Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDEP105-1R5MC-32 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 1.5 µH
• Inductance tolerance: ±20%
• Current rating: 7.8 A minimum
• Saturation current: 18 A minimum
• DC resistance: 10.5 mOhm maximum

Physical & Mechanical Parameters:

• Core type: Ferrite drum core, wirewound
• Shielding: Shielded construction
• Mounting: Surface mount
• Package dimensions: 10.00 mm x 10.00 mm x 5.60 mm maximum height
• Temperature range: -40°C to 125°C minimum

Environmental & Compliance Parameters:

• Moisture sensitivity: MSL 1 or better
• Operating frequency: 100 kHz test point

Only components matching all these parameters across electrical, mechanical, and environmental specifications are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The CDEP105NP-1R5MC-32 is the direct substitute for the obsolete CDEP105-1R5MC-32. Both components are manufactured by Sumida America Components Inc. within the CDEP105 series and share identical electrical and mechanical specifications across all critical parameters.

Key Differentiation Factors:

Product Status: The CDEP105NP-1R5MC-32 maintains active product status, ensuring continued availability and manufacturer support. The original CDEP105-1R5MC-32 is classified as obsolete and subject to discontinuation.

Compliance Status: The substitute part (CDEP105NP-1R5MC-32) is ROHS3 compliant, whereas the main part is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations in the European Union and equivalent jurisdictions.

Packaging Configuration: The main part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel (TR) format. This difference affects procurement workflows and automated assembly processes but does not alter component functionality or electrical performance.

Electrical & Mechanical Equivalence: All electrical parameters (inductance, current rating, saturation current, DC resistance) and mechanical parameters (dimensions, core material, shielding, mounting type) are identical between the two parts. Direct substitution is supported without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can CDEP105NP-1R5MC-32 be used as a direct replacement for CDEP105-1R5MC-32 in existing designs?

A: Yes. The CDEP105NP-1R5MC-32 is electrically and mechanically equivalent to the CDEP105-1R5MC-32. All critical parameters including inductance (1.5 µH), current rating (7.8 A), DC resistance (10.5 mOhm max), and physical dimensions (10.00 mm x 10.00 mm x 5.60 mm) are identical. Direct substitution is supported without circuit modification.

Q: What is the difference between the packaging formats?

A: The CDEP105-1R5MC-32 is supplied in bulk packaging, while the CDEP105NP-1R5MC-32 is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly processes. Both formats contain the same component with identical electrical and mechanical specifications.

Q: Why is RoHS compliance status different between the two parts?

A: The CDEP105-1R5MC-32 is RoHS non-compliant, while the CDEP105NP-1R5MC-32 is ROHS3 compliant. This reflects manufacturing process updates and material composition changes implemented by Sumida America Components Inc. For applications subject to RoHS regulations, the CDEP105NP-1R5MC-32 is the required selection.

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

A: No. Both parts are rated for 1.5 µH inductance at ±20% tolerance, 7.8 A continuous current, 18 A saturation current, and 10.5 mOhm maximum DC resistance. Electrical performance is identical across all specified parameters.

Q: What is the current availability status of each part?

A: The CDEP105-1R5MC-32 (obsolete) has 742 pieces in stock. The CDEP105NP-1R5MC-32 (active) has 1082 pieces in stock. For new designs and long-term procurement, the active part (CDEP105NP-1R5MC-32) is recommended.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the CDEP105-1R5MC-32 and CDEP105NP-1R5MC-32 operate across the identical temperature range of -40°C to 125°C with no performance degradation within this specification.

Q: Can these parts be used interchangeably in automated assembly?

A: The CDEP105NP-1R5MC-32 in Tape & Reel format is optimized for automated assembly. The CDEP105-1R5MC-32 in bulk packaging requires manual handling or custom feeder configuration. From a component functionality perspective, they are interchangeable; assembly process compatibility depends on equipment configuration.
