UPW1H221MPD Equivalent & Substitute Parts

Part Overview

The UPW1H221MPD is a 220 µF, 50 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 This component is classified as Not For New Designs, indicating it has been superseded in Nichicon's product portfolio. Finding equivalent and substitute parts is necessary for legacy system maintenance, repair operations, and applications where design flexibility permits component selection from alternative manufacturers or series within the same electrical and mechanical specifications.

Thermal performance: Lifetime rating of 5000 Hrs @ 105°C or greater
Operating temperature range: -55°C ~ 105°C
Mechanical compatibility: Lead spacing (5.00 mm), case diameter, and height must permit direct PCB mounting without modification
Polarization: Polar configuration required
Mounting: Through hole radial package

Engineering Selection Recommendations

For direct PCB replacement without layout modification: Select UPW1H221MPD6 or UPJ1H221MPD (both Nichicon, same 10.00 mm case diameter). These maintain identical lead spacing and case footprint, differing only in height. UPW1H221MPD6 offers lower impedance (90 mOhms vs. 119 mOhms) and improved ripple current handling.

For automotive applications requiring AEC-Q200 compliance: EEU-FC1H221SB (Panasonic FC series, Active status) or ELXZ500ELL221MJ20S (Chemi-Con LXZ series, Active status) are qualified alternatives. Both carry AEC-Q200 certification and 5000 Hrs @ 105°C lifetime. Note: These parts feature 12.50 mm case diameter, requiring PCB layout verification.

For space-constrained designs: EEU-FC1H221S (Panasonic FC series) provides the lowest profile at 15.00 mm height with 12.50 mm case diameter and AEC-Q200 rating.

For legacy systems requiring exact form factor: ELXY500ELL221MJ25S (Chemi-Con LXY series) matches the 10.00 mm case diameter and provides superior impedance performance (73 mOhms) with AEC-Q200 compliance and Active product status.

Not recommended for new applications: UPS1H221MPD carries reduced lifetime rating (2000 Hrs @ 105°C) and higher impedance (180 mOhms), suitable only where thermal stress is minimal and cost is the primary constraint.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a larger case diameter (12.50 mm) in place of the UPW1H221MPD (10.00 mm)?

A: Mechanical compatibility depends on PCB layout. If the original design provides adequate spacing between the 10.00 mm footprint and adjacent components, a 12.50 mm diameter part may fit. However, this requires physical verification. Lead spacing remains constant at 5.00 mm across all substitutes, so through-hole mounting compatibility is maintained. Consult your PCB layout documentation before substitution.

Q: What is the significance of the lifetime rating difference between 5000 Hrs @ 105°C and 3000 Hrs @ 105°C?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature before capacitance degradation reaches 20% of initial value. The UPW1H221MPD specifies 5000 Hrs @ 105°C. EEU-FC1H221 (Panasonic) provides only 3000 Hrs @ 105°C, representing a 40% reduction in thermal endurance. For applications operating continuously near 105°C, this difference is significant. For intermittent or lower-temperature operation, the difference is less critical.

Q: Why do some substitutes carry AEC-Q200 certification while others do not?

A: AEC-Q200 is an automotive industry qualification standard. Parts meeting this standard undergo additional testing for reliability in automotive environments. Nichicon UPW, UPJ, and UPS series lack this certification; Panasonic FC series and Chemi-Con LXY/LXZ series carry AEC-Q200 ratings. If your application requires automotive-grade components, select only AEC-Q200-certified alternatives.

Q: Is impedance (mOhms) a critical parameter for substitution?

A: Impedance affects ripple current handling and voltage regulation performance. The UPW1H221MPD specifies 119 mOhms. Substitutes range from 73 mOhms (ELXY500ELL221MJ25S) to 180 mOhms (UPS1H221MPD). Lower impedance improves transient response and reduces heat generation under ripple current stress. If your circuit operates under high ripple current conditions, select substitutes with impedance equal to or lower than the original part. For general-purpose applications, impedance variation within ±30% is typically acceptable.

Q: What does "Not For New Designs" status mean for the UPW1H221MPD?

A: This designation indicates Nichicon has discontinued the UPW series for new product development. Existing inventory remains available, but the manufacturer recommends migration to current-generation alternatives. For new designs, select Active-status parts such as EEU-FC1H221SB (Panasonic) or ELXZ500ELL221MJ20S (Chemi-Con). For legacy system repairs, the UPW1H221MPD remains functionally valid if inventory is available.

Q: Can I substitute UPS1H221MPD (2000 Hrs @ 105°C) for the UPW1H221MPD (5000 Hrs @ 105°C)?

A: Electrical and mechanical parameters are identical, but thermal endurance is reduced by 60%. This substitution is acceptable only in applications where the capacitor operates below 80°C or experiences minimal thermal cycling. For systems designed around the 5000 Hrs @ 105°C specification, UPS1H221MPD does not meet the original performance requirement and should be avoided.
