337BPS016M Equivalent & Substitute Parts

Part Overview

The 337BPS016M is a 330 µF, 16 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the BPS series. This radial, through-hole component is designed for audio applications with a rated lifetime of 2000 hours at 85°C and operates across the temperature range of -40°C to 85°C. The part maintains an equivalent series resistance (ESR) of 1.105 Ohm at 120 Hz and supports ripple currents of 375 mA at low frequency and 558.75 mA at high frequency.

The 337BPS016M is currently in active production status. Identifying equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and maintain component availability across manufacturing cycles.

Substitute Part Grouping Explanation

Substitution eligibility for the 337BPS016M is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Bi-Polar (exact match required)
• Lead Spacing: 0.197" (5.00 mm) (exact match required)
• Case Diameter: 0.394" (10.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Lifetime @ Temperature: 2000 Hrs @ 85°C (exact match required)

The substitute part UVP1C331MPD manufactured by Nichicon meets all mandatory matching parameters and qualifies as a direct electrical and mechanical equivalent to the 337BPS016M.

Engineering Selection Recommendations

337BPS016M (Cornell Dubilier / Illinois Capacitor)

The 337BPS016M maintains active product status and is recommended for new designs requiring long-term component availability and manufacturer support. This part is ROHS3 compliant and REACH unaffected, providing regulatory compliance across multiple jurisdictions. The specified ESR of 1.105 Ohm at 120 Hz and ripple current ratings of 375 mA at 120 Hz and 558.75 mA at 50 kHz support audio applications with defined performance characteristics.

UVP1C331MPD (Nichicon)

The UVP1C331MPD is classified as "Not For New Designs" and carries REACH affected status. This part is suitable for replacement or repair applications where existing inventory is available. The substitute maintains electrical equivalence across all critical parameters and supports the same ripple current at 120 Hz (375 mA). The seated height of 0.689" (17.50 mm) is 0.020" lower than the main part, which may provide minor PCB layout advantages in space-constrained applications. Inventory availability of 2687 pieces supports supply chain continuity for ongoing production or field service requirements.

Frequently Asked Questions (FAQ)

Q: Can UVP1C331MPD be used as a direct replacement for 337BPS016M in new designs?

A: UVP1C331MPD meets all electrical and mechanical equivalence criteria. However, the part is designated "Not For New Designs" by the manufacturer. New designs should prioritize the 337BPS016M, which maintains active product status and full manufacturer support.

Q: What are the physical differences between these parts?

A: Both parts share identical case diameter (0.394" / 10.00 mm) and lead spacing (0.197" / 5.00 mm). The seated height differs by 0.020" (0.50 mm), with UVP1C331MPD measuring 0.689" (17.50 mm) compared to 337BPS016M at 0.709" (18.00 mm). This difference is within typical PCB layout tolerances for through-hole components.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant. The 337BPS016M is REACH unaffected, while UVP1C331MPD is REACH affected. Applications subject to REACH regulations should confirm compliance requirements with the end-use jurisdiction.

Q: What is the significance of the ESR specification?

A: The 337BPS016M specifies ESR of 1.105 Ohm at 120 Hz. UVP1C331MPD does not provide ESR data in the available specifications. For audio applications where ESR performance is critical, the 337BPS016M provides documented performance characteristics.

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

A: Both parts are rated for audio applications and maintain identical capacitance, voltage, tolerance, and ripple current specifications at 120 Hz. The 337BPS016M provides documented ESR performance, while UVP1C331MPD specifications do not include ESR data. Circuit performance depends on specific audio frequency response requirements.

Q: What is the difference in ripple current ratings at high frequency?

A: The 337BPS016M supports 558.75 mA at 50 kHz, while UVP1C331MPD supports 562.5 mA at 10 kHz. These specifications reflect different measurement frequencies and do not indicate direct equivalence at all frequency ranges. Application-specific ripple current requirements should be evaluated against the frequency of operation.
