Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VLS6045EX-2R2N are qualified based on the following criteria:

Primary Matching Parameters:

• Inductance value: 2.2 µH (exact match required)
• Physical dimensions: 6.00mm x 6.00mm footprint (ensures PCB compatibility)
• Mounting type: Surface Mount (SMD)
• Inductance test frequency: 100 kHz

Secondary Compatibility Parameters:

• Current rating: Minimum 4.5 A (acceptable for applications requiring ≤5.1 A continuous current)
• DC resistance: 15–22 mOhm (within acceptable range for power delivery applications)
• Shielding: Shielded or Semi-Shielded (both acceptable for EMI control)
• Core material: Ferrite or Nickel Zinc Ferrite (both suitable for this inductance range)
• Operating temperature: Minimum -40°C to 105°C overlap required
• RoHS3 compliance: Required for regulatory alignment

All substitute parts meet these criteria and are classified as Active products with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

BWVC006060452R2M00 (Pulse Electronics): This substitute provides shielded construction matching the original design intent. The 4.68 A current rating is suitable for applications operating at or below 4.68 A. DC resistance of 18 mOhm is marginally lower than the original, reducing power dissipation. Extended operating temperature range (-55°C to 125°C) provides additional thermal margin. Height of 4.70mm is within acceptable tolerance for most PCB layouts. ROHS3 compliance and MSL 1 rating ensure regulatory and manufacturing compatibility.

SDCH1V6045-2R2M-R (Eaton - Electronics Division): This semi-shielded substitute is suitable for applications where EMI control requirements are less stringent than full shielding. The 4.5 A current rating is the lowest among substitutes and should be selected only for applications with maximum continuous current ≤4.5 A. DC resistance of 22 mOhm (maximum) is higher than the original, resulting in increased power dissipation. Operating temperature range of -40°C to 125°C matches the lower bound of the original. ROHS3 compliance and MSL 1 rating are maintained.

SDCHA1V6045-2R2-R (Eaton - Electronics Division): This semi-shielded substitute offers the highest current rating at 6.0 A, exceeding the original specification and providing design margin for current-limited applications. DC resistance of 15 mOhm is the lowest among all options, minimizing power dissipation. Nickel Zinc Ferrite core material provides alternative magnetic characteristics suitable for higher frequency applications. Extended operating temperature range (-55°C to 125°C) and AEC-Q200 rating indicate automotive-grade qualification. ROHS3 compliance and MSL 1 rating are maintained.

All substitute parts are Active products with confirmed inventory availability and meet regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can I use SDCHA1V6045-2R2-R as a direct replacement for VLS6045EX-2R2N?

A: Yes, for applications requiring ≤6.0 A continuous current. The 6.0 A rating exceeds the original 5.1 A specification, providing design margin. Physical dimensions, inductance value, and mounting type are identical. The semi-shielded construction differs from the original shielded design; verify EMI performance requirements before substitution.

Q: What is the impact of different DC resistance values on circuit performance?

A: DC resistance directly affects power dissipation and voltage drop across the inductor. SDCHA1V6045-2R2-R (15 mOhm) dissipates the least power, while SDCH1V6045-2R2M-R (22 mOhm maximum) dissipates the most. For applications sensitive to thermal performance or efficiency, lower DCR values are preferred. Verify thermal budget and efficiency requirements for your specific application.

Q: Are semi-shielded inductors acceptable replacements for shielded inductors?

A: Semi-shielded inductors provide reduced EMI containment compared to fully shielded designs. Substitution is acceptable only if EMI performance requirements are verified to be compatible with semi-shielded construction. For noise-sensitive applications or those with strict EMI specifications, fully shielded options (BWVC006060452R2M00) are recommended.

Q: What is the significance of the ±20% versus ±30% inductance tolerance?

A: Tighter tolerance (±20%) provides more predictable inductance values across production batches. For applications with strict inductance requirements, ±20% tolerance parts (all substitutes) offer better consistency than the original ±30% specification. For applications with wider tolerance margins, both are acceptable.

Q: Does the Nickel Zinc Ferrite core material in SDCHA1V6045-2R2-R affect frequency response?

A: Nickel Zinc Ferrite exhibits different permeability characteristics compared to standard Ferrite, resulting in altered frequency response. SDCHA1V6045-2R2-R specifies a self-resonant frequency of 55 MHz. Verify frequency response requirements for your application before selecting this substitute.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's regulatory status.
