CSBL1275-3R3M Equivalent & Substitute Parts

Part Overview

The CSBL1275-3R3M is a high Q value surface mount power inductor manufactured by CODACA. This shielded wirewound inductor is designed for applications requiring 3.3 µH inductance with a 22 A current rating and minimal DC resistance of 3.1 mOhm maximum. The component features a metal composite core with flat wire construction and is housed in a nonstandard package measuring 13.80mm × 12.80mm × 7.60mm (seated height).

The part maintains Active product status and carries AEC-Q200 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1). Identifying equivalent and substitute components is essential for supply chain continuity, design flexibility, and procurement optimization when the primary part becomes unavailable or when alternative sourcing is required.

Parameter Comparison

Engineering Selection Recommendations

The CSBL1275-3R3M maintains Active product status with full AEC-Q200 automotive qualification and ROHS3 compliance certification. The parametric equivalent CSBL1275-3R3M demonstrates identical electrical, mechanical, and compliance characteristics across all specified parameters.

Selection between the main part and its parametric equivalent is based on availability and procurement logistics rather than technical differentiation. Both components satisfy identical design requirements for 3.3 µH shielded wirewound power inductor applications with 22 A current handling capability.

Compliance certifications including AEC-Q200 automotive qualification and ROHS3 status are maintained across all equivalent parts, ensuring suitability for regulated applications and environmental standards compliance.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the CSBL1275-3R3M?

A: A valid substitute must match all specified parameters including 3.3 µH inductance at ±20% tolerance, 22 A current rating, 30 A saturation current, 3.1 mOhm maximum DC resistance, metal composite core material, shielded construction, -50°C to 150°C operating temperature range, surface mount configuration, 13.80 × 12.80 × 7.60 mm package dimensions, and 100 kHz inductance test frequency. The substitute must also maintain AEC-Q200 qualification, ROHS3 compliance, and Tape & Reel packaging format.

Q: Are there any parametric equivalents available for the CSBL1275-3R3M?

A: The CSBL1275-3R3M is identified as a parametric equivalent to itself, indicating that this part number represents the current available option meeting all specified electrical and mechanical requirements. No alternative part numbers with differing specifications are provided in the current substitute list.

Q: Can components with different package dimensions be used as substitutes?

A: No. Package dimensions of 13.80mm × 12.80mm × 7.60mm (seated height) are mandatory for mechanical compatibility with circuit board layouts and assembly processes. Substitutes with different dimensions are not acceptable.

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

A: AEC-Q200 certification indicates that the CSBL1275-3R3M meets automotive-grade reliability and performance standards. Substitutes must maintain this qualification to ensure suitability for automotive and similarly demanding applications.

Q: Does the ROHS3 compliance status affect substitute selection?

A: Yes. ROHS3 compliance is a mandatory requirement for substitutes. All equivalent parts must demonstrate ROHS3 compliance to meet environmental and regulatory standards applicable to the original component.

Q: What is the importance of the metal composite core material specification?

A: The metal composite core material directly influences the inductor's electrical performance characteristics including Q value, saturation behavior, and frequency response. Substitutes must use identical core material to maintain equivalent performance in the target application.

Q: Is the flat wire construction a critical specification for substitution?

A: Yes. The flat wire construction contributes to the high Q value characteristic and thermal performance of the CSBL1275-3R3M. Substitutes must incorporate flat wire design to maintain electrical and thermal equivalence.

Q: Can the CSBL1275-3R3M be used in applications requiring lower current ratings?

A: Yes. The 22 A current rating represents the maximum continuous current capacity. The component is suitable for applications requiring lower current levels, provided all other electrical parameters remain within specified ranges.

Q: What does the ±20% inductance tolerance mean for circuit design?

A: The ±20% tolerance indicates that actual inductance values may range from 2.64 µH to 3.96 µH. Circuit designs must account for this tolerance range to ensure proper operation across the full specification window.

Q: Is the Tape & Reel packaging format interchangeable with other packaging options?

A: No. Tape & Reel packaging is specified for automated assembly processes. Substitutes must be supplied in Tape & Reel format to maintain compatibility with production equipment and handling procedures.
