Engineering Selection Recommendations

For Direct Replacement (Identical Voltage Rating):

SEK470M016ST is the recommended direct substitute for SH470M016ST. Both parts maintain 16 V voltage rating, identical capacitance (47 µF), tolerance (±20%), and matching ESR specification (5.08 Ohm @ 120Hz). SEK470M016ST holds Active product status, ensuring long-term availability and supply chain continuity. The extended operating temperature range (-55°C to 105°C) provides additional thermal margin. Height difference (0.512" vs. 0.433") requires PCB layout verification for space-constrained applications.

For Voltage-Upgraded Substitution (25 V Rating):

When circuit design permits higher voltage rating, three Active-status alternatives provide enhanced performance:

EEU-EB1E470S (Panasonic Electronic Components) offers the longest operational lifetime (5000 hours @ 105°C) compared to the 2000-hour specification of SH470M016ST. This extended lifetime improves system reliability in continuous-duty applications. Physical dimensions and lead spacing remain compatible. Height is 0.472" (12.00 mm).

EKZE250ELL470ME11D (Chemi-Con) provides the highest ripple current capability at high frequency (250 mA @ 100 kHz) and low frequency (100 mA @ 120 Hz), making it suitable for applications with elevated AC stress. Impedance specification (300 mOhms) indicates superior high-frequency performance. Height is 0.492" (12.50 mm).

UPW1E470MDD (Nichicon) maintains the same height as the original part (0.433" / 11.00 mm), minimizing PCB layout modifications. Extended operating temperature range (-55°C to 105°C) supports wider environmental conditions.

517D476M025JA6AE3 (Vishay Sprague) is classified as Obsolete and should be avoided for new designs requiring long-term component availability.

All substitute parts maintain ROHS3 compliance and identical lead spacing (0.079" / 2.00 mm) and diameter (0.197" / 5.00 mm).

Frequently Asked Questions (FAQ)

Q1: Can I use a 25 V rated capacitor in place of a 16 V rated capacitor?

A: Yes. A higher voltage rating is electrically compatible in applications designed for lower voltage. The 25 V substitute parts (517D476M025JA6AE3, EEU-EB1E470S, EKZE250ELL470ME11D, UPW1E470MDD) will function correctly in circuits rated for 16 V operation. The higher voltage rating provides additional safety margin and does not degrade performance.

Q2: What is the significance of ESR (Equivalent Series Resistance)?

A: ESR affects ripple current handling and heat generation. SH470M016ST specifies 5.08 Ohm @ 120Hz. Lower ESR values improve high-frequency performance and reduce thermal stress. SEK470M016ST maintains identical ESR. Substitute parts with higher voltage ratings do not provide ESR specifications in the available data; however, their ripple current ratings indicate acceptable performance for general-purpose applications.

Q3: Does the height difference between substitute parts affect PCB compatibility?

A: Yes. SH470M016ST height is 0.433" (11.00 mm). SEK470M016ST is 0.512" (13.00 mm), EEU-EB1E470S is 0.472" (12.00 mm), EKZE250ELL470ME11D is 0.492" (12.50 mm), and UPW1E470MDD is 0.433" (11.00 mm). For space-constrained designs, UPW1E470MDD or the original height specification must be verified. PCB clearance above the capacitor must accommodate the taller substitute parts.

Q4: Why is product status (Active vs. Obsolete) important?

A: Active-status parts ensure long-term availability and supply chain reliability. Obsolete parts may become unavailable without notice. For new designs or long-production-run applications, Active-status substitutes (SEK470M016ST, EEU-EB1E470S, EKZE250ELL470ME11D) are preferred. Obsolete substitutes (517D476M025JA6AE3, UPW1E470MDD) are acceptable only for legacy system maintenance with limited production quantities.

Q5: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the environmental and regulatory requirements of SH470M016ST.

Q6: 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 stress. Low-frequency ripple (120 Hz) is typical in power supply applications; high-frequency ripple (10 kHz or 100 kHz) occurs in switching power supplies. SH470M016ST specifies 85 mA @ 120 Hz and 102 mA @ 10 kHz. Substitute parts with higher voltage ratings generally exhibit improved ripple current handling, particularly at high frequencies.

Q7: Can I substitute SH470M016ST with a lower voltage rating capacitor?

A: No. Substituting with a lower voltage rating (e.g., 10 V or 12 V) is not permitted. The capacitor would operate outside its rated voltage specification, creating risk of failure, leakage, or catastrophic breakdown. Voltage rating must equal or exceed the original specification.

Q8: What does ±20% tolerance mean?

A: Tolerance specifies the allowable deviation from the nominal 47 µF capacitance value. ±20% means the actual capacitance may range from 37.6 µF to 56.4 µF. All listed substitute parts maintain identical ±20% tolerance, ensuring compatibility with circuit design margins.
