Substitute Part Grouping Explanation

Substitution for the UPW1J331MHH is determined by strict equivalence across the following critical parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can (exact match required)
• Lead Spacing: 0.197" (5.00 mm) (exact match required)
• Physical Dimensions: 0.492" Dia × 0.787" Height (exact match required)
• Mounting Type: Through Hole (exact match required)

The substitute part UPW1J331MHD meets all these criteria and is therefore a direct functional equivalent. Both parts share identical electrical specifications, thermal ratings, and mechanical compatibility, ensuring seamless integration into existing PCB designs and assemblies.

Parameter Comparison

Engineering Selection Recommendations

The UPW1J331MHD is the direct substitute for the UPW1J331MHH. Both parts are manufactured by Nichicon and belong to the same UPW series. The primary distinction is product status and regulatory compliance:

The UPW1J331MHH is classified as Obsolete and carries RoHS non-compliant status. The UPW1J331MHD is classified as Not For New Designs but achieves ROHS3 compliance, making it suitable for applications requiring regulatory adherence to modern environmental standards.

For legacy system maintenance or repair where the original UPW1J331MHH is unavailable, the UPW1J331MHD provides electrical and mechanical equivalence with improved compliance posture. All electrical parameters, thermal ratings, and physical dimensions are identical, ensuring direct PCB compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can UPW1J331MHD be used as a direct replacement for UPW1J331MHH?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (63 V), tolerance (±20%), thermal characteristics (7000 Hrs @ 105°C), physical dimensions (0.492" Dia × 0.787" Height), lead spacing (5.00 mm), and electrical performance (ripple current, impedance). No circuit modification or PCB redesign is required.

Q: What is the difference between UPW1J331MHH and UPW1J331MHD?

A: The primary differences are product status and RoHS compliance. UPW1J331MHH is Obsolete and RoHS non-compliant. UPW1J331MHD is Not For New Designs but ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or mounting differences?

A: No. Both parts use identical Through Hole radial can packaging with 0.197" (5.00 mm) lead spacing and matching physical dimensions. Direct PCB footprint compatibility is confirmed.

Q: What does "Not For New Designs" mean for UPW1J331MHD?

A: This designation indicates the part is available for existing production and support of legacy systems but is not recommended for incorporation into new product designs. For applications requiring long-term supply assurance, alternative modern capacitor families should be evaluated.

Q: Is RoHS3 compliance important for my application?

A: RoHS3 compliance is mandatory for products sold in regulated markets (EU, China, and others). If your application or end market requires RoHS compliance, UPW1J331MHD is the appropriate choice over the non-compliant UPW1J331MHH.
