Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11D7-502-AB-EW4 is determined by strict equivalence across the following critical parameters:

• Connector type and port configuration (RJ45, 1-port)
• Mounting method and orientation (through-hole, 90° right-angle)
• Electrical specifications (10/100/1000 Base-T, AutoMDIX, 8-core)
• Physical dimensions (height above board: 0.543" / 13.80mm)
• Shielding and board lock features
• Operating temperature range (-40°C ~ 85°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The ARJM11D7-502-AB-EW2 qualifies as a direct substitute based on identical alignment across all critical parameters. The primary distinction is packaging format (tray vs. original packaging) and contact finish thickness specification, neither of which affects functional compatibility or electrical performance in the target application.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11D7-502-AB-EW2 is the qualified substitute for the obsolete ARJM11D7-502-AB-EW4. Selection is supported by:

• Identical electrical and mechanical specifications across all functional parameters
• Active product status of the substitute part, ensuring long-term availability and supply chain continuity
• Equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected)
• Maintained operating temperature range and environmental specifications
• Identical connector geometry and PCB footprint compatibility

The transition from the obsolete ARJM11D7-502-AB-EW4 to the ARJM11D7-502-AB-EW2 requires no design modifications and presents no functional or compatibility risks.

Frequently Asked Questions (FAQ)

Q: Can the ARJM11D7-502-AB-EW2 be used as a direct replacement for the ARJM11D7-502-AB-EW4 without PCB redesign?

A: Yes. Both parts share identical connector geometry, pinout, mounting footprint, and electrical specifications. No PCB layout modifications are required.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (obsolete vs. active) and packaging format (original vs. tray). The ARJM11D7-502-AB-EW2 is the active production variant. Contact finish thickness specifications differ slightly but do not affect electrical performance or reliability.

Q: Are the LED indicators identical between both parts?

A: Yes. Both parts feature green-yellow dual LED indicators with identical color and function.

Q: Does the tray packaging of the ARJM11D7-502-AB-EW2 affect component performance?

A: No. Packaging format does not influence electrical or mechanical performance. Tray packaging is standard for active production parts and provides equivalent protection during storage and handling.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the ARJM11D7-502-AB-EW4 and ARJM11D7-502-AB-EW2 are ROHS3 compliant and REACH unaffected, meeting current regulatory standards.

Q: What is the operating temperature range for both connectors?

A: Both parts operate across the identical temperature range of -40°C to 85°C, suitable for industrial and commercial Ethernet applications.
