Substitute Part Grouping Explanation

Substitute parts for the CDR105-390MC are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

• Inductance value: 39 µH
• Inductance tolerance: -15%, +20%
• Current rating: 1.28 A
• DC resistance: 160mOhm maximum
• Self-resonant frequency: 15 MHz
• Inductance test frequency: 2.52 MHz

Mechanical Parameters (Must Match):

• Shielding type: Shielded
• Mounting type: Surface Mount
• Package type: Nonstandard
• 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-390MC meets all these criteria and qualifies as a direct substitute. The primary distinction is product status and packaging configuration.

Engineering Selection Recommendations

The CDR105NP-390MC is the qualified substitute for the obsolete CDR105-390MC. Selection of the substitute part is based on the following engineering factors:

Product Status: The CDR105-390MC is classified as obsolete. The CDR105NP-390MC is active and available in production quantities, making it the appropriate choice for new designs and ongoing production support.

Electrical Compatibility: All critical electrical parameters are identical between the main part and substitute, including inductance value, tolerance, current rating, DC resistance, and self-resonant frequency. Direct electrical substitution is supported.

Mechanical Compatibility: Physical dimensions, mounting type, and package configuration are identical. The substitute part fits existing PCB layouts and assembly processes without modification.

Compliance Status: The CDR105NP-390MC is ROHS3 compliant, whereas the main part is RoHS non-compliant. For applications subject to RoHS regulations, the substitute part satisfies compliance requirements.

Operating Temperature Range: The substitute part operates across -40°C to 100°C, which encompasses the main part's -25°C to 70°C range. The wider operating temperature range of the substitute provides additional design margin.

Packaging: The substitute is supplied in Tape & Reel (TR) format, which is standard for automated assembly operations. This represents an improvement over the main part's unspecified packaging.

Inventory Availability: The CDR105NP-390MC is available in production quantities (751 Pcs New Original In Stock), ensuring supply continuity for manufacturing operations.
