Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD105NP-120MC is based on strict electrical and mechanical parameter matching. The following criteria determine valid substitutes:

Primary Matching Criteria:

• Inductance value: 12 µH with ±20% tolerance
• Current rating: 2.45 A minimum
• DC resistance: 70 mOhm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Surface Mount
• RoHS3 compliance requirement

Secondary Compatibility Factors:

• Operating temperature range must encompass or exceed -40°C to 100°C
• Moisture sensitivity level: 1 (Unlimited)
• Package classification: Nonstandard
• Packaging format: Tape & Reel (TR)

The SDR1006-120ML from Bourns Inc. meets all primary electrical matching criteria and maintains compatibility with the specified environmental and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the CD105NP-120MC and SDR1006-120ML are active products with ROHS3 compliance and unlimited moisture sensitivity rating, making them suitable for equivalent applications. The SDR1006-120ML provides an extended operating temperature range of -40°C to 125°C compared to the CD105NP-120MC range of -40°C to 100°C. This extended temperature capability offers additional thermal margin for applications operating near the upper temperature limit.

Selection between these parts should be based on:

• Supply availability: CD105NP-120MC has 1129 units in stock; SDR1006-120ML has 2722 units in stock
• Thermal requirements: SDR1006-120ML supports higher maximum operating temperature
• Manufacturer preference: Sumida America Components Inc. versus Bourns Inc.
• Mechanical fit: Both use nonstandard packages with identical seated height (5.80 mm maximum); dimensional differences are minimal (10.00 mm × 9.00 mm versus 9.80 mm × 9.80 mm)

Both parts satisfy the core electrical specifications and compliance requirements for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the SDR1006-120ML replace the CD105NP-120MC in all applications?

A: Yes, the SDR1006-120ML meets all specified electrical parameters: 12 µH inductance, 2.45 A current rating, and 70 mOhm maximum DC resistance. Both parts are unshielded ferrite core inductors with identical tolerance and RoHS3 compliance. The extended operating temperature range of the SDR1006-120ML (to 125°C) provides additional thermal capability.

Q: Are there physical compatibility concerns between these parts?

A: Both inductors use nonstandard packages with identical maximum seated height of 5.80 mm. Footprint dimensions differ slightly: CD105NP-120MC is 10.00 mm × 9.00 mm, while SDR1006-120ML is 9.80 mm × 9.80 mm. PCB layout verification is recommended for space-constrained designs.

Q: What is the significance of the ±20% inductance tolerance?

A: The ±20% tolerance indicates that actual inductance values may range from 9.6 µH to 14.4 µH. Both the CD105NP-120MC and SDR1006-120ML share this tolerance specification, ensuring equivalent performance variation in circuit applications.

Q: Do these parts have different saturation current characteristics?

A: The CD105NP-120MC does not specify saturation current (Isat). The SDR1006-120ML specifies Isat of 4.5 A, which exceeds the 2.45 A rated current. For applications requiring saturation current data, the SDR1006-120ML provides this specification.

Q: Are both parts available in Tape & Reel packaging?

A: Yes, both the CD105NP-120MC and SDR1006-120ML are supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. Both are classified under ECCN EAR99 and HTSUS 8504.50.4000.
