Engineering Selection Recommendations

The CDR105NP-820MC is a direct functional equivalent to the CDR105-820MC across all critical electrical and mechanical parameters. Selection between these parts should be based on the following factors:

Product Status Consideration: The CDR105-820MC carries obsolete product status, which indicates discontinued manufacturing and limited availability. The CDR105NP-820MC maintains active product status with confirmed inventory of 1004 pieces, ensuring supply chain reliability for current and future production requirements.

Compliance & Certification: The CDR105NP-820MC is ROHS3 compliant, whereas the CDR105-820MC is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the CDR105NP-820MC is the appropriate selection.

Operating Temperature Range: The CDR105NP-820MC supports an extended operating temperature range of -40°C ~ 100°C compared to the CDR105-820MC range of -25°C ~ 70°C. Applications requiring operation at lower or higher temperature extremes benefit from the substitute part's expanded thermal envelope.

Packaging Format: The CDR105NP-820MC is supplied in Tape & Reel (TR) format, facilitating automated assembly processes. The main part packaging specification is not defined, which may impact production workflow compatibility.

Electrical Performance: Both parts maintain identical inductance (82 µH), current rating (880 mA), DC resistance (280 mOhm maximum), and frequency characteristics (10 MHz self-resonant, 2.52 MHz test frequency). No electrical performance degradation occurs with substitution.

Frequently Asked Questions (FAQ)

Q: Can CDR105NP-820MC be used as a direct replacement for CDR105-820MC in existing designs?

A: Yes. The CDR105NP-820MC meets all electrical specifications (82 µH inductance, 880 mA current rating, 280 mOhm DCR maximum) and mechanical specifications (surface mount, nonstandard package, 10.00 mm x 9.20 mm x 5.50 mm maximum height) of the CDR105-820MC. Physical footprint and electrical performance are identical.

Q: What is the primary reason to transition from CDR105-820MC to CDR105NP-820MC?

A: The CDR105-820MC is classified as obsolete product status with limited inventory availability. The CDR105NP-820MC is an active product with confirmed stock of 1004 pieces, ensuring supply continuity. Additionally, the substitute part is ROHS3 compliant and supports an extended operating temperature range (-40°C ~ 100°C versus -25°C ~ 70°C).

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

A: No. Both parts are specified with identical inductance tolerance (-15%, +20%), current rating (880 mA), DC resistance (280 mOhm maximum), shielding (shielded), self-resonant frequency (10 MHz), and test frequency (2.52 MHz). Electrical behavior in circuit operation is equivalent.

Q: Does the Tape & Reel packaging of CDR105NP-820MC affect compatibility?

A: Tape & Reel packaging is a supply format that facilitates automated pick-and-place assembly. It does not affect electrical or mechanical compatibility. The component itself maintains identical physical dimensions and mounting characteristics. Tape & Reel format is standard for surface mount production environments.

Q: What is the moisture sensitivity level for both parts?

A: Both CDR105-820MC and CDR105NP-820MC are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly.

Q: Are there any compliance or regulatory differences?

A: Yes. The CDR105NP-820MC is ROHS3 compliant, while the CDR105-820MC is RoHS non-compliant. For applications or markets requiring RoHS compliance, the substitute part is the appropriate selection. Both parts are classified as EAR99 for export control purposes and are REACH unaffected.
