Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSBX0640-2R2M is determined by strict equivalence across the following critical parameters:

Inductance Value: 2.2 µH with ±20% tolerance establishes the primary functional requirement. Substitute parts must match this inductance specification exactly.

Current Ratings: Both the continuous current rating of 9 A and saturation current (Isat) of 16 A define the power handling capability. Substitute parts must meet or exceed these specifications.

DC Resistance: Maximum DCR of 12.1 mOhm establishes thermal and efficiency performance boundaries. Substitute parts must not exceed this value.

Core Material and Shielding: Metal composite core with shielding configuration is essential for electromagnetic performance and noise isolation. Substitute parts must maintain identical core material and shielding characteristics.

Physical Dimensions: The nonstandard package size of 0.276" L x 0.272" W (7.00mm x 6.90mm) with maximum seated height of 0.157" (4.00mm) is mandatory for mechanical fit in the target application.

Environmental and Compliance Ratings: AEC-Q200 qualification, operating temperature range of -40°C ~ 125°C, ROHS3 compliance, and REACH unaffected status are non-negotiable for automotive and industrial applications.

Mounting and Packaging: Surface mount configuration with Tape & Reel packaging must be preserved for assembly compatibility.

Engineering Selection Recommendations

The CSBX0640-2R2M maintains active product status with full manufacturing support and 2002 pieces in current inventory. This part carries AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status, making it suitable for automotive, industrial, and consumer applications requiring environmental and regulatory adherence.

When selecting equivalent or substitute inductors, prioritize parts that maintain identical electrical specifications (2.2 µH inductance, 9 A continuous current, 16 A saturation current, and 12.1 mOhm maximum DCR) and physical dimensions (7.00mm x 6.90mm x 4.00mm maximum height). The metal composite core with shielding is critical for applications requiring electromagnetic isolation and stable inductance across the operating temperature range of -40°C to 125°C.

Compliance certifications including AEC-Q200 qualification and ROHS3 status are mandatory for automotive and regulated industrial applications. The unlimited moisture sensitivity level (MSL 1) permits standard handling and storage without special precautions.

Frequently Asked Questions (FAQ)

Q: What makes the CSBX0640-2R2M suitable for high saturation applications?

A: The metal composite core material combined with the wirewound construction provides high saturation characteristics. The part achieves a saturation current (Isat) of 16 A while maintaining a continuous current rating of 9 A, enabling operation in circuits requiring controlled inductance under varying current conditions.

Q: Are there dimensional constraints when substituting this inductor?

A: Yes. The nonstandard package dimensions of 0.276" L x 0.272" W (7.00mm x 6.90mm) with a maximum seated height of 0.157" (4.00mm) are fixed. Any substitute part must match these dimensions exactly to ensure mechanical compatibility with the PCB layout and component placement.

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

A: The ±20% tolerance defines the acceptable inductance range from 1.76 µH to 2.64 µH. Circuit designs must account for this tolerance band. Substitute parts must maintain identical tolerance specifications to ensure equivalent circuit performance.

Q: Does the shielding configuration affect substitution?

A: Yes. The shielded wirewound construction is essential for electromagnetic performance and noise isolation. Substitute parts must maintain identical shielding to prevent electromagnetic interference and ensure stable inductance characteristics in the target application.

Q: What compliance certifications are critical for this part?

A: AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status are the primary certifications. These are mandatory for automotive and regulated industrial applications. Substitute parts must maintain identical certification status.

Q: How does the DC resistance specification impact part selection?

A: The maximum DCR of 12.1 mOhm directly affects thermal performance and power dissipation. Higher DCR values result in increased heat generation. Substitute parts must not exceed this DCR specification to maintain equivalent thermal characteristics and efficiency.

Q: Is the 100 kHz inductance test frequency important for substitution?

A: Yes. The inductance value of 2.2 µH is measured at 100 kHz. Substitute parts must be specified at the same test frequency to ensure accurate inductance comparison and circuit performance equivalence.

Q: What is the operating temperature range significance?

A: The -40°C to 125°C operating range defines the thermal environment in which the inductor maintains specified electrical characteristics. Substitute parts must support this identical temperature range for applications in automotive and industrial environments.

Q: Does the Tape & Reel packaging affect substitution decisions?

A: Yes. The Tape & Reel packaging is specified for automated assembly processes. Substitute parts must maintain identical packaging format to ensure compatibility with pick-and-place equipment and assembly workflows.

Q: What does MSL 1 (Unlimited) mean for handling and storage?

A: Moisture Sensitivity Level 1 indicates unlimited shelf life without special moisture control requirements. The part does not require dry-pack storage or baking procedures prior to assembly, simplifying inventory management and procurement logistics.
