LDECG4470KA0N00 Film Capacitor Equivalent & Substitute Parts

Part Overview

The LDECG4470KA0N00 is a 4.7 µF film capacitor manufactured by KEMET, designed for automotive applications requiring high-temperature operation. This surface-mount component utilizes polyester and polyethylene naphthalate (PEN) metallized-stacked dielectric technology in a 5040 package format. The part maintains Active product status and carries AEC-Q200 automotive qualification, making it suitable for demanding automotive environments operating between -55°C and 125°C. Equivalent substitute parts are identified based on matching capacitance, tolerance, package dimensions, dielectric material, mounting type, and automotive compliance ratings while allowing for higher voltage ratings within the same physical footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LDECG4470KA0N00 are identified based on strict parameter matching in the following critical categories:

Electrical Parameters (Must Match):

• Capacitance: 4.7 µF
• Tolerance: ±10%
• AC Voltage Rating: 40V

Mechanical Parameters (Must Match):

• Package / Case: 5040 (127102 Metric)
• Size / Dimension: 0.512" L x 0.409" W (13.00mm x 10.40mm)
• Height - Seated (Max): 0.161" (4.10mm)
• Mounting Type: Surface Mount
• Termination: Solder Pads

Material & Environmental Parameters (Must Match):

• Dielectric Material: Polyester, Polyethylene Naphthalate (PEN), Metallized - Stacked
• Operating Temperature: -55°C ~ 125°C
• Automotive Applications: AEC-Q200 Rated

Allowable Variation:

• DC Voltage Rating: May be equal to or higher than 50V, provided all other parameters remain identical

The LDEDG4470KA0N00 qualifies as a parametric equivalent because it maintains identical capacitance, tolerance, AC voltage rating, package dimensions, dielectric composition, temperature range, and automotive compliance while offering an elevated DC voltage rating of 63V. This higher voltage rating does not compromise compatibility in applications designed for the 50V specification.

Engineering Selection Recommendations

LDECG4470KA0N00 Primary Selection: Select the LDECG4470KA0N00 when the application circuit is designed specifically for 50V DC operation and component inventory availability is not a constraint. This part maintains Active product status with full AEC-Q200 automotive qualification and ROHS3 compliance.

LDEDG4470KA0N00 Substitute Selection: The LDEDG4470KA0N00 serves as a direct substitute when the LDECG4470KA0N00 is unavailable or when supply chain considerations require alternative sourcing. The elevated 63V DC rating provides additional voltage margin without altering electrical performance in 50V-rated circuits. Both parts carry identical AEC-Q200 automotive ratings, ROHS3 compliance, and MSL-3 moisture sensitivity specifications, ensuring equivalent reliability in automotive applications. The substitute part maintains identical physical dimensions, mounting characteristics, and thermal operating range (-55°C to 125°C).

Frequently Asked Questions (FAQ)

Q: Can the LDEDG4470KA0N00 (63V) be used in place of the LDECG4470KA0N00 (50V)?

A: Yes. The LDEDG4470KA0N00 is a direct substitute. The higher DC voltage rating (63V versus 50V) does not create compatibility issues in circuits designed for 50V operation. All other electrical, mechanical, and environmental parameters are identical, including capacitance (4.7 µF), tolerance (±10%), AC voltage rating (40V), package dimensions (5040), dielectric material, operating temperature range (-55°C to 125°C), and automotive compliance (AEC-Q200).

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the LDECG4470KA0N00 and LDEDG4470KA0N00 share identical package specifications: 5040 (127102 Metric) with dimensions of 0.512" L x 0.409" W (13.00mm x 10.40mm) and maximum seated height of 0.161" (4.10mm). They are interchangeable in PCB layouts without modification.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both parts carry AEC-Q200 automotive ratings, ROHS3 compliance, and MSL-3 moisture sensitivity specifications. They are suitable for automotive applications operating across the full temperature range of -55°C to 125°C.

Q: What is the difference between the LDECG and LDEDG series designations?

A: The series designation (LDECG versus LDEDG) reflects the DC voltage rating classification within KEMET's film capacitor product line. The LDECG series is rated for 50V DC, while the LDEDG series is rated for 63V DC. All other performance characteristics, including capacitance value, tolerance, dielectric material, and package format, remain consistent across these series variants.

Q: Can the LDECG4470KA0N00 be substituted with a lower voltage-rated part?

A: No. Substitution with lower voltage-rated parts is not permitted. The LDECG4470KA0N00 is specified for 50V DC operation. Using a part rated below 50V would violate electrical safety margins and is not a valid substitution.

Q: Are there inventory considerations between these two parts?

A: Yes. Current inventory levels differ: LDECG4470KA0N00 has 1095 pieces in stock, while LDEDG4470KA0N00 has 1470 pieces in stock. Both are available as new original components in Tape & Reel (TR) packaging.
