Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance value: 100 µF (exact match required)
• Voltage rating: Equal to or greater than 250 V
• Tolerance: ±20% (standard tolerance match)
• Polarization: Polar (required for electrolytic type)
• Mounting type: Through Hole (mechanical compatibility)
• Package type: Radial, Can (form factor compatibility)
• Lead spacing: 0.295" (7.50mm) (PCB footprint compatibility)
• Case diameter: 0.709" (18.00mm) (mechanical fit)

Secondary Compatibility Parameters:

• Operating temperature range: Minimum -25°C to 105°C
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The substitute parts listed below satisfy all primary criteria and maintain compatibility with the original SH101M250ST design specifications.

Engineering Selection Recommendations

107CKE400M (Upgrade Option): This part is manufactured by Cornell Dubilier / Illinois Capacitor and maintains active product status. The 107CKE400M provides a voltage rating upgrade to 400 V while preserving the 100 µF capacitance and ±20% tolerance. The increased voltage rating provides additional design margin for applications subject to voltage transients or overvoltage conditions. All mechanical parameters (lead spacing, case diameter, mounting type) are compatible with the original SH101M250ST. The part is ROHS3 compliant and suitable for direct substitution in applications where higher voltage rating is acceptable or beneficial.

UPW2E101MHD (Upgrade Option): Manufactured by Nichicon, this part matches the 250 V voltage rating and 100 µF capacitance of the original SH101M250ST. The UPW2E101MHD offers extended lifetime of 8000 hours at 105°C compared to the original 2000-hour rating, providing improved reliability for long-term operation. Operating temperature range extends to -40°C, offering broader environmental compatibility. All mechanical parameters are compatible. The part is ROHS3 compliant and REACH unaffected. Product status is obsolete.

EEU-EE2E101S (Similar Option): Manufactured by Panasonic Electronic Components, this part is active in production status. The EEU-EE2E101S matches the 250 V voltage rating and 100 µF capacitance. This part offers the highest lifetime rating at 10000 hours at 105°C. The case height is reduced to 1.063" (27.00mm), which may provide space savings in compact designs. All mechanical parameters including lead spacing and case diameter are compatible. The part is ROHS3 compliant and REACH unaffected.

Selection Basis:

• For applications requiring extended component availability: Select EEU-EE2E101S (active status, Panasonic)
• For applications requiring higher voltage margin: Select 107CKE400M (active status, 400 V rating)
• For applications requiring extended operational lifetime: Select EEU-EE2E101S (10000 hours) or UPW2E101MHD (8000 hours)
• For space-constrained designs: Select EEU-EE2E101S (reduced height)

All substitute parts maintain ROHS3 compliance and are compatible with the original through-hole PCB footprint.

Frequently Asked Questions (FAQ)

Q: Can the 107CKE400M replace the SH101M250ST in all applications?

A: The 107CKE400M is electrically compatible as a direct substitute. The 400 V voltage rating exceeds the original 250 V requirement, providing additional design margin. All mechanical parameters (lead spacing, case diameter, mounting type) are identical. The part is suitable for replacement in applications where the original 250 V rating was adequate. The slightly increased height (1.437" vs 1.417") is negligible for most PCB layouts.

Q: What is the difference between the UPW2E101MHD and the original SH101M250ST?

A: Both parts share identical electrical specifications: 100 µF capacitance, 250 V voltage rating, and ±20% tolerance. The primary difference is the extended lifetime: UPW2E101MHD provides 8000 hours at 105°C compared to 2000 hours for the original. The operating temperature range is also extended to -40°C. Mechanical compatibility is maintained. The UPW2E101MHD is suitable for applications requiring improved long-term reliability.

Q: Is the EEU-EE2E101S compatible with the original PCB footprint?

A: Yes. The EEU-EE2E101S maintains identical lead spacing (0.295" / 7.50mm) and case diameter (0.709" / 18.00mm) as the SH101M250ST. The reduced height (1.063" vs 1.417") does not affect footprint compatibility and may provide space savings. The part is a direct mechanical and electrical substitute.

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

A: Equivalent Series Resistance (ESR) varies based on internal construction and manufacturing process. The original SH101M250ST specifies 1.99 Ohm @ 120Hz. The 107CKE400M specifies 3.316 Ohm @ 120Hz. Higher ESR may result in increased heat generation under ripple current conditions. For applications sensitive to ESR, the EEU-EE2E101S or UPW2E101MHD should be selected if ESR specifications are critical.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (107CKE400M, UPW2E101MHD, and EEU-EE2E101S) are ROHS3 compliant, matching the original SH101M250ST compliance status.

Q: Which substitute part has the longest operational lifetime?

A: The EEU-EE2E101S offers the highest lifetime rating at 10000 hours at 105°C. The UPW2E101MHD provides 8000 hours at 105°C. Both exceed the original 2000-hour rating. For applications requiring maximum reliability over extended operation periods, the EEU-EE2E101S is the preferred selection.

Q: Can I use the 107CKE400M in a 250 V circuit?

A: Yes. The 107CKE400M is rated for 400 V operation, which exceeds the 250 V circuit requirement. Operating at a lower voltage than the rated maximum is standard practice and does not degrade component performance. The higher voltage rating provides additional safety margin against transient overvoltages.

Q: What is the difference between "Upgrade" and "Similar" substitute classifications?

A: "Upgrade" substitutes (107CKE400M and UPW2E101MHD) provide enhanced specifications such as higher voltage rating or extended lifetime while maintaining core electrical parameters. "Similar" substitutes (EEU-EE2E101S) match the original specifications closely while offering improvements in specific areas such as active production status or extended lifetime. Both categories are electrically and mechanically compatible.
