SLPX331M180A1P3 Equivalent & Substitute Parts

Part Overview

The SLPX331M180A1P3 is a 330 µF, 180 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in the SLPX series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring stable capacitance and low equivalent series resistance over extended operational life. The part is currently Active in product status with 1189 units in stock.

Substitute parts become necessary when the original component reaches end-of-life status, inventory depletion, or when design requirements permit operation at higher voltage ratings while maintaining identical capacitance and physical form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLPX331M180A1P3 is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Lead Spacing: 10.00 mm (exact match required)
• Diameter: 22.00 mm (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Series: SLPX (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than 180 V
• Height - Seated (Max): May vary within physical board clearance constraints
• ESR @ 120 Hz: Equivalent or lower values acceptable
• Ripple Current: Equal or higher values acceptable
• Product Status: Active preferred; Obsolete acceptable if all other parameters match

Two substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations

SLPX331M200A1P3 (Upgrade Substitute)

This part is the primary substitute option. It maintains identical capacitance (330 µF), tolerance (±20%), ESR (603 mOhm @ 120 Hz), lifetime rating (3000 Hrs @ 85°C), physical dimensions (22.00 mm diameter, 25.00 mm height), and lead spacing (10.00 mm) as the original SLPX331M180A1P3. The voltage rating is increased from 180 V to 200 V, providing enhanced voltage margin in the circuit. The part is Active in product status with higher inventory availability (3431 units). Both parts are ROHS3 Compliant and REACH Unaffected, ensuring regulatory compliance continuity.

SLPX331M200A3P3 (Similar Substitute)

This part matches all mandatory electrical parameters (330 µF capacitance, ±20% tolerance, 603 mOhm ESR, 3000 Hrs @ 85°C lifetime, 200 V rating) and physical lead spacing (10.00 mm) and diameter (22.00 mm). The seated height is 30.00 mm, which exceeds the original 25.00 mm specification. This part is marked Obsolete in product status, indicating discontinued manufacturing. Selection of this part is contingent upon board-level clearance verification to accommodate the additional 5.00 mm height. ROHS3 Compliance and REACH Unaffected status are maintained.

Frequently Asked Questions (FAQ)

Q: Can SLPX331M200A1P3 be used as a direct replacement for SLPX331M180A1P3?

A: Yes. The SLPX331M200A1P3 is a direct substitute. It maintains identical capacitance (330 µF), tolerance (±20%), ESR (603 mOhm @ 120 Hz), lifetime (3000 Hrs @ 85°C), and physical form factor (22.00 mm diameter, 25.00 mm height, 10.00 mm lead spacing). The increased voltage rating (200 V vs. 180 V) is compatible with circuits designed for 180 V operation.

Q: What is the difference between SLPX331M200A1P3 and SLPX331M200A3P3?

A: Both parts share identical electrical specifications (330 µF, ±20%, 603 mOhm ESR, 3000 Hrs @ 85°C, 200 V). The primary differences are: (1) SLPX331M200A1P3 is Active; SLPX331M200A3P3 is Obsolete; (2) SLPX331M200A1P3 has a seated height of 25.00 mm; SLPX331M200A3P3 has a seated height of 30.00 mm; (3) SLPX331M200A1P3 has higher inventory availability (3431 units vs. 1129 units).

Q: Why is the height different between SLPX331M200A1P3 and SLPX331M200A3P3?

A: The SLPX331M200A3P3 has a maximum seated height of 30.00 mm compared to 25.00 mm for SLPX331M200A1P3. This 5.00 mm difference reflects design variations within the SLPX series. Board-level clearance must be verified before selecting SLPX331M200A3P3 to ensure the taller component does not interfere with adjacent circuitry or enclosure constraints.

Q: Are all three parts RoHS compliant?

A: Yes. SLPX331M180A1P3, SLPX331M200A1P3, and SLPX331M200A3P3 are all ROHS3 Compliant and REACH Unaffected, ensuring regulatory compliance for applications subject to these standards.

Q: What is the significance of the "A1P3" and "A3P3" designations in the part numbers?

A: These designations are manufacturer-specific codes within the SLPX series. The "A1P3" and "A3P3" suffixes differentiate product variants, including design revisions and manufacturing specifications. Both designations are valid for the 330 µF, 200 V configuration, but SLPX331M200A1P3 is the current Active variant.

Q: Can SLPX331M200A3P3 be used if SLPX331M200A1P3 is unavailable?

A: SLPX331M200A3P3 is a functional equivalent if board-level height clearance permits the additional 5.00 mm. However, SLPX331M200A3P3 is marked Obsolete, indicating discontinued production. SLPX331M200A1P3 is the recommended substitute due to Active status and higher inventory availability.

Q: What are the ripple current specifications for each part?

A: SLPX331M180A1P3: 1.49 A @ 120 Hz, 2.19 A @ 20 kHz. SLPX331M200A1P3: 1.51 A @ 120 Hz, 2.22 A @ 20 kHz. SLPX331M200A3P3: 1.63 A @ 120 Hz, 2.4 A @ 20 kHz. All three parts support the ripple current requirements of general-purpose applications within their respective voltage ratings.
