UPB1A331MPD1TA Equivalent & Substitute Parts

Part Overview

The UPB1A331MPD1TA is a 330 µF, 10 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The UPB series has been superseded by active production alternatives that maintain the same electrical and mechanical specifications while offering improved availability and extended operational lifetime ratings.

Substitute Part Grouping Explanation

Substitute parts for the UPB1A331MPD1TA are grouped based on strict electrical and mechanical compatibility criteria:

Direct Substitutes (Identical Specifications): Parts that maintain the same capacitance (330 µF), voltage rating (10 V), tolerance (±20%), lead spacing (0.138" / 4.60mm), physical dimensions (0.315" Dia × 0.512" Height), and through-hole radial can package are classified as direct substitutes. These parts are interchangeable at the board level without design modification.

Voltage-Rated Alternatives: Parts with higher voltage ratings (25 V) but identical capacitance, tolerance, and physical dimensions are listed as alternatives. These provide enhanced voltage margin in applications where the original 10 V rating is sufficient but higher voltage headroom is desired.

Lead Spacing Variants: Parts with modified lead spacing (0.197" / 5.00mm instead of 0.138" / 4.60mm) require PCB layout adjustment and are not direct substitutes without board redesign.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (No PCB Modification Required):

The 10YXM330MEFRT78X11.5 (Rubycon) and 860240274006 (Würth Elektronik) are direct electrical and mechanical substitutes for the UPB1A331MPD1TA. Both parts maintain identical lead spacing (0.138" / 4.60mm), physical dimensions, and voltage rating (10 V). Both manufacturers provide ROHS3 compliance and REACH unaffected status. The Rubycon part offers extended lifetime (10000 Hrs @ 105°C versus 5000 Hrs), while the Würth Elektronik part provides 8000 Hrs @ 105°C. Both are suitable for direct board-level replacement without design changes.

Voltage-Rated Alternative (No PCB Modification Required):

The UTT1E331MPD1TA (Nichicon) maintains identical lead spacing and physical dimensions but provides a higher voltage rating (25 V). This part is suitable for applications where voltage margin enhancement is beneficial. It is ROHS3 compliant and REACH unaffected. Selection of this part does not require PCB layout modification.

Lead Spacing Variant (PCB Modification Required):

The 10YXM330MEFRTA8X11.5 (Rubycon) features modified lead spacing (0.197" / 5.00mm) and requires PCB footprint adjustment. This part is not recommended for direct substitution without board redesign.

Frequently Asked Questions (FAQ)

Q: Can the UTT1E331MPD1TA (25 V) be used in place of the UPB1A331MPD1TA (10 V)?

A: Yes. The UTT1E331MPD1TA maintains identical capacitance (330 µF), tolerance (±20%), lead spacing (0.138" / 4.60mm), and physical dimensions. The higher voltage rating (25 V) does not create compatibility issues in applications designed for 10 V operation. No PCB modification is required.

Q: What is the difference between the two Rubycon YXM series parts?

A: Both Rubycon parts (10YXM330MEFRT78X11.5 and 10YXM330MEFRTA8X11.5) share identical electrical specifications and lifetime ratings (10000 Hrs @ 105°C). The primary difference is lead spacing: the first part uses 0.138" (4.60mm) spacing, matching the original UPB1A331MPD1TA, while the second uses 0.197" (5.00mm) spacing. Only the first part is a direct substitute without PCB modification.

Q: Are all substitute parts RoHS compliant?

A: The active production substitutes (UTT1E331MPD1TA, 10YXM330MEFRT78X11.5, 10YXM330MEFRTA8X11.5, and 860240274006) are ROHS3 compliant. The original UPB1A331MPD1TA does not specify RoHS status due to its obsolete classification.

Q: Which substitute part offers the longest operational lifetime?

A: The Rubycon YXM series parts (both 10YXM330MEFRT78X11.5 and 10YXM330MEFRTA8X11.5) provide 10000 Hrs @ 105°C, compared to 5000 Hrs for the original part and 8000 Hrs for the Würth Elektronik part.

Q: Can I use the 860240274006 (Würth Elektronik) as a direct replacement?

A: Yes. The 860240274006 maintains identical lead spacing (0.138" / 4.60mm), physical dimensions, voltage rating (10 V), and capacitance (330 µF). It is a direct electrical and mechanical substitute requiring no PCB modification.
