Key Parameters

Substitute Part Grouping Explanation

Substitute parts for RN122-2-02 are selected strictly based on the following allowed parameters from the product category: inductance at frequency, current rating, DCR, AC voltage rating, operating temperature range, number of lines, mounting type, mechanical dimensions, approval/certification status, and compliance with RoHS and REACH. All listed substitutes match these parameters within their specified values and are suitable for power line common mode choke applications with through-hole mounting and 2-line operation.

Parameter Comparison

Engineering Selection Recommendations

RN122-2-02 is obsolete and requires substitution to maintain compliance with design, certification, and inventory requirements. RN122-2-02-6M8 and B82724J2202N001 are both active, RoHS3 compliant, and hold ENEC, UR, and VDE approvals. RN122-2-02-6M8 offers the closest electrical and mechanical specifications, with slight differences in mechanical size and DCR. B82724J2202N001 also meets the electrical criteria, with variations in package orientation, dimension, and REACH status. Selection should be based on the required compliance and matching certification to the original part.

Frequently Asked Questions (FAQ)

Q1: Which key parameters must be matched when substituting common mode chokes in power line applications?
A1: Inductance at specified frequency, current rating, DCR, AC voltage rating, number of lines, operating temperature range, approval/certification, mounting type, and mechanical dimensions.

Q2: Is package orientation significant when selecting substitutes?
A2: Yes, package orientation and pin configuration (horizontal or vertical, 4 PC Pin) must align with the original footprint and PCB design requirements.

Q3: How does regulatory compliance affect substitution?
A3: Substitute parts must be RoHS and REACH compliant where specified and carry approvals such as UR, VDE, or ENEC if required by the application or region.

Q4: What if the substitute part's mechanical dimensions differ from the original?
A4: Any dimensional differences must be verified against the application requirements for fit and clearance in the assembly.

Q5: Are certificate approvals necessary when using substitute inductive components?
A5: Yes, equivalent certification (UR, VDE, ENEC) ensures continued regulatory and safety compliance for the replacement part.
