Substitute Part Grouping Explanation

The ECASD41C336M040KA0 can be substituted with the ECASD41E336M040KA0 based on the following criteria:

Matching Parameters:

• Capacitance: 33 µF (identical)
• Tolerance: ±20% (identical)
• Type: Aluminum Polymer (identical)
• ESR: 40 mOhm (identical)
• Package: 2917 (7343 Metric) (identical)
• Mounting Type: Surface Mount (identical)
• Operating Temperature Range: -40°C to 105°C (identical)
• Lifetime @ Temperature: 1000 Hrs @ 105°C (identical)
• Ripple Current @ 100 kHz: 1.6 A (identical)

Differing Parameter:

• Voltage Rating: 16 V (main part) vs. 25 V (substitute)

The substitute part operates at a higher voltage rating, which maintains backward compatibility in applications designed for the original 16 V specification.

Parameter Comparison

Engineering Selection Recommendations

The ECASD41E336M040KA0 is the designated manufacturer-recommended substitute for the obsolete ECASD41C336M040KA0. Both parts maintain identical electrical and mechanical specifications with the exception of voltage rating. The substitute operates at 25 V, providing increased voltage margin over the original 16 V specification. Both parts carry ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility. The substitute part maintains active product status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the ECASD41E336M040KA0 be used as a direct replacement for the ECASD41C336M040KA0?

A: Yes. The substitute part shares identical capacitance, tolerance, ESR, package dimensions, and thermal characteristics. The higher voltage rating of 25 V provides additional design margin in applications originally specified for 16 V operation.

Q: Are there any physical differences between these parts?

A: No. Both parts use the 2917 (7343 Metric) surface mount package with identical dimensions of 7.30mm L x 4.30mm W x 2.00mm H. PCB land patterns and mounting procedures are identical.

Q: What is the significance of the voltage rating difference?

A: The substitute part's 25 V rating exceeds the original 16 V specification. This higher rating does not affect performance in 16 V applications and provides additional safety margin. No circuit modifications are required.

Q: Are both parts RoHS compliant?

A: Yes. Both the ECASD41C336M040KA0 and ECASD41E336M040KA0 are ROHS3 compliant and REACH unaffected.

Q: What is the packaging difference between the two parts?

A: The original part is supplied in Tape & Reel (TR) packaging. The substitute is available in Cut Tape (CT) & Digi-Reel® packaging. Both packaging formats are suitable for automated assembly processes.
