Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 381LX331M200A202 is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 3000 Hrs @ 105°C (exact match required)
• Operating Temperature: -40°C to 105°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 10.00 mm (exact match required)

Compliance Requirements:

• RoHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The substitute part 381LX331M200J012 meets all electrical and compliance criteria. Physical dimensions (diameter and height) differ, and ripple current ratings are higher, but these variations do not prevent substitution when board space and thermal management allow for the dimensional differences.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: 381LX331M200A202

Use this part when board layout requires a capacitor with a 35.00 mm diameter and 22.00 mm maximum seated height. This configuration is suitable for applications with space constraints in the radial direction and where lower ripple current handling is acceptable.

Substitute Part: 381LX331M200J012

Use this part as a substitute when:

• The application can accommodate a 25.00 mm diameter (smaller) and 27.00 mm maximum seated height (taller) footprint
• Higher ripple current capacity is beneficial (1.2 A @ 120 Hz and 1.7 A @ 20 kHz versus 1.1 A and 1.5 A respectively)
• Board space in the radial direction is available

Both parts maintain identical electrical performance, thermal ratings, compliance certifications, and lead spacing. Selection between them is determined solely by physical board layout constraints and ripple current requirements. Both parts are Active status products from the same manufacturer series and are RoHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can 381LX331M200J012 be used as a direct replacement for 381LX331M200A202?

A: Yes, provided the printed circuit board layout accommodates the dimensional differences. The substitute part has a smaller diameter (25.00 mm versus 35.00 mm) but greater height (27.00 mm versus 22.00 mm). All electrical specifications, voltage ratings, capacitance values, and thermal characteristics are identical.

Q: What is the significance of the different ripple current ratings?

A: The substitute part 381LX331M200J012 has higher ripple current capacity (1.2 A @ 120 Hz and 1.7 A @ 20 kHz) compared to the primary part (1.1 A @ 120 Hz and 1.5 A @ 20 kHz). This indicates the substitute can handle greater AC current stress. Selection depends on the application's actual ripple current requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are RoHS3 compliant, have Moisture Sensitivity Level 1 (Unlimited), and are classified as REACH Unaffected with ECCN EAR99. Compliance status is identical.

Q: What determines whether these parts are substitutable?

A: Substitutability is based on matching capacitance (330 µF), voltage rating (200 V), tolerance (±20%), lifetime (3000 Hrs @ 105°C), operating temperature range (-40°C to 105°C), polarization (Polar), mounting type (Through Hole), package type (Radial, Can - Snap-In), and lead spacing (10.00 mm). Physical dimensions and ripple current ratings are secondary considerations dependent on application requirements.

Q: Can I use 381LX331M200J012 in a space designed for 381LX331M200A202?

A: Only if the board layout permits a smaller diameter (25.00 mm) and greater height (27.00 mm). The lead spacing remains identical at 10.00 mm, so the mounting holes align. Verify clearance above and around the component before substitution.

Q: Are both parts currently available?

A: Yes. The primary part 381LX331M200A202 has 967 pieces in stock. The substitute part 381LX331M200J012 has 5118 pieces in stock. Both maintain Active product status.
