Frequently Asked Questions (FAQ)

Q: Can the SH101M100ST be directly replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts maintain the critical electrical parameters (100 µF, 100 V, ±20% tolerance), mechanical dimensions (0.197" lead spacing, through-hole radial can package), and regulatory compliance (ROHS3) required for direct substitution. Physical dimensions vary slightly among manufacturers, but all parts fit standard 5.00mm lead spacing PCB layouts.

Q: What is the difference between the SH101M100ST and SEK101M100ST?

A: Both parts are manufactured by Cornell Dubilier Electronics and share identical electrical specifications and mechanical dimensions. The primary difference is product status: the SH series is obsolete, while the SEK series is in active production. The SEK101M100ST represents the current-production equivalent and is the recommended choice for maintaining manufacturer continuity.

Q: Does the slightly smaller diameter of the 100ZLH100MEFC12.5X16 (0.492" versus 0.512") affect compatibility?

A: No. The critical parameter for PCB compatibility is lead spacing (0.197" or 5.00mm), which is identical across all substitute parts. The can diameter does not affect electrical function or mounting compatibility. The smaller diameter may provide space advantages in compact designs but does not create any compatibility issues.

Q: Why is the EEU-FC2A101 recommended over other options?

A: The EEU-FC2A101 combines three key advantages: active product status ensuring long-term availability, AEC-Q200 automotive qualification providing additional reliability assurance, and a 5000-hour lifetime rating at 105°C that exceeds the original specification. These factors make it the most suitable choice for new designs and applications requiring supply chain stability.

Q: Can the UPW2A101MHD be used in new designs?

A: The UPW2A101MHD is designated "Not For New Designs" by Nichicon, indicating the manufacturer is discontinuing this product line. While the part is currently available and meets all technical specifications, its use should be limited to legacy system maintenance or repair applications where supply continuity is not a primary concern. For new designs, select an active-status alternative such as the EEU-FC2A101 or SEK101M100ST.

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

A: Yes. Ripple current ratings vary among manufacturers and reflect different design approaches. The original SH101M100ST specifies 385 mA at 120 Hz and 539 mA at 10 kHz. Substitute parts provide comparable or enhanced ripple current specifications. For applications with specific ripple current requirements, verify the substitute part's ripple current rating against the circuit design specifications.

Q: What is the significance of the extended operating temperature range (-55°C to 105°C) in some substitutes?

A: Several substitute parts extend the lower operating temperature limit from -40°C to -55°C. This provides broader environmental compatibility for applications operating in cold environments. If the original application operates only within the -40°C to 105°C range, this extended specification provides additional design margin without creating any compatibility issues.

Q: Do all substitute parts have the same ESR (Equivalent Series Resistance)?

A: No. ESR specifications vary among manufacturers and are not provided for all parts in this comparison. The original SH101M100ST specifies 1.33 Ohm at 120 Hz. Substitute parts from different manufacturers may have different ESR values. For applications with specific ESR requirements (such as low-noise power supply filtering), verify the substitute part's ESR specification against circuit design requirements.

Q: Is RoHS3 compliance mandatory for all substitutes?

A: Yes. All substitute parts listed are ROHS3 compliant, meeting current regulatory requirements for electronic components. This compliance is a mandatory criterion for substitution and ensures compatibility with modern manufacturing and environmental standards.
