Substitute Part Grouping Explanation

Substitution of the EEF-UD0D331CR is determined by the following critical parameters:

• Capacitance Value: 330 µF (exact match required)
• Voltage Rating: 2 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• Component Type: Aluminum Polymer Capacitor (exact match required)

The substitute part EEF-CX0D331R meets all critical substitution criteria. Both parts share identical capacitance, voltage rating, tolerance, package dimensions, and mounting configuration. The substitute represents an active product from the same manufacturer with enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0D331R is the direct substitute for the obsolete EEF-UD0D331CR. Both parts are manufactured by Panasonic Electronic Components and share identical electrical specifications and physical package dimensions required for PCB compatibility.

The EEF-CX0D331R carries active product status, ensuring ongoing availability and supply chain support. The substitute part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

The EEF-CX0D331R demonstrates improved performance characteristics compared to the main part, including extended lifetime (2000 hours versus 1000 hours at 105°C), lower operating temperature floor (-55°C versus -40°C), and specified ESR of 15 mOhm. The substitute maintains a lower seated height (1.90mm versus 3.00mm), which may provide additional design flexibility in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0D331R be used as a direct replacement for the EEF-UD0D331CR?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (2 V), tolerance (±20%), package configuration (2917 / 7343 Metric), and mounting type (surface mount). PCB footprints and land patterns are compatible.

Q: What is the primary reason for substitution?

A: The EEF-UD0D331CR has reached obsolete product status. The EEF-CX0D331R is an active product from the same manufacturer with equivalent electrical and mechanical specifications.

Q: Are there any height differences between these parts?

A: Yes. The EEF-CX0D331R has a maximum seated height of 0.075" (1.90mm), while the EEF-UD0D331CR is 0.118" (3.00mm). The substitute part is lower profile and may be advantageous in applications with height constraints.

Q: Does the substitute part meet current regulatory standards?

A: Yes. The EEF-CX0D331R is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the difference in lifetime specifications?

A: The EEF-CX0D331R provides 2000 hours at 105°C compared to 1000 hours for the EEF-UD0D331CR. This represents extended operational life under elevated temperature conditions.

Q: Are the operating temperature ranges different?

A: Yes. The EEF-CX0D331R operates from -55°C to 105°C, while the EEF-UD0D331CR operates from -40°C to 105°C. The substitute part supports a wider lower temperature range.
