Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP331M200E3P3 is determined by strict equivalence in the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance: 330 µF (exact match)
• Tolerance: ±20% (exact match)
• Voltage Rating: 200 V (exact match or higher)
• Polarization: Polar (exact match)

Mechanical Compatibility Requirements:

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

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Product Status: Active (current production)

The substitute part 381LX331M200J012 meets all electrical and mechanical equivalence criteria. Variations in physical dimensions (diameter and height), ESR specifications, ripple current ratings, and lifetime ratings do not disqualify substitution when the core electrical and mechanical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: LP331M200E3P3

The LP331M200E3P3 is the specified component for applications where the exact physical dimensions (1.181" diameter, 1.181" height) and ESR characteristics (750mOhm @ 120Hz) are design requirements. This part is Active status with ROHS3 compliance and REACH unaffected designation, confirming current production and regulatory compliance.

Substitute Part: 381LX331M200J012

The 381LX331M200J012 is electrically and mechanically equivalent for general-purpose applications. This substitute maintains identical capacitance, voltage rating, tolerance, operating temperature range, and lead spacing. The substitute features a smaller physical footprint (0.984" diameter, 1.063" height) and extended lifetime rating (3000 Hrs @ 105°C versus 1000 Hrs @ 105°C). Both parts are Active status, ROHS3 compliant, and REACH unaffected.

Selection Basis:

• Both parts are manufactured by Cornell Dubilier Electronics (CDE)
• Both maintain identical electrical specifications (330 µF, ±20%, 200 V)
• Both are through-hole mounted with 0.394" (10.00mm) lead spacing
• Both are ROHS3 compliant and suitable for modern electronic equipment
• Substitution is valid when physical space constraints permit the smaller dimensions of the 381LX331M200J012

Frequently Asked Questions (FAQ)

Q: Can the 381LX331M200J012 be used as a direct replacement for the LP331M200E3P3?

A: Yes, the 381LX331M200J012 is electrically equivalent. Both parts have identical capacitance (330 µF), tolerance (±20%), voltage rating (200 V), operating temperature range (-40°C ~ 105°C), and lead spacing (0.394" / 10.00mm). The substitute has a smaller physical diameter (0.984" versus 1.181") and height (1.063" versus 1.181"), which must be verified against PCB layout constraints.

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

A: The primary differences are physical dimensions and lifetime rating. The LP331M200E3P3 has a larger can diameter and height. The 381LX331M200J012 offers extended lifetime (3000 Hrs @ 105°C versus 1000 Hrs @ 105°C) and higher ripple current ratings. ESR data for the 381LX331M200J012 is not specified in available documentation.

Q: Are both parts RoHS compliant?

A: Yes, both the LP331M200E3P3 and 381LX331M200J012 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What mounting considerations apply to these parts?

A: Both parts are through-hole mounted radial, can-style snap-in capacitors with identical 0.394" (10.00mm) lead spacing. PCB footprints are compatible. Physical space availability must be confirmed, as the 381LX331M200J012 has a smaller diameter and height.

Q: Can these parts be used interchangeably in all applications?

A: Electrical interchangeability is confirmed. Mechanical interchangeability depends on available PCB space. The smaller dimensions of the 381LX331M200J012 allow installation in tighter layouts. Applications requiring specific ESR characteristics should reference the LP331M200E3P3 specification (750mOhm @ 120Hz).

Q: What is the lead spacing for both parts?

A: Both parts have identical lead spacing of 0.394" (10.00mm), ensuring compatible PCB hole patterns and footprints.
