Substitute Part Grouping Explanation

Substitution eligibility for the UPM1C331MPD6TD is determined by the following criteria:

Direct Electrical Compatibility: Capacitance value (330 µF) and tolerance (±20%) must remain constant. Voltage rating may be equal or higher; a higher voltage rating provides additional design margin and is acceptable for direct substitution.

Physical Compatibility: Lead spacing (5.00 mm), case diameter (10.00 mm), and mounting type (Through Hole, Radial) must match to ensure PCB footprint compatibility without layout modifications.

Environmental Specifications: Operating temperature range (-55°C to 105°C) and lifetime rating (5000 hours minimum @ 105°C) establish baseline reliability requirements.

Compliance & Status: RoHS3 compliance is maintained across all substitute options. Product status transitions from Not For New Designs to Active indicate improved availability and ongoing manufacturer support.

Engineering Selection Recommendations

Direct Equivalent (Same Voltage Rating): The UPJ1C331MPD6TD maintains identical electrical specifications (330 µF, 16 V, ±20%) and physical dimensions as the UPM1C331MPD6TD. This part is suitable for direct replacement in existing designs where voltage margin is not a constraint. Both parts carry Not For New Designs status, indicating limited future availability.

Upgraded Alternatives (Higher Voltage Rating): The UPW1E331MPD1TD, 860080475013, and 860160475020 all feature 25 V ratings, providing 56% additional voltage margin over the original 16 V specification. These parts are electrically and physically compatible with the UPM1C331MPD6TD footprint. The Würth Elektronik options (860080475013 and 860160475020) carry Active product status, ensuring ongoing availability and manufacturer support.

Extended Lifetime Option: The 860160475020 (Würth Elektronik WCAP-ATLL series) provides 7000 hours lifetime at 105°C, compared to 5000 hours for the original part, offering improved long-term reliability in thermal stress environments.

Compliance Assurance: All substitute parts maintain RoHS3 compliance and are suitable for applications requiring automotive or general-purpose reliability standards.

Frequently Asked Questions (FAQ)

Q: Can UPJ1C331MPD6TD be used as a direct replacement for UPM1C331MPD6TD?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (16 V), tolerance (±20%), lead spacing (5.00 mm), case diameter (10.00 mm), and operating temperature range (-55°C to 105°C). Physical footprint compatibility is confirmed. Both parts are classified as Not For New Designs.

Q: What is the advantage of using a 25 V rated part instead of the original 16 V?

A: A 25 V rated capacitor provides additional voltage margin in the circuit, reducing stress on the dielectric and extending component life. The UPW1E331MPD1TD, 860080475013, and 860160475020 all offer this upgrade while maintaining identical capacitance, tolerance, physical dimensions, and lead spacing.

Q: Are the Würth Elektronik parts (860080475013 and 860160475020) compatible with the original PCB layout?

A: Yes. Both Würth Elektronik parts maintain the same lead spacing (5.00 mm), case diameter (10.00 mm), and Through Hole mounting configuration as the UPM1C331MPD6TD. No PCB modifications are required.

Q: What is the difference between 860080475013 and 860160475020?

A: Both are Würth Elektronik 330 µF, 25 V radial capacitors with identical physical dimensions. The 860160475020 (WCAP-ATLL series) provides 7000 hours lifetime at 105°C compared to 5000 hours for the 860080475013 (WCAP-ATLI series), offering extended reliability for high-temperature applications.

Q: Why do some substitute parts have different impedance values?

A: Impedance variation reflects differences in internal construction and materials between manufacturers and series. The UPW1E331MPD1TD (90 mOhms) and 860080475013 (54 mOhms) offer lower impedance than the original UPM1C331MPD6TD (120 mOhms), which may provide performance benefits in ripple current applications. Impedance differences do not affect basic substitution compatibility for standard filtering applications.

Q: Which substitute part offers the best long-term availability?

A: The 860080475013 and 860160475020 (both Würth Elektronik) carry Active product status, indicating ongoing manufacturer support and availability. The Nichicon alternatives (UPJ1C331MPD6TD and UPW1E331MPD1TD) are classified as Not For New Designs, suggesting limited future availability.
