• Lifetime: 1000 Hrs @ 105°C (exact match required)
• Polarization: Bi-Polar (exact match required)

Mechanical Parameters:

• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Case Diameter: 0.492" (12.50mm) (exact match required)
• Height: 0.866" (22.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can (exact match required)

The 35NXA330MEFC12.5X20 from Rubycon meets all specified electrical and mechanical parameters and qualifies as a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 35NXA330MEFC12.5X20 (Rubycon) is a direct parametric equivalent to the UEP1V331MHD. Both components meet identical electrical specifications, mechanical dimensions, and regulatory compliance requirements. The Rubycon part carries an active product status, ensuring continued availability for new applications, whereas the Nichicon UEP series is designated as not for new designs.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The ripple current specification of the Rubycon substitute (343 mA @ 120 Hz) is within acceptable tolerance of the original part (350 mA @ 120 Hz), confirming functional equivalence in thermal and electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the 35NXA330MEFC12.5X20 be used as a direct replacement for the UEP1V331MHD?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (35 V), tolerance (±20%), temperature range (-55°C ~ 105°C), lifetime rating (1000 Hrs @ 105°C), and mechanical dimensions (0.492" diameter, 0.866" height, 5.00mm lead spacing). They are functionally and mechanically interchangeable.

Q: Are there differences in ripple current handling between these parts?

A: The UEP1V331MHD is rated for 350 mA @ 120 Hz, while the 35NXA330MEFC12.5X20 is rated for 343 mA @ 120 Hz. This 7 mA difference is negligible for general-purpose applications and does not affect substitution eligibility.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the UEP1V331MHD and 35NXA330MEFC12.5X20 are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What is the primary reason for substitution?

A: The UEP1V331MHD is classified as not for new designs, indicating discontinued status. The Rubycon 35NXA330MEFC12.5X20 maintains active product status and identical specifications, making it the appropriate choice for ongoing applications and new designs.

Q: Are the through-hole mounting characteristics identical?

A: Yes. Both parts are through-hole mounted radial capacitors with identical lead spacing (5.00mm) and case dimensions (12.50mm diameter, 22.00mm height), ensuring identical PCB footprint compatibility.
