UHD1C331MPD1AA Equivalent & Substitute Parts

Part Overview

The UHD1C331MPD1AA is a 330 µF, 16 V aluminum electrolytic capacitor manufactured by Nichicon in a radial, can package configuration. This component is rated for 3000 hours of operation at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production status.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design flexibility is required across manufacturing sources, or when alternative product statuses better align with production timelines and supply chain requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the UHD1C331MPD1AA is determined by strict parametric equivalence across the following criteria:

• Capacitance value: 330 µF (exact match required)
• Rated voltage: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime rating: 3000 Hrs @ 105°C (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Physical dimensions: 0.315" Dia (8.00mm), 0.512" (13.00mm) height, 0.138" (4.60mm) lead spacing (exact match required)
• Mounting type: Through Hole, Radial, Can package (exact match required)
• Polarization: Polar (exact match required)

All three substitute parts meet these parametric requirements and are therefore classified as parametric equivalents suitable for direct substitution in applications designed for the UHD1C331MPD1AA.

Parameter Comparison

Engineering Selection Recommendations

UHD1C331MPD (Nichicon): This part is a parametric equivalent with identical electrical and mechanical specifications to the UHD1C331MPD1AA. However, its product status is listed as "Not For New Designs," indicating that Nichicon has designated this part for legacy applications only. Selection of this substitute should be limited to replacement or maintenance scenarios for existing designs.

16ZL330MEFC8X11.5 (Rubycon): This part meets all parametric requirements for direct substitution. Its product status is "Last Time Buy," indicating limited availability. This part is suitable for applications where Rubycon sourcing is preferred or where supply chain diversification is required, provided that procurement timelines account for potential availability constraints.

EEU-FM1C331 (Panasonic Electronic Components): This part is a parametric equivalent with active product status, indicating ongoing production and availability. The EEU-FM1C331 is suitable for new designs and applications requiring long-term supply assurance. This part represents the most favorable selection from a product lifecycle and availability perspective.

All three substitute parts are ROHS3 compliant and suitable for applications requiring regulatory compliance with environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the UHD1C331MPD1AA be replaced with any of these substitute parts in an existing design?

A: Yes. All three substitute parts are parametric equivalents meeting the identical electrical and mechanical specifications: 330 µF capacitance, 16 V rated voltage, ±20% tolerance, 3000 Hrs @ 105°C lifetime rating, and identical physical dimensions and lead spacing. Direct substitution is supported without circuit redesign.

Q: What is the difference between the UHD1C331MPD and the UHD1C331MPD1AA?

A: Both parts are manufactured by Nichicon and share identical electrical and mechanical parameters. The primary difference is product status: UHD1C331MPD1AA is active in production, while UHD1C331MPD is designated "Not For New Designs." For new applications, the UHD1C331MPD1AA is the preferred selection.

Q: Why is the 16ZL330MEFC8X11.5 marked as "Last Time Buy"?

A: "Last Time Buy" status indicates that Rubycon has announced the end of production for this part. Existing inventory may be available, but future procurement cannot be guaranteed. This part should be selected only when current stock is confirmed and supply chain planning accounts for the limited availability window.

Q: Are there any ripple current differences between these parts?

A: Ripple current specifications vary among the substitute parts. The EEU-FM1C331 (Panasonic) provides the highest ripple current ratings at 665 mA @ 120 Hz and 950 mA @ 100 kHz. The UHD1C331MPD (Nichicon) and UHD1C331MPD1AA provide 532 mA @ 120 Hz and 760 mA @ 100 kHz. The 16ZL330MEFC8X11.5 (Rubycon) provides 418 mA @ 120 Hz. Selection should account for application ripple current requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, meeting environmental and regulatory requirements for restricted substance use.

Q: Which substitute part should be selected for a new design?

A: The EEU-FM1C331 (Panasonic Electronic Components) is recommended for new designs due to its active product status, ensuring long-term availability and supply chain stability. This part meets all parametric requirements and provides the highest ripple current performance among the available substitutes.
