Engineering Selection Recommendations

The CDEP147NP-2R4MC-95 is a direct functional substitute for the obsolete CDEP106NP-2R4MC-50 based on the following engineering criteria:

Electrical Compatibility: Both inductors provide identical 2.4 µH inductance at ±20% tolerance with ferrite shielded drum core construction. The CDEP147NP-2R4MC-95 maintains full electrical equivalence while providing superior performance margins: 75% higher continuous current rating (17.5 A vs. 10 A), 65% higher saturation current (22.4 A vs. 13.6 A), and 50% lower DC resistance (3.23 mOhm vs. 6.4 mOhm maximum).

Thermal Performance: The substitute part extends the operating temperature range to -40°C to 125°C, providing an additional 20°C upper temperature margin compared to the original specification.

Compliance & Availability: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. The CDEP147NP-2R4MC-95 is classified as active product status with current manufacturing availability, eliminating supply chain risk associated with the obsolete CDEP106NP-2R4MC-50.

Physical Considerations: The substitute part requires a larger PCB footprint (14.50mm x 14.50mm vs. 10.00mm x 10.00mm) and greater height clearance (8.00mm vs. 6.50mm maximum). Design layout verification is necessary to confirm accommodation of these dimensional differences.

Packaging: The CDEP147NP-2R4MC-95 is supplied in standard Tape & Reel (TR) packaging, improving handling efficiency and supply chain standardization compared to the nonstandard packaging of the original part.

Frequently Asked Questions (FAQ)

Q: Can the CDEP147NP-2R4MC-95 be used as a direct replacement for the CDEP106NP-2R4MC-50 in existing designs?

A: Electrical substitution is valid. The CDEP147NP-2R4MC-95 provides identical inductance and tolerance with superior current handling and lower DC resistance. However, physical layout verification is required due to increased footprint (14.50mm x 14.50mm vs. 10.00mm x 10.00mm) and height (8.00mm vs. 6.50mm maximum).

Q: What are the key electrical differences between these two inductors?

A: Both parts deliver 2.4 µH inductance at ±20% tolerance. The CDEP147NP-2R4MC-95 exceeds the original specification in continuous current rating (17.5 A vs. 10 A), saturation current (22.4 A vs. 13.6 A), and provides superior DC resistance performance (3.23 mOhm vs. 6.4 mOhm maximum). Operating temperature range extends from 105°C to 125°C maximum.

Q: Are there any compliance or certification concerns with substitution?

A: Both inductors maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. No compliance barriers exist for substitution.

Q: Why is the CDEP106NP-2R4MC-50 classified as obsolete?

A: The CDEP106NP-2R4MC-50 is no longer in active production. The CDEP147NP-2R4MC-95 represents the current active equivalent from Sumida America Components Inc., offering improved electrical performance and standard packaging.

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

A: The CDEP147NP-2R4MC-95 is supplied in Tape & Reel (TR) standard packaging, providing improved handling and supply chain efficiency compared to the nonstandard packaging of the original part.

Q: Will the larger physical dimensions of the CDEP147NP-2R4MC-95 affect circuit performance?

A: Physical dimensions do not affect electrical performance. The larger footprint and height are consequences of the enhanced current rating and lower DC resistance design. PCB layout must accommodate the increased space requirements.
