Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSHB0430R-3R3M is determined by strict equivalence across the following critical parameters:

Electrical Characteristics:

• Inductance value of 3.3 µH with ±20% tolerance
• Current rating of 7.5 A minimum
• Saturation current (Isat) of 6.5 A or greater
• DC resistance (DCR) not exceeding 30.5 mOhm

Mechanical & Physical Requirements:

• Surface mount molded inductor construction
• Shielded core configuration
• Magnetic powder core material
• Nonstandard package dimensions: 0.173" L x 0.165" W (4.40 mm x 4.20 mm)
• Maximum seated height of 0.118" (3.00 mm)

Environmental & Compliance Requirements:

• Operating temperature range of -40°C to 125°C
• ROHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected status
• Tape & Reel packaging format

Parts meeting all specified parameters within these categories are classified as parametric equivalents and direct substitutes.

Engineering Selection Recommendations

The CSHB0430R-3R3M is an active product with confirmed availability of 1926 pieces in new original stock condition. Selection of equivalent parts should prioritize components with identical part numbers from the same manufacturer series, as this ensures full functional and mechanical compatibility.

All substitute candidates must maintain active product status to ensure long-term supply chain viability and continued manufacturer support. Compliance certifications including ROHS3 and REACH Unaffected status are mandatory for applications subject to environmental regulations.

The nonstandard package dimensions and specific saturation current rating of 6.5 A are critical constraints that limit substitution options. Any alternative component must match these specifications exactly to ensure proper circuit performance and thermal management within the specified operating temperature range of -40°C to 125°C.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the CSHB0430R-3R3M?

A: A valid substitute must match all electrical parameters (3.3 µH inductance, 7.5 A current rating, 6.5 A saturation current, 30.5 mOhm maximum DCR), mechanical dimensions (0.173" L x 0.165" W, 0.118" maximum height), core material (magnetic powder), shielding configuration, and compliance certifications (ROHS3, REACH Unaffected).

Q: Can I use a different inductance value as a substitute?

A: No. The inductance value of 3.3 µH is a critical electrical parameter. Substitutes must maintain this exact value within the specified ±20% tolerance. Different inductance values will alter circuit performance and are not acceptable substitutes.

Q: Are there current rating variations that are acceptable?

A: No. The 7.5 A current rating and 6.5 A saturation current are fixed requirements. Substitute parts must meet or exceed these specifications. Lower current ratings are not acceptable for this application.

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

A: The nonstandard package designation indicates that this component uses custom dimensions (0.173" L x 0.165" W, 0.118" maximum height) that do not conform to industry standard footprints. Substitutes must match these exact dimensions to ensure PCB compatibility and proper mounting.

Q: Does the shielded configuration affect substitution options?

A: Yes. The shielded configuration is a mandatory requirement. Unshielded inductors are not acceptable substitutes, as shielding affects electromagnetic interference characteristics and circuit performance.

Q: Is the Tape & Reel packaging format interchangeable with other packaging types?

A: The specified packaging format is Tape & Reel (TR). While this is a standard reel format, substitutes must be supplied in this same packaging configuration to ensure compatibility with automated assembly processes.

Q: What is the importance of the Moisture Sensitivity Level (MSL) rating?

A: The MSL 1 (Unlimited) rating indicates that this component has no moisture sensitivity restrictions and does not require special handling or storage conditions. Substitute parts must maintain this same MSL classification to avoid introducing additional supply chain or assembly constraints.

Q: Can I substitute with a part from a different manufacturer?

A: Substitution with parts from different manufacturers is possible only if the alternative component meets all specified electrical, mechanical, and compliance parameters. However, the provided data indicates that the CSHB0430R-3R3M from CODACA is the primary reference part, and direct equivalents from the same manufacturer series are preferred.
