Substitute Part Grouping Explanation

Substitution eligibility for the 335CKE100M is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 3.3 µF
• Voltage Rating: 100 V
• Tolerance: ±20%
• Package Type: Radial, Can
• Mounting Type: Through Hole
• Lead Spacing: 0.079" (2.00mm)
• Physical Dimensions: 0.197" Dia (5.00mm), Height 0.492" (12.50mm) maximum
• Polarization: Polar

Acceptable Variation Parameters:

• Operating Temperature Range: Must encompass or equal the original specification
• Lifetime @ Temperature: May exceed the original specification
• ESR and Impedance: May vary within acceptable electrical performance
• Ripple Current: May vary based on frequency and application requirements

The identified substitute parts maintain all mandatory parameters while offering variations in performance characteristics that do not compromise functional compatibility in bypass and decoupling applications.

Engineering Selection Recommendations

335CKE100M (Cornell Dubilier / Illinois Capacitor)

• Product Status: Active
• Compliance: ROHS3 Compliant, REACH Unaffected
• Selection Basis: Primary choice for new designs requiring active product status and standard performance characteristics in bypass and decoupling applications.

UPM2A3R3MDD (Nichicon)

• Product Status: Obsolete
• Compliance: ROHS3 Compliant, REACH Unaffected, AEC-Q200 Rated
• Selection Basis: Suitable for replacement in existing designs where automotive-grade qualification (AEC-Q200) is required. Extended operating temperature range (-55°C to 105°C) provides additional thermal margin. Not recommended for new designs due to obsolete status.

100YXJ3.3M5X11 (Rubycon)

• Product Status: Active
• Compliance: ROHS3 Compliant, REACH Unaffected
• Selection Basis: Recommended for applications requiring extended lifetime performance. The 5000-hour rating at 105°C provides 2.5× longer operational life compared to the primary part. Lower impedance (2.7 Ohms) and reduced ripple current requirements support high-frequency decoupling applications. Suitable for new designs and long-term reliability requirements.

Frequently Asked Questions (FAQ)

Q: Can UPM2A3R3MDD be used as a direct replacement for 335CKE100M?

A: UPM2A3R3MDD maintains all mandatory electrical and mechanical parameters: 3.3 µF capacitance, 100 V rating, ±20% tolerance, identical package dimensions, and 2.00mm lead spacing. However, the part is classified as Obsolete. For new designs, use an Active product. For existing designs requiring replacement, UPM2A3R3MDD is electrically compatible.

Q: What is the advantage of 100YXJ3.3M5X11 over 335CKE100M?

A: The 100YXJ3.3M5X11 offers extended lifetime (5000 hours at 105°C versus 2000 hours) and lower impedance (2.7 Ohms versus 40.19 Ohms ESR). These characteristics improve performance in high-frequency decoupling and reduce thermal stress in long-duration applications. Both parts are Active and ROHS3 compliant.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share identical package specifications: 0.197" diameter (5.00mm), 0.492" maximum seated height (12.50mm), and 0.079" lead spacing (2.00mm). Direct PCB footprint compatibility is confirmed.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range does not restrict substitution. UPM2A3R3MDD extends the lower limit to -55°C, providing additional thermal margin. For applications operating within -40°C to 105°C, all three parts are functionally equivalent.

Q: Which part should be selected for automotive applications?

A: UPM2A3R3MDD carries AEC-Q200 automotive qualification. If automotive-grade certification is required, this part is the specified choice. Both 335CKE100M and 100YXJ3.3M5X11 do not carry automotive ratings.

Q: How does ripple current rating affect part selection?

A: Ripple current specifications vary: 335CKE100M (35 mA @ 120 Hz), UPM2A3R3MDD (27 mA @ 120 Hz), and 100YXJ3.3M5X11 (16.8 mA @ 120 Hz). For bypass and decoupling applications with low ripple current requirements, 100YXJ3.3M5X11 is suitable. For higher ripple current demands, 335CKE100M provides greater capacity.
