Substitute Part Grouping Explanation

Substitution for the EEE-FC1V2R2R is determined by the following criteria:

Primary Substitution Parameters:

Capacitance: 2.2 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 35 V minimum (equal or higher voltage acceptable)
Package Type: Radial, Can - SMD (physical and electrical compatibility)
Physical Dimensions: 0.157" Dia (4.00mm), Height ≤ 0.228" (5.80mm)
Surface Mount Land Size: 0.169" L x 0.169" W (4.30mm x 4.30mm)
Operating Temperature: -40°C ~ 105°C minimum
Polarization: Polar (required for electrolytic capacitors)
Mounting Type: Surface Mount

Secondary Compatibility Factors:

AEC-Q200 automotive rating (preferred for automotive applications)
RoHS compliance status
Impedance characteristics (lower impedance preferred for ripple current performance)

Substitute parts are grouped into two categories: direct equivalents (same voltage rating) and upgraded alternatives (higher voltage rating with same or better performance characteristics).

Engineering Selection Recommendations

Direct Equivalent (Same Voltage, Same Lifetime):

EEE-FC1V2R2AR: Panasonic equivalent with identical electrical and physical specifications. Packaging differs (Tape & Reel). Suitable for direct substitution in existing designs.

Upgraded Alternatives (Higher Voltage Rating):

EEE-FC1H2R2R: Panasonic 50 V upgrade within FC series. Maintains 1000-hour lifetime and identical physical dimensions. Higher voltage rating provides additional design margin. Impedance increases to 5 Ohms; ripple current capacity reduces to 22.5 mA @ 120 Hz.
EEE-HA1H2R2R / EEE-HA1H2R2AR: Panasonic HA series, 50 V rating, 1000-hour lifetime. Physical dimensions identical. Lower ripple current specification (16 mA @ 120 Hz) indicates different internal design.

Active Product Alternatives (Extended Lifetime):

EEE-HB1H2R2R / EEE-HB1H2R2AR: Panasonic HB series, currently active products. 50 V rating with extended 2000-hour lifetime at 105°C. Height increases to 0.228" (5.80mm); verify PCB layout clearance. ROHS3 compliant. Recommended for new designs requiring legacy pin compatibility.

Cross-Manufacturer Alternative:

UWG1V2R2MCL1GB: Nichicon UWG series, 35 V rating matching original voltage. Active product status with ROHS3 compliance. Identical physical dimensions and impedance (3 Ohms). Operating temperature range extends to -55°C. Suitable for applications requiring non-Panasonic sourcing or supply chain diversification.

Frequently Asked Questions (FAQ)

Q: Can I use a 50 V rated capacitor in place of the 35 V EEE-FC1V2R2R? A: Yes. Higher voltage ratings are electrically compatible and provide additional design margin. The 50 V alternatives (EEE-FC1H2R2R, EEE-HA series, EEE-HB series) maintain the same 2.2 µF capacitance and ±20% tolerance. Verify that increased height (up to 0.228" for HB series) does not conflict with PCB layout constraints.

Q: What is the difference between EEE-FC1V2R2R and EEE-FC1V2R2AR? A: Both parts are electrically and physically identical. The difference is packaging: EEE-FC1V2R2R is supplied in Tape & Reel (TR) format, while EEE-FC1V2R2AR is also Tape & Reel. Both are classified as "Not For New Designs."

Q: Why should I consider EEE-HB1H2R2R over other substitutes? A: The EEE-HB1H2R2R is an active Panasonic product with extended 2000-hour lifetime at 105°C (double the original 1000 hours). It carries ROHS3 compliance and maintains the same 2.2 µF, 50 V specifications. The 0.228" height is slightly taller; confirm PCB clearance before selection.

Q: Is the Nichicon UWG1V2R2MCL1GB a suitable substitute? A: Yes, for applications requiring cross-manufacturer sourcing. It matches the original 35 V voltage rating and 2.2 µF capacitance with identical physical dimensions and impedance. It is an active product with ROHS3 compliance and extended operating temperature range (-55°C to 105°C).

Q: What happens to ripple current performance when upgrading to 50 V alternatives? A: Ripple current capacity varies by series. EEE-FC1H2R2R reduces to 22.5 mA @ 120 Hz (from 45 mA). EEE-HA and EEE-HB series specify 16 mA @ 120 Hz. Verify that your circuit's ripple current requirements do not exceed the substitute part's rating.

Q: Are all substitute parts AEC-Q200 rated? A: All Panasonic substitutes listed carry AEC-Q200 automotive qualification. The Nichicon UWG1V2R2MCL1GB also carries AEC-Q200 rating. Confirm AEC-Q200 compliance if your application requires automotive-grade components.

Q: Can I mix packaging formats (Tape & Reel vs. Cut Tape) in production? A: Packaging format affects supply chain logistics and assembly line compatibility but does not alter electrical or physical performance. Verify that your assembly equipment supports the selected packaging format before procurement.
