CDPH64NP-100NC Equivalent & Substitute Parts

Part Overview

The CDPH64NP-100NC is a 10 µH shielded inductor manufactured by Sumida America Components Inc., rated for 1.32 A continuous current with a maximum DC resistance of 120mOhm. This surface mount component features a ferrite core and operates across the temperature range of -40°C to 100°C. The part is classified as obsolete, necessitating identification of equivalent substitute components that maintain functional compatibility while offering improved availability or enhanced performance characteristics within the same electrical and mechanical parameter space.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the CDPH64NP-100NC are qualified based on the following electrical and mechanical parameters:

Primary Matching Criteria:

• Inductance value: 10 µH (exact match required)
• Core material: Ferrite shielded construction
• Mounting type: Surface mount
• RoHS3 compliance and MSL Level 1 rating

Secondary Compatibility Parameters:

• Current rating: Minimum 1.32 A (equal or greater acceptable)
• DC resistance: Maximum 120mOhm (lower values acceptable for improved thermal performance)
• Operating temperature range: Minimum -40°C to 100°C coverage
• Package classification: Nonstandard surface mount form factor

Two substitute parts meet these criteria: the CDRH5D16NP-100MC (Sumida America Components Inc., active status) and the SRR7045-100M (Bourns Inc., active status). Both components maintain the 10 µH inductance specification, ferrite shielded construction, and surface mount configuration while offering enhanced current ratings and improved DC resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

CDRH5D16NP-100MC Selection Criteria:

The CDRH5D16NP-100MC is the primary substitute for direct replacement applications. Manufactured by the same supplier (Sumida America Components Inc.), this component maintains active product status and offers equivalent electrical performance. The inductance value, ferrite core construction, and shielding configuration are identical to the CDPH64NP-100NC. The current rating of 1.3 A is functionally equivalent to the 1.32 A specification of the main part. The DC resistance specification of 140 mOhm Max represents a marginal increase of 20 mOhm compared to the main part's 120 mOhm Max, which remains within acceptable tolerance for most circuit applications. The operating temperature range extends to 105°C, providing improved thermal margin. The CDRH5D16NP-100MC is available in Tape & Reel packaging with 4,300 pieces in stock inventory.

SRR7045-100M Selection Criteria:

The SRR7045-100M manufactured by Bourns Inc. serves as an alternative substitute offering enhanced performance characteristics. This component maintains the 10 µH inductance and ferrite shielded construction. The current rating of 2.7 A significantly exceeds the 1.32 A requirement, providing substantial design margin. The DC resistance of 42 mOhm Max is substantially lower than the main part's 120 mOhm specification, resulting in reduced power dissipation and improved thermal efficiency. The operating temperature range extends to 125°C. The SRR7045-100M features a drum core, wirewound construction type and is available in Cut Tape and Digi-Reel packaging with 7,692 pieces in stock inventory. Physical dimensions are larger (7.00mm x 7.00mm footprint) compared to the main part, requiring PCB layout verification.

Compliance and Certification:

Both substitute parts maintain ROHS3 compliance and MSL Level 1 rating, matching the environmental and regulatory requirements of the CDPH64NP-100NC. Both components are classified under ECCN EAR99 and HTSUS 8504.50.4000, consistent with the main part's export and tariff classification.

Frequently Asked Questions (FAQ)

Q: Can the CDRH5D16NP-100MC directly replace the CDPH64NP-100NC without circuit modification?

A: The CDRH5D16NP-100MC maintains electrical equivalence for the 10 µH inductance, current rating, and DC resistance specifications. The 20 mOhm increase in maximum DC resistance is within acceptable engineering tolerance for most applications. Physical dimensions differ (5.60mm x 5.60mm versus 6.60mm x 5.90mm), requiring PCB footprint verification. No circuit modification is required if PCB layout accommodates the smaller footprint.

Q: What are the advantages of selecting the SRR7045-100M over the CDRH5D16NP-100MC?

A: The SRR7045-100M offers superior performance characteristics: current rating of 2.7 A versus 1.3 A, providing 105% additional current capacity; DC resistance of 42 mOhm Max versus 140 mOhm Max, reducing power dissipation by 70%; operating temperature range to 125°C versus 105°C. These enhancements provide increased design margin and thermal efficiency. The trade-off is a larger physical footprint (7.00mm x 7.00mm) requiring PCB layout verification.

Q: Are there packaging considerations when substituting these parts?

A: The CDPH64NP-100NC original packaging specification is not provided. The CDRH5D16NP-100MC is supplied in Tape & Reel (TR) format, and the SRR7045-100M is supplied in Cut Tape (CT) and Digi-Reel format. Verify packaging compatibility with assembly equipment and procurement requirements.

Q: Do both substitute parts meet the same environmental and regulatory standards as the main part?

A: Both substitute parts are ROHS3 compliant with MSL Level 1 rating, matching the CDPH64NP-100NC specifications. Both are classified under ECCN EAR99 and HTSUS 8504.50.4000. The SRR7045-100M additionally carries REACH Unaffected status.

Q: What is the inductance tolerance specification for the substitute parts?

A: The CDRH5D16NP-100MC and SRR7045-100M both specify ±20% inductance tolerance, compared to the main part's -20%, +25% tolerance. The ±20% specification is more symmetrical and represents tighter tolerance control.

Q: Can the SRR7045-100M be used in applications requiring the exact current rating of 1.32 A?

A: The SRR7045-100M current rating of 2.7 A exceeds the 1.32 A requirement. This component is suitable for applications where the specified current rating is a minimum requirement. The higher current rating provides design margin and does not create incompatibility with circuits designed for 1.32 A operation.
