Engineering Selection Recommendations

The CDEP105NP-3R2MC-50 is the direct equivalent substitute for the obsolete CDEP105-3R2MC-50. Selection of the substitute part is based on the following engineering factors:

Product Status: The main part CDEP105-3R2MC-50 is classified as obsolete. The substitute CDEP105NP-3R2MC-50 maintains active product status, ensuring long-term availability and manufacturing support.

Electrical and Mechanical Equivalence: All critical electrical parameters (inductance, current rating, saturation current, DC resistance) and mechanical parameters (dimensions, mounting type, core material, shielding) are identical between the main part and substitute.

Compliance Enhancement: The substitute part achieves ROHS3 compliance, whereas the main part is RoHS non-compliant. This represents an improvement in regulatory compliance for new designs and procurement.

Packaging: The substitute is supplied in standard Tape & Reel (TR) packaging, which facilitates automated assembly processes and improves supply chain efficiency compared to the unspecified packaging of the main part.

Series Continuity: Both parts belong to the CDEP105 series, confirming design continuity and interchangeability within the product line.

Frequently Asked Questions (FAQ)

Q: Can CDEP105NP-3R2MC-50 be used as a direct replacement for CDEP105-3R2MC-50?

A: Yes. The CDEP105NP-3R2MC-50 is a direct equivalent substitute. All electrical parameters (3.2 µH inductance, 7.4 A current rating, 12.4 mOhm DCR, 10.5 A saturation current) and mechanical parameters (dimensions, mounting type, core material, shielding) are identical. The substitute is the recommended choice for new procurement due to its active product status and improved RoHS compliance.

Q: What is the difference between CDEP105-3R2MC-50 and CDEP105NP-3R2MC-50?

A: The primary differences are product status and compliance. CDEP105-3R2MC-50 is obsolete with RoHS non-compliant status, while CDEP105NP-3R2MC-50 is active with ROHS3 compliance. The "NP" designation in the substitute part number indicates the updated product variant. All functional electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these parts?

A: Yes. CDEP105-3R2MC-50 has unspecified packaging, while CDEP105NP-3R2MC-50 is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for surface mount components and is compatible with automated pick-and-place assembly equipment.

Q: Will the substitute part work in existing PCB designs?

A: Yes. The CDEP105NP-3R2MC-50 has identical physical dimensions (10.00 mm L x 10.00 mm W x 5.60 mm H), mounting type (surface mount), and electrical specifications. No PCB layout modifications are required.

Q: What is the inductance tolerance for these parts?

A: Both parts have an inductance tolerance of ±20% at the 100 kHz test frequency. This tolerance applies to the 3.2 µH nominal inductance value.

Q: Are these parts suitable for high-temperature applications?

A: Yes. Both parts operate across the temperature range of -40°C to 125°C, which covers standard industrial and automotive temperature requirements.

Q: What is the current handling capability?

A: Both parts are rated for 7.4 A continuous current with a saturation current (Isat) of 10.5 A. The DC resistance is 12.4 mOhm maximum, which determines the resistive losses at rated current.
