RN214-1.5-02 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The RN214-1.5-02 is a 6.8 mH common mode choke designed for two-line power line filtering applications. Manufactured by Schaffner EMC Inc., this through-hole component operates at 1.5A typical current with a 130 mOhm DC resistance. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for continued system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Inductance value: 6.8 mH @ 10 kHz (exact match required)
• Number of lines: 2 (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Vertical, 4 PC Pin (exact match required)
• Filter type: Power Line (exact match required)

Allowable variations within substitution:

• Current rating: May be equal to or greater than 1.5A
• DC resistance: May be lower than or equal to 130 mOhm
• AC voltage rating: May be equal to or greater than 250V
• Operating temperature range: May be equal to or encompass -40°C ~ 125°C
• Physical dimensions: Minor variations acceptable if footprint compatibility is maintained

Two substitute parts meet these criteria:

RN214-1.5-02-6M8 (Schaffner EMC Inc.) — Direct manufacturer variant with improved specifications and active product status.

B82732R2172B030 (EPCOS - TDK Electronics) — Cross-manufacturer equivalent with compatible electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

RN214-1.5-02-6M8 is the preferred substitute for direct replacement applications. This part is a Schaffner EMC Inc. variant maintaining identical mechanical footprint and inductance specifications. It offers improved DC resistance (123 mOhm vs. 130 mOhm), higher AC voltage rating (300V vs. 250V), and active product status with ROHS3 compliance and expanded approval certifications (ENEC, UR, VDE). The operating temperature range is -40°C ~ 100°C, which is narrower than the original part; applications requiring operation above 100°C require thermal analysis.

B82732R2172B030 is a cross-manufacturer alternative from EPCOS - TDK Electronics suitable for applications where component sourcing flexibility is required. This part maintains identical inductance, line count, and mounting configuration. Physical dimensions show minor variations (0.945" L x 0.650" W vs. 0.906" L x 0.610" W; height 0.925" vs. 0.996"), requiring PCB layout verification. DC resistance is higher at 190 mOhm, and current rating is elevated to 1.7A. AC voltage rating matches the original at 250V, and operating temperature range matches at -40°C ~ 125°C. ROHS3 compliance and multi-agency approvals (ENEC, UR, VDE) are provided.

Selection between these substitutes depends on thermal requirements, PCB layout constraints, and sourcing strategy. For designs operating above 100°C, B82732R2172B030 is required. For designs with tight PCB space, RN214-1.5-02-6M8 maintains original dimensions.

Frequently Asked Questions (FAQ)

Q: Can RN214-1.5-02-6M8 be used as a direct drop-in replacement for RN214-1.5-02?

A: Yes. Both parts share identical inductance (6.8 mH @ 10 kHz), current rating (1.5A), number of lines (2), mounting type (through hole), and physical dimensions (0.906" L x 0.610" W, height 0.996"). The primary difference is improved DC resistance and higher AC voltage rating in the active variant. Packaging differs (tube vs. tray), which affects procurement but not circuit performance.

Q: What are the dimensional constraints when considering B82732R2172B030?

A: B82732R2172B030 has slightly larger length (0.945" vs. 0.906") and width (0.650" vs. 0.610"), but lower height (0.925" vs. 0.996"). PCB layout must accommodate the increased footprint dimensions. Pin configuration remains vertical, 4 PC Pin, maintaining electrical compatibility.

Q: Is B82732R2172B030 suitable for applications requiring operation above 100°C?

A: Yes. B82732R2172B030 operates across -40°C ~ 125°C, matching the original RN214-1.5-02 temperature range. RN214-1.5-02-6M8 operates only to 100°C maximum, making it unsuitable for higher-temperature applications.

Q: How do DC resistance differences affect circuit performance?

A: RN214-1.5-02-6M8 has lower DC resistance (123 mOhm vs. 130 mOhm), reducing power dissipation and heat generation. B82732R2172B030 has higher DC resistance (190 mOhm), increasing power dissipation. For applications sensitive to power loss or thermal management, RN214-1.5-02-6M8 is preferred. For applications with adequate thermal headroom, B82732R2172B030 remains functional.

Q: What compliance certifications apply to each substitute?

A: RN214-1.5-02-6M8 holds ENEC, UR, and VDE approvals with ROHS3 compliance. B82732R2172B030 holds identical certifications (ENEC, UR, VDE) with ROHS3 compliance. Both meet the regulatory requirements of the original part and expand certification coverage.

Q: Can current rating differences affect substitution suitability?

A: Current ratings of 1.5A (RN214-1.5-02-6M8) and 1.7A (B82732R2172B030) both meet or exceed the original 1.5A specification. Higher current ratings provide design margin and do not create incompatibility. Component selection should be based on actual circuit current requirements and thermal considerations.
