The substitute part A63-113-331P431 from Mercury United Electronics, Inc. meets all mandatory parameters and is classified as an active product with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The A63-113-331P431 is a qualified substitute for the ARJM11A1-007-AD-EW2 based on functional and compliance alignment. Both parts are ROHS3 compliant and carry identical Moisture Sensitivity Level ratings. The substitute part is currently in active production status with 2470 units in stock, compared to the obsolete main part with 1127 units remaining.

Key considerations for selection:

Operating Temperature Range: The substitute part operates within 0°C to 70°C, which is narrower than the main part's -40°C to 85°C range. Applications requiring operation below 0°C or above 70°C must retain the original part or identify alternative solutions.

Contact Finish Thickness: The substitute provides 15.0µin finish thickness compared to 6.00µin on the original part, offering enhanced durability and contact reliability.

LED Indicator Color: The substitute uses Green-Yellow LED indicators instead of Green-Orange. This difference is functional but may require visual identification updates in system documentation or operator training materials.

Packaging: The substitute is supplied in Tray packaging, whereas original packaging information is not specified for the main part.

Frequently Asked Questions (FAQ)

Q: Can A63-113-331P431 be used as a direct replacement in all applications?

A: The A63-113-331P431 is functionally equivalent for 10/100 Base-T Ethernet applications with AutoMDIX support. However, applications requiring operation below 0°C or above 70°C must use the original ARJM11A1-007-AD-EW2 or identify alternative parts with extended temperature ranges.

Q: What is the significance of the different LED colors?

A: The LED color difference (Green-Orange vs. Green-Yellow) does not affect electrical functionality. Both indicate link status and activity. The color change is a cosmetic variation between manufacturers and may require updates to system documentation or operator training if visual identification is critical.

Q: Are both parts pin-compatible?

A: Both parts are RJ45 connectors with 4 cores per jack, solder termination, and identical port configuration. PCB footprint compatibility is supported by matching mounting type, orientation, and height above board specifications within 0.004" tolerance.

Q: What is the difference in contact finish thickness?

A: The substitute part features 15.0µin gold plating compared to 6.00µin on the original. Thicker plating generally provides improved contact durability and resistance to wear over extended mating cycles.

Q: Is the substitute part suitable for new designs?

A: Yes. The A63-113-331P431 is an active product with current manufacturing support and inventory availability, making it suitable for new designs, legacy system updates, and ongoing production requirements.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 export classification. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.
