Nichicon UVR2W220MHA Equivalent & Substitute Parts

Part Overview

The Nichicon UVR2W220MHA is a 22 µF, 450 V aluminum electrolytic capacitor in radial, can package format with a rated lifetime of 2000 hours at 85°C. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The UVR series represents legacy technology; modern designs should transition to active product lines with improved thermal performance and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can I use a 500 V rated capacitor in place of the 450 V UVR2W220MHA? A: Yes. A higher voltage rating is a valid substitution provided all other parameters match. Parts UCY2H220MHD6 and 500BXC22M16X25 are 500 V alternatives that maintain 22 µF capacitance and compatible mechanical dimensions.

Q: What is the difference between "Obsolete" and "Not For New Designs" product status? A: Obsolete parts are no longer manufactured and existing inventory is limited. "Not For New Designs" indicates the manufacturer has discontinued the product line but may still produce limited quantities. For new designs, select Active status parts such as UBT2W220MHD8, 226CKS450M, or ESMG451ELL220ML25S.

Q: Does the operating temperature range affect substitution compatibility? A: The operating temperature range does not restrict substitution if the application operates within the substitute part's range. If your application operates at 85°C, parts rated to -25°C ~ 85°C, -25°C ~ 105°C, or -25°C ~ 130°C are all acceptable. Extended temperature ranges provide design margin.

Q: Are all substitute parts ROHS3 compliant? A: All listed substitute parts are ROHS3 compliant. The original UVR2W220MHA is RoHS non-compliant. If RoHS compliance is required, any substitute part listed meets this requirement.

Q: What does "Lifetime @ Temperature" mean, and how does it affect part selection? A: Lifetime at temperature specifies the expected operational life under rated ripple current at a given temperature. The UVR2W220MHA is rated 2000 Hrs @ 85°C. Substitutes with longer lifetimes (10000 Hrs, 12000 Hrs) provide extended service life and design margin. Selection depends on application duty cycle and expected service life requirements.

Q: Can I substitute a part with higher ripple current rating? A: Yes. A higher ripple current rating indicates the capacitor can handle greater AC current stress. This is a safe substitution that provides design margin. Verify the substitute part's ripple current meets or exceeds your application requirements.

Q: What is the significance of AEC-Q200 rating on the 450RX3022M16X25? A: AEC-Q200 is an automotive qualification standard. The 450RX3022M16X25 is qualified for automotive applications with extended temperature operation to 130°C. This part is suitable for automotive and high-reliability applications requiring automotive-grade components.

Q: Are mechanical dimensions identical across all substitute parts? A: Lead spacing (0.295") and case diameter (0.630") are identical across all substitutes, ensuring PCB footprint compatibility. Height varies slightly (1.043" to 1.063"), but all parts fit within standard through-hole mounting envelopes. Verify height clearance in your specific PCB layout if space is constrained.
