Nichicon UTS1H101MPD Equivalent & Substitute Parts

Part Overview

The Nichicon UTS1H101MPD is a 100 µF, 50 V aluminum electrolytic capacitor in radial, can package rated for 5000 hours at 105°C. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute parts must maintain the same capacitance, voltage rating, tolerance, and mechanical compatibility while meeting current availability and compliance requirements.

Substitute Part Grouping Explanation

Substitute parts are grouped based on strict electrical and mechanical compatibility with the UTS1H101MPD. All substitutes maintain the core electrical specifications: 100 µF capacitance, 50 V voltage rating, ±20% tolerance, and -40°C to 105°C operating temperature range. Mechanical compatibility is determined by matching the radial, can package format with 0.315" (8.00mm) diameter and through-hole mounting.

Substitutes are differentiated by three key parameters:

Lifetime Rating: Ranges from 3000 to 7000 hours at 105°C. The original part specifies 5000 hours; substitutes with equal or greater lifetime are direct replacements.
Lead Spacing: Either 0.138" (4.60mm) or 0.197" (5.00mm). Lead spacing affects PCB layout compatibility.
Height: Ranges from 9.00mm to 13.00mm. Height variation impacts board-level clearance and mechanical fit.

All substitute parts listed maintain identical capacitance, voltage, tolerance, polarization, and operating temperature specifications as the original part.

Engineering Selection Recommendations

Direct Electrical Equivalents (5000 Hour Lifetime)

EEU-EB1H101S, EEU-EB1H101SJ, and EEU-EB1H101SB are direct electrical equivalents with matching 5000-hour lifetime ratings. These Panasonic parts are active products with ROHS3 compliance, providing long-term availability and regulatory alignment. Selection between these three depends on lead spacing and packaging requirements: EEU-EB1H101S and EEU-EB1H101SJ use 0.138" (4.60mm) lead spacing matching the original part, while EEU-EB1H101SB uses 0.197" (5.00mm) spacing for wider PCB layouts.

Extended Lifetime Alternatives (6000-7000 Hours)

EEU-FR1H101 and EEU-FR1H101B offer 6000-hour ratings, and UHE1H101MPD offers 7000-hour rating. These parts provide enhanced reliability margins for applications requiring extended operational life. All maintain 0.138" (4.60mm) lead spacing except EEU-FR1H101B, which uses 0.197" (5.00mm) spacing.

Reduced Lifetime Alternatives (3000 Hours)

EEU-FM1H101, EEU-FM1H101B, EEU-FM1H101BJ, and UHD1H101MPD are rated for 3000 hours at 105°C. These parts are suitable for applications with lower thermal stress or shorter operational requirements. All are active products with ROHS3 compliance.

Compliance Considerations

All Panasonic substitutes carry ROHS3 compliance and REACH Affected status. The original UTS1H101MPD is REACH Unaffected. Nichicon alternatives (UHD1H101MPD, UHE1H101MPD) are ROHS3 compliant and REACH Affected. Selection should account for supply chain compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different lead spacing?

A: Lead spacing affects PCB hole positioning. Parts with 0.138" (4.60mm) spacing are direct mechanical replacements for the UTS1H101MPD. Parts with 0.197" (5.00mm) spacing require PCB layout modification and are not direct drop-in replacements.

Q: What is the impact of different lifetime ratings?

A: Lifetime rating indicates hours of operation at 105°C before capacitance degradation reaches 80% of initial value. The original part specifies 5000 hours. Substitutes with equal or greater lifetime (5000, 6000, or 7000 hours) maintain or exceed reliability. Parts rated at 3000 hours have reduced operational life at elevated temperatures.

Q: Are all substitutes electrically identical to the UTS1H101MPD?

A: All listed substitutes maintain identical capacitance (100 µF), voltage rating (50 V), tolerance (±20%), polarization (polar), and operating temperature range (-40°C to 105°C). Electrical performance is equivalent across all substitutes for these core parameters.

Q: What is the difference between bulk and cut tape packaging?

A: Bulk packaging is supplied in standard quantities for general procurement. Cut tape (CT) packaging is pre-cut and taped for automated assembly equipment. Packaging does not affect electrical or mechanical performance; selection depends on assembly process requirements.

Q: Why are some Nichicon parts marked "Not For New Designs"?

A: This status indicates the manufacturer is phasing out the product line. While these parts remain available, they are not recommended for new product development. Active status parts from Panasonic are preferred for new designs requiring long-term supply assurance.

Q: Can I substitute a part with a taller height?

A: Height variation ranges from 9.00mm (original) to 13.00mm (some substitutes). Taller parts require verification of available PCB clearance above the component. If clearance is limited, select substitutes with heights closer to the original 9.00mm specification.
