Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELL-6RH220M are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 22 µH (exact match required)
• Inductance tolerance: ±20% or tighter
• Current rating: minimum 700 mA
• DC resistance: within acceptable operating range for the application
• Shielding: shielded configuration
• Mounting type: surface mount
• Physical dimensions: compatible with 6.40mm x 6.00mm footprint and 2.80mm height constraints
• Compliance: ROHS3 compliant, MSL 1 rating

Two substitute parts meet these criteria: the CDRH62BNP-220MC-B from Sumida America Components Inc. and the SRR5028-220Y from Bourns Inc. Both maintain the 22 µH inductance specification, shielded construction, and surface mount configuration required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

CDRH62BNP-220MC-B (Sumida America Components Inc.) is the primary substitute for the ELL-6RH220M. This part maintains identical inductance and tolerance specifications with a marginally higher current rating of 740 mA. The DC resistance of 340mOhm Max is higher than the original 220mOhm specification but remains within acceptable parameters for most applications. Physical dimensions are slightly larger (6.60mm x 6.20mm vs. 6.40mm x 6.00mm) with a maximum height of 3.00mm compared to 2.80mm. The part is active in production with ROHS3 compliance and unlimited MSL rating. Packaging is available in Tape & Reel format with 13,633 units in stock.

SRR5028-220Y (Bourns Inc.) serves as an alternative substitute with superior electrical performance characteristics. This part offers the highest current rating at 1.15 A and the lowest DC resistance at 120mOhm Max, making it suitable for applications requiring lower power dissipation. The inductance tolerance is ±30%, which is wider than the original ±20% specification. Physical dimensions are the smallest of the three options at 5.80mm x 5.80mm with a maximum height of 3.00mm. The part is active in production with ROHS3 compliance and unlimited MSL rating. Packaging is available in Cut Tape and Digi-Reel format with 16,858 units in stock.

Both substitute parts are ROHS3 compliant and carry MSL 1 ratings, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can the CDRH62BNP-220MC-B directly replace the ELL-6RH220M in existing designs?

A: The CDRH62BNP-220MC-B maintains the same 22 µH inductance and ±20% tolerance as the original part. Physical dimensions are slightly larger (6.60mm x 6.20mm vs. 6.40mm x 6.00mm), requiring verification of PCB layout clearance. The DC resistance increase from 220mOhm to 340mOhm Max will result in higher power dissipation; circuit thermal analysis is necessary to confirm acceptability for your specific application.

Q: What are the key differences between the two substitute parts?

A: The CDRH62BNP-220MC-B provides the closest electrical match with ±20% tolerance identical to the original part. The SRR5028-220Y offers superior current handling (1.15 A vs. 700 mA) and lower DC resistance (120mOhm Max), but features a wider inductance tolerance of ±30%. The SRR5028-220Y also has the smallest footprint at 5.80mm x 5.80mm.

Q: Are there any compliance or storage considerations when switching to substitute parts?

A: Both substitute parts are ROHS3 compliant with MSL 1 ratings, matching the original ELL-6RH220M specifications. No additional handling or storage precautions are required beyond standard surface mount component practices.

Q: How do the physical dimensions affect PCB layout compatibility?

A: The ELL-6RH220M measures 6.40mm x 6.00mm with a maximum height of 2.80mm. The CDRH62BNP-220MC-B is slightly larger at 6.60mm x 6.20mm with 3.00mm height. The SRR5028-220Y is the smallest at 5.80mm x 5.80mm with 3.00mm height. Verify that your PCB layout accommodates these dimensional variations, particularly in height-constrained applications.

Q: Which substitute part should be selected for new production designs?

A: Selection depends on application requirements. For designs requiring the closest electrical match to the original specification, the CDRH62BNP-220MC-B is recommended. For applications benefiting from higher current capacity and lower DC resistance, the SRR5028-220Y is the preferred choice. Both parts are active in production with substantial inventory availability.
