336BPS025M Equivalent & Substitute Parts Reference

Part Overview

The 336BPS025M is a 33 µF, 25 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the BPS series. This radial, through-hole component is designed for audio applications and operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C. The part is currently active in production status with 732 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory depletion, or when design flexibility permits selection from qualified alternatives that meet identical electrical and mechanical specifications. The UVP1E330MED from Nichicon represents a direct functional equivalent, though it carries obsolete product status.

Substitute Part Grouping Explanation

Substitution eligibility for the 336BPS025M is determined by strict equivalence across the following parameters:

Electrical Parameters:

• Capacitance value: 33 µF (exact match required)
• Voltage rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Bi-Polar (exact match required)
• Operating temperature range: -40°C to 85°C (exact match required)
• Lifetime rating: 2000 Hrs @ 85°C (exact match required)

Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)
• Lead spacing: 0.098" (2.50 mm) (exact match required)
• Case diameter: 0.248" (6.30 mm) (exact match required)

Compliance Parameters:

• RoHS3 Compliant status (required for regulatory alignment)

The UVP1E330MED satisfies all electrical and mechanical equivalence criteria. Ripple current specifications differ between the main part and substitute; however, both parts meet the 2000-hour lifetime requirement at 85°C, indicating thermal design compatibility within the specified operating envelope.

Engineering Selection Recommendations

Primary Selection: 336BPS025M

The 336BPS025M remains the preferred selection for new designs and production applications. This part carries active product status from Cornell Dubilier / Illinois Capacitor, ensuring continued availability and manufacturing consistency. Current inventory of 732 units supports immediate procurement. The part is ROHS3 compliant and carries full electrical characterization including ESR specification at 120 Hz.

Secondary Selection: UVP1E330MED

The UVP1E330MED from Nichicon is electrically and mechanically equivalent to the 336BPS025M and is suitable for direct substitution in existing designs where component replacement is required. However, this part carries obsolete product status, indicating discontinued manufacturing. Selection of this substitute should be limited to maintenance, repair, and rework applications where existing inventory is available. Current stock of 1758 units provides temporary supply continuity. ROHS3 compliance is confirmed.

Substitution Constraints:

• The UVP1E330MED is not recommended for new production designs due to obsolete status.
• Both parts are electrically interchangeable within the specified parameter envelope.
• PCB layout compatibility is confirmed due to identical lead spacing and case dimensions.

Frequently Asked Questions (FAQ)

Q: Can the UVP1E330MED replace the 336BPS025M in an existing circuit?

A: Yes. The UVP1E330MED is electrically and mechanically equivalent. Both parts share identical capacitance (33 µF), voltage rating (25 V), tolerance (±20%), operating temperature range (-40°C to 85°C), and lifetime rating (2000 Hrs @ 85°C). Lead spacing and case diameter are identical, confirming PCB footprint compatibility.

Q: Why is the UVP1E330MED listed as obsolete?

A: Obsolete status indicates that Nichicon has discontinued manufacturing of this part. While existing inventory may be available, future procurement cannot be guaranteed. This designation does not affect the electrical or mechanical performance of units currently in stock.

Q: Are there differences in ripple current specifications between these parts?

A: Yes. The 336BPS025M specifies 125.6 mA ripple current at 50 kHz, while the UVP1E330MED specifies 160 mA at 10 kHz. Both parts meet the 2000-hour lifetime requirement at 85°C, indicating thermal design compatibility. Ripple current differences do not prevent direct substitution in applications where the original part was qualified.

Q: What is the significance of the ESR specification on the 336BPS025M?

A: The ESR (Equivalent Series Resistance) of 10.048 Ohm at 120 Hz is provided for the 336BPS025M but not specified for the UVP1E330MED. ESR affects high-frequency performance and ripple current handling. In audio applications, this parameter influences frequency response characteristics. The absence of ESR data for the substitute does not indicate incompatibility; it reflects differences in manufacturer documentation practices.

Q: Are both parts RoHS compliant?

A: Yes. Both the 336BPS025M and UVP1E330MED are ROHS3 compliant, confirming compliance with restricted substance regulations for electronic components.

Q: Can these parts be used interchangeably in audio applications?

A: Yes. Both parts are rated for audio applications and share identical electrical specifications. The 336BPS025M is specified for audio use, while the UVP1E330MED is designated for general purpose use. The general purpose classification of the substitute does not restrict its use in audio circuits where the electrical parameters are equivalent.
