Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDRR75NP-221MC is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Inductance value: 220 µH (within ±20% tolerance band)
• Inductance tolerance: ±20%
• Core material: Ferrite shielded construction
• Mounting type: Surface Mount
• Operating temperature range: Minimum -40°C to 125°C coverage
• Package dimensions: Compatible with 6.90mm × 6.90mm footprint

Secondary Compatibility Parameters:

• Current rating: Minimum 520 mA (acceptable reduction from 540 mA within design margin)
• DC resistance: Maximum 792 mOhm (acceptable increase from 721 mOhm within thermal budget)
• Saturation current: Minimum 290 mA
• RoHS3 compliance required
• Moisture sensitivity level: 1 (Unlimited)

The substitute parts CLF7045T-221M-D, LGJ7045TC-221M-D, and LGJ7045TC-221M-H meet these criteria through equivalent inductance specifications, compatible physical dimensions, and ferrite shielded core construction. All substitutes maintain surface mount compatibility and RoHS3 compliance.

Engineering Selection Recommendations

CLF7045T-221M-D (Primary Substitute)

The CLF7045T-221M-D from TDK Corporation is the preferred substitute for the CDRR75NP-221MC. This part maintains Active product status, ensuring long-term availability and supply chain stability. The CLF7045T-221M-D provides an extended operating temperature range (-40°C to 150°C) compared to the main part, offering additional thermal margin. DC resistance increases to 792 mOhm (maximum), which remains within acceptable design tolerance for most applications. Current rating of 520 mA represents a 3.7% reduction from the main part specification, acceptable for designs with adequate current margin. The part is supplied in standard Tape & Reel packaging and carries AEC-Q200 automotive qualification, indicating enhanced reliability documentation.

LGJ7045TC-221M-D and LGJ7045TC-221M-H (Secondary Substitutes)

Both LGJ7045TC variants from TDK Corporation are classified as Obsolete, indicating discontinued production status. These parts should be selected only when supply of the primary substitute is unavailable and existing inventory is confirmed. The LGJ7045TC-221M-D offers superior DC resistance at 660 mOhm (maximum), providing lower losses than both the main part and primary substitute. The LGJ7045TC-221M-H maintains identical electrical specifications but is limited to -40°C to 125°C operating range, matching the main part temperature specification. Both variants are supplied in Cut Tape and Digi-Reel® packaging formats. AEC-Q200 qualification is present on both parts.

Selection Priority:

1. CLF7045T-221M-D (Active status, extended temperature range, standard packaging)
2. LGJ7045TC-221M-D (Obsolete, lower DCR, alternative packaging)
3. LGJ7045TC-221M-H (Obsolete, lower DCR, matching temperature range)

Frequently Asked Questions (FAQ)

Q: Can CLF7045T-221M-D be used as a direct replacement for CDRR75NP-221MC?

A: Yes. Both parts share identical inductance (220 µH), tolerance (±20%), core material (ferrite shielded), and mounting type (surface mount). The CLF7045T-221M-D operates across -40°C to 150°C, covering the main part's -40°C to 125°C range. Current rating of 520 mA is 20 mA lower than the main part's 540 mA specification. DC resistance increases from 721 mOhm to 792 mOhm maximum. These differences are within acceptable engineering margins for most applications.

Q: What is the difference between CLF7045T-221M-D and the LGJ7045TC variants?

A: CLF7045T-221M-D maintains Active product status with ongoing manufacturer support and standard Tape & Reel packaging. Both LGJ7045TC variants are Obsolete, indicating discontinued production. The LGJ7045TC-221M-D and LGJ7045TC-221M-H offer lower DC resistance (660 mOhm) compared to CLF7045T-221M-D (792 mOhm), reducing power dissipation. LGJ variants are supplied in Cut Tape and Digi-Reel® packaging. For new designs, CLF7045T-221M-D is recommended due to Active status.

Q: Are there package dimension differences between the main part and substitutes?

A: Yes. The CDRR75NP-221MC measures 6.90mm × 6.90mm × 4.80mm (L × W × H). All TDK substitutes measure 7.20mm × 6.90mm in length and width, representing a 0.30mm increase in length. CLF7045T-221M-D maintains 4.80mm height, while both LGJ7045TC variants are 4.50mm tall. These dimensional differences require PCB layout verification to confirm footprint compatibility.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. The CDRR75NP-221MC and all three substitute parts (CLF7045T-221M-D, LGJ7045TC-221M-D, LGJ7045TC-221M-H) are ROHS3 Compliant. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during assembly.

Q: What is the significance of AEC-Q200 qualification on the TDK substitutes?

A: AEC-Q200 is an automotive industry standard qualification for passive components. CLF7045T-221M-D and both LGJ7045TC variants carry this certification, indicating compliance with automotive reliability and testing requirements. This qualification provides additional assurance of component quality and performance consistency.

Q: Why is the saturation current (Isat) higher on substitute parts?

A: The main part CDRR75NP-221MC specifies Isat of 290 mA, while all TDK substitutes specify 620 mA. Higher saturation current indicates the inductor can handle greater current levels before magnetic saturation occurs. This represents an improvement in the substitute parts' performance margin.

Q: Can LGJ7045TC parts be used in new production designs?

A: LGJ7045TC-221M-D and LGJ7045TC-221M-H are classified as Obsolete. While existing inventory may be available, these parts are not recommended for new production designs due to discontinued manufacturer support and uncertain long-term availability. CLF7045T-221M-D (Active status) is the appropriate choice for new designs.
