RJSNEJ08KA8 Equivalent & Substitute Parts

Part Overview

The RJSNEJ08KA8 is a jack modular connector manufactured by Amphenol ICC (Commercial Products) in the RJSNE series. This 8p8c (RJ45, Ethernet) connector features a 90° right-angle orientation, unshielded design, and through-hole solder termination. The part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical and mechanical compatibility while meeting current product availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJ08KA8 is based on strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Number of Ports: 8
• Number of Rows: 2
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation Parameters:

• Shielding: The main part is unshielded; substitutes may include shielded variants with EMI fingers for enhanced electromagnetic interference protection
• Contact Finish Thickness: Variation permitted within gold plating specifications
• Operating Temperature Range: Substitutes may extend the upper or lower temperature limits
• LED Color: Variation in indicator LED color is permitted
• Tab Direction: Variation in tab orientation is permitted
• Product Status: Active substitutes are preferred for obsolete parts

The RJSAE538EA8 qualifies as a substitute based on these criteria, with the primary difference being the addition of shielding and EMI finger protection.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538EA8 is the qualified substitute for the obsolete RJSNEJ08KA8. Both parts maintain identical electrical and mechanical specifications for the core 8p8c RJ45 jack connector function, including connector type, contact configuration, mounting method, and termination approach.

The RJSAE538EA8 offers the following advantages:

Product Status: The substitute is classified as Active, ensuring continued availability and manufacturing support, whereas the main part is Obsolete.

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

Enhanced Specifications: The substitute provides extended lower operating temperature range (-55°C versus -40°C) and increased contact finish thickness (50.0µin versus 30.0µin), supporting broader environmental and durability requirements.

Shielding Enhancement: The addition of shielding and EMI finger protection in the substitute provides electromagnetic interference mitigation for applications requiring enhanced signal integrity, while maintaining full backward compatibility with unshielded connector footprints and pinout configurations.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538EA8 be used as a direct replacement for the RJSNEJ08KA8?

A: Yes. Both connectors share identical core specifications: 8p8c RJ45 jack configuration, 90° right-angle orientation, through-hole solder termination, phosphor bronze gold-plated contacts, and thermoplastic housing. The primary difference is the addition of shielding and EMI finger protection in the substitute, which does not prevent mechanical or electrical compatibility.

Q: What is the impact of the shielding difference?

A: The RJSNEJ08KA8 is unshielded, while the RJSAE538EA8 includes shielding with EMI finger protection. Shielding provides electromagnetic interference mitigation and is beneficial in environments with high-frequency noise or sensitive signal applications. The shielded variant does not compromise compatibility with standard RJ45 connector interfaces.

Q: Are there differences in contact finish specifications?

A: Yes. The RJSNEJ08KA8 has a contact finish thickness of 30.0µin (0.76µm), while the RJSAE538EA8 has 50.0µin (1.27µm). The increased thickness in the substitute provides enhanced durability and contact reliability over extended operational life.

Q: Does the extended operating temperature range of the substitute affect compatibility?

A: No. The RJSAE538EA8 extends the lower operating temperature limit to -55°C (compared to -40°C for the main part), while maintaining the same upper limit of 85°C. This extended range provides greater environmental flexibility without affecting compatibility in applications within the original -40°C ~ 85°C specification.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNEJ08KA8 and RJSAE538EA8 are RoHS Compliant with identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly.

Q: Why is the main part classified as Obsolete?

A: The RJSNEJ08KA8 is classified as Obsolete, meaning it is no longer in active production. The RJSAE538EA8 is the active equivalent that provides continued availability and manufacturing support for new designs and production requirements.
