Substitute Part Grouping Explanation

Substitution of the UWD1H330MCL1GS is determined by strict equivalence in the following electrical parameters: capacitance (33 µF), voltage rating (50 V), tolerance (±20%), and polarization (polar). Mechanical compatibility is verified through matching surface mount land size (0.260" L x 0.260" W / 6.60mm x 6.60mm), mounting type (surface mount), and package classification (radial, can - SMD). Physical dimensions including diameter and height may vary within acceptable limits for PCB assembly. Lifetime rating, ripple current specifications, and impedance are secondary parameters that influence performance characteristics but do not prevent substitution when primary electrical and mechanical parameters align. All substitute parts listed maintain ROHS3 compliance and MSL rating 1 status.

Engineering Selection Recommendations

Direct substitution candidates for the UWD1H330MCL1GS are UUD1H330MCL1GS (Nichicon), EEE-FK1H330XP (Panasonic), and 865080645010 (Würth Elektronik). These parts maintain identical electrical specifications (33 µF, 50 V, ±20%, 2000 Hrs @ 105°C) and compatible surface mount land sizes. UUD1H330MCL1GS differs only in packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and height (8.00mm versus 7.70mm), making it suitable for applications where packaging flexibility is acceptable. EEE-FK1H330XP and 865080645010 provide equivalent performance with minor variations in ripple current and impedance within acceptable operating margins.

Parts with reduced lifetime ratings (1000 Hrs @ 105°C) including EMVY500ARA330MF80G and UWG1H330MNL1GS are suitable only for applications where extended thermal endurance is not a design requirement. EEE-FK1H330P and AFK336M50X16T-F present dimensional variations that require PCB layout verification before implementation. EEE-FK1H330P features a larger diameter (0.315" versus 0.248") and different land size (0.327" x 0.327"), while AFK336M50X16T-F has a slightly modified land size width (0.307" versus 0.260").

All listed substitutes maintain ROHS3 compliance and MSL rating 1 status, ensuring compatibility with standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can UUD1H330MCL1GS replace UWD1H330MCL1GS directly on the PCB?

A: Yes. Both parts share identical electrical specifications (33 µF, 50 V, ±20%, 2000 Hrs @ 105°C) and surface mount land size (0.260" x 0.260" / 6.60mm x 6.60mm). The height difference (8.00mm versus 7.70mm) is within typical PCB clearance tolerances for surface mount assembly. Packaging format differs (Cut Tape & Digi-Reel versus Tape & Reel) but does not affect board-level compatibility.

Q: What is the difference between the Nichicon UWD and UUD series?

A: Both series are 33 µF, 50 V aluminum electrolytic capacitors with identical electrical performance and 2000-hour lifetime ratings. The primary distinction is packaging: UWD is supplied in Tape & Reel format, while UUD is supplied in Cut Tape & Digi-Reel format. Series designation reflects internal manufacturing process variations but does not impact functional equivalence.

Q: Are Panasonic EEE-FK1H330XP and EEE-FK1H330P interchangeable with the UWD1H330MCL1GS?

A: EEE-FK1H330XP is directly compatible. It maintains the same electrical specifications and surface mount land size. EEE-FK1H330P is not recommended as a direct replacement due to dimensional differences: it features a larger diameter (0.315" versus 0.248") and different land size (0.327" x 0.327" versus 0.260" x 0.260"), requiring PCB layout modification.

Q: Can parts with 1000-hour lifetime ratings substitute for the 2000-hour rated UWD1H330MCL1GS?

A: Electrical compatibility exists, but thermal endurance differs. EMVY500ARA330MF80G and UWG1H330MNL1GS are rated for 1000 hours at 105°C versus 2000 hours for the UWD1H330MCL1GS. Substitution is acceptable only in applications where extended thermal stress is not anticipated or where operating temperature remains below 105°C.

Q: What are the impedance differences among substitute parts, and do they matter?

A: Impedance values range from 600 mOhms to 710 mOhms across the substitute list. The UWD1H330MCL1GS is specified at 680 mOhms. Minor impedance variations (±30 mOhms) do not significantly impact performance in general purpose applications. For high-frequency ripple current filtering or noise-sensitive circuits, impedance matching to the original specification is recommended.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL rating 1 (unlimited moisture sensitivity level), ensuring compatibility with standard surface mount assembly and storage requirements.

Q: What is the significance of surface mount land size differences?

A: Land size determines PCB pad layout compatibility. The UWD1H330MCL1GS requires 0.260" x 0.260" (6.60mm x 6.60mm) pads. Most direct substitutes (UUD1H330MCL1GS, EEE-FK1H330XP, 865080645010, EMVY500ARA330MF80G) use identical land sizes. EEE-FK1H330P (0.327" x 0.327") and AFK336M50X16T-F (0.260" x 0.307") require PCB modification and are not recommended for direct board-level replacement without design revision.
