EEE-FT1E101AV Equivalent & Substitute Parts

Part Overview

The EEE-FT1E101AV is a 100 µF, 25 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Panasonic Electronic Components. This component is rated for automotive applications and high temperature reflow processes, with AEC-Q200 qualification and ROHS3 compliance. The part is currently in active production status with 1228 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design revisions require alternative qualified sources. The EEE-FK1E101SV serves as a parametric equivalent for applications where the primary part is unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-FT1E101AV is determined by strict equivalence across the following parameters:

Capacitance value must be 100 µF. Voltage rating must be 25 V. Tolerance must be ±20%. Package type must be Radial, Can - SMD with identical physical dimensions (0.248" Dia, 0.252" Height) and land size (0.260" L x 0.260" W). Operating temperature range must span -55°C ~ 105°C. Lifetime rating must be 2000 Hrs @ 105°C. Polarization must be polar. Compliance certifications must include AEC-Q200, ROHS3, and REACH Unaffected status.

The EEE-FK1E101SV meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The EEE-FT1E101AV is the preferred selection for new designs due to its active production status. This part maintains full manufacturing support and is recommended for all new applications requiring a 100 µF, 25 V aluminum electrolytic capacitor with automotive-grade qualification.

The EEE-FK1E101SV is classified as "Not For New Designs" and serves as a substitute only when the primary part is unavailable. While this substitute maintains electrical equivalence in capacitance, voltage rating, tolerance, and compliance certifications, it exhibits higher ESR (360 mOhm versus 260 mOhm) and lower ripple current ratings. Both parts are manufactured by Panasonic Electronic Components and share identical physical dimensions and land sizes, ensuring PCB compatibility.

Selection between these parts should be based on availability and design phase. Active production designs must use EEE-FT1E101AV. Legacy or maintenance designs may use EEE-FK1E101SV when the primary part is unavailable, provided the higher ESR and lower ripple current specifications do not exceed circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1E101SV be used as a direct replacement for EEE-FT1E101AV?

A: Yes, from a physical and electrical standpoint. Both parts share identical capacitance (100 µF), voltage rating (25 V), tolerance (±20%), package dimensions, and land sizes. However, the substitute exhibits higher ESR and lower ripple current ratings. Circuit analysis must confirm these differences do not impact performance.

Q: What is the primary difference between these two parts?

A: The main differences are ESR and ripple current specifications. EEE-FT1E101AV has 260 mOhm ESR and 300 mA ripple current at 100 kHz. EEE-FK1E101SV has 360 mOhm ESR and 240 mA ripple current at 100 kHz. Both maintain identical lifetime ratings and temperature ranges.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 qualification and are rated for automotive and high temperature reflow applications. Both operate across -55°C ~ 105°C and maintain 2000 hour lifetime at 105°C.

Q: Will these parts fit the same PCB footprint?

A: Yes. Both parts have identical physical dimensions (0.248" diameter, 0.252" height) and surface mount land sizes (0.260" L x 0.260" W). No PCB redesign is required for substitution.

Q: Why is EEE-FK1E101SV marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. Panasonic recommends using EEE-FT1E101AV for new designs to ensure long-term availability and manufacturing support.

Q: Are both parts ROHS3 compliant?

A: Yes. Both EEE-FT1E101AV and EEE-FK1E101SV are ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH Unaffected status.
