Substitute Part Grouping Explanation

Substitute parts for the 336CKE050M are qualified based on the following criteria:

Electrical Equivalence: All substitute parts match the primary electrical specifications: 33 µF capacitance, 50 V rated voltage, and ±20% tolerance. All parts maintain the same polarization (polar) and operating temperature range of -40°C to 105°C.

Mechanical Compatibility: All substitute parts share identical lead spacing (0.079" / 2.00 mm), package diameter (0.197" / 5.00 mm), and maximum seated height (0.492" / 12.50 mm). All are through-hole mounted in radial, can package configuration.

Thermal Lifetime: The 336CKE050M specifies 2000 hours @ 105°C. Direct substitutes (ESH336M050AC3AA and UKA1H330MDD) match this specification exactly. The upgrade substitute (50YXJ33M5X11) provides an extended lifetime of 5000 hours @ 105°C, representing improved thermal performance.

Regulatory Compliance: All parts are ROHS3 compliant and REACH unaffected, matching the main part's compliance status.

Engineering Selection Recommendations

Direct Substitutes (Equivalent Replacement):

ESH336M050AC3AA (KEMET) and UKA1H330MDD (Nichicon) are direct electrical and mechanical equivalents to the 336CKE050M. Both parts match all critical parameters including capacitance, voltage rating, tolerance, thermal lifetime, and package dimensions. ESH336M050AC3AA is recommended for new designs due to its Active product status and current availability (18,064 pcs in stock). UKA1H330MDD carries an Obsolete product status and should be used only for legacy system maintenance or repair applications where original part continuity is required.

Upgrade Substitute (Enhanced Performance):

50YXJ33M5X11 (Rubycon) provides an upgrade path with extended thermal lifetime of 5000 hours @ 105°C compared to the 2000-hour specification of the main part. This part maintains all electrical and mechanical compatibility while offering improved reliability in high-temperature environments. The part is Active and widely available (12,277 pcs in stock).

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original 336CKE050M specification.

Frequently Asked Questions (FAQ)

Q: Can ESH336M050AC3AA replace 336CKE050M in existing designs?

A: Yes. ESH336M050AC3AA matches all electrical specifications (33 µF, 50 V, ±20% tolerance, 2000 Hrs @ 105°C) and mechanical parameters (lead spacing, package diameter, height, through-hole mounting). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between direct substitutes and the upgrade substitute?

A: Direct substitutes (ESH336M050AC3AA and UKA1H330MDD) match the 2000-hour thermal lifetime of the 336CKE050M. The upgrade substitute (50YXJ33M5X11) extends thermal lifetime to 5000 hours @ 105°C while maintaining all other specifications. The upgrade is suitable for applications requiring enhanced thermal endurance.

Q: Why is UKA1H330MDD marked as Obsolete?

A: UKA1H330MDD carries an Obsolete product status from Nichicon. This part should be used only for repair or maintenance of legacy systems. For new designs, ESH336M050AC3AA or 50YXJ33M5X11 are recommended as Active alternatives.

Q: Are all substitute parts through-hole mounted?

A: Yes. All substitute parts use through-hole mounting with identical lead spacing (0.079" / 2.00 mm) and package form factor (radial, can). No PCB layout modifications are required for substitution.

Q: Do substitute parts have different ripple current ratings?

A: Ripple current specifications are not uniformly provided across all parts in the substitute list. The main part 336CKE050M specifies 100 mA @ 120 Hz and 230 mA @ 100 kHz. When ripple current performance is critical to the application, consult detailed datasheets for each substitute part.

Q: Are all parts RoHS3 compliant?

A: Yes. All parts listed (336CKE050M, ESH336M050AC3AA, UKA1H330MDD, and 50YXJ33M5X11) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
