UVR1C331MPD1CM Equivalent & Substitute Parts

Part Overview

The UVR1C331MPD1CM is a 330 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 2000 hours at 85°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 primary part becomes unavailable, when design revisions require alternative manufacturers, or when inventory constraints necessitate compatible alternatives that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the UVR1C331MPD1CM are qualified based on strict equivalence of the following parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 16 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime: 2000 Hrs @ 85°C (exact match required)
Operating Temperature Range: -40°C ~ 85°C (exact match required)
Polarization: Polar (exact match required)
Ripple Current @ 120 Hz: 370 mA (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)
Lead Spacing: 0.138" (4.60 mm) (exact match required)
Size / Dimension: 0.315" Dia (8.00 mm) (exact match required)
Height - Seated (Max): 0.512" (13.00 mm) (exact match required)

All identified substitutes meet these criteria and are therefore electrically and mechanically interchangeable with the primary part.

Engineering Selection Recommendations

UVR1C331MPD1CM is the primary specification part with active product status. For new designs, this part is the preferred selection.

UVR1C331MPD is a Nichicon equivalent with identical electrical and mechanical parameters. However, this part carries a "Not For New Designs" status, indicating it is in end-of-life phase. Use this part only for legacy system maintenance or when existing inventory is available and cost considerations justify its use.

ESMG160ELL331MHB5D is manufactured by Chemi-Con and maintains active product status. This part is electrically and mechanically equivalent to the primary part and carries ROHS3 compliance and REACH unaffected certification. This part is suitable for new designs and provides an alternative source from a different manufacturer.

Frequently Asked Questions (FAQ)

Q: Can UVR1C331MPD be used as a direct replacement for UVR1C331MPD1CM?

A: Yes. Both parts are manufactured by Nichicon and share identical electrical specifications (330 µF, 16 V, ±20%, 2000 Hrs @ 85°C) and mechanical dimensions (0.315" Dia, 0.512" height, 0.138" lead spacing). The primary difference is product status; UVR1C331MPD is marked "Not For New Designs." For legacy applications, this substitution is valid.

Q: Is ESMG160ELL331MHB5D compatible with UVR1C331MPD1CM in existing PCB designs?

A: Yes. ESMG160ELL331MHB5D is manufactured by Chemi-Con and meets all electrical and mechanical requirements. Lead spacing, package dimensions, and mounting type are identical. This part is suitable for direct PCB substitution without layout modifications.

Q: What are the key parameters that determine substitutability for this capacitor?

A: Substitutability is determined by exact equivalence in capacitance (330 µF), voltage rating (16 V), tolerance (±20%), lifetime rating (2000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), ripple current specifications (370 mA @ 120 Hz, 555 mA @ 10 kHz), and mechanical dimensions (0.315" Dia, 0.512" height, 0.138" lead spacing). All identified substitutes meet these criteria.

Q: Are there compliance differences between the substitute parts?

A: ESMG160ELL331MHB5D and UVR1C331MPD both carry ROHS3 compliance and REACH unaffected certification. UVR1C331MPD1CM compliance status is not specified in the provided data. For applications requiring documented compliance, ESMG160ELL331MHB5D or UVR1C331MPD are appropriate selections.

Q: Can these parts be used interchangeably in high-ripple-current applications?

A: Yes. All three parts are rated for identical ripple current specifications: 370 mA @ 120 Hz and 555 mA @ 10 kHz. They are therefore interchangeable in applications requiring these ripple current ratings.
