Substitute Part Grouping Explanation

Substitution of the EEF-UD0G151ER is determined by the following critical parameters:

• Capacitance Value: 150 µF (exact match required)
• Voltage Rating: 4 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)
• ESR: 15 mOhm (exact match required for electrical performance)
• Type: Aluminum Polymer (exact match required for application compatibility)

The EEF-CX0G151R meets all substitution criteria as a direct equivalent, with identical electrical specifications and package dimensions. This part is currently in active production status.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0G151R is the direct substitute for the obsolete EEF-UD0G151ER. Both parts share identical core electrical specifications (150 µF, 4 V, ±20%, 15 mOhm ESR) and package geometry (2917 / 7343 Metric), ensuring direct PCB compatibility without layout modifications.

The EEF-CX0G151R offers enhanced performance characteristics including extended lifetime (2000 Hrs vs. 1000 Hrs @ 105°C), wider operating temperature range (-55°C to 105°C vs. -40°C to 105°C), and higher ripple current capability (5.1 A vs. 3 A @ 100 kHz). The substitute part is currently in active production with ROHS3 compliance and REACH unaffected status, supporting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0G151R be used as a direct replacement for the EEF-UD0G151ER?

A: Yes. Both parts are identical in capacitance (150 µF), voltage rating (4 V), tolerance (±20%), ESR (15 mOhm), and package dimensions (2917 / 7343 Metric). No PCB modifications are required.

Q: What are the physical differences between these parts?

A: The EEF-CX0G151R has a lower seated height (1.90 mm vs. 3.00 mm). This reduced height may provide design flexibility but does not affect electrical compatibility or PCB footprint.

Q: Does the EEF-CX0G151R meet current compliance standards?

A: Yes. The EEF-CX0G151R is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Are there performance advantages to using the EEF-CX0G151R?

A: The substitute part provides extended operational lifetime (2000 Hrs vs. 1000 Hrs @ 105°C), expanded temperature range (-55°C to 105°C vs. -40°C to 105°C), and increased ripple current handling (5.1 A vs. 3 A @ 100 kHz).

Q: What is the packaging format for the EEF-CX0G151R?

A: The substitute part is supplied in Tape & Reel (TR) format, standard for high-volume surface-mount assembly operations.
