Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are qualified equivalents for the EEE-FP1C681AL based on matching electrical specifications, mechanical dimensions, and automotive compliance requirements. Selection among these parts is determined by availability, supply chain requirements, and manufacturing process compatibility.

Panasonic FP Series (EEE-FP1C681AL): Primary part with documented ESR of 60 mOhm @ 100 kHz and ripple current specifications of 833 mA @ 120 Hz and 1.19 A @ 100 kHz. Halogen-free designation confirmed.

Panasonic FK Series (EEE-FK1C681GL and EEE-FK1C681P): Direct Panasonic alternatives with identical electrical and mechanical parameters. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance. The FK series demonstrates lower ripple current ratings (637.5 mA @ 120 Hz and 850 mA @ 100 kHz) with impedance of 80 mOhms. EEE-FK1C681P offers higher inventory availability at 5396 pieces.

Rubycon TZV Series (16TZV680M10X10.5): Cross-manufacturer equivalent with matching core specifications. Carries AEC-Q200 rating and ROHS3 compliance. Ripple current at low frequency is 510 mA @ 120 Hz with 850 mA @ 100 kHz at high frequency. Highest inventory availability at 10200 pieces.

All parts are actively produced and meet automotive application requirements.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1C681GL and EEE-FK1C681P be used interchangeably with EEE-FP1C681AL?

A: Yes. Both Panasonic FK series parts are electrically and mechanically equivalent to the FP series part. They share identical capacitance (680 µF), voltage rating (16 V), tolerance (±20%), operating temperature range (-55°C to 105°C), lifetime (2000 Hrs @ 105°C), physical dimensions (10.00mm diameter × 10.50mm height), and surface mount land size (10.30mm × 10.30mm). All three parts carry AEC-Q200 automotive qualification and ROHS3 compliance.

Q: What are the differences between the Panasonic FP and FK series parts?

A: The primary difference is ESR and ripple current performance. The FP series (EEE-FP1C681AL) specifies 60 mOhm ESR @ 100 kHz with higher ripple current ratings (833 mA @ 120 Hz and 1.19 A @ 100 kHz). The FK series parts specify 80 mOhms impedance with lower ripple current ratings (637.5 mA @ 120 Hz and 850 mA @ 100 kHz). Both series meet the same lifetime and temperature specifications.

Q: Is the Rubycon 16TZV680M10X10.5 a suitable substitute?

A: Yes. The Rubycon TZV series part meets all electrical and mechanical requirements for substitution. It provides 680 µF capacitance at 16 V with ±20% tolerance, -55°C to 105°C operating range, and 2000 Hrs @ 105°C lifetime. Physical dimensions and surface mount land size are identical. AEC-Q200 automotive rating and ROHS3 compliance are confirmed. Ripple current specifications differ slightly (510 mA @ 120 Hz and 850 mA @ 100 kHz).

Q: Are all substitute parts halogen-free?

A: The Panasonic FP and FK series parts are confirmed halogen-free. Halogen-free status is not specified in the provided data for the Rubycon TZV series part.

Q: What is the moisture sensitivity level for these parts?

A: All parts carry Moisture Sensitivity Level 1 (MSL 1), indicating unlimited shelf life without moisture control requirements.

Q: Can these parts be used in non-automotive applications?

A: Yes. While these parts carry AEC-Q200 automotive qualification, they are suitable for any application requiring a 680 µF, 16 V aluminum electrolytic capacitor with the specified electrical and mechanical characteristics.

Q: What is the difference in inventory availability?

A: EEE-FP1C681AL has 1109 pieces in stock. EEE-FK1C681GL has 2733 pieces. EEE-FK1C681P has 5396 pieces. The Rubycon 16TZV680M10X10.5 has the highest availability at 10200 pieces.
