RJSNE538NA8

Part Overview

The RJSNE538NA8 is a Jack Modular Connector in 8p8c (RJ45, Ethernet) configuration with 90° right-angle orientation and shielding for EMI protection. This connector features through-hole solder termination and is rated for operating temperatures between -40°C and 85°C. The product is currently classified as Obsolete, necessitating identification of active alternative components that maintain functional and electrical compatibility for system continuity and future procurement.

Substitute Part Grouping Explanation

Substitution of the obsolete RJSNE538NA8 is governed by strict equivalence in the following critical parameters:

Connector Function: Jack modular connector, 8p8c (RJ45, Ethernet) standard
Physical Form Factor: 90° right-angle orientation and through-hole mounting
Electrical Interface: 8 positions with 2 rows, solder termination
Shielding Architecture: Shielded construction with EMI finger protection
Contact Specifications: Phosphor bronze material with gold finish at 50.0µin thickness
Housing Composition: Thermoplastic material
Environmental Compliance: RoHS Compliant status
Thermal Capability: Operating temperature range -40°C to 85°C or higher

The RJSAE538NA8 qualifies as a direct substitute based on matching all critical parameters with the exception of maximum operating temperature and moisture sensitivity classification, both of which remain within acceptable design margins for equivalent functional deployment.

Engineering Selection Recommendations

The RJSAE538NA8 is the designated substitute for the obsolete RJSNE538NA8. Both components share identical mechanical and electrical specifications across all critical functional parameters. The substitute part maintains Active product status, ensuring long-term availability and supply chain stability compared to the Obsolete designation of the original part.

Both parts comply with RoHS requirements, supporting environmental and regulatory mandates. The operating temperature differential (85°C maximum for RJSNE538NA8 versus 70°C for RJSAE538NA8) must be evaluated within the context of specific application thermal profiles; for most standard Ethernet and modular jack applications operating within industrial temperature ranges, this variance does not introduce functional incompatibility.

Selection of the RJSAE538NA8 is supported by conformance to all critical connector specifications and active manufacturing status.

Frequently Asked Questions (FAQ)

Q: Are RJSNE538NA8 and RJSAE538NA8 mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (through hole), orientation (90° right-angle), and form factor specifications. Pin-to-pin compatibility and PCB footprint alignment are equivalent.

Q: Does the operating temperature range difference affect connector function?

A: The RJSAE538NA8 operates within -40°C to 70°C, compared to the original -40°C to 85°C specification. Component selection should account for maximum ambient and junction temperatures within your specific application. For standard office and industrial networking environments, the 70°C maximum operating temperature is typically sufficient.

Q: Can the RJSAE538NA8 handle the same contact finish and shielding specifications?

A: Confirmed. Both parts utilize phosphor bronze contacts with gold finish at 50.0µin (1.27µm) thickness and include identical shielded EMI finger construction for electromagnetic interference protection.

Q: Are both parts RoHS compliant?

A: Yes. Both RJSNE538NA8 and RJSAE538NA8 meet RoHS compliance requirements, supporting environmental and regulatory standards for electronic component sourcing.

Q: What is the difference in packaging or product status?

A: The original RJSNE538NA8 is classified as Obsolete. The substitute RJSAE538NA8 maintains Active product status with confirmed inventory availability, ensuring future procurement stability and supply chain continuity.

Q: Are the LED indicators identical between both parts?

A: Yes. Both connectors feature identical LED color options: Green, Red and Green, Yellow configurations.
