Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSHB0421R-R47M is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Inductance value of 470 nH with ±20% tolerance
• Current rating of 11.5 A minimum
• Saturation current (Isat) of 13 A minimum
• DC resistance not exceeding 7.8 mOhm

Mechanical Specifications:

• Surface mount molded inductor construction
• Shielded configuration with magnetic powder core
• Physical dimensions of 4.40 mm L x 4.20 mm W x 2.10 mm H (maximum seated height)
• Nonstandard package classification

Environmental & Compliance:

• Operating temperature range of -40°C to 125°C
• RoHS3 compliance requirement
• REACH unaffected status
• Moisture sensitivity level 1 (unlimited)
• Tape & Reel packaging format

Parts meeting all specified parameters within these categories qualify as direct substitutes for the CSHB0421R-R47M in power choke applications.

Engineering Selection Recommendations

The CSHB0421R-R47M maintains Active product status with full regulatory compliance across RoHS3 and REACH designations. Selection of equivalent parts for the CSHB0421R-R47M power choke application is based on the following engineering criteria:

Product Status Alignment: Both the main part and substitute maintain Active status, ensuring continued availability and manufacturing support for production applications.

Compliance Certification: All substitute parts must maintain RoHS3 compliance and REACH unaffected status to satisfy regulatory requirements in target markets. Moisture sensitivity level 1 (unlimited) classification permits standard handling and storage procedures without specialized environmental controls.

Electrical Performance: Substitute parts must deliver the specified 470 nH inductance within ±20% tolerance at 100 kHz test frequency. Current rating of 11.5 A with 13 A saturation current ensures adequate performance margin in power choke circuits. DC resistance specification of 7.8 mOhm maximum controls thermal dissipation and efficiency characteristics.

Mechanical Compatibility: Surface mount configuration with nonstandard package dimensions (4.40 mm x 4.20 mm x 2.10 mm maximum height) requires exact dimensional matching for PCB assembly compatibility. Shielded molded construction with magnetic powder core maintains electromagnetic performance and thermal stability across the -40°C to 125°C operating range.

Supply Chain Considerations: Tape & Reel packaging format ensures compatibility with automated assembly processes. Active product status and documented inventory availability support production scheduling and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the CSHB0421R-R47M?

A: A valid substitute must match all critical electrical parameters (470 nH inductance at ±20% tolerance, 11.5 A current rating, 13 A saturation current, 7.8 mOhm maximum DC resistance), maintain identical mechanical dimensions (4.40 mm x 4.20 mm x 2.10 mm), feature shielded molded construction with magnetic powder core, and maintain RoHS3 compliance with REACH unaffected status.

Q: Can inductors with different inductance values substitute for the CSHB0421R-R47M?

A: No. The 470 nH inductance value is a critical electrical specification. Substitutes must deliver 470 nH within the ±20% tolerance band. Different inductance values alter circuit performance and are not acceptable substitutes.

Q: Are unshielded molded inductors compatible with the CSHB0421R-R47M application?

A: No. The CSHB0421R-R47M is specified as a shielded inductor. Unshielded alternatives do not provide equivalent electromagnetic performance and are not direct substitutes.

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

A: The nonstandard package designation indicates custom mechanical dimensions specific to the CSHB0421R series. Substitute parts must maintain identical physical dimensions (4.40 mm L x 4.20 mm W x 2.10 mm H maximum) to ensure PCB assembly compatibility and mounting reliability.

Q: Does the CSHB0421R-R47M require special handling due to moisture sensitivity?

A: No. The moisture sensitivity level 1 (unlimited) classification indicates no special moisture control requirements during storage, handling, or assembly. Standard industrial storage conditions are acceptable.

Q: Can the CSHB0421R-R47M operate outside the -40°C to 125°C temperature range?

A: No. The operating temperature range of -40°C to 125°C defines the limits for reliable electrical and mechanical performance. Operation outside this range is not specified and may result in performance degradation or component failure.

Q: What is the significance of the 100 kHz inductance test frequency?

A: The 100 kHz test frequency is the standard measurement condition at which the 470 nH inductance value is verified. This frequency is typical for power choke applications and defines the reference point for inductance tolerance specifications.

Q: Are there current rating considerations for substitute selection?

A: Yes. The 11.5 A current rating and 13 A saturation current are critical specifications. Substitute parts must meet or exceed these ratings. Lower-rated inductors will saturate prematurely and fail to deliver required performance.

Q: What compliance certifications are required for substitute parts?

A: Substitute parts must maintain RoHS3 compliance and REACH unaffected status. These certifications ensure regulatory compliance in target markets and support environmental and safety requirements.

Q: Is the Tape & Reel packaging format interchangeable with other packaging options?

A: No. The Tape & Reel (TR) packaging format is specified for automated assembly compatibility. Substitute parts must be supplied in identical Tape & Reel packaging to ensure assembly line compatibility and handling procedures.
