Engineering Selection Recommendations

Direct Equivalents (Same Voltage Rating - 16 V):

EEE-TC1C101P (Panasonic) and 16THV100M8X10.5 (Rubycon) are direct substitutes with identical electrical specifications. Both are Active products with AEC-Q200 certification, making them suitable for automotive and high-reliability applications. EEE-TC1C101P offers superior ripple current handling (410 mA @ 100 kHz vs. 300 mA), while 16THV100M8X10.5 provides AEC-Q200 automotive qualification. Both accommodate the same PCB land pattern with minor height variations (0.413" vs. 0.394").

Voltage Upgrade Options:

UCZ1E101MCL1GS (25 V) and UCZ1V101MCL1GS (35 V) from Nichicon maintain identical ESR and lifetime specifications while providing higher voltage margins. These are suitable when circuit design permits voltage derating. Both remain Not For New Designs status.

For active product status with voltage upgrades, select 25THV100M8X10.5 (Rubycon, 25 V) or 35THV100M8X10.5 (Rubycon, 35 V). Both carry AEC-Q200 certification and Active product status. The 35 V options provide maximum design margin and are available in high inventory quantities.

EEE-TC1E101P (Panasonic, 25 V) offers Active status with AEC-Q200 certification and superior ripple current performance (410 mA @ 100 kHz).

Similar Alternatives (Same Voltage - 16 V, Different Characteristics):

UCJ1C101MCL1GS (Nichicon, Active status) is electrically similar but exhibits higher ESR (2 Ohm vs. 200 mOhm) and shorter lifetime (2000 Hrs vs. 3000 Hrs). This part is suitable only when ESR and lifetime constraints are relaxed.

UCZ1C101MCL6GS (Nichicon, Not For New Designs) is a smaller footprint variant (0.248" Dia, 6.30 mm) with higher ESR (450 mOhm) and reduced ripple current capacity. This part is not recommended for new applications due to both product status and performance degradation.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity. Rubycon and Panasonic parts carry AEC-Q200 automotive qualification, providing additional reliability assurance for mission-critical applications.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage rated capacitor as a substitute?

A: Yes. A 25 V or 35 V rated capacitor is a valid substitute for a 16 V application, provided all other parameters (capacitance, tolerance, package, land size) match exactly. Higher voltage ratings provide additional design margin and are electrically compatible with lower voltage circuits.

Q: What is the difference between ESR values, and does it matter?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat dissipation. Lower ESR values (200 mOhm) are superior to higher values (300 mOhm or 450 mOhm). If your circuit requires specific ripple current performance, verify the substitute part's ESR and ripple current ratings match or exceed the original specification.

Q: Why do some parts have different heights?

A: Physical height variations (0.394" to 0.413") result from different manufacturing series and internal construction. Verify PCB clearance and component placement constraints before substituting. Height differences of 0.019" (0.5 mm) may affect board assembly in space-constrained designs.

Q: What does "Not For New Designs" mean?

A: This product status indicates the part has reached end-of-life and is no longer recommended for new circuit designs. Existing inventory may remain available, but long-term supply is not guaranteed. For new designs, select Active status parts such as EEE-TC1C101P, 16THV100M8X10.5, or Rubycon THV/TGV series.

Q: Are Rubycon and Panasonic parts compatible with Nichicon footprints?

A: Yes, provided the surface mount land size (0.327" L x 0.327" W / 8.30 mm x 8.30 mm) matches exactly. All listed substitutes share this land pattern. Physical height and diameter may vary slightly, but PCB pad compatibility is maintained.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive electronics qualification standard. Parts carrying this certification have undergone rigorous reliability testing and are approved for automotive applications. Rubycon THV/TGV series and Panasonic TC series all carry AEC-Q200 certification.

Q: Can I substitute a part with lower ripple current rating?

A: No. If your circuit requires 270 mA ripple current @ 100 kHz, you must select a substitute with equal or higher ripple current capacity. Undersized ripple current ratings result in excessive heat generation and premature capacitor failure.

Q: What is the difference between 35TGV100M8X10.5 and 35THV100M8X10.5?

A: Both are 35 V, 100 µF Rubycon capacitors with identical footprints and Active status. The primary difference is ESR: 35TGV100M8X10.5 has 150 mOhm (superior performance), while 35THV100M8X10.5 has 300 mOhm. Select 35TGV100M8X10.5 for applications requiring lower ESR and better ripple current handling.
