UUR1C331MNL1GS Equivalent & Substitute Parts

Part Overview

The UUR1C331MNL1GS is a 330 µF, 16 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Nichicon. This component is rated for 2000 hours at 85°C and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers or higher-performance variants are necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Substitution Parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 16 V minimum (higher voltage ratings acceptable)
• Package Type: Radial, Can - SMD (mechanical compatibility)
• Case Dimensions: 0.315" Dia (8.00mm) with height tolerance ±0.019" (±0.50mm)
• Surface Mount Land Size: 0.327" L × 0.327" W (8.30mm × 8.30mm)
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Secondary Considerations:

• Lifetime rating at temperature (2000 Hrs @ 85°C or higher)
• Operating temperature range (-40°C minimum to 85°C minimum)
• Ripple current capability at standard frequencies

Substitutes are grouped into four categories: MFR Recommended (same manufacturer, improved performance), Upgrade (higher voltage rating), Direct (alternative manufacturer, equivalent specifications), and Similar (alternative manufacturer with minor dimensional or performance variations).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Specifications): Select EMVA160ARA331MHA0G (Chemi-Con, Active status) or EDK337M016A9MAA (KEMET, Active status). Both maintain identical electrical specifications and case dimensions as the original UUR1C331MNL1GS while offering active product status and full ROHS3 compliance.

For Enhanced Performance: Select UUX1C331MNL6GS (Nichicon, Active status) for improved thermal performance. This part maintains the same capacitance and voltage rating but extends lifetime to 2000 hours at 105°C and expands operating temperature range to -55°C ~ 105°C. Ripple current capability increases to 410 mA @ 120 Hz.

For Higher Voltage Margin: Select UUR1E331MNL6GS (Nichicon, 25 V rating) when circuit design permits higher voltage rating. This provides additional safety margin while maintaining 330 µF capacitance and 2000-hour lifetime at 85°C.

For Thermal Enhancement with Active Status: Select EMVE160ARA331MHA0G (Chemi-Con, Active status) for extended lifetime to 2000 hours at 105°C with expanded operating range to -40°C ~ 105°C. Case height is reduced to 0.394" (10.00mm), which may require PCB layout verification.

Avoid for New Designs: EEE-1CA331UP and EEE-1CA331P (Panasonic) are marked "Not For New Designs." EEE-1CA331UAP (Panasonic, Active) has reduced lifetime rating of 1000 hours at 85°C and larger case dimensions (0.394" Dia × 0.402" H), requiring PCB footprint verification.

Frequently Asked Questions (FAQ)

Q: Can I use a 25 V rated capacitor in place of the 16 V original? A: Yes. UUR1E331MNL6GS (25 V) is a valid upgrade substitute. Higher voltage ratings provide additional safety margin and are electrically compatible in 16 V circuits. Verify PCB layout accommodates the same case dimensions (0.315" Dia × 0.413" H).

Q: What is the difference between UUX1C331MNL6GS and the original UUR1C331MNL1GS? A: Both are 330 µF, 16 V capacitors with identical case size. UUX1C331MNL6GS is active production, rated for 2000 hours at 105°C (versus 85°C), and supports operating temperatures to 105°C. Ripple current capability increases from 270 mA to 410 mA @ 120 Hz.

Q: Are Chemi-Con and KEMET substitutes mechanically compatible? A: EMVA160ARA331MHA0G and EDK337M016A9MAA are mechanically compatible with identical capacitance, voltage, and land size (0.327" × 0.327"). EMVA160ARA331MHA0G has case height of 0.394" (10.00mm) versus original 0.413" (10.50mm). Verify PCB clearance before substitution.

Q: Why is EEE-1CA331UP not recommended for new designs? A: EEE-1CA331UP is marked "Not For New Designs" by Panasonic. While electrically compatible, it has larger case dimensions (0.394" Dia × 0.402" H) requiring PCB layout verification. Active alternatives with better lifecycle support are available.

Q: What is the impact of reduced lifetime rating in EEE-1CA331UAP? A: EEE-1CA331UAP has 1000-hour lifetime at 85°C versus 2000 hours in the original. This halves the expected service life under thermal stress. Use only in applications with lower thermal cycling or shorter service life requirements.

Q: Are all substitutes ROHS3 compliant? A: All listed substitutes maintain ROHS3 compliance and MSL rating of 1 (Unlimited). All are suitable for lead-free soldering processes and meet environmental regulations.

Q: Can I substitute AVE337M16F24T-F (Cornell Dubilier)? A: AVE337M16F24T-F is obsolete and not recommended. While electrically equivalent, it offers no lifecycle advantage over the original UUR1C331MNL1GS. Select active alternatives such as EMVA160ARA331MHA0G or EDK337M016A9MAA instead.
