Parameter Comparison

Engineering Selection Recommendations

The CSHB0430R-1R0M maintains Active product status with full RoHS3 compliance and MSL 1 rating, indicating unrestricted moisture handling and long-term availability. Selection of equivalent parts should prioritize components with identical Active status to ensure supply chain continuity and manufacturing support.

All substitute parts must maintain ROHS3 compliance and MSL 1 classification to satisfy environmental and reliability requirements. Components with downgraded compliance status or obsolete product designations are not suitable for direct substitution.

The shielded magnetic powder core construction is essential for EMI containment in power choke applications. Substitutes must retain this core material and shielding configuration to preserve electromagnetic performance characteristics.

Current rating and saturation current specifications establish the maximum operating envelope. Substitute parts must meet or exceed the 11.5 A current rating and 9.6 A saturation current to prevent thermal stress and component failure under specified load conditions.

Frequently Asked Questions (FAQ)

Q: Can the CSHB0430R-1R0M be substituted with a different inductance value?

A: No. The 1 µH inductance value is a critical electrical parameter. Substitution is limited to parts with identical 1 µH inductance specifications. Different inductance values will alter circuit performance and are not acceptable substitutes.

Q: What is the significance of the ±20% inductance tolerance?

A: The ±20% tolerance defines the acceptable range of inductance variation from the nominal 1 µH value (0.8 µH to 1.2 µH). Substitute parts must maintain this same tolerance specification to ensure circuit compatibility and performance predictability.

Q: Are lower DC resistance values acceptable in substitute parts?

A: Yes. The 12.1 mOhm maximum specification establishes an upper limit. Substitute parts with lower DC resistance values are acceptable and provide improved efficiency. However, DC resistance values exceeding 12.1 mOhm are not suitable substitutes.

Q: Can this component be used in applications requiring higher current ratings?

A: No. The 11.5 A current rating is the maximum continuous current specification. Applications requiring higher current capacity require components from different product families with higher current ratings.

Q: Is the shielded configuration mandatory for substitution?

A: Yes. The shielded design is essential for EMI containment in power choke applications. Unshielded inductors are not acceptable substitutes and will not provide equivalent electromagnetic performance.

Q: What does MSL 1 rating mean for component handling?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited floor life. The component does not require special moisture control during storage or handling, simplifying logistics and reducing component damage risk compared to higher MSL ratings.

Q: Are the package dimensions critical for PCB layout compatibility?

A: Yes. The 4.40 mm × 4.20 mm × 3.00 mm (maximum height) dimensions are fixed for this product family. Substitute parts must maintain identical package dimensions to ensure PCB footprint compatibility and assembly process alignment.

Q: Can substitute parts have different operating temperature ranges?

A: No. The -40°C to 125°C operating temperature range is a specified parameter. Substitute parts must support this identical temperature range to ensure reliable operation across all application environments.

Q: What compliance certifications are required for substitute parts?

A: Substitute parts must maintain ROHS3 compliance and REACH unaffected status. These certifications are mandatory for regulatory compliance and environmental responsibility in manufacturing and end-of-life disposal.
