• Current rating: 17.7 A minimum
• Saturation current: 26.4 A minimum
• DC resistance: 2.4 mOhm maximum
• Core material: Ferrite
• Shielding: Shielded construction

Mechanical Parameters (Must Match):

• Mounting type: Surface Mount
• Package dimensions: 10.00 mm L x 10.00 mm W x 5.60 mm H maximum
• Core type: Drum core, wirewound

Environmental Parameters (Must Match):

• Operating temperature range: -40°C to 125°C minimum
• Moisture sensitivity level: 1 (Unlimited)

The CDEP105NP-0R4MC-50 meets all substitution criteria as a direct equivalent with identical electrical and mechanical specifications. The primary distinction is product status and packaging format.

Engineering Selection Recommendations

The CDEP105NP-0R4MC-50 is the direct functional equivalent of the obsolete CDEP105-0R4MC-50. Selection of the substitute part is based on the following engineering factors:

Product Status: The CDEP105-0R4MC-50 is classified as obsolete, making the active CDEP105NP-0R4MC-50 the appropriate choice for new designs and ongoing production requirements.

Electrical Equivalence: Both parts deliver identical electrical performance across all specified parameters, including inductance, current rating, saturation characteristics, and DC resistance. No circuit redesign or performance adjustment is required.

Mechanical Compatibility: Identical footprint and height specifications ensure direct board-level substitution without layout modifications.

Regulatory Compliance: The CDEP105NP-0R4MC-50 achieves ROHS3 compliance, whereas the main part is non-compliant. For applications subject to RoHS requirements, the substitute part satisfies regulatory obligations.

Packaging Consideration: The substitute part is supplied in Tape & Reel format, which is standard for automated assembly processes. The main part bulk packaging is no longer actively produced.

Frequently Asked Questions (FAQ)

Q: Can the CDEP105NP-0R4MC-50 be used as a direct replacement for the CDEP105-0R4MC-50 in existing designs?

A: Yes. The CDEP105NP-0R4MC-50 is electrically and mechanically identical to the CDEP105-0R4MC-50. All electrical parameters, physical dimensions, and operating characteristics are equivalent. Direct substitution requires no circuit modifications or performance validation.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging format. The CDEP105-0R4MC-50 is obsolete and supplied in bulk packaging. The CDEP105NP-0R4MC-50 is active production and supplied in Tape & Reel format. The CDEP105NP-0R4MC-50 also achieves ROHS3 compliance, whereas the main part does not.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts are specified with identical inductance (450 nH), current rating (17.7 A), saturation current (26.4 A), and DC resistance (2.4 mOhm maximum). Electrical performance is equivalent across all operating conditions within the specified temperature range.

Q: Does the Tape & Reel packaging of the substitute part affect compatibility?

A: No. Tape & Reel packaging is a supply format only and does not affect component electrical or mechanical characteristics. The physical component itself is identical. Tape & Reel format is standard for automated assembly processes and is compatible with standard pick-and-place equipment.

Q: Is RoHS compliance a functional requirement for this substitution?

A: RoHS compliance is a regulatory and supply chain consideration, not a functional electrical requirement. The CDEP105NP-0R4MC-50 achieves ROHS3 compliance, making it suitable for applications subject to RoHS directives. The original part is non-compliant. Selection should be based on applicable regulatory requirements for your application.

Q: Can I use the CDEP105-0R4MC-50 if I have existing inventory?

A: Yes, if the part meets your application requirements and regulatory obligations. However, for new production orders and long-term supply continuity, the CDEP105NP-0R4MC-50 is recommended as the active equivalent.
