Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UUR0G331MCL1GS is determined by the following critical parameters:

• Capacitance Value: 330 µF (exact match required)
• Voltage Rating: 4 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - SMD (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Compliance: ROHS3 Compliant (required for regulatory alignment)
• Moisture Sensitivity Level: 1 (Unlimited) (required for handling compatibility)

Two substitute parts meet these criteria:

UWT0G331MCL1GS (MFR Recommended): Active product status with enhanced operating temperature range (-55°C ~ 105°C) and higher temperature lifetime rating (1000 Hrs @ 105°C). Identical capacitance, voltage, tolerance, package, and mounting specifications.

UWX0G331MCL1GB (Similar): Obsolete product with matching capacitance, voltage, tolerance, and package specifications. Physical dimensions differ from the main part, requiring PCB layout verification.

Parameter Comparison

Engineering Selection Recommendations

UWT0G331MCL1GS is the primary substitute option. This part maintains identical electrical specifications (330 µF, 4 V, ±20% tolerance) and identical land size footprint (0.260" L x 0.260" W). The active product status ensures long-term availability and supply chain continuity. The extended operating temperature range (-55°C ~ 105°C) provides broader environmental compatibility compared to the obsolete UUR0G331MCL1GS. Height difference (0.303" vs 0.240") requires PCB clearance verification but does not affect electrical performance.

UWX0G331MCL1GB is a secondary substitute option suitable only when PCB layout permits accommodation of larger physical dimensions (0.315" diameter, 8.00mm vs 6.30mm; 0.327" land size vs 0.260"). This part is obsolete and should be considered only when UWT0G331MCL1GS is unavailable. The larger package footprint necessitates complete PCB layout review before implementation.

Both substitutes maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and handling compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can UWT0G331MCL1GS be used as a direct replacement for UUR0G331MCL1GS?

A: UWT0G331MCL1GS is electrically equivalent with identical capacitance (330 µF), voltage rating (4 V), tolerance (±20%), and land size footprint (0.260" L x 0.260" W). The primary consideration is seated height: UWT0G331MCL1GS measures 0.303" (7.70mm) versus UUR0G331MCL1GS at 0.240" (6.10mm). PCB clearance must be verified to confirm physical fit.

Q: What is the difference between UWT0G331MCL1GS and UWX0G331MCL1GB?

A: Both parts share identical electrical specifications (330 µF, 4 V, ±20%). UWT0G331MCL1GS has active product status and smaller physical dimensions (0.248" diameter, 6.60mm land size). UWX0G331MCL1GB is obsolete with larger physical dimensions (0.315" diameter, 8.30mm land size). UWT0G331MCL1GS is the preferred choice due to active availability and smaller footprint.

Q: Are there PCB layout changes required when substituting to UWT0G331MCL1GS?

A: Land size footprint remains identical (0.260" L x 0.260" W), so solder pad layout does not require modification. Vertical clearance must be evaluated: UWT0G331MCL1GS is 0.063" (1.60mm) taller than the original part. Confirm that component height does not interfere with adjacent components or enclosure constraints.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. UWT0G331MCL1GS and UWX0G331MCL1GB are both ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original UUR0G331MCL1GS specification.

Q: Why is UUR0G331MCL1GS classified as obsolete?

A: Product status reflects manufacturer discontinuation. UWT0G331MCL1GS is the active replacement offering equivalent electrical performance with extended operating temperature capability and assured long-term supply availability.
