Substitute Part Grouping Explanation

Substitution eligibility for the CSHB0520R-4R7M is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 4.7 µH
• Inductance tolerance: ±20%
• Current rating: 5 A minimum
• Saturation current (Isat): 5.5 A minimum
• DC resistance: 51.8 mOhm maximum

Mechanical Parameters:

• Mounting type: Surface Mount
• Package dimensions: 0.228" L x 0.205" W (5.80mm x 5.20mm)
• Height seated maximum: 0.079" (2.00mm)
• Shielding: Shielded configuration required

Material & Construction:

• Type: Molded inductor
• Core material: Magnetic Powder

Compliance & Environmental:

• RoHS3 compliance required
• Operating temperature range: -40°C ~ 125°C minimum

Engineering Selection Recommendations

The CSHB0520R-4R7M maintains Active product status with full regulatory compliance across RoHS3 and REACH frameworks. Selection of equivalent parts should prioritize components with identical part numbers from the same manufacturer series, as this ensures consistency in manufacturing processes, material specifications, and performance characteristics.

When sourcing from inventory, confirm that substitute components carry the same Active product status designation. This status indicates ongoing manufacturer support, consistent quality control, and availability of technical documentation. Components with discontinued or obsolete status should not be considered for new design implementations or long-term production requirements.

Compliance certifications—specifically RoHS3 compliance and REACH unaffected status—must be verified on all substitute parts. These certifications are non-negotiable for applications subject to regulatory requirements in target markets. The MSL 1 rating indicates unlimited shelf life under standard storage conditions, eliminating moisture-related handling constraints during procurement and assembly operations.

Frequently Asked Questions (FAQ)

Q: What defines a direct substitute for the CSHB0520R-4R7M?

A: A direct substitute must match all electrical parameters (4.7 µH inductance, 5 A current rating, 51.8 mOhm maximum DCR), mechanical dimensions (5.80mm x 5.20mm x 2.00mm maximum height), shielding configuration, and compliance certifications (RoHS3, REACH unaffected). The component must be a molded inductor with magnetic powder core material in surface mount configuration.

Q: Can inductors with different inductance values substitute for the CSHB0520R-4R7M?

A: No. The inductance value of 4.7 µH is a critical circuit parameter. Substitution with different inductance values alters circuit performance, frequency response, and filtering characteristics. Only components with 4.7 µH inductance and ±20% tolerance are acceptable substitutes.

Q: Are there compatibility concerns with the nonstandard package?

A: The nonstandard package designation indicates this component uses a proprietary footprint specific to the CSHB0520R series. Substitute parts must maintain identical physical dimensions (0.228" L x 0.205" W, 0.079" maximum height) to ensure compatibility with existing circuit board layouts and pick-and-place assembly equipment programming.

Q: What is the significance of the 5.5 A saturation current specification?

A: The saturation current (Isat) of 5.5 A represents the maximum current level before the inductor enters saturation, where inductance degrades significantly. This specification must be met or exceeded in substitute components to maintain performance margin above the 5 A nominal current rating.

Q: Does the shielded configuration affect substitute selection?

A: Yes. The shielded configuration is mandatory for substitute parts. Shielding reduces electromagnetic interference and prevents coupling with adjacent circuit elements. Unshielded inductors are not acceptable substitutes, as they alter EMI performance and circuit behavior.

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

A: The 100 kHz inductance test frequency establishes the measurement standard for the 4.7 µH specification. Substitute components must have inductance values verified at this same frequency to ensure direct electrical equivalence in the target operating frequency range.

Q: Is the ±20% inductance tolerance acceptable for all applications?

A: The ±20% tolerance is the specified manufacturing tolerance for this component series. Applications requiring tighter tolerance control must be evaluated separately. Substitute parts must maintain this same tolerance specification to ensure consistent circuit performance across production batches.

Q: How does the DC resistance specification impact substitute selection?

A: The 51.8 mOhm maximum DCR specification limits resistive losses in the inductor winding. Substitute components with higher DCR values increase power dissipation and heat generation. All substitutes must meet or improve upon this maximum DCR specification.

Q: What is the importance of Active product status for substitutes?

A: Active status indicates the manufacturer actively produces and supports the component with consistent quality control, technical documentation, and supply availability. Substitutes with discontinued or obsolete status may have limited availability, inconsistent specifications, or lack of manufacturer support.

Q: Are there any restrictions on substitute sourcing based on packaging format?

A: Substitute parts must be supplied in Tape & Reel (TR) packaging to maintain compatibility with automated assembly processes. Alternative packaging formats (cut tape, bulk, etc.) require process validation and may introduce handling and traceability complications.
