CSBL0650-100M Equivalent & Substitute Parts

Part Overview

The CSBL0650-100M is a high Q value surface mount power inductor manufactured by CODACA. This shielded wirewound inductor is rated for 10 µH inductance with a maximum DC resistance of 30.5 mOhm and supports continuous current operation up to 4.4 A. The component is housed in a nonstandard surface mount package measuring 7.00mm × 6.90mm × 5.00mm (max height) and is qualified to AEC-Q200 automotive standards. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified based on matching electrical specifications, mechanical dimensions, and compliance certifications to ensure direct functional equivalence in circuit applications.

Substitute Part Grouping Explanation

Substitute parts for the CSBL0650-100M are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must align with the main part specification:

Electrical Parameters:

• Inductance value of 10 µH with ±20% tolerance
• Current rating of 4.4 A continuous operation
• Saturation current (Isat) of 6 A
• DC resistance not exceeding 30.5 mOhm

Mechanical Parameters:

• Surface mount wirewound construction
• Metal composite core material with shielding
• Package dimensions of 7.00mm × 6.90mm × 5.00mm (max height)
• Nonstandard package classification

Compliance & Environmental Parameters:

• AEC-Q200 automotive qualification
• Operating temperature range of -50°C to 150°C
• RoHS3 compliance
• MSL 1 rating (unlimited moisture sensitivity)
• Inductance measurement at 100 kHz test frequency

Parts meeting all specified parameters within the defined tolerances are classified as direct parametric equivalents and may be substituted without circuit redesign or performance degradation.

Engineering Selection Recommendations

The CSBL0650-100M maintains active product status with full AEC-Q200 automotive qualification and RoHS3 compliance. When selecting substitute components, the following engineering criteria apply:

Compliance Verification: All substitute parts must maintain AEC-Q200 qualification to ensure suitability for automotive and high-reliability applications. RoHS3 compliance is mandatory for supply chain continuity and regulatory adherence.

Electrical Specification Matching: Substitute inductors must deliver the specified 10 µH inductance value within the ±20% tolerance band when measured at 100 kHz. The 4.4 A continuous current rating and 6 A saturation current specification must be met without exception. DC resistance must not exceed the 30.5 mOhm maximum to prevent thermal performance degradation in power delivery circuits.

Mechanical and Thermal Compatibility: The nonstandard surface mount package dimensions of 7.00mm × 6.90mm × 5.00mm (max height) must be maintained for PCB layout compatibility. The -50°C to 150°C operating temperature range must be supported to ensure performance across automotive environmental conditions.

Material and Construction Requirements: Substitute parts must employ metal composite core construction with shielding to maintain electromagnetic compatibility and minimize radiated emissions. Wirewound construction type is required for the specified Q value performance.

Moisture and Environmental Handling: MSL 1 rating (unlimited moisture sensitivity) eliminates moisture-related handling constraints and simplifies supply chain logistics.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the CSBL0650-100M?

A: A valid substitute must match all critical electrical parameters (10 µH inductance at ±20% tolerance, 4.4 A current rating, 6 A saturation current, 30.5 mOhm max DC resistance), maintain identical mechanical dimensions (7.00mm × 6.90mm × 5.00mm), employ metal composite shielded wirewound construction, operate across -50°C to 150°C, and hold AEC-Q200 qualification with RoHS3 compliance.

Q: Can inductors with different DC resistance values substitute for the CSBL0650-100M?

A: No. The 30.5 mOhm maximum DC resistance specification is a critical parameter. Higher DC resistance increases power dissipation and thermal generation in the inductor, degrading circuit efficiency and potentially causing thermal runaway in power delivery applications. Substitute parts must not exceed this specification.

Q: Are there packaging format alternatives for this inductor?

A: The CSBL0650-100M is specified in Tape & Reel (TR) packaging format. Substitute parts must maintain this packaging format for automated assembly compatibility. The nonstandard package dimensions (7.00mm × 6.90mm × 5.00mm) are fixed and cannot be altered without requiring PCB redesign.

Q: What is the significance of AEC-Q200 qualification for this part?

A: AEC-Q200 qualification certifies the inductor for automotive-grade reliability and performance under demanding environmental and electrical stress conditions. This qualification is mandatory for automotive applications and high-reliability systems. Substitute parts must maintain this certification to ensure equivalent reliability and supply chain acceptance.

Q: Does the ±20% inductance tolerance affect circuit design?

A: The ±20% tolerance is the specified manufacturing tolerance for this inductor series. Circuit designs using the CSBL0650-100M must account for this tolerance band in inductance value. Substitute parts with identical ±20% tolerance maintain design compatibility without requiring circuit recalculation.

Q: What is the importance of the 100 kHz inductance test frequency specification?

A: The 10 µH inductance value is measured and guaranteed at 100 kHz. This test frequency is standard for power inductor characterization and reflects typical switching frequencies in modern power conversion circuits. Substitute parts must be characterized at the same 100 kHz test frequency to ensure specification equivalence.

Q: Can this inductor be used in applications exceeding the 4.4 A continuous current rating?

A: No. The 4.4 A specification is the maximum continuous current rating. Operation above this level causes excessive heating and potential inductor failure. The 6 A saturation current specification indicates the current level at which the inductor begins to lose inductance due to core saturation; this is not an operating point but a performance boundary.

Q: Is the MSL 1 rating significant for component handling?

A: MSL 1 (unlimited moisture sensitivity) indicates the component has no moisture absorption constraints. This eliminates the need for moisture-controlled storage, desiccant packaging, or bake-out procedures before soldering. This simplifies supply chain handling and reduces component preparation time.
