Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDR105-680MC is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Inductance value: 68 µH
• Inductance tolerance: -15%, +20%
• Current rating: 970 mA minimum
• DC resistance: 220 mOhm maximum
• Shielding type: Shielded
• Self-resonant frequency: 11 MHz
• Mounting type: Surface Mount
• Physical dimensions: 10.00 mm L × 9.20 mm W × 5.50 mm H (max seated height)

The substitute part CDR105NP-680MC meets all mandatory electrical and mechanical parameters. This part is from the same manufacturer series (CDR105) and maintains identical inductance, current rating, DC resistance, shielding characteristics, and physical footprint. The primary distinction is product status and packaging configuration.

Engineering Selection Recommendations

CDR105NP-680MC as Primary Substitute:

The CDR105NP-680MC is the direct equivalent substitute for the obsolete CDR105-680MC. This part maintains complete electrical and mechanical compatibility across all critical parameters: inductance value, tolerance, current rating, DC resistance, shielding, frequency characteristics, and physical dimensions.

Compliance Advantages:

The CDR105NP-680MC offers improved regulatory compliance. It is ROHS3 compliant, whereas the original CDR105-680MC is RoHS non-compliant. For new designs or production revisions subject to RoHS requirements, the CDR105NP-680MC satisfies regulatory mandates without electrical or mechanical compromise.

Operating Temperature Consideration:

The CDR105NP-680MC extends the operating temperature range to -40°C to 100°C, compared to the original -25°C to 70°C specification. This extended range provides additional thermal margin for applications operating at temperature extremes, though both parts are functionally equivalent within the original part's temperature specification.

Packaging Configuration:

The CDR105NP-680MC is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original CDR105-680MC was supplied in bulk packaging. Packaging selection depends on production methodology and inventory management requirements.

Product Status:

The CDR105NP-680MC maintains active product status with current manufacturer support and availability. The CDR105-680MC is obsolete. For new production or long-term supply assurance, the CDR105NP-680MC is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Can CDR105NP-680MC be used as a direct replacement for CDR105-680MC in existing designs?

A: Yes. The CDR105NP-680MC is electrically and mechanically equivalent to the CDR105-680MC across all critical parameters: inductance (68 µH), tolerance (-15%, +20%), current rating (970 mA), DC resistance (220 mOhm max), shielding, frequency characteristics, and physical dimensions (10.00 × 9.20 × 5.50 mm). No circuit modifications are required.

Q: What is the difference between the two parts?

A: The primary differences are: (1) Product Status—CDR105NP-680MC is active; CDR105-680MC is obsolete. (2) RoHS Compliance—CDR105NP-680MC is ROHS3 compliant; CDR105-680MC is non-compliant. (3) Operating Temperature—CDR105NP-680MC operates -40°C to 100°C; CDR105-680MC operates -25°C to 70°C. (4) Packaging—CDR105NP-680MC is supplied in Tape & Reel; CDR105-680MC was supplied in bulk.

Q: Are there any electrical performance differences?

A: No. Both parts are specified with identical inductance, tolerance, current rating, DC resistance, self-resonant frequency, and test frequency. Electrical performance is equivalent.

Q: Is the physical footprint identical?

A: Yes. Both parts have identical dimensions: 10.00 mm length × 9.20 mm width × 5.50 mm maximum seated height. PCB layout and mechanical mounting are identical.

Q: Which part should be selected for new designs?

A: CDR105NP-680MC is the recommended selection for new designs. It is an active product with current manufacturer support, ROHS3 compliance, and extended operating temperature range. The CDR105-680MC is obsolete and should not be specified for new production.

Q: Can CDR105NP-680MC be used in applications requiring the original -25°C to 70°C temperature range?

A: Yes. The CDR105NP-680MC operating range of -40°C to 100°C fully encompasses the original -25°C to 70°C specification. It is suitable for all applications within the original temperature range and provides additional thermal margin.

Q: What packaging format is appropriate for my production process?

A: CDR105NP-680MC is supplied in Tape & Reel (TR) packaging, optimized for automated pick-and-place assembly. If bulk packaging is required, consult with the manufacturer regarding alternative packaging options or consider reel-to-bulk conversion services.

Q: Is the Moisture Sensitivity Level the same?

A: Yes. Both parts are specified with MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
