Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SWPA4030S2R2NT is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value: 2.2 µH (tolerance variations acceptable within design margin)
• DC Resistance: 39 mOhm maximum
• Current Rating: minimum 2.95 A continuous
• Saturation Current (Isat): minimum 5.8 A
• Operating Temperature Range: -40°C to 125°C minimum

Mechanical Equivalence Requirements:

• Package dimensions: 4.00 mm L x 4.00 mm W
• Height (seated): 3.00 mm maximum
• Mounting Type: Surface Mount
• Core Material: Ferrite
• Inductance test frequency: 100 kHz

Compliance Requirements:

• Product Status: Active
• Packaging: Tape & Reel (TR)

The SDCL1V4030-2R2M-R from Eaton - Electronics Division meets these substitution criteria with equivalent electrical performance and identical mechanical compatibility.

Engineering Selection Recommendations

SWPA4030S2R2NT (Primary Selection)

The SWPA4030S2R2NT remains the primary component choice when the following conditions apply:

• Applications requiring fully shielded inductor construction for electromagnetic interference mitigation
• Designs operating at or near the 2.95 A continuous current rating
• Systems where saturation current margin of 5.8 A is specified
• Inductance tolerance of ±30% is acceptable for the application

SDCL1V4030-2R2M-R (Substitute Selection)

The SDCL1V4030-2R2M-R from Eaton - Electronics Division is substitutable when the following conditions apply:

• Applications where semi-shielded construction is acceptable
• Designs operating below 2.8 A continuous current
• Systems where saturation current margin of 5.0 A is sufficient
• Tighter inductance tolerance of ±20% provides design advantage
• Both parts maintain identical mechanical footprint and thermal operating range
• Both parts are active production status with established supply chains

Compliance Considerations

Both parts are classified under ECCN EAR99 and HTSUS 8504.50.8000. The SDCL1V4030-2R2M-R carries ROHS3 compliance and REACH Unaffected status. The SWPA4030S2R2NT does not specify these compliance certifications in the provided data.

Frequently Asked Questions (FAQ)

Q: Can the SDCL1V4030-2R2M-R directly replace the SWPA4030S2R2NT in all applications?

A: Direct substitution is possible only when the application does not require fully shielded inductor construction and operates below 2.8 A continuous current. The semi-shielded design of the SDCL1V4030-2R2M-R may introduce different electromagnetic field characteristics compared to the fully shielded SWPA4030S2R2NT. The lower saturation current (5.0 A versus 5.8 A) must be verified against circuit design margins.

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

A: The SWPA4030S2R2NT features full shielding, which provides superior electromagnetic interference containment. The SDCL1V4030-2R2M-R is semi-shielded, offering reduced EMI containment but potentially lower cost and different thermal characteristics. Selection depends on circuit layout requirements and EMI specifications.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts share identical surface mount package dimensions of 4.00 mm length x 4.00 mm width with a maximum seated height of 3.00 mm. Both are supplied in Tape & Reel packaging. PCB footprints are interchangeable.

Q: What is the impact of the current rating difference?

A: The SWPA4030S2R2NT is rated for 2.95 A continuous current, while the SDCL1V4030-2R2M-R is rated for 2.8 A. This 0.15 A difference represents approximately 5% lower capacity in the substitute part. Applications operating near the upper current limit of the main part cannot use the substitute without thermal and reliability reassessment.

Q: How do the saturation current ratings compare?

A: The SWPA4030S2R2NT saturates at 5.8 A, while the SDCL1V4030-2R2M-R saturates at 5.0 A. This 0.8 A difference affects circuit margin during transient conditions. Designs with saturation current specifications must account for this 13.8% reduction in the substitute part.

Q: Is the inductance tolerance difference significant?

A: The SWPA4030S2R2NT carries ±30% tolerance, while the SDCL1V4030-2R2M-R carries ±20% tolerance. The substitute part offers tighter tolerance control, which may provide design advantage in applications sensitive to inductance variation. Both parts are tested at 100 kHz.

Q: Are there compliance or certification differences?

A: The SDCL1V4030-2R2M-R specifies ROHS3 compliance and REACH Unaffected status. The SWPA4030S2R2NT does not include these certifications in the provided technical data. Applications with regulatory compliance requirements should verify certification status with the manufacturer.

Q: Can these parts be used interchangeably in high-frequency applications?

A: The SWPA4030S2R2NT specifies a self-resonant frequency of 52 MHz. The SDCL1V4030-2R2M-R does not provide self-resonant frequency data. Applications operating near or above 52 MHz require frequency response verification before substitution.
