Substitute Part Grouping Explanation

Substitution of the 63ST474M3225 is based on strict equivalence across the following parameters:

• Capacitance value: 0.47 µF (exact match required)
• Tolerance: ±20% (identical tolerance band)
• Voltage rating: 63V DC (minimum requirement)
• Dielectric type: Acrylic, Metallized (same material composition)
• Package: 1210 (3225 Metric) (identical footprint and dimensions)
• Operating temperature range: -55°C ~ 125°C (same thermal specification)
• Mounting type: Surface Mount (same assembly method)
• Compliance: ROHS3 Compliant, REACH Unaffected (regulatory alignment)

The 63MU474MB23225 meets all these criteria and is classified as a parametric equivalent. The primary distinction is product status: the original part is obsolete while the substitute remains active in production.

Parameter Comparison

Engineering Selection Recommendations

The 63MU474MB23225 is a direct parametric equivalent to the 63ST474M3225 across all electrical and mechanical specifications. Both parts are manufactured by Rubycon and maintain identical performance characteristics for DC link and DC filtering applications.

The primary advantage of selecting the 63MU474MB23225 is its active product status. As the original part is obsolete, the substitute ensures long-term component availability and supply chain continuity. Both parts carry equivalent regulatory compliance (ROHS3 Compliant, REACH Unaffected) and identical moisture sensitivity ratings.

The 63MU474MB23225 is supplied in Tape & Reel (TR) packaging, which is standard for high-volume production environments. This packaging format is compatible with automated assembly processes and does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 63MU474MB23225 be used as a direct replacement for the 63ST474M3225?

A: Yes. Both parts are identical in capacitance (0.47 µF), voltage rating (63V DC), tolerance (±20%), dielectric material (acrylic metallized), package dimensions (1210 / 3225 metric), and operating temperature range (-55°C ~ 125°C). They are electrically and mechanically interchangeable.

Q: What is the difference between these two parts?

A: The 63MU474MB23225 differs from the 63ST474M3225 in two aspects: product status (active versus obsolete) and packaging format (Tape & Reel versus standard). These differences do not affect electrical performance or physical compatibility.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 4, 72 hours). Regulatory and environmental certifications are equivalent.

Q: Is the Tape & Reel packaging compatible with my assembly process?

A: Tape & Reel packaging is the standard format for automated surface mount assembly. If your process uses manual placement or non-standard equipment, confirm compatibility with your assembly provider. The physical dimensions and solder pad configuration remain unchanged.

Q: What is the inventory status of these parts?

A: The 63ST474M3225 has 820 pieces in stock (obsolete status). The 63MU474MB23225 has 2794 pieces in stock and is actively produced, providing superior long-term availability.
