Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD54NP-180MC is determined by strict equivalence across the following critical parameters:

Inductance Value: 18 µH nominal inductance is the primary electrical specification. Tolerance variations (±20% for CD54NP-180MC versus ±15% for SDR0604-180YL) remain within acceptable substitution limits when the nominal value matches exactly.

Current Rating: The substitute part must support the required current load. The CD54NP-180MC is rated for 1.23 A; the SDR0604-180YL is rated for 1.25 A, which exceeds the minimum requirement.

DC Resistance: Both parts specify 150mOhm maximum DC resistance, ensuring equivalent power dissipation characteristics.

Core Material and Shielding: Both parts utilize ferrite core construction with unshielded configuration, maintaining electromagnetic compatibility in the application circuit.

Mounting Type: Both parts are surface mount devices with nonstandard package dimensions compatible with the same PCB footprint requirements.

Environmental Compliance: Both parts carry ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring equivalent handling and storage requirements.

Parameter Comparison

Engineering Selection Recommendations

The SDR0604-180YL manufactured by Bourns Inc. is a direct substitute for the CD54NP-180MC. Both parts maintain Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating, ensuring equivalent supply chain reliability and regulatory compliance.

The substitute part provides equivalent or superior electrical performance: matching inductance at 18 µH, matching maximum DC resistance at 150mOhm, and exceeding the current rating requirement (1.25 A versus 1.23 A). The SDR0604-180YL offers tighter inductance tolerance (±15% versus ±20%) and an extended operating temperature range (-40°C to 125°C versus -40°C to 100°C).

Mechanical compatibility is maintained across height and length dimensions. The width dimension of the SDR0604-180YL (5.80mm) is 0.60mm greater than the CD54NP-180MC (5.20mm); PCB layout verification is required to confirm footprint accommodation.

Both parts are classified under HTSUS code 8504.50.4000 and carry EAR99 ECCN designation, maintaining equivalent export and regulatory classification.

Frequently Asked Questions (FAQ)

Q: Can the SDR0604-180YL replace the CD54NP-180MC in all applications?

A: The SDR0604-180YL is electrically and mechanically compatible as a substitute. The primary consideration is PCB footprint width: the Bourns part is 0.60mm wider (5.80mm versus 5.20mm). Verify available PCB space before substitution.

Q: What is the significance of the inductance tolerance difference?

A: The CD54NP-180MC specifies ±20% tolerance while the SDR0604-180YL specifies ±15% tolerance. The substitute part provides tighter tolerance control, which may improve circuit performance consistency but does not prevent substitution in applications designed for the wider tolerance.

Q: Are there temperature range implications for substitution?

A: The SDR0604-180YL operates to 125°C maximum versus 100°C for the CD54NP-180MC. This extended range does not create substitution restrictions; the substitute part remains functional across the original part's operating range.

Q: Do both parts require identical PCB layout considerations?

A: Both parts are surface mount unshielded ferrite inductors with equivalent electromagnetic characteristics. Layout considerations for unshielded inductors remain consistent between parts. The width dimension difference noted above is the primary layout consideration.

Q: Are packaging format differences significant?

A: The CD54NP-180MC is supplied in Tape & Reel (TR) format while the SDR0604-180YL is supplied in Cut Tape (CT) & Digi-Reel® format. Both are standard surface mount packaging formats; format selection depends on assembly process requirements rather than electrical compatibility.

Q: How do the Q factor specifications compare?

A: The SDR0604-180YL specifies Q @ 30 at 2.52 MHz. The CD54NP-180MC does not provide Q factor data. Both parts are tested at 2.52 MHz for inductance verification, ensuring measurement consistency.

Q: What is the saturation current consideration?

A: The SDR0604-180YL specifies saturation current (Isat) of 1.5 A. The CD54NP-180MC does not provide saturation current specification. The substitute part's saturation rating exceeds the maximum current requirement (1.23 A), confirming adequate margin.
