Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0412CDMCDS-4R7MC are selected based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Electrical Parameters (Critical):

• Inductance value: 4.7 µH (exact match required)
• Inductance tolerance: ±20% (matching specification)
• Shielding: Shielded configuration
• Mounting type: Surface Mount

Mechanical Parameters (Critical):

• Package classification: Nonstandard (same form factor category)
• Physical dimensions: Compatible with 0412 footprint envelope

Performance Parameters (Qualifying):

• Current rating: Minimum 1.4 A continuous
• DC resistance: Within acceptable operating limits
• Saturation current: Minimum 2.7 A
• Operating temperature range: Must encompass -40°C to 105°C

Compliance Parameters:

• RoHS3 compliance required
• Moisture sensitivity level: MSL 1 (Unlimited)

The identified substitute parts meet these criteria while accommodating minor variations in core material composition and DC resistance specifications within acceptable engineering tolerances.

Engineering Selection Recommendations

SPD62R-472M (API Delevan Inc.) - Primary Substitute

The SPD62R-472M is the recommended primary substitute for the 0412CDMCDS-4R7MC. This part maintains identical inductance (4.7 µH) and tolerance (±20%) specifications. The current rating of 2 A exceeds the original 1.4 A requirement, providing operational margin. DC resistance of 150mOhm Max is lower than the original 180mOhm, resulting in reduced power dissipation. The extended operating temperature range (-55°C to 125°C) encompasses the original specification. Active product status ensures long-term availability and supply chain continuity. RoHS3 compliance and MSL 1 rating match the original part. Physical dimensions (6.60mm x 6.20mm x 3.00mm) represent a larger footprint than the original, requiring PCB layout verification.

SPM4015T-4R7M (TDK Corporation) - Secondary Substitute

The SPM4015T-4R7M provides an alternative substitute with matching inductance and tolerance specifications. Current rating of 1.8 A exceeds the original 1.4 A requirement. DC resistance of 206.5mOhm Max is higher than the original 180mOhm specification, resulting in increased power dissipation. Saturation current of 2.7 A matches the original part exactly. Physical dimensions (4.40mm x 4.10mm x 1.50mm) are closely aligned with the original footprint, minimizing PCB layout modifications. Operating temperature range (-40°C to 125°C) encompasses the original specification. Obsolete product status limits future availability. RoHS3 compliance and MSL 1 rating match the original part.

Frequently Asked Questions (FAQ)

Q: Can the SPD62R-472M be used as a direct replacement for the 0412CDMCDS-4R7MC?

A: The SPD62R-472M is electrically compatible with identical inductance and tolerance specifications. However, the larger physical dimensions (6.60mm x 6.20mm versus 4.50mm x 4.10mm) require PCB layout verification to confirm footprint compatibility and clearance with adjacent components.

Q: What is the impact of different DC resistance values between substitute parts?

A: DC resistance directly affects power dissipation in the inductor. The SPD62R-472M (150mOhm) dissipates less power than the original (180mOhm), improving efficiency. The SPM4015T-4R7M (206.5mOhm) dissipates more power, potentially requiring thermal management review in high-current applications.

Q: Why is the SPD62R-472M recommended over the SPM4015T-4R7M?

A: The SPD62R-472M has active product status, ensuring long-term availability and supply chain reliability. The SPM4015T-4R7M is obsolete, presenting future procurement challenges. Additionally, the SPD62R-472M offers lower DC resistance and higher current rating margin.

Q: Are there temperature range considerations when substituting these parts?

A: The original part operates from -40°C to 105°C. Both substitute parts support extended temperature ranges (-55°C to 125°C for SPD62R-472M and -40°C to 125°C for SPM4015T-4R7M), providing operational margin across the original specification.

Q: What packaging formats are available for the substitute parts?

A: The SPD62R-472M is supplied in Tape & Reel (TR) format. The SPM4015T-4R7M is supplied in Cut Tape (CT) and Digi-Reel® format. Packaging selection depends on production volume and assembly equipment compatibility.

Q: Do the substitute parts maintain RoHS3 compliance?

A: Both substitute parts are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental and regulatory specifications.
