Substitute Part Grouping Explanation

Substitution for the 63ST474MB23225 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.47 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 63V DC (exact match required)
• Dielectric material: Acrylic, Metallized (exact match required)
• Package: 1210 (3225 Metric) surface mount (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Termination: Solder pads (exact match required)
• Compliance: ROHS3 and REACH requirements (exact match required)

The 63MU474MB23225 meets all substitution criteria as a direct equivalent, differing only in series designation (MU versus ST) and packaging format (Tape & Reel versus cut tape), with minor dimensional variations within the 1210 package specification.

Parameter Comparison

Engineering Selection Recommendations

The 63MU474MB23225 is the direct substitute for the obsolete 63ST474MB23225. Both parts are manufactured by Rubycon and maintain identical electrical specifications across capacitance, voltage rating, tolerance, and operating temperature range. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH requirements, making them suitable for applications subject to environmental regulations. The primary distinction is packaging format: the substitute is supplied in Tape & Reel configuration versus cut tape, and exhibits minor dimensional variations (width and height) within the 1210 package specification. These dimensional differences remain within standard package tolerances and do not affect PCB footprint compatibility for surface mount assembly.

Frequently Asked Questions (FAQ)

Q: Can the 63MU474MB23225 be used as a direct replacement for the 63ST474MB23225?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 0.47 µF capacitance, ±20% tolerance, 63V DC rating, acrylic metallized dielectric, 1210 package, and -55°C to 125°C operating range. The substitute is actively manufactured and available.

Q: What is the difference between the ST and MU series designations?

A: The series designation indicates internal product line classification within Rubycon's PMLCAP® film capacitor portfolio. Both ST and MU series share identical electrical and mechanical specifications for this part number.

Q: Does the packaging format difference (cut tape versus Tape & Reel) affect compatibility?

A: No. Packaging format affects supply and handling logistics but does not impact electrical performance or PCB assembly compatibility. The component itself is identical; only the delivery format differs.

Q: Are the dimensional variations between the two parts significant?

A: No. The width and height differences (0.063" to 0.098" width; 0.071" to 0.079" height) remain within the 1210 package specification tolerance and do not affect PCB footprint design or assembly processes.

Q: Why is the main part marked as obsolete?

A: Product obsolescence reflects Rubycon's discontinuation of the ST series variant. The MU series equivalent remains in active production, providing a viable path for component replacement and system continuity.
