Key Parameters

Substitute Part Grouping Explanation

Substitution of the EEC-RF0H104 is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 100 mF (exact match required)
• Voltage rating: 5.5 V (exact match required)
• Tolerance: -20%, +80% (exact match required)
• Mounting type: Through Hole (exact match required)
• Package style: Radial, Can (exact match required)
• Lead spacing: 0.197" (5.00 mm) (exact match required)
• Lifetime specification: 2000 Hrs @ 85°C (exact match required)

The KW-5R5C104-R from Eaton - Electronics Division meets all mandatory electrical and mechanical criteria for direct substitution. Minor variations in ESR (50 Ohm @ 1kHz versus 40 Ohm) and physical height (0.327" versus 0.374") remain within acceptable tolerance for through-hole applications with standard PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The KW-5R5C104-R is a direct functional equivalent for the obsolete EEC-RF0H104. Selection between these parts should be based on the following factors:

Product Status: The EEC-RF0H104 is obsolete. The KW-5R5C104-R carries active product status from Eaton - Electronics Division, ensuring ongoing availability and supply chain stability.

Compliance & Certifications: Both parts are RoHS compliant. The KW-5R5C104-R meets ROHS3 requirements and is REACH Unaffected, providing enhanced regulatory alignment for current manufacturing standards.

Physical Compatibility: The KW-5R5C104-R is 0.047" (1.20 mm) shorter in seated height than the original part. This dimension reduction is compatible with standard through-hole PCB layouts and does not require design modification.

Electrical Performance: The KW-5R5C104-R exhibits 10 Ohm higher ESR (50 Ohm @ 1kHz versus 40 Ohm). This difference is within typical application tolerances for supercapacitor circuits and does not affect functional equivalence.

Temperature Range: The KW-5R5C104-R extends the lower operating temperature limit to -40°C, providing enhanced performance in cold-environment applications compared to the original -25°C specification.

Frequently Asked Questions (FAQ)

Q: Can the KW-5R5C104-R be used as a direct replacement for the EEC-RF0H104 without PCB modification?

A: Yes. The KW-5R5C104-R maintains identical lead spacing (0.197" / 5.00 mm), diameter (0.531" / 14.60 mm), and termination style (PC Pins, Through Hole). The reduced height (0.327" versus 0.374") does not require PCB layout changes.

Q: What is the significance of the ESR difference between these parts?

A: The KW-5R5C104-R has 50 Ohm ESR @ 1kHz compared to the EEC-RF0H104's 40 Ohm ESR. This 10 Ohm difference represents a 25% increase and may affect transient response characteristics in high-frequency applications. Verify ESR requirements against circuit specifications before selection.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS compliant. The KW-5R5C104-R additionally meets ROHS3 requirements and carries REACH Unaffected status, aligning with current regulatory standards. The EEC-RF0H104, being obsolete, may not meet current compliance requirements for new designs.

Q: Does the extended temperature range of the KW-5R5C104-R affect its suitability?

A: The KW-5R5C104-R operates from -40°C to 85°C, extending the lower limit by 15°C compared to the EEC-RF0H104 (-25°C to 85°C). This provides enhanced performance in cold environments and does not restrict use in applications requiring the original temperature range.

Q: What packaging options are available for these parts?

A: The EEC-RF0H104 is supplied in bulk packaging. The KW-5R5C104-R is also supplied in bulk packaging, maintaining consistency with standard procurement practices for through-hole components.
