Key Parameters

Substitute Part Grouping Explanation

Substitution of the UJB0L822THD1TO is determined by the following critical parameters:

• Capacitance Value: 8200 µF (exact match required)
• Voltage Rating: Minimum 5.5 V (equal or higher acceptable)
• Polarization: Polar (required for electrolytic type)
• Mounting Type: Through Hole (mechanical compatibility)
• Package Type: Radial, Can (physical form factor)
• Lead Spacing: 0.197" (5.00mm) (PCB footprint compatibility)
• Physical Dimensions: Diameter 0.492" (12.50mm) and height compatibility

The substitute part 6.3ZLQ8200MEFC12.5X25 from Rubycon meets these core substitution criteria with identical capacitance, compatible voltage rating (6.3 V exceeds 5.5 V requirement), matching lead spacing, and equivalent radial can package configuration.

Engineering Selection Recommendations

The 6.3ZLQ8200MEFC12.5X25 from Rubycon is a direct functional substitute for the obsolete UJB0L822THD1TO. Selection is supported by the following factors:

• Product Status: The substitute is Active, ensuring continued availability and supply chain stability, whereas the original part is Obsolete.
• Compliance: The Rubycon part is ROHS3 Compliant, meeting current regulatory requirements for electronic components.
• Electrical Compatibility: The 6.3 V rating exceeds the 5.5 V requirement, providing adequate voltage margin. Capacitance values are identical at 8200 µF.
• Mechanical Fit: Lead spacing and radial can package dimensions are identical, ensuring PCB footprint compatibility.
• Performance Enhancement: The substitute offers superior electrical characteristics including lower impedance (13 mOhms vs. 300 mOhms), higher ripple current capability (3.14 A @ 100 kHz vs. 175 mA), and extended lifetime (6000 Hrs @ 105°C vs. 1000 Hrs @ 85°C).

Physical height difference (27.00mm vs. 22.00mm) must be verified against available PCB clearance in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 6.3ZLQ8200MEFC12.5X25 directly replace the UJB0L822THD1TO on existing PCBs?

A: Yes, for electrical function. The lead spacing (5.00mm) and radial can package are identical, ensuring footprint compatibility. However, the substitute is 5mm taller (27.00mm vs. 22.00mm), requiring verification of vertical clearance in the assembly.

Q: Why is the voltage rating higher on the substitute part?

A: The 6.3 V rating on the Rubycon part exceeds the 5.5 V requirement of the original, providing additional voltage margin. This is acceptable in substitution and does not compromise circuit function when the operating voltage remains at or below 5.5 V.

Q: What is the significance of the impedance difference?

A: The substitute exhibits significantly lower impedance (13 mOhms vs. 300 mOhms), resulting in reduced voltage ripple and improved high-frequency performance. This represents an enhancement over the original part's characteristics.

Q: Are there tolerance differences between these parts?

A: Yes. The original part specifies -10%, +50% tolerance, while the substitute offers ±20% tolerance. The substitute's tighter tolerance may provide more predictable capacitance values in production applications.

Q: What does the Active product status mean for the substitute?

A: Active status indicates the Rubycon part is currently in production and available through distribution channels, ensuring long-term supply availability unlike the Obsolete original part.
