• Magnetic powder core material
• Physical dimensions: 0.228" L x 0.205" W (5.80mm x 5.20mm)
• Maximum seated height of 0.118" (3.00mm)
• Nonstandard package classification

Environmental & Compliance Parameters:

• Operating temperature range of -40°C to 125°C

Only components meeting all specified parameters within the stated tolerances qualify as direct substitutes for this power choke application.

Parameter Comparison

Engineering Selection Recommendations

The CSHB0530R-R47M maintains Active product status with full ROHS3 compliance and REACH Unaffected designation, ensuring regulatory compliance for current and future applications. The component's MSL 1 rating eliminates moisture sensitivity concerns during storage and handling.

Selection of equivalent parts must prioritize components with identical electrical specifications: 470 nH inductance at ±20% tolerance, 15 A current rating, and 14.5 A saturation current. The DC resistance specification of 5.85 mOhm maximum is critical for power choke applications where thermal performance directly impacts circuit efficiency.

Mechanical compatibility requires surface mount molded construction with shielded configuration and magnetic powder core material. The nonstandard package dimensions (0.228" L x 0.205" W x 0.118" H maximum) must be maintained to ensure PCB layout compatibility and thermal management characteristics.

Environmental specifications including the -40°C to 125°C operating temperature range and 100 kHz test frequency must be preserved in any substitute selection. Compliance certifications (ROHS3, REACH Unaffected) are mandatory for applications subject to regulatory requirements.

Frequently Asked Questions (FAQ)

Q: What defines a direct substitute for the CSHB0530R-R47M?

A: A direct substitute must match all electrical parameters (470 nH inductance, 15 A current rating, 14.5 A Isat, 5.85 mOhm DCR maximum), mechanical specifications (surface mount molded shielded construction, nonstandard package dimensions), and environmental ratings (-40°C to 125°C operation, ROHS3 compliance, MSL 1).

Q: Can inductors with different DC resistance values substitute for this part?

A: No. The 5.85 mOhm maximum DC resistance specification is a critical parameter for power choke applications. Higher resistance values increase power dissipation and reduce circuit efficiency. Substitutes must not exceed this specification.

Q: Is the shielded configuration mandatory for substitution?

A: Yes. The shielded design is specified for this application. Unshielded inductors do not qualify as substitutes due to electromagnetic interference considerations in power choke circuits.

Q: What is the significance of the 14.5 A saturation current specification?

A: The saturation current rating defines the maximum current level before the inductor's magnetic core saturates, causing inductance to degrade. Substitutes must maintain this specification to ensure predictable circuit performance under peak current conditions.

Q: Does the nonstandard package classification affect substitution options?

A: Yes. The nonstandard package dimensions (0.228" L x 0.205" W x 0.118" H maximum) are specific to this component series. Substitutes must maintain identical physical dimensions for PCB layout compatibility and thermal performance.

Q: Are there alternative inductance values that can substitute for 470 nH?

A: No. The 470 nH inductance value is application-specific. Alternative inductance values alter circuit frequency response and filtering characteristics. Only components with 470 nH ±20% tolerance qualify as substitutes.

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

A: The 100 kHz test frequency is the standard measurement condition for this inductor's electrical characteristics. Substitutes must be specified and tested at this frequency to ensure equivalent performance in the target application.

Q: Is ROHS3 compliance required for all substitute parts?

A: Yes. ROHS3 compliance is mandatory for regulatory adherence. All substitute components must maintain this certification status.

Q: Can the operating temperature range be extended in a substitute part?

A: The -40°C to 125°C operating temperature range is the specified limit for this application. Substitutes must support this full range. Extended temperature ratings do not disqualify a component but are not required.

Q: What is the importance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture sensitivity concerns. This simplifies inventory management and eliminates baking requirements before assembly. Substitutes must maintain this MSL rating.
