Parameter Comparison

Engineering Selection Recommendations

The CDEP85NP-100MC-125 is the qualified substitute for the obsolete CDEP106NP-100MC-88 based on the following engineering factors:

Electrical Compatibility: The substitute part maintains identical inductance (10 µH) and current rating (6.5 A) specifications. DC resistance of the CDEP85NP-100MC-125 (15.1 mOhm max) is lower than the original part (15.9 mOhm max), providing improved efficiency characteristics. Both components are tested at 100 kHz and feature ferrite shielded drum core construction.

Thermal Performance: The CDEP85NP-100MC-125 extends the operating temperature range to -40°C ~ 125°C, compared to the original -40°C ~ 105°C specification. This provides enhanced thermal margin for applications operating at elevated temperatures.

Compliance and Availability: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. The substitute part carries active product status with confirmed inventory availability (757 pcs), ensuring reliable supply chain support.

Physical Considerations: The CDEP85NP-100MC-125 features a smaller footprint (8.00mm x 8.00mm versus 10.00mm x 10.00mm) and reduced height (5.50mm versus 6.50mm). PCB layout verification is required to confirm dimensional compatibility with existing designs.

Saturation Current Difference: The substitute part exhibits lower saturation current (2.6 A versus 4.3 A). Applications requiring operation near saturation limits must evaluate this parameter against circuit design margins.

Frequently Asked Questions (FAQ)

Q: Can the CDEP85NP-100MC-125 directly replace the CDEP106NP-100MC-88 in existing designs?

A: Electrical substitution is valid based on matching inductance, current rating, and DC resistance specifications. Physical PCB layout verification is required due to reduced package dimensions (8mm x 8mm versus 10mm x 10mm) and height (5.50mm versus 6.50mm).

Q: What is the significance of the lower saturation current in the substitute part?

A: The CDEP85NP-100MC-125 has a saturation current of 2.6 A compared to 4.3 A in the original part. Applications operating with peak currents between 2.6 A and 4.3 A must evaluate whether this reduced saturation margin affects circuit performance and stability.

Q: Are both parts RoHS compliant?

A: Yes, both the CDEP106NP-100MC-88 and CDEP85NP-100MC-125 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.

Q: What is the packaging difference between these parts?

A: The CDEP106NP-100MC-88 packaging is listed as nonstandard. The CDEP85NP-100MC-125 is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes.

Q: Does the extended temperature range of the substitute part provide any advantage?

A: The CDEP85NP-100MC-125 operates to 125°C versus 105°C for the original part, providing 20°C additional thermal margin. This is beneficial for applications in high-temperature environments or with limited thermal management.

Q: How do the DC resistance values compare?

A: The substitute part (15.1 mOhm max) has lower DC resistance than the original (15.9 mOhm max), resulting in reduced power dissipation and improved efficiency in the same current-carrying application.
