Engineering Selection Recommendations

All identified substitute parts maintain active product status and full compliance with AEC-Q200 automotive qualification and ROHS3 environmental standards. Selection between the main part and substitutes is based on the following considerations:

Panasonic FP Series (EEE-FP1C680AL and EEE-FP1C680AP): These parts are direct manufacturer equivalents within the same FP series. The EEE-FP1C680AP differs only in seated height (5.80 mm versus 6.10 mm), which may be advantageous in space-constrained designs. Both maintain identical electrical specifications including 260 mOhm ESR and 300 mA ripple current at 100 kHz.

Panasonic FK Series (EEE-FK1C680P): This part represents a parametric equivalent from Panasonic's FK series. It maintains all critical electrical and mechanical parameters but exhibits slightly reduced ripple current capability (240 mA at 100 kHz versus 300 mA). This part carries the highest inventory availability at 9107 units.

Nichicon UCD Series (UCD1C680MCL1GS): This part is a cross-manufacturer substitute from Nichicon. It meets all primary electrical and mechanical requirements. The REACH status differs from Panasonic parts (REACH Affected versus REACH Unaffected). Ripple current specification is 240 mA at 100 kHz.

Nichicon UUD Series (UUD1C680MCL1GS): This part is a cross-manufacturer substitute from Nichicon's UUD series. It maintains compliance with all critical parameters. The impedance specification is 440 mOhms, and ripple current is 230 mA at 100 kHz. REACH status is Affected.

Frequently Asked Questions (FAQ)

Q: Can EEE-FP1C680AP be used as a direct replacement for EEE-FP1C680AL?

A: Yes. Both parts are Panasonic FP series devices with identical electrical specifications (68 µF, 16 V, ±20%, 260 mOhm ESR, 300 mA ripple current at 100 kHz). The only difference is seated height: EEE-FP1C680AP is 5.80 mm versus 6.10 mm for EEE-FP1C680AL. Verify PCB clearance requirements before substitution.

Q: What is the difference between Panasonic and Nichicon substitutes?

A: All parts meet identical electrical and mechanical specifications for capacitance, voltage, tolerance, temperature range, and lifetime. Differences exist in ripple current ratings and impedance values. Panasonic FP series offers 300 mA ripple current at 100 kHz, while Nichicon UCD and UUD series offer 240 mA and 230 mA respectively. REACH compliance status also differs between manufacturers.

Q: Are the Nichicon UCD1C680MCL1GS and UUD1C680MCL1GS interchangeable?

A: Both Nichicon parts meet the core electrical and mechanical requirements. UCD1C680MCL1GS provides 240 mA ripple current at 100 kHz with 360 mOhms impedance. UUD1C680MCL1GS provides 230 mA ripple current at 100 kHz with 440 mOhms impedance. Selection depends on ripple current and impedance requirements for the specific application.

Q: Do all substitute parts carry AEC-Q200 automotive qualification?

A: Yes. All identified substitute parts (EEE-FP1C680AP, EEE-FK1C680P, UCD1C680MCL1GS, and UUD1C680MCL1GS) carry AEC-Q200 qualification and are suitable for automotive applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts are ROHS3 compliant. However, REACH status varies: Panasonic parts are REACH Unaffected, while Nichicon parts are REACH Affected. Verify REACH compliance requirements for your specific application and region.

Q: What is the impact of different ripple current ratings on part selection?

A: Ripple current rating determines the maximum AC current the capacitor can handle at specified frequency without exceeding temperature limits. EEE-FP1C680AL and EEE-FP1C680AP support 300 mA at 100 kHz. EEE-FK1C680P supports 240 mA, and Nichicon parts support 240 mA (UCD) or 230 mA (UUD). Select based on your circuit's actual ripple current requirements.

Q: Can the EEE-FK1C680P be used in place of EEE-FP1C680AL?

A: Yes, from an electrical and mechanical standpoint. Both maintain 68 µF, 16 V, ±20% tolerance, 2000 Hrs @ 105°C lifetime, and identical case dimensions. The FK series exhibits lower ripple current (240 mA versus 300 mA at 100 kHz). Verify that your application's ripple current requirement does not exceed 240 mA at 100 kHz.

Q: What inventory considerations should guide part selection?

A: EEE-FK1C680P offers the highest inventory availability at 9107 units. EEE-FP1C680AP provides 4561 units. UCD1C680MCL1GS provides 3115 units. EEE-FP1C680AL and UUD1C680MCL1GS offer lower availability at 1092 and 1956 units respectively. Supply chain continuity may favor higher-inventory alternatives.
