Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSNEJ38HA8 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

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

The RJSAE538H08 meets all mandatory matching parameters and qualifies as a direct substitute. The substitute part is manufactured by the same supplier (Amphenol ICC) and maintains identical electrical and mechanical interface specifications. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The RJSAE538H08 is a qualified substitute for the obsolete RJSNEJ38HA8. Both parts are RoHS compliant and carry identical Moisture Sensitivity Level 1 ratings, ensuring compliance with environmental and regulatory requirements.

The substitute part demonstrates enhanced specifications in two areas: contact finish thickness (50.0µin versus 30.0µin) and operating temperature range (-55°C to 85°C versus -40°C to 85°C). These enhancements do not create incompatibility; they represent improved performance margins suitable for applications requiring extended environmental tolerance.

The RJSAE538H08 maintains active product status with Amphenol ICC, providing assured supply chain continuity and manufacturing support. Selection of the substitute part eliminates obsolescence risk while preserving full electrical and mechanical compatibility with existing PCB designs and mating components.

Frequently Asked Questions (FAQ)

Q: Can the RJSAE538H08 be used as a direct replacement for the RJSNEJ38HA8 without PCB redesign?

A: Yes. Both connectors share identical mounting type (through hole), orientation (90° right angle), termination method (solder), and footprint-critical parameters. No PCB layout modifications are required.

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

A: The RJSAE538H08 provides 50.0µin gold plating compared to 30.0µin on the RJSNEJ38HA8. This represents enhanced contact durability and corrosion resistance. The thicker plating does not affect electrical performance or mechanical fit.

Q: Why does the substitute part have a wider operating temperature range?

A: The RJSAE538H08 operates from -55°C to 85°C, extending the lower temperature limit by 15°C compared to the RJSNEJ38HA8 (-40°C to 85°C). This expanded range provides additional environmental margin for applications in extreme conditions. Both parts function identically within the original part's temperature specification.

Q: Are both parts RoHS compliant?

A: Yes. Both the RJSNEJ38HA8 and RJSAE538H08 are RoHS compliant with Moisture Sensitivity Level 1 (unlimited shelf life). No compliance issues arise from substitution.

Q: What is the inventory status of the substitute part?

A: The RJSAE538H08 is actively manufactured by Amphenol ICC with 960 pieces in current stock. The original RJSNEJ38HA8 is obsolete with 727 pieces remaining in inventory.

Q: Are there any electrical performance differences between the two connectors?

A: No. Both connectors feature identical electrical specifications: 8p8c (RJ45, Ethernet) configuration, phosphor bronze contacts with gold finish, and shielded design with EMI finger. Electrical performance is equivalent.
