Substitute Part Grouping Explanation

Substitution of the SLP331M200C3P3 is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance: 330 µF (fixed requirement)
• Tolerance: ±20% (fixed requirement)
• Voltage Rating: 200 V minimum (equal or higher acceptable)
• ESR: 603 mOhm (equivalent performance)
• Lifetime: 3000 Hours @ 105°C (fixed requirement)
• Operating Temperature: -25°C to 105°C minimum range
• Lead Spacing: 0.394" (10.00 mm) (fixed requirement)
• Package Type: Radial, Can - Snap-In (fixed requirement)
• Mounting Type: Through Hole (fixed requirement)

Substitution Categories:

Direct Equivalent: SLP331M200C1P3 maintains identical electrical specifications (330 µF, 200 V, ±20%, 603 mOhm, 3000 Hrs @ 105°C) with active product status. Height differs (0.984" vs. 1.181"), accommodating space-constrained applications.

Voltage Upgrade Substitutes: SLP331M220C1P3 and SLP331M250C3P3 provide higher voltage ratings (220 V and 250 V respectively) while maintaining all other electrical parameters. These are suitable for applications where voltage margin enhancement is required.

Dimensional Variant: SLP331M200A3P3 maintains electrical specifications with a reduced case diameter (0.866" vs. 0.984"), applicable to compact board layouts.

Cross-Manufacturer Upgrade: LGU2E331MELA (Nichicon) provides 330 µF, 250 V rating with extended operating temperature range (-40°C to 105°C) and active product status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): SLP331M200C1P3 is the primary direct equivalent. Active product status ensures supply chain continuity. The reduced height (0.984" vs. 1.181") provides additional design flexibility for space-constrained applications without compromising electrical specifications.

For Voltage Margin Enhancement: SLP331M220C1P3 and SLP331M250C3P3 are suitable when circuit design permits higher voltage ratings. Both maintain identical capacitance, tolerance, ESR, and lifetime specifications. SLP331M250C3P3 matches the original height (1.181"), while SLP331M220C1P3 offers a more compact profile (0.984").

For Compact Board Layouts: SLP331M200A3P3 accommodates space-constrained designs with a reduced case diameter (0.866") while maintaining all electrical parameters and original height.

For Extended Temperature Range: LGU2E331MELA (Nichicon) provides an operating temperature range of -40°C to 105°C, exceeding the original -25°C to 105°C specification. This cross-manufacturer option is suitable for applications requiring enhanced low-temperature performance. All components are ROHS3 compliant and REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can SLP331M200C1P3 be used as a direct replacement for SLP331M200C3P3?

A: Yes. Both parts share identical electrical specifications: 330 µF capacitance, 200 V voltage rating, ±20% tolerance, 603 mOhm ESR, and 3000-hour lifetime at 105°C. The primary difference is height (0.984" vs. 1.181"), which is a mechanical advantage in space-constrained applications. SLP331M200C1P3 has active product status.

Q: What is the difference between the CDE and Nichicon options?

A: Both manufacturers provide 330 µF, 250 V aluminum electrolytic capacitors with 3000-hour lifetime at 105°C. LGU2E331MELA (Nichicon) extends the operating temperature range to -40°C, compared to -25°C for CDE parts. ESR specifications are not provided for the Nichicon part. Selection depends on low-temperature performance requirements and supplier availability.

Q: Can I use a 220 V or 250 V rated capacitor in place of the 200 V original?

A: Yes. Higher voltage ratings are electrically compatible with 200 V circuit designs. SLP331M220C1P3 and SLP331M250C3P3 maintain all other electrical parameters while providing voltage margin. This is a standard engineering practice for reliability enhancement.

Q: Are all substitute parts through-hole mounted?

A: Yes. All listed substitutes are through-hole mounted with 0.394" (10.00 mm) lead spacing, matching the original SLP331M200C3P3 package configuration.

Q: What is the significance of the case diameter difference in SLP331M200A3P3?

A: SLP331M200A3P3 has a reduced case diameter of 0.866" compared to 0.984" in other options. This dimensional variant is suitable for compact printed circuit board layouts where radial space is limited. All electrical specifications remain identical.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
