ELL-6SH221M Equivalent & Substitute Parts

Part Overview

The ELL-6SH221M is a 220 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 280 mA with 1.4Ohm DC resistance. This component is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support. The part operates at 100 kHz test frequency and is housed in a nonstandard surface mount package measuring 6.40mm × 6.00mm with a maximum seated height of 3.30mm. ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1) ensure compatibility with modern manufacturing standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELL-6SH221M are selected based on strict electrical and mechanical compatibility criteria. All substitute inductors maintain the core electrical specifications: 220 µH inductance at ±20% tolerance (with one exception noted), 100 kHz test frequency, shielded construction, and surface mount configuration. Mechanical compatibility is determined by package dimensions and height constraints within the nonstandard category. All listed substitutes are ROHS3 compliant with MSL 1 rating, ensuring manufacturing process compatibility.

The substitution logic prioritizes:

• Identical inductance value (220 µH)
• Inductance tolerance within ±20% to ±30% range
• Current rating equal to or exceeding 280 mA
• DC resistance comparable to or lower than 1.4Ohm
• Shielded wirewound or drum core construction
• Surface mount nonstandard package format
• 100 kHz test frequency alignment

Engineering Selection Recommendations

For applications requiring direct replacement of the obsolete ELL-6SH221M, the B82462G4224M000 (EPCOS - TDK Electronics) and SRR5028-221Y (Bourns Inc.) are the primary candidates. Both maintain compact form factors with heights of 3.00mm, matching the original package constraints. The B82462G4224M000 offers superior current rating (350 mA) and lower DC resistance (1.35Ohm Max) with AEC-Q200 certification and extended operating temperature range (-55°C ~ 150°C), making it suitable for automotive and industrial applications. The SRR5028-221Y provides the smallest footprint (5.80mm × 5.80mm) with active product status and adequate current margin (300 mA).

The IDCS5020ER221M (Vishay Dale) and SLF7045T-221MR40-H (TDK Corporation) are secondary options. The IDCS5020ER221M delivers the highest current rating (450 mA) and lowest DC resistance (800mOhm Max) but requires larger board space (12.95mm × 9.40mm × 5.08mm height). The SLF7045T-221MR40-H carries AEC-Q200 certification and moderate current rating (400 mA) but is designated "Not For New Designs," limiting its suitability for new product development.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the ELL-6SH221M be directly replaced with any of these substitutes?

A: Direct replacement depends on circuit board layout and thermal constraints. The B82462G4224M000 and SRR5028-221Y offer the closest dimensional compatibility with 3.00mm maximum heights. The IDCS5020ER221M and SLF7045T-221MR40-H require larger board footprints and may necessitate layout modifications.

Q: What is the significance of inductance tolerance differences?

A: The ELL-6SH221M, B82462G4224M000, IDCS5020ER221M, and SLF7045T-221MR40-H all maintain ±20% tolerance, ensuring equivalent circuit performance. The SRR5028-221Y operates at ±30% tolerance, which may impact precision-dependent applications but remains acceptable for general filtering and energy storage functions.

Q: How do DC resistance differences affect circuit performance?

A: Lower DC resistance reduces power dissipation and heat generation. The IDCS5020ER221M (800mOhm Max) and SLF7045T-221MR40-H (996mOhm Max) dissipate less power than the original ELL-6SH221M (1.4Ohm). The B82462G4224M000 (1.35Ohm Max) and SRR5028-221Y (1.25Ohm Max) provide comparable performance with minimal efficiency differences.

Q: Are all substitutes suitable for automotive applications?

A: The B82462G4224M000 and SLF7045T-221MR40-H carry AEC-Q200 certification, meeting automotive reliability standards. The IDCS5020ER221M and SRR5028-221Y lack this certification and should be evaluated against specific automotive qualification requirements.

Q: What packaging format do these substitutes use?

A: All substitute parts are supplied in Tape & Reel (TR) packaging for automated assembly, except where noted. All maintain surface mount configuration compatible with standard pick-and-place equipment.

Q: Can the SLF7045T-221MR40-H be used in new designs?

A: The SLF7045T-221MR40-H is designated "Not For New Designs" by TDK Corporation. While electrically functional, it is not recommended for new product development. The B82462G4224M000, IDCS5020ER221M, and SRR5028-221Y carry "Active" status and are appropriate for new designs.
