LDECC3100KA5N00 Equivalent & Substitute Parts

Part Overview

The LDECC3100KA5N00 is a 0.1 µF film capacitor manufactured by KEMET, rated for 50V DC operation in a 1812 (4532 Metric) surface mount package. This component utilizes polyester and polyethylene naphthalate (PEN) metallized-stacked dielectric technology and is qualified to AEC-Q200 automotive standards. The part is active in production with ROHS3 compliance and operates across the temperature range of -55°C to 125°C. Substitute parts are identified when equivalent capacitance and tolerance specifications are maintained while voltage ratings or series designations differ, enabling component selection flexibility for circuit design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LDECC3100KA5N00 are identified based on strict parameter matching within the LDE series film capacitor family. The substitution logic is governed by the following criteria:

Core Matching Parameters (Non-Negotiable):

• Capacitance: 0.1 µF
• Tolerance: ±10%
• Package / Case: 1812 (4532 Metric)
• Dielectric Material: Polyester, Polyethylene Naphthalate (PEN), Metallized - Stacked
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 125°C
• Termination: Solder Pads
• Series: LDE
• Product Status: Active
• Ratings: AEC-Q200
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)

Variable Parameters (Allowed to Differ):

• Voltage Rating - DC
• Voltage Rating - AC
• Base Product Number (LDECC, LDEDC, LDEEC)

Substitute parts maintain identical physical dimensions, thermal characteristics, and automotive compliance certifications. Voltage rating variations allow for circuit design flexibility where higher voltage-rated components can substitute for lower-rated specifications within the same application envelope.

Parameter Comparison

Engineering Selection Recommendations

All three parts—LDECC3100KA5N00, LDEDC3100KA5N00, and LDEEC3100KA5N00—are active production components with identical AEC-Q200 automotive qualification and ROHS3 compliance status. Selection between these parts is determined by circuit voltage requirements:

LDECC3100KA5N00 (50V DC / 40V AC): Select this part when the circuit design specifies a 50V DC operating voltage.

LDEDC3100KA5N00 (63V DC / 40V AC): Select this part when the circuit design specifies a 63V DC operating voltage or when a voltage rating between 50V and 100V is required.

LDEEC3100KA5N00 (100V DC / 63V AC): Select this part when the circuit design specifies a 100V DC operating voltage or when maximum voltage margin is required within the 1812 package envelope.

All parts maintain identical physical dimensions, thermal operating range, dielectric composition, and moisture sensitivity classification. Substitution between these parts is valid when circuit voltage specifications permit the use of higher-rated components.

Frequently Asked Questions (FAQ)

Q: Can LDEEC3100KA5N00 (100V) substitute for LDECC3100KA5N00 (50V)?

A: Yes. The LDEEC3100KA5N00 maintains all physical, thermal, and compliance parameters identical to the LDECC3100KA5N00. The higher voltage rating (100V DC vs. 50V DC) does not create incompatibility in circuits designed for 50V operation. Both parts occupy the same 1812 (4532 Metric) footprint and share identical solder pad termination.

Q: What is the difference between LDECC, LDEDC, and LDEEC base product numbers?

A: The base product number designates the voltage rating tier within the LDE series. LDECC indicates 50V DC rating, LDEDC indicates 63V DC rating, and LDEEC indicates 100V DC rating. All other electrical and mechanical specifications remain constant across these designations for the 0.1 µF, ±10% tolerance configuration in 1812 package.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 qualification and are specified for automotive applications. They maintain identical operating temperature ranges (-55°C to 125°C) and moisture sensitivity levels (MSL 3, 168 hours).

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

A: Yes, provided the circuit voltage specification permits. All three parts share identical 1812 (4532 Metric) package dimensions, solder pad termination, and mounting type (surface mount). PCB layout and reflow profiles remain unchanged between substitutions.

Q: What is the significance of the ±10% tolerance specification?

A: The ±10% tolerance indicates that the actual capacitance value will fall within the range of 0.09 µF to 0.11 µF. This tolerance applies uniformly across all three substitute parts and does not vary with voltage rating.

Q: Is there an inventory consideration when selecting between these parts?

A: Inventory levels differ between the three parts. LDEDC3100KA5N00 maintains the highest stock level (32,929 pcs), followed by LDEEC3100KA5N00 (4,985 pcs) and LDECC3100KA5N00 (701 pcs). Component availability may influence selection when equivalent voltage specifications are acceptable for the application.
