Substitute Part Grouping Explanation

Substitution eligibility for the UCD1H2R2MCL1GS is determined by the following core parameters: capacitance value (2.2 µF), voltage rating (50 V), tolerance (±20%), package type (Radial, Can - SMD), physical dimensions (0.157" diameter, compatible height), and land size (0.169" x 0.169"). All substitute parts listed maintain these electrical and mechanical specifications.

Secondary parameters including lifetime rating, ripple current specifications, impedance, and application classification may vary between the main part and substitutes. These variations do not prevent functional substitution but may affect performance in specific operating conditions.

Engineering Selection Recommendations

UUT1H2R2MCL1GS: This part is electrically and mechanically equivalent to the UCD1H2R2MCL1GS but carries an Obsolete product status. Selection of this substitute should be limited to applications where existing inventory must be consumed or where legacy design compatibility is required. The part is available in Cut Tape and Digi-Reel packaging, differing from the main part's Tape & Reel format.

UUA1H2R2MCL1GS: This part offers an upgrade path with extended lifetime (3000 hours at 105°C versus 2000 hours). It maintains Active product status and is suitable for applications requiring enhanced reliability. Physical height is reduced to 0.228" (5.80mm), which may provide board layout advantages. This part is recommended for new designs prioritizing extended operational life.

UWG1H2R2MCL1GB: This part maintains Active product status and AEC-Q200 automotive rating equivalent to the main part. However, it features a reduced lifetime specification (1000 hours at 105°C) and lower ripple current capacity. Physical height is further reduced to 0.213" (5.40mm). Selection should be limited to applications with relaxed lifetime requirements or where compact form factor is prioritized.

Frequently Asked Questions (FAQ)

Q: Can UUT1H2R2MCL1GS be used as a direct replacement for UCD1H2R2MCL1GS?

A: Electrically and mechanically, yes. Both parts share identical capacitance (2.2 µF), voltage rating (50 V), tolerance (±20%), and physical dimensions. However, UUT1H2R2MCL1GS is marked Obsolete, making it unsuitable for new production designs. Existing inventory may be used for legacy system support.

Q: What is the primary advantage of UUA1H2R2MCL1GS over the main part?

A: UUA1H2R2MCL1GS provides 50% extended lifetime (3000 hours versus 2000 hours at 105°C) while maintaining all core electrical specifications and Active product status. This makes it suitable for applications requiring enhanced long-term reliability.

Q: Are there height restrictions when substituting with UWG1H2R2MCL1GB?

A: UWG1H2R2MCL1GB has a maximum seated height of 0.213" (5.40mm), compared to 0.240" (6.10mm) for the main part. This reduced height may provide board layout benefits but requires verification that the design does not depend on the original height specification.

Q: Do all substitute parts maintain automotive qualification?

A: UCD1H2R2MCL1GS and UWG1H2R2MCL1GB both carry AEC-Q200 ratings. UUT1H2R2MCL1GS and UUA1H2R2MCL1GS do not list automotive ratings and are classified for General Purpose applications. Automotive designs must verify compliance requirements before substitution.

Q: What packaging formats are available across these parts?

A: UCD1H2R2MCL1GS and UUA1H2R2MCL1GS are supplied in Tape & Reel (TR) format. UUT1H2R2MCL1GS is available in Cut Tape (CT) and Digi-Reel format. UWG1H2R2MCL1GB is supplied in Tape & Reel format. Packaging selection affects handling and assembly processes.
