S3483R-330M

Part Overview

The S3483R-330M is a 33 µH shielded drum core, wirewound inductor manufactured by API Delevan Inc. This surface mount inductor is rated for 720 mA continuous current with a maximum DC resistance of 250 mOhm. The component is actively produced and ROHS3 compliant, making it suitable for modern electronic applications requiring stable inductance in the 33 µH range.

Alternative models become necessary when inventory constraints exist, when specific thermal or frequency characteristics are required, or when design flexibility allows for components with slightly different package dimensions while maintaining equivalent electrical performance.

Key Parameters

Substitute Part Grouping Explanation

The SRR0604-330KL from Bourns Inc. qualifies as a functional equivalent based on the following critical parameters:

Matching Electrical Specifications:

• Identical inductance value: 33 µH
• Identical DC resistance: 250 mOhm Max
• Comparable current rating: 700 mA (S3483R-330M rated at 720 mA)
• Ferrite core, shielded construction
• Surface mount packaging

Tolerance Consideration: The S3483R-330M operates with ±20% tolerance, while the SRR0604-330KL provides tighter ±10% tolerance, making it suitable for applications where inductance precision is beneficial.

Dimensional Variance: The substitute part has smaller footprint dimensions (6.50mm x 6.50mm versus 7.20mm x 7.20mm) and greater height (4.80mm versus 3.50mm). These differences require layout verification but do not affect electrical equivalency.

Parameter Comparison

Engineering Selection Recommendations

Both the S3483R-330M and SRR0604-330KL are active products from established manufacturers, maintaining full ROHS3 compliance and REACH unaffected status. Selection between these components depends on application-specific constraints rather than regulatory or manufacturing status considerations.

The S3483R-330M provides a lower maximum height (3.50mm) when vertical space is constrained. The SRR0604-330KL offers a smaller planar footprint (6.50mm versus 7.20mm) when board area is at a premium, though it requires additional vertical clearance. Both components support unlimited moisture sensitivity handling, eliminating special storage requirements.

The SRR0604-330KL's extended operating temperature range (-40°C to 125°C versus -20°C to 85°C) and tighter inductance tolerance (±10% versus ±20%) are available as secondary considerations if the application environment or precision requirements align with these enhanced specifications.

Frequently Asked Questions (FAQ)

Can the SRR0604-330KL directly replace the S3483R-330M on an existing PCB?

Direct replacement requires board layout evaluation. The substitute has a smaller planar footprint (6.50mm versus 7.20mm) but greater height (4.80mm versus 3.50mm). PCB pads and surrounding component clearances must be verified before substitution.

What is the difference in current handling between these inductors?

The S3483R-330M is rated for 720 mA continuous current; the SRR0604-330KL is rated for 700 mA. For applications operating below 700 mA, both inductors are equivalent. Applications requiring sustained current above 700 mA are limited to the S3483R-330M.

How do the tolerance specifications affect circuit performance?

The S3483R-330M has ±20% inductance tolerance; the SRR0604-330KL has ±10%. In circuits where inductance precision is critical, the tighter tolerance of the substitute provides better performance consistency. For applications tolerant of wider inductance variation, both components are functionally equivalent.

Are there packaging or terminal configuration differences?

Both inductors use nonstandard packages as surface mount components. The SRR0604-330KL features corner terminals, while the S3483R-330M does not note this specification. Terminal configuration differences require soldering process evaluation if automated assembly is used.

What temperature range should be considered for component selection?

The S3483R-330M operates from -20°C to 85°C; the SRR0604-330KL from -40°C to 125°C. Applications within the overlapping range (-20°C to 85°C) can use either component. Only applications requiring below -20°C or above 85°C operation are limited to the SRR0604-330KL.

Are both components compliant with environmental regulations?

Both inductors are ROHS3 compliant and REACH unaffected, meeting current environmental requirements for products sold in regulated markets.
