Engineering Selection Recommendations

The 860080778021 (Würth Elektronik WCAP-ATLI series) maintains active product status and is the primary selection for new designs. Both Nichicon substitutes (UPJ1J331MHD1TO and UPM1J331MHD1TO) are designated "Not For New Designs," indicating these parts are in mature or end-of-life phases.

The UPM1J331MHD1TO carries AEC-Q200 automotive qualification and is REACH Affected, making it suitable for automotive applications where such certifications are required. The UPJ1J331MHD1TO is REACH Unaffected and carries no specific application rating.

Physical dimensions vary slightly: the Würth part has a 0.512" diameter can versus 0.492" for both Nichicon variants. Height differences are minimal (26.50mm to 27.00mm maximum). These dimensional variations are within typical PCB layout tolerances for radial through-hole components.

Impedance values differ across the three parts (45 mOhms, 72 mOhms, and 49 mOhms respectively), which may affect ripple current performance in high-frequency applications. Selection should account for circuit-specific ripple current requirements.

Frequently Asked Questions (FAQ)

Q: Can UPJ1J331MHD1TO and UPM1J331MHD1TO be used interchangeably with 860080778021?

A: Both Nichicon parts meet the core electrical and mechanical compatibility criteria (capacitance, voltage, tolerance, lifetime, temperature range, lead spacing, and package type). However, the "Not For New Designs" status of both Nichicon parts indicates they are not recommended for new product development. The 860080778021 should be the primary selection for new designs.

Q: What are the key differences between UPJ1J331MHD1TO and UPM1J331MHD1TO?

A: Both parts share identical electrical specifications (330 µF, 63 V, ±20%, 5000 Hrs @ 105°C). The UPM1J331MHD1TO includes AEC-Q200 automotive qualification and is REACH Affected, while the UPJ1J331MHD1TO carries no specific application rating and is REACH Unaffected. Impedance differs slightly (72 mOhms versus 49 mOhms). Maximum seated height varies by 0.020" (0.50mm).

Q: Will the physical dimension differences affect PCB layout?

A: The Würth 860080778021 has a 0.512" diameter can compared to 0.492" for Nichicon parts, a difference of 0.020" (0.50mm). Height variation ranges from 26.50mm to 27.00mm. These differences are within standard PCB layout tolerances for radial through-hole components and should not require layout modifications for typical applications.

Q: Are all three parts RoHS3 compliant?

A: Yes, all three parts are ROHS3 Compliant. The UPM1J331MHD1TO is REACH Affected, while the 860080778021 and UPJ1J331MHD1TO are REACH Unaffected.

Q: How do ripple current ratings compare?

A: The 860080778021 specifies 1.87 A @ 100 kHz. The Nichicon UPJ1J331MHD1TO provides 1.42 A @ 10 kHz and 1.09 A @ 120 Hz. The UPM1J331MHD1TO provides identical ripple current ratings to the UPJ variant. Selection should account for the specific frequency and current requirements of the application circuit.
