RJSNEJ38408 Equivalent & Substitute Parts

Part Overview

The RJSNEJ38408 is a modular jack connector manufactured by Amphenol ICC (Commercial Products) in the RJSNE series. This component is an 8-position 8-contact (8p8c) RJ45 Ethernet jack with 90° right-angle orientation, shielded design with EMI finger, and through-hole solder termination. The connector features board lock functionality, green-yellow LED indicators, and phosphor bronze contacts with gold finish.

The RJSNEJ38408 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJSNEJ38408 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 8p8c (RJ45, Ethernet)
• Orientation: 90° Angle (Right)
• Mounting Type: Through Hole
• Termination: Solder
• Shielding: Shielded, EMI Finger
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Housing Material: Thermoplastic
• RoHS Compliance: Yes

Allowable Variation Parameters:

• Operating Temperature Range: Substitute may extend the range
• Contact Finish Thickness: Substitute may differ
• Product Status: Substitute may be Active (preferred for new supply)
• Packaging: Substitute may differ
• LED Color: Substitute maintains Green - Yellow
• Tab Direction: Substitute maintains Up and Down

The RJSAE538408 meets all mandatory matching parameters and represents a direct functional equivalent with enhanced specifications in operating temperature range and contact finish thickness.

Engineering Selection Recommendations

RJSNEJ38408 (Original Part): The RJSNEJ38408 is classified as obsolete. While inventory is currently available (958 pieces), the obsolete status indicates that manufacturer support and long-term availability cannot be guaranteed. This part is suitable only for immediate replacement or repair of existing systems where no design modification is possible.

RJSAE538408 (Substitute Part): The RJSAE538408 is the recommended substitute for new designs and ongoing production. This part carries an active product status, ensuring continued manufacturer support and supply chain reliability. The RJSAE538408 provides identical functional performance across all critical parameters while offering enhanced specifications:

• Extended operating temperature range (-55°C to 85°C versus -40°C to 85°C)
• Increased contact finish thickness (50.0µin versus 30.0µin), providing improved durability and contact reliability

Both parts are RoHS compliant, carry identical ECCN and HTSUS classifications, and maintain the same moisture sensitivity level. The RJSAE538408 is supplied in tray packaging, which is standard for production environments.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538408 be used as a direct replacement for the RJSNEJ38408 in existing designs?

A: Yes. The RJSAE538408 is functionally equivalent across all critical parameters: connector type, contact count, orientation, mounting method, termination type, shielding, contact material, and finish. The substitute maintains identical mechanical and electrical compatibility with the original part.

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

A: The RJSAE538408 features a contact finish thickness of 50.0µin (1.27µm) compared to 30.0µin (0.76µm) on the RJSNEJ38408. The increased thickness on the substitute part provides enhanced durability and extended contact life under repeated mating cycles, while maintaining full electrical compatibility.

Q: Why is the RJSNEJ38408 listed as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this part. While existing inventory may be available, long-term supply cannot be assured. The RJSAE538408 active status ensures continued availability and manufacturer support.

Q: Does the extended operating temperature range of the RJSAE538408 affect compatibility?

A: No. The RJSAE538408 operating range of -55°C to 85°C encompasses the original part's range of -40°C to 85°C. The extended lower temperature limit represents an enhancement that does not compromise compatibility with designs specified for the original part.

Q: Are there any packaging considerations when switching from RJSNEJ38408 to RJSAE538408?

A: The RJSAE538408 is supplied in tray packaging, which is standard for production environments. The original part packaging is not specified in the available data. Verify that tray packaging is compatible with your assembly and handling processes.

Q: Do both parts carry the same regulatory certifications?

A: Yes. Both the RJSNEJ38408 and RJSAE538408 are RoHS compliant, carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, and maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: Can the RJSAE538408 be used in applications requiring the full -40°C to 85°C temperature range?

A: Yes. The RJSAE538408 operating range of -55°C to 85°C fully supports applications specified for -40°C to 85°C operation.
