LP470M400A1P3 Equivalent & Substitute Parts

Part Overview

The LP470M400A1P3 is a 47 µF, 400 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 in production with 1131 units in stock.

Substitute parts become necessary when the primary component reaches end-of-life status, experiences supply constraints, or when design requirements permit alternative manufacturers meeting identical electrical and mechanical specifications. The LP470M400A1P3 has one qualified substitute that maintains full compatibility across critical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP470M400A1P3 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match without exception:

Electrical Parameters:

• Capacitance: 47 µF (exact match required)
• Voltage Rating: 400 V (exact match required)
• Tolerance: ±20% (exact match required)
• Operating Temperature Range: -40°C to 105°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 10.00 mm (exact match required)
• Diameter: 22.00 mm (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 - Unlimited (exact match required)

The substitute part B43504A9476M000 meets all critical parameters and qualifies as a direct functional equivalent. Variations in lifetime rating (3000 Hrs @ 105°C versus 1000 Hrs @ 105°C) and height dimension (27.00 mm versus 25.00 mm) do not disqualify substitution, as these represent performance enhancements and minor mechanical tolerances within the snap-in package category.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (LP470M400A1P3): The LP470M400A1P3 remains the preferred selection for new designs and ongoing production. This component is active in production status with adequate inventory (1131 units in stock) and carries full ROHS3 compliance and REACH unaffected status.

Substitute Component (B43504A9476M000): The B43504A9476M000 manufactured by EPCOS - TDK Electronics is qualified as a direct substitute when the primary component is unavailable. This part carries "Not For New Designs" status, indicating it is suitable for replacement and maintenance applications only, not for new product development.

Selection Criteria:

• Use LP470M400A1P3 for new designs and production runs where supply is available
• Use B43504A9476M000 for field replacement, repair, and maintenance of existing equipment
• Both parts meet identical electrical specifications and mechanical mounting requirements
• The substitute part offers extended lifetime (3000 Hrs @ 105°C) compared to the primary part (1000 Hrs @ 105°C)
• Height variation (27.00 mm versus 25.00 mm) is within acceptable tolerance for snap-in package category and does not affect PCB layout compatibility

Frequently Asked Questions (FAQ)

Q: Can B43504A9476M000 be used as a direct replacement for LP470M400A1P3 in existing equipment?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 47 µF capacitance, 400 V rating, ±20% tolerance, -40°C to 105°C operating range, and identical snap-in package dimensions (22.00 mm diameter, 10.00 mm lead spacing). The 2.00 mm height difference (27.00 mm versus 25.00 mm) is within acceptable tolerance for through-hole snap-in applications.

Q: Why does B43504A9476M000 have "Not For New Designs" status?

A: This designation indicates the part is in mature production phase and is reserved for replacement and maintenance applications. For new product development, the LP470M400A1P3 should be specified. Both parts are functionally identical and suitable for equivalent applications.

Q: Are there differences in performance between these two parts?

A: The B43504A9476M000 provides enhanced lifetime rating (3000 Hrs @ 105°C versus 1000 Hrs @ 105°C). Both parts meet identical electrical specifications and operating temperature ranges. The substitute part includes additional performance data (ESR: 1.86 kOhm @ 100Hz, Ripple Current: 390 mA @ 100Hz, Impedance: 2.31 Ohms) not specified for the primary part.

Q: Will the height difference affect PCB layout?

A: No. The 2.00 mm height variation (25.00 mm to 27.00 mm) is within standard tolerance for snap-in aluminum electrolytic capacitors and does not affect PCB footprint or component placement. Both parts use identical lead spacing (10.00 mm) and diameter (22.00 mm).

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both LP470M400A1P3 and B43504A9476M000 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the inventory status for each part?

A: LP470M400A1P3 has 1131 units in stock (active production). B43504A9476M000 has 3203 units in stock (not for new designs). Availability should be confirmed with the supplier before design finalization.
