Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJ088A8 is determined by compatibility across the following critical parameters:

• Connector Type: Must be Jack configuration for RJ45 modular connections
• Contact Configuration: Must maintain 8p8c (RJ45/Ethernet) pinout and port count
• Mounting Type: Must support through-hole solder termination
• Orientation: Must provide 90° right-angle mounting
• Environmental Rating: Operating temperature range must accommodate -40°C to 85°C minimum
• Compliance: RoHS compliance required for equivalent selection

The substitute part RJSAEGF88A8 meets these core compatibility criteria. The primary difference is shielded versus unshielded configuration; the substitute offers enhanced EMI protection suitable for environments with increased electromagnetic interference concerns.

Parameter Comparison

Engineering Selection Recommendations

The RJSAEGF88A8 serves as a direct functional equivalent for the obsolete RJSNEJ088A8 based on identical core mechanical and electrical specifications. The substitute maintains RoHS compliance and is currently in active production status, ensuring supply chain availability.

Key distinctions affecting selection:

• The substitute provides shielded configuration, offering superior electromagnetic interference rejection compared to the original unshielded design
• Operating temperature range extends to -55°C minimum versus -40°C for the original part, providing enhanced performance in cold environments
• Contact finish thickness differs (15.0µin versus 30.0µin), with the substitute employing a thinner gold layer
• The substitute is actively manufactured, eliminating obsolescence concerns associated with the original part number

For PCB layouts and mechanical mounting, the identical orientation (90° right-angle) and through-hole solder termination ensure drop-in compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can the RJSAEGF88A8 replace the RJSNEJ088A8 in existing designs? The RJSAEGF88A8 provides identical mounting footprint, connector orientation, and solder termination. Electrical compatibility is confirmed through matching contact configuration (8p8c RJ45). The shielded design of the substitute may require additional PCB trace grounding considerations in designs originally specified for unshielded operation.

Q: What are the implications of the shielded versus unshielded difference? The main part features unshielded construction, while the substitute includes shielding. This difference does not affect mechanical or pin compatibility. Shielding provides EMI rejection beneficial in industrial or high-interference environments. Designs not requiring shielding can use the unshielded substitute without functional impact, though supply is now constrained to the active product.

Q: Are there compatibility concerns with the contact finish thickness difference? Contact finish specifications (30.0µin versus 15.0µin gold plating) do not affect electrical performance or mechanical fit. Both thicknesses meet industry standards for RJ45 connector durability and contact resistance. The thinner finish on the substitute reflects current manufacturing practices and carries no operational implications.

Q: How does the extended temperature range on the substitute affect selection? The substitute operates from -55°C to 85°C versus -40°C to 85°C for the original part. This represents an expanded operational envelope. Designs originally specified for the -40°C to 85°C range remain fully compatible with the substitute, which exceeds those requirements.

Q: Is supply chain continuity ensured with this substitute? The substitute (RJSAEGF88A8) carries active product status from Amphenol ICC with 763 units in stock, versus the obsolete status of the original part. This ensures long-term availability and manufacturing continuity for new production runs and repair applications.
