Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 35ST475MC44532 is determined by strict equivalence across the following parameters:

• Capacitance value: 4.7 µF
• Tolerance: ±20%
• Voltage rating: 35V DC minimum
• Dielectric type: Acrylic, Metallized
• Package: 1812 (4532 Metric)
• Operating temperature range: -55°C ~ 125°C minimum
• Mounting type: Surface Mount
• Compliance: ROHS3 Compliant

The 35MU475MC44532 meets all substitution criteria. Both parts are manufactured by Rubycon, share identical electrical specifications, and are housed in the same physical package with compatible termination methods. The primary distinction is series designation (ST versus MU) and product status (obsolete versus active).

Parameter Comparison

Engineering Selection Recommendations

The 35MU475MC44532 is a direct functional equivalent to the 35ST475MC44532. Both parts satisfy identical electrical and mechanical requirements for DC link and DC filtering applications. The substitute part offers the advantage of active product status, ensuring continued availability and supply chain stability compared to the obsolete main part.

The maximum seated height difference of 0.008" (0.20mm) between the two parts is within typical PCB design tolerances for surface mount components and does not impact circuit functionality or thermal management in standard applications.

Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, confirming compatibility with current manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the 35MU475MC44532 be used as a direct replacement for the 35ST475MC44532?

A: Yes. Both parts share identical capacitance, voltage rating, tolerance, dielectric material, package dimensions, and operating temperature range. The electrical performance and physical footprint are equivalent.

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

A: The ST and MU designations indicate different product series within Rubycon's PMLCAP® film capacitor line. The MU series is currently active, while the ST series is obsolete. Electrical and mechanical specifications remain identical.

Q: Does the height difference affect PCB layout?

A: The seated height difference is 0.008" (0.20mm). This variation is within standard PCB design tolerances for surface mount components and does not require layout modifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 35ST475MC44532 and 35MU475MC44532 are ROHS3 compliant and carry identical moisture sensitivity ratings (MSL 5, 48 hours).

Q: Which part should be selected for new designs?

A: The 35MU475MC44532 should be selected for new designs due to its active product status and assured long-term availability.
