EEU-FC1J102 Equivalent & Substitute Parts

Part Overview

The EEU-FC1J102 is a 1000 µF, 63 V aluminum electrolytic capacitor in radial configuration manufactured by Panasonic Electronic Components. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The capacitor is rated for 5000 hours at 105°C and meets AEC-Q200 automotive qualification standards. Substitute parts must maintain electrical equivalence across capacitance, voltage rating, and thermal performance while accommodating mechanical variations within acceptable design tolerances.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following electrical and mechanical parameters:

Electrical Equivalence Requirements:

Capacitance: 1000 µF (fixed)
Tolerance: ±20% (fixed)
Voltage Rating: 63 V (fixed)
Operating Temperature: -55°C to 105°C (fixed)
Polarization: Polar (fixed)

Mechanical Compatibility Requirements:

Mounting Type: Through Hole (fixed)
Package / Case: Radial, Can (fixed)
Lead Spacing: 0.295" (7.50 mm) (fixed)
Size / Dimension: 0.630" Dia (16.00 mm) (fixed, with tolerance for height variation)

Thermal Performance Consideration:

Lifetime @ 105°C: 5000 hours minimum (parts with 8000 hours provide extended reliability)

Substitute parts meeting all electrical and mechanical parameters are classified as direct equivalents. Parts with extended thermal ratings (8000 hours) are classified as upgrades. Parts with reduced thermal ratings (3000 hours) are classified as downgrades and require design review.

Engineering Selection Recommendations

Primary Equivalent (Active Status): EEU-FC1J102U (Panasonic) is the direct active equivalent. It maintains identical electrical specifications and AEC-Q200 certification. The reduced height (31.50 mm vs. 35.50 mm) provides improved PCB layout flexibility while preserving all functional parameters.

Upgrade Options (Extended Thermal Life): ELXZ630ELL102ML35S (Chemi-Con) and ELXY630ELL102ML40S (Chemi-Con) provide 8000-hour thermal ratings at 105°C, extending component life by 60% compared to the original specification. Both maintain AEC-Q200 certification and are actively produced. Height variations (36.50 mm and 41.50 mm respectively) require PCB clearance verification.

Legacy Substitutes (Not For New Designs): Nichicon parts (UPJ1J102MHD, UPJ1J102MHD6, UPM1J102MHD, UPM1J102MHD6, UPW1J102MHD6) and UPS1J102MHD are classified as not for new designs. These parts are suitable only for maintenance and repair of existing equipment. UPS1J102MHD carries a reduced 3000-hour thermal rating and requires design review before application.

Compliance Considerations: All substitute parts are ROHS3 compliant. UPM1J102MHD and UPM1J102MHD6 are REACH Affected; UPM1J102MHD carries REACH Affected status requiring supply chain verification. All other parts are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1J102U replace EEU-FC1J102 directly? A: Yes. EEU-FC1J102U is electrically and mechanically equivalent with identical 1000 µF, 63 V, ±20% specifications and 5000-hour thermal rating. The reduced height (31.50 mm) requires only PCB clearance confirmation.

Q: What is the difference between 5000-hour and 8000-hour rated parts? A: Thermal life rating indicates the expected operational duration at 105°C before capacitance degradation reaches 20% of initial value. 8000-hour parts provide extended reliability for applications requiring longer service intervals or higher ambient temperatures.

Q: Are Chemi-Con ELXY and ELXZ series parts suitable for automotive applications? A: Yes. Both ELXY630ELL102ML40S and ELXZ630ELL102ML35S carry AEC-Q200 certification and are specified for automotive applications. They are actively produced and recommended for new designs requiring extended thermal performance.

Q: Why are Nichicon UPJ and UPM series marked "Not For New Designs"? A: These parts remain available for maintenance and repair of existing equipment but are not recommended for new product development. Panasonic and Chemi-Con active alternatives provide equivalent or superior performance with ongoing manufacturer support.

Q: Can UPS1J102MHD be used as a substitute? A: UPS1J102MHD meets mechanical and electrical specifications but carries a reduced 3000-hour thermal rating compared to the 5000-hour original specification. Application requires design review to confirm thermal margin adequacy for the intended duty cycle.

Q: What mechanical dimensions must be verified before substitution? A: Lead spacing (0.295" / 7.50 mm) and diameter (0.630" / 16.00 mm) are fixed across all equivalents. Height varies from 31.50 mm to 42.00 mm depending on part selection. PCB layout and clearance to adjacent components must be verified for parts with height exceeding 35.50 mm.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant. UPM1J102MHD and UPM1J102MHD6 are REACH Affected; all other parts are REACH Unaffected.
