Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSD0910B-100M is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Inductance value of 10 µH with ±20% tolerance
• Current rating of 5 A minimum
• Saturation current (Isat) of 5.6 A or greater
• DC resistance not exceeding 18.7 mOhm

Mechanical & Physical Requirements:

• Surface mount 4-SMD package configuration
• Nonstandard package case type
• Physical dimensions of 10.00 mm L x 9.00 mm W x 10.00 mm H
• Shielded wirewound construction with ferrite core

Compliance & Environmental:

• AEC-Q200 automotive qualification
• Operating temperature range of -40°C to 125°C
• ROHS3 compliance
• MSL rating of 1 or better

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes for the CSD0910B-100M.

Parameter Comparison

Engineering Selection Recommendations

The CSD0910B-100M is an active product with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection of substitute components for this inductor must maintain equivalence across all electrical parameters, physical dimensions, and compliance certifications.

The part's shielded wirewound construction with ferrite core and 18.7 mOhm maximum DC resistance are critical for high current power applications. The 5 A current rating with 5.6 A saturation current provides defined operating margins for circuit design.

Surface mount 4-SMD package configuration and nonstandard case dimensions are fixed mechanical requirements. Any substitute must match these specifications exactly to ensure compatibility with existing PCB layouts and assembly processes.

The -40°C to 125°C operating temperature range and MSL 1 rating indicate suitability for automotive and industrial environments without moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the CSD0910B-100M?

A: A valid substitute must match all electrical specifications (10 µH inductance, 5 A current rating, 5.6 A Isat, 18.7 mOhm max DCR), physical dimensions (10.00 mm x 9.00 mm x 10.00 mm), package type (4-SMD Nonstandard), and compliance certifications (AEC-Q200, ROHS3). The core material must be ferrite with shielded wirewound construction.

Q: Can I use a different inductance value as a substitute?

A: No. The inductance value of 10 µH is a critical electrical parameter. Substitutes must maintain this exact value within the ±20% tolerance specification. Different inductance values will alter circuit performance and are not acceptable substitutes.

Q: Are there current rating considerations for substitution?

A: Yes. The substitute must have a current rating of 5 A or greater and a saturation current (Isat) of 5.6 A or higher. Lower current ratings will not provide adequate performance margin for the intended application.

Q: Does the DC resistance specification affect substitution eligibility?

A: Yes. The maximum DC resistance of 18.7 mOhm is a specified parameter. Substitute parts must not exceed this value. Higher DC resistance will increase power dissipation and heat generation in the circuit.

Q: Is the nonstandard package dimension critical for substitution?

A: Yes. The 10.00 mm L x 9.00 mm W x 10.00 mm H dimensions are fixed mechanical requirements. Substitutes must match these exact dimensions to ensure PCB layout compatibility and assembly process compatibility.

Q: What is the significance of the AEC-Q200 rating?

A: AEC-Q200 is an automotive-grade qualification indicating the component meets automotive reliability and performance standards. Substitutes must maintain this certification to ensure suitability for automotive applications.

Q: Does RoHS3 compliance affect substitute selection?

A: Yes. The CSD0910B-100M is ROHS3 compliant. Substitutes must also be ROHS3 compliant to meet regulatory and environmental requirements.

Q: What does MSL 1 rating mean for storage and handling?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life with no moisture sensitivity constraints. Substitutes must maintain this MSL 1 rating to ensure no additional moisture control measures are required during storage or assembly.

Q: Can I substitute with a part from a different manufacturer?

A: Substitution is based on matching all electrical, mechanical, and compliance parameters. Parts from different manufacturers may be acceptable if they meet all specified criteria. However, only parts explicitly listed as parametric equivalents should be used.

Q: What is the operating temperature range significance?

A: The -40°C to 125°C operating temperature range defines the component's functional limits. Substitutes must support this same temperature range to ensure reliable operation across the intended application environment.
