Substitute Part Grouping Explanation

Substitution of the CGS332T350X5L is determined by strict equivalence in the following parameters:

Fixed Parameters (Must Match):

• Capacitance: 3300 µF
• Package / Case: Radial, Can - Screw Terminals
• Mounting Type: Chassis Mount
• Physical Dimensions: 3.000" Dia (76.20 mm), 5.625" Height (142.88 mm)
• Polarization: Polar
• Tolerance: -10%, +50%
• Operating Temperature Range: -40°C ~ 85°C
• Lifetime @ Temperature: 2000 Hrs @ 85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Allowable Substitution Criteria):

• Voltage - Rated: Higher voltage ratings are acceptable for applications requiring increased voltage margin
• ESR (Equivalent Series Resistance): Lower ESR values indicate improved performance characteristics
• Ripple Current Capacity: Higher ripple current ratings provide increased operational headroom

The CGS332T450X5L qualifies as a direct substitute based on identical mechanical packaging, identical capacitance value, and identical thermal and compliance specifications, with the distinction of an elevated voltage rating and improved electrical performance metrics.

Parameter Comparison

Engineering Selection Recommendations

Both the CGS332T350X5L and CGS332T450X5L maintain Active product status with full ROHS3 compliance and REACH unaffected designation, ensuring regulatory compliance for current and future applications. Both components are manufactured by Cornell Dubilier Electronics within the CGS series, confirming consistent quality and reliability standards.

The CGS332T450X5L provides enhanced electrical performance through reduced ESR (31 mOhm versus 44 mOhm) and increased ripple current capacity at both low frequency (11.4 A versus 9.5 A @ 120 Hz) and high frequency (17.1 A versus 14.25 A @ 10 kHz). The elevated voltage rating of 450 V accommodates applications requiring higher voltage margins while maintaining identical mechanical fit and thermal characteristics.

Selection between these parts depends on circuit voltage requirements and thermal management considerations. The CGS332T350X5L is appropriate for 350 V rated applications. The CGS332T450X5L is suitable for circuits operating at or below 350 V where improved ESR performance or increased ripple current capacity is required, or for circuits designed for 450 V operation.

Frequently Asked Questions (FAQ)

Q: Can the CGS332T450X5L be used in place of the CGS332T350X5L?

A: Yes. The CGS332T450X5L is a direct mechanical and electrical substitute. Both components share identical capacitance (3300 µF), package configuration (Radial, Can - Screw Terminals), physical dimensions (3.000" Dia × 5.625" Height), operating temperature range (-40°C ~ 85°C), and thermal lifetime (2000 Hrs @ 85°C). The substitute part features a higher voltage rating (450 V) and improved electrical characteristics (lower ESR and higher ripple current capacity).

Q: What are the physical compatibility requirements?

A: Both parts are identical in mechanical specification: 3.000" diameter can, 5.625" maximum seated height, chassis mount configuration with screw terminals. No modifications to mounting hardware, PCB layout, or mechanical enclosure are required for substitution.

Q: How does the voltage rating difference affect circuit operation?

A: The CGS332T450X5L operates at a higher voltage rating (450 V) compared to the CGS332T350X5L (350 V). In circuits operating at or below 350 V, the higher-rated substitute provides additional voltage margin and safety headroom. The substitute is not suitable for applications where the circuit voltage exceeds 350 V unless the circuit design accommodates the higher rating.

Q: What is the significance of the ESR difference?

A: The CGS332T450X5L exhibits lower equivalent series resistance (31 mOhm @ 120 Hz) compared to the CGS332T350X5L (44 mOhm @ 120 Hz). Lower ESR reduces heat generation during ripple current operation and improves transient response characteristics. This performance improvement is inherent to the higher voltage rating design.

Q: Are there ripple current implications for substitution?

A: The CGS332T450X5L supports higher ripple current capacity at both low frequency (11.4 A @ 120 Hz versus 9.5 A) and high frequency (17.1 A @ 10 kHz versus 14.25 A). Applications with ripple current demands exceeding the CGS332T350X5L specification benefit from the substitute's increased capacity. Applications within the original part's ripple current rating operate within the substitute's capability margin.

Q: Do compliance and regulatory certifications differ between these parts?

A: No. Both the CGS332T350X5L and CGS332T450X5L maintain identical compliance status: ROHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 1 (Unlimited). No additional regulatory review is required for substitution.

Q: What is the inventory status for these parts?

A: The CGS332T350X5L has 1132 units in stock. The CGS332T450X5L has 1012 units in stock. Both are available as new original components.
