Engineering Selection Recommendations

For General Purpose Applications (Non-Automotive):

UPW1H331MPD (Nichicon) is the primary substitute within the same manufacturer family. It maintains identical lead spacing and diameter as the UPJ1H331MPD, ensuring direct PCB compatibility. Height reduction from 1.299" to 0.787" may provide design flexibility in space-constrained layouts.

EEU-FC1H331 (Panasonic Electronic Components) is an active product with AEC-Q200 certification. Lead spacing matches the original part (0.197" / 5.00mm), but diameter increases to 0.492" (12.50mm). This part is suitable for applications where automotive-grade reliability is beneficial, even in non-automotive contexts.

For Automotive Applications:

UPM1H331MHD6 (Nichicon) carries AEC-Q200 certification and meets automotive reliability standards. Physical dimensions differ significantly (lead spacing 0.295" / 7.50mm, diameter 0.630" / 16.00mm), requiring PCB layout verification.

EEU-FC1H331B (Panasonic Electronic Components) is an active product with AEC-Q200 certification and Cut Tape packaging. Lead spacing matches the original (0.197" / 5.00mm), but diameter increases to 0.492" (12.50mm). Height is 0.866" (22.00mm).

ELXY500ELL331MJ30S and ELXY500ELL331MK20S (Chemi-Con) both carry AEC-Q200 certification. ELXY500ELL331MJ30S maintains identical lead spacing and diameter as the original part. ELXY500ELL331MK20S offers extended lifetime (7000 Hrs @ 105°C) with different physical dimensions.

ELXZ500ELL331MJ25S (Chemi-Con) is an active product with AEC-Q200 certification, matching lead spacing and diameter of the original part with reduced height (1.043" / 26.50mm).

Product Status Consideration:

The UPJ1H331MPD is marked "Not For New Designs." All recommended substitutes except UPW1H331MPD and UPJ1H331MHD6 are classified as "Active" products, ensuring continued availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can I use EEU-FC1H331 as a direct replacement for UPJ1H331MPD?

A: EEU-FC1H331 meets all electrical specifications (330 µF, 50 V, ±20%, 5000 Hrs @ 105°C) and maintains identical lead spacing (0.197" / 5.00mm). However, the diameter increases from 0.394" to 0.492" (10.00mm to 12.50mm), requiring verification that the PCB layout accommodates the larger component body.

Q: What is the difference between UPJ1H331MPD and UPW1H331MPD?

A: Both parts are manufactured by Nichicon with identical electrical specifications and lead spacing (0.197" / 5.00mm). The primary difference is height: UPJ1H331MPD is 1.299" (33.00mm) tall, while UPW1H331MPD is 0.787" (20.00mm) tall. Both are classified "Not For New Designs."

Q: Are automotive-rated parts (AEC-Q200) suitable for non-automotive applications?

A: Yes. AEC-Q200 certification indicates enhanced reliability testing and stricter manufacturing controls. These parts exceed the requirements of general-purpose applications and provide additional design margin.

Q: What does "Not For New Designs" mean?

A: This designation indicates the part has been superseded in the manufacturer's product line. While existing inventory may be available, the manufacturer does not recommend using these parts in new product development. Active alternatives should be prioritized for new designs.

Q: Can I substitute a part with different lead spacing?

A: No. Lead spacing determines PCB hole positioning and cannot be changed without redesigning the circuit board. Parts with different lead spacing (such as UPJ1H331MHD6 with 0.295" / 7.50mm spacing) require complete PCB layout modification.

Q: What is the significance of impedance and ripple current ratings?

A: These parameters are provided in the source data but are not substitution criteria for this component category. Substitution is determined by capacitance, voltage rating, tolerance, lifetime, operating temperature range, polarization, mounting type, and package type. Impedance and ripple current variations among equivalent parts reflect manufacturing differences but do not affect functional compatibility in standard applications.

Q: Is ELXY500ELL331MK20S a better choice than ELXY500ELL331MJ30S?

A: ELXY500ELL331MK20S offers extended lifetime (7000 Hrs @ 105°C versus 5000 Hrs), providing additional design margin for long-term reliability. However, physical dimensions differ: diameter increases to 0.492" (12.50mm) and height is 0.846" (21.50mm). Selection depends on available PCB space and lifetime requirements.
