Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLP331M220A5P3 are classified based on the following criteria:

Upgrade Substitutes maintain identical capacitance (330 µF) and tolerance (±20%) while increasing the rated voltage to 250 V. These parts operate within the same series (SLP0712TE) and preserve all mechanical dimensions and mounting characteristics. Upgrade substitutes provide enhanced voltage margin for the same application footprint.

Direct Equivalents match the original part's electrical specifications (330 µF, 220 V, ±20% tolerance) and mechanical form factor while originating from alternative manufacturers. These parts satisfy identical circuit requirements and occupy the same board space.

Key Parameters Determining Substitution:

• Capacitance value: 330 µF (fixed)
• Tolerance: ±20% (fixed)
• Voltage rating: 220 V (minimum) or higher
• ESR: 603 mOhm (nominal)
• Lifetime: 3000 Hrs @ 105°C (minimum)
• Lead spacing: 10.00 mm (fixed)
• Diameter: 22.00 mm (fixed)
• Package type: Radial, Can - Snap-In (fixed)
• Mounting: Through Hole (fixed)

Engineering Selection Recommendations

SLP331M250A3P3 (CDE Upgrade Substitute)

This part is suitable for direct replacement when circuit design permits a higher voltage rating. The 250 V rating provides increased safety margin over the original 220 V specification while maintaining identical capacitance, tolerance, and ESR characteristics. The reduced height (30.00 mm versus 35.00 mm) offers improved board layout flexibility. All compliance certifications (ROHS3, REACH Unaffected, EAR99) match the original part. Product status is Active with 4312 units in stock.

SLP331M250A7P3 (CDE Upgrade Substitute)

This part provides the same electrical upgrade as SLP331M250A3P3 with an increased height of 40.00 mm. Selection of this variant depends on available vertical clearance in the application. Electrical performance, compliance status, and availability (3894 units in stock) are equivalent to SLP331M250A3P3.

LGU2P331MELZ (Nichicon Direct Equivalent)

This part matches the original SLP331M220A5P3 in capacitance, voltage rating, tolerance, and physical dimensions (35.00 mm height). The extended operating temperature range (-40°C to 105°C) provides additional thermal margin. ESR is not specified for this part. All compliance certifications are current (ROHS3, REACH Unaffected, EAR99). Product status is Active with 756 units in stock.

Frequently Asked Questions (FAQ)

Q: Can SLP331M250A3P3 or SLP331M250A7P3 be used as direct replacements for SLP331M220A5P3?

A: Yes. Both parts maintain the same capacitance (330 µF), tolerance (±20%), ESR (603 mOhm), and lifetime rating (3000 Hrs @ 105°C). The increased voltage rating (250 V versus 220 V) is compatible with circuits designed for 220 V operation. The primary difference is height: SLP331M250A3P3 is 30.00 mm (shorter) and SLP331M250A7P3 is 40.00 mm (taller). Verify available board space before selection.

Q: What is the difference between SLP331M250A3P3 and SLP331M250A7P3?

A: Both parts are electrically identical (330 µF, 250 V, 603 mOhm ESR, 3000 Hrs @ 105°C). The only difference is seated height: SLP331M250A3P3 measures 30.00 mm while SLP331M250A7P3 measures 40.00 mm. Select based on available vertical clearance in your application.

Q: Can LGU2P331MELZ replace SLP331M220A5P3?

A: Yes. LGU2P331MELZ is a direct equivalent from Nichicon with matching capacitance (330 µF), voltage rating (220 V), tolerance (±20%), and physical dimensions (22.00 mm diameter, 35.00 mm height). The extended operating temperature range (-40°C to 105°C) provides additional thermal capability. ESR is not specified for the Nichicon part.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. SLP331M250A3P3, SLP331M250A7P3, and LGU2P331MELZ are all ROHS3 Compliant and REACH Unaffected, matching the compliance status of the original SLP331M220A5P3.

Q: What is the lead spacing for all these parts?

A: All parts listed (SLP331M220A5P3, SLP331M250A3P3, SLP331M250A7P3, and LGU2P331MELZ) have identical lead spacing of 10.00 mm and diameter of 22.00 mm, ensuring compatibility with existing through-hole PCB layouts.

Q: Which substitute part has the lowest ESR?

A: SLP331M220A5P3, SLP331M250A3P3, and SLP331M250A7P3 all specify 603 mOhm ESR @ 120Hz. LGU2P331MELZ does not provide ESR specification in the available data.
