ELL-SFG560MA Equivalent & Substitute Parts

Part Overview

The ELL-SFG560MA is a 56 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 330 mA continuous current with 1.3Ω DC resistance. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The part operates at 100 kHz inductance test frequency and is packaged in a nonstandard surface mount configuration measuring 4.00mm × 4.00mm.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELL-SFG560MA is determined by the following critical parameters:

• Inductance Value: 56 µH at 100 kHz test frequency (±20% tolerance acceptable)
• Current Rating: Minimum 330 mA continuous current capability
• Saturation Current: Minimum 290 mA Isat
• DC Resistance: Maximum 1.3Ω (lower values preferred for reduced power dissipation)
• Shielding: Shielded construction required
• Mounting: Surface mount configuration
• Package Compatibility: Physical dimensions and height constraints

The substitute part VLCF5028T-560MR43-2 meets these criteria with equivalent inductance, higher current rating (430 mA), improved DC resistance (410 mΩ maximum), and compatible surface mount packaging.

Engineering Selection Recommendations

The VLCF5028T-560MR43-2 (TDK Corporation) is a qualified substitute for the obsolete ELL-SFG560MA based on the following factors:

• Electrical Equivalence: Identical inductance value (56 µH) and tolerance (±20%) at the specified test frequency (100 kHz)
• Performance Margin: Current rating and saturation current exceed the original part requirements, providing operational headroom
• Improved Characteristics: DC resistance is significantly lower (410 mΩ vs. 1.3Ω), reducing power dissipation and heat generation
• Active Production Status: The substitute is currently manufactured and stocked, ensuring long-term availability
• Regulatory Compliance: ROHS3 certification confirms compliance with current environmental standards
• Physical Considerations: The substitute has a larger footprint (5.00 × 5.00 mm vs. 4.00 × 4.00 mm) and greater height (2.80 mm vs. 1.20 mm), requiring PCB layout verification

Frequently Asked Questions (FAQ)

Q: Can VLCF5028T-560MR43-2 be used as a direct replacement for ELL-SFG560MA?

A: Electrical substitution is valid. The inductance value, tolerance, and test frequency are identical. However, the larger package footprint (5.00 × 5.00 mm) and increased height (2.80 mm) require PCB layout modification. Verify available board space before implementation.

Q: What is the significance of the lower DC resistance in the substitute part?

A: The VLCF5028T-560MR43-2 has 410 mΩ maximum DC resistance compared to 1.3Ω in the original part. This represents a 68% reduction in resistive losses, resulting in lower power dissipation, reduced thermal generation, and improved circuit efficiency.

Q: Are both parts suitable for the same operating temperature range?

A: The ELL-SFG560MA does not specify an operating temperature range. The VLCF5028T-560MR43-2 operates from −40°C to 105°C. Verify the original design's temperature requirements before substitution.

Q: What is the impact of the higher saturation current rating?

A: The substitute part has a saturation current of 430 mA compared to 290 mA in the original. This provides additional margin against saturation-induced inductance degradation and is beneficial for circuit reliability.

Q: Does packaging format affect substitution?

A: The original part is supplied in nonstandard packaging; the substitute is supplied in Tape & Reel (TR) format. This affects procurement and assembly processes but does not impact electrical performance.
