Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 107KFM200M is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 100 µF (exact match required)
• Tolerance: ±20% (equal or tighter tolerance acceptable)
• Polarization: Polar (must match)
• Package Type: Radial, Can (must match)
• Mounting Type: Through Hole (must match)
• Lead Spacing: 0.295" (7.50mm) (must match for PCB fit)
• Operating Temperature Range: -40°C ~ 105°C (must support full range)
• Lifetime @ 105°C: 10000 Hrs minimum (must meet or exceed)

Acceptable Variation Parameters:

• Voltage Rating: 200 V minimum (higher ratings are acceptable as they provide additional safety margin)
• Ripple Current: Higher values acceptable (indicates improved performance capability)
• ESR: Lower values acceptable (indicates improved performance)
• Physical Height: Minor variations acceptable if within PCB clearance constraints

The substitute part UCS2E101MHD from Nichicon meets all mandatory matching criteria and provides an upgraded voltage rating of 250 V with enhanced ripple current performance.

Parameter Comparison

Engineering Selection Recommendations

The UCS2E101MHD from Nichicon is a direct substitute for the 107KFM200M based on the following engineering criteria:

Electrical Compatibility: All core electrical parameters match or exceed the original specification. The 100 µF capacitance and ±20% tolerance are identical. The 250 V voltage rating provides a 50 V margin above the 200 V requirement, enhancing circuit reliability. Enhanced ripple current ratings (765 mA @ 120 Hz and 1.53 A @ 100 kHz compared to 465 mA and 930 mA respectively) indicate superior performance capability in high-frequency and high-ripple applications.

Mechanical Compatibility: Lead spacing, package type, mounting configuration, and can diameter are identical. The seated height difference of 0.02" (0.5mm) is negligible and does not affect PCB assembly or clearance in standard applications.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH Unaffected status, satisfying environmental and regulatory requirements.

Operational Reliability: Both components support the full -40°C to 105°C operating temperature range and maintain 10000 hours lifetime at 105°C, ensuring equivalent long-term reliability.

Frequently Asked Questions (FAQ)

Q: Can the UCS2E101MHD replace the 107KFM200M in any application?

A: The UCS2E101MHD is electrically and mechanically compatible with the 107KFM200M for applications requiring 100 µF capacitance at 200 V or lower. The higher 250 V rating and enhanced ripple current performance make it suitable for the same circuit applications. Verify PCB clearance for the 0.02" height difference in space-constrained designs.

Q: What is the significance of the voltage rating upgrade from 200 V to 250 V?

A: The 250 V rating provides a 25% safety margin above the 200 V requirement. This upgrade reduces stress on the dielectric material, potentially extending operational life and improving reliability in circuits operating near the maximum voltage specification.

Q: Are the ripple current improvements significant?

A: Yes. The UCS2E101MHD provides 64% higher ripple current at 120 Hz (765 mA vs. 465 mA) and 65% higher ripple current at 100 kHz (1.53 A vs. 930 mA). These improvements indicate enhanced thermal performance and suitability for applications with higher AC current demands.

Q: Do the components have identical physical dimensions?

A: The components share identical lead spacing (0.295" / 7.50mm), can diameter (0.630" / 16.00mm), and package type (Radial, Can). The seated height differs by 0.02" (0.5mm), with the UCS2E101MHD being slightly shorter. This difference is negligible for standard PCB layouts.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the 107KFM200M and UCS2E101MHD are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What is the ESR difference between the two parts?

A: The 107KFM200M specifies 2.487 Ohm ESR @ 120 Hz. The UCS2E101MHD ESR specification is not provided in the available data. For applications where ESR is a critical parameter, direct measurement or manufacturer consultation is necessary.

Q: Can these capacitors be used interchangeably in existing designs?

A: Yes, for PCB designs with standard clearance. The identical lead spacing and package type ensure direct PCB compatibility. Verify that the 0.02" height difference does not conflict with component placement or enclosure constraints in your specific design.
