Nichicon UVR1C100MDA Equivalent & Substitute Parts

Part Overview

The Nichicon UVR1C100MDA is a 10 µF, 16 V aluminum electrolytic capacitor in radial, can package with 2000 hours lifetime at 85°C. This part is classified as obsolete. Due to its obsolete status and limited remaining inventory (959 pcs), identifying equivalent and substitute parts is necessary for design continuity and procurement planning. Substitute parts maintain the same capacitance and tolerance while offering improved compliance status, extended temperature ranges, or higher voltage ratings for enhanced circuit reliability.

Substitute Part Grouping Explanation

Substitution for the UVR1C100MDA is determined by the following critical parameters:

Primary Substitution Criteria:

Capacitance: 10 µF (exact match required)
Tolerance: ±20% (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)
Lead Spacing: 0.079" (2.00 mm) (exact match required)
Size / Dimension: 0.197" Dia (5.00 mm) (exact match required)

Secondary Substitution Criteria (allows variation):

Voltage - Rated: 16 V or higher (higher voltage provides design margin)
Height - Seated: 0.433" (11.00 mm) or 0.492" (12.50 mm) (minor variation acceptable for through-hole mounting)
Lifetime @ Temperature: 2000 Hrs @ 85°C or extended (2000 Hrs @ 105°C acceptable)
Operating Temperature Range: -40°C ~ 85°C or extended (e.g., -55°C ~ 105°C acceptable)
RoHS Status: Upgrade to ROHS3 Compliant preferred

Substitute parts are grouped into three categories:

Direct Substitutes (Same Voltage Rating): Parts maintaining 16 V rating with identical electrical and mechanical specifications, offering improved compliance or packaging options.

Upgrade Substitutes (Higher Voltage Rating): Parts with 25 V, 35 V, 50 V, or 63 V ratings. These provide voltage margin and are electrically compatible in 16 V circuits. Higher voltage ratings enable use in circuits with transient overvoltage conditions.

Similar Substitutes (Same Voltage, Different Series): Parts from alternative Nichicon series with identical 63 V rating and mechanical compatibility, offering alternative sourcing options.

Engineering Selection Recommendations

Direct Replacement (Same Voltage): UVR1C100MDD is the primary direct substitute. It maintains identical electrical specifications (10 µF, 16 V, ±20%, 2000 Hrs @ 85°C) and mechanical compatibility. The only differences are ROHS3 compliance and a marginal height increase (0.492" vs 0.433"), which is acceptable for through-hole mounting. Inventory availability (1049 pcs) supports immediate procurement.

Voltage Upgrade Path (Higher Voltage Rating): For applications requiring enhanced reliability or transient overvoltage protection, upgrade substitutes are available:

UPW1E100MDD (25 V): Offers extended operating temperature range (-55°C ~ 105°C) and improved lifetime rating (2000 Hrs @ 105°C). Suitable for general-purpose applications requiring wider temperature operation. Highest inventory (31813 pcs).
UPW1V100MDD (35 V): Provides 35 V rating with extended temperature range (-55°C ~ 105°C). Inventory: 14628 pcs.
UKW1H100MDD or UFW1H100MDD (50 V): Both offer 50 V rating with ROHS3 compliance. UKW1H100MDD maintains original height (0.433"), while UFW1H100MDD has increased height (0.492"). Inventory: 6937 pcs and 60300 pcs respectively.
UVR1J100MDD, UFW1J100MDD, or UKW1J100MDD (63 V): Highest voltage rating (63 V) with ROHS3 compliance. UVR1J100MDD and UKW1J100MDD maintain 0.433" height; UFW1J100MDD has 0.492" height. Inventory: 23354 pcs, 17707 pcs, and 3947 pcs respectively.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute for the UVR1C100MDA?

A: Yes. A capacitor with higher voltage rating (25 V, 35 V, 50 V, or 63 V) is electrically compatible in a 16 V circuit. Higher voltage ratings provide design margin for transient overvoltage conditions and do not degrade circuit performance. The capacitance (10 µF) and tolerance (±20%) remain identical.

Q: What is the difference between UVR1C100MDD and UVR1C100MDA?

A: Both parts are 10 µF, 16 V, ±20% aluminum electrolytic capacitors with identical electrical specifications. The primary differences are: UVR1C100MDD is ROHS3 compliant (UVR1C100MDA is not), and UVR1C100MDD has a maximum seated height of 0.492" compared to 0.433" for UVR1C100MDA. This height difference is acceptable for through-hole mounting applications.

Q: Are there mechanical compatibility concerns when substituting with higher voltage parts?

A: No. All substitute parts maintain identical lead spacing (0.079" / 2.00 mm), diameter (0.197" / 5.00 mm), and mounting type (through-hole radial). Height variations (0.433" or 0.492") do not affect through-hole mounting compatibility. Verify PCB layout clearance if height is a constraint.

Q: Which substitute offers the best inventory availability?

A: UFW1H100MDD (50 V) has the highest inventory at 60300 pcs. For 16 V equivalent rating, UVR1C100MDD has 1049 pcs available.

Q: What does ROHS3 compliance mean for this capacitor?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, mercury, cadmium, hexavalent chromium, and specific brominated flame retardants. All substitute parts listed are ROHS3 compliant, while the original UVR1C100MDA is not.

Q: Can I substitute a Vishay Sprague 515D part for the Nichicon UVR1C100MDA?

A: Yes. The 515D106M025JA6AE3 (25 V) and 515D106M035JA6AE3 (35 V) are mechanically and electrically compatible. Both maintain 10 µF capacitance, ±20% tolerance, identical lead spacing, diameter, and height. Both are ROHS3 compliant.

Q: What is the impact of extended operating temperature range on part selection?

A: UPW series parts (UPW1E100MDD and UPW1V100MDD) offer extended operating range (-55°C ~ 105°C) compared to the original (-40°C ~ 85°C). These parts also have improved lifetime rating (2000 Hrs @ 105°C). Select these if your application requires operation at temperatures below -40°C or above 85°C.

Q: Are ripple current ratings affected by voltage rating changes?

A: Yes. Higher voltage-rated parts generally have higher ripple current ratings. For example, UVR1C100MDA (16 V) has 50 mA @ 120 Hz, while UVR1J100MDD (63 V) has 65 mA @ 120 Hz. Verify ripple current specifications match your circuit requirements.
