Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0704S-180M-T is determined by strict alignment of the following parameters:

• Inductance value: 18 µH with ±20% tolerance
• Current rating: 1.31 A minimum
• DC resistance: 91 mOhm maximum
• Shielding: Shielded configuration required
• Core material: Ferrite
• Package dimensions: 7.30 mm L × 7.30 mm W × 4.50 mm H (maximum seated height)
• Mounting: Surface mount, tape and reel packaging
• Compliance: ROHS3 compliant, MSL 1

The CDRH74NP-180MC-B from Sumida America Components Inc. meets all critical electrical and mechanical parameters. Both components share identical inductance, current rating, DC resistance specification, shielding type, core material, and physical dimensions. Compliance certifications align for both parts under ROHS3 and MSL 1 standards.

Parameter Comparison

Engineering Selection Recommendations

Both ASPI-0704S-180M-T and CDRH74NP-180MC-B maintain Active product status with full ROHS3 compliance and MSL 1 certification, supporting long-term availability and regulatory requirements. The components are electrically and mechanically interchangeable for applications operating within the overlapping temperature range of -40°C to 100°C. For applications requiring operation above 100°C up to 125°C, the ASPI-0704S-180M-T provides extended thermal capability. Both parts are supplied in tape and reel packaging suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CDRH74NP-180MC-B replace ASPI-0704S-180M-T in all applications?

A: Yes, for applications operating within -40°C to 100°C. The substitute part meets all electrical specifications (18 µH inductance, 1.31 A current rating, 91 mOhm DC resistance) and physical dimensions. Applications requiring sustained operation above 100°C should use the original ASPI-0704S-180M-T, which is rated to 125°C.

Q: Are the package dimensions identical?

A: Yes. Both components measure 7.30 mm × 7.30 mm × 4.50 mm (maximum seated height) and use identical surface mount footprints. PCB layout and assembly processes require no modification.

Q: What is the significance of the ±20% inductance tolerance?

A: The ±20% tolerance defines the acceptable inductance range (14.4 µH to 21.6 µH) for both parts. This tolerance applies equally to both the original and substitute component, ensuring equivalent circuit performance within specified limits.

Q: Do both parts require the same handling and storage conditions?

A: Yes. Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard ESD precautions and room-temperature storage apply to both parts.

Q: Is the DC resistance specification identical?

A: The ASPI-0704S-180M-T specifies 91 mOhm, while CDRH74NP-180MC-B specifies 91 mOhm Max. The substitute part's maximum specification aligns with the original part's nominal value, ensuring compatible power dissipation characteristics.
