UMP1C330MDD Equivalent & Substitute Parts

Part Overview

The UMP1C330MDD is a 33 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C, suitable for general-purpose applications requiring bi-polar aluminum electrolytic capacitance.

Substitute Part Grouping Explanation

Substitution eligibility for the UMP1C330MDD is determined by the following critical parameters: capacitance value (33 µF), voltage rating (16 V), tolerance (±20%), polarization type (bi-polar), and package configuration (radial, can). All identified substitute parts match these core electrical specifications. The substitutes are grouped into two categories based on mounting technology:

Category 1: Through-Hole Radial Substitutes — Parts maintaining the original through-hole mounting configuration with compatible physical dimensions and lead spacing suitable for PCB insertion.

Category 2: Surface-Mount Alternative — A part offering equivalent electrical performance with surface-mount technology, requiring different PCB land pattern design.

Engineering Selection Recommendations

For Through-Hole PCB Designs: ECE-A1CN330UB and ECE-A1CN330U are direct functional equivalents with active product status and ROHS3 compliance. Both Panasonic parts maintain identical electrical specifications and operating temperature ranges as the original UMP1C330MDD. ECE-A1CN330UB is packaged in Tape & Box format, while ECE-A1CN330U is supplied in bulk packaging. Physical dimensions differ slightly; verify lead spacing and case diameter compatibility with existing PCB footprints before selection.

For Surface-Mount PCB Designs: UUP1C330MCL1GS provides equivalent capacitance and voltage rating with extended operating temperature range (-55°C to 105°C) and active product status. This part requires surface-mount PCB land pattern design and is supplied in Tape & Reel packaging. The reduced lifetime rating (1000 Hrs @ 105°C versus 2000 Hrs @ 85°C) reflects operation at elevated temperatures and should be evaluated against application thermal profiles.

All substitute parts carry ROHS3 compliance and REACH unaffected status, maintaining regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can ECE-A1CN330UB directly replace UMP1C330MDD in existing designs?

A: Yes, for through-hole PCB applications. Both parts share identical capacitance (33 µF), voltage rating (16 V), tolerance (±20%), and operating temperature range (-40°C to 85°C). Verify lead spacing and case diameter compatibility with your PCB footprint. ECE-A1CN330UB uses 0.197" (5.00 mm) lead spacing versus UMP1C330MDD's 0.098" (2.50 mm) spacing.

Q: What is the difference between ECE-A1CN330U and ECE-A1CN330UB?

A: Both are electrically identical Panasonic parts with the same capacitance, voltage, and performance specifications. The primary difference is packaging: ECE-A1CN330UB is supplied in Tape & Box format, while ECE-A1CN330U is supplied in bulk. Select based on procurement and assembly requirements.

Q: Is UUP1C330MCL1GS suitable for my through-hole design?

A: No. UUP1C330MCL1GS is a surface-mount component requiring SMD PCB land patterns and reflow soldering. It is not compatible with through-hole PCB designs. Use ECE-A1CN330UB or ECE-A1CN330U for through-hole applications.

Q: Why does UUP1C330MCL1GS have a lower lifetime rating?

A: UUP1C330MCL1GS is rated at 1000 Hrs @ 105°C, compared to 2000 Hrs @ 85°C for the original part. This reflects the component's performance at elevated operating temperatures. Evaluate your application's thermal environment to determine if this rating is acceptable.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts (ECE-A1CN330UB, ECE-A1CN330U, and UUP1C330MCL1GS) are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance with the original UMP1C330MDD.
