Engineering Selection Recommendations

For Direct Replacement (Same Electrical Performance):

UPW1E100MDD (Nichicon) is the direct equivalent to SH100M025ST, matching the 25 V voltage rating, 10 µF capacitance, ±20% tolerance, and 2000-hour lifetime at 105°C. Both parts are classified as obsolete; however, UPW1E100MDD maintains higher inventory availability (31,813 units in stock versus 841 units for the original part). This substitute provides identical electrical characteristics with extended operating temperature range (-55°C to 105°C) and improved ripple current handling (54 mA @ 120 Hz versus 39 mA).

For Upgraded Performance and Extended Lifecycle:

EEU-EB1H100S (Panasonic) and EEU-EB1J100S (Panasonic) are active-status products offering 5000-hour lifetime at 105°C, doubling the operational endurance of the original SH100M025ST. Both parts maintain identical mechanical dimensions and lead spacing. EEU-EB1H100S operates at 50 V rating, while EEU-EB1J100S operates at 63 V rating, providing voltage margin for applications originally designed for 25 V operation. These upgrades are suitable for designs requiring extended field life and improved reliability.

For Voltage-Upgraded Applications:

UPW1V100MDD (Nichicon, 35 V), 517D106M050JA6AE3 (Vishay Sprague, 50 V), and ESH106M050AC3AA (KEMET, 50 V) provide higher voltage ratings while maintaining the 10 µF capacitance and ±20% tolerance. These parts are appropriate for circuits where the original 25 V rating provides insufficient margin or where system voltage has been increased. All three maintain through-hole radial can packaging with 0.079" (2.00 mm) lead spacing and 0.197" (5.00 mm) diameter.

Compliance and Certification:

All substitute parts listed are ROHS3 compliant and carry EAR99 ECCN classification, matching the regulatory status of the original SH100M025ST. Panasonic EEU-EB series parts (EEU-EB1H100S and EEU-EB1J100S) include REACH Unaffected designation, providing additional environmental compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can UPW1E100MDD be used as a direct replacement for SH100M025ST?

A: Yes. UPW1E100MDD matches all critical electrical and mechanical parameters: 10 µF capacitance, ±20% tolerance, 25 V voltage rating, 2000-hour lifetime at 105°C, 0.079" (2.00 mm) lead spacing, 0.197" (5.00 mm) diameter, and through-hole radial can package. The substitute provides extended operating temperature range (-55°C to 105°C) and improved ripple current performance.

Q: What is the difference between direct equivalents and upgrade substitutes?

A: Direct equivalents (UPW1E100MDD) maintain identical voltage ratings (25 V) and electrical performance specifications. Upgrade substitutes feature higher voltage ratings (35 V, 50 V, or 63 V) and extended lifetime ratings (5000 hours at 105°C versus 2000 hours), providing design margin and improved reliability for the same capacitance value and tolerance.

Q: Are the Panasonic EEU-EB1H100S and EEU-EB1J100S physically compatible with the original SH100M025ST?

A: Yes, with minor height consideration. Both Panasonic parts maintain identical lead spacing (0.079" / 2.00 mm) and diameter (0.197" / 5.00 mm). The seated height increases from 0.433" (11.00 mm) to 0.472" (12.00 mm), a 0.039" (1.00 mm) increase. This height difference is acceptable for most through-hole PCB layouts but should be verified for space-constrained applications.

Q: Can a 50 V rated capacitor be used in a circuit designed for 25 V?

A: Yes. A 50 V rated capacitor is suitable for 25 V applications. The voltage rating indicates the maximum voltage the capacitor can withstand; operating at lower voltages provides design margin and typically extends component life. Parts such as 517D106M050JA6AE3, EEU-EB1H100S, and ESH106M050AC3AA are all rated for 50 V and are suitable for 25 V circuits.

Q: What is the significance of the 2000-hour versus 5000-hour lifetime rating?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation reaches specified limits. The original SH100M025ST is rated for 2000 hours at 105°C. Panasonic EEU-EB1H100S and EEU-EB1J100S are rated for 5000 hours at 105°C, providing 2.5 times longer operational endurance. For applications requiring extended field life or operating continuously at elevated temperatures, the 5000-hour rated parts are recommended.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (UPW1E100MDD, UPW1V100MDD, 517D106M050JA6AE3, EEU-EB1H100S, EEU-EB1J100S, and ESH106M050AC3AA) are ROHS3 compliant, matching the regulatory status of the original SH100M025ST.

Q: What is the difference between Nichicon UPW1E100MDD and UPW1V100MDD?

A: Both parts are Nichicon UPW series aluminum electrolytic capacitors with 10 µF capacitance and ±20% tolerance. The primary difference is voltage rating: UPW1E100MDD is rated at 25 V (direct equivalent to SH100M025ST), while UPW1V100MDD is rated at 35 V (upgrade substitute). Both maintain identical mechanical dimensions, lead spacing, and 2000-hour lifetime at 105°C. UPW1V100MDD provides higher voltage margin for applications requiring upgraded performance.

Q: Which substitute part offers the best combination of active status and extended lifetime?

A: EEU-EB1H100S and EEU-EB1J100S (Panasonic EB-A series) are both classified as active products with 5000-hour lifetime at 105°C. EEU-EB1H100S operates at 50 V rating, while EEU-EB1J100S operates at 63 V rating. Both parts provide extended field life, current manufacturing availability, and regulatory compliance. Selection between the two depends on required voltage margin for the specific application.
