Equivalent & Substitute Parts for ECS-F1AE106K

Part Overview

The ECS-F1AE106K is a 10 µF conformal coated tantalum capacitor rated at 10 V with radial through-hole mounting, manufactured by Panasonic Electronic Components. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Conformal coated tantalum capacitors in this specification are used in applications requiring reliable energy storage with environmental protection. The obsolete status of the ECS-F1AE106K necessitates sourcing equivalent components that maintain electrical performance and mechanical compatibility within the constraints of the original design.

Substitute Part Grouping Explanation

Substitution for the ECS-F1AE106K is determined by strict equivalence across the following parameters:

• Capacitance Value: 10 µF (exact match required)
• Voltage Rating: 10 V (minimum requirement; higher ratings are acceptable)
• Type: Conformal Coated Tantalum (functional requirement)
• Mounting Configuration: Through Hole Radial (mechanical requirement)
• Lead Spacing: 0.098" (2.50mm) or 0.100" (2.54mm) standard spacing (PCB compatibility)

The substitute parts identified—T350C106K010AS (KEMET) and TAP106K010SCS (KYOCERA AVX)—meet these core substitution criteria. Both components provide the required 10 µF capacitance at 10 V with conformal coating and radial through-hole mounting. Tolerance improvements (±10% versus ±20%) and enhanced operating temperature ranges represent functional advantages over the obsolete original part.

Engineering Selection Recommendations

TAP106K010SCS (KYOCERA AVX) is the preferred substitute for the ECS-F1AE106K. This component maintains exact lead spacing compatibility (0.098" / 2.50mm), ensuring direct PCB fit without layout modification. The TAP106K010SCS is ROHS3 compliant, providing regulatory advantage for new designs and systems subject to environmental standards. The component is currently in active production with confirmed inventory availability.

T350C106K010AS (KEMET) serves as a secondary equivalent option. This part meets all core electrical and mechanical substitution criteria with improved tolerance (±10%) and extended operating temperature range (-55°C to 125°C). The lead spacing of 0.100" (2.54mm) represents a minor mechanical variance from the original 0.098" (2.50mm) specification; PCB compatibility depends on pad layout tolerance. This component is active and in stock.

Both substitutes provide superior tolerance specifications and extended temperature performance compared to the obsolete original part, supporting long-term system reliability.

Frequently Asked Questions (FAQ)

Q: Can the T350C106K010AS be used if the PCB is designed for 0.098" lead spacing?

A: The T350C106K010AS has 0.100" (2.54mm) lead spacing versus the original 0.098" (2.50mm). Compatibility depends on PCB pad tolerance and hole sizing. Standard PCB manufacturing tolerances typically accommodate this 0.002" variance, but verification against your specific PCB design is necessary.

Q: What is the functional difference between ±20% and ±10% tolerance?

A: The original ECS-F1AE106K allows capacitance variation between 8 µF and 12 µF. The substitute parts (T350C106K010AS and TAP106K010SCS) limit variation to 9 µF and 11 µF. This tighter tolerance improves circuit performance predictability, particularly in timing-sensitive or filtering applications.

Q: Are the substitute parts conformal coated?

A: Yes. Both T350C106K010AS and TAP106K010SCS are conformal coated tantalum capacitors, maintaining the environmental protection characteristics of the original ECS-F1AE106K.

Q: What is the significance of the 5 Ohm ESR specification in the substitutes?

A: ESR (Equivalent Series Resistance) of 5 Ohm is specified for both substitute parts. This parameter affects ripple current handling and transient response. The original part does not specify ESR; the substitute specifications provide defined performance characteristics for circuit analysis.

Q: Is RoHS compliance required for my application?

A: The ECS-F1AE106K is RoHS non-compliant. If your system or market requires RoHS compliance, the TAP106K010SCS (ROHS3 compliant) is the appropriate selection. The T350C106K010AS remains non-compliant.

Q: Can these parts be used in high-temperature applications?

A: Both substitutes support -55°C to 125°C operation, extending the original part's -55°C to 105°C range. This provides additional thermal margin for applications approaching the original temperature limits.
