RN212-1.5-02 Equivalent & Substitute Parts

Part Overview

The RN212-1.5-02 is a 3.3 mH common mode choke (CMC) designed for two-line power line filtering applications. This through-hole component is rated for 1.5A typical current with a DC resistance of 135 mOhm and operates across a temperature range of -40°C to 125°C. The part carries obsolete product status, making identification of suitable substitutes essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN212-1.5-02 is determined by the following critical parameters:

• Inductance Value: 3.3 mH nominal inductance
• Current Rating: 1.5A minimum capacity
• Number of Lines: 2-line configuration for common mode filtering
• Mounting Type: Through-hole vertical orientation with 4-pin package
• Physical Dimensions: 18.00 mm L x 12.50 mm W x 20.30 mm H maximum
• Electrical Ratings: AC voltage and temperature operating range compatibility

The RN212-1.5-02-3M3 qualifies as a direct substitute based on matching inductance value, current rating, line configuration, mounting type, and physical footprint. Variations in measurement frequency (1 kHz vs. 10 kHz), DC resistance (135 mOhm vs. 102 mOhm), and AC voltage rating (250V vs. 300V) reflect design improvements in the active successor model.

Parameter Comparison

Engineering Selection Recommendations

The RN212-1.5-02-3M3 is the direct substitute for the obsolete RN212-1.5-02. Both components share identical mechanical footprints and electrical core specifications (3.3 mH inductance, 1.5A current rating, 2-line configuration). The substitute maintains all required certifications (UR, VDE) with additional ENEC approval. The active product status of the RN212-1.5-02-3M3 ensures ongoing availability and supply chain continuity.

For applications operating within the -40°C to 100°C temperature range, the RN212-1.5-02-3M3 provides equivalent or superior performance. The reduced DC resistance (102 mOhm vs. 135 mOhm) and increased AC voltage rating (300V vs. 250V) represent design enhancements. Applications requiring the full -40°C to 125°C operating range of the original part require evaluation of the substitute's 100°C maximum temperature limit.

Frequently Asked Questions (FAQ)

Q: Can the RN212-1.5-02-3M3 be used as a direct replacement for the RN212-1.5-02?

A: Yes. Both components have identical physical dimensions, mounting configuration, and core electrical specifications (3.3 mH inductance, 1.5A current rating, 2-line common mode choke). Pin-to-pin compatibility is confirmed.

Q: What are the differences between these two parts?

A: The primary differences are product status (obsolete vs. active), measurement frequency (1 kHz vs. 10 kHz), DC resistance (135 mOhm vs. 102 mOhm), AC voltage rating (250V vs. 300V), and certifications (UR/VDE vs. ENEC/UR/VDE). The substitute offers improved electrical performance and broader regulatory approval.

Q: Are there temperature range considerations for substitution?

A: The RN212-1.5-02 operates to 125°C maximum, while the RN212-1.5-02-3M3 operates to 100°C maximum. Applications requiring operation above 100°C must evaluate this limitation against system requirements.

Q: What packaging is available for the RN212-1.5-02-3M3?

A: The substitute is supplied in tube packaging, compared to the original part's standard packaging. Both maintain the same through-hole vertical, 4-pin configuration.

Q: Are both parts RoHS compliant?

A: Yes. The RN212-1.5-02 is RoHS Compliant. The RN212-1.5-02-3M3 is ROHS3 Compliant, representing compliance with the current RoHS 3 directive.
