Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN142-2-02 is determined by the following critical parameters:

• Inductance value: 6.8 mH @ 10 kHz (exact match required)
• Number of lines: 2 (exact match required)
• Current rating: 2A minimum
• DC resistance: Within acceptable tolerance range
• Voltage rating: AC 250V minimum
• Operating temperature range: Must encompass -40°C to 125°C or be compatible with application requirements
• Mounting type: Through Hole (exact match required)
• Package configuration: Horizontal, 4 PC Pin (exact match required)
• Physical dimensions: Compatible footprint for PCB placement

The identified substitute parts meet these core electrical and mechanical criteria, enabling direct functional replacement in power line filtering circuits.

Parameter Comparison

Engineering Selection Recommendations

RN142-2-02-6M8 (Direct Schaffner Equivalent): This part is the primary substitute, manufactured by Schaffner EMC Inc. with Active product status. It maintains identical inductance, current rating, and physical dimensions. The DC resistance variance (192 mOhm vs. 190 mOhm) is within typical manufacturing tolerance. The higher AC voltage rating (300V vs. 250V) provides additional margin. The operating temperature range (-40°C to 100°C) is narrower than the original; applications requiring operation above 100°C must be evaluated against specific circuit requirements. This part carries ENEC, UR, and VDE certifications and ROHS3 compliance.

B82724A2202N001 (Cross-Manufacturer Alternative): This EPCOS - TDK Electronics part provides an alternative from a different manufacturer while maintaining identical electrical specifications for inductance, current rating, and frequency response. The DC resistance is lower (170 mOhm), which may reduce insertion loss in power line filtering circuits. The operating temperature range matches the original (-40°C to 125°C). Physical dimensions are nearly identical with a 0.01" height difference (19.70mm vs. 20.00mm), which is negligible for through-hole PCB applications. This part carries ENEC, UR, and VDE certifications and ROHS3 compliance. REACH Affected status indicates regulatory documentation requirements for certain jurisdictions.

Frequently Asked Questions (FAQ)

Q: Can RN142-2-02-6M8 be used as a direct replacement for RN142-2-02?

A: Yes. Both parts share identical inductance (6.8 mH @ 10 kHz), current rating (2A), number of lines (2), mounting type (through-hole), and physical footprint (33.10mm x 32.50mm). DC resistance values (190 mOhm vs. 192 mOhm) are within acceptable tolerance. The primary consideration is the operating temperature range: RN142-2-02-6M8 operates to 100°C maximum, compared to 125°C for the original. Verify application temperature requirements before selection.

Q: What is the difference between RN142-2-02-6M8 and B82724A2202N001?

A: Both are functionally equivalent for power line filtering with 6.8 mH inductance and 2A current rating. Key differences include manufacturer (Schaffner vs. EPCOS-TDK), DC resistance (192 mOhm vs. 170 mOhm), and regulatory status (REACH Unaffected vs. REACH Affected). The B82724A2202N001 offers lower insertion loss due to reduced DC resistance and matches the original operating temperature range (-40°C to 125°C). Selection depends on supply chain availability, regulatory requirements, and performance priorities.

Q: Are the physical dimensions compatible with the original PCB layout?

A: Yes. All three parts maintain the same footprint (33.10mm x 1.280" W) and horizontal 4-pin configuration. Height differences are minimal: RN142-2-02 and RN142-2-02-6M8 are 20.00mm, while B82724A2202N001 is 19.70mm. These variations do not affect PCB placement or clearance in standard through-hole applications.

Q: What certifications apply to each substitute part?

A: RN142-2-02-6M8 carries ENEC, UR, and VDE approvals with ROHS3 compliance. B82724A2202N001 carries ENEC, UR, and VDE approvals with ROHS3 compliance. Both exceed the original part's certification scope (UR, VDE). Verify that selected certifications meet application and regional regulatory requirements.

Q: Does the lower DC resistance of B82724A2202N001 affect circuit performance?

A: Lower DC resistance (170 mOhm vs. 190 mOhm) reduces power dissipation and insertion loss in the common mode choke. This is a performance advantage in power line filtering applications. No circuit redesign is required; the part functions as a direct electrical substitute with improved efficiency characteristics.
