Substitute Part Grouping Explanation

Substitution of the CDEP105-2R5MC-32 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Inductance value: 2.5 µH at ±20% tolerance
• Current rating: 6.2 A minimum
• Saturation current: 14 A minimum
• DC resistance: 18 mOhm maximum
• Core type: Ferrite drum core, shielded configuration
• Mounting: Surface mount, nonstandard package
• Physical footprint: 10.00 mm x 10.00 mm x 5.60 mm maximum height
• Operating temperature: -40°C to 125°C

The CDEP105NP-2R5MC-32 meets all electrical and mechanical specifications required for direct substitution. The primary distinction is product status and packaging format, not functional performance.

Parameter Comparison

Engineering Selection Recommendations

The CDEP105NP-2R5MC-32 is the direct functional equivalent of the obsolete CDEP105-2R5MC-32. Selection of the substitute part is based on the following engineering factors:

Product Status: The CDEP105-2R5MC-32 is classified as obsolete. The CDEP105NP-2R5MC-32 maintains active product status with Sumida America Components Inc., ensuring continued availability and manufacturing support.

Regulatory Compliance: The substitute part CDEP105NP-2R5MC-32 is ROHS3 compliant, whereas the main part is RoHS non-compliant. For applications subject to RoHS directives or customer compliance requirements, the substitute part satisfies regulatory obligations.

Packaging Format: The main part is supplied in bulk packaging. The substitute part is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes and high-volume production environments.

Electrical and Mechanical Equivalence: All critical parameters—inductance, current rating, saturation current, DC resistance, core material, shielding, mounting type, physical dimensions, and operating temperature range—are identical between the two parts. Direct substitution in existing designs requires no circuit modifications or thermal management adjustments.

Frequently Asked Questions (FAQ)

Q: Can the CDEP105NP-2R5MC-32 be used as a direct replacement for the CDEP105-2R5MC-32 in existing designs?

A: Yes. The CDEP105NP-2R5MC-32 is electrically and mechanically equivalent to the CDEP105-2R5MC-32. All functional parameters, including inductance, current rating, DC resistance, and physical dimensions, are identical. No circuit redesign is required.

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

A: The primary differences are product status and packaging format. The CDEP105-2R5MC-32 is obsolete and supplied in bulk. The CDEP105NP-2R5MC-32 is active and supplied in Tape & Reel format. Additionally, the substitute part is ROHS3 compliant while the main part is not.

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

A: No. Both parts operate across the same temperature range (-40°C to 125°C), have identical current ratings (6.2 A), saturation current (14 A), and DC resistance (18 mOhm maximum). Thermal and electrical performance are equivalent.

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

A: No. Tape & Reel packaging is a delivery and handling format used for automated assembly. It does not affect the electrical or mechanical properties of the inductor itself. The component specifications remain unchanged.

Q: Is the CDEP105NP-2R5MC-32 suitable for applications requiring RoHS compliance?

A: Yes. The CDEP105NP-2R5MC-32 is ROHS3 compliant. If your application or customer requirements mandate RoHS compliance, this substitute part satisfies those requirements. The original CDEP105-2R5MC-32 is RoHS non-compliant.

Q: What is the moisture sensitivity level for the substitute part?

A: The CDEP105NP-2R5MC-32 has a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without special moisture control measures. Standard storage conditions are acceptable.

Q: Can I mix the CDEP105-2R5MC-32 and CDEP105NP-2R5MC-32 in the same production batch?

A: Yes. Both parts are electrically and mechanically identical. They can be used interchangeably in the same circuit design and production environment. However, the Tape & Reel format of the substitute part is optimized for automated assembly, while bulk packaging may require manual handling.
