UMA0J100MCD2 Equivalent & Substitute Parts

Part Overview

The UMA0J100MCD2 is a 10 µF, 6.3 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C, serving general-purpose applications requiring stable capacitance and low equivalent series resistance in compact form factors.

Substitute Part Grouping Explanation

Substitution of the UMA0J100MCD2 is determined by the following critical parameters: capacitance value (10 µF), tolerance (±20%), polarization (polar), package type (radial, can), and mounting configuration (through hole). The voltage rating may be increased in substitute parts without functional degradation, as higher voltage-rated capacitors operate safely in lower voltage applications. Lead spacing, physical dimensions, and height must remain compatible with the original PCB layout to ensure mechanical fit and electrical performance.

The UVR1C100MDD qualifies as a direct substitute based on matching capacitance, tolerance, polarization, package type, and mounting method. Although the UVR1C100MDD features a higher voltage rating (16 V versus 6.3 V), increased lead spacing (0.079" versus 0.039"), larger physical dimensions (0.197" diameter versus 0.118"), and greater height (0.492" versus 0.236"), these differences represent design trade-offs that may require PCB layout verification before implementation.

Parameter Comparison

Engineering Selection Recommendations

Both the UMA0J100MCD2 and UVR1C100MDD are classified as obsolete products. Selection between these components should be based on PCB layout constraints and available inventory. The UVR1C100MDD provides higher voltage margin (16 V versus 6.3 V) and increased ripple current capacity, which may offer improved performance stability in applications subject to voltage transients or elevated ripple conditions. However, the UVR1C100MDD requires larger PCB footprint accommodation due to increased lead spacing and physical dimensions.

Both parts maintain ROHS3 compliance and identical thermal performance specifications (2000 hours at 85°C). Mechanical compatibility with existing PCB layouts must be verified before substitution, particularly regarding lead spacing and component height clearance.

Frequently Asked Questions (FAQ)

Q: Can the UVR1C100MDD directly replace the UMA0J100MCD2 without circuit modification?

A: Electrical substitution is valid due to matching capacitance, tolerance, and thermal ratings. However, mechanical compatibility requires verification. The UVR1C100MDD has different lead spacing (0.079" versus 0.039") and larger physical dimensions (0.197" diameter, 0.492" height versus 0.118" diameter, 0.236" height). PCB layout modification may be necessary.

Q: What is the significance of the higher voltage rating on the UVR1C100MDD?

A: The 16 V rating on the UVR1C100MDD provides additional voltage margin compared to the 6.3 V rating of the UMA0J100MCD2. In applications operating at or below 6.3 V, the higher-rated substitute operates safely with no functional degradation. This characteristic is standard in capacitor substitution practice.

Q: Are both parts suitable for the same applications?

A: Both parts are rated for general-purpose applications and share identical operating temperature ranges (-40°C to 85°C) and thermal lifetime specifications (2000 hours at 85°C). Application suitability depends on circuit voltage requirements, available PCB space, and ripple current demands.

Q: What compliance certifications apply to both parts?

A: Both the UMA0J100MCD2 and UVR1C100MDD are ROHS3 compliant and REACH unaffected. Both carry ECCN classification EAR99 and HTSUS code 8532.22.0020.

Q: How do ripple current specifications differ between these parts?

A: The UVR1C100MDD supports higher ripple current capacity: 50 mA at 120 Hz and 100 mA at 10 kHz, compared to 15 mA at 120 Hz and 22.5 mA at 10 kHz for the UMA0J100MCD2. This increased capacity may benefit applications with elevated AC ripple conditions.
