Nichicon UTT1V100MDD Equivalent & Substitute Parts

Part Overview

The Nichicon UTT1V100MDD is a 10 µF, 35 V aluminum electrolytic capacitor in radial, can package configuration designed for general purpose applications. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing procurement and system maintenance. The UTT series has been superseded by newer product lines, making substitute part identification critical for design continuity and component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Nichicon UTT1V100MDD is determined by strict equivalence across the following parameters:

• Capacitance value: 10 µF (exact match required)
• Voltage rating: 35 V (minimum acceptable)
• Tolerance: ±20% (electrical performance tolerance)
• Package configuration: Radial, can format
• Mounting method: Through hole
• Lead spacing: 0.079" (2.00 mm)
• Physical diameter: 0.197" (5.00 mm)
• Compliance: ROHS3 compliant

The Nichicon UPW1V100MDD meets all substitution criteria. Both components share identical capacitance, voltage rating, tolerance, lead spacing, and diameter specifications. Both are ROHS3 compliant and rated for through-hole mounting in radial can packages.

Parameter Comparison

Engineering Selection Recommendations

The Nichicon UPW1V100MDD is a direct functional substitute for the obsolete UTT1V100MDD. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Physical compatibility is confirmed for standard through-hole PCB layouts with 0.079" (2.00 mm) lead spacing and 0.197" (5.00 mm) diameter footprints. The UPW1V100MDD exhibits increased height (0.433" vs. 0.276"), which must be evaluated against available PCB clearance in the target application.

The UPW series demonstrates superior electrical performance characteristics, including lower impedance (600 mOhms vs. 4 Ohms) and higher ripple current capacity at both low and high frequencies. The extended operating temperature range (-55°C to 105°C vs. -40°C to 105°C) provides broader environmental compatibility.

The reduced lifetime specification of the UPW1V100MDD (2000 Hrs @ 105°C vs. 5000 Hrs @ 105°C) must be assessed against application duty cycle and expected service life requirements.

Frequently Asked Questions (FAQ)

Q: Can the UPW1V100MDD be used as a direct replacement for the UTT1V100MDD?

A: Yes. Both components share identical capacitance (10 µF), voltage rating (35 V), tolerance (±20%), lead spacing (0.079"), and diameter (0.197"). Physical mounting compatibility is confirmed for through-hole PCB applications. Height difference (0.433" vs. 0.276") must be verified against available clearance.

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

A: Primary differences include component height, lifetime rating, impedance, and ripple current capacity. The UPW1V100MDD is taller, has lower impedance, supports higher ripple currents, but has a reduced lifetime specification at 105°C.

Q: Are both parts compliant with current regulations?

A: Yes. Both the UTT1V100MDD and UPW1V100MDD are ROHS3 compliant and REACH unaffected, meeting current electronic component regulatory standards.

Q: Does the height difference affect PCB layout compatibility?

A: The UPW1V100MDD is 0.157" (4.00 mm) taller than the UTT1V100MDD. PCB clearance above the component must be verified to ensure no interference with other board-level components or enclosure constraints.

Q: Which part should be selected for new designs?

A: The UPW1V100MDD is the recommended selection for new designs, as the UTT series is obsolete. The UPW series offers improved electrical performance and broader environmental operating range.
