Substitute Part Grouping Explanation

Substitution of the CSBX1050-100M is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value of 10 µH with tolerance of ±20%
• Current rating minimum of 7.1 A
• Saturation current (Isat) minimum of 10.2 A
• DC resistance (DCR) not exceeding 18.9 mOhm

Mechanical Parameters:

• Surface mount wirewound construction with metal composite core
• Shielded configuration
• Package dimensions of 11.20 mm length × 10.20 mm width × 5.00 mm height maximum
• Nonstandard package case classification

Environmental & Compliance Parameters:

• Operating temperature range of -40°C to 125°C
• RoHS3 compliance
• AEC-Q200 automotive qualification
• Tape & Reel packaging format

Parts meeting all specified parameters within stated tolerances are classified as direct parametric equivalents. No deviations from these criteria are permitted for substitution classification.

Engineering Selection Recommendations

The CSBX1050-100M maintains Active product status with full AEC-Q200 automotive qualification and ROHS3 compliance, confirming suitability for current and future production applications. The parametric equivalent identified in this reference maintains identical electrical, mechanical, and environmental specifications, ensuring direct functional interchangeability without circuit redesign or performance degradation.

Selection of substitute components should be limited to parts meeting all specified parameters. The 10 µH inductance value with ±20% tolerance, 7.1 A current rating, and 10.2 A saturation current define the functional requirements. The metal composite shielded core construction and surface mount nonstandard package dimensions establish the mechanical constraints. Operating temperature range of -40°C to 125°C and compliance certifications (RoHS3, AEC-Q200) establish the environmental and regulatory boundaries for substitution.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the CSBX1050-100M?

A: A valid substitute must match all electrical parameters (10 µH inductance, 7.1 A current rating, 10.2 A saturation current, 18.9 mOhm maximum DCR), core material (metal composite), shielding configuration, mechanical dimensions (11.20 × 10.20 × 5.00 mm), operating temperature range (-40°C to 125°C), and compliance certifications (RoHS3, AEC-Q200).

Q: Can inductors with different saturation current ratings be substituted?

A: No. The saturation current of 10.2 A is a critical parameter. Substitutes must meet or exceed this specification to maintain circuit performance under peak current conditions.

Q: Are unshielded inductors acceptable as substitutes?

A: No. The CSBX1050-100M is specified as shielded. Unshielded inductors do not meet the substitution criteria and may introduce electromagnetic interference in the circuit.

Q: What is the significance of the metal composite core material?

A: The metal composite core material directly affects inductance stability, saturation characteristics, and thermal performance. Substitutes must use identical core material to maintain specified electrical performance.

Q: Can the package dimensions vary for surface mount compatibility?

A: No. The nonstandard package dimensions of 11.20 mm length × 10.20 mm width × 5.00 mm height are fixed substitution criteria. Dimensional variations will affect PCB layout and mechanical fit.

Q: Is the Tape & Reel packaging format mandatory for substitution?

A: Yes. The specified packaging format ensures compatibility with automated assembly processes. Alternative packaging formats do not meet the substitution criteria.

Q: What compliance certifications are required for substitutes?

A: Substitutes must maintain RoHS3 compliance and AEC-Q200 automotive qualification. These certifications confirm environmental and reliability standards for the application.

Q: Can the inductance tolerance of ±20% be exceeded in a substitute?

A: No. The ±20% tolerance is a specified parameter. Substitutes must maintain this tolerance band to ensure circuit performance within design specifications.
