ECE-V1VA331P Equivalent & Substitute Parts

Part Overview

The ECE-V1VA331P is a 330 µF, 35 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Panasonic Electronic Components. This part operates across -40°C to 85°C with a rated lifetime of 2000 hours at 85°C and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active product lines are necessary for new designs and ongoing production requirements. Substitute parts maintain the core electrical specifications while offering improved reliability, extended temperature ranges, and enhanced compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria applied strictly to the provided parameters:

Primary Substitution Criteria:

Capacitance: 330 µF (exact match required)
Voltage Rating: 35 V minimum (equal or higher acceptable)
Tolerance: ±20% (exact match)
Polarization: Polar (exact match)
Package / Case: Radial, Can - SMD (exact match)
Mounting Type: Surface Mount (exact match)
Physical Dimensions: 0.394" Dia (10.00mm) (exact match for diameter)
Surface Mount Land Size: 0.406" L x 0.406" W (10.30mm x 10.30mm) (exact match)

Secondary Considerations:

Operating Temperature Range: Extended ranges (-55°C ~ 105°C) are acceptable as they encompass the original -40°C ~ 85°C
Lifetime @ Temperature: Extended lifetimes at higher temperatures provide improved reliability
Ripple Current: Equal or higher values maintain or exceed performance
RoHS Compliance: Active parts with ROHS3 compliance are preferred over non-compliant obsolete parts
Product Status: Active parts are preferred over "Not For New Designs" or obsolete classifications

Voltage Rating Consideration: Parts rated at 50 V (EEE-FT1H331AP, EEE-FT1H331GP) exceed the 35 V requirement and are electrically compatible. These represent upgrades in voltage margin and are suitable for direct substitution in applications where the 35 V rating is not a space or cost constraint.

Engineering Selection Recommendations

Tier 1 - Direct Replacement (Preferred for New Designs):

EEE-FP1V331AP is the optimal substitute. It maintains the original 35 V rating and 330 µF capacitance with identical land size (0.406" L x 0.406" W) and original height (0.402"), ensuring drop-in compatibility. The part is active, ROHS3 compliant, and rated for 2000 hours at 105°C with extended operating temperature range (-55°C ~ 105°C). This part provides superior reliability over the obsolete ECE-V1VA331P while maintaining mechanical compatibility.

Tier 2 - Compatible Substitutes (Active Status, Extended Temperature):

EEE-FK1V331P and EEE-FK1V331AP are active Panasonic parts with identical electrical specifications (330 µF, 35 V, ±20%). Both feature ROHS3 compliance and extended operating temperature (-55°C ~ 105°C). Height increases to 0.413" (10.50mm), requiring PCB layout verification. EEE-FK1V331GP extends lifetime to 5000 hours at 105°C for applications requiring enhanced reliability.

Tier 3 - Voltage-Upgraded Substitutes:

EEE-FT1H331AP and EEE-FT1H331GP provide 50 V rating with 330 µF capacitance. These are suitable where voltage margin is acceptable and space permits the 0.413" height. EEE-FT1H331GP offers 5000-hour lifetime at 105°C. Both are active and ROHS3 compliant.

Tier 4 - Alternative Manufacturer:

AFK337M35G24T-F and AFK337M35G24VT-F (Cornell Dubilier) provide equivalent 330 µF, 35 V specifications with ROHS3 compliance and 2000-hour lifetime at 105°C. Land size is 0.406" L x 0.473" W, requiring PCB footprint adjustment. Heights are 0.413" and 0.425" respectively.

Tier 5 - Reduced Reliability:

EEE-1VA331UAP is active and ROHS3 compliant but rated for only 1000 hours at 85°C, providing lower reliability than the original 2000-hour specification. Use only where lifetime requirements are reduced.

Frequently Asked Questions (FAQ)

Q: Can EEE-FP1V331AP directly replace ECE-V1VA331P without PCB modification?

A: Yes. EEE-FP1V331AP maintains identical capacitance (330 µF), voltage (35 V), tolerance (±20%), land size (0.406" L x 0.406" W), and height (0.402"). It is a mechanical and electrical drop-in replacement.

Q: Why do some substitutes have 50 V rating instead of 35 V?

A: EEE-FT1H331AP and EEE-FT1H331GP are rated at 50 V, exceeding the original 35 V requirement. Higher voltage ratings provide additional safety margin and are electrically compatible. Use these only if PCB layout accommodates the increased height (0.413").

Q: What is the impact of height differences (0.402" vs 0.413" vs 0.425")?

A: Height differences require PCB layout verification. Parts with 0.413" or 0.425" height may contact adjacent components or violate clearance requirements. Confirm available vertical space before substitution. EEE-FP1V331AP maintains the original 0.402" height.

Q: Are Cornell Dubilier parts (AFK series) compatible with Panasonic footprints?

A: AFK337M35G24T-F and AFK337M35G24VT-F have different land sizes (0.406" L x 0.473" W vs. 0.406" L x 0.406" W). PCB footprint modification is required. Heights also differ (0.413" and 0.425"), requiring clearance verification.

Q: What is the difference between EEE-FK1V331P and EEE-FK1V331GP?

A: Both are Panasonic FK series parts with identical electrical specifications. EEE-FK1V331GP is rated for 5000 hours at 105°C, while EEE-FK1V331P is rated for 2000 hours at 105°C. Select EEE-FK1V331GP for applications requiring extended lifetime.

Q: Why is EEE-1VA331P listed as "Not For New Designs"?

A: EEE-1VA331P is transitioning out of production. While currently available, Panasonic recommends using active alternatives for new designs. EEE-FP1V331AP is the recommended replacement.

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

A: EEE-1VA331UAP is electrically compatible but rated for only 1000 hours at 85°C versus the original 2000 hours. Use only in applications where reduced lifetime is acceptable. For equivalent or improved reliability, select Tier 1 or Tier 2 alternatives.

Q: What packaging formats are available?

A: ECE-V1VA331P is supplied in bulk. Substitutes are available in Tape & Reel (TR), Cut Tape (CT) & Digi-Reel, or bulk formats depending on part number. Verify packaging compatibility with assembly processes.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitutes are ROHS3 compliant. The original ECE-V1VA331P is RoHS non-compliant. Compliance is mandatory for most applications and regulatory jurisdictions.
