UHC1V330MDD Equivalent & Substitute Parts

Part Overview

The UHC1V330MDD is a 33 µF, 35 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 1000 hours at 105°C and is designed for through-hole mounting applications. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance requirements.

Substitute Part Grouping Explanation

Substitution for the UHC1V330MDD is determined by strict equivalence in the following parameters:

Capacitance: 33 µF (exact match required)
Voltage Rating: 35 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Substitute parts are grouped into two categories:

Direct Equivalents (Same Footprint): Parts with identical lead spacing (0.098" / 2.50mm) and physical dimensions (0.248" Dia / 6.30mm, 0.315" Height / 8.00mm). These provide pin-for-pin compatibility without PCB modification.

Functional Equivalents (Different Footprint): Parts with different lead spacing (0.079" / 2.00mm) and reduced physical dimensions (0.197" Dia / 5.00mm). These require PCB layout adjustment but maintain electrical equivalence.

Lifetime ratings and ripple current specifications may vary among substitutes while maintaining core electrical functionality.

Engineering Selection Recommendations

For Direct PCB Compatibility (No Layout Modification Required):

EKMA350ELL330MF07D is the primary substitute. It maintains identical lead spacing and physical dimensions as the UHC1V330MDD, providing pin-for-pin compatibility. This part is manufactured by Chemi-Con and holds Active product status with RoHS3 compliance. The extended operating temperature range (-55°C ~ 105°C) provides additional margin compared to the original part.

For Extended Lifetime Applications (PCB Layout Modification Required):

EEU-FR1V330 or EEU-FR1V330B are suitable for applications requiring extended operational life. Both are manufactured by Panasonic and rated for 5000 hours at 105°C. These parts hold Active product status with RoHS3 compliance. The EEU-FR1V330B variant in Cut Tape packaging offers the highest inventory availability (40,570 pcs). PCB layout modification is necessary due to different lead spacing and physical dimensions.

For Intermediate Lifetime Requirements (PCB Layout Modification Required):

UHD1V330MDD, EEU-FM1V330, or EKZE350ELL330ME11D provide 2000-hour lifetime ratings at 105°C. EEU-FM1V330 and EKZE350ELL330ME11D are Active products with RoHS3 compliance. These options balance cost and performance for applications not requiring maximum lifetime.

Frequently Asked Questions (FAQ)

Q: Can EKMA350ELL330MF07D be used as a direct replacement without PCB modification?

A: Yes. EKMA350ELL330MF07D maintains identical lead spacing (0.098" / 2.50mm) and physical dimensions (0.248" Dia / 6.30mm, 0.315" Height / 8.00mm) as the UHC1V330MDD, enabling direct substitution without PCB layout changes.

Q: What is the primary difference between UHD1V330MDD and UHE1V330MDD?

A: Both parts have different lead spacing (0.079" / 2.00mm) and physical dimensions compared to the original UHC1V330MDD. The UHE1V330MDD provides extended lifetime (5000 hours at 105°C) compared to UHD1V330MDD (2000 hours at 105°C). Both require PCB layout modification.

Q: Are all substitute parts RoHS3 compliant?

A: EKMA350ELL330MF07D, EEU-FM1V330, EEU-FR1V330, EEU-FR1V330B, and EKZE350ELL330ME11D are RoHS3 compliant. UHD1V330MDD and UHE1V330MDD are obsolete Nichicon parts with RoHS3 compliance status.

Q: What is the difference between EEU-FR1V330 and EEU-FR1V330B?

A: Both parts are electrically identical with 33 µF, 35 V ratings and 5000-hour lifetime at 105°C. The primary difference is packaging: EEU-FR1V330 is supplied in Bulk packaging, while EEU-FR1V330B is supplied in Cut Tape (CT) packaging. EEU-FR1V330B has significantly higher inventory availability (40,570 pcs vs. 1,172 pcs).

Q: Which substitute offers the best availability?

A: EEU-FR1V330B provides the highest inventory availability at 40,570 pieces in stock. This part is Active, RoHS3 compliant, and rated for 5000 hours at 105°C, making it suitable for high-volume production requirements.

Q: Do all substitutes maintain the same operating temperature range?

A: Most substitutes operate from -40°C to 105°C, matching the original UHC1V330MDD. EKMA350ELL330MF07D extends the lower operating limit to -55°C, providing additional thermal margin for cold environment applications.
