Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UCY2C331MHD6 is determined by the following critical parameters:

• Electrical Parameters: Capacitance (330 µF), voltage rating (160 V), and tolerance (±20%) must match exactly
• Mechanical Parameters: Lead spacing (7.50mm) and through-hole mounting type must be compatible with the PCB layout
• Thermal Parameters: Operating temperature range (-40°C ~ 105°C) must be maintained
• Compliance: RoHS3 compliance is required for equivalent substitution

Substitute parts are grouped into three categories:

1. Direct Substitutes (Packaging Variant): Same manufacturer (Nichicon), same series (UCY), identical electrical and mechanical specifications, differing only in packaging format (Cut Tape vs. Bulk)

2. Similar Substitutes (Same Manufacturer, Different Series): Nichicon parts from different series (UCY vs. UVZ) with matching core electrical parameters but variations in physical dimensions or thermal ratings

3. Cross-Manufacturer Substitutes: Parts from Chemi-Con (EKXJ and EKXG series) meeting identical electrical specifications with equivalent mechanical compatibility

Parameter Comparison

Engineering Selection Recommendations

Preferred Direct Substitute: UCY2C331MHD6TN is the optimal choice when packaging format flexibility is acceptable. This part maintains identical electrical and mechanical specifications to the primary part while offering Cut Tape packaging, which may provide cost or supply chain advantages. Both parts are Active status and ROHS3 compliant.

Alternative Within Manufacturer: UCY2C331MHD from Nichicon's UCY series provides equivalent electrical performance and thermal rating (12000 Hrs @ 105°C) with identical lead spacing. Physical dimensions differ (16.00mm diameter, 33.00mm height vs. 18.00mm diameter, 26.50mm height), requiring PCB layout verification before substitution.

Cross-Manufacturer Equivalent: EKXJ161ELL331MM25S from Chemi-Con provides identical electrical specifications, thermal rating (12000 Hrs @ 105°C), and physical dimensions to the primary part. This part carries AEC-Q200 automotive qualification and is suitable for applications requiring cross-manufacturer compatibility.

Not Recommended for New Designs: UVZ2C331MHD is marked "Not For New Designs" and features reduced thermal rating (2000 Hrs @ 105°C). This part should only be considered for legacy system maintenance or repair applications where the original specification is documented.

Secondary Alternative: EKXG161ELL331MMN3S from Chemi-Con meets electrical requirements with slightly reduced thermal rating (10000 Hrs @ 105°C vs. 12000 Hrs). Physical height differs (31.50mm vs. 26.50mm), requiring PCB clearance verification.

Frequently Asked Questions (FAQ)

Q: Can UCY2C331MHD6TN be used as a direct replacement for UCY2C331MHD6?

A: Yes. Both parts are identical in electrical specifications, thermal rating, and physical dimensions. The only difference is packaging format (Cut Tape vs. Bulk). PCB assembly compatibility depends on your manufacturing process requirements.

Q: What is the key difference between UCY2C331MHD6 and UCY2C331MHD?

A: Both parts share identical capacitance (330 µF), voltage rating (160 V), and thermal rating (12000 Hrs @ 105°C). Physical dimensions differ: UCY2C331MHD6 measures 18.00mm diameter × 26.50mm height, while UCY2C331MHD measures 16.00mm diameter × 33.00mm height. Lead spacing remains 7.50mm for both. Verify PCB layout compatibility before substitution.

Q: Why is UVZ2C331MHD marked "Not For New Designs"?

A: The UVZ2C331MHD has a reduced thermal lifetime rating of 2000 Hrs @ 105°C compared to 12000 Hrs for the UCY series. This part is retained for legacy system support only and should not be used in new product designs.

Q: Can Chemi-Con parts replace Nichicon parts directly?

A: EKXJ161ELL331MM25S provides full electrical and mechanical equivalence to UCY2C331MHD6 with identical physical dimensions and thermal rating. EKXG161ELL331MMN3S has slightly reduced thermal rating (10000 Hrs vs. 12000 Hrs) and different height (31.50mm vs. 26.50mm). Verify application thermal requirements and PCB clearance before substitution.

Q: What parameters must match for a valid substitution?

A: Capacitance (330 µF), voltage rating (160 V), tolerance (±20%), lead spacing (7.50mm), and operating temperature range (-40°C ~ 105°C) must match exactly. Thermal lifetime rating and physical dimensions should be verified against application requirements and PCB layout constraints.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, ensuring compatibility with RoHS3 regulated applications and supply chains.
