Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UWS1H151MCL1GS is determined by the following critical parameters:

• Capacitance value: 150 µF (exact match required)
• Voltage rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime rating: 2000 Hrs @ 85°C (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Mounting type: Surface Mount (exact match required)
• Physical dimensions: 0.394" Dia (10.00mm) with compatible height (maximum 0.413")
• Ripple current specifications: 238 mA @ 120 Hz and 309.4 mA @ 10 kHz (exact match required)
• Surface mount land size: 0.406" L x 0.406" W (10.30mm x 10.30mm) (exact match required)

The UUR1H151MNL1GS meets all substitution criteria and is qualified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The UUR1H151MNL1GS is a qualified direct substitute for the UWS1H151MCL1GS. Both parts are manufactured by Nichicon and share identical electrical specifications, including capacitance, voltage rating, tolerance, lifetime rating, and ripple current characteristics. Both components maintain REACH Unaffected status and EAR99 classification.

The primary difference is the seated height: the UUR1H151MNL1GS has a maximum height of 0.413" (10.50mm) compared to 0.394" (10.00mm) for the original part. This 0.019" (0.50mm) height difference must be evaluated against PCB layout constraints and available clearance in the target application.

Both parts carry MSL 1 rating and identical surface mount land sizes, ensuring compatibility with existing PCB designs from a footprint perspective.

Frequently Asked Questions (FAQ)

Q: Can the UUR1H151MNL1GS be used as a direct replacement for the UWS1H151MCL1GS?

A: Yes, the UUR1H151MNL1GS is electrically and mechanically compatible. The electrical specifications are identical. The seated height difference of 0.019" (0.50mm) must be verified against available PCB clearance.

Q: What is the significance of the height difference between these parts?

A: The UUR1H151MNL1GS is 0.019" (0.50mm) taller than the original UWS1H151MCL1GS. In applications with tight vertical clearance constraints, this difference may require PCB layout modification or component repositioning.

Q: Are the surface mount land sizes identical?

A: Yes, both parts use identical surface mount land sizes of 0.406" L x 0.406" W (10.30mm x 10.30mm), ensuring footprint compatibility.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes, both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What are the key electrical parameters that must match for substitution?

A: Capacitance (150 µF), voltage rating (50 V), tolerance (±20%), lifetime rating (2000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), and ripple current specifications (238 mA @ 120 Hz and 309.4 mA @ 10 kHz) must all match exactly.
