Substitute Part Grouping Explanation

Substitute parts for the EEF-LR0D221R are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Capacitance: 220 µF (exact match required)
• Voltage Rating: 2 V (exact match required)
• Tolerance: ±20% (exact match required)
• Type: Polymer (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• ESR: 4.5 mOhm (exact match required)
• Lifetime @ Temperature: 2000 Hrs @ 105°C (exact match required)

The EEF-SR0D221R4 meets all critical substitution parameters and is classified as a parametric equivalent.
