Substitute Part Grouping Explanation

Substitution of the ECASD40D337M006KA0 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Capacitance value: 330 µF (±20% tolerance)
• Package / Case: 2917 (7343 Metric)
• Mounting type: Surface Mount
• Physical dimensions: 0.287" L x 0.169" W (7.30mm x 4.30mm)
• ESR: 6 mOhm
• Operating temperature range: -40°C ~ 105°C
• Lifetime rating: 2000 Hrs @ 105°C
• Ripple current capability: 3 A @ 100 kHz

Allowable Variation:

• Voltage rating: Substitute parts must equal or exceed the rated voltage of the original component. A higher voltage rating provides additional design margin and operational safety.

The ECASD40E337M006KA0 meets all mandatory equivalence criteria and provides a higher voltage rating (2.5 V versus 2 V), making it a direct substitute suitable for applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The ECASD40E337M006KA0 is the direct substitute for the obsolete ECASD40D337M006KA0. Selection of this substitute is based on the following engineering factors:

Product Status: The original part is classified as obsolete, while the substitute remains in active production status. This ensures long-term availability and supply chain continuity for new designs and production runs.

Electrical Equivalence: Both parts maintain identical capacitance (330 µF), ESR (6 mOhm), ripple current capability (3 A @ 100 kHz), and thermal lifetime rating (2000 Hrs @ 105°C). The substitute's higher voltage rating (2.5 V) provides additional operational margin without compromising performance in applications designed for 2 V operation.

Compliance and Certifications: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Physical and Mechanical Compatibility: Identical package dimensions (2917 / 7343 Metric), mounting type (Surface Mount), and land pattern ensure direct PCB compatibility without layout modifications.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume production environments. The original part's Cut Tape (CT) & Digi-Reel® packaging is typical for lower-volume or prototype applications.

Frequently Asked Questions (FAQ)

Q: Can the ECASD40E337M006KA0 be used as a direct replacement for the ECASD40D337M006KA0?

A: Yes. The substitute part maintains identical electrical specifications (330 µF capacitance, 6 mOhm ESR, 3 A ripple current, 2000 Hrs @ 105°C lifetime) and physical dimensions (2917 package, 7.30mm x 4.30mm x 2.00mm). The higher voltage rating (2.5 V versus 2 V) provides additional design margin and is fully compatible with applications designed for the original 2 V part.

Q: What is the primary difference between these two parts?

A: The ECASD40E337M006KA0 has a rated voltage of 2.5 V compared to the original part's 2 V rating. Additionally, the substitute is in active production status, whereas the original is obsolete. All other electrical and mechanical parameters are identical.

Q: Are there any PCB layout changes required when substituting the ECASD40E337M006KA0?

A: No. Both parts use the identical 2917 (7343 Metric) package with matching physical dimensions and land pattern. PCB layouts require no modification.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging?

A: Cut Tape (CT) & Digi-Reel® packaging is typically used for lower-volume orders and prototype applications, where components are supplied in smaller quantities on cut tape segments. Tape & Reel (TR) packaging is standard for high-volume production runs, where components are supplied on continuous reels for automated assembly equipment. Both packaging formats contain identical components; the difference is in supply format and quantity per reel.

Q: Does the higher voltage rating of the substitute affect circuit performance?

A: No. A higher voltage rating does not alter the capacitance value, ESR, ripple current capability, or thermal characteristics. The substitute operates identically to the original part in all applications designed for 2 V operation. The higher voltage rating simply provides additional safety margin and extends the operational envelope.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the ECASD40D337M006KA0 and ECASD40E337M006KA0 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have an MSL rating of 3 (168 Hours), indicating that the components must be stored in controlled humidity conditions and used within 168 hours of exposure to ambient moisture after packaging removal.
