Substitute Part Grouping Explanation

Substitution eligibility for the SLP331M200C1P3 is determined by strict equivalence in critical electrical parameters: capacitance value (330 µF), tolerance (±20%), and rated voltage (200 V). All identified substitutes maintain identical electrical specifications and the same through-hole, radial snap-in package form factor.

The substitute parts are classified as follows:

Upgrade Substitute: 381LX331M200J012 meets all core electrical requirements with extended operating temperature range (-40°C ~ 105°C versus -25°C ~ 105°C) and documented ripple current ratings at both low frequency (1.2 A @ 120 Hz) and high frequency (1.7 A @ 20 kHz). Physical dimensions vary slightly in height (1.063" versus 0.984"), remaining within through-hole mounting compatibility.

Similar Substitute: SLP331M200A3P3 shares the same CDE SLP0712TE series lineage with identical electrical specifications, ESR (603 mOhm), and lifetime rating (3000 Hrs @ 105°C). Physical dimensions differ in both diameter (0.866" versus 0.984") and height (1.181" versus 0.984"), requiring board layout verification for clearance compatibility.

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, ensuring current manufacturer support and environmental regulatory alignment.

The 381LX331M200J012 upgrade substitute offers extended temperature operation to -40°C and includes ripple current specifications, supporting applications requiring broader thermal performance. Physical height increase of 0.079" (2.00 mm) requires PCB clearance validation.

The SLP331M200A3P3 similar substitute maintains identical ESR and series characteristics but exhibits smaller diameter (0.866" versus 0.984") and greater height (1.181" versus 0.984"). Board layout verification is required to confirm both lateral spacing and vertical clearance compatibility.

All substitutes share common lead spacing (0.394" / 10.00 mm), supporting direct footprint implementation with physical envelope consideration.

Frequently Asked Questions (FAQ)

Q: Can 381LX331M200J012 directly replace SLP331M200C1P3? A: Electrical compatibility is confirmed: identical capacitance (330 µF), tolerance (±20%), and voltage rating (200 V). Physical height increases from 0.984" to 1.063", requiring clearance verification on the target PCB. Lead spacing remains constant at 0.394" (10.00 mm).

Q: What are the key differences between the upgrade and similar substitutes? A: The 381LX331M200J012 upgrade provides extended operating temperature (-40°C minimum versus -25°C) and documented ripple current performance. The SLP331M200A3P3 similar substitute maintains identical ESR and thermal lifetime but reduces package diameter while increasing height, demanding more rigorous layout validation.

Q: Are all substitute parts ROHS3 compliant? A: Yes. SLP331M200C1P3, 381LX331M200J012, and SLP331M200A3P3 are all ROHS3 Compliant with MSL rating of 1 (Unlimited).

Q: Which substitute has the smallest physical footprint? A: SLP331M200A3P3 offers the smallest diameter at 0.866" (22.00 mm) compared to 0.984" (25.00 mm) for both the main part and 381LX331M200J012. However, it has the greatest height at 1.181" (30.00 mm).

Q: Can I use SLP331M200A3P3 if the original design has tight vertical space constraints? A: No. SLP331M200A3P3 height of 1.181" (30.00 mm) exceeds both the original SLP331M200C1P3 at 0.984" and the 381LX331M200J012 at 1.063". Vertical clearance must be confirmed before selection.

Q: What is the impact of missing ESR data for 381LX331M200J012? A: While ESR is not specified for 381LX331M200J012, ripple current ratings at low frequency (1.2 A @ 120 Hz) and high frequency (1.7 A @ 20 kHz) provide performance indicators for thermal loading conditions. Applications requiring specific ESR values should specify the SLP331M200A3P3 at 603 mOhm.
