Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-FC1H100B is determined by the following critical parameters:

• Capacitance: 10 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)

Substitute parts must maintain identical electrical specifications and physical form factor compatibility. Variations in lead spacing, case diameter, and height are acceptable provided the component fits within the PCB layout constraints of the original design. Lifetime at temperature and ripple current ratings may vary between substitutes without affecting functional equivalence, as these represent performance enhancements or different design margins.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: EEU-FC1H100LB

The EEU-FC1H100LB is the direct equivalent from Panasonic with active product status. It maintains identical electrical specifications (10 µF, 50 V, ±20%, 1000 Hrs @ 105°C) and meets AEC-Q200 automotive ratings. The component is available in Cut Tape packaging with 13,785 units in stock. Physical dimensions differ slightly (larger case diameter and height), requiring PCB layout verification before implementation.

Secondary Recommendation: EEU-FC1H100LH

The EEU-FC1H100LH is an active Panasonic part with identical electrical specifications and AEC-Q200 compliance. Lead spacing differs at 0.098" (2.50mm) compared to the original 0.197" (5.00mm), necessitating PCB footprint evaluation. This part is available in Cut Tape packaging with 13,930 units in stock.

Alternative Recommendation: EEU-FC1H100L

The EEU-FC1H100L is an active Panasonic part with identical electrical specifications and AEC-Q200 compliance. Lead spacing is 0.079" (2.00mm), requiring PCB footprint verification. This part is available in Bulk packaging with 4,391 units in stock.

Cross-Manufacturer Alternatives: Nichicon UPJ1H100MDD, UPM1H100MDD, UPS1H100MDD, UPV1H100MFD

Nichicon parts maintain identical capacitance, voltage, tolerance, and operating temperature range. These components feature extended lifetime ratings (2000 Hrs or 5000 Hrs @ 105°C) and are currently obsolete. UPM1H100MDD carries AEC-Q200 automotive certification. All Nichicon alternatives use 0.079" (2.00mm) lead spacing and require PCB layout verification. Inventory availability is limited (790 to 9,836 units).

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1H100LB be used as a direct replacement for EEU-FC1H100B?

A: Yes. Both parts share identical electrical specifications (10 µF, 50 V, ±20%, 1000 Hrs @ 105°C, -55°C ~ 105°C operating range) and AEC-Q200 automotive compliance. Physical dimensions differ; verify PCB layout accommodates the larger case diameter (0.197" vs 0.157") and height (0.571" vs 0.472").

Q: What is the significance of lead spacing differences?

A: Lead spacing determines PCB footprint compatibility. The original EEU-FC1H100B uses 0.197" (5.00mm) spacing. Alternatives with 0.079" (2.00mm) or 0.098" (2.50mm) spacing require PCB redesign or use of adapter solutions. Verify hole pattern compatibility before component selection.

Q: Are Nichicon parts suitable replacements?

A: Nichicon UPJ1H100MDD, UPM1H100MDD, UPS1H100MDD, and UPV1H100MFD maintain identical capacitance, voltage, tolerance, and operating temperature specifications. All are currently obsolete. UPM1H100MDD carries AEC-Q200 automotive certification. Lead spacing is 0.079" (2.00mm), requiring PCB footprint evaluation. Extended lifetime ratings (2000 Hrs or 5000 Hrs @ 105°C) represent performance enhancements over the original 1000 Hrs specification.

Q: What packaging options are available?

A: Panasonic active alternatives are available in Cut Tape (CT) and Bulk packaging. EEU-FC1H100LB offers 13,785 units in Cut Tape. EEU-FC1H100LH provides 13,930 units in Cut Tape. EEU-FC1H100L supplies 4,391 units in Bulk. Nichicon parts are available in Bulk packaging only with limited inventory (790 to 9,836 units).

Q: Does product status affect substitution eligibility?

A: Product status indicates availability and supply chain continuity. Active parts (EEU-FC1H100LB, EEU-FC1H100LH, EEU-FC1H100L) are recommended for new designs and ongoing production. Obsolete parts (Nichicon series) may have limited future availability and should be evaluated for long-term supply chain risk.

Q: Are there compliance or certification differences?

A: EEU-FC1H100B, EEU-FC1H100LB, EEU-FC1H100LH, and EEU-FC1H100L all meet AEC-Q200 automotive specifications and are ROHS3 compliant. UPM1H100MDD carries AEC-Q200 certification; other Nichicon parts do not list automotive ratings. All parts are REACH Unaffected and classified as EAR99 for export control purposes.
