UHE1V331MPD1CA Equivalent & Substitute Parts

Part Overview

The UHE1V331MPD1CA is a 330 µF, 35 V aluminum electrolytic capacitor manufactured by Nichicon in the UHE series. This radial, through-hole component is rated for 7000 hours at 105°C and operates across a temperature range of -40°C to 105°C. The part is currently active in production. Equivalent substitute parts are identified when they maintain identical electrical specifications and mechanical compatibility, enabling direct replacement in applications where the original part becomes unavailable or when inventory optimization is required.

Substitute Part Grouping Explanation

Substitution eligibility for the UHE1V331MPD1CA is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 35 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime rating: 7000 Hrs @ 105°C (exact match required)
• Operating temperature range: -40°C to 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: 0.689" (17.50 mm) (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)

The EKY-350ELL331MJ16S from Chemi-Con meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the UHE1V331MPD1CA and EKY-350ELL331MJ16S are active production components with identical electrical and mechanical specifications. The EKY-350ELL331MJ16S carries ROHS3 compliance certification. Selection between these parts should be based on availability, packaging format (the Nichicon part is supplied in Cut Tape; the Chemi-Con part is supplied in Bulk), and organizational procurement requirements. Both parts are suitable for general-purpose applications requiring 330 µF capacitance at 35 V with 7000-hour lifetime ratings at 105°C.

Frequently Asked Questions (FAQ)

Q: Can the EKY-350ELL331MJ16S replace the UHE1V331MPD1CA in existing designs?

A: Yes. Both parts share identical capacitance, voltage rating, tolerance, lifetime rating, operating temperature range, and mechanical dimensions. Direct substitution is supported without circuit redesign.

Q: Are there differences in ripple current handling between these parts?

A: Both parts are rated for 1.21 A ripple current at 100 kHz. The low-frequency ripple current specification differs (847 mA for the Nichicon part versus 605 mA for the Chemi-Con part), but this does not affect substitution eligibility as both meet the high-frequency requirement.

Q: What is the difference between Cut Tape and Bulk packaging?

A: Cut Tape packaging is supplied on continuous tape cut to specific lengths, suitable for automated assembly. Bulk packaging is supplied loose in containers, typically used for manual assembly or reel consolidation. Both packaging formats contain identical components.

Q: Do both parts meet RoHS requirements?

A: The EKY-350ELL331MJ16S is certified ROHS3 compliant. RoHS status for the UHE1V331MPD1CA is not specified in the provided data.

Q: Are these parts suitable for high-temperature applications?

A: Both parts are rated for continuous operation at 105°C with a 7000-hour lifetime at this temperature. They are suitable for applications within this thermal specification.
