Substitute Part Grouping Explanation
Substitution eligibility for the ASPI-0704S-560M-T is determined by strict equivalence across the following critical parameters:
- Inductance value: 56 µH (exact match required)
- Inductance tolerance: ±20% (matching specification)
- Current rating: 750 mA minimum (equal or higher acceptable)
- DC resistance: 350mOhm maximum (equal or lower acceptable)
- Shielding: Shielded configuration (required for EMI performance)
- Core material: Ferrite (maintains frequency response characteristics)
- Mounting type: Surface mount (PCB assembly compatibility)
- Physical footprint: 7.30mm x 7.30mm base dimensions (board layout compatibility)
- Regulatory compliance: RoHS3 compliant (environmental and safety standards)
The CDRH74NP-560MC-B from Sumida America Components Inc. meets all substitution criteria within these parameters.

Engineering Selection Recommendations
Both the ASPI-0704S-560M-T and CDRH74NP-560MC-B maintain active product status with full RoHS3 compliance and REACH unaffected certification. Selection between these parts should be based on:
- Temperature environment: The ASPI-0704S-560M-T supports operation to 125°C, while the CDRH74NP-560MC-B is rated to 100°C maximum. Applications requiring sustained operation above 100°C require the Abracon part.
- Supply chain availability: The CDRH74NP-560MC-B currently has higher inventory (1853 pcs vs 932 pcs), which may influence lead time considerations.
- Packaging format: The ASPI-0704S-560M-T is supplied in standard packaging, while the CDRH74NP-560MC-B is supplied in Tape & Reel format, which may affect procurement and assembly processes.
Both parts are electrically and mechanically interchangeable for applications operating within the Sumida temperature range of -40°C to 100°C.
Frequently Asked Questions (FAQ)
Q: Can the CDRH74NP-560MC-B replace the ASPI-0704S-560M-T in all applications?
A: The CDRH74NP-560MC-B is a direct substitute for applications operating within -40°C to 100°C. Applications requiring operation above 100°C must use the ASPI-0704S-560M-T, which is rated to 125°C.
Q: Are the physical dimensions identical between these parts?
A: Yes. Both parts share identical base dimensions of 7.30mm x 7.30mm with a maximum seated height of 4.50mm, ensuring PCB layout compatibility and no design modifications are required.
Q: What is the significance of the ±20% inductance tolerance?
A: The ±20% tolerance indicates the acceptable range of inductance variation from the nominal 56 µH value. Both parts meet this specification, ensuring circuit performance consistency within design parameters.
Q: Does packaging format affect electrical performance?
A: No. The Tape & Reel packaging of the CDRH74NP-560MC-B is a supply and assembly format consideration only and does not affect electrical or mechanical performance compared to standard packaging.
Q: Are both parts compliant with current environmental regulations?
A: Yes. Both the ASPI-0704S-560M-T and CDRH74NP-560MC-B are ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards for electronic components.
Q: What is the maximum DC resistance specification for these inductors?
A: Both parts specify 350mOhm maximum DC resistance, which determines power dissipation and thermal characteristics at rated current.
