UJB0L223THD Equivalent & Substitute Parts

Part Overview

The UJB0L223THD is a 22000 µF, 5.5 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part is designed for general-purpose applications requiring high capacitance at low voltage ratings with through-hole mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UJB0L223THD is based on the following critical parameters:

• Capacitance Match: 22000 µF (exact match required)
• Voltage Rating: Minimum 5.5 V (higher ratings acceptable for backward compatibility)
• Package Type: Radial, can configuration with through-hole mounting
• Lead Spacing: 0.295" (7.50mm) for PCB compatibility
• Polarization: Polar (electrolytic)

The substitute part 229CKS6R3MRY meets these criteria with a higher voltage rating (6.3 V) and improved specifications, making it suitable for direct replacement in applications where the UJB0L223THD is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The 229CKS6R3MRY is a suitable substitute for the obsolete UJB0L223THD based on the following factors:

• Capacitance Equivalence: Both parts provide 22000 µF, meeting the functional requirement.
• Voltage Compatibility: The 6.3 V rating of the substitute exceeds the 5.5 V requirement, providing adequate margin for circuit operation.
• Package Compatibility: Identical lead spacing (0.295" / 7.50mm) and through-hole mounting ensure PCB compatibility.
• Product Status: The substitute is active and currently available, addressing the obsolescence of the original part.
• Compliance: Both parts maintain REACH Unaffected and EAR99 ECCN classifications.
• Improved Specifications: The substitute offers extended lifetime (2000 Hrs vs. 1000 Hrs @ 85°C) and wider operating temperature range (-40°C to 85°C vs. -25°C to 85°C).

Physical dimensions differ slightly (diameter and height), requiring verification of available PCB space before implementation.

Frequently Asked Questions (FAQ)

Q: Can the 229CKS6R3MRY directly replace the UJB0L223THD on the PCB?

A: Lead spacing is identical at 0.295" (7.50mm), enabling direct mounting. However, the substitute has a larger diameter (0.709" vs. 0.630") and greater height (1.437" vs. 1.319"), requiring confirmation that available board space accommodates these dimensions.

Q: Why is the substitute rated at 6.3 V instead of 5.5 V?

A: Higher voltage ratings provide additional safety margin in circuit operation. A 6.3 V capacitor functions correctly in a 5.5 V application without performance degradation.

Q: What is the difference in tolerance between these parts?

A: The original part specifies -10%, +50% tolerance, while the substitute offers ±20% tolerance. The substitute's tighter tolerance may improve circuit performance consistency.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99). The substitute includes RoHS3 compliance certification, which the original part does not specify.

Q: How do the lifetime ratings compare?

A: The substitute provides 2000 hours at 85°C compared to 1000 hours for the original part, indicating improved thermal endurance and extended operational life in high-temperature environments.
