Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN152-8-02 is determined by the following critical parameters:

• Inductance Value: 2.7 mH (measurement frequency may vary: 1 kHz or 10 kHz)
• Number of Lines: 2-line configuration
• Current Rating: 8A minimum
• DC Resistance: 22 mOhm (Typ)
• Mounting Type: Through Hole
• Package Configuration: Horizontal, 4 PC Pin
• Voltage Rating - AC: Minimum 250V
• Operating Temperature Range: Must support -40°C to 125°C or equivalent
• Regulatory Compliance: UR and VDE certifications

Two substitute parts meet these criteria:

RN152-8-02-2M7 (Direct Manufacturer Substitute): Same manufacturer (Schaffner EMC Inc.), same series (RN152), active product status. Inductance measured at 10 kHz instead of 1 kHz. Voltage rating increased to 300V. Operating temperature range -40°C to 100°C. Enhanced compliance with ENEC, UR, VDE certifications. Packaged in Tube format.

B82725A2802N001 (Similar Manufacturer Substitute): Alternative manufacturer (EPCOS - TDK Electronics), different series (B82725). Inductance measured at 10 kHz. Voltage rating 250V. Operating temperature range -40°C to 125°C. Compliance with ENEC, UR, VDE certifications. Packaged in Tray format. Dimensions slightly larger (44.00mm L x 42.40mm W vs. 43.00mm x 41.80mm).

Parameter Comparison

Engineering Selection Recommendations

RN152-8-02-2M7 is the primary substitute option. As a direct manufacturer part from Schaffner EMC Inc. within the same RN152 series, it maintains design continuity while offering active product status and enhanced regulatory compliance (ENEC certification addition). The increased AC voltage rating (300V vs. 250V) provides additional safety margin. The reduced operating temperature upper limit (100°C vs. 125°C) requires verification against specific application thermal requirements. Identical physical dimensions and pin configuration ensure direct PCB compatibility.

B82725A2802N001 serves as an alternative when RN152-8-02-2M7 availability is constrained. Manufactured by EPCOS - TDK Electronics, this part maintains all critical electrical parameters and preserves the full operating temperature range (-40°C to 125°C). Dimensional differences (44.00mm L x 42.40mm W vs. 43.00mm x 41.80mm) require PCB layout verification for clearance compatibility. REACH Affected status indicates substance of concern documentation requirements for this alternative.

Both substitutes maintain 2-line configuration, 8A current rating, 22 mOhm DC resistance, through-hole mounting, and horizontal 4-pin package format. Selection between them depends on thermal operating requirements, PCB space constraints, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can RN152-8-02-2M7 replace RN152-8-02 in all applications?

A: RN152-8-02-2M7 is compatible for applications where the operating temperature does not exceed 100°C. The main part supports -40°C to 125°C, while the substitute supports -40°C to 100°C. Verify your application's maximum operating temperature before selection. All other electrical and mechanical parameters are equivalent.

Q: What is the difference between inductance measured at 1 kHz versus 10 kHz?

A: Both substitute parts specify inductance at 10 kHz instead of 1 kHz. Inductance values can vary slightly across frequency ranges due to core material characteristics. The 2.7 mH specification remains consistent across both measurement frequencies for these components, confirming functional equivalence for power line filtering applications.

Q: Are the physical dimensions of B82725A2802N001 compatible with RN152-8-02 PCB layouts?

A: B82725A2802N001 has slightly larger dimensions (44.00mm L x 42.40mm W) compared to RN152-8-02 (43.00mm L x 41.80mm W). Height is marginally smaller (25.00mm vs. 25.30mm). PCB layout verification is required to confirm clearance compatibility, particularly in space-constrained designs. Pin configuration remains identical (Horizontal, 4 PC Pin).

Q: What does REACH Affected status mean for B82725A2802N001?

A: REACH Affected indicates the component contains substances of concern requiring compliance documentation under EU REACH regulations. This does not prevent use but requires proper substance declaration and documentation in supply chain management. RN152-8-02-2M7 carries REACH Unaffected status, simplifying regulatory documentation.

Q: Can I use either substitute interchangeably?

A: Both substitutes meet the core electrical specifications (2.7 mH, 2-line, 8A, 22 mOhm DCR, 250V+ AC rating). Selection depends on three factors: (1) operating temperature requirements—use RN152-8-02-2M7 for applications up to 100°C, or B82725A2802N001 for up to 125°C; (2) PCB space—verify dimensional compatibility; (3) regulatory requirements—RN152-8-02-2M7 simplifies REACH compliance. Both maintain UR and VDE certifications.
