Substitute Part Grouping Explanation

Substitution of the CSHB0421R-150M is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters establish the substitution criteria:

Electrical Parameters:

• Inductance value: 15 µH with ±20% tolerance
• Current rating: 2.2 A minimum
• Saturation current (Isat): 2.2 A
• DC resistance: 255 mOhm maximum
• Inductance test frequency: 100 kHz

Mechanical Parameters:

• Mounting type: Surface Mount
• Package dimensions: 0.173" L x 0.165" W (4.40 mm x 4.20 mm)
• Maximum seated height: 0.083" (2.10 mm)
• Core material: Magnetic Powder
• Shielding: Shielded configuration

Environmental & Compliance Parameters:

• Operating temperature range: -40°C to 125°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)
• REACH unaffected status

Substitute parts must match all specified parameters without deviation. No parameter relaxation or tolerance expansion is permitted for substitution classification.

Parameter Comparison

Engineering Selection Recommendations

The CSHB0421R-150M maintains Active product status with full availability of 1631 pieces in stock. This component is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage and handling.

For applications requiring this 15 µH shielded molded inductor with 2.2 A current rating and 255 mOhm maximum DC resistance, the CSHB0421R-150M from CODACA is the specified component. The part's nonstandard package configuration with precise dimensional specifications (4.40 mm x 4.20 mm x 2.10 mm maximum height) requires exact mechanical compatibility verification in surface mount assembly processes.

Selection of equivalent parts must maintain identical electrical performance across the 100 kHz test frequency and operating temperature range of -40°C to 125°C. The shielded magnetic powder core construction is integral to the component's functional specification and cannot be substituted with alternative core materials or unshielded configurations.

Frequently Asked Questions (FAQ)

Q: What defines an equivalent substitute for the CSHB0421R-150M?

A: An equivalent substitute must match all electrical parameters (15 µH inductance at ±20% tolerance, 2.2 A current rating, 2.2 A saturation current, 255 mOhm maximum DCR), mechanical specifications (surface mount, nonstandard package, 4.40 mm x 4.20 mm x 2.10 mm maximum height), core material (magnetic powder, shielded), and environmental ratings (-40°C to 125°C operating range). No parameter deviation is permitted for substitution classification.

Q: Can the CSHB0421R-150M be replaced with a different inductance value?

A: No. The 15 µH inductance value is a critical electrical specification. Substitution with alternative inductance values does not qualify as an equivalent part and requires complete circuit redesign validation.

Q: Is the shielded configuration mandatory for substitution?

A: Yes. The shielded design is specified in the component description and is integral to the electrical performance. Unshielded inductors do not qualify as substitutes.

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

A: The nonstandard package designation indicates this component uses a proprietary form factor specific to CODACA's CSHB0421R series. The precise dimensions (4.40 mm x 4.20 mm x 2.10 mm maximum height) must be verified for PCB footprint compatibility and assembly clearance during component selection.

Q: Are there any temperature derating considerations for the CSHB0421R-150M?

A: The component is rated for operation across -40°C to 125°C. Performance characteristics at temperature extremes within this range are determined by the magnetic powder core material and should be evaluated against specific application requirements.

Q: Does the MSL rating of 1 affect component handling?

A: MSL 1 (Unlimited) indicates no moisture sensitivity constraints. The component does not require special dry storage, desiccant packaging, or bake-out procedures prior to assembly.

Q: What is the significance of ROHS3 compliance for this inductor?

A: ROHS3 compliance confirms the component meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, hexavalent chromium, and specified brominated flame retardants. This certification is required for many regulated markets and applications.

Q: Can the CSHB0421R-150M be used in applications requiring higher current ratings?

A: No. The 2.2 A current rating and 2.2 A saturation current are fixed specifications. Operation above these ratings results in core saturation and loss of inductance. Applications requiring higher current capacity require selection of alternative components with higher current ratings.
