CDPH64NP-680NC Equivalent & Substitute Parts

Part Overview

The CDPH64NP-680NC is a 68 µH shielded inductor manufactured by Sumida America Components Inc., rated for 500 mA continuous current with a maximum DC resistance of 490 mOhm. 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 alternatives for ongoing design requirements and procurement continuity. Substitute parts must maintain the core electrical specifications: 68 µH inductance, 500 mA minimum current rating, shielded ferrite construction, and surface mount packaging.

Engineering Selection Recommendations

CDRH5D16NP-680MC (Sumida America Components Inc.)

This part is the primary substitute for the obsolete CDPH64NP-680NC. Both components are manufactured by Sumida and share identical inductance (68 µH) and current rating (500 mA) specifications. The CDRH5D16NP-680MC is in active production status, ensuring long-term availability and supply chain continuity. The part maintains ROHS3 compliance and MSL 1 rating. The DC resistance is higher at 860 mOhm compared to 490 mOhm, which must be evaluated against circuit performance requirements. The physical footprint is smaller (5.60mm x 5.60mm vs. 6.60mm x 5.90mm) with significantly reduced height (1.80mm vs. 5.00mm), offering potential PCB layout advantages. The operating temperature range extends to 105°C, providing improved thermal margin.

SRR7045-680M (Bourns Inc.)

This part serves as an alternative substitute with enhanced electrical performance characteristics. The SRR7045-680M maintains the 68 µH inductance and exceeds the 500 mA current requirement with a 1.2 A rating and 750 mA saturation current. The DC resistance is significantly lower at 210 mOhm, reducing power dissipation in current-carrying applications. The part features drum core, wirewound construction with documented Q factor (22 @ 2.52MHz) and self-resonant frequency (10MHz). ROHS3 compliance and MSL 1 rating are maintained. The operating temperature range extends to 125°C. The physical footprint is larger (7.00mm x 7.00mm) and requires PCB layout verification for compatibility. Active production status ensures availability.

Selection Criteria:

• For direct form-fit-function replacement with minimal PCB redesign: CDRH5D16NP-680MC
• For applications requiring lower DC resistance and higher current margin: SRR7045-680M
• Both parts satisfy RoHS3 compliance and moisture sensitivity requirements
• PCB layout constraints determine final selection based on available space

Frequently Asked Questions (FAQ)

Q: Can the CDRH5D16NP-680MC directly replace the CDPH64NP-680NC without circuit modification?

A: The CDRH5D16NP-680MC matches the inductance value (68 µH) and current rating (500 mA) of the obsolete part. However, the DC resistance differs (860 mOhm vs. 490 mOhm). Circuit performance must be evaluated to determine if the increased resistance is acceptable. The smaller physical footprint (5.60mm x 5.60mm vs. 6.60mm x 5.90mm) and reduced height (1.80mm vs. 5.00mm) require PCB layout verification.

Q: What is the primary difference between CDRH5D16NP-680MC and SRR7045-680M?

A: Both parts maintain 68 µH inductance and exceed the 500 mA minimum current requirement. The SRR7045-680M offers lower DC resistance (210 mOhm vs. 860 mOhm), higher current rating (1.2 A vs. 500 mA), and documented frequency characteristics (Q factor and self-resonant frequency). The SRR7045-680M has a larger footprint (7.00mm x 7.00mm) compared to CDRH5D16NP-680MC (5.60mm x 5.60mm).

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both CDRH5D16NP-680MC and SRR7045-680M are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), matching the compliance profile of the original CDPH64NP-680NC.

Q: What packaging formats are available for the substitute parts?

A: Both CDRH5D16NP-680MC and SRR7045-680M are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: How do the operating temperature ranges compare?

A: The original CDPH64NP-680NC operates from -40°C to 100°C. The CDRH5D16NP-680MC extends to 105°C, and the SRR7045-680M extends to 125°C, providing additional thermal margin in both substitute options.

Q: Which substitute part has the lowest DC resistance?

A: The SRR7045-680M has the lowest DC resistance at 210 mOhm maximum, compared to 490 mOhm (original) and 860 mOhm (CDRH5D16NP-680MC). Lower DC resistance reduces power dissipation and heat generation in the inductor.

Q: Are there inventory considerations for these substitute parts?

A: The CDRH5D16NP-680MC has 764 pieces in stock, and the SRR7045-680M has 17,189 pieces in stock, both available as new original components. The original CDPH64NP-680NC has 639 pieces remaining in inventory but is classified as obsolete.
