Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDR95NP-220MC is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 22 µH (exact match required)
• Inductance tolerance: ±20% (exact match required)
• Shielding configuration: Unshielded (exact match required)
• Mounting type: Surface Mount (exact match required)

Secondary Compatibility Criteria:

• Current rating: Minimum 2.5 A (equal or greater acceptable)
• DC resistance: Maximum 68 mOhm (lower values acceptable; higher values require application verification)
• Operating temperature range: Minimum -40°C to 100°C coverage (extended ranges acceptable)
• RoHS3 compliance: Required for regulatory alignment
• MSL rating: 1 (Unlimited) for storage compatibility

All identified substitute parts meet the primary matching criteria. Secondary parameters vary within acceptable engineering tolerances for general-purpose inductor applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Highest Compatibility):

P0751.223NLT (Pulse Electronics) - Active status with extended operating temperature range to 130°C. Current rating of 2.6 A exceeds the original specification. DC resistance of 114 mOhm is higher than the original 68 mOhm; this increase may impact thermal performance in current-limited applications. Suitable for designs with thermal margin or lower sustained current operation.

SDR1005-220ML (Bourns Inc.) - Active status with established supply chain. Current rating of 2.0 A is below the original 2.5 A specification; this part is suitable only for applications operating at or below 2.0 A continuous current. DC resistance of 100 mOhm represents a moderate increase from the original specification.

74456122 (Würth Elektronik) - Active status with current rating of 2.6 A and DC resistance of 95 mOhm. Operating temperature range extends to 125°C. This part provides balanced performance between current capacity and resistance characteristics.

UP2B-220-R (Eaton - Electronics Division) - Active status with the lowest DC resistance at 61.7 mOhm, providing superior thermal efficiency. Current rating of 2.8 A exceeds original specification. Operating temperature range limited to 85°C maximum; this part is unsuitable for applications requiring operation above 85°C.

All substitute parts maintain RoHS3 compliance and MSL 1 rating, ensuring regulatory and storage compatibility with the original component.

Frequently Asked Questions (FAQ)

Q: Can SDR1005-220ML replace CDR95NP-220MC in all applications?

A: No. SDR1005-220ML has a current rating of 2.0 A, which is below the original 2.5 A specification. This part is suitable only for applications where sustained current does not exceed 2.0 A. Applications requiring the full 2.5 A rating must use alternative substitutes.

Q: What is the impact of higher DC resistance in substitute parts?

A: DC resistance directly affects power dissipation and thermal performance. P0751.223NLT (114 mOhm) and SDR1005-220ML (100 mOhm) exhibit higher resistance than the original 68 mOhm specification. In applications with sustained high current, this increased resistance generates additional heat. UP2B-220-R (61.7 mOhm) provides lower resistance and improved thermal efficiency.

Q: Are all substitute parts available in the same package?

A: All substitute parts are surface mount inductors with nonstandard packages. Physical dimensions vary slightly between manufacturers. Verify PCB footprint compatibility before design implementation. Specific dimensions are provided in the parameter comparison table.

Q: Which substitute part has the best long-term availability?

A: All identified substitutes maintain active product status. UP2B-220-R shows the highest inventory level (16,263 pcs), followed by SDR1005-220ML (4,200 pcs). Active status indicates ongoing manufacturer support and procurement availability.

Q: Can UP2B-220-R be used in applications operating above 85°C?

A: No. UP2B-220-R has a maximum operating temperature of 85°C. Applications requiring operation at the original specification range of -40°C to 100°C must use P0751.223NLT, SDR1005-220ML, or 74456122, all of which support operation to at least 125°C.

Q: What is the significance of the ±20% inductance tolerance?

A: All parts, including the original and substitutes, share ±20% inductance tolerance. This tolerance is acceptable for general-purpose filtering and energy storage applications. Applications requiring tighter inductance tolerance must be evaluated separately.
