ECS-F1AE107 Equivalent & Substitute Parts

Part Overview

The ECS-F1AE107 is a 100 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. 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECS-F1AE107 is determined by the following critical parameters:

• Capacitance Value: Must be 100 µF
• Voltage Rating: Minimum 10 V (equal or higher ratings are acceptable)
• Tolerance: ±10% or better (tighter tolerance than original ±20%)
• Type: Conformal coated tantalum capacitors
• Mounting: Through hole radial configuration
• Lead Spacing: 0.197" (5.00mm) or compatible spacing
• Operating Temperature: Minimum -55°C ~ 105°C range

Two active substitute parts meet these criteria with enhanced specifications:

1. T350J107K010AS (KEMET) – Matches 10 V rating with improved tolerance and lower ESR
2. TAP107K016CCS (KYOCERA AVX) – Exceeds voltage rating at 16 V with improved tolerance and RoHS3 compliance

Parameter Comparison

Engineering Selection Recommendations

T350J107K010AS (KEMET) provides a direct voltage-rated equivalent with active product status. This part maintains the 10 V rating specification while offering improved tolerance (±10% vs. ±20%) and specified ESR of 1 Ohm. Extended operating temperature range to 125°C provides additional thermal margin. Lead spacing of 0.200" (5.08mm) is nominally compatible with 0.197" (5.00mm) spacing. This part is suitable for applications requiring exact voltage matching and active manufacturer support.

TAP107K016CCS (KYOCERA AVX) offers elevated voltage rating at 16 V, providing design margin for the 10 V application. This part delivers superior ESR performance at 800 mOhm and achieves ROHS3 compliance, addressing environmental and regulatory requirements. Extended operating temperature to 125°C and specified lifetime rating of 1000 Hrs @ 85°C provide documented reliability. Lead spacing matches the original specification at 0.197" (5.00mm). This part is recommended for applications prioritizing compliance, thermal performance, and long-term availability.

Both substitutes are currently in active production with documented inventory availability.

Frequently Asked Questions (FAQ)

Q: Can T350J107K010AS be used as a direct replacement for ECS-F1AE107?

A: Yes. Both parts share 100 µF capacitance, 10 V voltage rating, conformal coated tantalum type, and through-hole radial mounting. The T350J107K010AS offers improved tolerance (±10% vs. ±20%) and specified ESR. Lead spacing differs by 0.003" (0.08mm), which is within typical PCB tolerance for radial component placement.

Q: What is the advantage of TAP107K016CCS over the original ECS-F1AE107?

A: The TAP107K016CCS provides 16 V rating (exceeding the 10 V requirement), lower ESR at 800 mOhm, ROHS3 compliance, and active product status with documented lifetime rating. Lead spacing matches the original specification exactly at 0.197" (5.00mm).

Q: Are there physical size differences between these parts?

A: Yes. The ECS-F1AE107 has a diameter of 0.295" (7.50mm) and height of 0.492" (12.50mm). The T350J107K010AS measures 0.331" Dia (8.40mm) and 0.500" height (12.70mm). The TAP107K016CCS measures 0.354" Dia (9.00mm) and 0.630" height (16.00mm). Physical clearance verification is required for space-constrained applications.

Q: Which substitute is recommended for new designs?

A: Selection depends on application requirements. For voltage-matched operation with active support, use T350J107K010AS. For applications requiring compliance certification, superior ESR performance, and design margin, use TAP107K016CCS.

Q: Are these parts interchangeable on existing PCBs designed for ECS-F1AE107?

A: Electrical interchangeability is confirmed for both substitutes. Physical fit requires verification due to dimensional differences in diameter and height. Lead spacing compatibility is acceptable for both parts.
