LP271M250C3P3 Equivalent & Substitute Parts

Part Overview

The LP271M250C3P3 is a 270 µF, 250 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 polarized energy storage and filtering in circuits operating up to 105°C. The part is Active status and ROHS3 compliant.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct replacement in the same circuit application without functional degradation. Substitution is necessary when the primary part becomes unavailable or when alternative inventory sources are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for aluminum electrolytic capacitors is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match Exactly):

• Capacitance: 270 µF
• Voltage Rating: 250 V
• Tolerance: ±20%
• Polarization: Polar
• Mounting Type: Through Hole
• Package Style: Radial, Can - Snap-In
• Lead Spacing: 0.394" (10.00mm)
• Operating Temperature Range: -40°C ~ 105°C
• RoHS Compliance: ROHS3 Compliant

Performance Parameters (May Vary Within Acceptable Ranges):

• ESR (Equivalent Series Resistance)
• Lifetime @ Temperature
• Ripple Current ratings
• Physical dimensions (diameter and height)

The substitute part 381LR271M250H022 meets all critical parameter requirements and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the LP271M250C3P3 and 381LR271M250H022 are Active status products manufactured by Cornell Dubilier Electronics and are ROHS3 compliant. Both parts meet the electrical and mechanical requirements for 270 µF, 250 V polarized aluminum electrolytic capacitor applications.

The 381LR271M250H022 offers improved performance characteristics: lower ESR (737 mOhm versus 922 mOhm at 120 Hz) and extended lifetime rating (3000 hours versus 1000 hours at 105°C). Higher ripple current ratings are also provided by the substitute part.

Physical dimensions differ slightly. The 381LR271M250H022 has a smaller diameter (22.00mm versus 25.00mm) but greater height (32.00mm versus 30.00mm). Lead spacing remains identical at 10.00mm, maintaining PCB compatibility for snap-in mounting.

Selection between these parts depends on available inventory, physical space constraints within the application, and performance requirements. Both parts are suitable for general-purpose applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 381LR271M250H022 be used as a direct replacement for the LP271M250C3P3?

A: Yes. Both parts share identical capacitance (270 µF), voltage rating (250 V), tolerance (±20%), lead spacing (10.00mm), mounting type (through hole), package style (radial, can - snap-in), and operating temperature range (-40°C ~ 105°C). Both are ROHS3 compliant and Active status products from the same manufacturer.

Q: What are the physical dimension differences?

A: The LP271M250C3P3 has a diameter of 25.00mm and height of 30.00mm. The 381LR271M250H022 has a diameter of 22.00mm and height of 32.00mm. Lead spacing is identical at 10.00mm for both parts. Verify PCB layout clearances before substitution if space is constrained.

Q: Does the lower ESR of the 381LR271M250H022 affect compatibility?

A: No. Lower ESR (737 mOhm versus 922 mOhm at 120 Hz) is a performance improvement that does not affect functional compatibility. The substitute part will perform equivalently or better in the same circuit.

Q: Are the ripple current ratings different?

A: Yes. The 381LR271M250H022 provides higher ripple current ratings: 1.42 A at 120 Hz (versus 840 mA) and 2.03 A at 20 kHz (versus 1.176 A at 100 kHz). This represents improved performance capability and does not affect substitution eligibility.

Q: What is the difference in lifetime rating?

A: The LP271M250C3P3 is rated for 1000 hours at 105°C. The 381LR271M250H022 is rated for 3000 hours at 105°C. The substitute part offers extended operational life under thermal stress conditions.

Q: Are both parts available in the same packaging format?

A: Both parts use radial, can-style snap-in packaging with through-hole mounting. The LP271M250C3P3 is supplied in standard packaging, while the 381LR271M250H022 is supplied in bulk packaging. Functional compatibility is identical.

Q: Do compliance certifications differ between the two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8532.22.0040. Moisture sensitivity level is 1 (unlimited) for both parts.
