Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for aluminum electrolytic capacitors is determined by matching the following critical parameters:

• Electrical Parameters: Capacitance value (27 µF), voltage rating (16 V), and tolerance (±20%) must be identical
• Thermal Specifications: Lifetime rating (2000 Hrs @ 105°C) and operating temperature range (-55°C ~ 105°C) must be equivalent or superior
• Mechanical Compatibility: Package type (Radial, Can - SMD), mounting type (Surface Mount), and surface mount land size (0.209" L x 0.209" W) must match for PCB compatibility
• Environmental Compliance: RoHS3 compliance and MSL rating must be maintained

The UUD1C270MCL1GS meets all substitution criteria as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Both the UWD1C270MCL1GS and UUD1C270MCL1GS are active production parts from Nichicon with identical electrical and thermal specifications. The UUD1C270MCL1GS carries AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability. The UWD1C270MCL1GS is designated for general purpose applications. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level rating. The maximum seated height difference of 0.012" (0.30mm) between the two parts must be evaluated for PCB clearance constraints in the target application. Selection between these parts should be based on application requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can UUD1C270MCL1GS replace UWD1C270MCL1GS in any application?

A: Direct electrical and mechanical substitution is possible due to matching capacitance, voltage rating, tolerance, thermal specifications, and package dimensions. The UUD1C270MCL1GS has a maximum seated height of 0.240" compared to 0.228" for the UWD1C270MCL1GS. PCB clearance must be verified for the specific application.

Q: What are the key differences between these two parts?

A: The primary differences are series designation (UWD versus UUD), application category (general purpose versus automotive), and AEC-Q200 qualification on the UUD variant. Electrical performance, thermal ratings, and surface mount land size are identical.

Q: Are both parts RoHS compliant?

A: Yes, both UWD1C270MCL1GS and UUD1C270MCL1GS are ROHS3 compliant with unlimited moisture sensitivity level rating.

Q: What determines if a part can substitute for the UWD1C270MCL1GS?

A: Substitution requires matching capacitance (27 µF), voltage rating (16 V), tolerance (±20%), thermal lifetime (2000 Hrs @ 105°C), operating temperature range (-55°C ~ 105°C), package type (Radial, Can - SMD), and surface mount land size (0.209" L x 0.209" W).

Q: Is the height difference between these parts significant?

A: The UUD1C270MCL1GS has a maximum seated height of 0.240" versus 0.228" for the UWD1C270MCL1GS, a difference of 0.012" (0.30mm). This must be evaluated against PCB component clearance requirements and assembly constraints.
