Equivalent & Substitute Parts for UKL2A151KHD1TO

Part Overview

The UKL2A151KHD1TO is a 150 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 This component is classified as Not For New Designs, indicating it has been superseded in Nichicon's product portfolio. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C, making it suitable for general-purpose applications requiring stable capacitance and moderate ripple current handling.

Finding equivalent substitute parts is necessary due to the product's obsolescence status and potential supply constraints. Substitute parts must maintain functional compatibility while meeting or exceeding the electrical and mechanical specifications of the original component.

Frequently Asked Questions (FAQ)

Q: Can the UCY2C151MHD91TO be used as a direct replacement for the UKL2A151KHD1TO?

A: Yes. Both components share identical capacitance (150 µF), tolerance (±20%), physical dimensions (0.492" diameter × 1.043" height), lead spacing (5.00mm), and mounting configuration (radial through-hole). The substitute part is electrically and mechanically compatible without requiring circuit board modifications.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating (100 V vs. 160 V), operating temperature range (-40°C ~ 85°C vs. -40°C ~ 105°C), and lifetime rating (2000 hours @ 85°C vs. 12000 hours @ 105°C). The substitute part provides enhanced performance across all these parameters.

Q: Does the higher voltage rating of the substitute part affect circuit operation?

A: No. A capacitor with a higher voltage rating operates normally at lower voltages. The 160 V rating of the substitute part provides additional safety margin when used in circuits designed for 100 V operation.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant. The UCY2C151MHD91TO is REACH Affected, while the UKL2A151KHD1TO is REACH Unaffected. Verify REACH compliance requirements for your specific application and region.

Q: What is the impact of the extended temperature range on part selection?

A: The substitute part's extended operating range (-40°C ~ 105°C) accommodates applications with higher ambient temperatures or thermal stress. If your application operates within the original part's range (-40°C ~ 85°C), both parts are suitable; however, the substitute provides additional thermal margin.

Q: How does the improved ripple current rating affect reliability?

A: Higher ripple current capacity reduces internal heating and stress on the component during operation. The substitute part's enhanced ripple current ratings (760 mA @ 120 Hz and 1.52 A @ 100 kHz) indicate improved thermal performance and extended operational life under ripple current conditions.
