Substitute Part Grouping Explanation

Substitute parts for the EEE-FTJ681XAP are qualified based on the following criteria:

• Capacitance value: 680 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100 kHz: 160 mOhm (exact match required)
• Lifetime @ 105°C: 2000 Hrs (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Ripple current @ 100 kHz: 600 mA minimum (equal or greater acceptable)
• Package type: Radial, Can - SMD (exact match required)
• Case dimensions: 0.248" Dia (6.30 mm) × 0.315" H (8.00 mm) (exact match required)
• Land size: 0.260" L × 0.260" W (6.60 mm × 6.60 mm) (exact match required)
• Mounting type: Surface Mount (exact match required)
• AEC-Q200 rating: Required for automotive applications
• RoHS compliance: ROHS3 Compliant (exact match required)
• MSL rating: 1 (Unlimited) (exact match required)

Two substitute parts meet these criteria: EEE-FTJ681XAL (Panasonic) and EMZR6R3ARA681MF80G (Chemi-Con).

Parameter Comparison

Engineering Selection Recommendations

All three parts—EEE-FTJ681XAP, EEE-FTJ681XAL, and EMZR6R3ARA681MF80G—are Active status components with identical electrical specifications and AEC-Q200 automotive qualification. Selection between these parts is determined by packaging availability and supply chain requirements.

EEE-FTJ681XAP and EEE-FTJ681XAL are both Panasonic products within the FT series. The primary difference is packaging format: EEE-FTJ681XAP is supplied in Cut Tape (CT) & Digi-Reel® format, while EEE-FTJ681XAL is supplied in Tape & Reel (TR) format. Both maintain identical electrical performance and compliance certifications.

EMZR6R3ARA681MF80G is a Chemi-Con Alchip™-MZR series equivalent. This part meets all core electrical and mechanical requirements with one minor variance: ripple current at 120 Hz is 360 mA compared to 420 mA in the Panasonic variants. At 100 kHz, all three parts deliver 600 mA ripple current capacity. The Chemi-Con part is supplied in Tape & Reel (TR) format.

All three parts are ROHS3 compliant with MSL rating 1 (Unlimited) and are suitable for direct substitution in automotive applications requiring AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can EEE-FTJ681XAL be used as a direct replacement for EEE-FTJ681XAP?

A: Yes. Both parts are Panasonic FT series capacitors with identical electrical specifications, case dimensions, land size, and compliance ratings. The difference is packaging format: EEE-FTJ681XAP uses Cut Tape (CT) & Digi-Reel® while EEE-FTJ681XAL uses Tape & Reel (TR). Selection depends on assembly equipment compatibility and supply chain requirements.

Q: Is EMZR6R3ARA681MF80G compatible with designs specified for EEE-FTJ681XAP?

A: Yes. The Chemi-Con EMZR6R3ARA681MF80G meets all critical electrical parameters: 680 µF capacitance, 6.3 V rating, 160 mOhm ESR @ 100 kHz, 2000-hour lifetime @ 105°C, and 600 mA ripple current @ 100 kHz. Case dimensions and land size are identical. The part carries AEC-Q200 rating and ROHS3 compliance. The ripple current at 120 Hz is 360 mA versus 420 mA in Panasonic variants; this difference does not affect substitution eligibility for the specified electrical parameters.

Q: What is the significance of the packaging difference between Cut Tape and Tape & Reel formats?

A: Packaging format affects assembly process compatibility. Cut Tape (CT) & Digi-Reel® format is suitable for manual or semi-automated assembly. Tape & Reel (TR) format is optimized for high-speed automated pick-and-place assembly equipment. Electrical performance and component specifications remain identical regardless of packaging format.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 qualification, which certifies suitability for automotive applications. Operating temperature range (-55°C ~ 105°C), lifetime rating (2000 Hrs @ 105°C), and compliance certifications meet automotive industry standards.

Q: What does MSL rating 1 (Unlimited) mean for component handling?

A: MSL (Moisture Sensitivity Level) rating 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This simplifies logistics and reduces component damage risk from moisture absorption.
