Substitute Part Grouping Explanation

Substitution of the CDEP105-3R0MC-32 is based on strict equivalence of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 3 µH
• Inductance tolerance: ±20%
• Current rating: 4.9 A
• Saturation current: 12.6 A
• DC resistance: 23.8 mOhm maximum
• Core type: Ferrite drum core, shielded
• Operating temperature range: -40°C to 125°C
• Package dimensions: 10.00 mm × 10.00 mm × 5.60 mm maximum height
• Mounting type: Surface mount

The CDEP105NP-3R0MC-32 qualifies as a direct substitute because it maintains all electrical specifications and mechanical dimensions while differing only in packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The CDEP105NP-3R0MC-32 is the direct equivalent substitute for the obsolete CDEP105-3R0MC-32. Selection of the substitute part is justified on the following basis:

Product Status: The CDEP105-3R0MC-32 is classified as obsolete, whereas the CDEP105NP-3R0MC-32 maintains active product status with current manufacturing availability.

Compliance Certifications: The substitute part achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification and EAR99 export control designation.

Electrical and Mechanical Equivalence: All critical parameters—inductance, current rating, saturation current, DC resistance, core material, shielding, operating temperature range, and package dimensions—are identical between the two parts.

Packaging Consideration: The primary difference is packaging format. The CDEP105NP-3R0MC-32 is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations. The original part uses a nonstandard packaging format.

For new designs and production continuity, the CDEP105NP-3R0MC-32 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the CDEP105NP-3R0MC-32 be used as a direct replacement for the CDEP105-3R0MC-32 in existing designs?

A: Yes. The CDEP105NP-3R0MC-32 is electrically and mechanically equivalent. All inductance, current, resistance, temperature, and dimensional specifications are identical. The parts are interchangeable at the circuit level.

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

A: The primary differences are product status and packaging format. The CDEP105-3R0MC-32 is obsolete and uses nonstandard packaging. The CDEP105NP-3R0MC-32 is active production and supplied in standard Tape & Reel format. The CDEP105NP-3R0MC-32 also achieves ROHS3 compliance.

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

A: No. Both parts have identical inductance (3 µH), current rating (4.9 A), saturation current (12.6 A), DC resistance (23.8 mOhm maximum), and operating temperature range (-40°C to 125°C).

Q: Does the Tape & Reel packaging affect component performance?

A: No. Tape & Reel is a standard packaging and handling format for surface mount components. It does not affect electrical or mechanical performance. The component itself is identical.

Q: Is the CDEP105NP-3R0MC-32 suitable for high-volume production?

A: Yes. The active product status and Tape & Reel packaging format make the CDEP105NP-3R0MC-32 suitable for automated surface mount assembly in production environments.

Q: What is the significance of ROHS3 compliance on the substitute part?

A: ROHS3 compliance indicates the part meets current environmental and material restriction standards. This is relevant for applications subject to regulatory requirements or customer specifications mandating RoHS compliance.
