Nichicon USF1V100MDD Equivalent & Substitute Parts

Part Overview

The Nichicon USF1V100MDD is a 10 µF, 35 V aluminum electrolytic capacitor in radial, can package with through-hole mounting. This component is classified as obsolete, making substitute parts necessary for ongoing production and maintenance applications. The USF series offers a 1000-hour lifetime rating at 105°C with general-purpose applications across industrial and consumer electronics.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the USF1V100MDD is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Capacitance: 10 µF
• Voltage Rating: 35 V (or higher)
• Tolerance: ±20%
• Polarization: Polar
• Operating Temperature: -55°C ~ 105°C
• Lead Spacing: 0.079" (2.00mm)
• Diameter: 0.197" (5.00mm)

Acceptable Variations:

• Lifetime @ 105°C: 1000 Hrs or greater
• Height: Physical height may vary within board layout constraints
• Mounting Type: Through-hole only (surface mount variants listed separately)
• Impedance: Variation acceptable within electrical performance requirements
• Ripple Current: Variation acceptable based on application requirements

Substitute parts are grouped into two categories: direct Nichicon series replacements (UPS1V100MDD, UPM1H100MDD, UPW1V100MDD) and cross-manufacturer equivalents (EKMA350ELL100ME07D from Chemi-Con). The UWT1V100MCL1GB represents a surface-mount variant for applications requiring SMD technology.

Parameter Comparison

Engineering Selection Recommendations

For Through-Hole Applications (Direct Replacement):

UPS1V100MDD and UPW1V100MDD are preferred substitutes for the USF1V100MDD. Both maintain the 10 µF / 35 V specification with identical lead spacing and diameter. These parts offer extended lifetime ratings (2000 Hrs @ 105°C versus 1000 Hrs), providing improved reliability. UPW1V100MDD presents a height advantage at 0.433" compared to UPS1V100MDD at 0.492", making it suitable for space-constrained layouts while maintaining full electrical compatibility.

UPM1H100MDD is a higher voltage variant (50 V) suitable for applications requiring voltage margin above the 35 V specification. The extended 2000-hour lifetime and AEC-Q200 automotive rating provide additional qualification for demanding environments.

EKMA350ELL100ME07D from Chemi-Con offers parametric equivalence with matching 10 µF / 35 V / 1000 Hrs specifications and identical physical dimensions (0.315" height). This cross-manufacturer option is ROHS3 compliant and suitable for applications where multi-source qualification is required.

For Surface-Mount Applications:

UWT1V100MCL1GB is the only surface-mount variant listed. This part maintains electrical specifications (10 µF / 35 V / ±20%) with reduced height (0.213") and SMD land size (5.30mm x 5.30mm). This component is active status and suitable for modern PCB designs requiring surface-mount technology.

Compliance Considerations:

All listed substitutes maintain ROHS3 compliance and REACH unaffected status, matching the original part's regulatory standing. Selection should prioritize parts with active product status (UWT1V100MCL1GB) where available for new designs, while obsolete alternatives remain valid for legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can UPM1H100MDD replace USF1V100MDD in a 35 V circuit?

A: Yes. UPM1H100MDD is rated for 50 V, which exceeds the 35 V requirement. The higher voltage rating provides additional safety margin without affecting circuit operation. All other critical parameters (10 µF capacitance, ±20% tolerance, -55°C ~ 105°C operating range, 2.00mm lead spacing, 5.00mm diameter) match the original specification.

Q: What is the height difference between substitute parts, and does it matter?

A: USF1V100MDD height is 0.315" (8.00mm). UPS1V100MDD measures 0.492" (12.50mm), UPW1V100MDD measures 0.433" (11.00mm), and EKMA350ELL100ME07D matches at 0.315" (8.00mm). Height variation affects PCB layout and clearance. For space-constrained designs, UPW1V100MDD or EKMA350ELL100ME07D are preferred. Verify board layout constraints before selection.

Q: Is UWT1V100MCL1GB a direct replacement for through-hole applications?

A: No. UWT1V100MCL1GB is a surface-mount variant with different mounting technology and land pattern (5.30mm x 5.30mm). It is suitable only for PCBs designed for SMD components. For through-hole boards, select UPS1V100MDD, UPW1V100MDD, or EKMA350ELL100ME07D.

Q: Why are some substitutes rated for 2000 hours instead of 1000 hours?

A: Extended lifetime ratings (2000 Hrs @ 105°C) indicate improved capacitor design and materials. These parts provide longer operational life under thermal stress. Selection of extended-lifetime variants is optional and depends on application reliability requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original USF1V100MDD regulatory classification.

Q: Can I use a substitute with different ripple current rating?

A: Ripple current specifications vary among substitutes based on internal design. Selection must account for actual circuit ripple current requirements. Verify that the selected substitute's ripple current rating meets or exceeds the application's ripple current demand at both low frequency (120 Hz) and high frequency (100 kHz or 10 kHz).
