Key Parameters

Substitute Part Grouping Explanation

The SDR0604-150YL from Bourns Inc. qualifies as a direct substitute for the CD54NP-150MC based on the following critical parameters:

Matching Electrical Specifications:

• Inductance: 15 µH (identical)
• Current Rating: 1.3 A (identical)
• DC Resistance: 140 mOhm Max (identical)
• Shielding: Unshielded (identical)
• Core Material: Ferrite (identical)

Matching Mechanical Specifications:

• Mounting Type: Surface Mount (identical)
• Package Classification: Nonstandard (identical)
• Physical Dimensions: 0.228" L x 0.228" W (5.80mm x 5.80mm) for SDR0604-150YL vs. 0.228" L x 0.205" W (5.80mm x 5.20mm) for CD54NP-150MC (compatible within nonstandard package tolerance)
• Height - Seated (Max): 0.189" (4.80mm) for SDR0604-150YL vs. 0.191" (4.85mm) for CD54NP-150MC (compatible)

Compliance Alignment:

• RoHS Status: ROHS3 Compliant (both parts)
• Moisture Sensitivity Level: 1 (Unlimited) (both parts)
• ECCN Classification: EAR99 (both parts)

The SDR0604-150YL exhibits a tighter inductance tolerance (±15% vs. ±20%) and an extended operating temperature range (-40°C to 125°C vs. -40°C to 100°C), providing additional design margin in thermal applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CD54NP-150MC and SDR0604-150YL are Active status components with full RoHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is determined by application-specific requirements:

CD54NP-150MC Selection Criteria:

• Applications requiring the exact physical footprint of 0.228" L x 0.205" W
• Designs with strict height constraints at 0.191" maximum seated height
• Operating environments limited to -40°C to 100°C temperature range
• Tape & Reel packaging preference

SDR0604-150YL Selection Criteria:

• Applications benefiting from tighter inductance tolerance (±15% vs. ±20%)
• Designs requiring extended thermal operation to 125°C
• Saturation current specification requirement (1.6 A available)
• Q factor specification requirement (30 @ 2.52 MHz available)
• Cut Tape & Digi-Reel® packaging preference
• Slightly wider footprint tolerance (0.228" W vs. 0.205" W)

Both parts maintain identical electrical performance at rated current (1.3 A) and DC resistance (140 mOhm maximum). The SDR0604-150YL provides additional design margin through extended temperature range and improved inductance tolerance.

Frequently Asked Questions (FAQ)

Q: Can the SDR0604-150YL directly replace the CD54NP-150MC in existing PCB layouts?

A: Physical compatibility depends on PCB pad spacing and height clearance. The SDR0604-150YL is 0.023" wider (5.80mm vs. 5.20mm) and 0.002" shorter in seated height (4.80mm vs. 4.85mm). Verify pad-to-pad distance and vertical clearance before substitution.

Q: What is the significance of the inductance tolerance difference (±20% vs. ±15%)?

A: The SDR0604-150YL tolerance of ±15% provides tighter inductance control compared to the CD54NP-150MC at ±20%. This reduces circuit performance variation in applications sensitive to inductance value, such as resonant circuits or impedance matching networks.

Q: Are both parts suitable for high-temperature applications?

A: The CD54NP-150MC operates to 100°C maximum, while the SDR0604-150YL extends to 125°C. For applications approaching or exceeding 100°C ambient or junction temperature, the SDR0604-150YL provides additional thermal margin.

Q: What packaging formats are available for each part?

A: The CD54NP-150MC is supplied in Tape & Reel (TR) format. The SDR0604-150YL is supplied in Cut Tape (CT) & Digi-Reel® format. Verify packaging compatibility with assembly equipment and procurement workflows.

Q: Do both parts meet the same regulatory compliance standards?

A: Both the CD54NP-150MC and SDR0604-150YL are ROHS3 compliant, classified as EAR99 for export control, and carry MSL 1 (Unlimited) moisture sensitivity rating. No compliance differences exist between the two parts.

Q: Is saturation current a critical parameter for this substitution?

A: The SDR0604-150YL specifies saturation current at 1.6 A, while the CD54NP-150MC does not provide this specification. For applications operating near or above 1.3 A rated current, the SDR0604-150YL saturation specification provides additional design information but does not affect substitution validity at the 1.3 A rating.
