Substitute Part Grouping Explanation
Substitution eligibility for the UPM1V331MHD6TO is determined by strict equivalence across the following critical parameters:
- Capacitance value: 330 µF (exact match required)
- Voltage rating: 35 V (exact match required)
- Tolerance: ±20% (exact match required)
- Polarization: Polar (exact match required)
- Lead spacing: 0.197" (5.00 mm) (exact match required)
- Package type: Radial, Can (exact match required)
- Mounting type: Through Hole (exact match required)
- RoHS compliance: ROHS3 Compliant (minimum requirement)
The UPJ1V331MHD6TO meets all substitution criteria. Both parts share identical electrical specifications (capacitance, voltage, tolerance, temperature range) and mechanical compatibility (lead spacing, package configuration, mounting method). Variations in impedance, ripple current handling, and application classification do not preclude substitution when electrical and mechanical parameters align.

Engineering Selection Recommendations
Both the UPM1V331MHD6TO and UPJ1V331MHD6TO are ROHS3 compliant and manufactured by Nichicon. The UPM1V331MHD6TO carries AEC-Q200 automotive certification, while the UPJ1V331MHD6TO is classified for general-purpose applications. Selection between these parts depends on application requirements:
For automotive applications requiring AEC-Q200 certification, the UPM1V331MHD6TO remains the specified choice. The UPJ1V331MHD6TO serves as a functional equivalent for general-purpose applications where automotive qualification is not mandated. The 0.019" (0.50 mm) difference in seated height and 35 mOhms impedance variance are within acceptable tolerances for through-hole PCB mounting and do not affect electrical performance in standard filtering and energy storage applications.
Frequently Asked Questions (FAQ)
Q: Can UPJ1V331MHD6TO replace UPM1V331MHD6TO in automotive circuits?
A: Electrical and mechanical compatibility is confirmed. However, the UPJ1V331MHD6TO lacks AEC-Q200 certification. Use in automotive applications requires design review to determine whether AEC-Q200 qualification is a mandatory requirement for your specific application.
Q: Are there physical mounting differences between these parts?
A: Both parts use identical lead spacing (0.197" / 5.00 mm) and radial, can package configuration. The UPJ1V331MHD6TO has a maximum seated height of 0.650" (16.50 mm) compared to 0.669" (17.00 mm) for the UPM1V331MHD6TO. This 0.019" difference is negligible for standard through-hole PCB layouts.
Q: Do impedance differences affect circuit performance?
A: The UPM1V331MHD6TO has 65 mOhms impedance while the UPJ1V331MHD6TO has 100 mOhms. Both values are acceptable for filtering and energy storage applications. High-frequency ripple current handling remains equivalent at 1.02 A @ 10 kHz for both parts.
Q: What is the significance of "Not For New Designs" status?
A: This designation indicates the UPM1V331MHD6TO is in legacy production. New designs should evaluate current-generation alternatives. However, existing designs and production runs may continue using this part or its functional equivalent, the UPJ1V331MHD6TO.
Q: Are both parts RoHS compliant?
A: Yes, both UPM1V331MHD6TO and UPJ1V331MHD6TO are ROHS3 compliant and suitable for applications requiring RoHS certification.
