Engineering Selection Recommendations

For Direct Replacement (Same Voltage - 25V):

EEE-TP1E221AP is the primary recommended substitute. It maintains the 25 V voltage rating, 220 µF capacitance, and identical physical footprint (0.394" Dia, 0.402" height). It is Active status with extended lifetime (3000 Hrs @ 125°C), ROHS3 compliance, and AEC-Q200 qualification for automotive applications. This part provides direct functional equivalence with improved long-term availability.

EEE-TC1E221P and EEE-TG1E221P are alternative 25 V options with Active status and extended temperature range (-40°C ~ 125°C). EEE-TC1E221P offers superior lifetime (3000 Hrs @ 125°C) and lower ESR (150 mOhm @ 100 kHz). EEE-TG1E221P maintains the original height specification (0.402") with 2000 Hrs @ 125°C lifetime.

For Voltage Margin Enhancement (35V or 50V):

EEE-TP1V221AP provides a 35 V upgrade option with identical physical dimensions to the original part (0.402" height), Active status, and extended thermal performance (3000 Hrs @ 125°C). This is suitable for applications requiring increased voltage headroom while maintaining the same PCB footprint.

EEE-FK1H221GP and EEE-FK1H221P offer 50 V ratings with Active status and extended operating temperature range (-55°C ~ 105°C). These parts have slightly increased height (0.413") but maintain the same land size and are suitable for high-reliability automotive applications requiring maximum voltage margin.

Obsolete Part Considerations:

EEE-1HA221P and EEE-1VA221AP/P are Not For New Designs status. While functionally compatible, they should not be selected for new product development. Existing designs using these parts should transition to Active alternatives during the next design revision cycle.

Frequently Asked Questions (FAQ)

Q: Can EEE-TP1E221AP directly replace EEE-1EA221P without PCB modification?

A: Yes. Both parts share identical capacitance (220 µF), voltage rating (25 V), tolerance (±20%), physical diameter (0.394"), and land size (0.406" x 0.406"). The height difference is negligible (0.402" vs. 0.402"), and both use surface mount radial can packaging. No PCB layout changes are required.

Q: What is the difference between EEE-TC1E221P and EEE-TG1E221P?

A: Both are 25 V, 220 µF direct equivalents with Active status. EEE-TC1E221P has lower ESR (150 mOhm @ 100 kHz) and higher ripple current capability (750 mA @ 100 kHz) compared to EEE-TG1E221P (300 mOhm, 270 mA @ 100 kHz). EEE-TC1E221P is preferred for high-ripple-current applications. EEE-TG1E221P maintains the original height specification (0.402").

Q: Can I use a 50 V rated part (EEE-FK1H221GP) in place of the 25 V EEE-1EA221P?

A: Yes, from an electrical standpoint. Higher voltage ratings are acceptable substitutes in circuits designed for lower voltages. However, EEE-FK1H221GP has a slightly increased height (0.413" vs. 0.402"), which must be verified against PCB clearance constraints. The land size remains compatible (0.406" x 0.406").

Q: Why is EEE-1EA221P marked as Not For New Designs?

A: This designation indicates the part is in mature/end-of-life phase. While current inventory exists (1973 pcs), Panasonic recommends transitioning to Active alternatives for new product development to ensure long-term supply continuity. Active equivalents like EEE-TP1E221AP provide identical functionality with extended lifecycle support.

Q: What is the significance of AEC-Q200 qualification?

A: AEC-Q200 is the automotive electronics council qualification standard for capacitors. It certifies the part for automotive applications requiring high reliability. EEE-1EA221P, EEE-TP1E221AP, EEE-FK1H221GP, and most recommended substitutes carry this qualification, ensuring suitability for automotive circuit designs.

Q: Are there height restrictions when substituting with EEE-TC1E221P or EEE-FK1H221GP?

A: EEE-TC1E221P and EEE-FK1H221GP have maximum height of 0.413" compared to the original 0.402". Verify PCB clearance above the component location. If clearance is limited, select EEE-TG1E221P, EEE-TK1E221P, or EEE-TP1E221AP, which maintain the 0.402" height specification.

Q: What does ROHS3 compliance mean versus RoHS Compliant?

A: Both indicate RoHS (Restriction of Hazardous Substances) compliance. ROHS3 represents the current EU RoHS Directive 2011/65/EU standard. RoHS Compliant indicates compliance with earlier RoHS standards. ROHS3 is the current requirement for new designs and represents the most current environmental compliance standard.
