Substitute Part Grouping Explanation

Substitution eligibility for the UCS2C330MPD is determined by the following core parameters:

Capacitance Value: Must be 33 µF (exact match required)
Tolerance: Must be ±20% or tighter
Voltage Rating: Must be equal to or greater than 160 V
Package Configuration: Must be Radial, Can with Through Hole mounting
Lead Spacing: Must be 0.197" (5.00 mm)
Physical Dimensions: Must match 0.394" Dia × 0.846" Height (Max)
Polarization: Must be Polar
Operating Temperature Range: Must support -40°C ~ 105°C minimum

Two substitute parts meet these criteria:

UCS2D330MPD (Nichicon): Identical to the main part except voltage rating is upgraded to 200 V, maintaining all other specifications within allowable parameters.
EKXJ251ELL330MJ20S (Chemi-Con): Meets all core substitution parameters with voltage rating upgraded to 250 V and extended lifetime of 10000 Hrs @ 105°C. Includes AEC-Q200 automotive qualification.

Engineering Selection Recommendations

UCS2D330MPD is a direct upgrade path within the Nichicon UCS series. It maintains identical electrical performance and thermal characteristics while providing a 40 V higher voltage margin (200 V vs. 160 V). This substitution is suitable for applications requiring enhanced voltage headroom without changing component footprint or thermal behavior.

EKXJ251ELL330MJ20S represents a cross-manufacturer upgrade option from Chemi-Con's KXJ series. This part provides the highest voltage rating (250 V) and extended operational lifetime (10000 Hrs @ 105°C vs. 8000 Hrs). The inclusion of AEC-Q200 automotive qualification indicates suitability for automotive-grade applications. The ripple current capacity at 100 kHz is 600 mA, which is 50 mA lower than the main part; this must be verified against circuit requirements.

All three parts maintain ROHS3 compliance and identical physical dimensions, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can UCS2D330MPD be used as a direct replacement for UCS2C330MPD?

A: Yes. UCS2D330MPD is a direct substitute with identical capacitance, tolerance, package, and thermal specifications. The 200 V rating provides additional voltage margin over the 160 V requirement.

Q: What is the primary difference between UCS2D330MPD and EKXJ251ELL330MJ20S?

A: Both are functionally equivalent at 33 µF ±20%. UCS2D330MPD is a Nichicon part rated 200 V with 8000 Hrs lifetime. EKXJ251ELL330MJ20S is a Chemi-Con part rated 250 V with 10000 Hrs lifetime and AEC-Q200 automotive qualification. The Chemi-Con part has slightly lower ripple current capacity (600 mA vs. 650 mA @ 100 kHz).

Q: Are all three parts physically identical?

A: Yes. All three parts share identical lead spacing (5.00 mm), case diameter (10.00 mm), and maximum height (21.50 mm), ensuring direct PCB footprint compatibility.

Q: Which substitute should be selected for automotive applications?

A: EKXJ251ELL330MJ20S includes AEC-Q200 automotive qualification and is the appropriate choice for automotive-grade circuit designs.

Q: Does the lower ripple current of EKXJ251ELL330MJ20S affect compatibility?

A: Ripple current capacity must be verified against circuit requirements. EKXJ251ELL330MJ20S provides 600 mA @ 100 kHz compared to 650 mA for the other parts. If the circuit requires ripple current handling above 600 mA, this part is not suitable.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected.
