LPX391M200C1P3 Equivalent & Substitute Parts

Part Overview

The LPX391M200C1P3 is a 390 µF, 200 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in the LPX series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring stable capacitance and reliable performance across industrial temperature ranges. The part is currently Active in product status and fully compliant with RoHS3 and REACH regulations.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct replacement without circuit redesign. Substitution becomes necessary due to inventory availability, lead time constraints, or application-specific performance requirements such as extended lifetime ratings or improved ripple current handling.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LPX391M200C1P3 is determined by strict equivalence in the following parameters:

Critical Electrical Parameters:

• Capacitance: 390 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 200 V (exact match required)
• Polarization: Polar (exact match required)

Critical Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 10.00 mm (exact match required)
• Size / Dimension: 25.00 mm Dia (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The substitute part 380LX391M200J012 meets all critical electrical and mechanical parameters. Performance characteristics such as ESR, lifetime rating, and ripple current capacity may vary within acceptable engineering tolerances for the application category.

Parameter Comparison

Engineering Selection Recommendations

Both the LPX391M200C1P3 and 380LX391M200J012 are Active products manufactured by Cornell Dubilier Electronics and fully compliant with RoHS3 and REACH regulations. Both parts are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements during storage or assembly.

The 380LX391M200J012 offers improved performance characteristics within the same electrical and mechanical envelope:

• Lower ESR (470 mOhm versus 510 mOhm at 120 Hz) reduces heat generation
• Extended lifetime rating (3000 Hrs versus 1000 Hrs at 85°C) provides longer operational life
• Increased ripple current capacity at high frequency (2.4 A at 20 kHz versus 1.76 A at 50 kHz)
• Marginal height increase (27.00 mm versus 25.00 mm) remains within typical PCB layout tolerances for snap-in capacitor mounting

Selection between these parts depends on application requirements for thermal performance, operational lifetime, and ripple current handling. Both parts are suitable for general-purpose applications and maintain identical electrical ratings and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 380LX391M200J012 be used as a direct replacement for the LPX391M200C1P3?

A: Yes. Both parts share identical capacitance (390 µF), voltage rating (200 V), tolerance (±20%), lead spacing (10.00 mm), and mounting configuration (Through Hole, Radial, Can - Snap-In). Both are RoHS3 compliant and MSL 1 rated. The 2 mm height difference (27.00 mm versus 25.00 mm) is within standard PCB layout tolerances for snap-in capacitor installations.

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

A: The 380LX391M200J012 provides lower ESR (470 mOhm versus 510 mOhm), higher ripple current capacity at high frequency (2.4 A at 20 kHz), and extended lifetime (3000 Hrs versus 1000 Hrs at 85°C). These improvements reduce thermal stress and extend service life in demanding applications.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity). Both carry identical regulatory status and are suitable for equivalent applications.

Q: Does the height difference affect PCB layout compatibility?

A: The 380LX391M200J012 is 2 mm taller (27.00 mm versus 25.00 mm). This variation is typical for snap-in capacitor designs and generally does not affect PCB layout compatibility. Verify clearance in your specific application if height-constrained mounting space exists.

Q: Which part should be selected for new designs?

A: Selection depends on application performance requirements. The 380LX391M200J012 is recommended for applications requiring extended lifetime, lower thermal dissipation, or higher ripple current handling. The LPX391M200C1P3 remains suitable for standard general-purpose applications with standard thermal and lifetime requirements.

Q: Are both parts available in equivalent quantities?

A: Inventory availability varies. LPX391M200C1P3 has 840 Pcs in stock; 380LX391M200J012 has 782 Pcs in stock. Verify current availability with your supplier for procurement planning.
