Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Capacitance: 2.2 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Operating Temperature Range: -55°C to 105°C (exact match required)
Mounting Type: Surface Mount (exact match required)
Package: Radial, Can - SMD (exact match required)
Physical Diameter: 0.157" (4.00 mm) (exact match required)
Surface Mount Land Size: 0.169" L x 0.169" W (4.30 mm x 4.30 mm) (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Substitute parts may vary in the following non-critical parameters: lifetime at temperature, ripple current specifications, impedance, height (within mechanical constraints), packaging format (Tape & Reel vs. Cut Tape), product status, and application classification. These variations do not affect functional interchangeability in the circuit.

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical requirements for direct substitution with UUD1H2R2MCL1GS. Selection should be based on the following criteria:

For Automotive Applications: UWG1H2R2MCL1GB maintains AEC-Q200 qualification matching the original part. This part is recommended when automotive compliance is mandatory.

For Extended Operational Life: UUA1H2R2MCL1GS and EXV225M050A9BAA both offer 3000 hours lifetime at 105°C, compared to the 2000 hours of the original part. These are suitable for applications requiring enhanced reliability margins.

For Improved Ripple Current Performance: 865060640002 and 865080640002 (Würth Elektronik) provide higher ripple current ratings at both low and high frequencies, with 865060640002 offering the lowest impedance at 2.9 Ohms. These are appropriate for high-current switching applications.

For Active Product Status: UWG1H2R2MCL1GB, UUA1H2R2MCL1GS, 865060640002, 865080640002, and EXV225M050A9BAA are all classified as Active. UUT1H2R2MCL1GS is Obsolete and should be avoided for new designs.

For Packaging Flexibility: All substitute parts are available in Tape & Reel packaging except UUT1H2R2MCL1GS, which uses Cut Tape & Digi-Reel format.

Frequently Asked Questions (FAQ)

Q: Can UUT1H2R2MCL1GS be used as a substitute for UUD1H2R2MCL1GS?

A: UUT1H2R2MCL1GS meets all electrical and mechanical equivalence criteria. However, it is classified as Obsolete product status, making it unsuitable for new designs or long-term supply assurance. Use only in legacy system maintenance where supply is confirmed.

Q: What is the difference between the Nichicon and Würth Elektronik options?

A: Both manufacturers provide electrically equivalent parts with identical capacitance, voltage, and tolerance. Würth Elektronik parts (865060640002 and 865080640002) feature lower impedance and higher ripple current ratings. Nichicon parts maintain automotive qualification (UWG1H2R2MCL1GB) or extended lifetime (UUA1H2R2MCL1GS). Selection depends on application-specific performance requirements.

Q: Does height variation affect PCB layout compatibility?

A: All substitute parts maintain the same 0.157" (4.00 mm) diameter and identical surface mount land size of 0.169" L x 0.169" W (4.30 mm x 4.30 mm). Height variations range from 0.213" to 0.240" (5.40 mm to 6.10 mm). Verify clearance in your specific PCB assembly to confirm mechanical fit, particularly in space-constrained designs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, matching the original UUD1H2R2MCL1GS.

Q: Which substitute offers the best overall performance?

A: EXV225M050A9BAA combines extended 3000-hour lifetime at 105°C with 5 Ohm impedance and high ripple current capability (60 mA @ 100 kHz). This part is recommended for applications requiring maximum reliability and performance headroom.

Q: Can I use UWG1H2R2MCL1GB in automotive applications?

A: Yes. UWG1H2R2MCL1GB carries AEC-Q200 qualification and is classified as Active. It is suitable for automotive applications, though it offers reduced lifetime (1000 hours at 105°C) compared to the original part.
