RJSNEJF8N08 Equivalent & Substitute Parts

Part Overview

The RJSNEJF8N08 is a modular jack connector manufactured by Amphenol ICC (Commercial Products) conforming to the 8p8c (RJ45, Ethernet) standard with 90° right-angle orientation and shielding. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance, legacy design support, and procurement planning. Equivalent alternatives must maintain functional compatibility through matching connector type, contact count, mounting configuration, and electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the RJSNEJF8N08 is determined by the following critical parameters: connector type (jack), contact count (8p8c), mounting configuration (through hole, solder termination), mechanical orientation (90° right-angle), and shielding provision. The substitute part RJSAE538B08 maintains equivalence across these core parameters, enabling drop-in replacement in applications requiring identical form factor and electrical interface.

Parameter Comparison

Engineering Selection Recommendations

The RJSNEJF8N08 is classified as obsolete; therefore, the RJSAE538B08 is the designated substitute for ongoing production and service applications. The RJSAE538B08 is active in the product portfolio and carries identical RoHS compliance certification. The substitute provides enhanced EMI shielding through integrated EMI fingers and operates across an extended lower temperature range (-55°C vs. -40°C), offering superior environmental robustness. The increased contact finish thickness (50.0µin vs. 30.0µin) in the substitute enhances contact durability and wear resistance, making it suitable for high-cycle insertion/extraction applications.

Frequently Asked Questions (FAQ)

Q: Can RJSAE538B08 replace RJSNEJF8N08 in existing designs? A: Yes. Both connectors maintain identical pin count (8p8c), mounting configuration (through hole, solder termination), mechanical orientation (90° right-angle), and shielding architecture, ensuring mechanical and electrical compatibility. The substitute's enhanced EMI filtering and extended temperature specification provide additional performance margin.

Q: What is the difference in shielding between these connectors? A: The RJSNEJF8N08 provides shielding. The RJSAE538B08 provides shielding with integrated EMI fingers, offering enhanced electromagnetic interference suppression suitable for high-speed Ethernet and noise-sensitive applications.

Q: Are there packaging differences between the original and substitute? A: The RJSNEJF8N08 packaging information is not specified in the documentation. The RJSAE538B08 is supplied in tray packaging. Inventory verification and procurement lead time assessment are necessary when transitioning to the substitute component.

Q: Does the contact finish thickness difference affect compatibility? A: No. The increased contact finish thickness (50.0µin on the substitute vs. 30.0µin on the original) improves contact longevity and wear characteristics without affecting electrical interface compatibility or mechanical fit. Both utilize identical phosphor bronze substrate material with gold plating.

Q: What is the operating temperature difference, and does it matter? A: The RJSAE538B08 extends the lower operating limit to -55°C compared to -40°C on the original. This extended range provides additional environmental tolerance. If your application operates exclusively within the original temperature range (-40°C to 85°C), both connectors are functionally equivalent in this parameter.
