Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RN152-2-02 are qualified based on the following critical parameters:

• Inductance value: 18 mH @ 10 kHz (exact match required)
• Number of lines: 2 (exact match required)
• Current rating: 2A minimum
• Mounting type: Through Hole (exact match required)
• Package configuration: Horizontal, 4 PC Pin (exact match required)
• DC resistance: Within acceptable tolerance range (330–350 mOhm)
• Voltage rating: AC 250V minimum
• Operating temperature range: Minimum -40°C to +100°C

The RN152-2-02-18M is a direct manufacturer equivalent from Schaffner EMC Inc. with identical electrical specifications and form factor, differing only in packaging format and product status (Active vs. Obsolete).

The B82725A2202N001 from EPCOS - TDK Electronics is a similar substitute meeting all critical electrical and mechanical parameters, with minor variations in DC resistance (330 mOhm vs. 350 mOhm) and physical dimensions within acceptable tolerance.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the RN152-2-02, the RN152-2-02-18M is the primary substitute choice. This part is manufactured by the same supplier, maintains identical electrical specifications and physical dimensions, and carries Active product status with enhanced compliance certifications (ROHS3 and ENEC approval). The higher AC voltage rating (300V vs. 250V) provides additional design margin.

The B82725A2202N001 from EPCOS - TDK Electronics is a qualified alternative when supply constraints or design requirements necessitate a second-source component. This part meets all critical electrical parameters with a lower DC resistance value (330 mOhm), maintains the same current and inductance ratings, and is certified by equivalent regulatory bodies (ENEC, UR, VDE). Physical dimensions are within acceptable tolerance for through-hole PCB mounting. The REACH Affected status requires compliance verification for applications subject to REACH regulations.

Both substitute parts are currently in active production with confirmed inventory availability, ensuring long-term supply reliability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the RN152-2-02-18M be used as a direct replacement for the RN152-2-02?

A: Yes. The RN152-2-02-18M is a direct equivalent with identical inductance (18 mH @ 10 kHz), current rating (2A), DC resistance (350 mOhm), mounting type (Through Hole), and physical dimensions (43.00 mm L x 41.80 mm W x 25.30 mm H). The primary difference is product status (Active vs. Obsolete) and packaging format (Tube vs. standard). No circuit modifications are required.

Q: What are the key differences between the RN152-2-02-18M and B82725A2202N001?

A: Both parts share identical inductance, current rating, and mounting specifications. The B82725A2202N001 has a lower DC resistance (330 mOhm vs. 350 mOhm), slightly larger physical dimensions (44.00 mm L x 42.40 mm W), and is manufactured by EPCOS - TDK Electronics rather than Schaffner. The B82725A2202N001 carries REACH Affected status, requiring compliance assessment for regulated applications.

Q: Are there any PCB layout considerations when substituting to the B82725A2202N001?

A: The B82725A2202N001 has marginally larger footprint dimensions (44.00 mm x 42.40 mm vs. 43.00 mm x 41.80 mm). Verify that PCB pad spacing and component clearances accommodate the slightly larger envelope. The 4-pin through-hole configuration remains identical across all three parts.

Q: Which substitute part should be selected for new designs?

A: For new designs, the RN152-2-02-18M is recommended as the primary choice due to identical specifications, Active product status, and established supply chain from the original manufacturer. The B82725A2202N001 is suitable as a secondary source option when supply diversification is required.

Q: Do all three parts meet the same regulatory certifications?

A: The RN152-2-02 carries UR and VDE approvals. The RN152-2-02-18M adds ENEC certification (ENEC, UR, VDE). The B82725A2202N001 also carries ENEC, UR, and VDE approvals. All three parts are RoHS compliant. Verify REACH compliance requirements for the B82725A2202N001 in applications subject to REACH regulations.
