LP470M450C1P3 Equivalent & Substitute Parts

Part Overview

The LP470M450C1P3 is a 47 µF, 450 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is rated for 1000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active and available in production quantities.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit operation at lower voltage ratings while maintaining equivalent capacitance and tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP470M450C1P3 is determined by the following criteria:

Primary Matching Parameters:

• Capacitance: 47 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 10.00 mm (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -40°C to 105°C (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: 400 V minimum (the LP470M450C1P3 operates at 450 V; substitutes rated at 400 V are acceptable for applications not requiring the full 450 V rating)
• Lifetime @ Temperature: 1000 Hrs minimum @ 105°C (higher ratings are acceptable)
• Physical dimensions: Minor variations in diameter and height are acceptable provided the snap-in footprint remains compatible with the mounting interface

The identified substitute B43504A9476M000 meets all primary matching parameters and operates at 400 V, making it suitable for applications where the circuit voltage does not exceed 400 V.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (LP470M450C1P3): The LP470M450C1P3 is the recommended selection for new designs. It carries Active product status, ensuring long-term availability and manufacturing support. This component is suitable for all applications requiring 47 µF capacitance at 450 V with general-purpose aluminum electrolytic performance.

Substitute Component (B43504A9476M000): The B43504A9476M000 is classified as "Not For New Designs" by the manufacturer. This designation indicates that while the component remains available in inventory, it is not recommended for incorporation into new product designs. However, this substitute is technically compatible for existing designs or applications where:

1. The circuit voltage does not exceed 400 V
2. The physical dimensions (22.00 mm diameter, 27.00 mm height) are compatible with the PCB layout
3. The extended lifetime rating (3000 Hrs @ 105°C) meets or exceeds application requirements

For new designs, the LP470M450C1P3 should be the primary selection. The B43504A9476M000 is suitable only for legacy system support or repair applications where the lower voltage rating is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the B43504A9476M000 be used as a direct replacement for the LP470M450C1P3 in all applications?

A: No. The B43504A9476M000 is rated at 400 V, while the LP470M450C1P3 is rated at 450 V. The substitute is only compatible with applications where the circuit voltage does not exceed 400 V. If the application requires 450 V operation, the LP470M450C1P3 must be used.

Q: What are the physical dimension differences between these two parts?

A: The LP470M450C1P3 has a diameter of 25.00 mm and height of 25.00 mm. The B43504A9476M000 has a diameter of 22.00 mm and height of 27.00 mm. Both use the same 10.00 mm lead spacing and snap-in mounting interface. Verify that the PCB layout accommodates the smaller diameter and greater height of the substitute before selection.

Q: Why is the B43504A9476M000 marked "Not For New Designs"?

A: This designation indicates that the manufacturer (EPCOS - TDK Electronics) is not actively promoting this component for new product development. However, the part remains available in inventory and is technically functional. For new designs, the LP470M450C1P3 (Active status) is the preferred choice.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the LP470M450C1P3 and B43504A9476M000 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference in lifetime ratings between these components?

A: The LP470M450C1P3 is rated for 1000 hours at 105°C. The B43504A9476M000 is rated for 3000 hours at 105°C. The substitute exceeds the primary component's lifetime specification, making it suitable for applications requiring extended operational life at elevated temperatures.

Q: Can these capacitors be used interchangeably on the same PCB?

A: Physical interchangeability depends on PCB layout. Both components use identical lead spacing (10.00 mm) and snap-in mounting, but the B43504A9476M000 has a smaller diameter (22.00 mm vs. 25.00 mm) and greater height (27.00 mm vs. 25.00 mm). Verify that the PCB footprint and surrounding component clearances accommodate these dimensional differences before substitution.
