CDC5D23BNP-2R2MC Equivalent & Substitute Parts

Part Overview

The CDC5D23BNP-2R2MC is a 2.2 µH fixed unshielded inductor manufactured by Sumida America Components Inc., designed for surface mount applications with a current rating of 2.16 A and maximum DC resistance of 39mOhm. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent inductance values, compatible current ratings, and matching package classifications are available from alternative manufacturers. Substitution becomes necessary when the primary part reaches end-of-life status, supply constraints occur, or design requirements permit tolerance variations within acceptable electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDC5D23BNP-2R2MC are qualified based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Inductance value: 2.2 µH (exact match required)
• Current rating: minimum 2.16 A
• DC resistance: within acceptable operating limits
• Core material: Ferrite
• Mounting type: Surface Mount
• Package classification: Nonstandard
• Compliance: RoHS3 and MSL 1 rating

Tolerance Considerations: Inductance tolerance variations (±10%, ±20%, ±30%) are acceptable provided the application circuit design accommodates the specified tolerance band. Substitute parts with wider tolerances remain functionally equivalent when the circuit topology permits inductance variation within the stated range.

Shielding Variation: While the main part is unshielded, the substitute SRU5028-2R2Y is shielded. Shielded inductors provide electromagnetic interference (EMI) containment and are compatible in applications where the main part is unshielded, as shielding represents an enhancement rather than a functional limitation.

Engineering Selection Recommendations

B82462A4222M000 (EPCOS - TDK Electronics):

This substitute maintains electrical equivalence with the CDC5D23BNP-2R2MC through matching 2.2 µH inductance and ferrite core construction. The current rating of 2.3 A exceeds the main part requirement of 2.16 A. DC resistance of 42 mOhm is within acceptable operating margins. The extended operating temperature range (-55°C to 150°C) provides thermal headroom beyond the main part specification. AEC-Q200 automotive qualification rating indicates reliability certification for demanding applications. ROHS3 compliance and MSL 1 rating match the main part. Selection of this substitute is appropriate for applications requiring extended temperature performance or automotive-grade reliability assurance.

SRU5028-2R2Y (Bourns Inc.):

This substitute provides 2.2 µH inductance with superior current handling at 3.2 A, exceeding the main part by 1.14 A. DC resistance of 21 mOhm is significantly lower than the main part, resulting in reduced power dissipation. Shielded construction provides EMI containment not present in the unshielded main part. Operating temperature range of -40°C to 125°C covers the main part specification with extended upper limit. ROHS3 compliance and MSL 1 rating are maintained. Selection of this substitute is appropriate for applications where lower DC resistance, higher current capacity, or EMI shielding provides circuit performance benefits.

Both substitutes maintain Active product status, ensuring continued availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the B82462A4222M000 directly replace the CDC5D23BNP-2R2MC?

A: Yes. Both parts share 2.2 µH inductance, ferrite core material, surface mount configuration, and nonstandard package classification. The B82462A4222M000 provides higher current rating (2.3 A vs. 2.16 A) and extended temperature range (-55°C to 150°C vs. -40°C to 100°C). DC resistance of 42 mOhm is within acceptable operating limits. Inductance tolerance of ±20% is wider than the main part's ±10%, requiring circuit design verification if tight inductance tolerance is critical.

Q: What is the advantage of the SRU5028-2R2Y over the main part?

A: The SRU5028-2R2Y offers three primary advantages: (1) Lower DC resistance of 21 mOhm reduces power dissipation by approximately 46% compared to the 39 mOhm main part; (2) Higher current rating of 3.2 A provides 48% additional current capacity; (3) Shielded construction contains electromagnetic fields, reducing EMI coupling to adjacent circuit elements. These characteristics make the SRU5028-2R2Y suitable for high-current or noise-sensitive applications.

Q: Does shielding in the SRU5028-2R2Y affect compatibility with the unshielded main part?

A: No. Shielding is a functional enhancement that does not prevent substitution. An unshielded inductor can be replaced with a shielded inductor without circuit modification. The shielded design provides additional EMI containment while maintaining electrical equivalence at the specified inductance value.

Q: Are all three parts qualified for the same temperature range?

A: No. The CDC5D23BNP-2R2MC operates from -40°C to 100°C. The B82462A4222M000 extends to -55°C to 150°C, providing wider thermal coverage. The SRU5028-2R2Y operates from -40°C to 125°C. Application thermal requirements determine which substitute is appropriate.

Q: What is the significance of inductance tolerance differences?

A: Inductance tolerance defines the acceptable variation from the nominal 2.2 µH value. The main part specifies ±10% (2.0 to 2.4 µH). The B82462A4222M000 specifies ±20% (1.76 to 2.64 µH), and the SRU5028-2R2Y specifies ±30% (1.54 to 2.86 µH). Applications with tight frequency or impedance requirements may require the tighter tolerance of the main part. Applications with broader tolerance margins can accommodate wider tolerance substitutes.

Q: Are all parts RoHS3 compliant?

A: Yes. The CDC5D23BNP-2R2MC, B82462A4222M000, and SRU5028-2R2Y are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with lead-free soldering processes and long-term storage without desiccant requirements.

Q: What does AEC-Q200 qualification on the B82462A4222M000 indicate?

A: AEC-Q200 is an automotive electronics qualification standard. This certification indicates the B82462A4222M000 has undergone rigorous reliability testing for automotive applications, including thermal cycling, vibration, and environmental stress screening. This qualification is relevant for automotive or mission-critical applications requiring documented reliability assurance.
