Key Parameters

Substitute Part Grouping Explanation

Equivalent and substitute parts for the LPX471M400H7P3 are classified based on the following critical electrical and mechanical parameters:

Primary Matching Criteria:

• Capacitance: 470 µF (exact match required)
• Voltage Rating: 400 V or higher
• Tolerance: ±20%
• Polarization: Polar (aluminum electrolytic)
• Lead Spacing: 0.394" (10.00 mm) (exact match required for PCB compatibility)
• Package Type: Radial, Can - Snap-In (exact match required for mechanical fit)
• Mounting Type: Through Hole

Substitution Parameters: Parts are substitutable when they maintain identical capacitance, lead spacing, package type, and mounting configuration, while meeting or exceeding the voltage rating, ESR characteristics, and ripple current specifications of the original part.

Engineering Selection Recommendations

LPX471M450H9P3 (Cornell Dubilier Electronics) This substitute is functionally equivalent to the LPX471M400H7P3 and maintains active product status. It features identical capacitance and tolerance specifications with an elevated voltage rating of 450 V, providing additional design margin. Physical dimensions and electrical characteristics remain comparable, supporting direct substitution with improved voltage headroom.

B43305B9477M000 (EPCOS - TDK Electronics) This part is marked "Not For New Designs" and substitutes at the 400 V rating level. It offers improved ESR characteristics (290 mOhm @ 100 Hz) and extended lifetime (2000 Hrs @ 85°C) relative to the LPX471M400H7P3. The physical diameter is reduced to 1.181" (30.00 mm) from the original 1.378" (35.00 mm), requiring PCB layout verification for mechanical fit compatibility.

B43501A9477M000 (EPCOS - TDK Electronics) This part is marked "Not For New Designs" and provides the most favorable electrical characteristics among substitutes, with lowest ESR (140 mOhm @ 100 Hz) and highest rated lifetime (10000 Hrs @ 85°C). It substitutes at the 400 V rating with identical capacitance. The height dimension extends to 1.772" (45.00 mm) from the original 1.575" (40.00 mm), requiring vertical clearance verification on the PCB.

Frequently Asked Questions (FAQ)

What electrical characteristics must remain identical when selecting a substitute? Capacitance value (470 µF) and tolerance (±20%) must be identical. Lead spacing (0.394" / 10.00 mm) must match exactly for PCB hole placement compatibility. Voltage rating may be equal to or higher than the original 400 V specification.

Can B43305B9477M000 be used in place of LPX471M400H7P3? B43305B9477M000 meets the electrical specifications for substitution with equivalent 400 V rating and matching capacitance. However, its reduced physical diameter (30.00 mm vs. 35.00 mm original) requires PCB layout evaluation to confirm adequate clearance and mechanical stability within the snap-in retention mechanism.

Is LPX471M450H9P3 a direct replacement? LPX471M450H9P3 is a direct functional substitute. It maintains identical physical dimensions and package specifications as the original LPX471M400H7P3, with the benefit of higher voltage rating (450 V). No PCB layout modifications are required.

What is the advantage of B43501A9477M000? B43501A9477M000 provides superior electrical performance with significantly lower ESR (140 mOhm @ 100 Hz vs. 423 mOhm @ 120 Hz) and extended component lifetime (10000 Hrs @ 85°C vs. 1000 Hrs @ 85°C). The increased height (1.772" / 45.00 mm) requires vertical space confirmation on the PCB.

Why are B43305B9477M000 and B43501A9477M000 marked "Not For New Designs"? The "Not For New Designs" designation indicates these parts are mature products no longer recommended for new circuit development by the manufacturer. They remain functionally available for replacement in existing designs or where legacy compatibility is required.

Does package type affect substitution compatibility? All substitutes maintain the Radial, Can - Snap-In package and Through Hole mounting type required for mechanical fit. Lead spacing of 0.394" (10.00 mm) is identical across all options. Physical diameter and height variations exist and must be evaluated against available PCB space.
