CGS103U016R3C Equivalent & Substitute Parts

Part Overview

The CGS103U016R3C is a 10000 µF, 16 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in the CGS series. This radial, can-type capacitor with screw terminals is designed for general-purpose applications and is currently active in the product lineup. The part features a 24 mOhm equivalent series resistance at 120 Hz, 2000-hour lifetime rating at 85°C, and ROHS3 compliance. Finding equivalent or substitute parts becomes necessary when managing inventory across multiple voltage ratings, optimizing for specific electrical parameters, or addressing sourcing constraints while maintaining design compatibility.

Substitute Part Grouping Explanation

Substitute parts for the CGS103U016R3C are grouped based on electrical and mechanical compatibility within the CGS series. The substitution logic follows these criteria:

Upgrade Substitutes (Higher Voltage Rating): CGS103U025R3C and CGS103U075R3C maintain identical capacitance (10000 µF) and mechanical dimensions (1.375" diameter, 3.125" height) as the main part, with higher voltage ratings of 25 V and 75 V respectively. These can replace the 16 V rated part in applications requiring additional voltage margin, provided circuit design allows the higher voltage rating. The ESR specifications remain consistent or acceptable for the upgrade path (24 mOhm for 25 V; 29 mOhm for 75 V).

Similar Substitute (Same Voltage, Different ESR): CGS103U016R2C maintains identical voltage rating (16 V) and capacitance (10000 µF) with the same mechanical footprint diameter (1.375"), but differs in physical height (2.125" versus 3.125") and ESR performance (33 mOhm versus 24 mOhm). This part represents a more compact alternative where space constraints permit, though with reduced ripple current handling capability.

All substitutes maintain ROHS3 compliance, identical tolerance specifications (-10%, +75%), operating temperature range (-40°C ~ 85°C), and chassis mount configuration with screw terminals.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring continued supply chain viability and regulatory adherence. The choice between substitutes depends on specific application constraints:

CGS103U025R3C provides a direct mechanical and electrical upgrade with increased voltage rating while preserving the original ESR specification and board height. This substitution is appropriate for applications where voltage headroom is beneficial and the PCB layout accommodates the higher-rated component.

CGS103U075R3C offers the highest voltage rating for maximum design margin but introduces a 5 mOhm increase in ESR and slightly reduced ripple current capacity. Selection should account for the electrical performance trade-offs in ripple current applications.

CGS103U016R2C accommodates space-constrained designs with a 1-inch reduction in axial height while maintaining the rated voltage and capacitance. The 9 mOhm ESR increase and proportionally reduced ripple current handling require verification against application ripple current demands.

Frequently Asked Questions (FAQ)

Q: Can CGS103U025R3C replace CGS103U016R3C directly on the PCB? A: Yes. CGS103U025R3C shares identical mechanical dimensions (1.375" diameter, 3.125" height), mounting configuration (chassis mount with screw terminals), and mounting footprint. The higher voltage rating (25 V versus 16 V) and matching ESR (24 mOhm) maintain electrical performance parity.

Q: What is the key difference between CGS103U016R3C and CGS103U016R2C? A: Both parts share identical capacitance (10000 µF) and voltage rating (16 V), but differ in physical height (3.125" versus 2.125") and ESR (24 mOhm versus 33 mOhm). CGS103U016R2C is a more compact alternative for space-limited applications, with a trade-off in ripple current capacity and ESR performance.

Q: Is CGS103U075R3C suitable for all applications designed for the CGS103U016R3C? A: CGS103U075R3C is electrically compatible in terms of mechanical fit and mounting, but features a higher voltage rating (75 V), slightly increased ESR (29 mOhm), and reduced ripple current capacity. Compatibility depends on whether the application can accommodate these electrical parameter changes without performance degradation.

Q: Do all substitute parts maintain the same operating temperature range? A: Yes. All substitute parts operate across the identical range of -40°C to 85°C with matching 2000-hour lifetime ratings at 85°C.

Q: Are all these parts ROHS3 compliant? A: Yes. CGS103U016R3C, CGS103U025R3C, CGS103U075R3C, and CGS103U016R2C are all ROHS3 compliant and REACH unaffected.
