EEE-FP1V221AL Equivalent & Substitute Parts

Part Overview

The EEE-FP1V221AL is a 220 µF, 35 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the FP series. This surface mount device is designed for automotive applications and carries AEC-Q200 qualification. The part is actively produced and available in Tape & Reel packaging with halogen-free construction and ROHS3 compliance.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: capacitance value (220 µF), voltage rating (35 V), tolerance (±20%), operating temperature range (-55°C to 105°C), lifetime specification (2000 Hrs @ 105°C), AEC-Q200 automotive qualification, surface mount package configuration, and physical dimensions (0.315" diameter, 10.50 mm maximum height, 8.30 mm x 8.30 mm land pattern).

Substitute parts are grouped into two categories:

Direct Manufacturer Substitutes: Parts from the same manufacturer (Panasonic) with identical electrical specifications and packaging compatibility, differing only in packaging format (Cut Tape vs. Tape & Reel) or minor height variations within tolerance.

Parametric Equivalents: Parts from alternative manufacturers (Rubycon, KEMET, Chemi-Con) that meet all critical electrical and mechanical parameters. These parts maintain the same capacitance, voltage rating, tolerance, lifetime, temperature range, and physical footprint. Variations in ESR, ripple current, and impedance specifications are noted but do not preclude substitution when the application does not require the specific performance characteristics of the primary part.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 (Unlimited) moisture sensitivity rating. All parts are manufactured to the same physical footprint and surface mount land pattern, ensuring PCB compatibility without layout modifications.

EEE-FP1V221AP is the primary direct substitute, offering identical electrical performance to the main part with the same 80 mOhm ESR specification. The only difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and a minor height reduction of 0.011" (0.30 mm), which remains within standard PCB assembly tolerances.

EEE-FK1V221GL, EEE-FN1V221L, and EEE-FN1V221P are Panasonic parametric equivalents with doubled ESR (160 mOhm) and reduced ripple current handling (600 mA @ 100 kHz versus 850 mA). These parts are suitable for applications where lower ripple current demands do not require the performance characteristics of the primary part.

35TKV220M8X10.5 from Rubycon provides equivalent ESR and ripple current performance to the main part (80 mOhm, 850 mA @ 100 kHz), making it a direct electrical alternative from a different manufacturer.

35TZV220M8X10.5, EEV227M035S9MAA, and EMZA350ARA221MHA0G are parametric equivalents with 160 mOhm ESR and 600 mA ripple current specifications, suitable for applications with lower ripple current requirements.

Frequently Asked Questions (FAQ)

Q: Can EEE-FP1V221AP be used as a direct replacement for EEE-FP1V221AL?

A: Yes. Both parts are from Panasonic's FP series with identical capacitance (220 µF), voltage rating (35 V), tolerance (±20%), ESR (80 mOhm @ 100 kHz), and lifetime (2000 Hrs @ 105°C). The difference is packaging format and a 0.011" height reduction, which does not affect PCB assembly compatibility.

Q: What is the difference between the FP, FK, and FN series from Panasonic?

A: All three series meet the same electrical specifications for this 220 µF, 35 V application. The FK and FN series have higher ESR (160 mOhm) and lower ripple current ratings (600 mA @ 100 kHz) compared to the FP series (80 mOhm, 850 mA @ 100 kHz). Series selection depends on application ripple current requirements.

Q: Are cross-manufacturer substitutes (Rubycon, KEMET, Chemi-Con) fully compatible?

A: Yes, all listed cross-manufacturer parts maintain identical capacitance, voltage rating, tolerance, operating temperature range, lifetime, AEC-Q200 qualification, physical dimensions, and surface mount land pattern. Electrical performance differences (ESR and ripple current) are specified and do not preclude substitution when application requirements are met.

Q: What is the significance of the 80 mOhm versus 160 mOhm ESR difference?

A: ESR affects ripple current handling and thermal performance. The 80 mOhm parts (EEE-FP1V221AL, EEE-FP1V221AP, 35TKV220M8X10.5) support higher ripple current (850 mA @ 100 kHz). The 160 mOhm parts support lower ripple current (600 mA @ 100 kHz). Selection depends on circuit ripple current specifications.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and Cut Tape & Digi-Reel packaging formats do not affect electrical performance. Packaging selection is based on assembly line equipment compatibility and inventory management requirements.

Q: Are all substitute parts halogen-free?

A: The Panasonic FP, FK, and FN series are explicitly halogen-free. Halogen-free status is not specified for Rubycon, KEMET, or Chemi-Con parts in the provided data. Verify halogen-free compliance with the manufacturer if this requirement is mandatory for your application.

Q: Can height variations affect PCB assembly?

A: The height difference between EEE-FP1V221AL (0.413") and EEE-FP1V221AP (0.402") is 0.011" (0.30 mm), which is within standard PCB assembly tolerances and does not require design modifications.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is the automotive electronics council qualification for capacitors used in automotive applications. All listed parts carry this certification, confirming suitability for automotive environments and reliability standards.
