Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSBX2212-470M is determined by strict electrical and mechanical parameter matching within the CSBX2212 series. The critical parameters that define substitutability are:

Electrical Parameters:

• Inductance value of 47 µH with ±20% tolerance
• Current rating of 9 A minimum
• Saturation current (Isat) of 18.5 A minimum
• DC resistance not exceeding 21.4 mOhm

Mechanical Parameters:

• Shielded wirewound construction with metal composite core
• Surface mount nonstandard package
• Physical dimensions: 0.886" L x 0.866" W (22.50mm x 22.00mm)
• Maximum seated height of 0.488" (12.40mm)

Environmental & Compliance Parameters:

• Operating temperature range of -55°C ~ 150°C
• AEC-Q200 automotive rating
• RoHS3 compliance
• MSL rating of 1 (Unlimited)

Parts meeting all these parameters are considered direct parametric equivalents and may be substituted without circuit redesign or thermal management modifications.

Parameter Comparison

Engineering Selection Recommendations

The CSBX2212-470M is an Active product with established supply availability (1218 pieces in stock). When selecting equivalent parts, prioritize components that maintain identical electrical specifications, particularly the 47 µH inductance value, 9 A current rating, and 18.5 A saturation current. The AEC-Q200 automotive qualification and RoHS3 compliance are critical for applications requiring automotive-grade reliability and environmental regulatory adherence.

Surface mount nonstandard package compatibility is essential for PCB layout and assembly process alignment. The metal composite core construction and shielded design provide electromagnetic interference mitigation and thermal stability across the -55°C to 150°C operating range. DC resistance specification of 21.4 mOhm maximum directly impacts power dissipation calculations and thermal management in the application circuit.

Parts meeting all specified parameters are suitable for direct substitution without circuit redesign, provided that the application's thermal, electrical, and mechanical constraints remain within the component's rated specifications.

Frequently Asked Questions (FAQ)

Q: What makes a part a true equivalent to the CSBX2212-470M?

A: A true equivalent must match all critical electrical parameters (47 µH inductance, 9 A current rating, 18.5 A saturation current, 21.4 mOhm maximum DCR), core material (metal composite), shielding type (shielded), construction method (wirewound), physical dimensions (22.50mm x 22.00mm x 12.40mm maximum height), and compliance ratings (AEC-Q200, RoHS3). The part must also operate across the -55°C to 150°C temperature range.

Q: Can I substitute a part with different inductance tolerance?

A: No. The CSBX2212-470M specifies ±20% tolerance. Substitutes must maintain this tolerance specification to ensure circuit performance and stability across production variations.

Q: Is the nonstandard package size critical for substitution?

A: Yes. The nonstandard 22.50mm x 22.00mm footprint with 12.40mm maximum seated height is specific to this component family. PCB layout and assembly equipment are configured for this exact package geometry. Substitutes must match these dimensions precisely.

Q: What is the significance of the AEC-Q200 rating?

A: AEC-Q200 is an automotive-grade qualification standard. This rating indicates the component meets stringent reliability, temperature cycling, and performance requirements for automotive applications. Substitutes must maintain this certification for applications requiring automotive compliance.

Q: Does RoHS3 compliance affect substitution eligibility?

A: Yes. RoHS3 compliance is a regulatory requirement for many markets and applications. Substitute parts must maintain RoHS3 compliance status to ensure legal and contractual compliance in the supply chain.

Q: Why is DC resistance specification important for substitution?

A: DC resistance directly affects power dissipation and thermal performance. The 21.4 mOhm maximum specification ensures predictable heat generation in the application circuit. Substitutes exceeding this specification will generate excess heat and may cause thermal management issues.

Q: Can I use a part with higher saturation current as a substitute?

A: A substitute with saturation current equal to or greater than 18.5 A is acceptable from an electrical standpoint. However, all other parameters must remain identical. Higher saturation current does not provide additional benefit if other specifications differ.

Q: What is the MSL rating and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control requirements. This simplifies storage, handling, and logistics. Substitutes must maintain MSL 1 rating to avoid additional moisture management procedures during assembly.
