Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 16ST475MC14532 is determined by strict alignment of the following critical parameters:

• Capacitance value: 4.7 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 16V DC minimum (exact match required)
• Dielectric material: Acrylic, Metallized (exact match required)
• Package format: 1812 (4532 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Termination type: Solder Pads (exact match required)

The substitute part 16MU475MC14532 meets all substitution criteria. Both components are manufactured by Rubycon, belong to the PMLCAP® film capacitor family, maintain identical electrical specifications, and are housed in the same 1812 (4532 Metric) surface mount package. The primary distinction lies in the series designation (ST versus MU) and minor physical height variation, which does not affect functional compatibility in standard PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

Both the 16ST475MC14532 and 16MU475MC14532 are Active products with full regulatory compliance certifications. Selection between these components should be based on availability and inventory requirements rather than technical performance differences, as both parts deliver identical electrical performance in DC link and DC filtering applications.

The 16MU475MC14532 substitute part carries higher inventory availability (1564 pcs versus 762 pcs for the main part), making it a viable alternative when supply constraints affect the primary component. The maximum seated height difference of 0.008" (0.20mm) between the two parts falls within standard PCB design tolerances and does not necessitate layout modifications for typical surface mount applications.

Both components maintain RoHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental and regulatory requirements for manufacturing and end-use applications.

Frequently Asked Questions (FAQ)

Q: Can the 16MU475MC14532 be used as a direct replacement for the 16ST475MC14532 in existing designs?

A: Yes. Both parts share identical electrical specifications (4.7 µF, ±20%, 16V DC), dielectric material composition, operating temperature range, and package dimensions. The series designation change (ST to MU) reflects internal Rubycon product line organization and does not affect functional compatibility.

Q: What is the significance of the height difference between these two parts?

A: The main part has a maximum seated height of 0.055" (1.40mm), while the substitute has 0.063" (1.60mm). This 0.008" (0.20mm) difference is within standard PCB design clearance tolerances and does not require circuit board layout modifications for standard surface mount applications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance status, REACH unaffected designation, and Moisture Sensitivity Level (MSL) rating of 5 (48 Hours). Regulatory and environmental compliance requirements are equivalent.

Q: What applications are these capacitors suitable for?

A: Both the 16ST475MC14532 and 16MU475MC14532 are specified for DC link and DC filtering applications, where their 4.7 µF capacitance and 16V DC rating provide stable energy storage and voltage stabilization in power distribution circuits.

Q: How do I determine if a substitute part is acceptable for my specific application?

A: Verify that your circuit design requires a 4.7 µF capacitor with ±20% tolerance rated for 16V DC operation in a 1812 (4532 Metric) surface mount package. If these parameters match your design specifications, either part is functionally equivalent.
