EEF-HD0K680R Equivalent & Substitute Parts

Part Overview

The EEF-HD0K680R is a 68 µF, 8 V aluminum polymer capacitor manufactured by Panasonic Electronic Components in the SP-Cap HD series. This surface mount component is housed in a 2917 (7343 Metric) package with 15 mOhm equivalent series resistance and is rated for general purpose applications across an operating temperature range of -40°C to 125°C. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution of the EEF-HD0K680R is determined by the following critical parameters:

• Capacitance Value: 68 µF (must match exactly)
• Package / Case: 2917 (7343 Metric) (must match for PCB compatibility)
• Mounting Type: Surface Mount (must match for assembly compatibility)
• Voltage Rating: Minimum 8 V (equal or higher voltage rating is acceptable)
• ESR: 15 mOhm (matching specification ensures equivalent electrical performance)
• Tolerance: ±20% (standard tolerance for polymer capacitors)
• Type: Aluminum Polymer (material type must remain consistent)

The KEMET A700D686M010ATE015 qualifies as a direct substitute based on matching capacitance, package, mounting type, ESR, and tolerance specifications. The higher voltage rating (10 V versus 8 V) and extended operating temperature range (-55°C to 125°C) provide enhanced performance margins without compromising circuit compatibility.

Engineering Selection Recommendations

The KEMET A700D686M010ATE015 is the qualified substitute for the obsolete Panasonic EEF-HD0K680R. Selection is supported by the following factors:

• Product Status: The substitute is active and in production, ensuring long-term availability and supply chain continuity.
• Electrical Equivalence: Matching capacitance, tolerance, ESR, and package specifications guarantee direct functional replacement without circuit redesign.
• Enhanced Performance Margins: The 10 V voltage rating provides 25% additional voltage headroom compared to the original 8 V specification, improving reliability in applications with voltage transients.
• Compliance: The KEMET part is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.
• Packaging: Available in Tape & Reel format for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the A700D686M010ATE015 be used as a direct replacement for the EEF-HD0K680R?

A: Yes. Both components share identical capacitance (68 µF), tolerance (±20%), ESR (15 mOhm), and package specifications (2917 / 7343 Metric). The higher voltage rating of the substitute does not affect compatibility in circuits designed for 8 V operation.

Q: What is the significance of the higher voltage rating on the KEMET part?

A: A 10 V rated capacitor can safely operate at voltages up to 10 V. In an 8 V circuit, this provides additional safety margin and typically results in improved capacitor lifespan and reduced failure rates under transient voltage conditions.

Q: Are the physical dimensions identical between the two parts?

A: Both components use the 2917 (7343 Metric) package. The length and width are identical at 0.287" × 0.169" (7.30 mm × 4.30 mm). The seated height differs slightly: 0.118" (3.00 mm) for the Panasonic versus 0.122" (3.10 mm) for the KEMET. This 0.04 mm difference is within standard PCB assembly tolerances and does not affect mounting compatibility.

Q: What does the higher ripple current rating on the KEMET part indicate?

A: The KEMET A700D686M010ATE015 is rated for 4.1 A ripple current at 100 kHz, compared to 2.5 A for the original part. This indicates the substitute can handle higher AC current stress without exceeding temperature limits, providing additional performance headroom in high-frequency switching applications.

Q: Are there any moisture sensitivity considerations?

A: Both components carry MSL (Moisture Sensitivity Level) 3 rating with a 168-hour floor life. Standard moisture control procedures during storage and assembly apply equally to both parts.
