Key Parameters

Substitute Part Grouping Explanation

Substitution of the EEF-CD0D151XR is determined by the following critical parameters:

• Capacitance Value: Must remain 150 µF (±20% tolerance acceptable)
• Package / Case: Must be 2917 (7343 Metric) for PCB footprint compatibility
• Mounting Type: Must be Surface Mount
• Physical Dimensions: Must match 0.287" L x 0.169" W (7.30mm x 4.30mm) and height 0.075" (1.90mm) maximum
• Voltage Rating: Must be equal to or greater than 2 V for safe operation in the original circuit

The EEF-CX0G151R qualifies as a direct substitute based on matching capacitance, identical package dimensions, and compatible voltage rating. The substitute part offers enhanced performance through higher voltage rating (4 V), improved ESR specification (15 mOhm), and extended lifetime (2000 Hrs @ 105°C).

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0G151R is the appropriate substitute for the obsolete EEF-CD0D151XR based on the following engineering criteria:

Product Status: The EEF-CX0G151R maintains active production status with Panasonic Electronic Components, ensuring long-term availability and supply chain stability compared to the obsolete EEF-CD0D151XR.

Electrical Compatibility: The substitute part maintains identical capacitance (150 µF) and tolerance (±20%), with a higher voltage rating (4 V versus 2 V). This higher voltage rating provides additional design margin and is fully compatible with circuits designed for the original 2 V specification.

Physical Compatibility: Both parts share identical package dimensions (2917 / 7343 Metric), surface mount configuration, and PCB footprint requirements, enabling direct board-level substitution without layout modifications.

Performance Enhancement: The EEF-CX0G151R provides measurable performance improvements including specified ESR of 15 mOhm, doubled operational lifetime (2000 Hrs @ 105°C versus 1000 Hrs), and extended lower operating temperature limit (-55°C versus -40°C).

Compliance: The substitute part is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0G151R be used as a direct replacement for the EEF-CD0D151XR on existing PCBs?

A: Yes. Both parts use identical 2917 (7343 Metric) surface mount packages with matching footprint dimensions (0.287" L x 0.169" W, 0.075" height maximum). No PCB layout modifications are required.

Q: What is the significance of the higher 4 V rating on the substitute part?

A: The EEF-CX0G151R's 4 V rating exceeds the original 2 V specification, providing additional voltage margin. Circuits designed for 2 V operation remain fully compatible, as the substitute part safely operates at lower voltages with improved reliability.

Q: Are there any electrical performance differences between these parts?

A: The EEF-CX0G151R provides specified ESR of 15 mOhm, whereas the original part does not specify ESR. The substitute also offers doubled lifetime rating (2000 Hrs @ 105°C versus 1000 Hrs) and extended lower temperature operation (-55°C versus -40°C).

Q: Why is the EEF-CD0D151XR classified as obsolete?

A: The EEF-CD0D151XR belongs to the SP-Cap CD series, which has been superseded by newer Panasonic polymer capacitor lines offering improved performance and extended operational specifications. The EEF-CX0G151R from the SP-Cap CX series represents the current active product line.

Q: What packaging options are available for the EEF-CX0G151R?

A: The EEF-CX0G151R is supplied in Tape & Reel (TR) packaging, standard for high-volume surface mount assembly operations.

Q: Are there any compliance or regulatory considerations for this substitution?

A: The EEF-CX0G151R is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. Both parts carry ECCN EAR99 and HTSUS 8532.22.0020 classifications.
