CD75NP-331KC Equivalent & Substitute Parts

Part Overview

The CD75NP-331KC is a 330 µH unshielded surface mount inductor manufactured by Sumida America Components Inc. This component is designed for applications requiring fixed inductance with a 400 mA current rating and 1.26 Ohm maximum DC resistance. The part operates across the temperature range of -40°C to 100°C and is classified as Active product status with ROHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required for design flexibility, supply chain continuity, or inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD75NP-331KC is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value: 330 µH at 1 kHz test frequency
• Inductance tolerance: ±10%
• Current rating: 400 mA minimum
• DC resistance: 1.26 Ohm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded

Mechanical Compatibility Requirements:

• Mounting type: Surface Mount
• Package classification: Nonstandard
• Physical dimensions compatible with PCB layout constraints

Compliance Requirements:

• RoHS3 compliance mandatory
• Moisture Sensitivity Level: 1 (Unlimited)

The SDR0805-331KL manufactured by Bourns Inc. meets all specified electrical and mechanical parameters, enabling direct substitution in applications where the CD75NP-331KC is designated.

Parameter Comparison

Engineering Selection Recommendations

Both the CD75NP-331KC and SDR0805-331KL are Active product status components with full ROHS3 compliance and identical moisture sensitivity ratings. Selection between these parts is based on availability, supply chain requirements, and inventory management rather than electrical or mechanical performance differences.

The SDR0805-331KL provides an extended operating temperature range to 125°C compared to the CD75NP-331KC maximum of 100°C. This extended range does not restrict substitution in applications operating within the CD75NP-331KC specification limits.

Both components are packaged in Tape & Reel format suitable for automated assembly processes. Physical dimensions are compatible with standard PCB layout requirements for nonstandard surface mount packages.

Frequently Asked Questions (FAQ)

Q: Can the SDR0805-331KL replace the CD75NP-331KC in all applications?

A: Yes. The SDR0805-331KL meets or exceeds all electrical and mechanical specifications of the CD75NP-331KC. Both components share identical inductance values, current ratings, DC resistance, core material, and shielding configuration. Both are ROHS3 compliant with unlimited moisture sensitivity ratings.

Q: What are the physical dimension differences between these parts?

A: The CD75NP-331KC measures 0.307" L x 0.276" W x 0.217" H (7.80mm x 7.00mm x 5.50mm). The SDR0805-331KL measures 0.307" L x 0.307" W x 0.209" H (7.80mm x 7.80mm x 5.30mm). Width and height differences are minimal and compatible with standard nonstandard surface mount PCB footprints.

Q: Are there temperature range considerations for substitution?

A: The SDR0805-331KL operates to 125°C versus the CD75NP-331KC maximum of 100°C. For applications within the -40°C to 100°C range, both parts are functionally equivalent. Applications requiring operation above 100°C must use the SDR0805-331KL.

Q: Do both parts use the same core material?

A: Yes. Both the CD75NP-331KC and SDR0805-331KL use ferrite core material in unshielded configuration, ensuring equivalent magnetic performance and inductance stability.

Q: What is the packaging format for both parts?

A: Both components are supplied in Tape & Reel (TR) format suitable for automated pick-and-place assembly. Moisture Sensitivity Level 1 (Unlimited) requires no special storage or handling precautions.
