SK470M016ST (Cornell Dubilier Electronics) is the primary direct equivalent. This part maintains identical capacitance, voltage rating, and tolerance specifications. The SK series offers improved performance with 2000-hour lifetime at 85°C compared to the original 1000-hour rating, and lower ESR (4.52 Ohm). Lead spacing differs at 0.079" (2.00 mm) versus 0.098" (2.50 mm), requiring PCB layout verification. Case diameter is smaller (0.197" vs. 0.248"), providing better board space utilization. Height is significantly greater (0.512" vs. 0.276"), requiring clearance validation. Product status is Active with full availability.

ECE-A1CKS470 (Panasonic Electronic Components, KS Series) provides direct electrical equivalence with 47 µF, 16 V, ±20% tolerance. Lead spacing and case diameter match the original part exactly (0.098" and 0.248" respectively). Height is reduced to 0.236", improving board clearance. Lifetime specification matches at 1000 hours @ 85°C. Product status is Active. REACH compliance is confirmed.

Voltage Upgrade Option:

ECE-A1EKA470 (Panasonic Electronic Components, KA Series) provides a 25 V rated variant of the same 47 µF capacitor. This upgrade is suitable for applications requiring higher voltage margin or operating in circuits with voltage transients.

Frequently Asked Questions (FAQ)

Q: Can SK470M016ST be used as a direct replacement for SS470M016ST?

A: SK470M016ST is electrically equivalent with identical capacitance (47 µF), voltage rating (16 V), and tolerance (±20%). However, lead spacing differs (0.079" vs. 0.098"), and height is significantly greater (0.512" vs. 0.276"). PCB layout modification is required. The SK series offers superior performance with 2000-hour lifetime and lower ESR.

Q: What is the difference between ECE-A1CKS470 and ECE-A1EKA470?

A: Both are Panasonic 47 µF capacitors with identical physical dimensions and lead spacing. ECE-A1CKS470 is rated at 16 V, while ECE-A1EKA470 is rated at 25 V. The 25 V variant (ECE-A1EKA470) provides higher voltage margin for circuits with transient conditions or design safety requirements. Both have 1000-hour lifetime @ 85°C.

Q: Are all substitute parts through-hole mounted?

A: Yes. All listed substitutes are through-hole mounted radial can capacitors, maintaining compatibility with existing PCB designs that accommodate through-hole components.

Q: Which substitute offers the best thermal performance?

A: ESH476M035AE3AA (KEMET) provides the best thermal performance with 2000-hour lifetime @ 105°C and operating range to 105°C. EEA-GA1C470 (Panasonic) also offers extended temperature capability with 1000-hour lifetime @ 105°C and -55°C lower temperature limit.

Q: Do all substitutes meet RoHS compliance?

A: Yes. All listed substitute parts are ROHS3 compliant, meeting environmental and regulatory requirements equivalent to the original SS470M016ST.

Q: What is the impact of different ESR values on circuit performance?

A: Lower ESR values reduce heat generation and improve high-frequency performance. SK470M016ST (4.52 Ohm) has lower ESR than the original SS470M016ST (4.8 Ohm), providing marginal improvement. ECE-A1CKS470, ECE-A1EKA470, EEA-GA1C470, and ESH476M035AE3AA do not specify ESR values in available data.

Q: Can ESH476M035AE3AA be used in a 16 V circuit?

A: Yes. ESH476M035AE3AA is rated at 35 V, which exceeds the 16 V requirement. Higher voltage-rated capacitors operate safely in lower-voltage circuits. However, the significantly greater height (0.492" vs. 0.276") requires board clearance verification.

Q: What is the lead spacing significance for PCB design?

A: Lead spacing determines hole-to-hole distance on the PCB. SS470M016ST uses 0.098" (2.50 mm) spacing. SK470M016ST uses 0.079" (2.00 mm), requiring PCB modification. All other substitutes use 0.098" (2.50 mm), maintaining direct PCB compatibility.

Q: Are there inventory considerations for substitute selection?

A: Yes. SK470M016ST has 4,317 pcs available; ECE-A1CKS470 has 906 pcs; ECE-A1EKA470 has 13,190 pcs; EEA-GA1C470 has 8,362 pcs; ESH476M035AE3AA has 17,403 pcs. Higher inventory availability may influence long-term supply chain decisions.
