Substitute Part Grouping Explanation

Substitution of the CDEP105-0R8MC-32 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Inductance value: 800 nH
• Inductance tolerance: ±20%
• Current rating: 11.2 A minimum
• Saturation current: 25.2 A minimum
• DC resistance: 5.3 mOhm maximum
• Core material: Ferrite
• Shielding: Shielded construction

Mechanical Parameters (Must Match):

• Mounting type: Surface Mount
• Physical dimensions: 10.00 mm x 10.00 mm x 5.60 mm (Max height)
• Package classification: Nonstandard

Environmental Parameters (Must Match):

• Operating temperature range: -40°C to 125°C minimum
• Inductance test frequency: 100 kHz

The CDEP105NP-0R8MC-32 meets all electrical, mechanical, and environmental specifications required for direct substitution. The primary distinction between the main part and its substitute is product status and packaging configuration, not functional performance.

Engineering Selection Recommendations

The CDEP105NP-0R8MC-32 is the direct functional equivalent of the CDEP105-0R8MC-32 and is suitable for substitution in all applications where the original part was specified. Selection of the substitute part is justified on the following grounds:

Product Status: The CDEP105-0R8MC-32 is classified as obsolete. The CDEP105NP-0R8MC-32 maintains active product status with Sumida America Components Inc., ensuring continued availability and supply chain reliability.

Electrical Equivalence: All critical electrical parameters are identical, including inductance value, current ratings, saturation characteristics, and DC resistance specifications. The parts are functionally interchangeable at the circuit level.

Compliance Status: The CDEP105NP-0R8MC-32 is ROHS3 compliant, whereas the original part is non-compliant. For applications subject to RoHS regulations or customer requirements, the substitute part satisfies compliance mandates.

Mechanical Compatibility: Physical dimensions and mounting characteristics are identical, permitting direct PCB layout compatibility without redesign.

Packaging Consideration: The substitute part is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly operations. The original part was supplied in bulk packaging. This difference does not affect electrical or mechanical performance but may require adjustment to procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CDEP105NP-0R8MC-32 be used as a direct replacement for CDEP105-0R8MC-32 in existing designs?

A: Yes. The CDEP105NP-0R8MC-32 is electrically and mechanically equivalent to the CDEP105-0R8MC-32. All critical parameters including inductance, current rating, DC resistance, core material, shielding, dimensions, and operating temperature range are identical. Direct substitution is permissible without circuit redesign or PCB layout modification.

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

A: The primary differences are product status and packaging format. The CDEP105-0R8MC-32 is obsolete and supplied in bulk packaging. The CDEP105NP-0R8MC-32 is an active product supplied in Tape & Reel (TR) packaging and includes ROHS3 compliance certification. The "NP" designation in the part number indicates the newer packaging variant.

Q: Are there any electrical performance differences between the two parts?

A: No. Both parts are manufactured to identical electrical specifications. Inductance value, tolerance, current rating, saturation current, DC resistance, core material, and shielding characteristics are equivalent. Performance in circuit applications will be identical.

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

A: No. Packaging format does not affect electrical or mechanical performance. Tape & Reel packaging is a supply and assembly format consideration only. The component itself functions identically regardless of packaging method.

Q: Is the CDEP105NP-0R8MC-32 suitable for applications requiring RoHS compliance?

A: Yes. The CDEP105NP-0R8MC-32 is ROHS3 compliant. If your application or customer requirements mandate RoHS compliance, this substitute part satisfies those requirements, whereas the original CDEP105-0R8MC-32 does not.

Q: Can I mix inventory of both parts in production?

A: Yes, provided your assembly process can accommodate both bulk and Tape & Reel packaging formats. Electrically and mechanically, the parts are fully interchangeable. Inventory management and assembly line configuration are the only operational considerations.

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

A: The CDEP105-0R8MC-32 has 626 pieces in stock but is classified as obsolete with no ongoing production. The CDEP105NP-0R8MC-32 is an active product with 1067 pieces in stock and ongoing manufacturing support from Sumida America Components Inc.
