CSHB0540R-4R7M Equivalent & Substitute Parts

Part Overview

The CSHB0540R-4R7M is a shielded molded inductor manufactured by CODACA, classified as a power choke for surface mount applications. This component features a 4.7 µH inductance rating with a 7 A current capacity and operates across the industrial temperature range of -40°C to 125°C. The part maintains Active product status and is RoHS3 compliant, making it suitable for modern electronic assemblies requiring regulated power distribution and EMI filtering.

Identifying equivalent and substitute parts is necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility permits selection from multiple qualified sources meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the CSHB0540R-4R7M is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Inductance value of 4.7 µH with ±20% tolerance
• Current rating of 7 A minimum
• Saturation current (Isat) of 7.5 A or greater
• DC resistance not exceeding 28.4 mOhm

Mechanical & Physical Requirements:

• Shielded construction
• Magnetic powder core material
• Molded inductor type
• Surface mount configuration
• Nonstandard package footprint matching 5.80 mm × 5.20 mm × 4.00 mm (Max height)

Environmental & Compliance Criteria:

• Operating temperature range of -40°C to 125°C or broader
• RoHS3 compliance
• MSL 1 rating

Parts meeting all specified parameters within these categories qualify as direct substitutes. No parameter relaxation or derating is permitted.

Parameter Comparison

Engineering Selection Recommendations

The CSHB0540R-4R7M maintains Active product status with full RoHS3 compliance and REACH unaffected classification, confirming its suitability for current and future production environments. The MSL 1 rating eliminates moisture-related handling constraints during assembly and storage.

When selecting equivalent parts, prioritize components from the CSHB0540R series that maintain identical electrical performance specifications. The shielded construction and magnetic powder core are essential for applications requiring controlled EMI characteristics and stable inductance across the specified current range.

Surface mount compatibility and the nonstandard 5.80 mm × 5.20 mm footprint are critical mechanical constraints. PCB layout and pick-and-place equipment compatibility must be verified against the exact physical dimensions provided.

The 7 A current rating with 7.5 A saturation current establishes the maximum operational envelope. Circuit designs must not exceed these thresholds to maintain component reliability and prevent thermal degradation.

Frequently Asked Questions (FAQ)

Q: What defines a direct substitute for the CSHB0540R-4R7M?

A: A direct substitute must match all electrical parameters (4.7 µH inductance, 7 A current rating, 28.4 mOhm maximum DCR), maintain shielded construction with magnetic powder core, operate across -40°C to 125°C, and fit the nonstandard 5.80 mm × 5.20 mm × 4.00 mm (Max) footprint. RoHS3 compliance and MSL 1 rating are mandatory.

Q: Can inductors with higher current ratings substitute for the CSHB0540R-4R7M?

A: Higher current ratings do not automatically qualify a part as a substitute. The part must maintain the identical 4.7 µH inductance value, 28.4 mOhm maximum DCR, and physical footprint. Electrical performance characteristics must remain within specification.

Q: Is the ±20% inductance tolerance critical for substitution?

A: Yes. The tolerance specification defines the acceptable inductance range (3.76 µH to 5.64 µH). Substitute parts must operate within this tolerance band to ensure circuit performance consistency.

Q: What is the significance of the 7.5 A saturation current specification?

A: The saturation current (Isat) of 7.5 A represents the threshold beyond which the inductor's magnetic core begins to saturate, causing inductance degradation and increased losses. Substitute parts must maintain this specification to prevent circuit malfunction under peak current conditions.

Q: Does the shielded construction affect substitution eligibility?

A: Yes. Shielding is a mandatory requirement. Unshielded inductors cannot substitute for the CSHB0540R-4R7M, as shielding directly impacts EMI performance and crosstalk characteristics in the circuit.

Q: Are there alternative manufacturers for this part?

A: Substitution is limited to parts meeting all specified electrical and mechanical parameters. The provided data identifies CODACA as the manufacturer. Alternative sources must be evaluated against the complete parameter set before qualification.

Q: What role does the nonstandard package play in substitution?

A: The nonstandard 5.80 mm × 5.20 mm footprint is a fixed mechanical constraint. PCB layout, solder pad design, and pick-and-place programming are configured for this specific dimension. Substitute parts must match this footprint exactly.

Q: Can the CSHB0540R-4R7M be used in applications below -40°C or above 125°C?

A: No. The operating temperature range of -40°C to 125°C defines the validated performance envelope. Operation outside this range is not supported and may result in component failure or performance degradation.

Q: What does RoHS3 compliance signify for this component?

A: RoHS3 compliance confirms the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other regulated substances. This certification is mandatory for applications in regulated markets and modern manufacturing environments.

Q: Is the MSL 1 rating advantageous for supply chain management?

A: Yes. MSL 1 (Unlimited) eliminates moisture sensitivity constraints. The component does not require desiccant packaging, controlled humidity storage, or time-limited shelf life management, simplifying logistics and reducing handling costs.
