Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPM10040T-220M-HZ is determined by the following critical parameters:

• Inductance value: 22 µH (exact match required)
• Inductance tolerance: ±20% (must be maintained)
• Shielding type: Shielded (electromagnetic containment requirement)
• Core material: Metal (performance characteristic)
• Operating temperature range: -40°C to 125°C (minimum requirement)
• Package dimensions: 10.70 mm L × 10.00 mm W × 4.00 mm H maximum (physical fit)
• AEC-Q200 qualification: Required for automotive applications
• RoHS3 compliance: Required for regulatory conformance
• Mounting type: Surface mount (assembly compatibility)

The SPM10040T-220M-HZR qualifies as a direct substitute based on matching all critical parameters. While the current rating and saturation current specifications differ between the main part and substitute, both components maintain the same inductance, tolerance, shielding, core material, temperature range, package dimensions, and automotive qualifications.

Engineering Selection Recommendations

The SPM10040T-220M-HZR is the qualified substitute for the SPM10040T-220M-HZ. Selection between these parts should be based on the following criteria:

For applications where the original SPM10040T-220M-HZ is currently in use, transition to SPM10040T-220M-HZR is supported by matching inductance, tolerance, shielding, core material, temperature range, package dimensions, and automotive qualifications. The SPM10040T-220M-HZR carries Active product status, ensuring long-term availability and supply chain continuity.

Current rating differences (5.2 A versus 3.8 A continuous) and saturation current differences (3.4 A versus 4.6 A) must be evaluated against specific circuit requirements. DC resistance values are equivalent within engineering tolerance (78.94 mOhm versus 79 mOhm).

Both components maintain AEC-Q200 automotive qualification and ROHS3 compliance, supporting use in regulated automotive and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can SPM10040T-220M-HZR be used as a direct replacement for SPM10040T-220M-HZ?

A: Yes, SPM10040T-220M-HZR qualifies as a direct substitute. Both components share identical inductance (22 µH), tolerance (±20%), shielding type, core material, operating temperature range (-40°C to 125°C), package dimensions (10.70 mm × 10.00 mm × 4.00 mm), AEC-Q200 rating, and RoHS3 compliance. Current rating and saturation current specifications differ and must be evaluated against circuit requirements.

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

A: The primary differences are continuous current rating (5.2 A versus 3.8 A) and saturation current (3.4 A versus 4.6 A). DC resistance is equivalent (78.94 mOhm versus 79 mOhm). Product status differs, with SPM10040T-220M-HZ marked "Not For New Designs" and SPM10040T-220M-HZR marked "Active."

Q: Are the package dimensions identical?

A: Yes. Both components use identical surface mount package dimensions of 10.70 mm length × 10.00 mm width × 4.00 mm maximum height, ensuring mechanical compatibility in existing PCB layouts.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both SPM10040T-220M-HZ and SPM10040T-220M-HZR carry AEC-Q200 qualification and ROHS3 compliance, supporting automotive and industrial applications.

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

A: Parts designated "Not For New Designs" indicate that the manufacturer is transitioning away from that product line. SPM10040T-220M-HZR represents the active equivalent for new designs and ongoing production.
