Substitute Part Grouping Explanation

Substitution for the UHD1E331MPD1TD is determined by strict equivalence across the following critical parameters:

Electrical Equivalence: Capacitance (330 µF), voltage rating (25 V), and tolerance (±20%) must be identical
Physical Compatibility: Lead spacing (0.138" / 4.60 mm), case diameter (0.315" / 8.00 mm), and height (0.650" / 16.50 mm) must match for PCB footprint compatibility
Mechanical Configuration: Package type (Radial, Can) and mounting type (Through Hole) must be identical
Environmental Compliance: RoHS3 compliance is required for regulatory alignment

The substitute parts listed below meet all these criteria. Variations in impedance, ripple current ratings, operating temperature range, and product status are noted but do not prevent functional substitution when the core parameters align.

Engineering Selection Recommendations

UPW1E331MPD6TA (Nichicon): This part maintains manufacturer continuity within Nichicon's product line and shares identical electrical and physical specifications with the UHD1E331MPD1TD. However, it carries the same Not For New Designs status. Selection of this part is appropriate for direct replacement in existing designs or legacy system support where Nichicon component consistency is required.

EKZE250ETD331MH15D (Chemi-Con): This part is Active in production status, providing long-term supply assurance. It matches all critical electrical and physical parameters and maintains identical impedance (56 mOhms) and ripple current ratings at both 120 Hz and 100 kHz. This part is suitable for new designs or redesigns requiring current production components.

ELXZ250EC3331MH15D and ELXZ250ETC331MH15D (Chemi-Con): Both parts are Active in production and carry AEC-Q200 automotive qualification. These are appropriate for applications requiring automotive-grade reliability. They feature extended operating temperature range (-55°C to 105°C) compared to the original part. Impedance and ripple current ratings differ slightly but remain within acceptable substitution parameters. Packaging is Tape & Reel (TR) rather than Cut Tape (CT).

For new designs, EKZE250ETD331MH15D or the automotive-qualified ELXZ250 series are recommended due to Active product status and assured supply continuity.

Frequently Asked Questions (FAQ)

Q: Can UPW1E331MPD6TA be used as a direct replacement for UHD1E331MPD1TD?

A: Yes. Both parts are manufactured by Nichicon and share identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), physical dimensions, lead spacing, and package configuration. Electrical performance is equivalent for general purpose applications.

Q: What is the difference between the Nichicon and Chemi-Con substitute parts?

A: All substitute parts meet the core electrical and physical compatibility requirements. Nichicon parts (UPW1E331MPD6TA) maintain manufacturer consistency. Chemi-Con parts (EKZE250ETD331MH15D, ELXZ250 series) offer Active production status. The ELXZ250 series additionally provides AEC-Q200 automotive qualification and extended temperature range (-55°C to 105°C).

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

A: Impedance variation reflects differences in internal construction between manufacturers and series. The UHD1E331MPD1TD and EKZE250ETD331MH15D both specify 56 mOhms, while ELXZ250 series parts specify 90 mOhms. These differences do not prevent functional substitution when capacitance, voltage, and physical parameters match.

Q: Are the Chemi-Con ELXZ250 parts suitable for general purpose applications?

A: Yes. Although rated for automotive applications with AEC-Q200 qualification, these parts are fully compatible with general purpose circuits. The automotive qualification indicates higher reliability standards and extended temperature capability, making them suitable for any application requiring the specified electrical and physical characteristics.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging is supplied in individual strips, suitable for lower-volume or manual assembly. Tape & Reel packaging is supplied on continuous reels for automated assembly equipment. Both packaging types contain identical components; the difference is in handling and assembly method only.

Q: Should I select an Active product status part for new designs?

A: Yes. Parts with Active status (EKZE250ETD331MH15D, ELXZ250EC3331MH15D, ELXZ250ETC331MH15D) are in current production and offer assured long-term supply. Parts marked Not For New Designs (UHD1E331MPD1TD, UPW1E331MPD6TA) are appropriate only for legacy system maintenance or existing design support.
