EEC-RF0H105 Equivalent & Substitute Parts

Part Overview

The EEC-RF0H105 is a 1 F (EDLC) supercapacitor manufactured by Panasonic Electronic Components, rated for 5.5 V with radial through-hole termination. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The part delivers 2000 hours of operational lifetime at 85°C with 40Ohm equivalent series resistance and is RoHS compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EEC-RF0H105 is determined by strict alignment of the following electrical and mechanical parameters:

• Capacitance value: 1 F (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 configuration: Radial (exact match required)
• Lead spacing: 0.197" (5.00mm) (exact match required)
• Lifetime specification: 2000 Hrs @ 85°C (exact match required)

The KW-5R5C105-R from Eaton - Electronics Division meets all substitution criteria. This part maintains identical electrical specifications and mechanical compatibility while offering improved ESR performance (30Ohm @ 1kHz versus 40Ohm) and extended operating temperature range (-40°C ~ 85°C versus -25°C ~ 85°C).

Engineering Selection Recommendations

The KW-5R5C105-R is the direct functional equivalent for the obsolete EEC-RF0H105. Selection of this substitute is supported by:

• Active product status with confirmed availability (5200 pcs in stock)
• Full compliance with ROHS3 standards, exceeding the RoHS compliance of the original part
• Identical electrical specifications (1 F, 5.5 V, -20%/+80% tolerance, 2000 Hrs @ 85°C)
• Mechanical compatibility with identical lead spacing (0.197" / 5.00mm) and equivalent package dimensions
• Improved ESR performance (30Ohm @ 1kHz) and extended low-temperature operating range (-40°C minimum)

Frequently Asked Questions (FAQ)

Q: Can the KW-5R5C105-R be used as a direct replacement for the EEC-RF0H105?

A: Yes. Both parts share identical capacitance (1 F), voltage rating (5.5 V), tolerance (-20%, +80%), lead spacing (0.197" / 5.00mm), and lifetime specification (2000 Hrs @ 85°C). Through-hole radial mounting is identical, enabling direct PCB compatibility.

Q: What are the differences between these parts?

A: The KW-5R5C105-R offers three advantages: lower ESR (30Ohm @ 1kHz versus 40Ohm), extended low-temperature operation (-40°C minimum versus -25°C minimum), and active product status with higher inventory availability. The Eaton part is slightly shorter (0.348" versus 0.374" seated height).

Q: Are there compliance differences?

A: The KW-5R5C105-R meets ROHS3 compliance, while the EEC-RF0H105 meets RoHS compliance. ROHS3 represents a more current regulatory standard. Both parts carry EAR99 ECCN classification.

Q: Does the lower ESR of the substitute affect circuit performance?

A: Lower ESR improves transient response and reduces heat generation during charge/discharge cycles. This represents a performance enhancement for applications sensitive to impedance characteristics.

Q: Are the physical dimensions compatible with existing PCB layouts?

A: Yes. Both parts maintain 0.197" (5.00mm) lead spacing and 0.846" (21.50mm) diameter. The Eaton part is 0.026" (0.65mm) shorter in seated height, which does not affect through-hole mounting compatibility.
