The RJSNE series (RJSNEJ08HA8) is classified as Obsolete. The RJSAE538H08 is classified as Active and serves as the direct substitute for discontinued designs.

Key Advantages of RJSAE538H08:

1. Active Product Status: Ensures ongoing manufacturing availability and supply chain continuity.
2. Enhanced EMI Protection: Shielded configuration with EMI Finger provides electromagnetic interference rejection superior to the unshielded original design.
3. Improved Thermal Range: Operating temperature lower limit extended from -40°C to -55°C.
4. Increased Contact Durability: Gold plating thickness increased from 0.76µm to 1.27µm, providing enhanced wear resistance and connection reliability.
5. Regulatory Compliance: Maintains RoHS compliance and identical ECCN/HTSUS classifications.

Both components are manufactured by Amphenol ICC (Commercial Products) and share identical pin configurations, mounting geometry, and fundamental electrical characteristics. Substitution requires verification that PCB footprints accommodate the shielded EMI Finger feature of the RJSAE538H08.

Frequently Asked Questions (FAQ)

Q: Is the RJSAE538H08 a true drop-in replacement for the RJSNEJ08HA8?

A: The RJSAE538H08 maintains identical pin count (8p8c), contact configuration, orientation (90° right-angle), mounting type (through-hole), and termination method (solder). Physical dimensions of the connector body are compatible. However, the presence of the EMI Finger shield in the RJSAE538H08 requires PCB layout verification to ensure proper spacing and clearance.

Q: What are the differences in shielding between these parts?

A: The RJSNEJ08HA8 is unshielded and provides no EMI rejection. The RJSAE538H08 is shielded with an EMI Finger feature, which provides electromagnetic interference suppression. For applications requiring EMI immunity, the shielded variant is superior.

Q: How do the operating temperature ranges compare?

A: The RJSNEJ08HA8 operates from -40°C to 85°C. The RJSAE538H08 extends the lower limit to -55°C to 85°C, providing 15°C additional cold temperature operation capability.

Q: Are there differences in contact finish durability?

A: Yes. The RJSNEJ08HA8 has 0.76µm gold plating on phosphor bronze contacts. The RJSAE538H08 has 1.27µm gold plating on identical phosphor bronze contacts, providing increased wear resistance and contact longevity.

Q: Is the PCB footprint identical between these parts?

A: Both parts use through-hole mounting with identical contact positioning for 8p8c RJ45 standard. PCB design verification is required to accommodate the EMI Finger shield dimensions in the RJSAE538H08.

Q: Does substitution affect regulatory compliance?

A: No. Both parts share identical RoHS compliance status, ECCN classification (EAR99), HTSUS code (8536.69.4040), and Moisture Sensitivity Level (MSL 1 - Unlimited).

Q: Why is the original RJSNEJ08HA8 marked as Obsolete?

A: Obsolete status indicates that Amphenol ICC has discontinued manufacturing of the RJSNE series. The RJSAE series represents the current manufacturing line for equivalent 90° right-angle RJ45 jack connectors with enhanced performance specifications.
