UVZ1H331MPD1AA Equivalent & Substitute Parts

Part Overview

The UVZ1H331MPD1AA is a 330 µF, 50 V aluminum electrolytic capacitor manufactured by Nichicon in the UVZ series. This radial, through-hole component is rated for 2000 hours at 105°C and is designed for general-purpose applications. The part is currently active in production. Equivalent and substitute parts become necessary when the primary part experiences supply constraints, when design revisions require alternative manufacturers, or when legacy series components require modern replacements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the UVZ1H331MPD1AA is determined by strict equivalence across the following critical parameters:

Capacitance Value: 330 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime Rating: 2000 Hrs @ 105°C (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Package Diameter: 0.394" (10.00 mm) (exact match required)
Height - Seated (Max): 0.689" (17.50 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)

All identified substitute parts meet these criteria across different manufacturers and series designations. Ripple current specifications may vary within acceptable ranges for the same electrical classification.

Engineering Selection Recommendations

For Active Production Designs: The 50PX330MEFC10X16 (Rubycon PX series) and EEU-HD1H331 (Panasonic HD series) are both active products and represent the primary substitution options. Both maintain full parametric equivalence with the UVZ1H331MPD1AA and carry ROHS3 compliance certification.

For Legacy or Existing Designs: The UVZ1H331MPD (non-dated variant) and UVY1H331MPD are parametrically equivalent Nichicon alternatives, though both are marked as "Not For New Designs." These remain suitable for replacement in existing applications where the UVZ1H331MPD1AA is no longer available.

For Nichicon-Specific Requirements: The UKA1H331MPD is a Nichicon substitute within the same manufacturer family, though it is also designated "Not For New Designs." This part maintains full electrical and mechanical compatibility.

All substitute parts are ROHS3 compliant and meet the specified electrical and mechanical parameters for direct board-level substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can I substitute the UVZ1H331MPD1AA with any of these parts without circuit modification?

A: Yes. All listed substitute parts are parametrically equivalent across capacitance, voltage rating, tolerance, lifetime rating, operating temperature range, and mechanical dimensions. Direct substitution on the PCB is possible without circuit redesign.

Q: What is the difference between UVZ1H331MPD1AA and UVZ1H331MPD?

A: Both are Nichicon UVZ series 330 µF, 50 V capacitors with identical electrical and mechanical specifications. The primary difference is product status: UVZ1H331MPD1AA is active, while UVZ1H331MPD is marked "Not For New Designs." For new designs, UVZ1H331MPD1AA is the preferred part number.

Q: Are there any ripple current differences I should consider?

A: Ripple current specifications vary slightly among manufacturers. The UVZ1H331MPD1AA and EEU-HD1H331 both specify 615 mA @ 10 kHz. The 50PX330MEFC10X16 specifies 470 mA @ 120 Hz. All values remain within acceptable operating ranges for the 330 µF, 50 V classification.

Q: Can I use the Rubycon 50PX330MEFC10X16 in place of the Nichicon UVZ1H331MPD1AA?

A: Yes. The Rubycon part is parametrically equivalent and is currently active in production. It maintains the same lead spacing, package diameter, height, and electrical ratings, making it suitable for direct substitution.

Q: What does "Not For New Designs" mean for the UKA1H331MPD and UVY1H331MPD?

A: This designation indicates that these parts are legacy or end-of-life series from Nichicon. While they remain parametrically equivalent and suitable for replacement in existing applications, they should not be selected for new product designs. For new designs, choose UVZ1H331MPD1AA, 50PX330MEFC10X16, or EEU-HD1H331.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting current environmental and regulatory requirements.
