Substitute Part Grouping Explanation

Substitution eligibility for the SPM10054T-150M-HZ is determined by the following critical parameters:

• Inductance value: 15 µH (exact match required)
• Tolerance: ±20% (must be maintained)
• Shielding: Shielded configuration (electromagnetic containment requirement)
• Operating temperature range: -40°C ~ 125°C (environmental compatibility)
• Mounting type: Surface Mount (assembly process compatibility)
• Physical dimensions: 0.421" L x 0.394" W x 0.213" H max (PCB layout constraint)
• AEC-Q200 certification: Required for automotive applications
• RoHS3 compliance: Regulatory requirement

The SPM10054T-150M-HZR qualifies as a substitute based on matching inductance, tolerance, shielding, temperature range, mounting type, physical dimensions, and certifications. Variations in current rating, saturation current, and DC resistance are acceptable within the electrical design parameters of the application circuit.

Parameter Comparison

Engineering Selection Recommendations

The SPM10054T-150M-HZR is the manufacturer-recommended substitute for the SPM10054T-150M-HZ. Both components maintain identical inductance values, tolerance specifications, shielding configurations, and physical dimensions required for direct PCB compatibility. Both are AEC-Q200 certified and ROHS3 compliant, meeting automotive and regulatory requirements.

The primary distinction is product status: the original SPM10054T-150M-HZ is classified as Not For New Designs, while the SPM10054T-150M-HZR is Active. For new design initiatives and ongoing production, the SPM10054T-150M-HZR is the appropriate selection. The SPM10054T-150M-HZ remains suitable for legacy system support and maintenance applications where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Can the SPM10054T-150M-HZR directly replace the SPM10054T-150M-HZ on existing PCBs?

A: Yes. Both components share identical physical dimensions (0.421" L x 0.394" W x 0.213" H max), nonstandard package configuration, and surface mount mounting type. PCB layout and footprint compatibility are maintained.

Q: What are the differences in electrical performance between these two parts?

A: The SPM10054T-150M-HZR has a lower continuous current rating (5.7 A versus 8.6 A) and slightly higher maximum DC resistance (38.2 mOhm versus 33.93 mOhm). The saturation current (Isat) is higher in the substitute (5.1 A versus 3.6 A). These differences must be evaluated against the specific application circuit requirements.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the SPM10054T-150M-HZ and SPM10054T-150M-HZR are AEC-Q200 certified, meeting automotive qualification standards. Both operate across the -40°C ~ 125°C temperature range required for automotive environments.

Q: Why is the original part marked as Not For New Designs?

A: The SPM10054T-150M-HZ is a legacy component. TDK Corporation has transitioned to the SPM10054T-150M-HZR as the active equivalent. New designs should specify the active substitute to ensure long-term supply chain availability and manufacturer support.

Q: Are there any compliance or regulatory differences?

A: No. Both components are ROHS3 compliant, REACH unaffected, and classified under the same ECCN (EAR99) and HTSUS (8504.50.4000) codes. Regulatory and environmental compliance requirements are identical.
