Engineering Selection Recommendations

The A700D686M010ATE015 is a direct functional substitute for the ESRH680M08R based on the following engineering criteria:

Compliance and Certification: Both parts maintain ROHS3 compliance and identical MSL ratings (3, 168 Hours), ensuring compatibility with current manufacturing and environmental standards.

Product Status: The ESRH680M08R is obsolete, while the A700D686M010ATE015 maintains active production status with KEMET. This ensures long-term availability and supply chain continuity.

Electrical Performance: The substitute part matches all critical electrical parameters (capacitance, tolerance, ESR, and package) while providing enhanced performance margins in voltage rating (10 V vs. 8 V), operating temperature range (-55°C to 125°C vs. -55°C to 105°C), lifetime rating (2000 Hrs @ 125°C vs. 1000 Hrs @ 105°C), and ripple current capacity (4.1 A vs. 2.5 A at 100 kHz).

Physical Compatibility: Both parts utilize identical 2917 (7343 Metric) surface mount packages with matching land sizes (0.287" L x 0.169" W / 7.30 mm x 4.30 mm), ensuring PCB layout compatibility without redesign.

Packaging Consideration: The substitute is supplied in Tape & Reel format, which is standard for automated assembly operations. Bulk packaging availability should be confirmed with the supplier if required for specific production workflows.

Frequently Asked Questions (FAQ)

Q: Can the A700D686M010ATE015 be used as a direct replacement for the ESRH680M08R on existing PCBs?

A: Yes. Both parts share identical package dimensions (2917 / 7343 Metric), land sizes, and mounting type (surface mount). No PCB layout modifications are required. The substitute's higher voltage rating (10 V) and enhanced thermal performance provide additional design margin.

Q: What is the significance of the voltage rating difference (8 V vs. 10 V)?

A: The substitute part's 10 V rating exceeds the original 8 V specification. In circuit applications, the substitute will operate at lower stress levels when exposed to the same voltage conditions, extending component life and improving reliability margins.

Q: Are there any thermal performance differences between these parts?

A: The A700D686M010ATE015 offers superior thermal performance with an operating temperature range of -55°C to 125°C (versus -55°C to 105°C) and a lifetime rating of 2000 hours at 125°C (versus 1000 hours at 105°C). This makes the substitute suitable for applications with higher ambient temperature requirements.

Q: Does the ripple current rating difference affect circuit design?

A: The substitute's ripple current rating of 4.1 A at 100 kHz exceeds the original 2.5 A specification. This provides additional margin for high-frequency switching applications and reduces thermal stress on the component during operation.

Q: What is the impact of the different packaging formats (bulk vs. Tape & Reel)?

A: The ESRH680M08R is supplied in bulk packaging, while the A700D686M010ATE015 is supplied in Tape & Reel format. Tape & Reel is standard for automated pick-and-place assembly. If bulk quantities are required, packaging format availability should be confirmed with the supplier.

Q: Are both parts RoHS compliant?

A: Yes. Both the ESRH680M08R and A700D686M010ATE015 are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and assembly.

Q: What does the MSL rating of 3 (168 Hours) mean for handling and storage?

A: MSL 3 indicates Moisture Sensitivity Level 3, requiring storage in controlled humidity conditions (not exceeding 60% relative humidity at 25°C) for a maximum of 168 hours after packaging opening. Both parts share this specification, ensuring identical handling and storage protocols.

Q: Is the ±20% tolerance specification identical between both parts?

A: Yes. Both parts maintain ±20% capacitance tolerance, ensuring equivalent performance characteristics in circuit applications where tolerance specifications are critical.
