PG2W331MND3040 Equivalent & Substitute Parts

Part Overview

The PG2W331MND3040 is a 330 µF, 450 V aluminum electrolytic capacitor manufactured by Chinsan (Elite) in a radial, can snap-in package. This component is rated for 5000 hours at 105°C and is designed for general-purpose applications requiring high-voltage energy storage and filtering. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical and mechanical specifications are required due to component availability, inventory constraints, or design flexibility within established parameter tolerances.

Substitute Part Grouping Explanation

Substitute parts for the PG2W331MND3040 are qualified based on strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance: 330 µF (exact match)
• Voltage Rating: 450 V (exact match)
• Tolerance: ±20% (exact match)
• Lifetime: 5000 Hrs @ 105°C (exact match)
• Operating Temperature Range: -25°C ~ 105°C (exact match)
• Polarization: Polar (exact match)

Mechanical Equivalence Requirements:

• Lead Spacing: 0.394" (10.00 mm) (exact match)
• Size / Dimension: 1.181" Dia (30.00 mm) (exact match)
• Height - Seated (Max): 1.654" (42.00 mm) (exact match)
• Mounting Type: Through Hole (exact match)
• Package / Case: Radial, Can - Snap-In (exact match)

Compliance Requirements:

• RoHS3 Compliant (required)
• ECCN: EAR99 (maintained across all parts)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the PG2W331MND3040 in applications where these specifications are required.

Parameter Comparison

Engineering Selection Recommendations

All three parts—PG2W331MND3040 (Chinsan), 450VXH330MEFCSN30X40 (Rubycon), and ELXS451VSN331MR40S (Chemi-Con)—are Active products with full RoHS3 compliance and EAR99 classification. Each part satisfies the complete set of electrical and mechanical requirements for 330 µF, 450 V aluminum electrolytic capacitor applications.

Chinsan PG2W331MND3040: Suitable for general-purpose applications with 808 units currently in stock. Meets all baseline specifications with 1.45 A ripple current at 120 Hz.

Rubycon 450VXH330MEFCSN30X40: Offers enhanced ripple current performance with 1.75 A at 120 Hz and 2.45 A at 10 kHz. Inventory availability is 100,400 units. REACH Unaffected status is documented.

Chemi-Con ELXS451VSN331MR40S: Provides intermediate ripple current specifications with 1.52 A at 120 Hz and 2.1736 A at 50 kHz. Inventory availability is 1,292 units. REACH Unaffected status is documented.

Selection between these parts is determined by application-specific ripple current requirements, inventory availability, and supply chain considerations. All three parts are electrically and mechanically interchangeable within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can the Rubycon 450VXH330MEFCSN30X40 be used as a direct replacement for the Chinsan PG2W331MND3040?

A: Yes. Both parts are rated at 330 µF, 450 V with ±20% tolerance, 5000 hours lifetime at 105°C, and identical physical dimensions (30 mm diameter, 42 mm height, 10 mm lead spacing). Both are RoHS3 compliant and mounted through-hole in radial snap-in packages. The parts are electrically and mechanically interchangeable.

Q: What is the difference in ripple current performance between these three parts?

A: Ripple current specifications vary by frequency and manufacturer. At 120 Hz, the Chinsan part provides 1.45 A, the Rubycon part provides 1.75 A, and the Chemi-Con part provides 1.52 A. At higher frequencies, ripple current ratings differ based on manufacturer design. Selection should be based on the specific ripple current requirements of the application circuit.

Q: Are all three parts suitable for high-temperature applications?

A: Yes. All three parts are rated for operation across the -25°C to 105°C temperature range with 5000 hours lifetime at 105°C. They are suitable for applications requiring sustained high-temperature performance within this envelope.

Q: Do these parts have the same physical footprint?

A: Yes. All three parts share identical mechanical specifications: 1.181 inches (30.00 mm) diameter, 1.654 inches (42.00 mm) maximum seated height, and 0.394 inches (10.00 mm) lead spacing. They are direct mechanical substitutes for through-hole PCB mounting.

Q: What is the moisture sensitivity rating for these parts?

A: The Chinsan PG2W331MND3040 has MSL 1 (Unlimited). The Rubycon 450VXH330MEFCSN30X40 has MSL 1 (Unlimited). The Chemi-Con ELXS451VSN331MR40S is listed as Not Applicable for MSL. All three parts are suitable for standard storage and handling conditions.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are RoHS3 compliant and carry EAR99 export classification. They meet environmental and regulatory requirements for industrial and commercial applications.
