ELL-6SH220M Equivalent & Substitute Parts

Part Overview

The Panasonic ELL-6SH220M is a 22 µH shielded wirewound inductor rated for 900 mA with 140mOhm DC resistance, designed for surface mount applications in nonstandard package configurations. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Substitute parts must maintain the core electrical specifications—22 µH inductance at 100 kHz test frequency, shielded construction, and surface mount compatibility—while accommodating variations in current rating, DC resistance, and package dimensions within acceptable engineering tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELL-6SH220M are qualified based on the following criteria:

Core Electrical Parameters (Non-Negotiable):

• Inductance value: 22 µH at 100 kHz test frequency
• Shielded construction
• Surface mount configuration
• RoHS3 compliance

Allowable Variations:

• Current rating: Substitute parts must equal or exceed 900 mA minimum rating
• DC resistance: Substitute parts may vary from the original 140mOhm specification, provided the value is documented and acceptable for the application circuit
• Inductance tolerance: ±20% or ±30% are both acceptable for this product category
• Package dimensions: Nonstandard packages are acceptable if footprint compatibility is verified in the target application

The two substitute parts listed—B82462G4223M000 (EPCOS - TDK Electronics) and SRR5028-220Y (Bourns Inc.)—meet all core electrical requirements and exceed the current rating specification, providing improved performance margins for designs currently using the obsolete ELL-6SH220M.

Parameter Comparison

Engineering Selection Recommendations

B82462G4223M000 (EPCOS - TDK Electronics): This substitute provides a direct functional replacement with improved current rating (1.05 A vs. 900 mA) and extended operating temperature range (-55°C ~ 150°C). The part carries AEC-Q200 automotive qualification, indicating suitability for demanding applications. DC resistance is marginally higher at 150mOhm maximum compared to the original 140mOhm specification. Package dimensions are comparable (6.30mm x 6.30mm vs. 6.40mm x 6.00mm), with reduced height (3.00mm vs. 3.30mm). Active product status ensures long-term availability and supply chain stability.

SRR5028-220Y (Bourns Inc.): This substitute offers the highest current rating (1.15 A) and the lowest DC resistance (120mOhm maximum), providing superior electrical performance characteristics. The inductance tolerance is wider at ±30% compared to ±20%, which may require circuit validation in applications with tight inductance specifications. Operating temperature range is -40°C ~ 125°C. Package dimensions are the smallest of the three options (5.80mm x 5.80mm), with matching height (3.00mm). Active product status and documented Q factor (7 @ 2.52MHz) and self-resonant frequency (20MHz) provide additional design reference data.

Both substitute parts are active products with full RoHS3 compliance and unlimited moisture sensitivity ratings, ensuring regulatory compliance and manufacturing process compatibility with the original ELL-6SH220M.

Frequently Asked Questions (FAQ)

Q: Can B82462G4223M000 or SRR5028-220Y be used as direct drop-in replacements for ELL-6SH220M?

A: Both parts meet the core electrical specifications (22 µH inductance, shielded, surface mount, 100 kHz test frequency). However, package dimensions differ slightly. B82462G4223M000 is closest in footprint (6.30mm x 6.30mm vs. 6.40mm x 6.00mm), while SRR5028-220Y is smaller (5.80mm x 5.80mm). PCB layout verification is required to confirm mechanical compatibility in your specific application.

Q: What is the significance of the current rating difference?

A: The ELL-6SH220M is rated for 900 mA. Both substitutes exceed this rating (B82462G4223M000 at 1.05 A, SRR5028-220Y at 1.15 A), providing additional design margin and thermal headroom. This is advantageous for applications operating near the original current limit.

Q: How do DC resistance variations affect circuit performance?

A: DC resistance directly impacts power dissipation and voltage drop across the inductor. The original ELL-6SH220M specifies 140mOhm. B82462G4223M000 is 150mOhm maximum (10mOhm higher), while SRR5028-220Y is 120mOhm maximum (20mOhm lower). For applications sensitive to inductor losses, SRR5028-220Y offers improved efficiency. Circuit simulation is recommended to quantify the impact on your specific design.

Q: Why does SRR5028-220Y have ±30% inductance tolerance versus ±20%?

A: Inductance tolerance reflects manufacturing process capability and design philosophy. Both tolerances are acceptable for general-purpose inductor applications. Applications requiring tighter inductance control should verify that ±30% tolerance is acceptable for the target circuit function, or select B82462G4223M000 with ±20% tolerance.

Q: Are there temperature range considerations for substitution?

A: The original ELL-6SH220M does not specify an operating temperature range. B82462G4223M000 operates from -55°C to 150°C (wider range), while SRR5028-220Y operates from -40°C to 125°C. For applications requiring extended temperature performance, B82462G4223M000 is the preferred choice. For standard industrial applications, both are suitable.

Q: What does AEC-Q200 qualification on B82462G4223M000 indicate?

A: AEC-Q200 is an automotive industry standard qualification for passive components, indicating the part has undergone rigorous reliability testing and is approved for automotive applications. This certification is not present on SRR5028-220Y. If your application requires automotive-grade components, B82462G4223M000 is the appropriate selection.

Q: How should I verify compatibility before design implementation?

A: Confirm the following: (1) PCB footprint and height clearance accommodate the substitute part dimensions; (2) circuit simulation validates that inductance tolerance and DC resistance variations do not adversely affect circuit performance; (3) thermal analysis confirms that the higher current rating does not introduce thermal management issues; (4) supply chain availability and lead times meet production schedules.
