Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11D7-502-AB-ER4-T is determined by strict equivalence across the following critical parameters:

• Connector Type: RJ45
• Number of Ports: 1
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Height Above Board: 0.543" (13.80mm)
• Applications: 10/100/1000 Base-T, AutoMDIX
• Shielding: Shielded
• Number of Cores per Jack: 8
• Contact Finish: Gold
• Operating Temperature Range: -40°C ~ 85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The ARJM11D7-502-AB-ER2-T meets all substitution criteria as a direct equivalent within the ARJM11 series. The primary difference is the contact finish thickness specification, which does not affect functional compatibility or electrical performance in this application category.

Parameter Comparison

Engineering Selection Recommendations

The ARJM11D7-502-AB-ER2-T is a direct functional equivalent to the obsolete ARJM11D7-502-AB-ER4-T. Both components are ROHS3 compliant, REACH unaffected, and classified under the same HTSUS code. The substitute part maintains identical electrical and mechanical specifications across all critical parameters including connector type, port configuration, mounting method, orientation, board height, application support, shielding, core count, contact material, and operating temperature range.

The ARJM11D7-502-AB-ER2-T carries active product status, ensuring ongoing availability and manufacturer support. The contact finish thickness difference (30.0µin versus 6.00µin) does not impact functional compatibility or performance in 10/100/1000 Base-T Ethernet applications.

Frequently Asked Questions (FAQ)

Q: Can the ARJM11D7-502-AB-ER2-T be used as a direct replacement for the ARJM11D7-502-AB-ER4-T?

A: Yes. Both connectors are functionally equivalent across all critical parameters: RJ45 type, single port, through-hole mounting, 90° right-angle orientation, 13.80mm board height, 10/100/1000 Base-T AutoMDIX support, shielded construction, 8-core configuration, gold contact finish, and identical operating temperature range. The parts are electrically and mechanically interchangeable.

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

A: Contact finish thickness (30.0µin for ER4 versus 6.00µin for ER2) is a manufacturing specification that does not affect electrical performance, signal integrity, or mechanical compatibility in this connector category. Both thicknesses provide adequate gold plating for reliable contact performance in Ethernet applications.

Q: Why is the ARJM11D7-502-AB-ER4-T listed as obsolete?

A: Product obsolescence is determined by the manufacturer and typically reflects end-of-life decisions. The ARJM11D7-502-AB-ER2-T maintains active status, providing a current production alternative with identical functional specifications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical compliance certifications: ROHS3 compliant, REACH unaffected, EAR99 classification, and the same HTSUS code (8536.69.4040). Moisture sensitivity level is identical at MSL 1 (unlimited).

Q: Will PCB layout or footprint require modification when switching to the substitute part?

A: No. The ARJM11D7-502-AB-ER2-T maintains identical mounting specifications: through-hole termination, 90° right-angle orientation, and 0.543" (13.80mm) height above board. Existing PCB designs require no modification.
