UVP1C331MPD Equivalent & Substitute Parts

Part Overview

The UVP1C331MPD is a 330 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This part is classified as Not For New Designs, making identification of equivalent alternatives essential for ongoing production and maintenance applications. The component is rated for 2000 hours at 85°C with bi-polar polarization and general-purpose applications. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct board-level replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: capacitance (330 µF), voltage rating (16 V), tolerance (±20%), lifetime rating (2000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), polarization (bi-polar), lead spacing (0.197" / 5.00 mm), package type (radial, can), and mounting type (through hole). Height variation within manufacturing tolerances and minor differences in ripple current specifications at specific frequencies do not preclude substitution. All identified substitutes meet or exceed these core electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

UVP1C331MPD1AA is the primary parametric equivalent, manufactured by Nichicon with identical electrical and mechanical specifications. This part carries Active product status, ensuring continued availability and supply chain stability compared to the Not For New Designs classification of the main part.

337BPS016M, manufactured by Cornell Dubilier / Illinois Capacitor, provides direct substitution with equivalent core parameters. This part is Active and ROHS3 compliant. Height dimension is 0.709" (18.00 mm), representing a 0.020" (0.50 mm) increase over the main part. This minor variation remains within typical PCB clearance tolerances for through-hole radial capacitors.

ECE-A1CN331U and ECE-A1CN331UB, both manufactured by Panasonic Electronic Components, are Active alternatives with ROHS3 compliance. Both maintain identical electrical specifications. ECE-A1CN331U is supplied in Bulk packaging, while ECE-A1CN331UB is supplied in Cut Tape (CT) packaging. Height dimensions are 0.630" (16.00 mm) and 0.669" (17.00 mm) respectively, both within acceptable mechanical tolerances. Ripple current at 120 Hz is specified as 330 mA, compared to 375 mA for the main part; this represents a conservative rating and does not restrict substitution.

All substitute parts are ROHS3 compliant and suitable for direct board-level replacement without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can UVP1C331MPD1AA be used as a direct replacement for UVP1C331MPD?

A: Yes. UVP1C331MPD1AA is a parametric equivalent manufactured by Nichicon with identical capacitance (330 µF), voltage rating (16 V), tolerance (±20%), lifetime (2000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), lead spacing (5.00 mm), and package type (radial, can). The primary advantage is Active product status versus Not For New Designs for the original part.

Q: Are there height differences between substitute parts?

A: Yes. The main part UVP1C331MPD has a maximum seated height of 0.689" (17.50 mm). Substitute parts vary: UVP1C331MPD1AA matches at 0.689" (17.50 mm); 337BPS016M is 0.709" (18.00 mm); ECE-A1CN331U is 0.630" (16.00 mm); ECE-A1CN331UB is 0.669" (17.00 mm). These variations fall within standard PCB design tolerances for through-hole radial capacitors and do not preclude substitution.

Q: What is the difference between ECE-A1CN331U and ECE-A1CN331UB?

A: Both parts are electrically and mechanically identical. The difference is packaging: ECE-A1CN331U is supplied in Bulk packaging, while ECE-A1CN331UB is supplied in Cut Tape (CT) packaging. Height dimension also differs slightly: 0.630" (16.00 mm) versus 0.669" (17.00 mm). Selection depends on procurement and assembly requirements.

Q: Can 337BPS016M replace UVP1C331MPD in audio applications?

A: Yes. 337BPS016M is specified for audio applications and meets all electrical and mechanical requirements for substitution. The part is rated for 2000 Hrs @ 85°C with equivalent ripple current handling at 120 Hz (375 mA). Height is 0.709" (18.00 mm), a 0.020" increase that remains within standard PCB clearance tolerances.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified substitute parts—UVP1C331MPD1AA, 337BPS016M, ECE-A1CN331U, and ECE-A1CN331UB—are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and assembly.
