Lead Spacing: 0.197" (5.00 mm) (exact match required for PCB compatibility)
Case Diameter: 0.492" (12.50 mm) (exact match required for mechanical fit)
Height: 1.299" (33.00 mm) (exact match required for clearance)
Mounting Type: Through Hole (exact match required)

Engineering Selection Recommendations

Direct Mechanical Substitutes (Identical PCB Footprint):

UCY2W330MHD and UPTW6330MHD are direct mechanical substitutes for UPT2G330MHD. Both maintain the 0.197" (5.00 mm) lead spacing and 0.492" (12.50 mm) case diameter, requiring no PCB layout modifications. UCY2W330MHD provides enhanced performance with 450 V rating and 12000-hour lifetime. UPTW6330MHD offers 420 V rating with equivalent 5000-hour lifetime. Both are Active status products with ROHS3 compliance.

Alternative Mechanical Configurations (PCB Layout Modification Required):

Panasonic EEU-ED2G330S and EEU-EE2G330S provide extended lifetime (10000 hours) with 400 V rating but require different lead spacing (0.295" vs. 0.197") and case diameter (0.630" vs. 0.492"). These substitutes demand PCB redesign and are suitable only when mechanical constraints permit. Both are Active status with ROHS3 compliance.

ECA-2GHG330B is rated for automotive applications (AEC-Q200) with 400 V and 2000-hour lifetime. This part requires PCB modification due to different mechanical dimensions and reduced lifetime rating.

UCA2G330MHD6 is classified as Obsolete and should not be selected for new designs despite 12000-hour lifetime rating.

Frequently Asked Questions (FAQ)

Q: Can UCY2W330MHD replace UPT2G330MHD without PCB modification?

A: Yes. UCY2W330MHD maintains identical lead spacing (0.197" / 5.00 mm), case diameter (0.492" / 12.50 mm), and height (1.299" / 33.00 mm). Direct substitution on existing PCBs is possible. The higher voltage rating (450 V vs. 400 V) and extended lifetime (12000 Hrs vs. 5000 Hrs) represent performance enhancements.

Q: What is the difference between Nichicon UPT and UCY series?

A: Both series are Nichicon aluminum electrolytic capacitors with identical mechanical envelopes. The UCY series provides higher voltage rating (450 V) and extended lifetime (12000 hours at 105°C) compared to the UPT series (400 V, 5000 hours). The UCY series is suitable for applications requiring enhanced reliability and voltage margin.

Q: Can Panasonic EEU-ED2G330S or EEU-EE2G330S be used as direct substitutes?

A: No. These Panasonic parts require PCB modification. Lead spacing differs (0.295" vs. 0.197") and case diameter differs (0.630" vs. 0.492"). Mechanical redesign is necessary. However, both offer extended lifetime (10000 hours) and higher ripple current capability, making them suitable for redesigned applications.

Q: Why is UCA2G330MHD6 listed as Obsolete?

A: UCA2G330MHD6 is classified as Obsolete product status. New designs should not incorporate obsolete components. Although this part offers 12000-hour lifetime and different mechanical dimensions, Active alternatives such as UCY2W330MHD provide equivalent or superior performance with ongoing manufacturer support.

Q: What is the significance of lead spacing in capacitor substitution?

A: Lead spacing determines PCB hole pattern compatibility. UPT2G330MHD uses 0.197" (5.00 mm) spacing. Substitutes with identical spacing (UCY2W330MHD, UPTW6330MHD) mount directly without PCB modification. Substitutes with 0.295" (7.50 mm) spacing require PCB redesign and cannot be used as drop-in replacements.

Q: Are all listed substitutes ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance, matching the original UPT2G330MHD specification.
