Performance Parameters (Acceptable if Equal or Superior):

• ESR: 880 mOhm @ 120Hz or lower

Substitute parts are grouped into two categories: direct equivalents (matching voltage rating) and upgrades (higher voltage rating with identical or superior performance metrics).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Voltage Rating):

SEK331M010ST (Cornell Dubilier Electronics) is the primary direct equivalent. This part maintains identical electrical specifications (330 µF, 10 V, ±20%, 880 mOhm ESR, 2000 Hrs @ 105°C) while offering an extended operating temperature range (-55°C to 105°C versus -40°C to 105°C). The SEK series is in active production status, ensuring supply chain continuity. This part is recommended for direct replacement in existing designs without modification.

EEU-FC1A331 (Panasonic Electronic Components) is an alternative direct equivalent with identical voltage and capacitance ratings. This part features superior ripple current handling (360.8 mA @ 120 Hz and 555 mA @ 100 kHz) and carries AEC-Q200 automotive qualification. It is suitable for applications requiring enhanced performance margins.

UPW1A331MPD (Nichicon) matches the voltage and capacitance specifications with extended lifetime (3000 Hrs @ 105°C) and superior ripple current performance (360.75 mA @ 120 Hz). However, this part is classified as "Not For New Designs," limiting its use to legacy system maintenance.

Voltage Upgrade Options (Higher Voltage Rating):

EEU-FC1C331 (Panasonic Electronic Components) provides a 16 V rated upgrade with identical 330 µF capacitance. This part is suitable for applications where voltage margin improvement is beneficial. It maintains the same physical footprint and lead spacing, with superior ripple current specifications and AEC-Q200 qualification.

UPW1C331MPD (Nichicon) offers 16 V rating with 330 µF capacitance and 3000 Hrs lifetime. This part is classified as "Not For New Designs."

UHE1C331MPD (Nichicon) provides 16 V rating with extended 7000 Hrs lifetime at 105°C. This part is classified as "Not For New Designs" and carries REACH Affected status.

Compliance Status:

All substitute parts are ROHS3 compliant. Panasonic parts (EEU-FC series) carry REACH Unaffected status. Nichicon parts (UPW and UHE series) carry REACH Unaffected or REACH Affected status as indicated.

Frequently Asked Questions (FAQ)

Q: Can SEK331M010ST be used as a direct replacement for SH331M010ST?

A: Yes. SEK331M010ST is a direct equivalent with identical electrical specifications (330 µF, 10 V, ±20% tolerance, 880 mOhm ESR, 2000 Hrs @ 105°C). The SEK series is in active production, making it the recommended replacement for obsolete SH series components. The extended operating temperature range (-55°C to 105°C) provides additional design margin.

Q: What is the difference between 10 V and 16 V rated parts?

A: The voltage rating indicates the maximum continuous voltage the capacitor can withstand. A 16 V rated part (EEU-FC1C331, UPW1C331MPD, UHE1C331MPD) can be used in applications designed for 10 V operation, providing additional voltage margin and safety factor. However, 16 V parts typically have different internal construction and may have different ESR or ripple current characteristics. Physical dimensions remain identical for the specified parts.

Q: Are there differences in ripple current handling between substitute parts?

A: Yes. The original SH331M010ST specifies 255 mA @ 120 Hz and 306 mA @ 10 kHz. Panasonic EEU-FC series parts provide 360.8 mA @ 120 Hz and 555 mA @ 100 kHz, representing superior ripple current performance. Nichicon UPW series parts provide 360.75 mA @ 120 Hz. These differences reflect different internal construction and may be relevant for high-ripple-current applications.

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

A: Parts marked "Not For New Designs" (UHE1C331MPD, UPW1A331MPD, UPW1C331MPD) are in limited or declining production. While they remain available for legacy system support and maintenance, they should not be selected for new product development. For new designs, use active status parts: SEK331M010ST or EEU-FC series.

Q: Do all substitute parts have the same physical dimensions?

A: Yes. All substitute parts specified maintain identical lead spacing (0.138" / 3.50mm), diameter (0.315" / 8.00mm), and maximum seated height (0.453" / 11.50mm). They are mechanically interchangeable in through-hole PCB applications.

Q: What is the significance of ESR (Equivalent Series Resistance)?

A: ESR affects capacitor performance in high-frequency applications and ripple current handling. The original SH331M010ST specifies 880 mOhm @ 120 Hz. Lower ESR values indicate better high-frequency performance. Panasonic EEU-FC parts specify 117 mOhms impedance, and Nichicon UPW parts specify 117 mOhms impedance, both representing significant improvements over the original specification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. Panasonic EEU-FC series parts are REACH Unaffected. Nichicon UPW series parts are REACH Unaffected. Nichicon UHE1C331MPD is REACH Affected. Verify REACH compliance requirements for your specific application and region.

Q: What is the difference between Panasonic EEU-FC1A331 and EEU-FC1C331?

A: EEU-FC1A331 is rated for 10 V, while EEU-FC1C331 is rated for 16 V. Both have identical 330 µF capacitance, physical dimensions, and ripple current specifications. The 16 V version (EEU-FC1C331) provides higher voltage margin for applications where additional safety factor is required.

Q: Can I use a higher voltage rated capacitor in place of a lower voltage rated one?

A: Yes. A 16 V rated capacitor can be used in a 10 V application. The higher voltage rating provides additional design margin and safety factor. However, verify that the physical dimensions and lead spacing remain compatible with your PCB layout, and confirm that any performance differences (such as ESR or ripple current) are acceptable for your application.

Q: What is the lifetime specification and why does it vary?

A: Lifetime at temperature (e.g., 2000 Hrs @ 105°C) indicates the expected operational life under specified conditions. The original SH331M010ST specifies 2000 Hrs. Substitute parts vary: SEK331M010ST (2000 Hrs), EEU-FC series (2000 Hrs), UPW series (3000 Hrs), and UHE1C331MPD (7000 Hrs). Longer lifetime indicates improved reliability and extended operational capability under thermal stress.
