Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RN232-4-02 are identified based on the following critical parameters that must align for functional equivalence:

• Inductance value: 3.3 mH @ 10 kHz
• Current rating: 4A maximum
• Number of lines: 2-line configuration
• Mounting type: Through hole
• Filter classification: Power line common mode choke
• Package configuration: Vertical, 4-pin package

Two active substitute parts meet these criteria: RN232-4-02-3M3 (direct manufacturer variant from Schaffner EMC Inc.) and B82724J2402N001 (equivalent from EPCOS - TDK Electronics). Both maintain the core electrical specifications and mechanical form factor required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

RN232-4-02-3M3 is the primary substitute, being the direct active variant from the original manufacturer Schaffner EMC Inc. within the same RN series. This part maintains identical electrical specifications and mechanical compatibility while offering active product status and ROHS3 compliance.

B82724J2402N001 from EPCOS - TDK Electronics serves as a cross-manufacturer equivalent. While DC resistance is slightly higher (65 mOhm vs. 54 mOhm typical) and AC voltage rating is lower (250V vs. 300V), the part meets all core functional requirements. This option provides extended operating temperature range (-40°C to 125°C) and is available in higher inventory quantities. Both substitute parts carry equivalent international approvals (ENEC, UR, VDE).

Selection between the two substitutes depends on application-specific requirements: choose RN232-4-02-3M3 for manufacturer continuity and lower DCR; choose B82724J2402N001 for extended temperature range and higher stock availability.

Frequently Asked Questions (FAQ)

Q: Can RN232-4-02-3M3 be used as a direct replacement for RN232-4-02?

A: Yes. RN232-4-02-3M3 is the active equivalent from Schaffner EMC Inc. with identical inductance (3.3 mH @ 10 kHz), current rating (4A), line configuration (2-line), and through-hole mounting. Electrical and mechanical compatibility is confirmed.

Q: What is the difference between RN232-4-02-3M3 and B82724J2402N001?

A: Both parts share identical inductance, current rating, and mounting configuration. Key differences are: RN232-4-02-3M3 has lower DC resistance (54 mOhm typical vs. 65 mOhm) and higher AC voltage rating (300V vs. 250V); B82724J2402N001 offers extended operating temperature range (-40°C to 125°C vs. -40°C to 100°C). Both carry equivalent international certifications.

Q: Are both substitute parts RoHS compliant?

A: Yes. RN232-4-02-3M3 is ROHS3 compliant. B82724J2402N001 is ROHS3 compliant. Both meet current RoHS requirements.

Q: What packaging formats are available for the substitute parts?
