3483-150M Equivalent & Substitute Parts

Part Overview

The 3483-150M is a 15 µH unshielded drum core wirewound inductor manufactured by API Delevan Inc., rated for 1.12 A continuous current with a maximum DC resistance of 130 mOhm. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The part operates across a temperature range of -20°C to 80°C and is mounted as a surface mount device in a nonstandard package measuring 7.30mm × 7.30mm × 4.60mm (height).

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3483-150M is determined by the following critical parameters:

• Inductance Value: Must be 15 µH with ±20% tolerance
• Current Rating: Minimum 930 mA (substitute part rating); original part rated 1.12 A
• DC Resistance: Maximum 180 mOhm (substitute part); original part maximum 130 mOhm
• Core Material: Ferrite, unshielded drum core construction
• Mounting: Surface mount configuration
• Package Footprint: Nonstandard package with compatible physical dimensions

The SDR0603-150ML from Bourns Inc. meets these substitution criteria. Both parts share identical inductance specifications, ferrite core construction, and unshielded drum core design. The substitute part operates at a slightly lower current rating (930 mA vs. 1.12 A) and exhibits higher DC resistance (180 mOhm vs. 130 mOhm), which must be evaluated against specific circuit requirements.

Engineering Selection Recommendations

The SDR0603-150ML is the identified substitute for the obsolete 3483-150M based on matching inductance value, core material, and shielding configuration. The substitute part offers the following advantages:

• Active Product Status: The SDR0603-150ML remains in active production, ensuring long-term availability and supply chain stability.
• Enhanced Compliance: ROHS3 compliance of the substitute part aligns with current regulatory requirements, whereas the original part is RoHS non-compliant.
• Extended Temperature Range: Operating range of -40°C to 125°C exceeds the original part's -20°C to 80°C specification, providing greater thermal margin in applications.
• Improved Packaging: Tape & Reel packaging of the substitute supports automated assembly processes compared to the nonstandard packaging of the original part.

Circuit designers must account for the reduced current rating (930 mA vs. 1.12 A) and increased DC resistance (180 mOhm vs. 130 mOhm) when evaluating substitution feasibility. These parameter differences may impact thermal performance and voltage drop characteristics in the application.

Frequently Asked Questions (FAQ)

Q: Can the SDR0603-150ML directly replace the 3483-150M in all applications?

A: Direct substitution requires verification that the application current does not exceed 930 mA and that the increased DC resistance of 180 mOhm (versus 130 mOhm) is acceptable for the circuit design. The higher resistance will increase power dissipation and voltage drop across the inductor.

Q: What is the physical compatibility between these two parts?

A: Both parts are surface mount inductors with nonstandard packages. The 3483-150M measures 7.30mm × 7.30mm × 4.60mm (height), while the SDR0603-150ML measures 5.80mm × 5.80mm × 3.90mm (height). PCB footprint redesign may be necessary to accommodate the smaller lateral dimensions of the substitute part.

Q: Are there compliance differences between the original and substitute parts?

A: Yes. The 3483-150M is RoHS non-compliant, while the SDR0603-150ML is ROHS3 compliant. For applications subject to RoHS regulations, the substitute part is the appropriate choice.

Q: How do the inductance test frequencies differ between these parts?

A: The 3483-150M inductance is tested at 100 kHz, while the SDR0603-150ML is tested at 1 kHz. This difference in test frequency may result in slight variations in measured inductance values depending on the frequency characteristics of each part.

Q: What is the saturation current of the substitute part?

A: The SDR0603-150ML has a saturation current (Isat) of 1.1 A, which exceeds its continuous current rating of 930 mA. This specification is not provided for the original 3483-150M part.
