Substitute Part Grouping Explanation

The EEF-CX0J181R qualifies as a direct substitute for the EEF-UE0J181CE based on the following alignment of critical electrical and mechanical parameters:

• Capacitance: Both parts are rated at 180 µF
• Voltage Rating: Both parts are rated at 6.3 V
• Tolerance: Both parts maintain ±20% tolerance
• Package / Case: Both use the 2917 (7343 Metric) surface mount package
• Mounting Type: Both are surface mount components
• Dielectric Type: Both are aluminum polymer capacitors

The EEF-CX0J181R represents an active product with enhanced specifications, including improved ESR (15 mOhm), extended lifetime (2000 Hrs @ 105°C), and expanded operating temperature range (-55°C ~ 105°C).

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0J181R is the appropriate substitute for the obsolete EEF-UE0J181CE. Both parts share identical electrical specifications (180 µF, 6.3 V, ±20% tolerance) and mechanical compatibility (2917 package, surface mount configuration). The substitute part offers additional advantages: ROHS3 compliance and REACH unaffected status ensure regulatory alignment with current environmental standards. The EEF-CX0J181R is currently in active production with established supply availability, making it the suitable choice for new designs and component replacement in existing applications.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0J181R be used as a direct replacement for the EEF-UE0J181CE?

A: Yes. Both parts share identical capacitance (180 µF), voltage rating (6.3 V), tolerance (±20%), and package configuration (2917 surface mount). Electrical and mechanical compatibility is confirmed.

Q: What is the difference in physical height between these parts?

A: The EEF-UE0J181CE has a seated height of 0.169" (4.30mm), while the EEF-CX0J181R has a seated height of 0.075" (1.90mm). The substitute part is significantly lower profile, which may provide layout advantages in space-constrained applications.

Q: Does the substitute part meet current environmental compliance requirements?

A: Yes. The EEF-CX0J181R is ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The main part specifications do not include these compliance certifications.

Q: Are there differences in operating temperature range?

A: The EEF-CX0J181R operates from -55°C to 105°C, compared to the EEF-UE0J181CE range of -40°C to 105°C. The substitute part provides extended low-temperature capability.

Q: What is the lifetime difference between these capacitors?

A: The EEF-UE0J181CE is rated for 1000 hours at 105°C, while the EEF-CX0J181R is rated for 2000 hours at 105°C. The substitute part offers double the thermal lifetime rating.

Q: Is the EEF-CX0J181R currently available?

A: Yes. The EEF-CX0J181R is an active product with established inventory. The EEF-UE0J181CE is obsolete and no longer in production.
