Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDRR75NP-470MC is determined by the following critical parameters:

Primary Electrical Criteria:

• Inductance value: 47 µH (±20% tolerance band)
• Current rating: minimum 1.08 A continuous
• DC resistance: maximum 190mOhm
• Saturation current: minimum 600mA
• Core material: Ferrite
• Shielding: Shielded configuration

Mechanical & Environmental Criteria:

• Mounting type: Surface Mount
• Operating temperature range: must encompass -40°C to 125°C minimum
• Moisture sensitivity: MSL 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

Package Considerations:

• Nonstandard package classification
• Physical dimensions must accommodate board layout constraints
• Height seated maximum: 0.189" (4.80mm) reference

All three substitute parts meet or exceed the primary electrical specifications while maintaining ferrite core shielded construction and surface mount compatibility.

Engineering Selection Recommendations

B82472P6473M000 (EPCOS - TDK Electronics)

This substitute provides extended operating temperature range (-55°C to 150°C) and higher saturation current (900mA) compared to the main part. DC resistance specification of 200mOhm is within acceptable tolerance relative to the 190mOhm maximum of the CDRR75NP-470MC. The part carries AEC-Q200 automotive qualification, indicating enhanced reliability screening. ROHS3 compliance and MSL 1 rating match the main part requirements. Current rating of 1 A is below the main part specification of 1.08 A; this represents a constraint for applications requiring the full 1.08 A continuous current.

CLF7045T-470M-D (TDK Corporation)

This substitute exceeds the main part specifications in current rating (1.2 A versus 1.08 A) and saturation current (1.3 A versus 600mA). DC resistance of 180mOhm is superior to the 190mOhm maximum specification. Operating temperature range extends to 150°C maximum, providing margin above the -40°C to 125°C requirement. AEC-Q200 qualification is present. ROHS3 compliance and MSL 1 rating are maintained. Packaging is specified as Cut Tape (CT) & Digi-Reel® rather than Tape & Reel (TR), which may affect procurement and handling procedures.

DR74-470-R (Eaton - Electronics Division)

This substitute provides current rating of 1.15 A, exceeding the main part specification of 1.08 A, with saturation current of 1.41 A. DC resistance of 216mOhm exceeds the 190mOhm maximum specification of the main part by 26mOhm, representing a measurable increase in power dissipation. Operating temperature range matches the main part at -40°C to 125°C. ROHS3 compliance and MSL 1 rating are maintained. No AEC-Q200 qualification is listed for this part.

All three substitutes maintain ferrite core shielded construction, surface mount configuration, and nonstandard package classification. Selection should be based on specific application requirements regarding current capacity, thermal performance, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the B82472P6473M000 be used as a direct replacement for the CDRR75NP-470MC?

A: The B82472P6473M000 meets most electrical and environmental specifications. However, its current rating of 1 A is below the main part specification of 1.08 A. Direct substitution is permissible only in applications where continuous current does not exceed 1 A. The extended temperature range (-55°C to 150°C) and higher saturation current (900mA) provide additional design margin in other respects.

Q: What is the significance of the DC resistance difference between these parts?

A: DC resistance directly affects power dissipation in the inductor. The CDRR75NP-470MC specifies 190mOhm maximum. The CLF7045T-470M-D at 180mOhm provides lower dissipation. The DR74-470-R at 216mOhm results in approximately 13.7% higher dissipation at rated current. For thermal-sensitive applications, the CLF7045T-470M-D offers superior performance; the DR74-470-R requires thermal evaluation.

Q: Are all substitute parts qualified to the same automotive standards?

A: The B82472P6473M000 and CLF7045T-470M-D both carry AEC-Q200 qualification. The DR74-470-R does not list AEC-Q200 qualification in the provided specifications. For automotive applications requiring AEC-Q200 compliance, the B82472P6473M000 and CLF7045T-470M-D are appropriate selections.

Q: How do packaging differences affect component selection?

A: The CDRR75NP-470MC and B82472P6473M000 are supplied in Tape & Reel (TR) format. The CLF7045T-470M-D is supplied in Cut Tape (CT) & Digi-Reel® format. Tape & Reel packaging is standard for high-volume automated assembly. Cut Tape format requires different handling and may incur additional processing costs. Physical dimensions vary slightly: CDRR75NP-470MC is 6.90mm x 6.90mm; B82472P6473M000 is 7.30mm x 7.30mm; CLF7045T-470M-D is 7.20mm x 6.90mm; DR74-470-R is 7.60mm x 7.60mm. Board layout constraints must accommodate these dimensional variations.

Q: What is the inductance tolerance band for these parts?

A: All parts, including the main part and all substitutes, specify ±20% inductance tolerance at 100 kHz test frequency. This means the actual inductance value can range from 37.6 µH to 56.4 µH. Circuit designs must account for this tolerance band in performance calculations.

Q: Can saturation current differences affect circuit performance?

A: Saturation current (Isat) defines the current level at which the inductor's inductance begins to degrade significantly. The CDRR75NP-470MC specifies 600mA Isat. The substitutes provide higher saturation currents: B82472P6473M000 at 900mA, CLF7045T-470M-D at 1.3 A, and DR74-470-R at 1.41 A. Higher saturation current provides greater margin before inductance degradation occurs, beneficial for applications with current transients or ripple.

Q: Are all parts RoHS3 compliant?

A: Yes. The CDRR75NP-470MC and all three substitute parts are ROHS3 compliant. All parts also carry MSL 1 (Unlimited) moisture sensitivity level rating, indicating no moisture sensitivity constraints during storage or handling.
