Substitute Part Grouping Explanation

Substitution eligibility is determined by strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

Capacitance: 33 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.295" (7.50mm) (exact match required)
Case Diameter: 0.630" (16.00mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Secondary Compatibility Parameters:

Operating Temperature Range: Must support minimum -25°C ~ 85°C
Lifetime Rating: Minimum 2000 Hrs @ 85°C or equivalent thermal performance
Ripple Current Capability: Must meet or exceed application requirements

All substitute parts listed meet the primary substitution criteria. Variations in height, ESR, ripple current ratings, and thermal lifetime represent performance enhancements or alternative specifications within the same functional category.

Engineering Selection Recommendations

Direct Substitutes (Equivalent Performance): 336CKS450M, 336CKS450MQV, ECA-2WM330, and SK330M450ST are direct functional equivalents meeting all primary electrical and mechanical parameters. All substitute parts are active products with ROHS3 compliance, addressing the obsolescence of the UVR2W330MHA. Selection among these options depends on height constraints and ripple current requirements specific to the application.

Upgraded Alternatives (Enhanced Performance): MAL215257339E3 and MAL215267339E3 (Vishay Beyschlag, 152 RMH series) provide extended thermal performance with 4000 hours lifetime at 105°C and expanded operating temperature range (-40°C ~ 105°C). These parts carry AEC-Q200 automotive qualification and are suitable for applications requiring enhanced reliability. Height and footprint remain compatible with the original specification.

Compliance Consideration: All substitute parts are ROHS3 compliant, whereas the original UVR2W330MHA is RoHS non-compliant. This compliance upgrade is standard across active replacement inventory and reflects current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different height dimensions? A: Yes. All listed substitutes maintain the required 0.295" (7.50mm) lead spacing and 0.630" (16.00mm) case diameter. Height variations (ranging from 1.043" to 1.496") are acceptable provided PCB layout and enclosure clearance accommodate the specific part selected. Verify height constraints in your mechanical design before final selection.

Q: What is the difference between direct substitutes and upgraded alternatives? A: Direct substitutes (336CKS450M, 336CKS450MQV, ECA-2WM330, SK330M450ST) maintain identical thermal ratings (2000 Hrs @ 85°C) and operating temperature range (-25°C ~ 85°C) as the original part. Upgraded alternatives (MAL215257339E3, MAL215267339E3) extend thermal lifetime to 4000 Hrs @ 105°C and operating range to -40°C ~ 105°C, suitable for demanding thermal environments or automotive applications.

Q: Are all substitutes RoHS compliant? A: Yes. All listed substitute parts are ROHS3 compliant. The original UVR2W330MHA is RoHS non-compliant. Substitution automatically upgrades compliance status to current regulatory standards.

Q: What parameters must remain identical for substitution? A: Capacitance (33 µF), voltage rating (450 V), tolerance (±20%), polarization (polar), lead spacing (7.50mm), case diameter (16.00mm), and mounting type (through hole) must remain unchanged. These parameters define electrical and mechanical compatibility with the original circuit design.

Q: Can I substitute based on ripple current ratings alone? A: No. Ripple current capability is a secondary parameter. Primary substitution criteria (capacitance, voltage, tolerance, lead spacing, case diameter, mounting type) must match exactly. Ripple current variations among substitutes reflect design differences but do not affect basic functional compatibility.

Q: Which substitute offers the best thermal performance? A: MAL215257339E3 and MAL215267339E3 provide the highest thermal performance with 4000 hours lifetime at 105°C and AEC-Q200 automotive qualification. These are appropriate for applications requiring extended reliability or operation in elevated temperature environments.
