Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full compliance with RoHS3 and REACH requirements, matching the regulatory status of the 105CKE100M. All parts are classified as Active product status, ensuring continued availability and support.

ESH105M100AC3AA (KEMET): Direct equivalent with identical 2000-hour lifetime rating at 105°C. Suitable for direct replacement in applications where the original specification is maintained. Higher inventory availability (32,377 units) supports supply chain continuity.

ESL105M100AC3AA (KEMET): Enhanced performance option with 8000-hour lifetime at 105°C and significantly lower ESR (1.85Ohm @ 100kHz). Increased ripple current handling (52.5 mA @ 120 Hz, 105 mA @ 100 kHz) supports applications requiring improved thermal performance. Substantial inventory (29,252 units) ensures availability.

100YXJ1M5X11 (Rubycon): Upgrade option with 5000-hour lifetime at 105°C. Suitable for applications requiring extended operational life beyond the baseline 2000-hour specification. Lower ripple current ratings indicate suitability for lower-stress applications.

EKYA101ELL1R0ME11D (Chemi-Con): Upgrade option with 5000-hour lifetime at 105°C. Mechanical and electrical parameters align with upgrade requirements. Inventory availability (4,955 units) supports procurement planning.

Frequently Asked Questions (FAQ)

Q: Can ESH105M100AC3AA be used as a direct replacement for 105CKE100M?

A: Yes. ESH105M100AC3AA maintains identical electrical specifications (1 µF, 100 V, ±20% tolerance), operating temperature range (-40°C to 105°C), and mechanical dimensions (0.197" Dia, 0.492" height, 0.079" lead spacing). Both parts share the same 2000-hour lifetime rating at 105°C and are ROHS3 compliant.

Q: What is the difference between ESL105M100AC3AA and the original 105CKE100M?

A: ESL105M100AC3AA provides enhanced performance characteristics: 8000-hour lifetime at 105°C (versus 2000 hours), significantly lower ESR at 1.85Ohm @ 100kHz, and higher ripple current capacity. All core electrical and mechanical parameters remain identical. This part is suitable for applications requiring improved thermal stability and lower impedance.

Q: Are the Rubycon 100YXJ1M5X11 and Chemi-Con EKYA101ELL1R0ME11D considered upgrades?

A: Both parts offer extended lifetime (5000 hours at 105°C versus 2000 hours). They maintain identical capacitance, voltage rating, tolerance, and mechanical form factor. Selection depends on application requirements for operational life and thermal performance.

Q: Do all substitute parts fit the same PCB footprint as 105CKE100M?

A: Yes. All substitute parts share identical mechanical specifications: 0.197" diameter, 0.492" maximum seated height, and 0.079" lead spacing. Through-hole mounting type and radial can package are consistent across all parts.

Q: Are there compliance differences between the main part and substitutes?

A: No. All parts are ROHS3 compliant and REACH unaffected. Regulatory compliance is uniform across the 105CKE100M and all listed substitute parts.

Q: Which substitute part should be selected for high-ripple-current applications?

A: ESL105M100AC3AA supports the highest ripple current specifications: 52.5 mA @ 120 Hz and 105 mA @ 100 kHz. This part is engineered for applications requiring superior ripple current handling.

Q: Can substitute parts be mixed in the same circuit design?

A: All substitute parts meet the core electrical and mechanical requirements for the 105CKE100M application category. Circuit design compatibility depends on specific application parameters. Substitution within the same functional category maintains electrical equivalence.
