Engineering Selection Recommendations

Direct Equivalent (Same Voltage, Same Footprint): UVR0J101MDD is the direct equivalent with identical electrical specifications and mechanical dimensions. It maintains the same 6.3 V rating and 2000 Hrs @ 85°C lifetime. The primary difference is RoHS3 compliance and improved availability (12,371 units in stock versus 678 units for the original part).

Voltage Upgrade Substitutes (Same Footprint, Higher Voltage): UKW1A101MDD and UHE1A101MDD are pin-compatible upgrades with 10 V ratings. Both maintain the 0.433" (11.00mm) height and 0.079" (2.00mm) lead spacing. UHE1A101MDD offers extended lifetime (4000 Hrs @ 105°C) and wider operating temperature range (-40°C ~ 105°C), providing enhanced reliability in the same physical footprint.

Extended Temperature Range Substitutes: UPW0J101MDD maintains the 6.3 V rating while extending the operating temperature range to -55°C ~ 105°C and lifetime to 2000 Hrs @ 105°C. This part is suitable for applications requiring wider temperature performance.

Cross-Manufacturer Active Alternatives: 107SAK010M (Cornell Dubilier), EEU-EB1A101S (Panasonic), and EKZE100ELL101ME11D (Chemi-Con) are active products with 10 V ratings. These parts provide long-term availability and ROHS3 compliance. EEU-EB1A101S offers the highest lifetime rating (5000 Hrs @ 105°C) among all substitutes.

RoHS Compliance Consideration: The original UVR0J101MDA is RoHS non-compliant. All recommended substitutes are ROHS3 compliant, meeting current regulatory requirements for new designs and manufacturing.

Frequently Asked Questions (FAQ)

Q: Can I use a 10 V rated capacitor in place of the 6.3 V UVR0J101MDA? A: Yes. A 10 V capacitor is electrically compatible as an upgrade. The higher voltage rating provides additional safety margin and does not affect circuit operation when the applied voltage remains at or below 6.3 V. All mechanical parameters (lead spacing, size, mounting type) must remain identical.

Q: What is the difference between UVR0J101MDA and UVR0J101MDD? A: Both parts have identical electrical specifications (100 µF, 6.3 V, ±20%, 2000 Hrs @ 85°C). The primary differences are: UVR0J101MDD is RoHS3 compliant (the original is not), has a slightly taller height (0.492" versus 0.433"), and has significantly higher inventory availability (12,371 units versus 678 units).

Q: Why do some substitutes have different heights? A: Height variation occurs due to manufacturing design changes across different series and manufacturers. Verify PCB clearance before substitution. Parts with identical lead spacing (0.079" / 2.00mm) and diameter (0.197" / 5.00mm) are mechanically compatible, but height differences may require board layout verification.

Q: Is UHE1A101MDD a better choice than UKW1A101MDD? A: UHE1A101MDD offers superior performance with 4000 Hrs @ 105°C lifetime versus 2000 Hrs @ 85°C for UKW1A101MDD. Both maintain identical mechanical compatibility. UHE1A101MDD is recommended for applications requiring extended reliability and wider operating temperature range (-40°C ~ 105°C).

Q: Can I use Panasonic EEU-EB1A101S or Chemi-Con EKZE100ELL101ME11D as substitutes? A: Yes. Both are active products with 10 V ratings, 100 µF capacitance, and ±20% tolerance. They maintain through-hole radial can package with 0.079" (2.00mm) lead spacing. Verify height clearance: EEU-EB1A101S is 0.472" (12.00mm) and EKZE100ELL101ME11D is 0.492" (12.50mm). Both are ROHS3 compliant with extended temperature ranges.

Q: What does "Obsolete" product status mean for the original part? A: Obsolete status indicates the manufacturer has discontinued production. Existing inventory may be available from distributors, but long-term supply is not guaranteed. Active substitute parts (107SAK010M, EEU-EB1A101S, EKZE100ELL101ME11D) provide assured long-term availability for new designs and ongoing production.

Q: Are all substitutes pin-compatible with the original UVR0J101MDA? A: All listed substitutes maintain the same lead spacing (0.079" / 2.00mm) and diameter (0.197" / 5.00mm), ensuring pin compatibility. Height differences require PCB clearance verification. Electrical compatibility is confirmed for all parts with identical or higher voltage ratings.
