Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPM7054VT-150M-D is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 15 µH at 100 kHz test frequency
• Inductance tolerance: ±20%
• Shielding classification: Shielded construction
• Current rating: Minimum 4.5 A continuous
• Saturation current: Minimum 5 A
• DC resistance: Maximum 54.8 mOhm
• Operating temperature range: -55°C to 155°C minimum
• Mounting type: Surface Mount
• Compliance: AEC-Q200 rated, RoHS3 compliant

Mechanical Compatibility Parameters:

• Package footprint: Nonstandard form factor
• Height constraint: Maximum 5.40 mm seated height
• Packaging format: Tape & Reel (TR)

The HCM1A0805V2-150-R meets these substitution criteria through equivalent inductance, matching tolerance, shielded construction, compatible current ratings within specification, and identical compliance certifications. Dimensional differences in length and width (8.10 × 8.00 mm versus 7.50 × 7.00 mm) require PCB layout verification for footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The SPM7054VT-150M-D remains the preferred component when design specifications require the exact current rating of 4.5 A and saturation current of 5 A. This part carries Active product status with confirmed inventory of 1568 pieces and maintains full AEC-Q200 automotive qualification with RoHS3 compliance.

Substitute Part Selection: The HCM1A0805V2-150-R (Eaton - Electronics Division) qualifies as an electrical and compliance equivalent when application current requirements do not exceed 4 A continuous operation and saturation margin requirements permit 4.6 A operation. This substitute maintains identical inductance value, tolerance, shielding classification, and temperature operating range. Both parts carry AEC-Q200 rating and RoHS3 compliance certification, ensuring equivalent reliability and regulatory standing.

Mechanical Compatibility Consideration: The substitute part features a larger footprint (8.10 × 8.00 mm versus 7.50 × 7.00 mm). PCB layout verification is required to confirm pad spacing and component placement compatibility before design implementation. Both parts maintain identical 5.40 mm maximum seated height.

Compliance and Regulatory Status: Both parts are REACH Unaffected, classified under ECCN EAR99, and carry identical HTSUS code 8504.50.8000. Moisture sensitivity level 1 (Unlimited) applies to both components, eliminating special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the HCM1A0805V2-150-R directly replace the SPM7054VT-150M-D in all applications?

A: Electrical substitution is valid when application current requirements do not exceed 4 A continuous and 4.6 A saturation limits. Mechanical substitution requires PCB layout verification due to larger footprint dimensions (8.10 × 8.00 mm versus 7.50 × 7.00 mm). Both parts maintain identical height and comply with AEC-Q200 and RoHS3 standards.

Q: What are the key electrical differences between these parts?

A: Both parts provide 15 µH inductance at ±20% tolerance with shielded construction. The SPM7054VT-150M-D is rated for 4.5 A continuous current with 5 A saturation, while the HCM1A0805V2-150-R is rated for 4 A continuous with 4.6 A saturation. DC resistance is 54.8 mOhm for the TDK part and 52 mOhm maximum for the Eaton part. Operating temperature range is identical at -55°C to 155°C.

Q: Are there compliance or certification differences?

A: No. Both parts carry AEC-Q200 automotive qualification, RoHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating. Regulatory classification and HTSUS coding are identical.

Q: What is the impact of the larger footprint on PCB design?

A: The substitute part measures 8.10 × 8.00 mm compared to 7.50 × 7.00 mm for the original. Pad spacing, trace routing, and component placement must be verified against the specific PCB layout. Height remains constant at 5.40 mm maximum seated height for both parts.

Q: Which part should be selected for new designs?

A: For new designs with current requirements at or below 4 A, either part is acceptable provided PCB layout accommodates the larger footprint of the substitute. For designs requiring the full 4.5 A rating or 5 A saturation margin, the SPM7054VT-150M-D is the appropriate selection.

Q: Is the self-resonant frequency specification important for substitution?

A: The SPM7054VT-150M-D does not specify self-resonant frequency. The HCM1A0805V2-150-R specifies 8 MHz. Application-specific frequency response requirements should be evaluated independently for each design to determine if this parameter affects component selection.
