Equivalent & Substitute Parts for UTT1C100MDD

Part Overview

The UTT1C100MDD is a 10 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 5000 hours at 105°C and is designed for general-purpose applications. The product status is obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the UTT1C100MDD is determined by the following criteria:

• Capacitance Match: 10 µF (exact match required)
• Voltage Rating: Must be equal to or greater than 16 V
• Tolerance: ±20% (standard for aluminum electrolytic capacitors)
• Mounting Type: Through Hole radial configuration
• Package Type: Radial, Can
• Compliance: ROHS3 Compliant

The substitute parts identified maintain the same capacitance value and tolerance while offering equal or higher voltage ratings and comparable thermal performance. Physical dimensions and lead spacing may vary within acceptable PCB layout tolerances.

Parameter Comparison

Engineering Selection Recommendations

UHE1H100MDD provides a direct functional equivalent with identical capacitance, tolerance, and thermal lifetime rating. The 50 V voltage rating exceeds the 16 V requirement, offering additional design margin. However, physical dimensions are larger, requiring PCB layout verification. Product status is obsolete.

RNS1E100MDS1 is an active product offering 10 µF capacitance with 25 V voltage rating and polymer construction. The extended operating temperature range (-55°C to 105°C) provides broader environmental coverage. Thermal lifetime is reduced to 2000 hours at 105°C. Physical dimensions are larger than the original part. This option is recommended for new designs requiring active product availability.

Both substitute parts are ROHS3 compliant and manufactured by Nichicon, maintaining supply chain consistency.

Frequently Asked Questions (FAQ)

Q: Can UHE1H100MDD be used as a direct replacement for UTT1C100MDD?

A: UHE1H100MDD matches the capacitance (10 µF), tolerance (±20%), thermal rating (5000 Hrs @ 105°C), and operating temperature range (-40°C ~ 105°C). The higher voltage rating (50 V vs. 16 V) is acceptable for applications designed for 16 V. Physical dimensions differ; PCB layout must accommodate the larger can size (0.197" diameter vs. 0.157" diameter) and increased height (0.492" vs. 0.276").

Q: What is the difference between UHE1H100MDD and RNS1E100MDS1?

A: UHE1H100MDD is a standard aluminum electrolytic capacitor with 5000-hour lifetime at 105°C. RNS1E100MDS1 is an aluminum-polymer capacitor with 2000-hour lifetime at 105°C but lower ESR (63 mOhm) and higher ripple current capability. RNS1E100MDS1 is an active product; UHE1H100MDD is obsolete.

Q: Are there physical compatibility concerns when substituting these parts?

A: Yes. Lead spacing and physical dimensions differ among all three parts. UTT1C100MDD has 0.059" lead spacing; UHE1H100MDD has 0.079" spacing; RNS1E100MDS1 has 0.098" spacing. Height also varies significantly. PCB footprint and component placement must be evaluated before substitution.

Q: Which substitute is recommended for new designs?

A: RNS1E100MDS1 is the recommended choice for new designs because it is an active product with current manufacturing support. UHE1H100MDD and UTT1C100MDD are both obsolete and subject to availability constraints.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.
