Engineering Selection Recommendations

For direct replacement of EEU-FC1H102L in active designs, EEU-FC1H102 from Panasonic is the primary equivalent. Both parts share identical electrical specifications and AEC-Q200 compliance. The lead spacing difference (0.197" vs 0.295") requires PCB layout verification before substitution.

ELXZ500ELL102MK40S from Chemi-Con provides an upgrade path with extended lifetime (7000 Hrs vs 5000 Hrs) and maintains the original 0.197" lead spacing and 12.50 mm diameter, minimizing PCB layout changes. This part is active and ROHS3 compliant.

ELXY500ELL102ML30S and ELXZ500ELL102ML25S from Chemi-Con offer 8000-hour lifetime ratings with active product status. These parts require PCB layout verification due to different lead spacing (0.295") and package dimensions.

Nichicon parts (UPJ1H102MHD, UPM1H102MHD6, UPS1H102MHD, UPW1H102MHD) are classified as "Not For New Designs." UPS1H102MHD exhibits reduced lifetime (3000 Hrs) and elevated impedance (58 mOhms), making it unsuitable for direct replacement. UPW1H102MHD provides 8000-hour lifetime but is not recommended for new applications.

For automotive applications requiring AEC-Q200 compliance, EEU-FC1H102, ELXZ500ELL102MK40S, and UPM1H102MHD6 meet this requirement.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1H102 replace EEU-FC1H102L directly on the PCB?

A: Electrical specifications are identical. However, lead spacing differs (0.197" vs 0.295"), requiring PCB layout verification. Physical dimensions also differ: EEU-FC1H102 is larger in diameter (16.00 mm vs 12.50 mm) and shorter in height (25.00 mm vs 40.00 mm). Verify clearance and mounting hole spacing before substitution.

Q: What is the difference between the Panasonic FC series and Chemi-Con LXZ/LXY series?

A: All parts meet the same electrical specifications (1000 µF, 50 V, ±20%). Chemi-Con LXZ and LXY series offer extended lifetime ratings (7000-8000 Hrs vs 5000 Hrs). Lead spacing and package dimensions vary. Verify compatibility with your PCB layout.

Q: Why are Nichicon UPS and UPJ series marked "Not For New Designs"?

A: These series are obsolete or end-of-life. UPS1H102MHD specifically has reduced lifetime (3000 Hrs) and higher impedance (58 mOhms) compared to the main part. New designs should use active parts from Panasonic or Chemi-Con.

Q: Is ELXZ500ELL102MK40S a direct replacement for EEU-FC1H102L?

A: Yes, for electrical function. Both have 1000 µF, 50 V, ±20% tolerance, and identical lead spacing (0.197"). ELXZ500ELL102MK40S offers improved lifetime (7000 Hrs vs 5000 Hrs). Height is slightly greater (41.50 mm vs 40.00 mm). Verify vertical clearance in your application.

Q: Can I use UPW1H102MHD as a substitute?

A: UPW1H102MHD meets electrical specifications and offers 8000-hour lifetime. However, it is marked "Not For New Designs." Lead spacing is 0.295" (vs 0.197"), requiring PCB layout verification. Use only if no active alternatives are available.

Q: What does "Lead Spacing" mean for through-hole capacitors?

A: Lead spacing is the distance between the two radial leads. EEU-FC1H102L has 0.197" (5.00 mm) spacing. Substitutes with 0.295" (7.50 mm) spacing require different PCB hole patterns and cannot be used without PCB modification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant. UPM1H102MHD6 is REACH Affected; all others are REACH Unaffected.
