Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CSHB0421-2R2M are identified through strict parametric matching across the following critical specifications:

Electrical Parameters:

• Inductance value of 2.2 µH with ±20% tolerance
• Current rating of 5.5 A minimum
• Saturation current (Isat) of 5.5 A
• DC resistance not exceeding 29.5 mOhm

Mechanical Parameters:

• Surface mount molded inductor construction
• Shielded core design
• Magnetic powder core material
• Physical dimensions: 4.40 mm L x 4.20 mm W x 2.10 mm H (Max)
• Nonstandard package classification

Environmental & Compliance Parameters:

• Operating temperature range of -40°C to 125°C
• ROHS3 compliance
• MSL 1 rating
• REACH unaffected status
• Tape & Reel packaging format

Substitute parts must satisfy all listed parameters without deviation to ensure functional equivalence and direct circuit board compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CSHB0421-2R2M maintains Active product status with confirmed inventory availability of 1829 pieces in new original condition. This part is ROHS3 compliant and carries REACH unaffected status, meeting current regulatory requirements for electronic component procurement in regulated markets.

When selecting equivalent or substitute parts, prioritize components with identical electrical specifications: 2.2 µH inductance at ±20% tolerance, 5.5 A current rating, and 29.5 mOhm maximum DC resistance. Mechanical compatibility requires matching the nonstandard surface mount package dimensions of 4.40 mm x 4.20 mm x 2.10 mm (Max height) to ensure proper circuit board assembly without design modifications.

Environmental performance across the -40°C to 125°C operating temperature range must be maintained. MSL 1 rating confirms unlimited moisture sensitivity protection, suitable for standard storage and handling conditions without special precautions.

Compliance certifications including ROHS3 and REACH unaffected status should be verified for all substitute candidates to maintain regulatory alignment with procurement standards and end-use application requirements.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the CSHB0421-2R2M?

A: A valid substitute must match all specified electrical parameters (2.2 µH inductance, 5.5 A current rating, 29.5 mOhm maximum DCR), core material (magnetic powder), shielding type (shielded), and physical dimensions (4.40 mm x 4.20 mm x 2.10 mm Max). The substitute must also maintain the same operating temperature range (-40°C to 125°C), RoHS3 compliance, and MSL 1 rating.

Q: Can parts with different inductance tolerances be substituted?

A: No. The CSHB0421-2R2M specifies ±20% inductance tolerance. Substitute parts must maintain this identical tolerance specification to ensure circuit performance consistency.

Q: Are there packaging format restrictions for substitutes?

A: Yes. The CSHB0421-2R2M is supplied in Tape & Reel (TR) format. Substitute parts must be available in the same packaging format to maintain compatibility with automated assembly processes.

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

A: The nonstandard package designation indicates this component uses a proprietary or non-IPC standardized footprint. Substitute parts must have identical physical dimensions and mounting characteristics to ensure direct board-level compatibility without layout modifications.

Q: Does the shielded design affect substitution criteria?

A: Yes. The shielded construction is a critical parameter. Substitute parts must incorporate shielded core design to maintain electromagnetic interference (EMI) performance and circuit isolation characteristics of the original design.

Q: What is the importance of MSL 1 rating for this component?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Substitute parts must maintain this MSL 1 rating to avoid introducing moisture sensitivity management requirements into procurement and assembly processes.

Q: How does the 100 kHz test frequency relate to inductance specifications?

A: The 100 kHz inductance test frequency is the standard measurement condition at which the 2.2 µH value is verified. Substitute parts must be characterized at the same test frequency to ensure inductance value equivalence under identical measurement conditions.

Q: Are there current derating considerations for the 5.5 A rating?

A: The 5.5 A current rating represents both the continuous current rating and saturation current (Isat). Substitute parts must maintain this identical specification. Circuit design should account for the 29.5 mOhm maximum DC resistance when calculating power dissipation at rated current.
