Part Overview
The EMVE6R3ARA331MHA0G is a 330 µF, 6.3 V aluminum electrolytic capacitor manufactured by Chemi-Con in the Alchip™ MVE series. This surface mount radial can capacitor is rated for 2000 hours at 105°C and operates across the temperature range of -40°C to 105°C. The component is ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) and is classified as Active product status.
Equivalent and substitute parts are necessary when the original component becomes unavailable, when design requirements demand higher voltage ratings or extended operational lifetimes, or when alternative manufacturers must be qualified for supply chain resilience. The substitute parts listed maintain the same 330 µF capacitance and ±20% tolerance while offering variations in voltage rating, thermal performance, and ripple current handling.

Engineering Selection Recommendations
For Direct Voltage-Rated Substitution (Same Manufacturer): The EMVE160ARA331MHA0G provides a voltage upgrade from 6.3 V to 16 V while maintaining identical thermal performance (2000 Hrs @ 105°C) and ripple current capacity (290 mA @ 120 Hz). This part is suitable when circuit design permits higher voltage rating without space constraints. Both parts are ROHS3 compliant and carry identical MSL 1 classification.
For Extended Temperature Range: The EMVY160ARA331MHA0G extends the operating temperature range to -55°C ~ 105°C while maintaining 16 V rating and 2000-hour lifetime. This substitution is appropriate for applications requiring broader thermal operation. The ripple current reduces to 225 mA @ 120 Hz, which must be verified against circuit requirements.
For Automotive Applications with Higher Voltage: The EMZA250ARA331MHA0G and EMZJ250ARA331MHA0G both carry AEC-Q200 automotive qualification at 25 V rating. These parts support extended temperature range (-55°C ~ 105°C) and higher ripple current capacity (300-425 mA @ 120 Hz). The EMZJ250ARA331MHA0G offers superior ripple current handling at 425 mA @ 120 Hz. Height increases to 10.30-10.50 mm; verify PCB layout compatibility.
For Extended Operational Lifetime: Rubycon TRV series parts (10TRV330M8X10.5 and 16TRV330M8X10.5) provide 8000-hour lifetime at 105°C, quadrupling the original 2000-hour rating. These parts maintain -40°C ~ 105°C temperature range and offer higher ripple current (360 mA @ 120 Hz). Height increases to 10.50 mm.
For Automotive Extended Lifetime: The 16TZV330M8X10.5 combines Rubycon manufacturing with AEC-Q200 automotive qualification, 16 V rating, 2000-hour lifetime, and -55°C ~ 105°C temperature range. Ripple current is 360 mA @ 120 Hz.
For Alternative Manufacturer Sourcing: Cornell Dubilier Electronics AFK series (AFK337M10F24T-F at 10 V and AFK337M16F24T-F at 16 V) provide AEC-Q200 qualification, extended temperature range (-55°C ~ 105°C), and superior ripple current (450 mA @ 120 Hz). Surface mount land size increases to 0.327" L x 0.394" W; verify PCB pad compatibility. ESR is specified at 160 mOhm @ 100 kHz.
The Cornell Dubilier 337AXZ025M offers 25 V rating with general-purpose classification and extended temperature range (-55°C ~ 105°C), suitable for non-automotive applications requiring higher voltage margin.
Frequently Asked Questions (FAQ)
Q: Can EMVE6R3ARA331MHA0G be directly replaced with a higher voltage-rated part?
A: Yes, higher voltage-rated parts with identical capacitance (330 µF), tolerance (±20%), and physical dimensions are direct substitutes. The EMVE160ARA331MHA0G (16 V) and EMVY160ARA331MHA0G (16 V, extended temperature) are pin-compatible upgrades. Verify that the circuit design does not depend on the lower 6.3 V rating for voltage-limiting functions.
Q: What is the difference between EMVE160ARA331MHA0G and EMVY160ARA331MHA0G?
A: Both are 330 µF, 16 V Chemi-Con parts with identical 2000-hour lifetime at 105°C. The EMVY160ARA331MHA0G extends the operating temperature range to -55°C (versus -40°C minimum for EMVE160ARA331MHA0G) and includes impedance specification (300 mOhms). The EMVY160ARA331MHA0G ripple current is 225 mA @ 120 Hz compared to 290 mA for EMVE160ARA331MHA0G.
Q: Are Rubycon TRV parts compatible with the original EMVE6R3ARA331MHA0G footprint?
A: The Rubycon TRV series maintains the 0.315" diameter (8.00 mm) and 0.327" x 0.327" land size, but height increases from 10.00 mm to 10.50 mm. Verify PCB clearance above the component before substitution. All other mechanical and electrical parameters are compatible.
Q: What does AEC-Q200 qualification mean for substitution?
A: AEC-Q200 is an automotive industry standard for discrete semiconductors and passive components. Parts carrying this rating (EMZA250ARA331MHA0G, EMZJ250ARA331MHA0G, 16TZV330M8X10.5, AFK337M10F24T-F, AFK337M16F24T-F) have undergone extended reliability testing and are approved for automotive applications. Non-automotive designs may use these parts without restriction.
Q: Can I substitute EMVE6R3ARA331MHA0G with a 25 V rated part?
A: Yes. The EMZA250ARA331MHA0G and EMZJ250ARA331MHA0G both provide 25 V rating with identical 330 µF capacitance. The EMZJ250ARA331MHA0G offers higher ripple current (425 mA @ 120 Hz) and lower impedance (80 mOhm @ 100 kHz). Height increases to 10.30-10.50 mm; verify PCB layout compatibility.
Q: What is the impact of ripple current differences between substitute parts?
A: Ripple current rating determines the maximum AC current the capacitor can handle without exceeding temperature limits. The original EMVE6R3ARA331MHA0G is rated for 290 mA @ 120 Hz. Substitutes with higher ripple current ratings (360-450 mA @ 120 Hz) provide additional margin for high-frequency switching applications. Substitutes with lower ripple current (225 mA for EMVY160ARA331MHA0G) must be verified against actual circuit ripple current demands.
Q: Are Cornell Dubilier AFK parts compatible with the original PCB layout?
A: AFK337M10F24T-F and AFK337M16F24T-F maintain the 0.315" diameter and 10.50 mm height, but the surface mount land size increases to 0.327" L x 0.394" W (compared to 0.327" x 0.327" for the original). Verify that PCB pads can accommodate the wider 0.394" width dimension.
Q: What is the difference between 2000-hour and 8000-hour lifetime ratings?
A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation exceeds tolerance limits. The original EMVE6R3ARA331MHA0G and most substitutes are rated for 2000 hours. Rubycon TRV series parts (10TRV330M8X10.5, 16TRV330M8X10.5) provide 8000-hour lifetime, extending service life by a factor of four under continuous maximum-temperature operation.
Q: Can EMVE6R3ARA331MHA0G be used in circuits requiring -55°C minimum temperature operation?
A: No. The original part operates from -40°C minimum. For -55°C operation, substitute with EMVY160ARA331MHA0G, EMZA250ARA331MHA0G, EMZJ250ARA331MHA0G, 16TZV330M8X10.5, 337AXZ025M, AFK337M10F24T-F, or AFK337M16F24T-F, all of which specify -55°C minimum operating temperature.
Q: What does MSL 1 (Unlimited) mean for component handling?
A: MSL (Moisture Sensitivity Level) 1 indicates the component has unlimited shelf life and requires no special moisture-control handling during storage, transportation, or assembly. All listed substitute parts carry MSL 1 classification, matching the original component's handling requirements.
