Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CGS103U016R2C is determined by strict adherence to the following electrical and mechanical parameters:

Electrical Equivalence Requirements:

• Capacitance: 10000 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Lifetime: 2000 Hrs @ 85°C (exact match or better required)
• Tolerance: -10%, +75% (exact match required)

Mechanical Compatibility Requirements:

• Package Type: Radial, Can - Screw Terminals (exact match required)
• Diameter: 1.375" (34.93mm) (exact match required)
• Mounting: Chassis Mount (exact match required)
• Polarization: Polar (exact match required)

Performance Parameters (Optimization Criteria):

• ESR @ 120Hz: Lower values indicate improved performance
• Ripple Current @ 120 Hz and 10 kHz: Higher values provide operational margin

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (required)
• REACH Status: REACH Unaffected (required)

The substitute part CGS103U016R3C meets all electrical and mechanical equivalence requirements. The primary difference is an improved ESR specification (24 mOhm vs. 33 mOhm) and enhanced ripple current ratings, with a height increase to 3.125" (79.38mm) that must be verified against application clearance constraints.

Parameter Comparison

Engineering Selection Recommendations

CGS103U016R3C as Direct Substitute:

The CGS103U016R3C is electrically and mechanically equivalent to the CGS103U016R2C for applications where the increased height of 3.125" (79.38mm) versus 2.125" (53.98mm) does not violate design constraints. Both parts are Active products from the same manufacturer and series, ensuring consistent supply chain reliability and manufacturing standards.

The CGS103U016R3C provides performance advantages through reduced ESR (24 mOhm vs. 33 mOhm) and increased ripple current capacity at both low frequency (6.4 A vs. 4.7 A @ 120 Hz) and high frequency (8.32 A vs. 6.11 A @ 10 kHz). These improvements result in lower heat dissipation and enhanced operational margin under ripple current stress.

Both parts maintain identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and equivalent ECCN/HTSUS classifications. Selection between these parts depends solely on available vertical clearance in the application enclosure.

Frequently Asked Questions (FAQ)

Q: Can CGS103U016R3C replace CGS103U016R2C in any application?

A: CGS103U016R3C is electrically and mechanically equivalent with improved performance characteristics. However, the height difference (3.125" vs. 2.125") must be verified against application clearance constraints. If vertical space is limited, CGS103U016R3C may not fit.

Q: What is the significance of the ESR difference between these parts?

A: ESR (Equivalent Series Resistance) of 24 mOhm in CGS103U016R3C versus 33 mOhm in CGS103U016R2C indicates lower internal resistance. This results in reduced heat generation during ripple current operation and improved frequency response characteristics, particularly beneficial in high-frequency switching applications.

Q: Are the ripple current ratings interchangeable?

A: No. The ripple current ratings define the maximum AC current the capacitor can safely handle without exceeding temperature limits. CGS103U016R3C supports higher ripple currents (6.4 A @ 120 Hz and 8.32 A @ 10 kHz) compared to CGS103U016R2C (4.7 A @ 120 Hz and 6.11 A @ 10 kHz). Applications requiring higher ripple current benefit from CGS103U016R3C.

Q: Do both parts have identical screw terminal compatibility?

A: Yes. Both CGS103U016R2C and CGS103U016R3C use identical Radial, Can - Screw Terminals package configuration. Screw terminal pitch and connector specifications are equivalent, ensuring identical installation procedures.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 Compliant and REACH Unaffected. They share identical ECCN (EAR99) and HTSUS (8532.22.0040) classifications, ensuring equivalent regulatory and export compliance status.

Q: Is the capacitance tolerance identical between both parts?

A: Yes. Both CGS103U016R2C and CGS103U016R3C maintain -10%, +75% capacitance tolerance, ensuring equivalent electrical performance within specified limits.

Q: Can these parts be used in series or parallel configurations?

A: Both parts are polar aluminum electrolytic capacitors and must be connected with correct polarity. Series or parallel configurations require careful consideration of voltage distribution and current sharing, independent of the specific part selected.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have MSL (Moisture Sensitivity Level) of 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special desiccant or humidity control requirements.
