Key Parameters

Substitute Part Grouping Explanation

Substitution of the SC53LC-150 is determined by the following critical parameters:

• Inductance value of 15 µH with ±20% tolerance
• Current rating minimum of 1.6 A continuous operation
• Saturation current (Isat) of 1.05 A or higher
• DC resistance not exceeding 126 mOhm
• Shielded construction for EMI containment
• Surface mount configuration with nonstandard package dimensions
• Operating temperature range of -40°C to 125°C minimum
• ROHS3 compliance and MSL 1 rating

The B82472G4153M000 qualifies as a substitute based on matching inductance, tolerance, shielding, mounting type, compliance certifications, and operating temperature range. Variations in current rating, saturation current, and DC resistance remain within acceptable engineering margins for equivalent circuit performance.

Parameter Comparison

Engineering Selection Recommendations

Selection between SC53LC-150 and B82472G4153M000 is based on the following engineering criteria:

The SC53LC-150 is the primary component with Active product status and established supply availability (779 pcs in stock). The B82472G4153M000 serves as an equivalent substitute with Active product status and higher inventory levels (1814 pcs in stock).

Both components maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The B82472G4153M000 provides an extended lower operating temperature limit (-55°C versus -40°C), which may be advantageous in applications requiring broader thermal performance.

Physical dimensions differ between the two parts. The B82472G4153M000 is larger (7.30mm x 7.30mm versus 5.30mm x 5.30mm) with increased seated height (4.60mm versus 3.00mm). PCB layout and clearance requirements must be evaluated before substitution.

Current rating of the B82472G4153M000 is 1.4 A compared to 1.6 A for the SC53LC-150. Applications operating at or near the 1.6 A rating require verification that the substitute part meets circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can B82472G4153M000 be used as a direct replacement for SC53LC-150?

A: Both parts share identical inductance (15 µH), tolerance (±20%), shielding, mounting type, and compliance certifications. However, the B82472G4153M000 has a lower current rating (1.4 A versus 1.6 A) and larger physical dimensions (7.30mm x 7.30mm versus 5.30mm x 5.30mm). Substitution is valid only if circuit current requirements do not exceed 1.4 A and PCB layout accommodates the larger footprint and increased height.

Q: What are the key differences in electrical performance?

A: The primary electrical differences are current rating (1.6 A versus 1.4 A) and saturation current (1.05 A versus 1.1 A). DC resistance is comparable (126 mOhm Max versus 120 mOhm Max). Inductance value and tolerance are identical at 15 µH ±20%.

Q: Are there package or mounting compatibility issues?

A: Both components are surface mount with nonstandard packages. The B82472G4153M000 has larger lateral dimensions (7.30mm x 7.30mm) and greater seated height (4.60mm) compared to the SC53LC-150 (5.30mm x 5.30mm, 3.00mm height). PCB design must accommodate these dimensional differences.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SC53LC-150 and B82472G4153M000 are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). Both are rated for ECCN EAR99 export classification.

Q: What is the operating temperature range difference?

A: The SC53LC-150 operates from -40°C to 125°C. The B82472G4153M000 extends the lower temperature limit to -55°C while maintaining the same upper limit of 125°C. This provides additional thermal margin for low-temperature applications.
