Equivalent & Substitute Parts for UPS1C331MPD1TD

Part Overview

The UPS1C331MPD1TD is a 330 µF, 16 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has been superseded in the product lifecycle. The UPS series offers a 2000-hour lifetime rating at 105°C with general-purpose applications. Due to its discontinued status for new designs, equivalent and substitute parts with improved specifications or active product status are available to maintain design continuity and ensure long-term component availability.

Substitute Part Grouping Explanation

Substitution for the UPS1C331MPD1TD is determined by strict equivalence in the following parameters: capacitance (330 µF), voltage rating (16 V), tolerance (±20%), physical dimensions (0.315" diameter, 0.512" height, 0.138" lead spacing), mounting type (through hole radial), and polarization (polar). Substitute parts are grouped into three categories:

Direct Equivalents (Packaging Variation): UPS1C331MPD differs only in packaging format (bulk versus cut tape) while maintaining identical electrical and mechanical specifications.

Upgraded Equivalents (Enhanced Lifetime): UPA1C331MPD1TD, UPW1C331MPD1TD, UPW1C331MPD1TA, 860080374011, and EEU-FC1C331BJ maintain the same capacitance, voltage, and physical dimensions but offer extended lifetime ratings (3000 to 4000 hours at 105°C) and active product status. These parts are pin-compatible and dimensionally identical.

Voltage-Upgraded Equivalents: UKA1E331MPD1TD and UPA1E331MPD1TD provide the same capacitance and physical form factor but with increased voltage rating (25 V instead of 16 V). These are suitable for applications requiring higher voltage margin while maintaining backward compatibility in 16 V circuits.

Engineering Selection Recommendations

For Direct Replacement with Active Product Status: UPA1C331MPD1TD is the primary recommendation. It maintains identical electrical and mechanical specifications to the UPS1C331MPD1TD while offering extended lifetime (3000 hours versus 2000 hours at 105°C) and active product status. This part is ROHS3 compliant and suitable for general-purpose applications.

For Extended Lifetime Requirements: 860080374011 (Würth Elektronik WCAP-ATLI series) and 860160374020 (Würth Elektronik WCAP-ATLL series) provide 3000 and 4000-hour lifetimes respectively at 105°C. Both are active products with ROHS3 compliance. The 860080374011 offers superior impedance characteristics (80 mOhms) compared to the original part.

For Automotive Applications: EEU-FC1C331BJ (Panasonic FC series) is an active product with AEC-Q200 rating, suitable for automotive-grade requirements. It maintains the same capacitance and voltage specifications with ROHS3 compliance, though height is slightly reduced (0.492" versus 0.512").

For Higher Voltage Margin: UPA1E331MPD1TD provides 25 V rating with 3000-hour lifetime and active status. This part is suitable for circuits where increased voltage headroom is beneficial while maintaining the same physical footprint and capacitance value.

For Packaging Flexibility: UPS1C331MPD (bulk packaging) is electrically and mechanically identical to UPS1C331MPD1TD but supplied in bulk format rather than cut tape.

Frequently Asked Questions (FAQ)

Q: Can UPA1C331MPD1TD be used as a direct replacement for UPS1C331MPD1TD?

A: Yes. UPA1C331MPD1TD is a direct replacement. Both parts share identical capacitance (330 µF), voltage rating (16 V), tolerance (±20%), physical dimensions (0.315" diameter, 0.512" height, 0.138" lead spacing), and mounting type (through hole radial). UPA1C331MPD1TD offers improved lifetime (3000 hours versus 2000 hours at 105°C) and active product status.

Q: What is the difference between UPS1C331MPD1TD and UPS1C331MPD?

A: The parts are electrically and mechanically identical. The only difference is packaging: UPS1C331MPD1TD is supplied in cut tape format, while UPS1C331MPD is supplied in bulk. Both have identical specifications and are not recommended for new designs.

Q: Can I use a 25 V rated capacitor (UPA1E331MPD1TD) in a 16 V circuit?

A: Yes. UPA1E331MPD1TD is rated for 25 V and can be used in 16 V circuits. The higher voltage rating provides additional safety margin. Physical dimensions and capacitance remain identical to the original part.

A: Impedance varies among substitutes: UPS1C331MPD1TD (280 mOhms), UPA1C331MPD1TD (90 mOhms), UPW1C331MPD1TD (117 mOhms), 860080374011 (80 mOhms), 860160374020 (370 mOhms), and EEU-FC1C331BJ (117 mOhms). Lower impedance generally indicates better high-frequency performance. Selection depends on circuit requirements for ripple current handling and frequency response.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and suitable for applications requiring RoHS compliance.

Q: Which substitute offers the longest lifetime at 105°C?

A: 860160374020 (Würth Elektronik) offers the longest lifetime at 4000 hours at 105°C. UPA1C331MPD1TD and 860080374011 both offer 3000-hour lifetimes.

Q: Can I use EEU-FC1C331BJ in non-automotive applications?

A: Yes. EEU-FC1C331BJ is an active product with AEC-Q200 automotive qualification but is suitable for general-purpose applications. Its specifications match the original part except for slightly reduced height (0.492" versus 0.512").
