CSBL0650-4R7M Equivalent & Substitute Parts

Part Overview

The CSBL0650-4R7M is a high Q value surface mount power inductor manufactured by CODACA. This shielded wirewound inductor is rated for 6.5 A continuous current with a 4.7 µH inductance value and operates across an extended temperature range of -50°C to 150°C. The component is AEC-Q200 qualified and maintains active product status with full RoHS3 compliance.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when supply chain constraints occur, or when design flexibility is required across multiple procurement sources while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitute parts for the CSBL0650-4R7M must satisfy all critical electrical and mechanical parameters to ensure direct interchangeability without circuit redesign or performance degradation. The substitution logic is based strictly on the following parameters:

Electrical Parameters (Must Match Exactly):

• Inductance value: 4.7 µH
• Inductance tolerance: ±20%
• Current rating: 6.5 A minimum
• Saturation current (Isat): 9 A minimum
• DC resistance: 17 mOhm maximum

Mechanical Parameters (Must Match Exactly):

• Mounting type: Surface Mount
• Package dimensions: 7.00 mm L × 6.90 mm W × 5.00 mm H maximum
• Core material: Metal Composite
• Shielding: Shielded configuration

Compliance Parameters (Must Match Exactly):

• AEC-Q200 qualification
• RoHS3 compliance
• Operating temperature range: -50°C to 150°C minimum
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. No deviations from these specifications are permitted for substitute classification.

Engineering Selection Recommendations

The CSBL0650-4R7M maintains active product status with full AEC-Q200 automotive qualification and ROHS3 compliance. When selecting substitute parts, the following engineering criteria apply:

Product Status Consideration: The substitute part must maintain active product status to ensure ongoing availability and manufacturing consistency. Obsolete or discontinued parts do not qualify as substitutes.

Compliance Verification: All substitute parts must retain AEC-Q200 qualification for automotive-grade applications and maintain ROHS3 compliance for environmental and regulatory requirements. These certifications cannot be compromised in substitution decisions.

Electrical Performance: The substitute part must deliver identical electrical performance across the specified inductance value, current rating, and saturation characteristics. The 4.7 µH inductance with ±20% tolerance and 6.5 A continuous current rating are non-negotiable parameters.

Thermal and Environmental Stability: The operating temperature range of -50°C to 150°C and moisture sensitivity level MSL 1 (Unlimited) must be maintained to ensure reliability across all deployment environments.

Mechanical Compatibility: Surface mount package dimensions of 7.00 mm × 6.90 mm × 5.00 mm must be preserved to ensure PCB layout compatibility and assembly process alignment without design modifications.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the CSBL0650-4R7M?

A: A valid substitute must match all electrical parameters (4.7 µH inductance, ±20% tolerance, 6.5 A current rating, 9 A saturation current, 17 mOhm maximum DCR), mechanical specifications (7.00 × 6.90 × 5.00 mm surface mount package), core material (metal composite), shielding configuration, operating temperature range (-50°C to 150°C), and compliance certifications (AEC-Q200, ROHS3, MSL 1).

Q: Can I use a part with lower current rating as a substitute?

A: No. The current rating of 6.5 A is a critical electrical parameter. Any substitute must maintain or exceed this rating. Using a lower-rated part creates thermal stress and reliability risks.

Q: Are there any substitutes available from other manufacturers?

A: Based on the provided input parameters, only the CSBL0650-4R7M from CODACA is listed as a parametric equivalent. No cross-manufacturer substitutes are specified in the available data.

Q: Does the inductance tolerance affect substitution eligibility?

A: The ±20% tolerance is a specified parameter of the CSBL0650-4R7M. Substitute parts must maintain this identical tolerance. Parts with tighter or looser tolerances do not qualify as direct substitutes.

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

A: AEC-Q200 qualification indicates automotive-grade reliability and stress testing compliance. Substitute parts must retain this certification to maintain design integrity in automotive applications. Non-qualified parts are not acceptable substitutes.

Q: Can I substitute this inductor with a different package size?

A: No. The package dimensions of 7.00 mm × 6.90 mm × 5.00 mm are fixed mechanical parameters. Different package sizes will not fit the PCB layout and are not valid substitutes.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean for handling?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This specification must be maintained in any substitute part to preserve supply chain flexibility.

Q: Is the 17 mOhm maximum DC resistance a hard limit for substitutes?

A: Yes. The DC resistance directly affects power dissipation and thermal performance. Substitute parts must meet or exceed this specification. Higher resistance values will increase heat generation and are not acceptable.

Q: How does the metal composite core material affect substitution?

A: The metal composite core material is specified for this inductor's performance characteristics. Substitute parts must use identical core material to maintain inductance stability, Q factor, and frequency response across the operating temperature range.

Q: Can I use this part in applications outside the -50°C to 150°C temperature range?

A: No. The operating temperature range is a critical specification. Using the component outside this range voids the AEC-Q200 qualification and may cause performance degradation or failure.
