Substitute Part Grouping Explanation

Substitution for the UWS1V101MCL1GS is determined by the following critical parameters:

Capacitance: 100 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 35 V minimum (equal or higher voltage ratings are acceptable)
Lifetime @ Temperature: 2000 Hrs @ 85°C minimum (equal or longer lifetime acceptable)
Operating Temperature Range: -40°C ~ 85°C (must match or exceed)
Mounting Type: Surface Mount (exact match required)
Package / Case: Radial, Can - SMD (exact match required)
Physical Dimensions: Compatible footprint (8.00mm diameter, 10.50mm height maximum, or smaller compatible sizes)
Ripple Current Ratings: Must meet or exceed specified values at 120 Hz and 10 kHz

Substitute parts are grouped into two categories:

Direct Equivalents (Same Voltage Rating - 35 V): Parts with identical electrical specifications and compatible physical dimensions.

Upgraded Substitutes (Higher Voltage Rating - 50 V): Parts with 50 V voltage rating, which provide enhanced voltage margin while maintaining all other critical parameters. These are electrically compatible and physically compatible with the original footprint.

Engineering Selection Recommendations

For Direct Replacement (Same Voltage - 35 V):

UUR1V101MNL1GS (Nichicon) is the primary equivalent, offering identical electrical specifications and physical dimensions to the UWS1V101MCL1GS. Both are obsolete products from the same manufacturer with matching 2000-hour lifetime ratings at 85°C.

EEE-1VA101UP (Panasonic Electronic Components) provides a compatible 35 V substitute with matching 2000-hour lifetime and RoHS compliance. Physical dimensions are slightly different (8.00mm x 10.20mm vs. 8.00mm x 10.50mm), but the footprint remains compatible for surface mount applications.

For Upgraded Voltage Rating (50 V):

EDK107M050A9MAA (KEMET) is an active product offering 50 V rating with enhanced ripple current performance (200 mA @ 120 Hz, 250 mA @ 10 kHz). This part provides superior voltage margin and is currently in active production with ROHS3 compliance.

EMVA500ADA101MHA0G (Chemi-Con) offers 50 V rating with ROHS3 compliance, though it is classified as Last Time Buy. Physical height is slightly reduced (10.00mm vs. 10.50mm), maintaining footprint compatibility.

For Space-Constrained Applications:

UUR1V101MCL6GS (Nichicon) provides a smaller footprint option (6.30mm x 8.00mm) with identical 35 V rating and 2000-hour lifetime. Ripple current ratings are reduced (132 mA @ 120 Hz, 171.6 mA @ 10 kHz), requiring verification that application requirements are met.

Product Status Considerations:

EEE-1VA101UAP (Panasonic) is the only active product among 35 V direct equivalents, though it has a reduced lifetime rating of 1000 hours at 85°C compared to the original 2000 hours. This part is suitable for new designs requiring active component availability.

EDK107M050A9MAA (KEMET) is the only active product among all substitutes, making it the preferred choice for new production requiring long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can I use a 50 V rated capacitor in place of the 35 V UWS1V101MCL1GS?

A: Yes. A 50 V rated capacitor is electrically compatible with a 35 V application. The higher voltage rating provides additional safety margin and does not negatively affect circuit performance. EDK107M050A9MAA and EMVA500ADA101MHA0G are both qualified 50 V substitutes with identical 100 µF capacitance and ±20% tolerance.

Q: What is the difference between UUR1V101MNL1GS and UUR1V101MCL6GS?

A: Both are Nichicon UUR series parts with 100 µF, 35 V specifications. The primary difference is physical size: UUR1V101MNL1GS is 8.00mm diameter x 10.50mm height (matching the original), while UUR1V101MCL6GS is 6.30mm diameter x 8.00mm height. The smaller part has reduced ripple current ratings (132 mA @ 120 Hz vs. 175 mA). Select based on available PCB space and ripple current requirements.

Q: Why do some substitutes have different ripple current ratings?

A: Ripple current capacity is determined by physical size and internal construction. Smaller packages (such as UUR1V101MCL6GS at 6.30mm) have lower ripple current ratings. Larger packages (such as AVS107M35G24T-F and EEE-1VA101AP at 10.00mm) have higher ripple current ratings. Verify that the selected substitute meets the ripple current requirements of your specific application.

Q: Is EEE-1VA101UAP suitable for applications requiring 2000-hour lifetime?

A: No. EEE-1VA101UAP has a rated lifetime of 1000 hours at 85°C, compared to the original 2000-hour specification. This part is suitable only for applications with lower lifetime requirements. For 2000-hour lifetime requirements, select EEE-1VA101UP or equivalent parts with matching lifetime ratings.

Q: What is the difference between "Obsolete" and "Not For New Designs" product status?

A: Obsolete parts are no longer manufactured and available only from existing inventory. Not For New Designs parts are still manufactured but are being phased out; they should not be used in new product designs. Active products (such as EDK107M050A9MAA and EEE-1VA101UAP) are currently in production and recommended for new designs.

Q: Are all substitute parts RoHS compliant?

A: Most substitutes listed are ROHS3 compliant. Verify specific RoHS status for your application requirements. EDK107M050A9MAA, EMVA500ADA101MHA0G, AVS107M35G24T-F, and AVS107M35F24T-F are confirmed ROHS3 compliant. EEE-1VA101UAP is ROHS3 compliant. EEE-1VA101UP, EEE-1VA101AP, and EEE-1VA101P are RoHS compliant.

Q: Can I substitute a smaller package capacitor if my PCB has space constraints?

A: Yes, if the smaller package meets your electrical requirements. UUR1V101MCL6GS (6.30mm x 8.00mm) is a smaller alternative, but verify that its reduced ripple current ratings (132 mA @ 120 Hz, 171.6 mA @ 10 kHz) are sufficient for your application. Confirm PCB land pattern compatibility before implementation.
