Equivalent & Substitute Parts for UJB0L103THD1TO

Part Overview

The Nichicon UJB0L103THD1TO is a 10000 µF, 5.5 V aluminum electrolytic capacitor in radial, can package configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The part is designed for general-purpose applications requiring high capacitance in a compact radial form factor with through-hole mounting.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UJB0L103THD1TO is determined by the following critical parameters:

• Capacitance Value: 10000 µF (exact match required)
• Package Configuration: Radial, can format with through-hole mounting
• Lead Spacing: 0.197" (5.00mm) for PCB compatibility
• Physical Dimensions: 0.492" diameter and compatible height for board layout
• Voltage Rating: Minimum 5.5 V; higher ratings provide design margin
• Polarization: Polar configuration (standard for aluminum electrolytic capacitors)

The Rubycon 6.3ZLQ10000MEFC12.5X35 meets these substitution criteria with identical capacitance, matching package geometry, compatible lead spacing, and higher voltage rating (6.3 V). Physical dimensions remain within acceptable tolerance for direct board replacement.

Parameter Comparison

Engineering Selection Recommendations

The Rubycon 6.3ZLQ10000MEFC12.5X35 is a direct functional substitute for the obsolete Nichicon UJB0L103THD1TO based on matching capacitance, package geometry, and lead spacing. The substitute part offers the following advantages:

• Active Product Status: Currently manufactured and available through distribution channels
• Higher Voltage Rating: 6.3 V rating provides additional design margin over the 5.5 V original specification
• Extended Temperature Range: Operating range of -40°C to 105°C exceeds the original -25°C to 85°C specification
• RoHS3 Compliance: Meets current regulatory requirements
• Improved Reliability: 6000 hours lifetime at 105°C compared to 1000 hours at 85°C for the original part

The substitute part has a maximum seated height of 1.457" (37.00mm) compared to 1.063" (27.00mm) for the original. Board layout verification is required to confirm clearance compatibility in the target application.

Frequently Asked Questions (FAQ)

Q: Can the Rubycon 6.3ZLQ10000MEFC12.5X35 be used as a direct replacement for the Nichicon UJB0L103THD1TO?

A: Yes, for applications where the increased height of 37.00mm does not conflict with board layout constraints. The capacitance, lead spacing, and radial can package are identical. The higher voltage rating (6.3 V vs. 5.5 V) is compatible with circuits designed for the original part.

Q: What is the primary difference between these two parts?

A: The main differences are manufacturer, product status (obsolete vs. active), and physical height. The Rubycon part is 10mm taller and offers superior temperature performance and reliability ratings.

Q: Are there any compatibility concerns with the height difference?

A: The substitute part is taller (37.00mm vs. 27.00mm). Verify that the increased height does not interfere with adjacent components or enclosure constraints in your specific application.

Q: Does the tolerance difference affect substitution?

A: The Rubycon part has ±20% tolerance compared to -10%, +50% for the Nichicon part. Both tolerances are within acceptable ranges for general-purpose capacitor applications. The actual capacitance value will fall within the specified tolerance band for each part.

Q: Is the Rubycon part RoHS compliant?

A: Yes, the Rubycon 6.3ZLQ10000MEFC12.5X35 is ROHS3 compliant, meeting current environmental and regulatory standards.
