Substitute Part Grouping Explanation

Substitution for the EEF-CD0D101R is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 100 µF (exact match required)
• Voltage Rating: 2 V (exact match required)
• Tolerance: ±20% (exact match required)
• Dielectric Type: Aluminum Polymer (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Lifetime Rating: 1000 Hrs @ 105°C (exact match required)

The ECASD40D107M016K00 manufactured by Murata Electronics meets all substitution criteria. While ESR differs slightly (16 mOhm versus 18 mOhm), this represents an improvement in performance characteristics and does not disqualify the part as a functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ECASD40D107M016K00 is a direct functional equivalent for the EEF-CD0D101R. Both components are classified as obsolete, indicating end-of-life status from their respective manufacturers. The Murata part carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for applications subject to these requirements. The lower ESR specification of the Murata substitute (16 mOhm versus 18 mOhm) represents equivalent or superior performance in thermal and ripple current handling characteristics. Identical package geometry, mounting type, and thermal ratings ensure mechanical and electrical compatibility in existing PCB designs without layout modification.
