Engineering Selection Recommendations

For Direct Replacement (Identical Performance): Select EMVE350ARA331MJA0G from Chemi-Con. This part maintains the same physical footprint (0.394" x 0.394"), identical capacitance and voltage specifications, and equivalent 2000-hour lifetime at 85°C. The part is Active status and available in Tape & Reel packaging. This substitution requires no design modification.

For Extended Temperature Operation (-40°C to 105°C): Select EMLA350ARA331MJA0G, EMVE350ARA331MJA0G, EMVY350ARA331MJA0G, or EEE-FK1V331P. All maintain 330 µF / 35 V specifications with extended upper temperature limit to 105°C. EMVY350ARA331MJA0G and EEE-FK1V331P additionally extend the lower temperature limit to -55°C. All are Active status parts.

For Automotive Applications (AEC-Q200 Compliance): Select EMZA350ARA331MJA0G, EMZA350GRA331MJA0G, AFK337M35G24T-F, or EEE-FK1V331P. These parts carry AEC-Q200 automotive qualification, operate across -55°C to 105°C, and provide 2000-hour lifetime at 105°C. EMZA series parts are available from Chemi-Con with extensive inventory (1,000,100 units). AFK337M35G24T-F from Cornell Dubilier and EEE-FK1V331P from Panasonic are also qualified alternatives.

For General Purpose Applications with Active Status: KEMET EDK337M035A9PAA is an Active status alternative with identical thermal performance to the original part (2000 Hrs @ 85°C, -40°C to 85°C). This part is suitable for non-automotive general purpose applications.

Parts to Avoid for New Designs: EEE-1VA331P is marked "Not For New Designs" and should not be selected for new applications. EEE-1VA331UAP has reduced lifetime (1000 Hrs @ 85°C) compared to the original specification and is suitable only for applications with lower thermal stress.

Frequently Asked Questions (FAQ)

Q: Can EMVE350ARA331MJA0G be used as a direct replacement for EMVA350ADA331MJA0G?

A: Yes. Both parts share identical electrical specifications (330 µF, 35 V, ±20% tolerance), physical dimensions (0.394" diameter x 0.394" height), and surface mount land size (0.406" x 0.406"). The EMVE350ARA331MJA0G is Active status and available in Tape & Reel packaging. The only differences are the series designation (MVE vs. MVA) and packaging format (TR vs. CT). No design modification is required.

Q: What is the difference between EMLA350ARA331MJA0G and EMVE350ARA331MJA0G?

A: Both parts are 330 µF / 35 V Chemi-Con capacitors with extended temperature operation to 105°C. The EMLA350ARA331MJA0G (Alchip™ MLA series) provides 3000-hour lifetime at 105°C and has a maximum seated height of 0.406" (10.30mm). The EMVE350ARA331MJA0G (Alchip™ MVE series) provides 2000-hour lifetime at 105°C with a maximum seated height of 0.394" (10.00mm). Select EMLA for applications requiring extended thermal endurance; select EMVE for space-constrained designs.

Q: Are automotive-grade parts (AEC-Q200) compatible with general purpose applications?

A: Yes. Automotive-qualified parts such as EMZA350ARA331MJA0G, AFK337M35G24T-F, and EEE-FK1V331P meet or exceed all general purpose application requirements. These parts provide enhanced reliability through automotive qualification and extended temperature operation (-55°C to 105°C). They are suitable for any application requiring 330 µF / 35 V capacitance.

Q: What is the impact of height differences between substitute parts?

A: Physical height differences affect PCB layout and clearance. The original EMVA350ADA331MJA0G has a maximum seated height of 0.394" (10.00mm). Substitute parts with heights of 0.402" (10.20mm), 0.406" (10.30mm), or 0.413" (10.50mm) require verification of available vertical clearance on the PCB. If clearance is limited, select EMVE350ARA331MJA0G or EMVY350ARA331MJA0G, which maintain the 0.394" (10.00mm) height specification.

Q: Can I use EEE-1VA331UAP as a substitute?

A: EEE-1VA331UAP is electrically compatible (330 µF, 35 V, ±20%) and physically compatible (0.394" diameter, 0.402" height). However, this part has a reduced lifetime specification of 1000 hours at 85°C compared to the original 2000 hours at 85°C. Use this part only in applications with lower thermal stress or shorter operational life requirements. For standard applications, select parts with 2000-hour or greater lifetime ratings.

Q: What packaging formats are available for substitutes?

A: Substitute parts are available in Cut Tape (CT), Tape & Reel (TR), and Digi-Reel® formats. EMVA350ADA331MJA0G is supplied in Cut Tape. Direct substitutes EMVE350ARA331MJA0G, EMVY350ARA331MJA0G, and most alternatives are supplied in Tape & Reel. EMZA350ARA331MJA0G is available in both Cut Tape and Digi-Reel® formats. Verify packaging compatibility with your procurement and assembly processes.

Q: Is the surface mount land size identical across all substitutes?

A: The standard surface mount land size is 0.406" L x 0.406" W (10.30mm x 10.30mm) for all substitutes except AFK337M35G24T-F, which has a land size of 0.406" L x 0.473" W (10.30mm x 12.00mm). This difference reflects a wider pad layout on the AFK part. Verify PCB layout compatibility before selecting AFK337M35G24T-F.

Q: Which substitute offers the best inventory availability?

A: EMZA350ARA331MJA0G from Chemi-Con has the highest inventory level at 1,000,100 units. EEE-FK1V331P from Panasonic has 18,597 units in stock. Both parts are Active status with extended temperature operation and automotive qualification. For immediate availability with general purpose specifications, EDK337M035A9PAA from KEMET has 778 units available.
