Engineering Selection Recommendations

107SML6R3M (Cornell Dubilier): Active product status with complete electrical specifications. ROHS3 compliant and REACH unaffected. Suitable for new designs and ongoing production runs requiring documented ESR performance.

UWR0J101MCL1GB (Nichicon): Obsolete product status. While electrically equivalent and mechanically interchangeable, the obsolete status indicates discontinued production. ROHS3 compliant and REACH unaffected. Available from inventory stock with high unit availability (72,858 pcs). Selection appropriate only where existing stock utilization is prioritized or supply continuity for legacy production is required.

Both parts meet identical dimensional, electrical, and compliance requirements for direct circuit substitution. Selection between them should be based on product lifecycle status and supply chain availability requirements.

Frequently Asked Questions (FAQ)

Q: Can the Nichicon UWR0J101MCL1GB directly replace the Cornell Dubilier 107SML6R3M? A: Yes. Both parts share identical capacitance (100 µF), voltage rating (6.3 V), tolerance (±20%), physical dimensions (5.00 mm diameter × 5.50 mm height), operating temperature range (-40°C to 85°C), and mounting type (surface mount). The parts are footprint-compatible and electrically equivalent for all critical parameters.

Q: What is the significance of the product status difference? A: The Cornell Dubilier 107SML6R3M is in active production, indicating ongoing availability. The Nichicon UWR0J101MCL1GB is obsolete, meaning production has been discontinued. Obsolete status does not affect electrical performance but indicates the part is no longer manufactured. Selection should account for long-term supply requirements.

Q: Are there differences in ripple current handling? A: The Cornell Dubilier part specifies ripple current values of 54 mA @ 120 Hz and 81 mA @ 100 kHz. The Nichicon part specifies 47 mA @ 120 Hz and 70.5 mA @ 10 kHz. These differences represent performance variations but do not prevent substitution in general-purpose applications. Circuit designers should verify ripple current requirements against application specifications.

Q: What is the ESR difference between these parts? A: The Cornell Dubilier 107SML6R3M specifies ESR of 4.642 Ω @ 120 Hz. The Nichicon UWR0J101MCL1GB does not provide ESR specification in the available data. ESR affects high-frequency performance and power dissipation. In applications sensitive to ESR, the Cornell Dubilier specification should be verified against design requirements.

Q: Are both parts RoHS compliant? A: Yes. Both the Cornell Dubilier 107SML6R3M and Nichicon UWR0J101MCL1GB are ROHS3 compliant and REACH unaffected, suitable for regulated manufacturing environments.

Q: What packaging formats are available? A: The Cornell Dubilier 107SML6R3M is available in standard packaging. The Nichicon UWR0J101MCL1GB is supplied in Tape & Reel (TR) format, typical for high-volume surface mount assembly operations.
