Engineering Selection Recommendations

Direct Manufacturer Equivalent (Chemi-Con):

EMZA160ARA681MJA0G is the direct active equivalent from Chemi-Con. This part maintains identical electrical specifications to the MZA16VC681MJ10TP while offering ROHS3 compliance and AEC-Q200 automotive certification. The height increases from 0.394" to 0.413", which remains within acceptable PCB layout tolerances for radial can SMD packages. This part is suitable for direct replacement in applications where the original obsolete part is no longer available.

Upgraded Substitutes with Enhanced Performance:

EMZJ160ARA681MJA0G (Chemi-Con) and 16TKV680M10X10.5 (Rubycon) offer reduced ESR of 60 mOhms at 100 kHz and increased ripple current capability of 1.19 A at 100 kHz, compared to the original 80 mOhms and 850 mA. These upgrades are beneficial for applications requiring lower impedance or higher ripple current handling. Both parts carry AEC-Q200 certification and ROHS3 compliance.

16TLV680M10X10.5 (Rubycon) extends the lifetime rating to 5000 hours at 105°C, providing enhanced reliability for long-term applications. This part maintains the original 80 mOhms impedance and 850 mA ripple current while offering AEC-Q200 certification and ROHS3 compliance.

16TZV680M10X10.5 (Rubycon) provides a high-inventory alternative with identical electrical specifications to the original part, including 80 mOhms impedance and 850 mA ripple current at 100 kHz. This part carries AEC-Q200 certification and ROHS3 compliance.

Parametric Equivalents:

EMVY160ARA681MJA0G (Chemi-Con) maintains the original 0.394" height and is suitable for space-constrained applications. However, the impedance increases to 150 mOhms and ripple current decreases to 670 mA at 100 kHz. This part is appropriate for general-purpose applications where the reduced performance characteristics are acceptable.

AFK687M16G24T-F (Cornell Dubilier Electronics) and EEE-FK1C681P (Panasonic Electronic Components) are cross-manufacturer alternatives with identical electrical specifications to the original part. Both carry AEC-Q200 certification and ROHS3 compliance. The AFK part features a wider surface mount land size of 0.473" W, which may require PCB layout adjustment.

Voltage-Rated Upgrade:

EEE-FK1E681SP (Panasonic Electronic Components) is rated at 25 V instead of 16 V, providing overvoltage margin for applications subject to transient voltage spikes. This part is classified as "Not For New Designs" and should be used only when the higher voltage rating is specifically required. The 25 V rating does not affect compatibility with 16 V nominal circuits.

Compliance and Regulatory Status:

All substitute parts listed are ROHS3 compliant and REACH unaffected, addressing regulatory requirements that the original obsolete part does not meet. Parts carrying AEC-Q200 certification are qualified for automotive applications and meet stringent reliability standards. Selection should prioritize active product status parts for long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can EMZA160ARA681MJA0G be used as a direct replacement for MZA16VC681MJ10TP?

A: Yes. EMZA160ARA681MJA0G is the direct active equivalent from Chemi-Con. It maintains identical capacitance (680 µF), voltage rating (16 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), operating temperature range (-55°C to 105°C), and impedance (80 mOhms). The height increases from 0.394" to 0.413", which is within acceptable tolerances for radial can SMD packages. ROHS3 compliance and AEC-Q200 certification are additional benefits.

Q: What is the difference between the upgraded substitutes EMZJ160ARA681MJA0G and 16TKV680M10X10.5?

A: Both parts offer identical performance upgrades: ESR reduced to 60 mOhms at 100 kHz and ripple current increased to 1.19 A at 100 kHz. The primary difference is manufacturer—EMZJ160ARA681MJA0G is from Chemi-Con, while 16TKV680M10X10.5 is from Rubycon. Both carry AEC-Q200 certification and ROHS3 compliance. Selection depends on supply chain preference and inventory availability.

Q: Why does 16TLV680M10X10.5 have a higher lifetime rating of 5000 hours?

A: The 16TLV680M10X10.5 is engineered with enhanced internal construction to extend operational life at elevated temperatures. This part maintains the original 80 mOhms impedance and 850 mA ripple current while providing extended reliability. The 5000-hour rating is beneficial for applications requiring long-term operation without maintenance or replacement.

Q: Can EEE-FK1E681SP (25 V) be used in place of the 16 V rated original part?

A: Yes. EEE-FK1E681SP is rated at 25 V and is electrically compatible with 16 V nominal circuits. The higher voltage rating provides additional safety margin against transient overvoltages. However, this part is classified as "Not For New Designs" and should be used only when the higher voltage rating is specifically required or when 16 V alternatives are unavailable. The 25 V rating does not degrade performance in 16 V applications.

Q: What is the significance of AEC-Q200 certification on substitute parts?

A: AEC-Q200 certification indicates that the part meets automotive-grade reliability standards established by the Automotive Electronics Council. These parts undergo rigorous qualification testing for temperature cycling, vibration, humidity, and other environmental stresses. AEC-Q200 certification is required for automotive applications and provides assurance of long-term reliability in demanding environments.

Q: Does the increased height of 0.413" on some substitutes affect PCB layout?

A: The height increase from 0.394" to 0.413" is minimal (0.019" or 0.5mm) and typically does not require PCB layout modification. Standard PCB design practices accommodate this variation within component height tolerances. However, applications with extremely tight vertical clearance constraints should verify compatibility with specific board designs.

Q: Why does EMVY160ARA681MJA0G have higher impedance (150 mOhms) than the original part?

A: EMVY160ARA681MJA0G is designed for general-purpose applications where lower impedance is not critical. The higher impedance results from different internal construction optimized for cost and general-purpose performance. This part is suitable for applications where impedance performance is not a limiting factor, such as bulk energy storage or filtering applications with lower frequency ripple current requirements.

Q: What is the difference in surface mount land size between AFK687M16G24T-F and other substitutes?

A: AFK687M16G24T-F features a surface mount land size of 0.406" L x 0.473" W, compared to the standard 0.406" L x 0.406" W on most other substitutes. The wider land size (0.473" W versus 0.406" W) may require PCB layout adjustment to accommodate the larger footprint. Verify PCB design compatibility before selecting this part.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All substitute parts listed are available in Tape & Reel packaging, which is standard for surface mount production environments. The original MZA16VC681MJ10TP does not specify packaging format in the provided data, but all active substitutes support automated assembly processes through TR packaging.

Q: Which substitute offers the best overall performance upgrade?

A: 16TLV680M10X10.5 (Rubycon) provides the most comprehensive upgrade, combining extended lifetime (5000 Hrs @ 105°C), maintained impedance (80 mOhms), AEC-Q200 certification, and ROHS3 compliance. For applications requiring lower impedance and higher ripple current, EMZJ160ARA681MJA0G (Chemi-Con) or 16TKV680M10X10.5 (Rubycon) are optimal choices with 60 mOhms ESR and 1.19 A ripple current capability.
