Parameter Comparison

Engineering Selection Recommendations

The 100MU473MA23216 is a direct substitute for the obsolete 100ST473MA23216. Both parts are manufactured by Rubycon and maintain identical electrical characteristics: 0.047 µF capacitance, ±20% tolerance, and 100V DC rating with acrylic metallized dielectric. Both are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for current production environments.

The substitute part offers an extended operating temperature range (-55°C to 125°C versus -55°C to 105°C) and is classified as active product status, ensuring continued availability and supply chain stability. The maximum seated height difference of 0.008" (0.20mm) is within typical PCB design tolerances for 1206 surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can 100MU473MA23216 be used as a direct replacement for 100ST473MA23216?

A: Yes. Both parts share identical capacitance (0.047 µF), tolerance (±20%), voltage rating (100V DC), dielectric material (acrylic metallized), package (1206), and termination (solder pads). The substitute maintains all electrical and mechanical compatibility for DC link and DC filtering applications.

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

A: The main part has a maximum seated height of 0.055" (1.40mm), while the substitute measures 0.063" (1.60mm). This 0.008" (0.20mm) difference is within standard PCB design clearances for 1206 surface mount components and does not affect circuit board layout compatibility.

Q: Why is the operating temperature range different?

A: The substitute part (100MU473MA23216) supports -55°C to 125°C operation, compared to -55°C to 105°C for the main part. This extended upper temperature limit provides additional thermal margin for applications operating at elevated ambient or component temperatures.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both 100ST473MA23216 and 100MU473MA23216 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations for electronic components.

Q: What packaging options are available for the substitute part?

A: The 100MU473MA23216 is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. Verify packaging requirements for your specific procurement and assembly workflow.
