Substitute Part Grouping Explanation

Substitution of the CDEP105-3R2MC-88 is determined by strict equivalence across the following critical parameters:

Inductance Value: 3.2 µH at 100 kHz test frequency with ±20% tolerance Current Rating: 9 A continuous current capability Saturation Current: 7.8 A minimum threshold DC Resistance: 7.5 mOhm maximum Core Construction: Ferrite material with shielding Mounting Configuration: Surface mount, nonstandard package footprint Physical Envelope: 10.00 mm × 10.00 mm × 5.60 mm maximum height Temperature Performance: -40°C to 125°C operating range

The CDEP105NP-3R2MC-88 qualifies as a direct substitute because it maintains identical electrical specifications and physical dimensions while differing only in packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The CDEP105NP-3R2MC-88 is the direct substitute for the obsolete CDEP105-3R2MC-88. Both parts are manufactured by Sumida America Components Inc. and share identical electrical and mechanical specifications across all critical parameters including inductance, current rating, DC resistance, core material, shielding, and physical dimensions.

Product Status Consideration: The main part CDEP105-3R2MC-88 is classified as obsolete, while the substitute CDEP105NP-3R2MC-88 maintains active product status with current manufacturing availability. This transition ensures continued supply chain access for new production and replacement applications.

Compliance Differentiation: The substitute part CDEP105NP-3R2MC-88 is ROHS3 compliant, whereas the main part is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations and environmental compliance requirements in the European Union and equivalent jurisdictions.

Packaging Format: The primary difference between the two parts is packaging. The main part is supplied in bulk format, while the substitute is supplied in Tape & Reel (TR) format, which is standard for automated assembly operations and provides improved handling and traceability.

Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification and identical ECCN and HTSUS codes, confirming regulatory equivalence for export and import purposes.

Frequently Asked Questions (FAQ)

Q: Can CDEP105NP-3R2MC-88 be used as a direct replacement for CDEP105-3R2MC-88 in existing designs?

A: Yes. The CDEP105NP-3R2MC-88 is electrically and mechanically equivalent to the CDEP105-3R2MC-88. All critical parameters including inductance value, current rating, DC resistance, core material, shielding, and physical dimensions are identical. The parts are interchangeable at the circuit level.

Q: What is the significance of the "NP" designation in the substitute part number?

A: The "NP" designation in CDEP105NP-3R2MC-88 indicates a packaging format difference. This part is supplied in Tape & Reel (TR) format, which is the standard packaging for automated surface mount assembly. The main part CDEP105-3R2MC-88 is supplied in bulk format.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance is a regulatory and material composition classification, not an electrical performance specification. Both parts meet identical electrical and thermal performance requirements. The ROHS3 compliance of the substitute part indicates it meets current environmental regulations for lead and restricted substance content.

Q: Are the physical footprints identical between these two parts?

A: Yes. Both parts share identical physical dimensions of 10.00 mm length × 10.00 mm width × 5.60 mm maximum height. The nonstandard package footprint is consistent across both parts, ensuring PCB layout compatibility.

Q: What is the moisture sensitivity level for these inductors?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly.

Q: Can these parts be used in high-temperature applications?

A: Yes. Both parts are rated for continuous operation across the temperature range of -40°C to 125°C, making them suitable for industrial and automotive applications requiring extended temperature performance.

Q: What is the inductance tolerance, and how does it affect circuit design?

A: Both parts have an inductance tolerance of ±20% at the 100 kHz test frequency. Circuit designs must account for this tolerance range when calculating filter response, impedance matching, or resonant frequency characteristics.

Q: Are there any supply chain advantages to using the substitute part?

A: Yes. The CDEP105NP-3R2MC-88 maintains active product status with current manufacturing availability, whereas the main part is obsolete. Using the substitute part ensures reliable long-term supply for production and maintenance requirements.
