Substitute Part Grouping Explanation
Substitution eligibility for the SPM7054VT-220M-D is determined by the following critical parameters:
Electrical Equivalence Criteria:
- Inductance value of 22 µH within ±20% tolerance
- Current rating minimum of 3.9 A continuous
- Saturation current (Isat) minimum of 4.2 A
- DC resistance not exceeding 71.9 mOhm
- Shielded construction to maintain electromagnetic isolation
- Operating temperature range of -55°C to 155°C minimum
Mechanical Compatibility Criteria:
- Surface mount configuration
- Package dimensions compatible with 7.50 × 7.00 mm footprint tolerance
- Height (seated) maximum of 5.40 mm
- AEC-Q200 automotive qualification
- ROHS3 compliance
The substitute part HCM1A0805V2-220-R meets these criteria with equivalent inductance, comparable current handling, and compatible thermal and compliance specifications.

Engineering Selection Recommendations
Both the SPM7054VT-220M-D and HCM1A0805V2-220-R maintain Active product status with full AEC-Q200 automotive qualification and ROHS3 compliance, making them suitable for regulated applications.
The primary selection considerations are:
SPM7054VT-220M-D (TDK): Higher current rating (3.9 A) and saturation current (4.2 A) provide greater design margin for applications operating near maximum current specifications. Smaller package footprint (7.50 × 7.00 mm) accommodates space-constrained PCB layouts.
HCM1A0805V2-220-R (Eaton): Lower current ratings (4.6 A continuous, 4.0 A saturation) require verification that application current demands remain within specified limits. Larger package footprint (8.10 × 8.00 mm) necessitates PCB layout review for compatibility. DC resistance specification of 70 mOhm maximum provides equivalent thermal performance.
Selection between these parts depends on application current requirements and available PCB real estate. Both parts satisfy identical compliance and temperature operating specifications.
Frequently Asked Questions (FAQ)
Q: Can HCM1A0805V2-220-R replace SPM7054VT-220M-D in all applications?
A: Substitution is valid only when application current remains below 4.6 A continuous and 4.0 A saturation limits. Applications requiring the full 3.9 A rating of the original part require the SPM7054VT-220M-D.
Q: What is the impact of the larger package size of the HCM1A0805V2-220-R?
A: The substitute part measures 8.10 × 8.00 mm compared to the original 7.50 × 7.00 mm. PCB layout must be reviewed to confirm adequate clearance and trace routing compatibility. Both parts maintain identical 5.40 mm seated height.
Q: Are both parts qualified for automotive applications?
A: Yes. Both SPM7054VT-220M-D and HCM1A0805V2-220-R carry AEC-Q200 certification and are suitable for automotive-grade applications.
Q: How do the DC resistance values compare?
A: The original part specifies 71.9 mOhm while the substitute specifies 70 mOhm maximum. This represents equivalent thermal performance with negligible difference in power dissipation across the specified current range.
Q: What is the inductance tolerance for both parts?
A: Both parts maintain ±20% inductance tolerance at 100 kHz test frequency, ensuring equivalent circuit performance within specified tolerance bands.
Q: Are both parts ROHS3 compliant?
A: Yes. Both SPM7054VT-220M-D and HCM1A0805V2-220-R are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
