Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD54NP-120MC is determined by strict equivalence of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 12 µH with ±20% tolerance
• Current rating: 1.4 A minimum
• DC resistance: 120 mOhm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Surface Mount
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The SDR0604-120ML from Bourns Inc. meets all critical electrical specifications and mechanical requirements for direct substitution. Both parts maintain identical inductance, current rating, and DC resistance specifications. Physical dimensions remain within acceptable nonstandard package tolerances for surface mount applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CD54NP-120MC and SDR0604-120ML are Active status components with full RoHS3 compliance and MSL Level 1 rating. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical performance differences.

The CD54NP-120MC is manufactured by Sumida America Components Inc. and the SDR0604-120ML is manufactured by Bourns Inc. Both manufacturers maintain equivalent product certifications and regulatory compliance for this inductor category.

The SDR0604-120ML provides an extended operating temperature range to 125°C compared to the CD54NP-120MC at 100°C maximum. This extended range does not restrict substitution in applications operating within the CD54NP-120MC specification window.

Frequently Asked Questions (FAQ)

Q: Can the SDR0604-120ML replace the CD54NP-120MC in existing designs?

A: Yes. The SDR0604-120ML meets all electrical specifications including inductance value, current rating, and DC resistance. Physical dimensions are compatible with surface mount assembly processes for nonstandard packages.

Q: Are there differences in the core construction between these parts?

A: The CD54NP-120MC uses ferrite core construction. The SDR0604-120ML is specified as drum core wirewound with ferrite material. Both configurations deliver the specified 12 µH inductance and 120 mOhm DC resistance within the ±20% tolerance band.

Q: What is the significance of the extended temperature range on the SDR0604-120ML?

A: The SDR0604-120ML operates to 125°C maximum compared to 100°C for the CD54NP-120MC. This extended range provides additional thermal margin in applications but does not affect substitution compatibility for designs operating within the CD54NP-120MC temperature specification.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the CD54NP-120MC and SDR0604-120ML carry RoHS3 compliance certification and MSL Level 1 moisture sensitivity rating.

Q: What are the package considerations for substitution?

A: Both parts are specified as nonstandard surface mount packages with compatible physical dimensions. The CD54NP-120MC measures 5.80mm L x 5.20mm W x 4.85mm H. The SDR0604-120ML measures 5.80mm L x 5.80mm W x 4.80mm H. These dimensions are compatible with standard surface mount assembly equipment and PCB footprints designed for nonstandard inductor packages.
