Substitute Part Grouping Explanation

Substitution eligibility for the UWD1H2R2MCL1GS is determined by the following critical parameters:

• Capacitance value: 2.2 µF (exact match required)
• Voltage rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Physical dimensions: 0.157" Dia, 0.240" height, 0.169" x 0.169" land size (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Mounting type: Surface Mount (exact match required)

Acceptable variations include:

• Lifetime rating at 105°C (may differ)
• Packaging format (Tape & Reel vs. Cut Tape)
• Series designation (UWD, UWG, UUT)
• Product status (Active or Obsolete)
• Ripple current specifications (may vary within acceptable limits)

Parameter Comparison

Engineering Selection Recommendations

UWG1H2R2MCL1GB is a direct substitute for applications where packaging format flexibility is acceptable. This part maintains identical electrical specifications and physical footprint compatibility. The reduced lifetime rating of 1000 hours at 105°C versus 2000 hours should be evaluated against application duty cycle requirements. This part carries AEC-Q200 automotive qualification and is currently in Active product status.

UUT1H2R2MCL1GS provides parametric equivalence with matching 2000-hour lifetime at 105°C. This part is classified as Obsolete and is available only through existing inventory channels. The reduced ripple current specifications (11 mA @ 120 Hz and 16.5 mA @ 10 kHz) require evaluation for applications with high ripple current demands. Packaging is provided in Cut Tape and Digi-Reel format rather than standard Tape & Reel.

Frequently Asked Questions (FAQ)

Q: Can UWG1H2R2MCL1GB be used as a direct replacement for UWD1H2R2MCL1GS?

A: Yes, UWG1H2R2MCL1GB is electrically and mechanically compatible. The primary difference is the reduced lifetime rating of 1000 hours at 105°C compared to 2000 hours. Applications operating continuously at elevated temperatures should evaluate this specification against design requirements.

Q: What is the height difference between UWG1H2R2MCL1GB and UWD1H2R2MCL1GS?

A: UWG1H2R2MCL1GB has a seated height of 0.213" (5.40mm) versus 0.240" (6.10mm) for UWD1H2R2MCL1GS. Both parts share identical land size and diameter, ensuring PCB footprint compatibility. The reduced height may provide board layout advantages in space-constrained designs.

Q: Is UUT1H2R2MCL1GS still available for new designs?

A: UUT1H2R2MCL1GS is classified as Obsolete. While inventory exists, this part should not be selected for new designs. UWD1H2R2MCL1GS or UWG1H2R2MCL1GB are recommended for ongoing production.

Q: What are the ripple current differences between these parts?

A: UWD1H2R2MCL1GS and UWG1H2R2MCL1GB both support 15 mA at 120 Hz and 30 mA at 100 kHz. UUT1H2R2MCL1GS supports lower ripple currents of 11 mA at 120 Hz and 16.5 mA at 10 kHz. Applications with high ripple current requirements should use UWD1H2R2MCL1GS or UWG1H2R2MCL1GB.

Q: Are all three parts RoHS3 compliant?

A: Yes, all three parts are ROHS3 Compliant with MSL Rating 1 (Unlimited moisture sensitivity level).
