UVZ1J331MPH Equivalent & Substitute Parts

Part Overview

The UVZ1J331MPH is a 330 µF, 63 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete and no longer recommended for new designs. The UVZ series has been superseded by newer product lines with improved reliability ratings and enhanced compliance certifications. Identifying equivalent and substitute parts is essential for maintaining circuit functionality in legacy systems and for design transitions to active product alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UVZ1J331MPH is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 330 µF
• Voltage Rating: 63 V
• Tolerance: ±20%
• Operating Temperature Range: -55°C ~ 105°C
• Polarization: Polar
• Mounting Type: Through Hole
• Package Type: Radial, Can
• Lead Spacing: 0.197" (5.00mm)
• Case Diameter: 0.394" (10.00mm)

Acceptable Variation Parameters:

• Lifetime @ 105°C: 1000 Hrs minimum (original specifies 2000 Hrs)
• Height (Seated Max): 0.846" to 0.866" (original 0.866")
• Ripple Current: Values within operational tolerance
• Case Diameter: 0.394" to 0.512" (slight dimensional variation acceptable for legacy applications)

Substitute parts are classified into three categories: Direct Manufacturer equivalents (same series, different packaging or status), Parametric Equivalents (different manufacturer, identical electrical specifications), and Upgrades (enhanced performance characteristics while maintaining core parameters).

Parameter Comparison

Engineering Selection Recommendations

For Legacy System Maintenance (Direct Replacement): UVZ1J331MPD and UVY1J331MPD are the closest direct replacements from Nichicon. Both maintain identical electrical and mechanical specifications to the original UVZ1J331MPH while providing ROHS3 compliance. These parts are classified as "Not For New Designs" but remain suitable for sustaining existing equipment.

For Active Product Alternatives: ECA-1JHG331 and ECA-1JHG331E from Panasonic are parametric equivalents with active product status and full ROHS3 compliance. These parts match all critical electrical parameters and physical dimensions, making them suitable for design transitions and new applications requiring 330 µF, 63 V aluminum electrolytic capacitors.

For Enhanced Ripple Current Performance: SEK331M063ST from Cornell Dubilier Electronics offers higher ripple current ratings (650 mA @ 120 Hz, 910 mA @ 10 kHz) compared to the original specification. This part accommodates applications with elevated AC current demands while maintaining the same capacitance, voltage, and temperature specifications. Note the case diameter is 0.512" versus the standard 0.394", requiring PCB layout verification.

For Chemi-Con Sourcing: EKMQ630ELL331MJ20S provides 2000 Hrs @ 105°C lifetime matching the original specification with active product status and ROHS3 compliance. EKMG630ELL331MJ20S offers the same electrical performance with 1000 Hrs @ 105°C lifetime, suitable for applications with reduced lifetime requirements.

For Rubycon Sourcing: 63PX330MEFC10X20 is an active product with 2000 Hrs @ 105°C lifetime and ROHS3 compliance. Ripple current specifications differ slightly (540 mA @ 120 Hz, 648 mA @ 10 kHz), requiring thermal analysis for applications operating at maximum ripple current limits.

Frequently Asked Questions (FAQ)

Q: Can UVZ1J331MPH be directly replaced with ECA-1JHG331? A: Yes. Both parts share identical capacitance (330 µF), voltage rating (63 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), operating temperature range (-55°C ~ 105°C), lead spacing (0.197"), case diameter (0.394"), and height (0.866"). Electrical performance and physical footprint are equivalent. ECA-1JHG331 has active product status and ROHS3 compliance.

Q: What is the difference between UVZ1J331MPD and UVY1J331MPD? A: Both are Nichicon products with identical electrical and mechanical specifications. The primary difference is the product series designation (UVZ versus UVY). Both are classified as "Not For New Designs" but provide ROHS3 compliance. Selection between these parts depends on inventory availability and internal design documentation requirements.

Q: Is SEK331M063ST a suitable replacement despite the larger case diameter? A: SEK331M063ST has a case diameter of 0.512" compared to the standard 0.394". While all electrical parameters match, the larger physical footprint requires PCB layout verification to confirm clearance around the component location. This part is suitable only if mechanical space permits the larger diameter.

Q: What is the significance of "Not For New Designs" status? A: Parts marked "Not For New Designs" are transitional products that remain available for existing applications but are not recommended for new circuit designs. Manufacturers typically apply this status when a product line is being phased out in favor of newer alternatives. For new designs, select parts with "Active" product status such as ECA-1JHG331, EKMQ630ELL331MJ20S, or 63PX330MEFC10X20.

Q: Does ripple current variation affect substitution suitability? A: Ripple current specifications indicate the AC current the capacitor can safely handle. Higher ripple current ratings (such as SEK331M063ST at 650 mA @ 120 Hz) provide additional thermal margin but do not prevent substitution in applications with lower ripple current demands. Lower ripple current ratings require thermal analysis to confirm the capacitor does not exceed temperature limits during operation.

Q: Are all substitute parts ROHS3 compliant? A: All substitute parts listed are ROHS3 compliant. The original UVZ1J331MPH is RoHS non-compliant. If RoHS compliance is a requirement for your application, any of the listed substitutes satisfy this criterion.

Q: Can EKMG630ELL331MJ20S be used if the application requires 2000 Hrs @ 105°C lifetime? A: EKMG630ELL331MJ20S specifies 1000 Hrs @ 105°C lifetime, which is half the original specification. This part is suitable only for applications where the reduced lifetime is acceptable. For applications requiring 2000 Hrs @ 105°C, select EKMQ630ELL331MJ20S, ECA-1JHG331, ECA-1JHG331E, 63PX330MEFC10X20, or SEK331M063ST.

Q: What packaging options are available for these substitutes? A: All substitute parts are supplied in bulk packaging except where noted. Packaging format does not affect electrical or mechanical compatibility; it reflects the quantity and presentation method from the manufacturer. Confirm packaging requirements with your procurement process.
