Engineering Selection Recommendations

For Existing Designs (Maintenance and Repair):

UVZ2G3R3MPD and UVZ2V3R3MPD are direct Nichicon UVZ series substitutes with identical mechanical and electrical characteristics except for voltage rating. Both parts are ROHS3 compliant and provide higher voltage ratings (400 V and 350 V respectively) than the original 315 V specification, ensuring backward compatibility. These parts are classified as "Not For New Designs" but remain suitable for replacement in existing applications.

For New Designs:

SEK3R3M350ST and SEK3R3M400ST from Cornell Dubilier Electronics are active product alternatives with full ROHS3 compliance. Both parts meet all electrical and mechanical requirements. The SEK3R3M350ST matches the original 315 V voltage class at 350 V, while SEK3R3M400ST provides 400 V rating. Note that SEK series parts have a maximum seated height of 0.512" (13.00mm) compared to 0.492" (12.50mm) for the UVZ series, requiring PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can UVZ2G3R3MPD or UVZ2V3R3MPD be used as direct replacements for UVZ2F3R3MPH?

A: Yes. Both parts share identical capacitance (3.3 µF), tolerance (±20%), lifetime (2000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), lead spacing (5.00mm), and physical dimensions (0.394" Dia, 0.492" height). The higher voltage ratings (400 V and 350 V) are compatible with the original 315 V application.

Q: What is the difference between Nichicon UVZ series and Cornell Dubilier SEK series substitutes?

A: Both series meet the core electrical specifications. The primary difference is the maximum seated height: UVZ series is 0.492" (12.50mm), while SEK series is 0.512" (13.00mm). This 0.020" difference must be verified against PCB clearance requirements before selection.

Q: Are all substitute parts RoHS compliant?

A: UVZ2G3R3MPD and UVZ2V3R3MPD are ROHS3 compliant. SEK3R3M350ST and SEK3R3M400ST are ROHS3 compliant. The original UVZ2F3R3MPH is RoHS non-compliant.

Q: Which substitute part is recommended for new designs?

A: SEK3R3M350ST or SEK3R3M400ST are recommended for new designs as both are classified as active products with full ROHS3 compliance. Selection between 350 V and 400 V ratings depends on circuit voltage requirements.

Q: Can I use a 400 V rated capacitor in place of a 315 V rated capacitor?

A: Yes. A higher voltage rating capacitor is electrically compatible with lower voltage applications. The capacitor will operate safely within the lower voltage environment.
