Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARJM11A3-504-KB-EW2 is determined by the following critical parameters:

• Connector Type & Port Configuration: RJ45, single port
• Mounting & Orientation: Through hole, 90° right-angle
• Electrical Performance: 10/100/1000 Base-T with AutoMDIX support
• Physical Interface: 8-core jack with solder termination
• Environmental Protection: Shielded construction with EMI finger
• Compliance: ROHS3 and REACH requirements

The substitute part 2250069-1 (TRP Connector B.V., MagJack® series) meets all critical substitution criteria. Both components share identical connector type, port count, mounting method, orientation, termination style, core count, shielding configuration, and compliance certifications. Variations in height above board (0.535" vs 0.541"), LED color options, tab direction, and operating temperature range do not preclude functional equivalence in applications designed for the original component.

Parameter Comparison

Engineering Selection Recommendations

The 2250069-1 (TRP Connector B.V.) is the designated equivalent for the obsolete ARJM11A3-504-KB-EW2. Selection is supported by:

• Product Status: The substitute is active, ensuring long-term availability and supply chain continuity.
• Functional Equivalence: All critical electrical and mechanical parameters align with the original component.
• Compliance Alignment: Both components maintain ROHS3 and REACH compliance, with identical ECCN and HTSUS classifications.
• Inventory Availability: The substitute part is currently in stock (896 pcs).

The operating temperature range of the substitute (0°C ~ 70°C) is narrower than the original (-40°C ~ 85°C). Applications requiring operation below 0°C or above 70°C must evaluate this limitation against specific system requirements. The height differential of 0.006" (0.16mm) is within typical PCB layout tolerances for through-hole connectors and does not impact functional compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the 2250069-1 be used as a direct replacement for the ARJM11A3-504-KB-EW2 in existing designs?

A: Yes. Both connectors share identical connector type, port configuration, mounting method, orientation, termination style, core count, and shielding. PCB layouts designed for the original component will accommodate the substitute without modification.

Q: What is the significance of the height difference (0.535" vs 0.541")?

A: The 0.006" (0.16mm) difference is negligible for standard PCB applications. This variation falls within normal manufacturing tolerances for through-hole connectors and does not affect electrical performance or mechanical fit in typical designs.

Q: Are there operating temperature restrictions when using the substitute?

A: The 2250069-1 operates within 0°C ~ 70°C, compared to the original -40°C ~ 85°C range. Applications requiring operation outside this narrower range must evaluate alternative components or confirm that the substitute's temperature limits are acceptable for the intended environment.

Q: Do both connectors support the same network standards?

A: Yes. Both components are rated for 10/100/1000 Base-T with AutoMDIX functionality, providing identical network performance capabilities.

Q: Are there differences in LED indicator specifications?

A: The original features Green and Orange-Yellow LEDs, while the substitute offers Green and Yellow-Green or Yellow options. LED color differences do not affect electrical functionality but may impact visual indication schemes in applications where specific LED colors are required.

Q: What is the tab direction difference, and does it matter?

A: The original has tab direction Down, while the substitute has tab direction Up. This difference relates to mechanical retention features and does not affect electrical compatibility. PCB design should accommodate the substitute's tab orientation.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the ARJM11A3-504-KB-EW2 and 2250069-1 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.
