EMVE350ARA331MJA0G Equivalent & Substitute Parts

Part Overview

The EMVE350ARA331MJA0G is a 330 µF, 35 V aluminum electrolytic capacitor manufactured by Chemi-Con in the Alchip™ MVE series. This surface mount radial can capacitor is designed for general purpose applications with a rated lifetime of 2000 hours at 105°C and an operating temperature range of -40°C to 105°C. The component is RoHS3 compliant and carries MSL Level 1 (unlimited moisture sensitivity).

Substitute parts are identified when equivalent electrical specifications (capacitance, voltage rating, tolerance, and lifetime) are maintained across alternative manufacturers and series, with consideration for mechanical compatibility and enhanced performance characteristics where applicable.

Frequently Asked Questions (FAQ)

Q: Can I substitute EMVE350ARA331MJA0G with any of the listed parts without PCB redesign?

A: Direct substitution is possible for parts maintaining the 10.00 mm height (EMVE350ARA331MJA0G and UCL1V331MNL1GS). Parts with 10.50 mm height require verification of available PCB clearance above the component. All parts share identical 0.406" L x 0.406" W (10.30 mm x 10.30 mm) land pattern footprint.

Q: What is the difference between the Chemi-Con MVE and MZA series?

A: The EMZA350ARA331MJA0G (MZA series) provides AEC-Q200 automotive qualification, extended operating temperature range (-55°C to 105°C), and specified impedance (80 mOhms). The EMVE350ARA331MJA0G (MVE series) is general purpose with narrower temperature range (-40°C to 105°C). Both maintain 330 µF, 35 V, ±20% tolerance, and 2000-hour lifetime specifications.

Q: Which substitute offers the best ripple current performance?

A: The AFK337M35G24T-F (Cornell Dubilier) and EEE-FK1V331P (Panasonic) both provide 637.5 mA @ 120 Hz and 850 mA @ 100 kHz ripple current capacity, representing the highest performance among listed substitutes. The UCL1V331MNL1GS (Nichicon) offers 595 mA @ 120 Hz and 1.19 A @ 100 kHz.

Q: Are all substitutes RoHS3 compliant?

A: Yes, all listed substitute parts are RoHS3 compliant. All carry MSL Level 1 (unlimited moisture sensitivity) classification.

Q: What is the advantage of AEC-Q200 rated parts?

A: AEC-Q200 certification indicates the part meets automotive industry reliability and qualification standards. Parts with this rating (EMZA350ARA331MJA0G, AFK337M35G24T-F, EEE-FK1V331P, EEE-FK1V331AP, 35JZV330M10X10.5, 35TKV330M10X10.5, 35TLV330M10X10.5, 35TZV330M10X10.5) are suitable for automotive applications and high-reliability environments.

Q: Which substitute has the lowest impedance?

A: The UCL1V331MNL1GS (Nichicon) and 35TKV330M10X10.5 (Rubycon) both provide 60 mOhms impedance, the lowest among listed substitutes. Lower impedance reduces voltage ripple and improves transient response in power supply applications.

Q: Can I use the 35TLV330M10X10.5 for applications requiring extended component lifetime?

A: Yes, the 35TLV330M10X10.5 (Rubycon TLV series) provides 5000-hour lifetime at 105°C, compared to 2000 hours for the primary part and most substitutes. This extended lifetime is suitable for long-service-life applications with AEC-Q200 automotive qualification.

Q: What packaging options are available?

A: Tape & Reel (TR) packaging is standard for most substitutes. Cut Tape (CT) & Digi-Reel® packaging is available for EMZA350ARA331MJA0G, 35TKV330M10X10.5, and 35TZV330M10X10.5, offering alternative handling and dispensing options for high-volume production.

Q: Is the primary part EMVE350ARA331MJA0G still in active production?

A: Yes, the EMVE350ARA331MJA0G is listed as Active product status with 726 pcs in stock. However, substitute parts with extended temperature range and automotive certifications offer enhanced performance characteristics for new designs.
