UPW2A220MPD Equivalent & Substitute Parts

Part Overview

The UPW2A220MPD is a 22 µF, 100 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as not for new designs, indicating it has been superseded in Nichicon's product line. The UPW series offers a 3000-hour lifetime at 105°C with general-purpose applications including filtering and energy storage in power supply circuits. Identifying equivalent and substitute parts is necessary for legacy system maintenance, repair operations, and design continuity when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the UPW2A220MPD is determined by the following critical parameters:

Capacitance value: 22 µF (exact match required)
Voltage rating: 100 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package type: Radial, Can (exact match required)
Mounting type: Through Hole (exact match required)
Lead spacing: 0.138" (4.60mm) (exact match required for PCB compatibility)
Case diameter: 0.315" (8.00mm) (exact match required for mechanical fit)

Substitute parts may vary in the following parameters without affecting functional compatibility: lifetime rating at 105°C, ripple current specifications, impedance, height, and product status. Parts from different manufacturers meeting all critical parameters are considered direct substitutes.

Engineering Selection Recommendations

All listed substitute parts meet the core electrical specifications (22 µF, 100 V, ±20% tolerance) and mechanical requirements (radial through-hole configuration, 0.315" case diameter, 0.138" lead spacing) for direct replacement of the UPW2A220MPD in standard applications.

For applications requiring active product status and ongoing manufacturer support, the 226KXM100M (Cornell Dubilier), EEU-FC2A220, EEU-FC2A220BJ, and EEU-FC2A220B (Panasonic) are preferred selections. These parts carry active product status and are currently manufactured.

For automotive applications requiring AEC-Q200 certification, select UPM2A220MPD (Nichicon), EEU-FC2A220, EEU-FC2A220BJ, or EEU-FC2A220B (Panasonic).

The EEU-FC2A220B variant features a 0.197" (5.00mm) lead spacing and 0.650" (16.50mm) height, making it incompatible with PCB layouts designed for the standard 0.138" (4.60mm) lead spacing of the UPW2A220MPD. This part is not suitable for direct substitution without PCB modification.

Frequently Asked Questions (FAQ)

Q: Can I use UPS2A220MPD as a substitute for UPW2A220MPD?

A: Yes. The UPS2A220MPD meets all critical electrical and mechanical parameters. The primary difference is a reduced lifetime rating of 2000 hours at 105°C compared to 3000 hours for the UPW2A220MPD. This substitution is acceptable for applications where the lower lifetime rating does not compromise system reliability requirements.

Q: What is the difference between EEU-FC2A220 and EEU-FC2A220BJ?

A: Both parts are Panasonic FC series capacitors with identical electrical specifications. The primary differences are packaging format (EEU-FC2A220 is bulk; EEU-FC2A220BJ is cut tape) and physical height (0.453" versus 0.492"). Both are electrically and mechanically compatible with the UPW2A220MPD.

Q: Why is EEU-FC2A220B listed but not recommended as a direct substitute?

A: The EEU-FC2A220B has a 0.197" (5.00mm) lead spacing, whereas the UPW2A220MPD requires 0.138" (4.60mm) spacing. This dimensional difference makes it incompatible with existing PCB layouts without modification to the pad pattern and trace routing.

Q: Are Nichicon UPJ2A220MPD and UPM2A220MPD interchangeable with UPW2A220MPD?

A: Both parts are electrically and mechanically compatible. The UPJ2A220MPD has a slightly taller profile (0.492" versus 0.453"), and the UPM2A220MPD is rated for automotive applications with AEC-Q200 certification and carries a taller profile (0.512"). Verify clearance in your specific application before substitution.

Q: Can I substitute a part with a lower lifetime rating?

A: Yes, provided the application does not require the full 3000-hour lifetime at 105°C. The UPS2A220MPD and Panasonic FC series parts offer 2000-hour ratings and are suitable for applications with less stringent lifetime requirements.

Q: Is the 226KXM100M from Cornell Dubilier a suitable replacement?

A: Yes. The 226KXM100M meets all critical electrical and mechanical specifications and carries active product status. It is manufactured by Cornell Dubilier / Illinois Capacitor and is currently available.
