Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S3483R-3R3M is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Inductance value must be 3.3 µH within ±20% tolerance
• Current rating must meet or exceed 2.26 A
• DC resistance must not exceed 35 mOhm maximum
• Core material must be ferrite with shielding configuration
• Frequency test conditions and self-resonant frequency characteristics must support the intended application frequency range

Mechanical Compatibility Criteria:

• Mounting type must be surface mount
• Package classification must be nonstandard drum core type
• Physical dimensions must accommodate board layout constraints
• Terminal configuration must be compatible with PCB footprint design

Regulatory & Environmental Criteria:

• RoHS3 compliance required
• Moisture sensitivity level MSL 1 (Unlimited)
• Operating temperature range must encompass or match -20°C to 85°C specification
• REACH unaffected status maintained

The SRR0604-3R3ML from Bourns Inc. qualifies as a substitute based on matching inductance, exceeding current rating requirements, maintaining ferrite shielded core construction, and meeting all regulatory compliance standards.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: S3483R-3R3M

The S3483R-3R3M maintains Active product status with full ROHS3 compliance and REACH unaffected designation. This component is suitable for applications requiring the specified 3.3 µH inductance with 2.26 A current handling and 35 mOhm maximum DC resistance within the -20°C to 85°C operating window.

Substitute Part: SRR0604-3R3ML

The SRR0604-3R3ML from Bourns Inc. is qualified as an equivalent substitute. This part maintains identical inductance and tolerance specifications while providing superior current rating (2.3 A versus 2.26 A) and extended operating temperature range (-40°C to 125°C). The substitute exhibits higher DC resistance at 50 mOhm maximum, which represents a 43% increase over the primary part specification. Both components maintain ROHS3 compliance and MSL 1 moisture sensitivity rating.

Physical dimensions differ: the SRR0604-3R3ML footprint is smaller in lateral dimensions (6.50mm versus 7.20mm) but taller in seated height (4.80mm versus 3.50mm). PCB layout compatibility must be verified for height clearance and footprint accommodation.

Both parts are classified as Active with equivalent regulatory compliance. Selection between primary and substitute should be based on specific application requirements regarding DC resistance tolerance, thermal operating range, and available PCB space for component height.

Frequently Asked Questions (FAQ)

Q: Can the SRR0604-3R3ML directly replace the S3483R-3R3M in all applications?

A: Electrical substitution is valid for applications where the 50 mOhm DC resistance of the SRR0604-3R3ML is acceptable compared to the 35 mOhm specification of the S3483R-3R3M. Mechanical substitution requires verification of PCB footprint compatibility, particularly the increased seated height of 4.80mm versus 3.50mm and the reduced lateral dimensions of 6.50mm versus 7.20mm.

Q: What is the significance of the DC resistance difference between these parts?

A: The SRR0604-3R3ML exhibits 50 mOhm maximum DC resistance compared to 35 mOhm for the S3483R-3R3M. This 15 mOhm difference affects power dissipation and thermal performance. Applications sensitive to inductor losses or operating near thermal limits should evaluate this parameter against design margins.

Q: Are both parts suitable for the same temperature range applications?

A: The S3483R-3R3M operates from -20°C to 85°C. The SRR0604-3R3ML extends this range to -40°C to 125°C. For applications within the -20°C to 85°C window, both parts are compatible. For applications requiring extended temperature operation, only the SRR0604-3R3ML qualifies.

Q: What does the corner terminals designation mean for the SRR0604-3R3ML?

A: The corner terminals configuration indicates the terminal placement geometry on the nonstandard package. PCB footprint design must accommodate this specific terminal arrangement. Verify footprint compatibility before implementing the substitute.

Q: Do both parts maintain equivalent regulatory compliance?

A: Yes. Both the S3483R-3R3M and SRR0604-3R3ML are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited) for moisture sensitivity. Regulatory requirements are equivalent between primary and substitute parts.

Q: What is the inductance frequency test difference between these parts?

A: The S3483R-3R3M specifies inductance measurement at 100 kHz, while the SRR0604-3R3ML uses 1 kHz test frequency. Both maintain ±20% tolerance. The different test frequencies reflect manufacturer measurement standards and do not affect substitution validity for the specified inductance value.
