Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CGS222U040R2C are identified based on strict electrical and mechanical parameter alignment. The substitution logic operates under the following constraints:

Fixed Parameters (Non-Negotiable):

• Capacitance: 2200 µF (exact match required)
• Package / Case: Radial, Can - Screw Terminals (identical form factor)
• Size / Dimension: 1.375" Dia (34.93mm) (mechanical compatibility)
• Height - Seated (Max): 2.125" (53.98mm) (mounting clearance)
• Mounting Type: Chassis Mount (installation method)
• Operating Temperature Range: -40°C to 85°C (thermal envelope)
• Lifetime @ Temperature: 2000 Hrs @ 85°C (reliability specification)
• Polarization: Polar (electrical polarity requirement)
• RoHS Status: ROHS3 Compliant (regulatory compliance)

Variable Parameter (Substitution Basis):

• Voltage - Rated: Substitutes feature 50 V or 75 V ratings, representing voltage upgrades from the base 40 V specification

Acceptable Variation:

• ESR @ 120Hz: Minor variations (41-44 mOhm) are acceptable within the same product series, reflecting manufacturing tolerances and voltage rating adjustments

All substitute parts maintain identical series designation (CGS), manufacturer (Cornell Dubilier Electronics), and active product status.

Parameter Comparison

Engineering Selection Recommendations

CGS222U040R2C (Base Part): Use this part when circuit design specifies a maximum operating voltage of 40 V. The part is Active status with full RoHS3 compliance and REACH unaffected designation, confirming regulatory suitability for current manufacturing standards.

CGS222U050R2C (50 V Upgrade): Select this substitute when circuit operating voltage reaches 50 V or when design margin requires voltage headroom above 40 V. Electrical performance remains equivalent to the base part with identical ESR and ripple current specifications. Physical dimensions and mounting characteristics are identical, enabling direct mechanical substitution. Active product status and full compliance certifications apply.

CGS222U075R2C (75 V Upgrade): Select this substitute when circuit operating voltage reaches 75 V or when maximum design margin is required. This part exhibits marginally improved ESR performance (41 mOhm versus 44 mOhm) and slightly elevated ripple current capability at both 120 Hz and 10 kHz. Physical dimensions and mounting characteristics remain identical to the base part. Active product status and full compliance certifications apply.

All three parts maintain identical capacitance (2200 µF), thermal lifetime specification (2000 Hrs @ 85°C), operating temperature range (-40°C to 85°C), and chassis mount configuration. Selection between these parts depends solely on the maximum voltage requirement of the target circuit application.

Frequently Asked Questions (FAQ)

Q: Can CGS222U050R2C or CGS222U075R2C be used as direct replacements for CGS222U040R2C?

A: Yes, both substitute parts are direct mechanical and electrical replacements when circuit voltage requirements permit. All three parts share identical capacitance (2200 µF), physical dimensions (1.375" diameter, 2.125" height), screw terminal configuration, and chassis mount design. The substitute parts feature higher voltage ratings, which do not degrade performance in lower-voltage applications.

Q: What is the primary difference between the three parts?

A: The rated voltage differs: CGS222U040R2C operates at 40 V, CGS222U050R2C at 50 V, and CGS222U075R2C at 75 V. All other electrical and mechanical parameters remain constant across the series.

Q: Are there any performance differences between these parts?

A: ESR and ripple current specifications show minor variations. CGS222U040R2C and CGS222U050R2C both exhibit 44 mOhm ESR @ 120Hz, while CGS222U075R2C exhibits 41 mOhm ESR @ 120Hz. Ripple current at 120 Hz is 4.1 A for the 40 V and 50 V parts, and 4.2 A for the 75 V part. These variations reflect manufacturing characteristics within the CGS series and do not indicate functional incompatibility.

Q: Do all three parts meet current regulatory requirements?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and maintain Active product status. Moisture sensitivity level is 1 (Unlimited) for all three parts.

Q: Can I use a higher-voltage part in a circuit designed for a lower voltage?

A: Yes. A 75 V rated capacitor functions correctly in a 40 V circuit. The higher voltage rating provides additional safety margin and does not compromise circuit operation. However, physical space constraints and cost considerations may influence the selection decision.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share identical diameter (1.375" / 34.93mm), maximum seated height (2.125" / 53.98mm), and screw terminal configuration. They are mechanically interchangeable without modification to mounting hardware or PCB layout.

Q: What is the thermal lifetime specification for these capacitors?

A: All three parts are rated for 2000 hours of operation at 85°C. Operating temperature range is -40°C to 85°C for all parts.
