Substitute Part Grouping Explanation

Substitution for the UWZ1C470MCL1GS is determined by strict equivalence across the following parameters: capacitance (47 µF), voltage rating (16 V), tolerance (±20%), operating temperature range (-55°C to 105°C), polarization (polar), mounting type (surface mount), and package type (radial can SMD). The land size (0.260" L x 0.260" W) and case diameter (0.248" / 6.30 mm) are critical for PCB compatibility.

Substitute parts are grouped into three categories:

Direct Equivalent (Same Series): UWZ1C470MCL1GB maintains identical electrical specifications and physical dimensions with the original part, differing only in packaging format (Tape & Reel vs. bulk) and product status (Active vs. Obsolete).

Upgrade Equivalent (Enhanced Performance): UWT1C470MCL1GB provides the same core electrical parameters with improved product status (Active) and identical physical footprint, suitable for direct replacement with no design modification required.

Compatible Alternatives (Different Series): UCD1C470MCL1GS, UCD1C470MCL6GS, UCL1C470MCL1GS, UCL1C470MCL6GS, UUA1C470MCL1GS, UUD1C470MCL1GS, UUT1C470MCL1GS, and UWD1C470MCL1GS maintain the core electrical specifications (47 µF, 16 V, ±20%, -55°C to 105°C) but differ in lifetime ratings, ripple current capabilities, impedance characteristics, and physical dimensions. These require verification of mechanical fit and electrical performance margins before implementation.

Engineering Selection Recommendations

For Direct Replacement (No Design Modification):

UWZ1C470MCL1GB is the primary direct equivalent. It maintains identical electrical specifications and physical footprint with the original UWZ1C470MCL1GS. The only differences are product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. Bulk). This part is suitable for immediate substitution in production environments.

UWT1C470MCL1GB provides an upgrade path with Active product status and identical physical dimensions (0.213" height, 6.30 mm diameter, 6.60 mm x 6.60 mm land size). This part is recommended for new designs or production transitions requiring long-term supply assurance.

For Compatible Alternatives (Requires Verification):

Parts with matching case diameter (6.30 mm) and land size (6.60 mm x 6.60 mm) — UCD1C470MCL1GS, UCL1C470MCL1GS, UUA1C470MCL1GS, UUD1C470MCL1GS, UUT1C470MCL1GS, and UWD1C470MCL1GS — are mechanically compatible with the original PCB footprint. These parts offer extended lifetime ratings (2000 to 3000 hours at 105°C) and higher ripple current capabilities. Selection depends on application requirements for thermal performance and current handling.

Parts with reduced case diameter (5.00 mm) and land size (5.30 mm x 5.30 mm) — UCD1C470MCL6GS and UCL1C470MCL6GS — require PCB layout modification and are not suitable for direct substitution without design changes.

Compliance Considerations:

All substitute parts maintain RoHS3 compliance and REACH compliance status consistent with the original part. AEC-Q200 rated parts (UCD1C470MCL1GS, UCD1C470MCL6GS, UUD1C470MCL1GS) are suitable for automotive applications if required.

Frequently Asked Questions (FAQ)

Q: Can UWZ1C470MCL1GB be used as a direct replacement for UWZ1C470MCL1GS?

A: Yes. UWZ1C470MCL1GB is electrically and mechanically equivalent to the original part. Both maintain 47 µF capacitance, 16 V rating, ±20% tolerance, 1000 hour lifetime at 105°C, and identical physical dimensions. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. Bulk).

Q: What is the difference between UWZ1C470MCL1GB and UWT1C470MCL1GB?

A: Both parts are electrically equivalent with identical electrical specifications and physical footprint. UWT1C470MCL1GB belongs to the UWT series and is recommended as an upgrade option due to Active product status and higher inventory availability. The height specification differs slightly (5.40 mm vs. 5.70 mm for UWZ1C470MCL1GB), but both fit the original 6.60 mm x 6.60 mm land pattern.

Q: Can parts with different case diameters (5.00 mm vs. 6.30 mm) be substituted?

A: No. Parts with 5.00 mm case diameter (UCD1C470MCL6GS, UCL1C470MCL6GS) require different PCB land patterns (5.30 mm x 5.30 mm vs. 6.60 mm x 6.60 mm) and cannot be used without PCB redesign. These parts are not suitable for direct substitution.

Q: What are the advantages of higher lifetime-rated parts like UUA1C470MCL1GS (3000 hours)?

A: Higher lifetime ratings indicate extended operational capability at elevated temperatures. UUA1C470MCL1GS provides 3000 hours at 105°C compared to 1000 hours for the original part. This is beneficial for applications requiring extended thermal stress tolerance, though it requires verification that the increased height (6.10 mm vs. 5.40 mm) is compatible with the PCB assembly.

Q: Are automotive-grade parts (AEC-Q200) interchangeable with general-purpose parts?

A: Automotive-grade parts (UCD1C470MCL1GS, UCD1C470MCL6GS, UUD1C470MCL1GS) meet additional qualification standards but are electrically compatible with general-purpose equivalents. Selection depends on application requirements. Automotive-grade parts are required only if the application demands AEC-Q200 compliance.

Q: What packaging formats are available, and do they affect compatibility?

A: Available formats include Bulk, Tape & Reel (TR), and Cut Tape & Digi-Reel (CT). These are supply chain and manufacturing considerations only and do not affect electrical or mechanical compatibility. All formats maintain identical component specifications and PCB footprint requirements.

Q: Can I use parts with higher ripple current ratings as direct substitutes?

A: Yes, if the physical dimensions match. Parts with higher ripple current ratings (e.g., UCL1C470MCL1GS at 150 mA @ 120 Hz vs. 50 mA for the original) are compatible substitutes provided the case diameter (6.30 mm) and land size (6.60 mm x 6.60 mm) match. Higher ripple current capability does not negatively impact performance in applications requiring lower ripple current.
