EMVE250ARA331MJA0G Equivalent & Substitute Parts

Part Overview

The EMVE250ARA331MJA0G is a 330 µF, 25 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 necessary when the original manufacturer part becomes unavailable, when design requirements demand enhanced performance characteristics such as higher temperature ratings or extended lifetime specifications, or when automotive-grade certifications (AEC-Q200) are required for specific applications.

Voltage Rating: 25 V (exact match or higher acceptable)
Package Type: Radial, Can - SMD (exact match required)
Mounting Type: Surface Mount (exact match required)
Physical Dimensions: 0.394" Dia (10.00mm) with compatible height and land size

Engineering Selection Recommendations

For Direct Substitution (Identical Electrical Performance):

The following parts maintain full electrical and mechanical compatibility with the EMVE250ARA331MJA0G:

EEE-TG1E331UP (Panasonic TG series): Maintains 330 µF / 25 V specifications with AEC-Q200 automotive certification. Height of 0.402" (10.20mm) is within acceptable tolerance. Suitable for applications requiring automotive-grade reliability.
UCX1E331MCL1GS (Nichicon UCX series): Maintains 330 µF / 25 V specifications with extended temperature capability to 135°C. Product status is "Not For New Designs"; use only for legacy system maintenance or repair applications.

For Performance Enhancement (Upgrade Substitutes):

EMHJ250ARA331MJA0G (Chemi-Con Alchip™ MHJ): Upgrade within same manufacturer. Extends operating temperature to 125°C, adds AEC-Q200 certification, and specifies 120 mOhm ESR. Height increases to 0.406" (10.30mm), which remains compatible with standard 10.30mm land size.
25TGV330M10X10.5 (Rubycon TGV series): Extends lifetime to 3000 Hrs @ 125°C with AEC-Q200 certification and 120 mOhm ESR specification. Height of 0.413" (10.50mm) requires verification of available board clearance.
EEE-TC1E331P (Panasonic TC series): Extends lifetime to 3000 Hrs @ 125°C with AEC-Q200 certification and 150 mOhm ESR. Suitable for automotive and high-temperature reflow applications.
EXV337M025A9PAA (KEMET EXV series): Extends lifetime to 5000 Hrs @ 105°C with 120 mOhm ESR and wider operating temperature range (-55°C ~ 105°C). Suitable for extended-life general purpose applications.

For Voltage Upgrade (Higher Voltage Rating):

EMZA350ARA331MJA0G (Chemi-Con Alchip™ MZA): Increases voltage rating to 35 V while maintaining 330 µF capacitance. Includes AEC-Q200 certification and 80 mOhm ESR. Height increases to 0.413" (10.50mm). Use when circuit design requires higher voltage margin or when 35 V rated components are specified.
UCL1V331MNL1GS (Nichicon UCL series): Increases voltage rating to 35 V with 330 µF capacitance. Maintains original height of 0.394" (10.00mm) with superior 60 mOhm ESR. Suitable for space-constrained applications requiring higher voltage rating.

Product Status Considerations:

All recommended substitute parts carry "Active" product status except UCX1E331MCL1GS, which is marked "Not For New Designs." The UCX series part is acceptable only for repair or maintenance of existing systems. For new designs, select from parts with "Active" status.

Frequently Asked Questions (FAQ)

Q: Can I use a 35 V rated capacitor in place of the 25 V EMVE250ARA331MJA0G?

A: Yes. A higher voltage rating is electrically compatible and provides additional safety margin. Parts EMZA350ARA331MJA0G and UCL1V331MNL1GS both provide 330 µF at 35 V. Verify that the increased height (up to 0.413" for EMZA350ARA331MJA0G) does not exceed available board clearance.

Q: What is the difference between "Direct Substitute" and "Upgrade Substitute"?

A: Direct substitutes maintain identical electrical specifications (330 µF, 25 V, 2000 Hrs @ 105°C). Upgrade substitutes enhance one or more performance parameters such as lifetime, temperature rating, or ESR while remaining fully backward compatible. All substitute parts listed maintain the same capacitance, tolerance, voltage, package type, and mounting configuration as the original part.

Q: Does the height difference between 0.394" and 0.413" affect compatibility?

A: Height differences must be verified against available board clearance in your specific application. The original EMVE250ARA331MJA0G is 0.394" (10.00mm) tall. Substitute parts with heights up to 0.413" (10.50mm) are mechanically compatible with the same 10.30mm x 10.30mm land size but require confirmation that no components or board features obstruct the additional 0.019" (0.50mm) of height.

Q: Which substitute part offers the longest lifetime?

A: The 25TRV330M10X10.5 (Rubycon TRV series) provides 8000 Hrs @ 105°C, the longest lifetime among all listed substitutes. The EXV337M025A9PAA (KEMET EXV series) provides 5000 Hrs @ 105°C. Both are suitable for applications requiring extended operational life.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry RoHS3 compliance status, matching the original EMVE250ARA331MJA0G. All parts also maintain MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special moisture protection is required during storage or handling.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive electronics qualification standard. Parts bearing this certification have been tested and qualified for automotive applications. The EMVE250ARA331MJA0G does not carry AEC-Q200 certification. Substitute parts with AEC-Q200 (EMHJ250ARA331MJA0G, EMZA350ARA331MJA0G, EEE-TC1E331P, EEE-TG1E331UP, 25TGV330M10X10.5) are suitable for automotive designs requiring this qualification.

Q: Can I use UCX1E331MCL1GS for new product designs?

A: No. The UCX1E331MCL1GS is marked "Not For New Designs." This designation indicates the part is in end-of-life status. Use this part only for repair or maintenance of existing systems. For new designs, select from parts with "Active" product status.

Q: What is ESR and why does it matter?

A: ESR (Equivalent Series Resistance) is the internal resistance of the capacitor, measured at 100 kHz. Lower ESR values indicate better high-frequency performance and reduced heat generation. The original EMVE250ARA331MJA0G does not specify ESR. Substitute parts with specified ESR values (ranging from 60 mOhm to 300 mOhm) provide measurable performance characteristics. For applications sensitive to ripple current or high-frequency noise, select substitutes with lower ESR values.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for automated assembly. Cut Tape (CT) supplies components on tape cut into smaller lengths. The original EMVE250ARA331MJA0G uses Tape & Reel packaging. Most substitute parts also use Tape & Reel. EMZA350ARA331MJA0G uses Cut Tape & Digi-Reel® packaging; verify compatibility with your assembly equipment before selection.
