Substitute Part Grouping Explanation

Substitution of the EEE-FC0J680P is determined by the following critical parameters:

Mandatory Matching Parameters:

Capacitance: 68 µF (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - SMD (exact match required)
Mounting Type: Surface Mount (exact match required)
Physical Dimensions: 0.248" Dia (6.30mm), Height ≤ 0.228" (5.80mm), Land Size 0.260" L x 0.260" W (exact match required)
Polarization: Polar (exact match required)
MSL Rating: 1 (Unlimited) (exact match required)

Flexible Parameters (May Vary):

Voltage Rating: 6.3 V or higher (higher voltage ratings are acceptable for direct substitution)
Lifetime @ Temp.: 1000 Hrs @ 105°C or longer (extended lifetime is acceptable)
Operating Temperature Range: -40°C to 105°C or wider (extended range is acceptable)
Product Status: Active preferred over "Not For New Designs"
Manufacturer: Different manufacturers acceptable if all other parameters match

Substitute parts are categorized as "Upgrade" when they offer improved specifications (higher voltage rating, extended lifetime, or active product status) while maintaining identical physical and electrical core parameters. Parts are categorized as "Similar" when voltage rating differs but all other critical parameters remain compatible.

Engineering Selection Recommendations

Direct Equivalents (Same Voltage Rating - 6.3 V):

AFC686M06D16T-F (Cornell Dubilier Electronics) and UWG0J680MCL1GB (Nichicon) are direct functional equivalents to the EEE-FC0J680P. Both maintain identical capacitance, voltage rating, tolerance, physical dimensions, and package specifications. Both are classified as Active products with ROHS3 compliance, providing improved product lifecycle status compared to the original part. Both support the same automotive and general-purpose applications with AEC-Q200 ratings.

Upgrade Options (Higher Voltage Rating):

EEE-FP1C680AP (16 V), EEE-HB1A680AP (10 V), and EEE-FP1E680AP (25 V) from Panasonic, along with EEV686M025S9GAA (25 V) from KEMET, are upgrade substitutes. These parts maintain the 68 µF capacitance, ±20% tolerance, and identical land size footprint. Higher voltage ratings provide increased design margin and reliability in applications where the original 6.3 V specification may be marginal. All upgrade options are Active products with extended 2000-hour lifetimes at 105°C, compared to the original 1000-hour rating. Physical height variations (0.228" maximum for Panasonic FP and HB series, 0.222" for KEMET EEV series) remain within acceptable PCB assembly tolerances.

Selection Criteria:

For direct replacement in existing designs, select AFC686M06D16T-F or UWG0J680MCL1GB to maintain identical electrical and physical specifications while benefiting from active product status. For new designs or design revisions, Panasonic FP or HB series upgrades are preferred due to extended lifetime ratings and active product status. KEMET EEV686M025S9GAA is suitable where higher voltage margin and extended lifetime are required, with the understanding that ESR characteristics differ (520 mOhm @ 100 kHz versus unspecified for the original part).

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute for the EEE-FC0J680P?

A: Yes. Higher voltage ratings (10 V, 16 V, or 25 V) are acceptable substitutes provided all other parameters match: capacitance (68 µF), tolerance (±20%), package type (Radial, Can - SMD), physical dimensions, and land size. Higher voltage ratings provide increased design margin without affecting circuit functionality.

Q: What is the difference between "Upgrade" and "Similar" substitute classifications?

A: "Upgrade" substitutes offer improved specifications (higher voltage rating, extended lifetime, or active product status) while maintaining identical physical and core electrical parameters. "Similar" substitutes have different voltage ratings but are otherwise compatible. Both categories maintain the same capacitance, tolerance, package type, and footprint.

Q: Are there physical height differences between substitute parts?

A: Yes. The original EEE-FC0J680P has a maximum seated height of 0.213" (5.40mm). Panasonic FP and HB series upgrades have a maximum height of 0.228" (5.80mm), and KEMET EEV686M025S9GAA has a maximum height of 0.222" (5.65mm). These variations remain within standard PCB assembly tolerances and do not affect functionality. Verify clearance in your specific PCB layout before implementation.

Q: Is the EEE-FC0J680P still available for new designs?

A: No. The EEE-FC0J680P is classified as "Not For New Designs." For new designs, select from Active product alternatives such as EEE-FP1C680AP, EEE-HB1A680AP, AFC686M06D16T-F, or UWG0J680MCL1GB.

Q: Do all substitute parts have the same ripple current ratings?

A: No. Ripple current specifications vary by manufacturer and series. The original EEE-FC0J680P specifies 105 mA @ 120 Hz and 140 mA @ 100 kHz. Panasonic FP series upgrades specify 195 mA @ 120 Hz and 300 mA @ 100 kHz. Verify ripple current requirements for your specific application before selecting a substitute.

Q: What is the significance of AEC-Q200 rating on these parts?

A: AEC-Q200 is an automotive qualification standard. All listed substitute parts carry AEC-Q200 certification, confirming suitability for automotive applications with defined reliability and performance standards.

Q: Can I mix different manufacturers' parts in the same design?

A: Yes. All listed substitutes maintain identical capacitance, tolerance, package type, and land size specifications. Different manufacturers (Panasonic, Cornell Dubilier, Nichicon, KEMET) are interchangeable provided the specific part number specifications match your circuit requirements.
