RJSNEG08BA8 Equivalent & Substitute Parts

Part Overview

The RJSNEG08BA8 is a Jack Modular Connector with 8p8c (RJ45, Ethernet) configuration, featuring 90° right-angle orientation and unshielded design. Manufactured by Amphenol ICC (Commercial Products), this connector is designated as obsolete product status. Due to its obsolete classification, identifying functionally equivalent active alternatives is essential for ongoing system support, design continuations, and supply chain planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for modular connectors in the 8p8c (RJ45, Ethernet) category is determined by the following critical parameters:

• Connector Type & Contact Configuration: Both main and substitute parts must be Jack type connectors with 8p8c (RJ45, Ethernet) positioning
• Mechanical Form Factor: 90° right-angle orientation with through-hole mounting and solder termination are required equivalents
• Electrical Properties: Unshielded design specification must be maintained
• Environmental Compliance: RoHS compliance and MSL rating ensure regulatory and handling consistency
• Physical Interface: Contact material, housing material, and tab direction must align for PCB integration

The substitute part RJSAE508B08 satisfies all these parameters, representing a direct functional replacement with enhanced environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE508B08 serves as the primary active substitute for the obsolete RJSNEG08BA8. Both connectors maintain identical functional and mechanical specifications across all critical parameters, ensuring drop-in compatibility for PCB design and assembly.

Key distinctions:

• Product Status: RJSAE508B08 holds Active product status, providing assured long-term availability and manufacturing continuity compared to the obsolete RJSNEG08BA8
• Temperature Performance: RJSAE508B08 extends the minimum operating temperature to -55°C, offering enhanced thermal range capability
• Contact Finish Thickness: RJSAE508B08 specifies 50.0µin (1.27µm) gold finish versus 15.0µin (0.38µm) on the main part, providing increased contact durability
• Regulatory Compliance: Both parts maintain RoHS compliance and MSL 1 rating, meeting standard manufacturing and environmental requirements

The RJSAE508B08 is the recommended replacement for new designs and ongoing production of legacy systems using RJSNEG08BA8.

Frequently Asked Questions (FAQ)

Q: Can RJSAE508B08 directly replace RJSNEG08BA8 in existing designs?

A: Yes. Both connectors share identical contact configurations (8p8c RJ45), mechanical form factors (90° right-angle through-hole solder mount), and electrical properties (unshielded design). Physical footprints and pin assignments are equivalent.

Q: What is the significance of the different operating temperature ranges?

A: RJSAE508B08 specifies -55°C minimum operating temperature versus -40°C for RJSNEG08BA8. This extended range does not restrict use in applications originally designed for the main part. Designers requiring temperatures below -40°C benefit from the substitute's expanded specification.

Q: How do the contact finish specifications differ?

A: RJSNEG08BA8 has 15.0µin (0.38µm) gold plating, while RJSAE508B08 has 50.0µin (1.27µm). The thicker gold plating on the substitute reduces contact wear and extends connector life, particularly in high-cycle mating applications.

Q: Are there packaging differences between these parts?

A: RJSNEG08BA8 is supplied without specified packaging notation, while RJSAE508B08 is packaged in Trays. Packaging affects storage, handling, and procurement logistics but does not impact functional performance or mechanical compatibility.

Q: What compliance certifications apply to both parts?

A: Both connectors are RoHS Compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. Both hold the same ECCN (EAR99) and HTSUS (8536.69.4040) classifications, supporting equivalent regulatory and export documentation.

Q: Why is RJSNEG08BA8 marked as obsolete?

A: Obsolete product status indicates the manufacturer has discontinued active production and support. The active substitute RJSAE508B08 ensures design continuity without functional or mechanical compromise.
