2. SRR0604-2R2ML (Bourns Inc.): Meets all primary criteria with current rating of 2.5 A and DC resistance of 32 mOhm. Includes corner terminal configuration and extended operating temperature range (-40°C to 125°C).

Parameter Comparison

Engineering Selection Recommendations

B82472G4222M000 (EPCOS - TDK Electronics): This substitute provides superior electrical performance with lower DC resistance (25 mOhm vs. 28 mOhm) and higher current rating (2.9 A vs. 2.66 A). The extended operating temperature range (-55°C to 125°C) accommodates applications requiring broader thermal performance. All regulatory compliance requirements (RoHS3, REACH Unaffected, EAR99) are met. This part is suitable for applications where enhanced thermal stability and lower losses are beneficial.

SRR0604-2R2ML (Bourns Inc.): This substitute meets the minimum current requirement (2.5 A) with acceptable DC resistance (32 mOhm). The extended operating temperature range (-40°C to 125°C) supports wider application environments. The corner terminal configuration represents a mechanical design variation that must be verified for PCB layout compatibility. All regulatory compliance requirements (RoHS3, REACH Unaffected, EAR99) are met. This part is suitable for applications where the corner terminal design is compatible with existing board layouts.

Both substitutes maintain active product status and equivalent packaging in tape and reel format, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can B82472G4222M000 be used as a direct replacement for S3483R-2R2M?

A: Yes. Both components share identical inductance (2.2 µH), tolerance (±20%), core material (ferrite), shielding (shielded), and mounting type (surface mount). The B82472G4222M000 provides improved electrical characteristics with lower DC resistance and higher current rating, making it functionally equivalent and electrically superior for the specified application parameters.

Q: What is the primary difference between SRR0604-2R2ML and the original S3483R-2R2M?

A: The SRR0604-2R2ML features corner terminals instead of standard terminals and has a slightly higher maximum DC resistance (32 mOhm vs. 28 mOhm). The current rating is 2.5 A compared to 2.66 A. PCB layout compatibility must be verified due to the corner terminal configuration before implementation.

Q: Are all three parts RoHS3 compliant?

A: Yes. The S3483R-2R2M, B82472G4222M000, and SRR0604-2R2ML are all RoHS3 compliant with MSL 1 (unlimited) moisture sensitivity ratings, ensuring compliance with current environmental and reliability standards.

Q: Which substitute offers the best thermal performance?

A: Both B82472G4222M000 and SRR0604-2R2ML provide extended operating temperature ranges (-55°C to 125°C and -40°C to 125°C respectively) compared to the original part (-20°C to 85°C). The B82472G4222M000 offers the widest temperature range and lowest DC resistance, providing superior thermal and electrical performance.

Q: Can the SRR0604-2R2ML corner terminal design be accommodated on existing PCBs designed for S3483R-2R2M?

A: PCB layout compatibility must be individually verified. The corner terminal configuration represents a mechanical design variation that may require board layout modifications. Physical dimensions should be compared against the original design specifications before implementation.

Q: What is the inductance frequency test condition for these parts?

A: The S3483R-2R2M and B82472G4222M000 are tested at 100 kHz. The SRR0604-2R2ML is tested at 1 kHz. This difference in test frequency should be considered when comparing measured inductance values across different measurement conditions.
