Substitute Part Grouping Explanation

Substitution for the UVZ2F3R3MPD is determined by the following criteria:

Primary Electrical Parameters:

Capacitance: 3.3 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: Equal to or greater than 315 V
Operating Temperature: -40°C ~ 105°C (minimum requirement)

Mechanical Parameters:

Lead Spacing: 0.197" (5.00mm)
Diameter: 0.394" (10.00mm)
Mounting Type: Through Hole
Package: Radial, Can

Acceptable Variations:

Voltage rating may be increased (350 V, 400 V) without affecting circuit compatibility
Height may vary within reasonable limits for through-hole mounting
Lifetime at temperature may differ between manufacturers
Ripple current specifications may vary by manufacturer

Substitute parts are grouped by voltage rating and manufacturer, with all candidates meeting the core electrical and mechanical requirements.

Engineering Selection Recommendations

Nichicon UVZ Series (UVZ2G3R3MPD, UVZ2V3R3MPD): These parts maintain identical mechanical dimensions and electrical characteristics to the UVZ2F3R3MPD with increased voltage ratings. Both are classified as not for new designs but remain available. Selection between 350 V and 400 V variants depends on circuit voltage requirements.

Chemi-Con KMG Series (EKMG351ELL3R3MJC5S, EKMG401ELL3R3MJC5S): These active-status parts offer equivalent capacitance and tolerance with higher voltage ratings. Height increases to 0.551" (14.00mm), which must be verified for PCB clearance. Lifetime is reduced to 1000 Hrs @ 105°C compared to the original 2000 Hrs specification. Both parts are ROHS3 compliant and suitable for new designs.

Cornell Dubilier Electronics SEK Series (SEK3R3M350ST, SEK3R3M400ST): These active-status parts provide 2000 Hrs @ 105°C lifetime matching the original specification. Height is 0.512" (13.00mm), intermediate between Nichicon and Chemi-Con variants. Both are ROHS3 compliant with specified ESR values and higher ripple current capability at 120 Hz.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute? A: Yes. A capacitor rated for 350 V or 400 V can replace the 315 V UVZ2F3R3MPD in the same circuit. Higher voltage ratings provide additional safety margin without affecting electrical performance at the original operating voltage.

Q: What is the impact of different heights on PCB compatibility? A: The UVZ2F3R3MPD has a maximum seated height of 0.492" (12.50mm). Chemi-Con KMG parts are 0.551" (14.00mm) and Cornell Dubilier SEK parts are 0.512" (13.00mm). PCB clearance must be verified before substitution. Nichicon UVZ variants maintain the original 0.492" height.

Q: Does reduced lifetime affect part selection? A: Chemi-Con KMG series parts specify 1000 Hrs @ 105°C versus 2000 Hrs for the original and Cornell Dubilier alternatives. Application duty cycle and thermal environment determine whether this reduction is acceptable. For continuous high-temperature operation, 2000 Hrs lifetime is preferred.

Q: Are all substitute parts through-hole mounted? A: Yes. All listed substitutes are through-hole radial, can package components with 0.197" (5.00mm) lead spacing, maintaining mechanical compatibility with the original UVZ2F3R3MPD footprint.

Q: Which substitutes are suitable for new designs? A: Chemi-Con EKMG351ELL3R3MJC5S, EKMG401ELL3R3MJC5S and Cornell Dubilier SEK3R3M350ST, SEK3R3M400ST are classified as active products. Nichicon UVZ variants are not for new designs.
