Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0704S-471M-T is determined by strict equivalence across the following critical parameters:

• Inductance value: 470 µH with ±20% tolerance
• Current rating: 260 mA minimum continuous current capability
• Core type: Ferrite material with shielding
• Mounting configuration: Surface mount package
• Physical footprint: 7.30 x 7.30 mm base dimensions
• Compliance: ROHS3 and moisture sensitivity level 1 (unlimited)

The identified substitute parts maintain these core electrical and mechanical specifications, enabling direct functional replacement in circuit applications designed for the ASPI-0704S-471M-T.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status with ROHS3 compliance and unlimited moisture sensitivity rating, confirming their suitability for equivalent application use.

B82472G4474M000 (EPCOS - TDK Electronics): This substitute offers improved DC resistance performance at 2.7 Ohm maximum, lower than the 3.01 Ohm specification of the primary part. The extended operating temperature range of -55°C to 125°C provides broader thermal coverage. Height is reduced to 4.60 mm, offering potential PCB layout advantages. Current saturation specification of 240 mA is provided. Packaging is Tape & Reel format with higher inventory availability (2629 pieces).

CDRH74NP-471MC-B (Sumida America Components Inc.): This substitute maintains identical DC resistance specification of 3.01 Ohm and matching height of 4.50 mm. Operating temperature range is -40°C to 100°C, with the upper limit 25°C lower than the primary part. Inductance frequency test is performed at 1 kHz versus 100 kHz for the primary part. Packaging is Tape & Reel format with highest inventory availability (9965 pieces).

Frequently Asked Questions (FAQ)

Q: Can B82472G4474M000 be used as a direct replacement for ASPI-0704S-471M-T?

A: Yes. Both parts share identical inductance (470 µH), current rating (260 mA), core material (ferrite), shielding, mounting type (surface mount), and physical footprint (7.30 x 7.30 mm). The lower DC resistance of B82472G4474M000 (2.7 Ohm vs. 3.01 Ohm) is within acceptable substitution parameters. The reduced height (4.60 mm vs. 4.50 mm) may require PCB layout verification for clearance compatibility.

Q: Can CDRH74NP-471MC-B be used as a direct replacement for ASPI-0704S-471M-T?

A: Yes. Both parts share identical inductance (470 µH), current rating (260 mA), DC resistance (3.01 Ohm max), core material (ferrite), shielding, mounting type (surface mount), physical footprint (7.30 x 7.30 mm), and height (4.50 mm). The operating temperature upper limit of 100°C is 25°C lower than the primary part; applications operating above 100°C require thermal performance verification.

Q: What are the key differences between the substitute parts?

A: B82472G4474M000 features lower DC resistance (2.7 Ohm), extended low-temperature rating (-55°C), and reduced height (4.60 mm). CDRH74NP-471MC-B maintains identical DC resistance and height specifications but has a lower upper operating temperature limit (100°C). Both are ROHS3 compliant with unlimited moisture sensitivity.

Q: Are all parts available in the same packaging format?

A: The primary part ASPI-0704S-471M-T packaging format is not specified in the data. Both substitute parts B82472G4474M000 and CDRH74NP-471MC-B are supplied in Tape & Reel (TR) format, which is standard for surface mount inductors in production environments.

Q: What compliance certifications apply to all three parts?

A: All three parts are ROHS3 compliant, carry moisture sensitivity level 1 (unlimited), and are classified under ECCN EAR99. REACH status is unaffected for ASPI-0704S-471M-T and B82472G4474M000; CDRH74NP-471MC-B shows vendor undefined REACH status.
