Nichicon UCY2D331MHD Equivalent & Substitute Parts

Part Overview

The Nichicon UCY2D331MHD is a 330 µF, 200 V aluminum electrolytic capacitor in radial, can package rated for 12000 hours at 105°C. This component is classified as Active and suitable for general purpose applications. Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance) and mechanical compatibility (lead spacing, mounting type, package style). Alternative models may be required due to inventory availability, product lifecycle status, or specific application requirements such as automotive qualification or extended operational lifetime.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Matching Parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can (exact match required)

Secondary Compatibility Parameters:

• Lead Spacing: 0.295" (7.50mm) preferred for direct PCB compatibility
• Operating Temperature Range: -40°C ~ 105°C (exact match required)

Acceptable Variations:

• Lifetime @ 105°C: May vary (10000 Hrs, 12000 Hrs, or 8000 Hrs acceptable depending on application requirements)
• Physical Dimensions (diameter, height): Minor variations acceptable if lead spacing and mounting type remain compatible
• Manufacturer: Different manufacturers acceptable if all electrical and mechanical parameters match
• Product Status: Active preferred; Obsolete or Not For New Designs acceptable only if no Active alternatives available

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes (Active Status, Direct Compatibility):

• UCY2D331MHD6 (Nichicon): Active product with identical electrical specifications and matching lead spacing. Physical dimensions vary slightly (height 1.299" vs. 1.634"), but mounting compatibility is maintained. Suitable for space-constrained applications.

• UCS2D331MHD (Nichicon): Active product with matching lead spacing and electrical specifications. Lifetime rating reduced to 10000 hours at 105°C. Acceptable for applications where extended operational life is not critical.

• EKXJ201ELL331ML40S (Chemi-Con): Active product with AEC-Q200 automotive qualification. Identical electrical specifications and physical dimensions to the main part. Suitable for automotive applications requiring third-party manufacturer qualification.

Conditional Substitutes (Reduced Lifetime or Obsolete Status):

• UPW2D331MRD (Nichicon): Obsolete status. Lead spacing differs (0.394" vs. 0.295"), requiring PCB layout modification. Lifetime reduced to 8000 hours. Use only if no Active alternatives are available and PCB redesign is feasible.

• UVY2D331MHD (Nichicon): Not For New Designs status. Lifetime severely reduced to 2000 hours at 105°C. Use only for legacy system maintenance where original part specifications are mandatory.

Frequently Asked Questions (FAQ)

Q: Can UCY2D331MHD6 be used as a direct replacement for UCY2D331MHD?

A: Yes. Both parts share identical electrical specifications (330 µF, 200 V, ±20%, 12000 Hrs @ 105°C) and lead spacing (0.295" / 7.50mm). Physical height differs (1.299" vs. 1.634"), but this does not affect electrical compatibility. Verify available PCB clearance before substitution.

Q: What is the difference between UCS2D331MHD and UCY2D331MHD?

A: Both are Nichicon 330 µF, 200 V radial capacitors with matching lead spacing. The primary difference is lifetime rating: UCS2D331MHD is rated for 10000 hours at 105°C, while UCY2D331MHD is rated for 12000 hours. UCS2D331MHD has a larger diameter (0.709" vs. 0.630") and shorter height (1.457" vs. 1.634"). Select based on application lifetime requirements and available PCB space.

Q: Why is UPW2D331MRD listed as Obsolete?

A: UPW2D331MRD carries Obsolete product status, indicating it is no longer manufactured or supported. It is included for reference only when servicing legacy equipment. Lead spacing differs from the main part (0.394" vs. 0.295"), requiring PCB modification for installation. Active alternatives are recommended for new designs.

Q: Is EKXJ201ELL331ML40S suitable for automotive applications?

A: Yes. EKXJ201ELL331ML40S carries AEC-Q200 automotive qualification and is manufactured by Chemi-Con. It matches all electrical specifications of UCY2D331MHD (330 µF, 200 V, ±20%, 12000 Hrs @ 105°C) and shares identical physical dimensions. It is suitable for automotive-grade applications requiring third-party manufacturer qualification.

Q: Can UVY2D331MHD be used in new designs?

A: No. UVY2D331MHD carries Not For New Designs status and has a severely reduced lifetime rating of 2000 hours at 105°C compared to 12000 hours for UCY2D331MHD. It is suitable only for legacy system maintenance where original part specifications are mandatory. Active alternatives are required for new designs.

Q: What parameters must match exactly for substitution?

A: Capacitance (330 µF), voltage rating (200 V), tolerance (±20%), polarization (Polar), operating temperature range (-40°C ~ 105°C), mounting type (Through Hole), and package type (Radial, Can) must match exactly. Lead spacing (0.295" / 7.50mm) is preferred for direct PCB compatibility. Lifetime rating and physical dimensions may vary within acceptable limits.
