Engineering Selection Recommendations

For Direct Replacement (Equivalent Performance): Select from Active status parts with matching electrical specifications: 100YXJ1M5X11 (Rubycon), 105CKE100M (Cornell Dubilier), or 105KXM100M (Cornell Dubilier). These parts maintain the 1 µF, 100 V, ±20% tolerance specification with identical package geometry and through-hole mounting. All are ROHS3 compliant and REACH unaffected.

For Enhanced Performance (Upgrade): UKL2A010KDD (Nichicon) provides tighter ±10% tolerance. EKYA101ELL1R0ME11D (Chemi-Con) and ESL105M100AC3AA (KEMET) offer extended lifetime ratings (5000 and 8000 hours respectively at 105°C) with wider operating temperature ranges. ESL105M100AC3AA provides the longest service life at 8000 hours @ 105°C.

For Space-Constrained Applications: 515D105M100JA6AE3 (Vishay Sprague) features a reduced height of 0.433" (11.00 mm) while maintaining all electrical specifications, though it is obsolete status.

For Active Production: Prioritize Active status parts: 100YXJ1M5X11, 105CKE100M, 105KXM100M, EKYA101ELL1R0ME11D, ESH105M100AC3AA, ESL105M100AC3AA, SK010M100ST, and 100PK1MEFC5X11. All are ROHS3 compliant and suitable for new designs.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with ±10% tolerance instead of ±20%? A: Yes. UKL2A010KDD offers ±10% tolerance, which is tighter than the original ±20% specification. This represents an upgrade in tolerance performance and is electrically compatible.

Q: What is the difference between Direct, Upgrade, Similar, and Parametric Equivalent classifications? A: Direct substitutes match the original part's electrical and mechanical specifications. Upgrade parts offer improved specifications such as tighter tolerance, extended lifetime, or wider operating temperature range. Similar parts have minor variations in height or other non-critical parameters. Parametric Equivalent parts match core electrical and mechanical specifications with acceptable variations in secondary parameters.

Q: Does the height variation in SK010M100ST (0.512" vs. 0.492") affect compatibility? A: Height variation must be evaluated against PCB layout constraints. SK010M100ST is 0.020" taller than the original. Verify clearance in your specific application before substitution.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the original UVR2A010MDD compliance status.

Q: Which substitute offers the longest operational life? A: ESL105M100AC3AA (KEMET) provides 8000 hours @ 105°C, the longest lifetime rating among all substitutes. This part also features the lowest ESR at 1.85 Ohm @ 100 kHz.

Q: Can I substitute an obsolete part with another obsolete part? A: Obsolete parts (UKL2A010KDD, 515D105M100JA6AE3) should be avoided for new designs. Prioritize Active status parts for production continuity and long-term availability.

Q: What is the significance of operating temperature range differences? A: The original part operates -40°C to 85°C. Substitutes with -40°C to 105°C range provide wider thermal operating margin. This is beneficial for applications exposed to elevated ambient temperatures or thermal cycling.
