Substitute Part Grouping Explanation

Substitution of the CSBL1809-100M SMD power inductor is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Inductance value of 10 µH with ±20% tolerance
• Current rating of 16 A minimum
• Saturation current (Isat) of 24 A minimum
• DC resistance (DCR) of 6.9 mOhm maximum

Mechanical Specifications:

• Surface mount wirewound construction with metal composite core
• Shielded design
• Nonstandard package dimensions: 0.760" L x 0.717" W (19.30 mm x 18.20 mm)
• Maximum seated height of 0.362" (9.20 mm)
• Flat wire construction

Compliance & Environmental:

• AEC-Q200 automotive rating
• Operating temperature range of -50°C to 150°C
• ROHS3 compliance
• Tape & Reel packaging format

Substitute parts must match all electrical parameters within specified tolerances, maintain identical mechanical dimensions and mounting characteristics, and retain all compliance certifications. Deviations in any critical parameter disqualify a part from substitution eligibility.

Engineering Selection Recommendations

The CSBL1809-100M maintains active product status with confirmed inventory availability of 1211 pieces. The component carries AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status, meeting regulatory requirements for automotive and industrial applications.

When selecting equivalent or substitute inductors for the CSBL1809-100M, prioritize parts that maintain identical electrical specifications: 10 µH inductance at ±20% tolerance, 16 A current rating, 24 A saturation current, and 6.9 mOhm maximum DC resistance. Mechanical compatibility requires matching the nonstandard package dimensions of 19.30 mm x 18.20 mm with maximum seated height of 9.20 mm.

Compliance certifications must remain consistent. Parts must retain AEC-Q200 automotive rating, ROHS3 compliance status, and REACH unaffected designation. Operating temperature range must span -50°C to 150°C minimum. Shielded wirewound construction with metal composite core and flat wire design are mandatory for functional equivalence.

Surface mount packaging in Tape & Reel format ensures compatibility with standard assembly processes. Parts meeting all specified parameters are direct substitutes requiring no circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the CSBL1809-100M inductor?

A: A valid substitute must match all electrical parameters: 10 µH inductance with ±20% tolerance, 16 A current rating, 24 A saturation current, and 6.9 mOhm maximum DC resistance. The substitute must also match mechanical dimensions (19.30 mm x 18.20 mm x 9.20 mm max height), maintain shielded wirewound construction with metal composite core, and retain AEC-Q200, ROHS3, and REACH compliance certifications.

Q: Can inductors with different DC resistance values substitute for the CSBL1809-100M?

A: No. The DC resistance specification of 6.9 mOhm maximum is a critical electrical parameter. Substitutes with higher DC resistance will increase power dissipation and heat generation. Substitutes with lower DC resistance may not be available from the same series and would require full electrical and thermal re-evaluation.

Q: Are there dimensional constraints for package substitution?

A: Yes. The CSBL1809-100M uses a nonstandard package with specific dimensions of 0.760" L x 0.717" W (19.30 mm x 18.20 mm) and maximum seated height of 0.362" (9.20 mm). Substitutes must match these dimensions exactly to ensure compatibility with PCB footprints and clearance requirements in the target application.

Q: Does the flat wire construction affect substitution eligibility?

A: Yes. The flat wire construction is a specified feature contributing to the high Q value characteristic of this inductor. Substitutes must retain flat wire design to maintain electrical performance and thermal characteristics. Standard round wire inductors are not equivalent.

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

A: AEC-Q200 certification indicates automotive-grade qualification with defined reliability and performance standards. Substitutes must maintain this certification to ensure compliance with automotive application requirements. Parts without AEC-Q200 rating are not suitable substitutes for automotive use cases.

Q: Can the CSBL1809-100M be substituted with inductors from different manufacturers?

A: Substitution across manufacturers is possible only when the alternative part meets all specified electrical, mechanical, and compliance parameters. The substitute must be from the same CSBL1809 series or an equivalent series with identical specifications. Cross-manufacturer substitution requires verification of all parameters against the provided specifications.

Q: What is the importance of the ±20% inductance tolerance in substitution?

A: The ±20% tolerance defines the acceptable inductance range (8 µH to 12 µH) for circuit operation. Substitutes must maintain this same tolerance specification. Parts with tighter or looser tolerances may not be functionally equivalent and could affect circuit performance or require design modifications.

Q: Does Tape & Reel packaging affect substitution compatibility?

A: Tape & Reel packaging is the specified format for this component. Substitutes must use identical packaging to ensure compatibility with automated assembly equipment and handling processes. Alternative packaging formats (bulk, tube, or tray) would require process changes and are not direct substitutes.

Q: What role does the operating temperature range play in substitution?

A: The -50°C to 150°C operating temperature range defines the thermal environment in which the inductor maintains specified electrical performance. Substitutes must support this full temperature range. Parts with narrower temperature ranges are not equivalent and may fail in extreme temperature conditions.

Q: Is the 100 kHz inductance test frequency a substitution criterion?

A: Yes. The inductance value of 10 µH is measured and specified at 100 kHz. Substitutes must have inductance measured at the same frequency to ensure accurate electrical equivalence. Inductance values measured at different frequencies may not be directly comparable.
