Substitute Part Grouping Explanation

Substitution for the UVR2V3R3MPD is determined by strict equivalence in the following parameters:

Capacitance: 3.3 µF (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)
Lead Spacing: 0.197" (5.00mm) (exact match required)
Size / Dimension: 0.394" Dia (10.00mm) (exact match required)
Height - Seated (Max): 0.551" (14.00mm) (exact match required)

Voltage rating may be equal to or higher than 350 V. Operating temperature range and lifetime specifications must meet or exceed the original part requirements. All substitute parts must maintain ROHS3 compliance and REACH unaffected status.

Engineering Selection Recommendations

For direct pin-compatible replacement with identical mechanical footprint, UVR2G3R3MPD is the primary upgrade option. This Nichicon part maintains all mechanical dimensions and lead spacing while providing increased voltage rating (400 V vs. 350 V), offering improved design margin. However, UVR2G3R3MPD retains Not For New Designs status.

For new designs or applications requiring active product status, ESMG401ELL3R3MJC5S from Chemi-Con is the recommended selection. This part maintains identical mechanical dimensions, lead spacing, and electrical specifications while offering Active product status and ROHS3 compliance. The increased ripple current capability at high frequency (135 mA @ 100 kHz) provides additional performance headroom.

ESMG351ELL3R3MHB5D is not mechanically compatible due to different lead spacing (0.138" vs. 0.197"), smaller diameter (0.315" vs. 0.394"), and reduced height (0.512" vs. 0.551"). This part is listed as a similar electrical equivalent only and requires PCB layout modification for implementation.

Frequently Asked Questions (FAQ)

Q: Can UVR2G3R3MPD be used as a direct replacement for UVR2V3R3MPD?

A: Yes. UVR2G3R3MPD is mechanically and electrically compatible. All physical dimensions, lead spacing, capacitance, tolerance, and operating temperature range are identical. The 400 V rating exceeds the 350 V requirement, providing additional voltage margin. Both parts are ROHS3 compliant.

Q: What is the difference between the upgrade and similar categories?

A: Upgrade parts (UVR2G3R3MPD and ESMG401ELL3R3MJC5S) maintain identical mechanical dimensions and lead spacing, enabling direct PCB substitution without layout modification. The similar part (ESMG351ELL3R3MHB5D) has different lead spacing and physical dimensions, requiring PCB redesign for implementation.

Q: Is ESMG401ELL3R3MJC5S suitable for new designs?

A: Yes. ESMG401ELL3R3MJC5S carries Active product status, indicating current manufacturing support and suitability for new designs. It maintains all mechanical and electrical compatibility with UVR2V3R3MPD while offering improved ripple current performance at high frequencies.

Q: What are the mechanical constraints for substitution?

A: Direct substitution requires exact matching of lead spacing (0.197" / 5.00mm), diameter (0.394" / 10.00mm), and height (0.551" / 14.00mm). Parts with different dimensions require PCB layout modification and are not considered direct replacements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the environmental compliance profile of the original UVR2V3R3MPD.
