UWS1C331MCL1GS Equivalent & Substitute Parts

Part Overview

The UWS1C331MCL1GS is a 330 µF, 16 V aluminum electrolytic capacitor manufactured by Nichicon in the UWS series. This surface mount component is rated for 2000 hours at 85°C and is designed for high temperature reflow applications. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications requiring 330 µF capacitance at 16 V with compatible mechanical and electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Case Diameter: 0.315" (8.00mm) or compatible footprint
• Mounting Type: Surface Mount
• Package Type: Radial, Can - SMD
• Moisture Sensitivity Level: MSL 1

Parts are grouped into three categories based on substitution relationship:

Direct Equivalent: UUR1C331MNL1GS (Nichicon UUR series) — identical electrical specifications and mechanical compatibility with same case size and height.

Direct Substitute: EMVA160ARA331MHA0G and EMVE160ARA331MHA0G (Chemi-Con Alchip series) — meet all core electrical parameters with identical case dimensions. EMVE160ARA331MHA0G offers extended temperature operation to 105°C.

Similar Substitute: AVE337M16F24T-F (Cornell Dubilier), EEE-1CA331AP, EEE-1CA331P, EEE-1CA331UAP, and EEE-1CA331UP (Panasonic) — meet electrical specifications with minor mechanical variations in case diameter or height that remain within acceptable PCB footprint tolerances.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): UUR1C331MNL1GS is the primary equivalent from Nichicon. Both parts share identical electrical specifications and case diameter. The height difference of 0.5mm (10.50mm vs 10.00mm) is within standard PCB clearance tolerances for surface mount applications.

For Active Product Status: EMVA160ARA331MHA0G and EMVE160ARA331MHA0G from Chemi-Con are active products meeting all core electrical parameters. EMVE160ARA331MHA0G provides extended temperature operation to 105°C, suitable for applications requiring higher thermal margins. Both are ROHS3 compliant.

For Automotive Applications: EEE-1CA331UAP and EEE-1CA331UP from Panasonic carry AEC-Q200 ratings. EEE-1CA331UAP is currently active; however, it specifies 1000 hours lifetime at 85°C versus the 2000-hour specification of the original part. EEE-1CA331UP maintains 2000-hour lifetime but is marked "Not For New Designs."

For Legacy System Maintenance: AVE337M16F24T-F from Cornell Dubilier meets electrical specifications and maintains identical case dimensions. This part is obsolete but available in inventory.

Footprint Consideration: Panasonic EEE-1CA series parts (EEE-1CA331AP, EEE-1CA331P) feature a 10.00mm case diameter versus the 8.00mm diameter of the original part. PCB land pattern compatibility must be verified before selection.

Frequently Asked Questions (FAQ)

Q: Can UUR1C331MNL1GS directly replace UWS1C331MCL1GS?

A: Yes. Both parts are Nichicon products with identical capacitance (330 µF), voltage rating (16 V), tolerance (±20%), and lifetime specification (2000 Hrs @ 85°C). The height difference of 0.5mm falls within standard surface mount assembly tolerances and does not affect electrical performance.

Q: What is the difference between EMVA160ARA331MHA0G and EMVE160ARA331MHA0G?

A: Both are Chemi-Con Alchip series parts with identical electrical specifications and case dimensions. EMVE160ARA331MHA0G extends the operating temperature range to 105°C and specifies 2000-hour lifetime at 105°C, compared to EMVA160ARA331MHA0G which operates to 85°C. Select EMVE for applications requiring higher temperature performance.

Q: Why do Panasonic EEE-1CA331AP and EEE-1CA331P have a larger case diameter?

A: These parts feature a 10.00mm case diameter compared to the 8.00mm diameter of the original UWS1C331MCL1GS. The larger case accommodates higher ripple current capability (380 mA @ 120 Hz vs 270 mA @ 120 Hz). PCB footprint compatibility must be verified; these parts may not fit existing 8.00mm diameter land patterns without layout modification.

Q: Is EEE-1CA331UAP suitable for applications requiring 2000-hour lifetime?

A: No. EEE-1CA331UAP specifies 1000 hours at 85°C, which is half the 2000-hour lifetime of the original part. For equivalent lifetime performance, select EEE-1CA331UP, which maintains the 2000-hour specification, though it is marked "Not For New Designs."

Q: Which substitute parts are currently in active production?

A: EMVA160ARA331MHA0G, EMVE160ARA331MHA0G, and EEE-1CA331UAP are active products. All other substitutes are either obsolete or marked "Not For New Designs." For new designs, Chemi-Con Alchip series or Panasonic EEE-1CA331UAP are recommended.

Q: Are all substitute parts RoHS compliant?

A: EMVA160ARA331MHA0G, EMVE160ARA331MHA0G, AVE337M16F24T-F, and EEE-1CA331UAP are ROHS3 compliant. EEE-1CA331UP, EEE-1CA331AP, and EEE-1CA331P are RoHS compliant. All parts are REACH unaffected or compliant.
