CSHB0412-2R2M Equivalent & Substitute Parts

Part Overview

The CSHB0412-2R2M is a shielded molded inductor manufactured by CODACA, classified as a power choke for surface mount applications. This component features a 2.2 µH inductance value with a 4.2 A current rating and operates across the temperature range of -40°C to 125°C. The part maintains Active product status and is RoHS3 compliant with REACH unaffected classification.

Substitute parts are identified when equivalent electrical and mechanical parameters are required for circuit design continuity, inventory management, or supply chain alternatives. Substitution eligibility is determined by matching critical specifications including inductance value, current rating, DC resistance, shielding characteristics, and physical dimensions.

• Height seated maximum: 0.047" (1.20 mm)
• Operating temperature range: -40°C ~ 125°C minimum
• Packaging: Tape & Reel (TR)

Parts meeting all specified parameters within stated tolerances are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The CSHB0412-2R2M maintains Active product status with full RoHS3 compliance and REACH unaffected classification. Component selection for this power choke application is based on matching all specified electrical parameters including the 2.2 µH inductance, 4.2 A current rating, and 63 mOhm maximum DC resistance, along with physical dimensions and shielding requirements.

Parts identified as parametric equivalents meet all stated specifications and certifications. Selection between equivalent parts is determined by availability, packaging format (Tape & Reel), and compliance requirements. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity restrictions during storage and handling.

Frequently Asked Questions (FAQ)

Q: What defines a substitute part for the CSHB0412-2R2M?

A: A substitute part must match all critical electrical parameters: 2.2 µH inductance with ±20% tolerance, 4.2 A current rating and saturation current, 63 mOhm maximum DC resistance, and shielded configuration. Physical dimensions (0.173" L x 0.165" W, 0.047" max height), surface mount packaging, and operating temperature range (-40°C ~ 125°C) must also be identical.

Q: Can unshielded inductors substitute for the CSHB0412-2R2M?

A: No. The CSHB0412-2R2M is specified as shielded. Unshielded inductors do not meet the substitution criteria and introduce different electromagnetic characteristics unsuitable for this application.

Q: Are there current rating considerations for substitution?

A: Yes. Substitute parts must support a minimum current rating of 4.2 A with saturation current (Isat) of 4.2 A. Parts with lower current ratings are not acceptable substitutes.

Q: What is the significance of the 63 mOhm maximum DC resistance specification?

A: DC resistance directly affects power dissipation and thermal performance in the circuit. Substitute parts must not exceed 63 mOhm to maintain equivalent electrical behavior and thermal characteristics.

Q: Does the nonstandard package affect substitution eligibility?

A: Yes. The nonstandard package dimensions (0.173" L x 0.165" W, 0.047" max height) are critical for PCB layout and assembly. Substitute parts must match these exact dimensions to ensure mechanical compatibility.

Q: Is the Tape & Reel packaging format a substitution requirement?

A: Yes. The CSHB0412-2R2M is supplied in Tape & Reel (TR) format. Substitute parts must use identical packaging for supply chain and assembly process compatibility.

Q: What compliance certifications are maintained across substitutes?

A: All substitute parts maintain RoHS3 compliance and REACH unaffected status. MSL rating of 1 (Unlimited) applies across all equivalents, indicating no moisture sensitivity restrictions.

Q: Can parts with different inductance tolerance ranges substitute?

A: No. The ±20% tolerance specification is a critical parameter. Substitute parts must maintain this exact tolerance range to ensure circuit performance consistency.

Q: What is the operating temperature significance for substitution?

A: The -40°C ~ 125°C operating range is a specified parameter. Substitute parts must support this full temperature range. Parts with narrower temperature ranges are not acceptable substitutes.
