Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Direct Electrical Equivalents maintain identical or superior electrical performance within the same voltage class (16 V). These parts share the same capacitance (100 µF), tolerance (±20%), lifetime rating (2000 Hrs @ 125°C), and operating temperature range (-40°C to 125°C).

Upgrade Substitutes provide higher voltage ratings (25 V or 35 V) while maintaining the same capacitance and tolerance. These are backward-compatible for 16 V applications and offer improved design margin.

Parametric Equivalents match core electrical specifications but may vary in ESR or ripple current ratings while maintaining functional compatibility.

All substitute parts share identical physical dimensions (6.30 mm diameter, 8.00 mm height), land size (6.60 mm × 6.60 mm), and surface mount package configuration, ensuring PCB layout compatibility without redesign.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (16 V Applications):

EEE-TC1C101XP (Panasonic) and EMHJ160ARA101MF80G (Chemi-Con) are preferred direct substitutes. Both maintain identical ESR (450 mOhm @ 100 kHz), active product status, and AEC-Q200 automotive qualification. These parts provide the highest compatibility with existing designs.

16THV100M6.3X8 (Rubycon) is a functional equivalent with higher ESR (700 mOhm @ 100 kHz) and active status with AEC-Q200 rating. This part is suitable where ESR tolerance permits.

VUP101M1CTR-0607S (SURGE) provides parametric equivalence with slightly elevated ESR (500 mOhm) and active status. General purpose rating applies; automotive qualification is not specified.

For Voltage Upgrade Applications:

UCH1V101MCL1GS (Nichicon, 35 V) and EEE-TQV101XAP (Panasonic, 35 V) offer superior voltage margin with reduced ESR (300 mOhm @ 100 kHz) and active product status. Both carry AEC-Q200 certification. These are suitable for new designs requiring higher voltage headroom.

UCZ1E101MCS6GS (Nichicon, 25 V) provides intermediate voltage upgrade but retains "Not For New Designs" status and should be avoided for new applications.

Compliance Considerations:

All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part. Parts with AEC-Q200 certification are recommended for automotive and high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 25 V or 35 V rated capacitor in place of the 16 V UCZ1C101MCS6GS?

A: Yes. Higher voltage-rated capacitors are backward-compatible with lower voltage applications. The 25 V (UCZ1E101MCS6GS) and 35 V (UCH1V101MCL1GS, EEE-TQV101XAP) variants maintain the same 100 µF capacitance and physical dimensions, allowing direct PCB substitution. The 35 V options additionally provide lower ESR (300 mOhm vs. 450 mOhm), improving performance in ripple-current-sensitive circuits.

Q: What is the significance of ESR differences between substitute parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat dissipation. Lower ESR values (300 mOhm) reduce power loss and thermal stress. The original part and most direct substitutes specify 450 mOhm ESR. The 16THV100M6.3X8 (700 mOhm) has higher ESR and may generate more heat under high ripple current conditions. Selection depends on circuit ripple current requirements.

Q: Are all substitute parts suitable for automotive applications?

A: Parts carrying AEC-Q200 certification (16THV100M6.3X8, EEE-TC1C101XP, EMHJ160ARA101MF80G, UCH1V101MCL1GS, EEE-TQV101XAP) meet automotive qualification standards. VUP101M1CTR-0607S and UCZ1E101MCS6GS lack this certification and should be evaluated against specific automotive requirements.

Q: Will substitute parts require PCB layout changes?

A: No. All substitute parts share identical physical dimensions (6.30 mm diameter, 8.00 mm height) and land size (6.60 mm × 6.60 mm). PCB footprints and assembly processes remain unchanged.

Q: Why is the original UCZ1C101MCS6GS marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status and is no longer recommended for new product development. Active alternatives from Panasonic (EEE-TC1C101XP), Rubycon (16THV100M6.3X8), and Chemi-Con (EMHJ160ARA101MF80G) should be used for new designs.

Q: What is the difference between "Direct," "Upgrade," and "Parametric Equivalent" classifications?

A: Direct equivalents match the original 16 V rating and electrical specifications. Upgrade substitutes provide higher voltage ratings (25 V or 35 V) with improved performance margins. Parametric equivalents maintain core electrical function but may vary in secondary parameters such as ESR or ripple current ratings.
