ECS-F1AE336K Equivalent & Substitute Parts

Part Overview

The ECS-F1AE336K is a 33 µF conformal coated tantalum capacitor rated at 10 V with radial through-hole mounting, manufactured by Panasonic Electronic Components as part of the EF series. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. Substitute parts must maintain the same capacitance value, voltage rating, and core electrical characteristics while meeting modern availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-F1AE336K is determined by the following mandatory parameters:

• Capacitance value: 33 µF (exact match required)
• Voltage rating: 10 V (minimum, equal or higher acceptable)
• Type: Conformal coated tantalum capacitor
• Mounting: Through hole radial configuration
• Package compatibility: Radial lead spacing and form factor

The identified substitute parts T350F336K010AS (KEMET) and TAP336K010SCS (KYOCERA AVX) satisfy all core substitution criteria. Both maintain the 33 µF capacitance and 10 V voltage specification with conformal coating and radial through-hole mounting. Dimensional variations exist within acceptable mechanical tolerances for board-level integration.

Parameter Comparison

Engineering Selection Recommendations

Both T350F336K010AS and TAP336K010SCS are functionally equivalent substitutes for the obsolete ECS-F1AE336K. Selection between them depends on compliance and availability requirements:

T350F336K010AS (KEMET T350 series) is an active product with extended operating temperature range (-55°C ~ 125°C) and tighter capacitance tolerance (±10%). This part maintains RoHS non-compliance status consistent with the original component.

TAP336K010SCS (KYOCERA AVX TAP series) is an active product with ROHS3 compliance certification, extended operating temperature range (-55°C ~ 125°C), and tighter capacitance tolerance (±10%). This part includes specified lifetime rating (1000 Hrs @ 85°C) and REACH unaffected status. Dimensional footprint is slightly larger (10.00mm height vs. 8.50mm original).

For applications requiring RoHS3 compliance and environmental certifications, TAP336K010SCS is the preferred selection. For applications with existing RoHS non-compliant designs, T350F336K010AS provides direct functional equivalence with active product status and higher inventory availability.

Frequently Asked Questions (FAQ)

Q: Can T350F336K010AS or TAP336K010SCS be used as direct pin-for-pin replacements?

A: Both parts are through-hole radial tantalum capacitors with compatible lead spacing. T350F336K010AS has 0.100" (2.54mm) lead spacing versus the original 0.098" (2.50mm), while TAP336K010SCS maintains 0.098" (2.50mm) spacing. Both are mechanically compatible with standard 0.1" grid PCB layouts. Dimensional height differences (9.90mm and 10.00mm versus 8.50mm original) must be verified for clearance in confined spaces.

Q: What is the significance of the ±10% tolerance in substitute parts versus ±20% in the original?

A: The substitute parts offer tighter capacitance tolerance, which provides improved circuit performance and reduced variation across production batches. This is a beneficial characteristic that does not compromise compatibility.

Q: Are there compliance differences between the two substitute options?

A: Yes. TAP336K010SCS carries ROHS3 compliance and REACH unaffected certification, while T350F336K010AS maintains RoHS non-compliant status matching the original component. Design requirements for environmental compliance should guide selection.

Q: How do the operating temperature ranges compare?

A: The original ECS-F1AE336K operates from -55°C to 105°C. Both substitutes extend the upper limit to 125°C, providing improved thermal margin for high-temperature applications without reducing lower temperature performance.

Q: What is the ESR specification and why does it matter?

A: ESR (Equivalent Series Resistance) is specified as 2.1 Ohm for both substitute parts. The original part does not provide this specification. Lower ESR reduces heat generation and improves high-frequency performance in filtering applications.
