Substitute Part Grouping Explanation

Substitute parts for the CSBX0640-4R7M are identified through parametric equivalence matching. The critical electrical parameters that define substitution eligibility include inductance value (4.7 µH), inductance tolerance (±20%), current rating (6.4 A), saturation current (11 A), and DC resistance (21.2 mOhm maximum). Mechanical compatibility is established through matching mounting type (Surface Mount), package classification (Nonstandard), and physical dimensions (0.276" L x 0.272" W, 4.00 mm maximum height). Construction parameters including wirewound type, metal composite core material, and shielded configuration must remain consistent. Environmental and compliance parameters—operating temperature range (-40°C to 125°C), AEC-Q200 rating, RoHS3 compliance, and REACH unaffected status—ensure functional equivalence in regulated applications. Packaging format (Tape & Reel) and product status (Active) confirm availability and supply chain compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CSBX0640-4R7M maintains Active product status with full AEC-Q200 automotive qualification, ensuring suitability for regulated applications requiring high reliability standards. The component carries ROHS3 compliance and REACH unaffected status, meeting environmental and regulatory requirements for industrial and automotive markets. The Moisture Sensitivity Level of 1 (Unlimited) indicates no moisture-related handling restrictions during assembly and storage. Surface mount construction with nonstandard package dimensions requires verification of PCB layout compatibility and assembly equipment capability. The high saturation feature and metal composite core material provide stable inductance performance across the specified current range. Selection of substitute parts should prioritize matching all electrical parameters, mechanical dimensions, and compliance certifications to maintain circuit performance and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for a part to be considered a substitute for the CSBX0640-4R7M?

A: The inductance value (4.7 µH), inductance tolerance (±20%), current rating (6.4 A), saturation current (11 A), and DC resistance (21.2 mOhm maximum) must all match exactly. These parameters directly determine circuit performance and thermal behavior.

Q: Are there mechanical compatibility requirements for substitution?

A: Yes. The mounting type (Surface Mount), package classification (Nonstandard), and physical dimensions (0.276" L x 0.272" W with 4.00 mm maximum height) must match to ensure PCB footprint compatibility and assembly feasibility.

Q: What construction specifications are critical for substitution?

A: The wirewound type, metal composite core material, and shielded configuration must remain consistent. These specifications define electromagnetic performance and EMI characteristics in the circuit.

Q: Does the operating temperature range affect substitution eligibility?

A: Yes. The operating temperature range of -40°C to 125°C must be maintained. Substitutes with different temperature ratings are not functionally equivalent for applications requiring this thermal specification.

Q: What compliance certifications must substitute parts maintain?

A: Substitute parts must carry AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status. These certifications are mandatory for regulated applications and cannot be compromised.

Q: Is the Moisture Sensitivity Level (MSL) important for substitution?

A: Yes. The MSL rating of 1 (Unlimited) indicates no moisture-related handling restrictions. Substitute parts must maintain this MSL classification to ensure identical storage and assembly requirements.

Q: Can the packaging format be changed when selecting a substitute?

A: No. The Tape & Reel (TR) packaging format must be maintained to ensure supply chain compatibility and automated assembly capability.

Q: What role does the inductance test frequency play in substitution?

A: The 100 kHz test frequency is the standard measurement condition for this component class. Substitute parts must be characterized at the same frequency to ensure accurate inductance value comparison.

Q: Does product status affect the substitution decision?

A: Yes. Both the main part and substitute must maintain Active product status to ensure long-term availability and supply chain continuity.

Q: Are there any frequency-dependent parameters that affect substitution?

A: The self-resonant frequency and Q factor at frequency are not specified in the provided data. Substitution decisions are based on the parameters explicitly provided: inductance, current ratings, DC resistance, and mechanical specifications.
