• Voltage rating: 16 V (exact match or higher)
• Polarization: Polar (exact match)

Mechanical Equivalence Requirements:

• Mounting type: Through Hole (exact match)
• Package type: Radial, Can (exact match)
• Lead spacing: 0.295" (7.50mm) (exact match)
• Physical dimensions: 0.709" Dia × 1.043" Height (exact match)

Compliance Requirements:

• RoHS3 Compliant status
• REACH Unaffected status

The EKYB160ELL682MM25S from Chemi-Con meets all electrical, mechanical, and compliance criteria for direct substitution with the 688SAK016M.

Parameter Comparison

Engineering Selection Recommendations

The EKYB160ELL682MM25S qualifies as a direct substitute for the 688SAK016M based on matched electrical specifications, identical mechanical form factor, and equivalent regulatory compliance.

Both components are Active products with ROHS3 Compliant and REACH Unaffected status, ensuring compliance with current environmental and safety standards. The substitute part maintains the same capacitance, tolerance, voltage rating, and physical dimensions required for PCB integration and circuit functionality.

The EKYB160ELL682MM25S demonstrates an extended operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C) and increased lifetime rating (10000 Hrs @ 105°C versus 2000 Hrs @ 85°C), providing enhanced thermal performance characteristics within the same package envelope.

Frequently Asked Questions (FAQ)

Q: Can the EKYB160ELL682MM25S replace the 688SAK016M in existing designs?

A: Yes. Both components share identical capacitance (6800 µF), tolerance (±20%), voltage rating (16 V), and physical dimensions (0.709" Dia × 1.043" Height with 0.295" lead spacing). The through-hole radial can package is identical, enabling direct PCB mounting without layout modifications.

Q: Are there differences in electrical performance between these parts?

A: Both parts meet the 6800 µF, 16 V specification. The EKYB160ELL682MM25S provides higher ripple current ratings (3.0005 A @ 120 Hz and 3.53 A @ 100 kHz versus 2.12 A @ 120 Hz and 2.438 A @ 10 kHz for the 688SAK016M) and lower impedance (17 mOhms), indicating improved high-frequency performance characteristics.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 688SAK016M and EKYB160ELL682MM25S are ROHS3 Compliant and REACH Unaffected, meeting current environmental and hazardous substance restrictions.

Q: What is the difference in operating temperature range?

A: The 688SAK016M operates from -40°C to 85°C, while the EKYB160ELL682MM25S operates from -40°C to 105°C. The substitute part supports a wider high-temperature operating window.

Q: Are the lead spacings identical?

A: Yes. Both components have a lead spacing of 0.295" (7.50mm), ensuring compatibility with existing PCB footprints designed for the 688SAK016M.
