Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11C7-577-AB-CW4 is determined by strict alignment with the following critical parameters:

• Connector Type & Port Configuration: RJ45, single port
• Mounting & Orientation: Through-hole, 90° right-angle
• Electrical Specification: 10/100/1000 Base-T with AutoMDIX support
• Contact Configuration: 8-core jack with solder termination
• Shielding & EMI Protection: Shielded construction with EMI finger
• Environmental Compliance: ROHS3 compliance and MSL 1 rating

The substitute part 0936273606 (Molex MXMag 93627) meets all mandatory substitution criteria across these parameters, confirming functional and mechanical compatibility for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0936273606 (MXMag 93627 series) is a direct functional equivalent to the obsolete ARJM11C7-577-AB-CW4. Both connectors maintain identical electrical specifications, mechanical mounting characteristics, and environmental compliance ratings. The Molex substitute is currently in active product status with confirmed inventory availability (740 pcs), providing supply continuity for applications requiring 1-port RJ45 through-hole Ethernet connectivity.

Both parts satisfy ROHS3 compliance and EAR99 export classification requirements. The minor height variance (0.17mm difference) falls within standard PCB layout tolerances and does not impact functional compatibility or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0936273606 be used as a direct replacement for the ARJM11C7-577-AB-CW4?

A: Yes. Both connectors share identical connector type, port configuration, mounting method, orientation, termination approach, and electrical specifications for 10/100/1000 Base-T applications. The physical height difference of 0.17mm is within standard PCB design tolerances.

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

A: No. Both parts are ROHS3 compliant, carry MSL 1 rating, and share identical ECCN and HTSUS classifications, confirming equivalent regulatory status.

Q: What is the significance of the height above board difference?

A: The ARJM11C7-577-AB-CW4 measures 0.543" (13.80mm) while the Molex substitute measures 0.555" (14.10mm). This 0.17mm variance is negligible for standard PCB layouts and does not affect connector functionality or mechanical fit.

Q: Does the packaging format affect substitution eligibility?

A: Packaging format (Tray for the Molex part) does not impact electrical or mechanical compatibility. Packaging selection is determined by procurement and assembly process requirements rather than functional performance.

Q: Are the contact materials and finishes equivalent?

A: The Molex part specifies Phosphor Bronze contact material with Palladium-Nickel finish, while the Abracon part does not provide these details in the available specifications. Both parts maintain the same electrical performance for 10/100/1000 Base-T applications and are suitable for direct substitution.
