Key Parameters

Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors is governed by strict electrical and mechanical compatibility requirements. All substitute parts for the 380LX331M200K202 maintain identical core electrical specifications: 330 µF capacitance, 200 V voltage rating, ±20% tolerance, 603 mOhm ESR, and 3000 hours lifetime rating at 85°C.

Mechanical compatibility is ensured through common snap-in package type and through-hole mounting methodology. All substitute parts maintain the specified lead spacing of 0.394" (10.00 mm), permitting direct PCB placement compatibility. Physical dimensions vary within acceptable design parameters to accommodate different internal construction methods while maintaining functional equivalence.

All substitutes maintain identical compliance certifications: ROHS3 compliance and REACH unaffected status ensure regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

SLPX331M200A1P3 is the recommended substitute for the 380LX331M200K202. Both components are in active product status with current manufacturing availability. This substitution maintains all critical electrical parameters including capacitance, voltage rating, tolerance, ESR, and lifetime specifications. The component features improved ripple current handling at 1.51 A @ 120 Hz compared to the main part at 1.0 A. Physical dimensions are reduced to 0.866" diameter with 0.984" maximum seated height, providing a more compact footprint while maintaining electrical equivalence.

SLPX331M200A3P3 is available as an alternative substitute; however, this component carries an obsolete product status designation. While electrically equivalent with 603 mOhm ESR and identical lifetime characteristics, obsolete status indicates this part is no longer in active production. Selection of this substitute should occur only when supply of active alternatives is constrained. Physical dimensions are 0.866" diameter with 1.181" maximum seated height.

All substitutes maintain ROHS3 compliance and REACH unaffected regulatory status, ensuring no compliance degradation relative to the primary part.

Frequently Asked Questions (FAQ)

Q: Can SLPX331M200A1P3 and SLPX331M200A3P3 be used interchangeably with 380LX331M200K202?

A: Both components are electrically equivalent with identical capacitance, voltage rating, tolerance, ESR, and lifetime specifications. Through-hole mounting with identical lead spacing permits direct PCB compatibility. Physical dimension differences (diameter and height) require verification against available PCB clearance during layout design.

Q: What are the primary differences between the substitute parts?

A: The two SLPX series substitutes share identical electrical characteristics but differ in physical dimensions and product status. SLPX331M200A1P3 measures 0.866" diameter by 0.984" height with active product status. SLPX331M200A3P3 measures 0.866" diameter by 1.181" height with obsolete product status. Both provide enhanced ripple current ratings compared to the 380LX series.

Q: Are there dimensional constraints when selecting between the main part and substitutes?

A: Yes. The 380LX331M200K202 measures 1.181" diameter by 0.866" height. Substitute parts measure 0.866" diameter with varying heights (0.984" or 1.181"). Design layouts requiring maximum diameter tolerance specifications may not accommodate the SLPX substitutes. Verification of PCB footprint clearance is necessary before final component selection.

Q: How do ripple current ratings differ between these parts?

A: The 380LX331M200K202 is rated for 1.0 A ripple current at 120 Hz. SLPX331M200A1P3 supports 1.51 A @ 120 Hz. SLPX331M200A3P3 supports 1.63 A @ 120 Hz. Higher ripple current capability in substitute parts permits use in applications with greater AC current demands while maintaining thermal operating parameters.

Q: Should product status influence component selection?

A: SLPX331M200A1P3 maintains active product status with current manufacturing continuity. SLPX331M200A3P3 carries obsolete designation, indicating discontinued production. For new design implementations or long-term supply requirements, SLPX331M200A1P3 is the preferred selection. SLPX331M200A3P3 selection is appropriate only when immediate availability overrides supply continuity concerns.

Q: Are compliance certifications identical across all three components?

A: Yes. All three parts are ROHS3 compliant and carry REACH unaffected status. No compliance degradation occurs when substituting between any of these three aluminum electrolytic capacitors.
