Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDR105-470MC is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Inductance value: 47 µH
• Inductance tolerance: -15%, +20%
• Current rating: 1.17 A
• DC resistance: 180mOhm maximum
• Self-resonant frequency: 14MHz
• Test frequency: 2.52 MHz

Mechanical Parameters (Must Match):

• Shielding type: Shielded
• Mounting type: Surface Mount
• Physical dimensions: 0.394" L x 0.362" W (10.00mm x 9.20mm)
• Maximum seated height: 0.217" (5.50mm)

Environmental Parameters (Must Match):

• Moisture sensitivity level: 1 (Unlimited)

The CDR105NP-470MC qualifies as a direct substitute based on identical electrical, mechanical, and environmental specifications. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The CDR105NP-470MC is the direct functional equivalent to the CDR105-470MC. Selection between these parts is determined by application requirements and regulatory compliance:

Use CDR105NP-470MC when:

• Active product availability is required for new production or ongoing supply
• ROHS3 compliance is mandated by design specifications or customer requirements
• Extended operating temperature range (-40°C to 100°C) is necessary for the application
• Tape & Reel packaging is compatible with assembly processes

Use CDR105-470MC when:

• Existing inventory stock is available and acceptable for the application
• RoHS non-compliance does not conflict with product requirements
• Operating temperature range of -25°C to 70°C is sufficient for the application
• Bulk packaging meets assembly requirements

Both parts maintain identical electrical performance, mechanical fit, and environmental handling characteristics. The choice between them is based on product lifecycle status, regulatory compliance obligations, and operational temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can CDR105NP-470MC be used as a direct replacement for CDR105-470MC in existing designs?

A: Yes. The CDR105NP-470MC is electrically and mechanically equivalent. All critical parameters including inductance, current rating, DC resistance, shielding, dimensions, and resonant frequency are identical. The primary differences are product status (active vs. obsolete), packaging format (Tape & Reel vs. bulk), operating temperature range, and RoHS compliance status.

Q: What is the difference in operating temperature range between these parts?

A: The CDR105-470MC operates from -25°C to 70°C, while the CDR105NP-470MC operates from -40°C to 100°C. The substitute part provides extended temperature capability at both lower and upper limits.

Q: Are there packaging differences between CDR105-470MC and CDR105NP-470MC?

A: Yes. The CDR105-470MC is supplied in bulk packaging, while the CDR105NP-470MC is supplied in Tape & Reel (TR) format. Both are surface mount components with identical physical dimensions and mounting characteristics.

Q: What is the RoHS compliance difference?

A: The CDR105-470MC is RoHS non-compliant. The CDR105NP-470MC is ROHS3 compliant. Applications requiring RoHS compliance must use the CDR105NP-470MC variant.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts have identical dimensions of 0.394" L x 0.362" W (10.00mm x 9.20mm) with a maximum seated height of 0.217" (5.50mm). They are mechanically interchangeable in PCB layouts.

Q: What inventory status should be considered when selecting between these parts?

A: The CDR105-470MC (obsolete) has 1048 pieces in stock. The CDR105NP-470MC (active) has 1142 pieces in stock. For long-term supply assurance, the active product status of CDR105NP-470MC is preferable.
