UCP2G330MPD Equivalent & Substitute Parts

Part Overview

The UCP2G330MPD is a 33 µF, 400 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 10,000 hours at 105°C and is designed for general-purpose applications requiring reliable energy storage and filtering in power supply circuits. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation, ensuring continued availability and regulatory compliance for new designs and legacy system maintenance.

Substitute parts become necessary when the original component reaches end-of-life inventory levels, when design requirements allow for higher voltage ratings, or when system specifications permit upgraded performance characteristics while maintaining mechanical and electrical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the UCP2G330MPD is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match Exactly):

Capacitance: 33 µF
Tolerance: ±20%
Polarization: Polar
Lead Spacing: 0.197" (5.00 mm)
Case Diameter: 0.394" (10.00 mm)
Height (Seated Max): 1.319" (34.60 mm)
Mounting Type: Through Hole
Package Type: Radial, Can
Operating Temperature Range: -25°C to 105°C
Lifetime @ Temperature: 10,000 Hrs @ 105°C

Allowable Variation Parameters:

Voltage Rating: May be equal to or higher than 400 V (uprating permitted)
Ripple Current: May vary within manufacturer specifications for the rated voltage

The UCPW6330MPD qualifies as a direct substitute because it maintains all critical parameters while providing a higher voltage rating of 420 V, which is an acceptable uprating for applications designed for 400 V operation.

Engineering Selection Recommendations

The UCPW6330MPD serves as a qualified substitute for the UCP2G330MPD in applications where the circuit design permits voltage uprating from 400 V to 420 V. Both components maintain identical mechanical footprints, identical capacitance and tolerance specifications, and equivalent thermal performance characteristics. Both parts carry Active product status with full ROHS3 compliance and REACH unaffected designation, ensuring regulatory compliance and supply chain continuity.

Selection between these parts should be based on circuit voltage margin requirements and application-specific ripple current demands. The 420 V rating of the UCPW6330MPD provides additional voltage headroom for systems operating near the 400 V nominal specification. The slight reduction in ripple current specifications (320 mA at 120 Hz versus 330 mA, and 480 mA at 100 kHz versus 495 mA) must be evaluated against actual circuit ripple current requirements to ensure adequate performance margin.

Frequently Asked Questions (FAQ)

Q: Can the UCPW6330MPD replace the UCP2G330MPD in a 400 V circuit?

A: Yes. The UCPW6330MPD is rated for 420 V, which exceeds the 400 V requirement. Higher voltage ratings provide additional safety margin and are electrically compatible with lower-voltage circuit designs.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components share identical lead spacing (0.197" / 5.00 mm), case diameter (0.394" / 10.00 mm), and seated height (1.319" / 34.60 mm). PCB layout and mechanical mounting require no modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both UCP2G330MPD and UCPW6330MPD are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the difference in ripple current specifications?

A: The UCP2G330MPD is rated for 330 mA at 120 Hz and 495 mA at 100 kHz. The UCPW6330MPD is rated for 320 mA at 120 Hz and 480 mA at 100 kHz. Applications must verify that actual circuit ripple current does not exceed the substitute part's specifications.

Q: Are both parts available in the same packaging format?

A: Yes. Both components are supplied in radial, can package format for through-hole mounting. No PCB assembly process modifications are required.

Q: What is the thermal performance equivalence?

A: Both parts are rated for 10,000 hours at 105°C with identical operating temperature range of -25°C to 105°C, ensuring equivalent reliability and lifespan in thermal stress conditions.
