RJSNE508L08

Part Overview

The RJSNE508L08 is a modular jack connector designed for 8p8c (RJ45, Ethernet) applications with a 90° right-angle orientation and through-hole solder termination. This connector features unshielded construction with integrated LED indicators (green, yellow, and red) and is manufactured by Amphenol ICC (Commercial Products). The product is currently listed as obsolete, necessitating identification of compatible active alternatives to maintain design flexibility and ensure long-term component availability for new designs or sustaining engineering applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete RJSNE508L08 is based on compatibility across the following critical parameters:

• Connector Type & Configuration: Both the main part and substitute maintain jack connector topology with 8p8c (RJ45, Ethernet) contact arrangement
• Mechanical Form Factor: Identical through-hole mounting, 90° right-angle orientation, and solder termination ensure PCB layout compatibility
• Electrical Performance: Matching contact material (phosphor bronze), finish (gold at 50.0µin/1.27µm), and unshielded construction preserve signal integrity and contact resistance characteristics
• Environmental Specifications: Operating temperature range, RoHS compliance, and MSL rating determine thermal and reliability suitability
• Functional Features: LED indicator presence (green, yellow, red) and tab direction (up and down) maintain visual feedback and mechanical engagement consistency

The RJSAE508L08 qualifies as a direct substitute based on these aligned electrical and mechanical parameters, despite product status differences and operating temperature range variation.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE508L08 serves as the qualified substitute for the obsolete RJSNE508L08, with the following engineering basis:

Compliance & Availability: The substitute maintains RoHS compliance, ensuring regulatory alignment with modern electronics manufacturing standards. The active product status of RJSAE508L08 provides assured long-term supply and manufacturing continuity.

Thermal Performance Consideration: The operating temperature range narrows from -40°C to 85°C (RJSNE508L08) to -40°C to 70°C (RJSAE508L08). Applications operating above 70°C require design review to confirm thermal margin adequacy.

Electrical & Mechanical Equivalence: Identical contact material, finish specification, connector topology, and mounting characteristics ensure functional interchangeability for standard Ethernet and modular connector applications. Pin-to-pin compatibility is maintained across all 8p8c contact positions.

Frequently Asked Questions (FAQ)

Q: Can RJSAE508L08 be used as a direct replacement for RJSNE508L08 in existing designs?

A: Yes, the RJSAE508L08 provides direct substitution for connector footprint, termination method, and electrical performance. Design review is required only if the application operates above 70°C, as the substitute has a lower upper operating temperature limit.

Q: Are there differences in contact resistance or signal integrity between these parts?

A: No. Both connectors use identical phosphor bronze contact material with 50.0µin (1.27µm) gold finish, resulting in equivalent contact resistance and signal transmission characteristics for RJ45 Ethernet applications.

Q: Why is the MSL rating different between the two parts?

A: The RJSNE508L08 carries MSL 1 (unlimited), while RJSAE508L08 lists MSL as Not Applicable. This difference does not affect substitution in standard manufacturing environments. The Not Applicable designation for the active part reflects current industry classification practices and does not indicate reduced moisture tolerance.

Q: What is the significance of the different series designations (RJSNE versus RJSAE)?

A: Series designation reflects Amphenol ICC's internal product line organization and does not indicate functional differences for the specified parameters. Both parts are manufactured to the same connector standards for 8p8c applications.

Q: Are the LED color indicators identical across both parts?

A: Yes. Both RJSNE508L08 and RJSAE508L08 include integrated LED indicators with green, yellow, and red color options, maintaining identical visual feedback functionality.
