Substitute Part Grouping Explanation

Substitution of the ARJM11A1-007-AB-EW2 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector Type: RJ45
• Number of Ports: 1
• Applications: 10/100 Base-T, AutoMDIX
• Mounting Type: Through Hole
• Orientation: 90° Angle (Right)
• Termination: Solder
• Shielding: Shielded, EMI Finger
• Features: Board Lock
• Contact Finish: Gold
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

The substitute part A63-113-331P431 from Mercury United Electronics, Inc. meets all primary substitution criteria. Secondary parameters including height above board, LED color, number of cores per jack, and tab direction are consistent with the original specification, confirming functional equivalence for PCB integration and electrical performance in 10/100 Base-T network applications.

Parameter Comparison

Engineering Selection Recommendations

The A63-113-331P431 is the designated manufacturer-recommended substitute for the obsolete ARJM11A1-007-AB-EW2. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications.

The substitute part is currently in active production with 2470 units available in inventory, compared to the original part's obsolete status. The mechanical and electrical parameters are equivalent for PCB integration and 10/100 Base-T network functionality.

Design engineers should note the operating temperature range difference: the original part operates from -40°C to 85°C, while the substitute operates from 0°C to 70°C. For applications requiring extended low-temperature operation below 0°C, this parameter must be evaluated against system requirements. The contact finish thickness on the substitute (15.0µin) exceeds the original specification (6.00µin), providing enhanced durability and contact reliability.

Frequently Asked Questions (FAQ)

Q: Can A63-113-331P431 be used as a direct replacement for ARJM11A1-007-AB-EW2 in existing designs?

A: Yes. Both connectors share identical connector type (RJ45), port configuration (1 port), application support (10/100 Base-T, AutoMDIX), mounting method (Through Hole), orientation (90° Right), termination (Solder), shielding (Shielded, EMI Finger), and board lock features. PCB footprints and electrical performance are compatible.

Q: What are the key differences between these parts?

A: The primary differences are product status (original is obsolete; substitute is active), operating temperature range (original: -40°C to 85°C; substitute: 0°C to 70°C), and contact finish thickness (original: 6.00µin; substitute: 15.0µin). Both maintain ROHS3 compliance and identical regulatory classifications.

Q: Is the operating temperature range difference significant for substitution?

A: The operating temperature range must be evaluated against your specific application requirements. If your system operates below 0°C, the substitute's minimum operating temperature of 0°C may not be suitable. For applications within the 0°C to 70°C range, the substitute is fully qualified.

Q: What is the packaging difference?

A: The original part packaging is not specified in available documentation. The substitute is supplied in Tray packaging, which is standard for production and inventory management.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both share the same HTSUS classification (8536.69.4040).

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL Rating 1 (Unlimited), indicating unlimited shelf life without moisture sensitivity concerns. This simplifies storage, handling, and inventory management for both the original and substitute parts.
