Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN232-2.5-02 is determined by the following critical parameters:

• Inductance value: 5.6 mH @ 10 kHz (exact match required)
• Current rating: 2.5A maximum (equal or higher acceptable)
• Number of lines: 2-line configuration (exact match required)
• Mounting type: Through hole (exact match required)
• Filter classification: Power line common mode choke (exact match required)
• AC voltage rating: minimum 250V (300V preferred for margin)
• Operating temperature: minimum -40°C to 100°C overlap required
• Regulatory compliance: ENEC, UR, VDE approvals maintained

Two active substitute parts meet these criteria and are available in production inventory.

Parameter Comparison

Engineering Selection Recommendations

RN232-2.5-02-5M6 is the primary substitute for the obsolete RN232-2.5-02. Both parts are manufactured by Schaffner EMC Inc., share identical electrical specifications (5.6 mH @ 10 kHz, 2.5A rating), and maintain equivalent AC voltage ratings (300V). The RN232-2.5-02-5M6 is active in production with higher inventory availability (1140 units) and carries ROHS3 compliance with ENEC, UR, and VDE approvals. Physical dimensions are comparable, with height difference of 0.055" (1.40mm).

B82724J2252N001 manufactured by EPCOS - TDK Electronics serves as an alternative substitute. This part meets all critical electrical parameters (5.6 mH @ 10 kHz, 2.5A) and maintains through-hole mounting compatibility. The AC voltage rating is 250V, which is 50V lower than the primary substitute. DC resistance is higher at 125 mOhm typical versus 86 mOhm for the RN232-2.5-02-5M6. Operating temperature range extends to 125°C. Physical dimensions are within 0.012" (0.30mm) length and 0.019" (0.50mm) width of the primary substitute. ROHS3 compliance and ENEC, UR, VDE approvals are maintained.

Both substitutes are active production parts with established supply chains and regulatory certifications suitable for direct replacement in power line filtering applications.

Frequently Asked Questions (FAQ)

Q: Can RN232-2.5-02-5M6 be used as a direct replacement for RN232-2.5-02?

A: Yes. Both parts share identical inductance (5.6 mH @ 10 kHz), current rating (2.5A), line configuration (2-line), mounting type (through hole), and AC voltage rating (300V). The RN232-2.5-02-5M6 is the active production equivalent with higher inventory availability.

Q: What is the difference between RN232-2.5-02-5M6 and B82724J2252N001?

A: Both parts meet the core electrical specifications (5.6 mH @ 10 kHz, 2.5A, 2-line through-hole). Key differences are: manufacturer (Schaffner vs. EPCOS-TDK), AC voltage rating (300V vs. 250V), DC resistance (86 mOhm vs. 125 mOhm typical), and operating temperature range (-40°C to 100°C vs. -40°C to 125°C). Physical dimensions differ by less than 0.02" in length and width.

Q: Are there packaging considerations when substituting these parts?

A: RN232-2.5-02-5M6 is supplied in tube packaging, while B82724J2252N001 is supplied in tray packaging. Both are through-hole mounted components with comparable footprints. Verify PCB layout compatibility with the specified dimensions before procurement.

Q: Do all substitute parts maintain the same regulatory compliance?

A: Both active substitutes carry ROHS3 compliance and ENEC, UR, VDE approvals. The original RN232-2.5-02 is listed as RoHS Compliant. All parts are EAR99 classified and REACH unaffected or affected as specified.

Q: Which substitute should be selected for new designs?

A: RN232-2.5-02-5M6 is recommended for new designs as it is the direct Schaffner equivalent with identical electrical and thermal specifications, higher inventory availability, and established supply continuity. B82724J2252N001 is suitable where EPCOS-TDK component qualification is required or where the extended operating temperature range (to 125°C) provides design margin.

Q: What is the DC resistance impact of using B82724J2252N001?

A: B82724J2252N001 has a typical DC resistance of 125 mOhm compared to 86 mOhm for RN232-2.5-02-5M6. This 39 mOhm difference results in increased power dissipation at rated current. At 2.5A, the additional dissipation is approximately 0.24W. Verify thermal design margins in the application before substitution.
