ECS-F1CE155K Equivalent & Substitute Parts

Part Overview

The ECS-F1CE155K is a 1.5 µF conformal coated tantalum capacitor rated at 16 V with radial through-hole mounting. Manufactured by Panasonic Electronic Components as part of the EF series, this component is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, identifying equivalent substitute parts is essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution for the ECS-F1CE155K is determined by the following critical parameters:

• Capacitance Value: 1.5 µF (exact match required)
• Voltage Rating: 16 V (minimum requirement; higher ratings acceptable)
• Type: Conformal Coated Tantalum (functional requirement)
• Mounting Type: Through Hole Radial (physical requirement)
• Operating Temperature Range: Must support -55°C minimum and 105°C maximum

The substitute parts listed below meet all mandatory electrical and mechanical parameters. Tolerance variations (±20% vs. ±10%) and ESR differences are acceptable within the scope of equivalent substitution for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

T350A155K016AS (KEMET): This substitute maintains active product status and meets all electrical specifications. The ±10% tolerance provides improved capacitance accuracy compared to the original ±20%. Operating temperature range extends to 125°C, exceeding the original specification. RoHS non-compliance status matches the original part. This option is suitable for applications where legacy compliance requirements are maintained.

TAP155K016SCS (KYOCERA AVX): This substitute is the preferred option for new designs and production continuity. It maintains active product status with the highest inventory availability (4221 Pcs). The TAP series offers ROHS3 compliance, addressing modern regulatory requirements. Operating temperature range extends to 125°C. The ±10% tolerance and 10 Ohm ESR specification provide superior performance characteristics. Lifetime rating of 1000 Hrs @ 85°C is documented.

Frequently Asked Questions (FAQ)

Q: Can T350A155K016AS and TAP155K016SCS be used interchangeably with ECS-F1CE155K?

A: Both parts are electrically equivalent for the specified 1.5 µF, 16 V application. All three components are conformal coated tantalum capacitors with radial through-hole mounting. The substitute parts exceed the original operating temperature range and provide equal or superior tolerance specifications.

Q: What are the physical dimension differences?

A: The ECS-F1CE155K has a diameter of 0.130" (3.30mm) and height of 0.217" (5.50mm). Both substitute parts have larger dimensions: 0.177" diameter (4.50mm) and heights of 0.280" (7.10mm) for KEMET and 0.276" (7.00mm) for KYOCERA AVX. PCB layout verification is required before substitution.

Q: Which substitute part should be selected for new production?

A: TAP155K016SCS is recommended for new production due to active status, ROHS3 compliance, highest inventory availability, and documented lifetime rating. T350A155K016AS is an acceptable alternative where legacy compliance requirements are specified.

Q: Are there any lead spacing considerations?

A: The ECS-F1CE155K has 0.098" (2.50mm) lead spacing. T350A155K016AS has 0.100" (2.54mm) spacing, and TAP155K016SCS has 0.098" (2.50mm) spacing. Lead spacing differences may require PCB footprint adjustment.

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

A: The substitute parts provide tighter capacitance tolerance, resulting in more predictable circuit performance. This is a functional improvement over the original specification and does not create compatibility issues.
