Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSHB0421-100M is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 10 µH
• Inductance tolerance: ±20%
• Current rating: 2.5 A minimum
• Saturation current: 2.5 A minimum
• DC resistance: 129 mOhm maximum

Physical & Mechanical Parameters:

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

Environmental & Compliance Parameters:

• Operating temperature range: -40°C to 125°C minimum
• RoHS3 compliance required
• Moisture sensitivity level: MSL 1 or better
• Packaging: Tape & Reel format

Substitute parts must satisfy all parameters within the specified tolerances and limits. No parameter relaxation or derating is permitted for substitution classification.

Engineering Selection Recommendations

The CSHB0421-100M maintains Active product status with full RoHS3 compliance and REACH unaffected classification, confirming its suitability for current production environments. The part is available in standard Tape & Reel packaging with unlimited moisture sensitivity rating, eliminating special handling requirements for storage and assembly operations.

Selection of equivalent parts should prioritize components with identical electrical specifications, particularly the 10 µH inductance value, ±20% tolerance, and 2.5 A current rating. The magnetic powder core construction and shielded design are essential for EMI suppression in power conversion applications and must not be substituted with unshielded or alternative core material variants.

Physical compatibility is critical for surface mount assembly. The nonstandard package dimensions (4.40 mm x 4.20 mm footprint with 2.10 mm maximum height) must be matched exactly to ensure proper placement on automated assembly equipment and compliance with PCB layout constraints.

Compliance certifications including RoHS3 and REACH status must be verified for all substitute selections to maintain regulatory conformance across target markets.

Frequently Asked Questions (FAQ)

Q: Can the CSHB0421-100M be substituted with inductors from other manufacturers?

A: Substitution is limited to parts meeting all specified electrical and mechanical parameters. Alternative manufacturers may produce equivalent 10 µH shielded molded inductors with 2.5 A current rating and identical physical dimensions. However, only parts explicitly listed as parametric equivalents satisfy substitution criteria.

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

A: The ±20% tolerance defines the acceptable inductance range from 8 µH to 12 µH at the 100 kHz test frequency. Substitute parts must maintain this identical tolerance specification to ensure circuit performance consistency. Parts with tighter or looser tolerances are not interchangeable.

Q: Are there any restrictions on the core material for substitution?

A: The magnetic powder core material is specified for this application. Substitute parts must use identical core construction. Ferrite core or other alternative materials are not acceptable substitutes, as they produce different frequency response and saturation characteristics.

Q: Why is shielding a mandatory requirement?

A: Shielding is essential for EMI containment in power conversion circuits. Unshielded inductors generate magnetic field radiation that can interfere with adjacent components. Substitute parts must maintain the shielded design specification.

Q: Can the CSHB0421-100M be used in applications exceeding 2.5 A?

A: No. The 2.5 A current rating and saturation current specification define the maximum safe operating point. Operation beyond this limit results in core saturation, inductance collapse, and potential component failure. Substitute parts must maintain identical current ratings.

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

A: The nonstandard package designation indicates custom footprint dimensions (4.40 mm x 4.20 mm). This specific size is optimized for particular PCB layouts. Substitute parts must match these exact dimensions to ensure mechanical compatibility with existing designs.

Q: Is the MSL 1 rating significant for procurement?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. Standard storage and handling procedures apply without special desiccant packaging or shelf-life limitations. This simplifies inventory management and reduces procurement complexity.

Q: Can the operating temperature range be extended for substitute parts?

A: No. The -40°C to 125°C operating range is a fixed specification. Substitute parts must support this identical temperature range. Parts with narrower temperature specifications are not acceptable for applications requiring full range operation.

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

A: The 100 kHz test frequency is the standard measurement point for inductance verification. Substitute parts must have inductance specifications measured at this identical frequency to ensure direct comparison and circuit compatibility.

Q: Are RoHS3 and REACH compliance mandatory for substitutes?

A: Yes. RoHS3 compliance and REACH unaffected status are regulatory requirements for most markets. Substitute parts must maintain identical compliance certifications to ensure legal and contractual conformance.
