LP271M200E1P3 Equivalent & Substitute Parts

Part Overview

The LP271M200E1P3 is a 270 µF, 200 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in the LP series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct functional replacement in circuit applications. The LP271M200E1P3 has one qualified substitute within CDE's product portfolio that maintains core electrical specifications while offering extended operational lifetime.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP271M200E1P3 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 270 µF (exact match)
• Voltage rating: 200 V (exact match)
• Tolerance: ±20% (exact match)
• Polarization: Polar (exact match)
• Operating temperature range: -40°C to 105°C (exact match)

Mechanical Equivalence Requirements:

• Package type: Radial, Can - Snap-In (exact match)
• Mounting type: Through Hole (exact match)
• Lead spacing: 0.394" (10.00 mm) (exact match)

Compliance Requirements:

• RoHS3 compliance (required)
• Moisture sensitivity level: 1 (Unlimited) (required)

The substitute part 381LX271M200J012 meets all electrical and mechanical equivalence criteria. Differences in physical dimensions (diameter and height) and lifetime rating do not preclude substitution when circuit board layout and thermal management accommodate the alternative form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the LP271M200E1P3 and 381LX271M200J012 are active production parts from Cornell Dubilier Electronics with full RoHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is based on application-specific requirements:

LP271M200E1P3 Selection Criteria:

• Existing designs with validated board layout for 1.181" diameter, 0.984" height form factor
• Applications where physical space constraints require the larger diameter specification
• Designs where 1000-hour lifetime at 105°C meets thermal stress requirements

381LX271M200J012 Selection Criteria:

• New designs requiring compact form factor with 0.984" diameter, 1.063" height dimensions
• Applications benefiting from extended 3000-hour lifetime at 105°C
• Designs where higher ripple current capability (1.1 A @ 120 Hz, 1.5 A @ 20 kHz) is advantageous

Both parts maintain identical electrical performance in 270 µF, 200 V, ±20% tolerance specifications. Physical dimension differences require circuit board layout verification prior to substitution.

Frequently Asked Questions (FAQ)

Q: Can the 381LX271M200J012 be used as a direct replacement for the LP271M200E1P3?

A: Electrical substitution is valid. Both parts share identical capacitance (270 µF), voltage rating (200 V), tolerance (±20%), operating temperature range (-40°C to 105°C), lead spacing (10.00 mm), and mounting type (through-hole, radial snap-in). Physical dimensions differ: the 381LX series has a smaller diameter (0.984" vs. 1.181") but greater height (1.063" vs. 0.984"). Circuit board layout must accommodate these dimensional changes.

Q: What are the key differences between these two parts?

A: The primary differences are physical dimensions and operational lifetime. The LP271M200E1P3 features a larger diameter (30.00 mm) with shorter height (25.00 mm) and 1000-hour lifetime at 105°C. The 381LX271M200J012 has a smaller diameter (25.00 mm) with greater height (27.00 mm) and extended 3000-hour lifetime at 105°C. Electrical specifications are identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the LP271M200E1P3 and 381LX271M200J012 are RoHS3 compliant with moisture sensitivity level 1 (unlimited). Both parts are unaffected by REACH regulations and classified as EAR99 for export control purposes.

Q: What is the significance of the different lifetime ratings?

A: The LP271M200E1P3 is rated for 1000 hours at 105°C, while the 381LX271M200J012 is rated for 3000 hours at 105°C. This indicates the 381LX series maintains specified electrical characteristics for a longer duration under sustained thermal stress. Selection depends on application thermal profile and required service life.

Q: Do these parts have different ripple current ratings?

A: Yes. The LP271M200E1P3 handles 790 mA at 120 Hz (low frequency) and 1.106 A at 100 kHz (high frequency). The 381LX271M200J012 handles 1.1 A at 120 Hz and 1.5 A at 20 kHz. The 381LX series demonstrates higher ripple current capability, which may be beneficial in high-current applications.

Q: Can I use the 381LX271M200J012 in a design originally specified for the LP271M200E1P3?

A: Electrical substitution is valid provided circuit board layout accommodates the dimensional differences. The 381LX part is smaller in diameter but taller. Physical clearance around the capacitor location must be verified to ensure no mechanical interference with adjacent components or board features.
