Nichicon UTS1E101MPD Equivalent & Substitute Parts

Part Overview

The Nichicon UTS1E101MPD is a 100 µF, 25 V aluminum electrolytic capacitor in radial, can package configuration rated for 5000 hours at 105°C. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and component procurement. The UTS series represents a legacy product line, and modern alternatives from both Nichicon and other manufacturers provide equivalent electrical performance with improved availability and compliance certifications.

Substitute Part Grouping Explanation

Substitution for the UTS1E101MPD is determined by strict equivalence across the following critical parameters: capacitance (100 µF), tolerance (±20%), rated voltage (25 V), operating temperature range (-40°C to 105°C), polarization (polar), and through-hole radial mounting configuration. Parts are grouped into two categories based on lifetime rating at 105°C:

Category A - Full Lifetime Equivalents (5000 Hrs @ 105°C): UHE1E101MED, UHV1E101MED, EEU-EB1E101S, EEU-EB1E101SB, EEU-EB1E101SH, EEU-FR1E101. These parts maintain identical thermal endurance specifications.

Category B - Reduced Lifetime Alternatives: UHD1E101MED (2000 Hrs @ 105°C), UKL1E101MPDANA (1000 Hrs @ 105°C), EEU-FM1E101, EEU-FM1E101B (2000 Hrs @ 105°C). These parts provide electrical equivalence but with lower thermal lifetime ratings, suitable for applications with reduced thermal stress requirements.

Physical dimensions and lead spacing vary among substitutes. The original UTS1E101MPD features 0.138" (4.60mm) lead spacing and 0.354" (9.00mm) maximum height. Substitutes with matching lead spacing (0.138") include UKL1E101MPDANA. Substitutes with 0.098" (2.50mm) lead spacing include UHE1E101MED, UHV1E101MED, EEU-EB1E101S, EEU-EB1E101SH, EEU-FR1E101. Substitutes with 0.197" (5.00mm) lead spacing include EEU-EB1E101SB, EEU-FM1E101B.

Engineering Selection Recommendations

For applications requiring direct replacement of the UTS1E101MPD with identical thermal lifetime specifications (5000 Hrs @ 105°C), select from the following active or readily available parts: EEU-EB1E101S, EEU-EB1E101SB, EEU-EB1E101SH (Panasonic EB-A series, all active status), or UHE1E101MED (Nichicon UHE series, obsolete but high inventory). All maintain ROHS3 compliance and REACH unaffected status.

For applications where lead spacing must match the original 0.138" (4.60mm) configuration, UKL1E101MPDANA provides the closest physical compatibility, though it carries a reduced 1000-hour lifetime rating and "Not For New Designs" status.

For new designs, prioritize active-status parts from the Panasonic EB-A series (EEU-EB1E101S, EEU-EB1E101SB, EEU-EB1E101SH) or Panasonic FR-A series (EEU-FR1E101). These offer full compliance certifications, active product status, and guaranteed long-term availability.

Applications with reduced thermal stress may utilize 2000-hour lifetime alternatives: Panasonic EEU-FM1E101 or EEU-FM1E101B (active status), or Nichicon UHD1E101MED (obsolete but high inventory). These parts provide higher ripple current ratings and lower impedance in some cases.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different lead spacing than the original UTS1E101MPD?

A: Lead spacing affects PCB layout and component placement. The original UTS1E101MPD uses 0.138" (4.60mm) spacing. Substitutes with 0.098" (2.50mm) or 0.197" (5.00mm) spacing require PCB redesign. If PCB modification is not feasible, UKL1E101MPDANA maintains the original 0.138" spacing, though with reduced lifetime rating.

Q: What is the difference between 5000-hour and 2000-hour lifetime ratings?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation reaches specified limits. A 5000-hour part maintains performance twice as long as a 2000-hour part under identical thermal conditions. Selection depends on application duty cycle and expected service life.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts carry ROHS3 compliance certification. The original UTS1E101MPD is REACH unaffected. All substitutes maintain REACH unaffected status, ensuring regulatory compatibility across both legacy and modern supply chains.

Q: Which substitute offers the best ripple current performance?

A: Ripple current capacity varies by series. EEU-FM1E101 and EEU-FM1E101B (Panasonic FM-A series) provide the highest ripple current ratings at 318.5 mA @ 120 Hz and 455 mA @ 100 kHz. UHV1E101MED offers 450 mA @ 100 kHz. EEU-EB series parts provide lower ripple current (95 mA @ 120 Hz, 124.6 mA @ 100 kHz) but maintain 5000-hour lifetime.

Q: Can I substitute an obsolete Nichicon part with an active Panasonic part?

A: Yes. Panasonic EEU-EB1E101S, EEU-EB1E101SB, EEU-EB1E101SH, EEU-FM1E101, EEU-FM1E101B, and EEU-FR1E101 all provide electrical and thermal equivalence with active product status, ensuring long-term availability and supply chain stability.

Q: What is the impedance difference between substitutes?

A: Impedance values are provided for specific series. UHE1E101MED specifies 220 mOhms, UHV1E101MED specifies 100 mOhms, and EEU-FM series parts specify 130 mOhms. Lower impedance generally indicates better high-frequency performance. Impedance data is not provided for all parts in the comparison set.
