Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SWPA5020S2R2NT is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value of 2.2 µH at 100 kHz test frequency
• Ferrite core material composition
• Surface mount package configuration
• Nonstandard package case classification
• Physical dimensions of 5.00mm x 5.00mm footprint

Secondary Compatibility Criteria:

• Current rating equal to or greater than 2.9 A
• DC resistance at or below 42mOhm maximum
• Saturation current (Isat) at or above 4 A
• Operating temperature range encompassing -40°C to 125°C
• Shielding classification (shielded or semi-shielded acceptable)
• Moisture sensitivity level MSL 1 (Unlimited)

Tolerance Considerations:

• Inductance tolerance of ±20% or tighter acceptable
• Parts with ±30% tolerance directly equivalent

The identified substitute parts meet these criteria while maintaining functional equivalence in typical circuit applications.

Parameter Comparison

Engineering Selection Recommendations

BWVS005050202R2M00 (Pulse Electronics): This substitute provides improved performance characteristics with a 3.2 A current rating exceeding the main part's 2.9 A specification. The DC resistance of 35 mOhm is lower than the 42 mOhm maximum of the SWPA5020S2R2NT, resulting in reduced power dissipation. The inductance tolerance is tightened to ±20%, providing greater precision. The extended operating temperature range of -55°C to 125°C offers broader environmental coverage. ROHS3 compliance and REACH unaffected status are documented. The height dimension increases to 2.20mm, which requires verification against PCB layout constraints. This part is suitable for applications requiring enhanced current handling and reduced losses.

SDCH1V5020-2R2M-R (Eaton - Electronics Division): This substitute maintains identical package height of 2.00mm, ensuring direct mechanical compatibility with the main part. The current rating of 3 A exceeds the 2.9 A requirement. The DC resistance of 45 mOhm is marginally higher than the 42 mOhm specification, representing a 7% increase in resistance. The saturation current of 3.8 A is slightly below the 4 A rating of the main part. Shielding is classified as semi-shielded rather than fully shielded, which may affect electromagnetic interference characteristics in sensitive applications. ROHS3 compliance and REACH unaffected status are documented. This part is suitable for applications where package height constraints are critical and semi-shielded performance is acceptable.

Frequently Asked Questions (FAQ)

Q: Can BWVS005050202R2M00 be used as a direct replacement for SWPA5020S2R2NT?

A: The BWVS005050202R2M00 is functionally equivalent for inductance and current rating requirements. The primary consideration is the increased height dimension of 2.20mm compared to 2.00mm. PCB layout and component clearance must be verified before substitution.

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

A: The BWVS005050202R2M00 has 35 mOhm DCR (lower), the SWPA5020S2R2NT has 42 mOhm DCR (main), and the SDCH1V5020-2R2M-R has 45 mOhm DCR (higher). Lower resistance reduces power dissipation and heat generation. Higher resistance increases power loss. Selection depends on thermal management requirements and efficiency specifications.

Q: How does shielding classification affect circuit performance?

A: The SWPA5020S2R2NT and BWVS005050202R2M00 are fully shielded, providing maximum electromagnetic interference suppression. The SDCH1V5020-2R2M-R is semi-shielded, offering reduced EMI containment. Fully shielded inductors are preferred in noise-sensitive applications. Semi-shielded inductors may be acceptable in less demanding environments.

Q: Are all three parts RoHS compliant?

A: The BWVS005050202R2M00 and SDCH1V5020-2R2M-R are explicitly ROHS3 compliant. The SWPA5020S2R2NT does not specify RoHS status in the provided documentation. Compliance verification with the component manufacturer is required if RoHS certification is mandatory for the application.

Q: What is the impact of inductance tolerance on circuit design?

A: The SWPA5020S2R2NT has ±30% tolerance, while both substitute parts have ±20% tolerance. Tighter tolerance reduces circuit performance variation and simplifies design margin calculations. Applications requiring precise inductance values benefit from the ±20% tolerance of substitute parts.

Q: Can SDCH1V5020-2R2M-R be used in applications requiring full shielding?

A: The SDCH1V5020-2R2M-R is semi-shielded, not fully shielded. Applications requiring complete electromagnetic containment should use the SWPA5020S2R2NT or BWVS005050202R2M00. Semi-shielded performance may be insufficient for high-frequency or noise-critical circuits.

Q: What are the temperature range implications for each part?

A: The SWPA5020S2R2NT and SDCH1V5020-2R2M-R operate from -40°C to 125°C. The BWVS005050202R2M00 extends the lower limit to -55°C. Applications requiring operation below -40°C require the BWVS005050202R2M00. Standard industrial applications typically operate within the -40°C to 125°C range.

Q: How do saturation current ratings compare?

A: The SWPA5020S2R2NT has 4 A Isat, BWVS005050202R2M00 has 3.4 A Isat, and SDCH1V5020-2R2M-R has 3.8 A Isat. Saturation current defines the maximum current before inductance degrades significantly. Applications with current transients or peak currents approaching these limits require careful evaluation.

Q: Are all parts available in Tape & Reel packaging?

A: All three parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. Inventory levels vary: SWPA5020S2R2NT (16,030 pcs), BWVS005050202R2M00 (8,836 pcs), and SDCH1V5020-2R2M-R (3,412 pcs).
