Engineering Selection Recommendations

For Direct Replacement (Same Electrical Specifications):

UPW0J331MED (Nichicon) is the closest equivalent, maintaining identical electrical specifications and 2000-hour lifetime rating. However, both the main part and this substitute are classified as obsolete. Height is reduced to 0.433" (11.00mm) compared to the original 0.630" (16.00mm), which may require PCB layout verification.

For Active Component Availability:

EEU-FC0J331S and EEU-FC0J331SH (Panasonic) are active products with AEC-Q200 automotive qualification. Both maintain identical capacitance, voltage, tolerance, and lead spacing. Lifetime rating is reduced to 1000 hours at 105°C (versus 2000 hours for the original). Height is 0.441" (11.20mm). These parts are suitable for applications where the reduced lifetime rating is acceptable.

ELXZ6R3ELL331MFB5D (Chemi-Con) is an active product with AEC-Q200 automotive qualification and 2000-hour lifetime rating matching the original specification. Height is 0.512" (13.00mm). This part provides the best balance of active availability and electrical performance.

For Lead Spacing Compatibility:

EEU-FC0J331SB (Panasonic) has a different lead spacing of 0.197" (5.00mm) compared to the standard 0.098" (2.50mm). This part is suitable only if the PCB layout accommodates the wider lead spacing.

For Higher Voltage Applications:

ELXZ100ELL331MF15D (Chemi-Con) provides a 10 V rating with the same 330 µF capacitance and 2000-hour lifetime. This part is suitable as an upgrade option where higher voltage margin is required. Height is 0.650" (16.50mm), matching the original dimension.

Frequently Asked Questions (FAQ)

Q: Can I use EEU-FC0J331S or EEU-FC0J331SH as a direct replacement for UPJ0J331MED?

A: Yes, electrically these parts are compatible. Both maintain 330 µF capacitance, 6.3 V rating, ±20% tolerance, and identical lead spacing. However, the lifetime rating is reduced from 2000 hours to 1000 hours at 105°C. Height is also reduced from 0.630" to 0.441". Verify that your application's thermal and lifetime requirements are satisfied with the reduced rating, and confirm PCB layout accommodates the reduced height.

Q: What is the difference between EEU-FC0J331S and EEU-FC0J331SH?

A: Both parts are electrically identical with the same capacitance, voltage, tolerance, and dimensions. The difference is in packaging: EEU-FC0J331S is supplied in Bulk packaging, while EEU-FC0J331SH is supplied in Cut Tape (CT) packaging. Select based on your procurement and assembly requirements.

Q: Why does EEU-FC0J331SB have different lead spacing?

A: EEU-FC0J331SB has a lead spacing of 0.197" (5.00mm) compared to the standard 0.098" (2.50mm) used in other equivalents. This wider spacing requires different PCB hole positioning. Use this part only if your PCB layout is designed for 5.00mm lead spacing.

Q: Is ELXZ6R3ELL331MFB5D a suitable replacement?

A: Yes. ELXZ6R3ELL331MFB5D maintains all critical electrical parameters: 330 µF, 6.3 V, ±20% tolerance, and standard 0.098" (2.50mm) lead spacing. It is an active product with AEC-Q200 automotive qualification and 2000-hour lifetime rating, matching the original specification. Height is 0.512" (13.00mm), which is intermediate between the original and other active alternatives.

Q: Can I use ELXZ100ELL331MF15D as a replacement?

A: ELXZ100ELL331MF15D is electrically compatible in terms of capacitance and tolerance, but the voltage rating is 10 V instead of 6.3 V. This higher voltage rating provides additional safety margin and is suitable for applications where higher voltage tolerance is beneficial. However, the increased height of 0.650" (16.50mm) matches the original dimension. Confirm that your circuit design accepts the higher voltage rating.

Q: Why are some parts listed as obsolete?

A: UPJ0J331MED and UPW0J331MED are classified as obsolete, indicating they are no longer in active production. Active alternatives from Panasonic and Chemi-Con are recommended for new designs and ongoing production to ensure long-term component availability.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive qualification standard for passive components. Parts bearing this rating have been tested and approved for automotive applications, indicating compliance with automotive reliability and performance standards.
