Engineering Selection Recommendations

Direct Equivalents (Preferred for Replacement):

The SEK470M025ST (Mallory) provides the closest electrical match to the SH470M025ST with identical ESR and ripple current specifications. This part is currently active and ROHS3 compliant. The extended operating temperature range (-55°C to 105°C) provides additional margin. Height variation (0.512" vs. 0.433") must be verified against PCB layout constraints.

Active Status Alternatives:

The EEU-FM1E470 and EEU-FR1E470 (Panasonic) are active products with enhanced ripple current handling (196 mA @ 120 Hz, 280 mA @ 100 kHz). The EEU-FR1E470 offers extended lifetime (5000 hours @ 105°C) compared to the original 2000-hour specification. Both parts accommodate the same lead spacing and voltage rating. Height is 0.492" (12.50 mm), requiring PCB verification.

The EKZE250ELL470ME11D (Chemi-Con) is an active alternative with moderate ripple current capability (100 mA @ 120 Hz) and 2000-hour lifetime. This part maintains the same operating temperature range as the original.

The EEU-EB1E470S (Panasonic) is an active upgrade option with 5000-hour lifetime at 105°C and ROHS3 compliance. Ripple current is lower (55 mA @ 120 Hz), suitable for applications with reduced ripple requirements.

Obsolete Status Parts:

The UPW1E470MDD (Nichicon) and 517D476M025JA6AE3 (Vishay Sprague) are obsolete but remain in stock. These parts are electrically compatible but should be considered only when active alternatives are unavailable or when existing inventory must be utilized.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the SH470M025ST with any of the listed parts?

A: All listed parts meet the mandatory equivalence parameters: 47 µF capacitance, 25 V rating, ±20% tolerance, polar configuration, 0.079" lead spacing, through-hole mounting, and radial can package. Physical height variations must be verified against PCB layout. Active status parts (SEK470M025ST, EEU-FM1E470, EEU-FR1E470, EKZE250ELL470ME11D, EEU-EB1E470S) are preferred for new designs.

Q: What is the difference between the Panasonic EEU-FM1E470 and EEU-FR1E470?

A: Both parts are identical in electrical specifications and physical dimensions. The primary difference is lifetime rating: EEU-FM1E470 is rated for 2000 hours at 105°C, while EEU-FR1E470 is rated for 5000 hours at 105°C. The EEU-FR1E470 is suitable for applications requiring extended operational life.

Q: Does the height difference between substitute parts affect PCB compatibility?

A: Yes. The original SH470M025ST has a maximum seated height of 0.433" (11.00 mm). Substitute parts vary: SEK470M025ST is 0.512" (13.00 mm), EEU-FM1E470 and EEU-FR1E470 are 0.492" (12.50 mm), EKZE250ELL470ME11D is 0.492" (12.50 mm), UPW1E470MDD is 0.433" (11.00 mm), and EEU-EB1E470S is 0.472" (12.00 mm). PCB clearance and component placement must be verified before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the significance of ESR in capacitor selection?

A: Equivalent Series Resistance (ESR) affects capacitor performance in ripple current applications and thermal stability. The original SH470M025ST specifies 4.52 Ohm @ 120 Hz. The SEK470M025ST matches this specification exactly. Other substitutes do not specify ESR but provide higher ripple current ratings, which may compensate for ESR variations in specific applications.

Q: Which substitute part offers the best long-term reliability?

A: The EEU-FR1E470 and EEU-EB1E470S (Panasonic) both offer 5000-hour lifetime at 105°C, compared to the original 2000-hour specification. These parts provide extended operational life for critical applications. Both are active products with full ROHS3 compliance.

Q: Can I use the UPW1E470MDD or 517D476M025JA6AE3 in new designs?

A: Both parts are electrically compatible but classified as obsolete. They should not be used in new designs. These parts are suitable only for maintenance and repair of existing equipment or when active alternatives are unavailable and existing inventory must be utilized.

Q: What is the difference between ripple current at 120 Hz and 10 kHz?

A: Ripple current specifications at different frequencies indicate the capacitor's ability to handle AC current superimposed on DC voltage. The original SH470M025ST handles 90 mA @ 120 Hz and 108 mA @ 10 kHz. Higher ripple current capability at higher frequencies indicates better performance in switching power supply applications. Substitute parts with higher ripple current ratings provide additional design margin.
