Substitute Part Grouping Explanation

Substitution for the 25ST475M4532 is based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Capacitance value: 4.7 µF (exact match required)
• Tolerance: ±20% (identical specification)
• Voltage rating: 25V DC (minimum requirement)
• Dielectric material: Acrylic, Metallized (same composition)
• Package: 1812 (4532 Metric) (identical footprint and dimensions)
• Operating temperature range: -55°C ~ 125°C (full range compatibility)
• Mounting type: Surface Mount (same assembly method)
• Termination: Solder Pads (same connection method)

The substitute part 25MU475MC24532 meets all these parameters identically. The primary difference is the series designation (MU versus ST) and product status (Active versus Obsolete), with no impact on electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 25MU475MC24532 be used as a direct replacement for the 25ST475M4532?

A: Yes. Both parts share identical electrical specifications (4.7 µF, ±20%, 25V DC), dielectric material (Acrylic, Metallized), package dimensions (1812/4532 Metric), and operating temperature range (-55°C ~ 125°C). The parts are mechanically and electrically interchangeable.

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® family. Both ST and MU series share identical performance parameters for this capacitance and voltage rating. The designation does not affect functional compatibility.

Q: Why is the original part marked as Obsolete?

A: Obsolete status indicates the 25ST475M4532 is no longer in active production. The 25MU475MC24532 (Active status) represents the current production equivalent, ensuring long-term supply availability.

Q: Are there packaging differences between these parts?

A: The main part is supplied in standard packaging, while the substitute (25MU475MC24532) is available in Tape & Reel (TR) format. Both use identical solder pad termination and fit the same 1812 (4532 Metric) footprint.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 25ST475M4532 and 25MU475MC24532 are ROHS3 compliant, REACH unaffected, and carry identical Moisture Sensitivity Level (MSL) ratings of 5 (48 Hours).
