Parameter Comparison

Engineering Selection Recommendations

The 2250020-1 (TRP Connector B.V.) is a suitable substitute for the obsolete ARJM11C7-559-AD-EW4 based on the following engineering criteria:

Compliance & Regulatory: Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for current manufacturing standards.

Functional Compatibility: Both connectors support identical 10/100/1000 Base-T Ethernet applications with AutoMDIX functionality and 8-core jack configuration. Shielding specifications (Shielded, EMI Finger) are equivalent, maintaining electromagnetic interference protection.

Mechanical Fit: PCB mounting dimensions are compatible within standard tolerance. The height difference of 0.004" (0.10mm) is within typical PCB layout margins and does not require design modification.

Product Status Advantage: The 2250020-1 is classified as Active, ensuring long-term availability and supply chain stability compared to the Obsolete status of the main part.

Operating Temperature Consideration: The substitute part operates within 0°C ~ 70°C, which is narrower than the main part's -40°C ~ 85°C range. Applications requiring extended temperature operation below 0°C or above 70°C must evaluate this limitation.

Frequently Asked Questions (FAQ)

Q: Can the 2250020-1 be used as a direct drop-in replacement for the ARJM11C7-559-AD-EW4?

A: Yes, for applications operating within 0°C ~ 70°C. Both connectors share identical RJ45 configuration, 90° right-angle orientation, through-hole solder termination, and 10/100/1000 Base-T AutoMDIX functionality. The 0.004" height difference does not require PCB redesign.

Q: What is the difference in LED indicator colors between these parts?

A: The ARJM11C7-559-AD-EW4 features Green - Orange LEDs, while the 2250020-1 features Green - Yellow LEDs. Both indicate link status and activity; the color difference does not affect electrical function but may impact visual identification in applications where specific LED colors are required.

Q: Are there operating temperature restrictions when substituting?

A: Yes. The substitute part 2250020-1 operates within 0°C ~ 70°C, compared to the main part's -40°C ~ 85°C range. Applications requiring operation below 0°C or above 70°C must use the original part or identify alternative substitutes with extended temperature ratings.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the ARJM11C7-559-AD-EW4 and 2250020-1 are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory standards.

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

A: The 2250020-1 has a thicker gold contact finish (50.0µin vs. 30.0µin). This provides enhanced durability and wear resistance, particularly beneficial for high-cycle mating applications. The thicker finish does not negatively impact electrical performance.

Q: Is the MagJack® series designation important for compatibility?

A: The MagJack® designation indicates the product series from TRP Connector B.V. It does not affect electrical or mechanical compatibility. The functional specifications (RJ45, 1 port, 10/100/1000 Base-T, AutoMDIX) determine substitution suitability.
