Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDEP106NP-2R2MC-88 is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 2.2 µH (±20% tolerance)
• Inductance test frequency: 100 kHz
• Core material: Ferrite
• Mounting type: Surface Mount
• RoHS3 compliance

Secondary Compatibility Factors:

• Current rating must equal or exceed 13.5 A
• DC resistance must not exceed 3.44 mOhm
• Operating temperature range must encompass -40°C to 105°C minimum
• Saturation current must support application requirements

Shielding Consideration: The main part is shielded. Substitute parts may be shielded or unshielded depending on electromagnetic interference requirements of the application circuit.

Parameter Comparison

Engineering Selection Recommendations

7443330220 (Würth Elektronik WE-HCC Series)

This part qualifies as a direct substitute based on matching inductance value, tolerance, core material, and shielding configuration. The 16.5 A current rating exceeds the 13.5 A requirement of the main part. The extended operating temperature range (-40°C to 125°C) provides additional thermal margin. DC resistance at 4.8 mOhm is within acceptable tolerance for most applications, though 1.36 mOhm higher than the original specification. The part is active and in production, ensuring long-term availability. Shielded construction maintains electromagnetic compatibility characteristics of the original design.

HCF1305-2R2-R (Eaton HCF1305 Series)

This part meets inductance, tolerance, and core material requirements with superior current rating (16.3 A) and lower DC resistance (3.1 mOhm). Extended operating temperature range (-40°C to 125°C) exceeds original specifications. However, this part is unshielded, which may introduce electromagnetic interference considerations in sensitive applications. Smaller footprint (5.00 mm height) offers space advantages. The part is active and in production with established supply chain. Selection requires confirmation that unshielded operation is acceptable for the target application.

Both substitute parts comply with ROHS3 standards and maintain unlimited moisture sensitivity rating consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can the 7443330220 directly replace the CDEP106NP-2R2MC-88 without circuit modification?

A: Yes. Both parts share identical inductance value (2.2 µH), tolerance (±20%), core material (ferrite), and shielding configuration. The higher current rating and saturation current of the substitute provide additional design margin. DC resistance difference of 1.36 mOhm is negligible in most power conversion applications. Verify that the slightly larger footprint (10.90mm L x 10.00mm W vs. 10.00mm x 10.00mm) accommodates your PCB layout.

Q: Why is the HCF1305-2R2-R unshielded while the original part is shielded?

A: Shielding is a design choice that affects electromagnetic field containment and susceptibility to external interference. The unshielded HCF1305-2R2-R reduces component height (5.00 mm vs. 6.50 mm) and cost. Selection between shielded and unshielded depends on circuit layout, proximity to sensitive signals, and EMI requirements. Evaluate unshielded operation through circuit simulation or prototype testing if electromagnetic compatibility is critical.

Q: What is the impact of the 4.8 mOhm DC resistance in the Würth part versus the 3.44 mOhm original specification?

A: At 13.5 A continuous current, the additional 1.36 mOhm resistance increases power dissipation by approximately 0.25 mW. This is typically insignificant in most applications. Calculate actual thermal impact using the formula: P = I² × R. If the inductor operates at saturation current (9.6 A for original, 22 A for substitute), verify that thermal performance remains acceptable.

Q: Are both substitute parts available in the same packaging format as the original?

A: The Würth part (7443330220) is supplied in Cut Tape and Digi-Reel formats. The Eaton part (HCF1305-2R2-R) is supplied in Tape & Reel format. Both are surface mount compatible. Confirm packaging compatibility with your assembly process and procurement requirements.

Q: What is the significance of the higher saturation current in the Würth substitute (22 A vs. 9.6 A)?

A: Higher saturation current indicates greater inductance stability under transient current spikes. The Würth part maintains inductance value more reliably during overcurrent conditions. This provides additional design margin for applications with variable or pulsed current profiles.

Q: Do both substitute parts meet the same compliance standards as the original?

A: Yes. All three parts are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Both substitutes carry ECCN EAR99 and HTSUS 8504.50.4000 classifications identical to the original. The Würth part includes REACH Unaffected status; the Eaton part includes REACH Unaffected status. Compliance documentation is equivalent across all three parts.
