RJSNEJ38VA8 Equivalent & Substitute Parts

Part Overview

The RJSNEJ38VA8 is a modular jack connector manufactured by Amphenol ICC (Commercial Products), designed for 8p8c (RJ45, Ethernet) applications with 90° right-angle orientation and shielded construction. This connector features through-hole solder termination, board lock functionality, and dual-color LED indicators (Red, Green).

The RJSNEJ38VA8 carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ38VA8 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Contact Configuration: 8p8c (RJ45, Ethernet)
• Orientation: 90° Angle (Right)
• Mounting Type: Through Hole
• Termination Method: Solder
• Shielding: Shielded, EMI Finger
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• RoHS Compliance: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The RJSAE538B08 qualifies as a substitute part because it maintains identical values across all mandatory parameters. Variations in contact finish thickness, operating temperature range, LED color options, and product status do not preclude substitution when the core electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538B08 is the qualified substitute for the obsolete RJSNEJ38VA8 based on the following engineering criteria:

Compliance and Certification: Both parts maintain RoHS compliance and identical Moisture Sensitivity Level (MSL 1), ensuring regulatory and environmental compatibility across applications.

Electrical and Mechanical Equivalence: Core specifications for connector type, contact configuration, orientation, mounting, termination, shielding, contact material, and finish are identical. These parameters define functional interchangeability in circuit board applications.

Product Status Advantage: The RJSAE538B08 carries active product status, providing assured long-term availability and supply chain continuity compared to the obsolete RJSNEJ38VA8.

Parameter Variations: The RJSAE538B08 features increased contact finish thickness (50.0µin versus 30.0µin) and an extended lower operating temperature limit (-55°C versus -40°C). These variations represent enhanced performance characteristics that do not compromise backward compatibility.

Selection of the RJSAE538B08 is appropriate for new designs, production continuity, and field replacements where the RJSNEJ38VA8 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538B08 directly replace the RJSNEJ38VA8 in existing designs?

A: Yes. The RJSAE538B08 maintains identical connector type, contact configuration, orientation, mounting type, termination method, shielding, contact material, and finish. These parameters define functional equivalence for through-hole solder applications. The increased contact finish thickness and extended temperature range of the RJSAE538B08 represent performance enhancements.

Q: What is the significance of the contact finish thickness difference?

A: The RJSAE538B08 specifies 50.0µin (1.27µm) gold plating compared to 30.0µin (0.76µm) on the RJSNEJ38VA8. Increased plating thickness provides enhanced durability and contact resistance stability over extended operational life and repeated mating cycles.

Q: Does the extended operating temperature range of the RJSAE538B08 affect compatibility?

A: No. The RJSAE538B08 operating range of -55°C to 85°C encompasses the RJSNEJ38VA8 range of -40°C to 85°C. This extended capability does not introduce incompatibility; it provides additional operational margin for applications requiring lower temperature performance.

Q: Why is the RJSNEJ38VA8 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The RJSAE538B08, with active product status, represents the current equivalent offering from Amphenol ICC (Commercial Products) for this connector category.

Q: Are there packaging differences between these parts?

A: The RJSNEJ38VA8 packaging is not specified in the provided data. The RJSAE538B08 is supplied in Tray packaging. Packaging format does not affect electrical or mechanical compatibility; it addresses logistics and handling requirements.

Q: What compliance certifications apply to both parts?

A: Both the RJSNEJ38VA8 and RJSAE538B08 are RoHS Compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
