CDRR75NP-220MC Equivalent & Substitute Parts

Part Overview

The CDRR75NP-220MC is a 22 µH shielded inductor manufactured by Sumida America Components Inc., designed for surface mount applications requiring fixed inductance with moderate current handling. This component features a ferrite core with 85mOhm maximum DC resistance and operates across the -40°C to 125°C temperature range. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative electrical or mechanical characteristics within acceptable tolerance bands. The substitute inductors listed maintain the core 22 µH inductance specification while offering variations in current rating, DC resistance, temperature range, and physical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDRR75NP-220MC is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 22 µH (fixed requirement)
• Inductance tolerance: ±20% (fixed requirement)
• Core material: Ferrite (fixed requirement)
• Shielding: Shielded (fixed requirement)
• Mounting type: Surface Mount (fixed requirement)
• Test frequency: 100 kHz (fixed requirement)

Allowable Variation Parameters:

• Current rating: Substitute must equal or exceed 1.7 A
• DC resistance: Substitute must not exceed 85 mOhm maximum
• Saturation current: Substitute must equal or exceed 960 mA
• Operating temperature range: Substitute must support minimum -40°C to 125°C
• Physical dimensions: Substitute package must fit within or match the 6.90mm x 6.90mm x 4.80mm envelope
• RoHS compliance: ROHS3 compliance required
• Moisture sensitivity: MSL 1 (Unlimited) required

The three substitute parts listed (CLF7045T-220M-D, LGJ7045TC-220M-D, and LGJ7045TC-220M-H) meet all primary criteria and fall within allowable variation parameters for their respective electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

CLF7045T-220M-D (TDK Corporation): This substitute offers the most direct electrical compatibility with the CDRR75NP-220MC. The CLF7045T-220M-D maintains active product status, carries AEC-Q200 automotive qualification, and provides superior DC resistance performance at 82.8 mOhm maximum. The extended operating temperature range to 150°C provides additional thermal margin. Physical dimensions increase marginally in length (7.20mm vs 6.90mm) while maintaining identical width and height. This part is suitable for applications where the slightly larger footprint can be accommodated and where automotive-grade reliability is beneficial.

LGJ7045TC-220M-D (TDK Corporation): This substitute provides the lowest DC resistance at 69 mOhm, resulting in reduced power dissipation compared to the main part. The LGJ7045TC-220M-D carries AEC-Q200 qualification and supports the extended -40°C to 150°C temperature range. However, this part carries obsolete product status, indicating discontinued production. The reduced height (4.50mm vs 4.80mm) may provide board layout advantages. Selection of this part should account for long-term supply availability constraints.

LGJ7045TC-220M-H (TDK Corporation): This substitute matches the CDRR75NP-220MC operating temperature range (-40°C to 125°C) while providing superior DC resistance at 69 mOhm. The LGJ7045TC-220M-H carries AEC-Q200 qualification and reduced height (4.50mm). Like the LGJ7045TC-220M-D variant, this part carries obsolete product status. The -H suffix indicates a specific packaging or handling variant. Selection requires confirmation of long-term supply viability.

Primary Recommendation: For new designs or applications requiring sustained component availability, CLF7045T-220M-D is the preferred substitute, offering active production status combined with superior electrical performance and automotive-grade certification.

Frequently Asked Questions (FAQ)

Q: Can the LGJ7045TC-220M-D or LGJ7045TC-220M-H be used as direct replacements despite obsolete status?

A: These parts meet all electrical and mechanical substitution criteria and remain functionally compatible with the CDRR75NP-220MC. However, obsolete status indicates discontinued production. Substitution is technically valid but requires verification of available inventory and acceptable lead times for your application timeline.

Q: What is the significance of the 0.30mm length difference between the main part and TDK substitutes?

A: The CDRR75NP-220MC measures 6.90mm in length while CLF7045T-220M-D, LGJ7045TC-220M-D, and LGJ7045TC-220M-H measure 7.20mm. This 0.30mm increase requires verification against PCB layout constraints and component placement clearances. Most modern PCB designs accommodate this variation without modification.

Q: Why do the TDK substitutes have lower DC resistance values?

A: The CLF7045T-220M-D specifies 82.8 mOhm maximum, while the LGJ variants specify 69 mOhm. Lower DC resistance reduces resistive losses and heat generation during operation. This represents improved performance relative to the 85 mOhm maximum of the CDRR75NP-220MC. Applications sensitive to power dissipation benefit from this characteristic.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The CDRR75NP-220MC and all three substitute parts (CLF7045T-220M-D, LGJ7045TC-220M-D, LGJ7045TC-220M-H) carry ROHS3 compliance certification. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What does AEC-Q200 certification indicate?

A: AEC-Q200 is an automotive electronics qualification standard. The three TDK substitute parts carry this certification, indicating qualification for automotive applications. The main CDRR75NP-220MC does not specify this rating. If automotive qualification is required, TDK substitutes provide this assurance.

Q: Can height differences affect circuit performance?

A: The height variation between the main part (4.80mm maximum) and LGJ variants (4.50mm maximum) does not affect electrical performance. The 0.30mm reduction may provide minor PCB clearance advantages in space-constrained designs. The CLF7045T-220M-D maintains identical 4.80mm height to the main part.

Q: What packaging formats are available for these parts?

A: The CDRR75NP-220MC is supplied in Tape & Reel (TR) format. The CLF7045T-220M-D is supplied in Tape & Reel (TR) format. The LGJ7045TC-220M-D and LGJ7045TC-220M-H are supplied in Cut Tape (CT) & Digi-Reel® format. Packaging format selection depends on assembly process requirements and order quantities.
