Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SWPA3015S100MT is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 10 µH with ±20% tolerance
• Inductance test frequency: 100 kHz
• Core material: Ferrite
• Mounting type: Surface Mount
• Package footprint: 3.00mm x 3.00mm x 1.50mm maximum height
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Criteria:

• Current rating: minimum 770 mA continuous
• DC resistance: maximum 325 mOhm
• Operating temperature range: minimum -40°C to 125°C overlap
• Shielding: Shielded or Semi-Shielded configuration

Substitute parts must satisfy all primary matching criteria and maintain electrical performance within the secondary compatibility parameters. Parts meeting these specifications are electrically and mechanically interchangeable in applications designed for the SWPA3015S100MT.

Parameter Comparison

Engineering Selection Recommendations

BWVF00303015100M00 (Pulse Electronics): This substitute provides the highest current rating at 1 A with saturation current of 1.06 A, exceeding the SWPA3015S100MT specification. DC resistance is 360 mOhm, within acceptable tolerance. The part is fully shielded and RoHS3 compliant with REACH unaffected status. Operating temperature range extends to -55°C, providing enhanced low-temperature performance. Inductance test frequency differs at 1 MHz versus 100 kHz for the main part. This substitute is suitable for applications requiring higher current headroom or extended low-temperature operation.

SDCL1V3015-100M-R (Eaton - Electronics Division): This substitute operates at 700 mA continuous current with 780 mA saturation, slightly below the SWPA3015S100MT rating. DC resistance is 311 mOhm Max, the lowest among all options, providing superior thermal performance. The part features semi-shielded configuration versus full shielding on the main part. Operating temperature range matches the main part at -40°C to 125°C. Inductance test frequency aligns at 100 kHz. RoHS compliant with REACH unaffected status. This substitute is optimal for applications prioritizing low DC resistance and thermal efficiency where semi-shielded performance is acceptable.

All three parts share identical inductance values, tolerance, package footprint, and moisture sensitivity classification. Product status is active for all options, ensuring continued availability.

Frequently Asked Questions (FAQ)

Q: Can BWVF00303015100M00 directly replace SWPA3015S100MT in all applications?

A: BWVF00303015100M00 is electrically compatible as a direct substitute. It maintains the same 10 µH inductance, ±20% tolerance, and identical package footprint. The higher current rating (1 A versus 770 mA) and lower saturation current (1.06 A versus 920 mA) provide additional design margin. The primary difference is inductance test frequency (1 MHz versus 100 kHz), which may affect measured inductance values in specific circuit conditions. Verify application requirements before substitution.

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

A: DC resistance directly impacts power dissipation and thermal performance. SDCL1V3015-100M-R exhibits the lowest DCR at 311 mOhm Max, resulting in reduced I²R losses. SWPA3015S100MT specifies 325 mOhm Max, and BWVF00303015100M00 is rated at 360 mOhm. In high-current applications, the 49 mOhm difference between SDCL1V3015-100M-R and BWVF00303015100M00 produces measurable thermal variation. Select based on thermal budget requirements.

Q: Are there packaging format differences that affect assembly?

A: Yes. SWPA3015S100MT and BWVF00303015100M00 are supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly. SDCL1V3015-100M-R is supplied in Cut Tape (CT) format, requiring manual handling or alternative feeder systems. Verify assembly equipment compatibility before selecting the Cut Tape option.

Q: How do shielding differences affect circuit performance?

A: SWPA3015S100MT and BWVF00303015100M00 are fully shielded, providing maximum electromagnetic interference (EMI) containment. SDCL1V3015-100M-R is semi-shielded, offering reduced EMI suppression. In noise-sensitive applications, fully shielded parts are preferred. Semi-shielded parts are acceptable in applications with lower EMI requirements or where thermal performance takes priority.

Q: What is the impact of different inductance test frequencies?

A: Inductance values are measured at specific frequencies: SWPA3015S100MT and SDCL1V3015-100M-R at 100 kHz, and BWVF00303015100M00 at 1 MHz. Inductance exhibits frequency-dependent behavior; values measured at different frequencies may vary. For applications operating near 100 kHz, parts tested at 100 kHz provide more accurate performance prediction. For higher-frequency applications, the 1 MHz test frequency of BWVF00303015100M00 is more representative.

Q: Are all three parts RoHS and REACH compliant?

A: BWVF00303015100M00 is explicitly RoHS3 compliant with REACH unaffected status. SDCL1V3015-100M-R is RoHS compliant with REACH unaffected status. SWPA3015S100MT compliance documentation is not provided in the specification. Verify RoHS and REACH status with the supplier for the main part if regulatory compliance is required.

Q: What current rating should be selected for my application?

A: Select based on continuous operating current requirements. SWPA3015S100MT is rated for 770 mA continuous. BWVF00303015100M00 supports 1 A continuous, providing 230 mA additional margin. SDCL1V3015-100M-R is rated for 700 mA continuous, 70 mA below the main part. For applications operating at or near 770 mA, BWVF00303015100M00 provides the highest safety margin. For applications below 700 mA, all three parts are suitable.
