RN214-2-02 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The RN214-2-02 is a 4.2 mH common mode choke designed for two-line power line filtering applications. This through-hole mounted component is rated for 2A typical current with 102mOhm typical DC resistance and operates across -40°C to 125°C. The RN214-2-02 carries an obsolete product status, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The RN214-2-02-4M2 qualifies as a direct substitute based on the following critical parameters:

Electrical specifications match the primary requirements: 4.2 mH inductance at 10 kHz, 2-line configuration, 2A current rating, and comparable DC resistance (100mOhm vs. 102mOhm). Physical dimensions and mounting configuration are identical: 0.906" L x 0.610" W with 0.996" maximum height in vertical 4-pin through-hole package. Both components maintain the same series designation (RN) and filter type classification (Power Line).

The substitute part carries active product status with enhanced compliance certifications (ENEC, UR, VDE vs. UR, VDE) and improved RoHS classification (ROHS3 vs. RoHS Compliant). AC voltage rating increases from 250V to 300V, and moisture sensitivity is specified at MSL 1 (Unlimited).

Parameter Comparison

Engineering Selection Recommendations

The RN214-2-02-4M2 is the direct substitute for the obsolete RN214-2-02. Both components share identical electrical and mechanical specifications within acceptable engineering tolerances. The substitute part offers enhanced compliance status through active product availability and expanded certification coverage (addition of ENEC approval). RoHS classification is upgraded to ROHS3 standard.

Applications operating within the -40°C to 100°C temperature range benefit from the substitute part's full compliance profile. Systems requiring the extended -40°C to 125°C operating range of the original part must evaluate thermal performance requirements against the substitute's upper temperature limit of 100°C. The increased AC voltage rating (300V vs. 250V) of the substitute part provides additional design margin for power line filtering applications.

Frequently Asked Questions (FAQ)

Q: Can RN214-2-02-4M2 directly replace RN214-2-02 in existing designs?

A: Yes. Both parts maintain identical inductance (4.2 mH @ 10 kHz), current rating (2A), physical dimensions (0.906" L x 0.610" W x 0.996" H), and mounting configuration (vertical 4-pin through-hole). DC resistance values are equivalent within typical tolerances (100mOhm vs. 102mOhm).

Q: What are the key differences between these parts?

A: The substitute part (RN214-2-02-4M2) is active status versus obsolete, carries expanded certifications (ENEC addition), features improved RoHS classification (ROHS3), and provides higher AC voltage rating (300V vs. 250V). Operating temperature range differs: substitute is -40°C to 100°C versus original -40°C to 125°C.

Q: Are there packaging differences?

A: The original RN214-2-02 is supplied in standard packaging. The substitute RN214-2-02-4M2 is supplied in tube packaging. Both maintain identical component dimensions and through-hole pin configuration.

Q: Which part should be selected for new designs?

A: The RN214-2-02-4M2 is the appropriate selection for new designs. Active product status ensures long-term availability and supply chain continuity. Enhanced compliance certifications and ROHS3 classification align with current regulatory requirements.

Q: Are there temperature-related selection criteria?

A: Applications requiring operation above 100°C must evaluate the substitute part's thermal performance limits. The original part specification extends to 125°C. For applications within the -40°C to 100°C range, the substitute part is fully suitable.
