RN214-4-02 Equivalent & Substitute Parts

Part Overview

The RN214-4-02 is a common mode choke (CMC) designed for power line filtering applications. This through-hole mounted component provides 1.5 mH inductance at 1 kHz with a 4A typical current rating and 35 mOhm DC resistance. The part is rated for 250V AC operation across a temperature range of -40°C to 125°C and carries approvals from UR and VDE standards bodies.

The RN214-4-02 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN214-4-02 is determined by the following critical parameters:

Electrical Compatibility:

• Inductance value: 1.5 mH (measurement frequency may vary)
• Current rating: 4A minimum
• DC resistance: Must not exceed 35 mOhm significantly
• Voltage rating: AC rating must meet or exceed 250V

Mechanical Compatibility:

• Mounting type: Through Hole
• Package configuration: Vertical, 4 PC Pin
• Physical dimensions: 0.906" L x 0.610" W (23.00mm x 15.50mm)
• Height: 0.996" (25.30mm)

Regulatory & Compliance:

• RoHS compliance required
• Approval agencies: UR and/or VDE certification

The substitute part RN214-4-02-1M5 meets these criteria while offering improved product status and expanded certifications.

Parameter Comparison

Engineering Selection Recommendations

The RN214-4-02-1M5 serves as a direct substitute for the obsolete RN214-4-02. Both components share identical mechanical form factors, mounting configurations, and core electrical specifications (1.5 mH inductance, 4A current rating, 2-line configuration).

The substitute part offers the following advantages:

Product Availability: The RN214-4-02-1M5 maintains active product status with significantly higher inventory availability (19,062 pcs vs. 1,094 pcs), ensuring reliable supply chain access.

Enhanced Compliance: The substitute carries ENEC certification in addition to UR and VDE approvals, providing broader regulatory coverage. ROHS3 compliance supersedes the RoHS Compliant status of the original part.

Electrical Performance: DC resistance is reduced to 34 mOhm (from 35 mOhm), and AC voltage rating is increased to 300V (from 250V), providing improved electrical margins.

Temperature Consideration: The substitute operates across -40°C to 100°C, which is narrower than the original -40°C to 125°C range. Applications requiring operation above 100°C must retain the original part or identify alternative solutions.

Inductance Measurement Frequency: The substitute specifies inductance at 10 kHz rather than 1 kHz. Both measurements represent the same nominal 1.5 mH value; the frequency difference reflects standard measurement methodology variations and does not affect functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the RN214-4-02-1M5 replace the RN214-4-02 in existing designs?

A: Yes, for applications operating within -40°C to 100°C. The substitute maintains identical mechanical dimensions, pin configuration, and core electrical specifications. Applications requiring operation above 100°C require design review.

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

A: Both measurements represent the same 1.5 mH nominal inductance value. The measurement frequency reflects the test standard used by the manufacturer. This difference does not affect component selection or circuit performance.

Q: Are there inventory or lead time advantages to using the substitute part?

A: Yes. The RN214-4-02-1M5 is an active product with 19,062 units in stock, compared to 1,094 units for the obsolete RN214-4-02. This significantly improves supply chain reliability and reduces procurement lead times.

Q: Does the increased AC voltage rating (300V vs. 250V) affect circuit design?

A: No. The higher voltage rating of the substitute provides additional safety margin and is fully compatible with designs rated for 250V operation. This represents an improvement in component robustness.

Q: What packaging differences exist between these parts?

A: The main part is supplied without specified packaging; the substitute is supplied in Tube packaging. Both maintain identical physical dimensions and pin configurations suitable for through-hole assembly.

Q: Are both parts RoHS compliant?

A: Yes. The original part is RoHS Compliant; the substitute is ROHS3 Compliant, which represents an updated compliance standard. Both are suitable for RoHS-regulated applications.
