Substitute Part Grouping Explanation

Substitute parts for the SWPA252012S2R2MT are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 2.2 µH (±20% tolerance)
• Core material: Ferrite
• Mounting type: Surface Mount
• Physical dimensions: 0.098" L × 0.079" W (2.50mm × 2.00mm)
• Moisture sensitivity level: 1 (Unlimited)
• Operating temperature range: Minimum -40°C to 125°C

Secondary Compatibility Parameters:

• Current rating: Equal to or greater than 1.15 A
• DC resistance: Lower or equal to 216mOhm
• Saturation current (Isat): Equal to or greater than 2.07 A
• Shielding: Shielded or Semi-Shielded configuration

The substitute parts BWVF002520122R2M00 and SDCL1V2512-2R2M-R meet these criteria with variations in current handling capability, DC resistance, and shielding configuration.

Parameter Comparison

Engineering Selection Recommendations

BWVF002520122R2M00 (Pulse Electronics): This substitute provides superior electrical performance with 1.8 A current rating and significantly lower DC resistance of 80 mOhm compared to the main part's 216 mOhm. The extended operating temperature range (-55°C to 125°C) offers broader environmental compatibility. The shielded configuration matches the main part's EMI characteristics. This part is suitable for applications where lower power dissipation and higher current capacity are beneficial. RoHS3 compliance and REACH unaffected status confirm regulatory alignment.

SDCL1V2512-2R2M-R (Eaton - Electronics Division): This substitute offers intermediate electrical performance with 1.7 A current rating and 106 mOhm DC resistance, representing a middle ground between the main part and the Pulse Electronics alternative. The semi-shielded configuration provides reduced EMI shielding compared to the fully shielded main part. Operating temperature range matches the main part at -40°C to 125°C. RoHS compliance and REACH unaffected status confirm regulatory alignment. This part is suitable for applications where moderate current capacity and reduced DC resistance are required with acceptable EMI performance trade-offs.

All three parts share identical inductance values, tolerance specifications, physical dimensions, and MSL ratings, confirming mechanical and environmental compatibility within the 1008 (2520 Metric) package footprint.

Frequently Asked Questions (FAQ)

Q: Can BWVF002520122R2M00 be used as a direct replacement for SWPA252012S2R2MT?

A: Yes, within the constraints of your application's current and thermal requirements. Both parts share the same 2.2 µH inductance, ±20% tolerance, ferrite core material, shielded configuration, and 1008 (2520 Metric) package dimensions. The BWVF002520122R2M00 provides higher current rating (1.8 A vs. 1.15 A) and lower DC resistance (80 mOhm vs. 216 mOhm), resulting in reduced power dissipation. Verify that your circuit design does not depend on the higher DC resistance of the original part.

Q: What are the differences between the SDCL1V2512-2R2M-R and SWPA252012S2R2MT?

A: The primary differences are: (1) Current rating: 1.7 A versus 1.15 A; (2) DC resistance: 106 mOhm versus 216 mOhm; (3) Shielding: Semi-Shielded versus Shielded; (4) Saturation current: 1.9 A versus 2.07 A. The SDCL1V2512-2R2M-R provides improved current handling and lower losses but with reduced EMI shielding. Both parts operate across -40°C to 125°C and share identical inductance and package specifications.

Q: Why does BWVF002520122R2M00 have lower saturation current (1.8 A) than its rated current (1.8 A)?

A: The saturation current specification indicates the current level at which the inductor's inductance begins to degrade due to core saturation. In this case, the saturation current equals the rated current, meaning the part reaches saturation at its maximum continuous current rating. This is a valid design specification and does not indicate a defect. Verify your application's peak current requirements do not exceed this threshold.

Q: Are all three parts RoHS compliant?

A: The SWPA252012S2R2MT does not specify RoHS status in the provided data. The BWVF002520122R2M00 is RoHS3 compliant. The SDCL1V2512-2R2M-R is RoHS compliant. Confirm RoHS requirements with your procurement specifications before final part selection.

Q: Can the SDCL1V2512-2R2M-R semi-shielded configuration replace the fully shielded SWPA252012S2R2MT in EMI-sensitive applications?

A: Semi-shielded inductors provide reduced electromagnetic interference containment compared to fully shielded designs. In applications where EMI performance is critical, the reduced shielding of the SDCL1V2512-2R2M-R may not provide equivalent performance. Evaluate your circuit's EMI requirements and conduct testing if electromagnetic compatibility is a design constraint.

Q: What is the physical height difference between these parts?

A: SWPA252012S2R2MT and SDCL1V2512-2R2M-R both have a maximum seated height of 0.047" (1.20mm). The BWVF002520122R2M00 has a maximum seated height of 0.049" (1.25mm), representing a 0.002" (0.05mm) difference. This minimal variation is typically acceptable for standard PCB assembly processes but should be verified against your board layout constraints.

Q: Do all parts have the same moisture sensitivity level?

A: Yes. All three parts—SWPA252012S2R2MT, BWVF002520122R2M00, and SDCL1V2512-2R2M-R—are rated at MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
