UVR1C101MDA Equivalent & Substitute Parts

Part Overview

The UVR1C101MDA is a 100 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C, suitable for general-purpose applications requiring stable capacitance and ripple current handling.

Substitute Part Grouping Explanation

Substitution for the UVR1C101MDA is determined by strict equivalence across the following critical parameters:

• Capacitance: 100 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Lead Spacing: 0.079" (2.00mm) (exact match required)
• Size / Dimension: 0.197" Dia (5.00mm) (exact match required)

Substitute parts are grouped into two categories: upgrade substitutes (improved compliance or performance characteristics) and similar substitutes (equivalent electrical and mechanical specifications from alternative manufacturers).

Engineering Selection Recommendations

UKW1C101MDD (Upgrade Substitute): This Nichicon part maintains identical electrical specifications and mechanical dimensions to the UVR1C101MDA while offering ROHS3 compliance. The product status remains obsolete, but this part provides improved regulatory alignment for new designs or production runs requiring RoHS certification.

ECA-1CM101, ECA-1CM101B, ECA-1CM101I (Similar Substitutes): These Panasonic parts are active products with ROHS3 compliance and identical core electrical parameters. All three variants meet the 100 µF, 16 V, ±20% tolerance specification. Selection among these three depends on lead spacing and packaging requirements:

• ECA-1CM101: Lead spacing 0.079" (2.00mm) — direct mechanical equivalent to UVR1C101MDA
• ECA-1CM101B: Lead spacing 0.197" (5.00mm) — requires PCB layout adjustment
• ECA-1CM101I: Lead spacing 0.098" (2.50mm) — intermediate spacing option

All Panasonic variants exhibit increased ripple current capability at 10 kHz (306 mA versus 240 mA), providing additional performance margin in high-frequency applications.

Frequently Asked Questions (FAQ)

Q: Can ECA-1CM101B be used as a direct replacement for UVR1C101MDA?

A: ECA-1CM101B is electrically equivalent but has a different lead spacing (0.197" versus 0.079"). PCB layout modification is required. If lead spacing cannot be changed, use ECA-1CM101 or ECA-1CM101I instead.

Q: What is the difference between the three Panasonic ECA-1CM101 variants?

A: The variants differ only in lead spacing and packaging format. ECA-1CM101 uses 0.079" spacing (matches UVR1C101MDA), ECA-1CM101B uses 0.197" spacing, and ECA-1CM101I uses 0.098" spacing. All are electrically identical.

Q: Is UKW1C101MDD suitable for new designs?

A: UKW1C101MDD is obsolete but offers ROHS3 compliance. For new designs, Panasonic ECA-1CM101 series parts are preferred as they carry active product status and ensure long-term availability.

Q: Do the substitute parts have the same height?

A: UVR1C101MDA and UKW1C101MDD both measure 0.433" (11.00mm) maximum seated height. Panasonic parts (ECA-1CM101, ECA-1CM101B, ECA-1CM101I) measure 0.472" (12.00mm). Verify PCB clearance before substitution.

Q: What is the impact of higher ripple current ratings in Panasonic parts?

A: Panasonic ECA-1CM101 series parts handle 306 mA at 10 kHz compared to 240 mA for UVR1C101MDA. This provides additional thermal margin and is not a limitation for substitution; it represents improved performance capability.
