RN214-0.3-02 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The RN214-0.3-02 is a 47 mH 2-line common mode choke designed for power line filtering applications in through-hole mounting configurations. This component is classified as obsolete, necessitating identification of active equivalent parts that maintain functional compatibility within the specified electrical and mechanical parameters. Substitute parts must preserve the core filtering characteristics while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Inductance Value & Frequency: 47 mH nominal inductance measured at specified frequency
• Number of Lines: 2-line configuration for common mode filtering
• Current Rating: 300mA maximum continuous current capacity
• Mounting Type: Through-hole vertical orientation with 4-pin configuration
• Physical Dimensions: Compatible footprint within specified length, width, and height tolerances
• Voltage Rating: AC voltage withstand capability
• Operating Temperature Range: Functional performance across specified thermal limits
• Regulatory Compliance: UR, VDE, or equivalent certifications

Parts meeting these criteria are classified as direct substitutes. Variations in DC resistance, frequency measurement point, or compliance certifications do not disqualify substitution when core electrical and mechanical parameters align.

Engineering Selection Recommendations

RN214-0.3-02-47M (Schaffner EMC Inc., Active Status)

This part is the direct manufacturer successor to the obsolete RN214-0.3-02. It maintains identical physical dimensions and mounting configuration. The inductance measurement frequency differs (10 kHz vs. 1 kHz), and DC resistance is marginally lower (1.7Ohm vs. 1.75Ohm). AC voltage rating is elevated to 300V. Operating temperature range is reduced to -40°C ~ 100°C. Compliance certifications include ENEC in addition to UR and VDE. RoHS3 compliance is confirmed. This part is recommended as the primary replacement for direct substitution.

B82722J2301N001 (EPCOS - TDK Electronics, Active Status)

This part provides functional equivalence with minor dimensional variations. Physical dimensions are slightly larger (0.917" L x 0.634" W vs. 0.906" L x 0.610" W; height 1.000" vs. 0.996"). DC resistance is higher at 2.5Ohm compared to 1.75Ohm. AC voltage rating matches the original at 250V. Operating temperature range matches the original at -40°C ~ 125°C. Compliance certifications include ENEC, UR, and VDE. REACH status is affected. This part is suitable for applications where dimensional tolerance and DC resistance variation are acceptable within circuit design parameters.

Frequently Asked Questions (FAQ)

Q: Can RN214-0.3-02-47M be used as a direct replacement for RN214-0.3-02?

A: Yes. Both parts share identical physical dimensions, mounting configuration, and core electrical specifications (47 mH inductance, 300mA current rating, 2-line configuration). The RN214-0.3-02-47M is the active production equivalent and is recommended as the primary replacement.

Q: What is the significance of the inductance measurement frequency difference (1 kHz vs. 10 kHz)?

A: Inductance values are frequency-dependent. The RN214-0.3-02 specifies 47 mH @ 1 kHz, while RN214-0.3-02-47M specifies 47 mH @ 10 kHz. Both maintain the 47 mH nominal value at their respective measurement frequencies. Application circuit design must account for the frequency at which inductance is specified.

Q: Is B82722J2301N001 compatible with the original RN214-0.3-02?

A: B82722J2301N001 is functionally equivalent for common mode choke applications with the same inductance, current rating, and line configuration. Physical dimensions are marginally larger, and DC resistance is higher (2.5Ohm vs. 1.75Ohm). PCB layout and thermal design must accommodate these variations. Verify circuit tolerance for increased DC resistance before selection.

Q: What are the packaging differences among these parts?

A: RN214-0.3-02 packaging is unspecified. RN214-0.3-02-47M is supplied in tube packaging. B82722J2301N001 is supplied in tray packaging. Packaging affects handling, storage, and automated assembly compatibility but does not impact electrical or mechanical performance.

Q: Are all three parts RoHS compliant?

A: RN214-0.3-02 is RoHS Compliant. RN214-0.3-02-47M is ROHS3 Compliant. B82722J2301N001 is ROHS3 Compliant. All parts meet RoHS requirements; ROHS3 represents the current compliance standard.

Q: What is the impact of the operating temperature range reduction in RN214-0.3-02-47M?

A: RN214-0.3-02 operates from -40°C ~ 125°C. RN214-0.3-02-47M operates from -40°C ~ 100°C. Applications requiring operation above 100°C must use the original part or B82722J2301N001, which maintains the -40°C ~ 125°C range.
