UPM1E331MPD1CM Equivalent & Substitute Parts

Part Overview

The UPM1E331MPD1CM is a 330 µF, 25 V aluminum electrolytic capacitor manufactured by Nichicon in a radial, can package. This component is rated for automotive applications with AEC-Q200 compliance and operates across a temperature range of -55°C to 105°C with a 3000-hour lifetime at 105°C. The part is currently active in production and available in bulk packaging with 898 units in stock.

Equivalent and substitute parts become necessary when the primary part number reaches end-of-life status, experiences supply constraints, or when design flexibility allows for alternative manufacturers meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the UPM1E331MPD1CM is determined by strict parametric matching across the following criteria:

Capacitance: 330 µF (exact match required)
Voltage Rating: 25 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime: 3000 Hrs @ 105°C (exact match required)
Operating Temperature: -55°C to 105°C (exact match required)
Polarization: Polar (exact match required)
Package: Radial, Can (exact match required)
Lead Spacing: 0.138" (4.60 mm) (exact match required)
Physical Dimensions: 0.315" Dia × 0.846" Height (exact match required)
Mounting: Through Hole (exact match required)
Automotive Compliance: AEC-Q200 (exact match required)

All identified substitute parts meet these criteria. Variations in ripple current ratings and impedance values do not disqualify substitution when all primary electrical and mechanical parameters align.

Engineering Selection Recommendations

UPM1E331MPD (Nichicon): This part is a direct parametric equivalent to the UPM1E331MPD1CM with identical electrical and mechanical specifications. However, its product status is listed as "Not For New Designs," indicating it is in mature or declining production phase. Selection of this substitute should be limited to legacy system maintenance or when existing design validation has already been completed with this part number.

ELXV250ELL331MH20D (Chemi-Con): This substitute maintains full parametric equivalence and carries an active product status. It is RoHS3 compliant and rated for automotive applications with AEC-Q200 certification. The REACH status is listed as unaffected. This part is suitable for new designs and ongoing production applications.

ELXY250ELL331MH20D (Chemi-Con): This substitute also maintains full parametric equivalence with active product status, RoHS3 compliance, and AEC-Q200 automotive rating. REACH status is unaffected. This part is suitable for new designs and ongoing production applications.

For new design implementations, either Chemi-Con substitute (ELXV250ELL331MH20D or ELXY250ELL331MH20D) is preferred due to active product status and confirmed RoHS3 compliance. The Nichicon UPM1E331MPD should be reserved for legacy system support only.

Frequently Asked Questions (FAQ)

Q: Can ELXV250ELL331MH20D and ELXY250ELL331MH20D be used interchangeably with UPM1E331MPD1CM?

A: Yes. Both Chemi-Con parts meet all required electrical and mechanical parameters: 330 µF capacitance, 25 V voltage rating, ±20% tolerance, 3000-hour lifetime at 105°C, identical physical dimensions, lead spacing, and through-hole mounting configuration. Both are AEC-Q200 rated for automotive applications.

Q: What is the difference between the two Chemi-Con substitutes?

A: ELXV250ELL331MH20D and ELXY250ELL331MH20D differ in ripple current ratings and impedance values. ELXY250ELL331MH20D provides higher ripple current capacity at 370 mA @ 120 Hz and 740 mA @ 100 kHz, compared to ELXV250ELL331MH20D at 352 mA @ 120 Hz and 640 mA @ 100 kHz. Impedance values are 95 mOhms and 110 mOhms respectively. Selection between these two should be based on circuit ripple current requirements.

Q: Why is UPM1E331MPD marked "Not For New Designs"?

A: This designation indicates the part is in mature production phase with potential future discontinuation. While it remains functionally equivalent and suitable for legacy system maintenance, new product designs should utilize parts with active status to ensure long-term supply availability.

Q: Are all substitutes compatible with existing PCB layouts?

A: Yes. All substitute parts share identical lead spacing (0.138" / 4.60 mm), package diameter (0.315" / 8.00 mm), and maximum seated height (0.846" / 21.50 mm). No PCB layout modifications are required for substitution.

Q: Do the substitutes maintain automotive compliance?

A: Yes. All identified substitutes carry AEC-Q200 certification and are rated for automotive applications across the same operating temperature range (-55°C to 105°C).
