Substitute Part Grouping Explanation

Substitution eligibility for the 678D107M040CD3D is determined by the following criteria:

Electrical Parameters (Must Match or Exceed):

• Capacitance: 100 µF (±20% tolerance)
• Voltage Rating: Minimum 40 V (equal or higher voltage rating is acceptable)
• Operating Temperature Range: -55°C ~ 105°C (minimum requirement)
• Lifetime @ 105°C: 3000 Hrs (minimum requirement)
• Polarization: Polar (must be identical)

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: Radial, Can
• Lead Spacing: 0.197" (5.00mm)
• Size / Dimension: 0.394" Dia (10.00mm)

The EEU-FC1H101 meets all substitution criteria with equivalent capacitance, tolerance, operating temperature range, and lifetime specifications. The higher voltage rating (50 V vs. 40 V) and improved ripple current handling provide additional design margin without compromising compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 678D107M040CD3D and EEU-FC1H101 maintain Active product status, ensuring continued availability and manufacturing support. The EEU-FC1H101 provides ROHS3 compliance, whereas the main part is RoHS non-compliant. Selection between these parts depends on regulatory requirements and environmental compliance mandates applicable to the end application. The EEU-FC1H101 carries AEC-Q200 automotive qualification, indicating suitability for automotive-grade applications. The substitute part's reduced seated height (0.492" vs. 0.740") may provide design flexibility in space-constrained applications while maintaining identical lead spacing and diameter specifications.

Frequently Asked Questions (FAQ)

Q: Can the EEU-FC1H101 be used as a direct replacement for the 678D107M040CD3D?

A: Yes. Both parts share identical capacitance (100 µF), tolerance (±20%), operating temperature range (-55°C ~ 105°C), lifetime specification (3000 Hrs @ 105°C), and mechanical dimensions (lead spacing 5.00mm, diameter 10.00mm). The higher voltage rating of the substitute (50 V vs. 40 V) is compatible with circuits designed for 40 V operation.

Q: What is the impact of the different seated heights?

A: The EEU-FC1H101 has a maximum seated height of 0.492" compared to 0.740" for the 678D107M040CD3D. This difference may affect PCB layout and clearance considerations. Verify that the reduced height does not create unintended mechanical or thermal interactions in your specific application.

Q: Are there compliance differences between these parts?

A: The 678D107M040CD3D is RoHS non-compliant, while the EEU-FC1H101 is ROHS3 compliant. Applications subject to RoHS directives or customer specifications requiring RoHS compliance must use the EEU-FC1H101.

Q: How do ripple current ratings compare?

A: The EEU-FC1H101 provides higher ripple current capacity at both low frequency (399.75 mA @ 120 Hz vs. 266 mA) and high frequency (615 mA @ 100 kHz vs. 380 mA). This provides additional thermal margin in applications with significant AC ripple current.

Q: Are both parts suitable for automotive applications?

A: The EEU-FC1H101 carries AEC-Q200 automotive qualification. The 678D107M040CD3D does not list automotive qualification. Applications requiring automotive-grade components should specify the EEU-FC1H101.
