Equivalent & Substitute Parts for UAQ2D330MPD

Part Overview

The UAQ2D330MPD is a 33 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 2000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production.

Equivalent and substitute parts are necessary when the original UAQ2D330MPD becomes unavailable, when design requirements demand extended operational lifetime, or when alternative manufacturers' components meet the same electrical and mechanical specifications. Substitutes must maintain identical capacitance, voltage rating, polarization, and physical compatibility while meeting RoHS3 compliance requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the UAQ2D330MPD is determined by the following mandatory parameters:

Capacitance: Must be 33 µF
Voltage Rating: Must be 200 V
Tolerance: Must be ±20%
Polarization: Must be Polar
Package Type: Must be Radial, Can
Mounting Type: Must be Through Hole
Lead Spacing: Must be 0.197" (5.00 mm)
Operating Temperature Range: Must be -40°C to 105°C
RoHS Compliance: Must be ROHS3 Compliant

All substitute parts listed meet these core requirements. Secondary parameters such as lifetime rating, ripple current capacity, physical dimensions (diameter and height), and manufacturer identity do not disqualify a part from substitution but may influence selection based on application-specific requirements.

Engineering Selection Recommendations

Primary Selection: UCS2D330MPD (Nichicon) is the recommended direct substitute. This part maintains identical electrical specifications and physical lead spacing while offering extended lifetime (8000 hours at 105°C versus 2000 hours). The part is Active in production status and ROHS3 compliant. The reduced height (0.846" versus 1.063") provides improved board layout flexibility.

Alternative Selection: EKXG201ELL330MJ20S (Chemi-Con) is an active, ROHS3-compliant alternative from a different manufacturer. This part provides equivalent electrical performance with 8000-hour lifetime rating and the most compact height (0.787"). Selection of this part requires cross-manufacturer qualification in the design documentation.

Conditional Selection: UVY2D330MPD (Nichicon) meets all core substitution criteria but carries "Not For New Designs" status. This part is suitable only for legacy system maintenance or repair applications where the original UAQ2D330MPD is unavailable.

Not Recommended: UPW2D330MHD (Nichicon) is obsolete and features a larger diameter (0.492" versus 0.394"), which may create board layout conflicts. This part should be avoided for new applications.

Frequently Asked Questions (FAQ)

Q: Can UCS2D330MPD be used as a direct replacement for UAQ2D330MPD?

A: Yes. Both parts share identical capacitance (33 µF), voltage rating (200 V), tolerance (±20%), lead spacing (5.00 mm), and operating temperature range (-40°C to 105°C). The UCS2D330MPD is physically shorter (0.846" versus 1.063"), which is compatible with standard through-hole PCB layouts designed for the UAQ2D330MPD.

Q: What is the difference between the Nichicon and Chemi-Con options?

A: Both manufacturers provide 33 µF, 200 V radial capacitors with identical electrical ratings and lead spacing. The primary differences are manufacturer identity, physical height, and lifetime rating. EKXG201ELL330MJ20S (Chemi-Con) offers the most compact form factor at 0.787" height. Cross-manufacturer substitution requires design team approval and qualification testing per company standards.

Q: Why is UPW2D330MHD not recommended?

A: The UPW2D330MHD is marked as Obsolete and features a larger diameter (0.492" versus 0.394"), which may not fit existing PCB footprints designed for the UAQ2D330MPD. Obsolete parts present supply chain risk and should be avoided for new designs.

Q: Can I use UVY2D330MPD in a new design?

A: No. The UVY2D330MPD carries "Not For New Designs" status. This part is restricted to legacy system maintenance only. For new designs, select UCS2D330MPD or EKXG201ELL330MJ20S.

Q: Does lead spacing affect PCB compatibility?

A: All substitute parts listed maintain 0.197" (5.00 mm) lead spacing, which is compatible with standard through-hole PCB designs for the UAQ2D330MPD. Physical diameter and height may vary; verify PCB clearance for parts with larger dimensions (such as UPW2D330MHD at 0.492" diameter).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts listed in this reference are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
