CSHB0415-4R7M Equivalent & Substitute Parts

Part Overview

The CSHB0415-4R7M 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 value with a 3.8 A current rating and operates across the temperature range of -40°C to 125°C. The part maintains Active product status and is RoHS3 compliant with REACH unaffected classification.

Substitute parts are identified when equivalent electrical and mechanical parameters are required for circuit design continuity, inventory management, or supply chain alternatives. Substitution eligibility is determined by matching critical specifications including inductance value, current rating, DC resistance, shielding characteristics, and physical dimensions.

Engineering Selection Recommendations

The CSHB0415-4R7M maintains Active product status with full RoHS3 compliance and REACH unaffected classification. When selecting equivalent or substitute components, the following engineering criteria apply:

Compliance Verification: All substitute parts must maintain RoHS3 compliance and REACH unaffected status to ensure regulatory alignment with the original component specification.

Product Status: Only components with Active product status are suitable for new design implementations and ongoing production applications.

Electrical Equivalence: Substitute parts must match the inductance value of 4.7 µH within the specified ±20% tolerance band. Current rating and saturation current must both equal 3.8 A. DC resistance must not exceed 92 mOhm maximum.

Physical Compatibility: Substitute components must conform to the nonstandard package dimensions of 0.173" L x 0.165" W (4.40 mm x 4.20 mm) with a maximum seated height of 0.059" (1.50 mm) to ensure PCB layout compatibility and assembly process alignment.

Thermal Performance: Operating temperature range of -40°C to 125°C must be maintained across all substitute selections to ensure functional performance across specified environmental conditions.

Frequently Asked Questions (FAQ)

Q: What defines an equivalent part for the CSHB0415-4R7M?

A: An equivalent part must match all electrical parameters (4.7 µH inductance, 3.8 A current rating, 92 mOhm maximum DC resistance), physical dimensions (0.173" L x 0.165" W, 0.059" maximum height), shielding characteristics (shielded), core material (magnetic powder), and compliance certifications (RoHS3 compliant, REACH unaffected).

Q: Can parts with different inductance values substitute for the CSHB0415-4R7M?

A: No. The inductance value of 4.7 µH is a critical electrical parameter. Substitution requires exact inductance matching within the specified ±20% tolerance band. Different inductance values alter circuit performance and are not acceptable substitutes.

Q: Are unshielded molded inductors acceptable substitutes?

A: No. The CSHB0415-4R7M is specified as shielded. Unshielded variants do not meet the substitution criteria and may introduce electromagnetic interference issues in the circuit application.

Q: What is the significance of the nonstandard package classification?

A: The nonstandard package designation indicates a proprietary or custom form factor specific to the CSHB0415 series. Substitute parts must maintain identical physical dimensions and package configuration to ensure PCB footprint compatibility and assembly process continuity.

Q: Does the Moisture Sensitivity Level (MSL) rating affect substitution eligibility?

A: Yes. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints. Substitute parts must maintain the same MSL classification to ensure equivalent handling, storage, and assembly requirements.

Q: Can the CSHB0415-4R7M be substituted with parts from different manufacturers?

A: Substitution is based strictly on electrical and mechanical parameter matching. Parts from alternative manufacturers are eligible only when all specified parameters, dimensions, and compliance certifications are identical to the original component.

Q: What role does the 100 kHz test frequency play in substitution?

A: The 100 kHz inductance frequency test establishes the measurement standard for the 4.7 µH inductance specification. Substitute parts must be characterized at the same test frequency to ensure electrical equivalence and performance consistency.

Q: Is the ±20% inductance tolerance applied during substitution evaluation?

A: The ±20% tolerance defines the acceptable inductance range for the component itself (3.76 µH to 5.64 µH). Substitute parts must be specified with the same tolerance band and must fall within this range to maintain circuit design margins.
