Key Parameters

Substitute Part Grouping Explanation

Substitution of the CGS183U075V4C is determined by the following criteria:

Capacitance Match: The substitute part must maintain the same 18000 µF capacitance value to ensure equivalent energy storage and circuit performance.

Voltage Rating Compatibility: The substitute part voltage rating must be equal to or greater than the original 75 V rating. A higher voltage rating (such as 100 V) provides additional safety margin and is electrically compatible in applications designed for 75 V operation.

Package and Mounting Compatibility: The substitute must use identical Radial, Can - Screw Terminals packaging and Chassis Mount configuration to ensure mechanical fit and terminal compatibility.

Physical Dimensions: The substitute must match the original 2.000" diameter and 4.125" maximum seated height to fit within the same mechanical envelope.

Series Consistency: Both parts belong to the CGS series from Cornell Dubilier Electronics, ensuring design and performance consistency.

Electrical Performance Parameters: ESR, ripple current ratings, operating temperature range, and lifetime specifications must be suitable for the intended application, though these may vary within acceptable engineering tolerances when voltage rating increases.

Engineering Selection Recommendations

CGS183U100V4C as Substitute:

The CGS183U100V4C qualifies as a direct substitute for the CGS183U075V4C based on identical capacitance (18000 µF), matching package configuration (Radial, Can - Screw Terminals), identical physical dimensions, and compatible mounting type (Chassis Mount).

Both parts are Active products from Cornell Dubilier Electronics, ensuring current availability and manufacturing support. Both achieve ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements for equivalent applications.

The substitute part carries a higher voltage rating (100 V versus 75 V), which provides increased voltage margin in circuits operating at or below 75 V. This characteristic makes the CGS183U100V4C suitable for applications where the original 75 V rating is specified, as the higher rating does not degrade performance in lower-voltage circuits.

The substitute exhibits increased ESR (18 mOhm versus 9 mOhm at 120 Hz) and reduced ripple current ratings (10.5 A at 120 Hz and 13.65 A at 10 kHz versus 14.5 A and 18.85 A respectively). These differences reflect the higher voltage design and must be evaluated against specific circuit ripple current requirements.

Both parts maintain identical operating temperature range (-40°C to 85°C), lifetime specification (2000 Hrs @ 85°C), and tolerance (-10%, +75%), ensuring thermal and temporal performance equivalence.

Frequently Asked Questions (FAQ)

Q: Can CGS183U100V4C replace CGS183U075V4C in all applications?

A: The CGS183U100V4C is electrically compatible in circuits designed for 75 V operation due to its higher 100 V rating. However, the increased ESR and reduced ripple current ratings must be verified against specific circuit requirements. Applications with high ripple current demands may require evaluation of the lower ripple current specifications of the substitute.

Q: What is the primary difference between these two parts?

A: The primary difference is the voltage rating: CGS183U075V4C is rated 75 V, while CGS183U100V4C is rated 100 V. This results in secondary differences in ESR and ripple current performance. Capacitance, physical dimensions, package type, and mounting configuration remain identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical dimensions: 2.000" diameter (50.80mm) and 4.125" maximum seated height (104.78mm). Both use Radial, Can - Screw Terminals packaging and Chassis Mount configuration, ensuring mechanical interchangeability.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both CGS183U075V4C and CGS183U100V4C are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Both are classified under ECCN EAR99 and HTSUS 8532.22.0055.

Q: What should I consider when selecting between these parts?

A: Selection depends on circuit voltage requirements and ripple current specifications. If the circuit operates at 75 V with ripple current demands exceeding 10.5 A at 120 Hz or 13.65 A at 10 kHz, the original CGS183U075V4C is required. If ripple current demands are within the substitute's ratings, the CGS183U100V4C provides higher voltage margin and is suitable for replacement.

Q: Are both parts currently available?

A: Yes. Both parts are Active products with current inventory: CGS183U075V4C has 1045 units in stock, and CGS183U100V4C has 1053 units in stock.
