Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJF8BA8 is based on strict equivalence of the following critical parameters:

• Connector Type & Contact Configuration: Jack connector with 8p8c (RJ45, Ethernet) contact arrangement
• Physical Orientation: 90° right-angle mounting orientation
• Mounting & Termination: Through-hole solder termination
• Shielding Architecture: Shielded construction for EMI protection
• Contact Materials & Finish: Phosphor bronze contacts with gold plating
• Housing Material: Thermoplastic construction
• Environmental Compliance: RoHS compliance and MSL 1 rating

The RJSAE538B08 meets all these core substitution criteria while offering enhanced specifications in contact finish thickness and extended operating temperature range. Both connectors share identical connector type, contact configuration, orientation, mounting method, termination style, and housing material.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538B08 is the direct active equivalent for the obsolete RJSNEJF8BA8. Selection of the RJSAE538B08 is supported by the following factors:

Product Status: The RJSAE538B08 maintains active product status with current manufacturing availability, whereas the RJSNEJF8BA8 is obsolete and subject to discontinuation.

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

Enhanced Specifications: The RJSAE538B08 provides improved contact finish thickness (50.0µin versus 30.0µin) and extended lower operating temperature limit (-55°C versus -40°C), offering superior performance margins without compromising compatibility.

Electrical & Mechanical Compatibility: Identical connector type, contact configuration, orientation, mounting method, termination style, shielding approach, and housing material ensure direct functional substitution in existing circuit board designs and assemblies.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538B08 be used as a direct replacement for the RJSNEJF8BA8 in existing designs?

A: Yes. Both connectors share identical connector type (jack), contact configuration (8p8c RJ45), orientation (90° right-angle), mounting method (through-hole solder), shielding (shielded), and housing material (thermoplastic). The RJSAE538B08 is electrically and mechanically compatible with designs specified for the RJSNEJF8BA8.

Q: What is the difference between the shielding specifications of these two connectors?

A: The RJSNEJF8BA8 features standard shielding, while the RJSAE538B08 includes shielding with an EMI finger. The EMI finger provides enhanced electromagnetic interference suppression without affecting mechanical or electrical compatibility.

Q: Why is the contact finish thickness different between these parts?

A: The RJSAE538B08 specifies 50.0µin (1.27µm) gold plating compared to 30.0µin (0.76µm) on the RJSNEJF8BA8. The increased thickness on the active equivalent provides enhanced durability and contact reliability over extended operational life.

Q: Are there any temperature range limitations when substituting the RJSAE538B08?

A: The RJSAE538B08 operates across -55°C to 85°C, which encompasses the -40°C to 85°C range of the RJSNEJF8BA8. The extended lower temperature capability of the substitute part presents no operational constraints for applications within the original temperature specification.

Q: What packaging differences exist between these connectors?

A: The RJSNEJF8BA8 packaging is not specified in the available data. The RJSAE538B08 is supplied in tray packaging. Packaging format does not affect electrical or mechanical compatibility and is a logistics consideration only.

Q: Are both connectors RoHS compliant?

A: Yes. Both the RJSNEJF8BA8 and RJSAE538B08 maintain RoHS compliance status and identical moisture sensitivity level (MSL 1, Unlimited), ensuring environmental and regulatory equivalence.
