RJSNEJ084A8

Part Overview

The RJSNEJ084A8 is a modular jack connector conforming to the 8p8c (RJ45, Ethernet) standard, manufactured by Amphenol ICC (Commercial Products). This unshielded, right-angle (90°) through-hole connector features solder termination and is rated for operating temperatures between -40°C and 85°C. The product is classified as obsolete, necessitating identification of equivalent substitute parts to maintain design continuity and ensure ongoing component availability for applications requiring this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJ084A8 is determined by strict adherence to the following core parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder

Allowable Variation Parameters:

• Shielding: The original RJSNEJ084A8 is unshielded. Substitutes may incorporate shielding with EMI fingers, provided all other electrical and mechanical parameters remain compatible and the connector maintains RJ45/8p8c electrical compliance.
• Contact Finish Thickness: Variations in gold plating thickness (0.76µm versus 1.27µm) are permissible within industry standards for 8p8c connectors.
• Operating Temperature Range: Substitute parts with extended operating ranges (-55°C to 85°C) are acceptable for applications currently operating within the RJSNEJ084A8 limits.
• Product Status: Active substitutes are appropriate replacements for obsolete parts.

The RJSAE538408 qualifies as a valid substitute based on these criteria, despite the introduction of EMI shielding, which enhances performance without compromising compatibility with standard RJ45 installations.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538408 is the approved substitute for the obsolete RJSNEJ084A8. Both parts are manufactured by Amphenol ICC and maintain RoHS compliance. The RJSAE538408 offers the following advantages: active product status ensuring ongoing availability, extended operating temperature range (-55°C minimum versus -40°C), enhanced shielding with EMI fingers for improved signal integrity, and increased contact finish thickness providing extended connector lifespan.

Designs currently utilizing the RJSNEJ084A8 can incorporate the RJSAE538408 without modification to PCB footprints or mating connectors, as mechanical and electrical pin compatibility is maintained across all 8p8c RJ45 standard implementations. The introduction of shielding in the substitute part provides performance benefits in environments subject to electromagnetic interference without introducing incompatibility concerns.

Frequently Asked Questions (FAQ)

Q: Are RJSNEJ084A8 and RJSAE538408 pin-compatible? A: Yes. Both connectors conform to the 8p8c (RJ45, Ethernet) standard with identical pin configurations, contact materials, and solder termination methods. Pin-to-pin replacement is supported.

Q: What is the difference in shielding between these connectors? A: The RJSNEJ084A8 is unshielded, while the RJSAE538408 incorporates shielding with EMI fingers. Shielding provides enhanced electromagnetic interference rejection. Both designs maintain standard RJ45 mechanical and electrical compatibility.

Q: Can the RJSAE538408 be used in applications originally designed for the unshielded RJSNEJ084A8? A: Yes. The RJSAE538408 meets all dimensional, mechanical, and electrical requirements of the 8p8c standard. The added shielding feature does not introduce incompatibility and generally improves performance characteristics.

Q: What is the significance of the contact finish thickness difference? A: The RJSAE538408 features 50.0µin (1.27µm) gold plating compared to 30.0µin (0.76µm) on the RJSNEJ084A8. Increased plating thickness typically provides enhanced wear resistance and extended connector service life under repeated mating cycles.

Q: Are both connectors RoHS compliant? A: Yes. Both RJSNEJ084A8 and RJSAE538408 are RoHS compliant with Moisture Sensitivity Level 1 (Unlimited), suitable for standard component handling and storage conditions.

Q: What are the packaging differences? A: The RJSNEJ084A8 packaging information is not specified in the provided data. The RJSAE538408 is supplied in Tray packaging. Verify packaging requirements with your procurement specifications if bulk component handling procedures are defined.

Q: Which part should be selected for new designs? A: The RJSAE538408 should be selected for new designs due to its active product status and continued manufacturer support. The RJSNEJ084A8 is obsolete and should be replaced in existing designs when component refresh cycles occur.
