Engineering Selection Recommendations

Primary Part: 336SML025MD5

The Cornell Dubilier 336SML025MD5 maintains Active product status and is the preferred selection when available. This part carries full manufacturer support and established supply chain presence with 620 units in current inventory.

Substitute Part: UWR1E330MCL1GB

The Nichicon UWR1E330MCL1GB is a direct parametric equivalent suitable for applications where the primary part is unavailable. This substitute carries Obsolete product status; however, it maintains full electrical and mechanical equivalence with identical capacitance, voltage rating, tolerance, temperature range, and lifetime specifications. Both parts are RoHS3 compliant with MSL 1 rating.

The substitute part demonstrates superior ripple current performance at 120 Hz (52 mA versus 46 mA), which provides additional operational margin in applications subject to AC ripple stress. Physical footprint and land pattern compatibility are identical, permitting direct PCB layout substitution without design modification.

Selection between these parts should be based on availability and supply chain considerations. Both parts satisfy the specified electrical and mechanical requirements for general-purpose aluminum electrolytic capacitor applications in the 33 µF, 25 V category.

Frequently Asked Questions (FAQ)

Q: Can the UWR1E330MCL1GB replace the 336SML025MD5 in existing designs?

A: Yes. The UWR1E330MCL1GB is a direct parametric equivalent with identical capacitance (33 µF), voltage rating (25 V), tolerance (±20%), operating temperature range (-40°C ~ 85°C), and lifetime specification (2000 Hrs @ 85°C). Physical dimensions and surface mount land pattern are identical, permitting direct substitution without PCB layout modification.

Q: What is the difference in ripple current performance?

A: The UWR1E330MCL1GB demonstrates higher ripple current capability at 120 Hz (52 mA) compared to the 336SML025MD5 (46 mA). This represents a 13% increase in ripple current handling capacity and provides additional operational margin in applications subject to AC ripple stress.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 336SML025MD5 and UWR1E330MCL1GB are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting identical environmental and regulatory requirements.

Q: What is the significance of the Obsolete product status for the Nichicon part?

A: The UWR1E330MCL1GB carries Obsolete product status, indicating that Nichicon has discontinued active manufacturing and support for this specific part number. However, the part remains functionally equivalent and is available through existing inventory channels. Selection should prioritize the Active-status 336SML025MD5 when supply permits.

Q: Are the surface mount land patterns identical?

A: Yes. Both parts utilize identical surface mount land size specifications of 0.209" L x 0.209" W (5.30mm x 5.30mm), with matching physical dimensions of 0.197" diameter and 0.217" maximum seated height. Direct PCB footprint compatibility is confirmed.

Q: What applications are these capacitors suitable for?

A: Both parts are classified for general-purpose applications. The 33 µF, 25 V rating with 2000-hour lifetime at 85°C makes these capacitors suitable for power supply filtering, decoupling, and energy storage functions in consumer and industrial electronics operating within the specified temperature range.
