Voltage Rating: 10 V minimum (equal or higher voltage ratings are acceptable)
Polarization: Polar (required)
Mounting Type: Through Hole (required)
Package Type: Radial, Can (required)
Lead Spacing: 0.098" (2.50 mm) (exact match required)
Case Diameter: 0.248" (6.30 mm) (exact match required)
Height: 0.276" (7.00 mm) maximum (equal or lower height acceptable)

Secondary Compatibility Parameters:

Operating Temperature Range: -40°C minimum to 85°C maximum (equal or wider range acceptable)

Engineering Selection Recommendations

Direct Equivalent (Same Manufacturer):

SK470M010ST (Cornell Dubilier Electronics) is a direct equivalent from the same manufacturer. This part maintains identical electrical specifications (47 µF, ±20%, 10 V) and mechanical dimensions (0.098" lead spacing, 0.248" diameter, 0.276" height). The SK470M010ST offers improved reliability with 2000 hours lifetime at 85°C compared to the original 1000 hours, while maintaining ROHS3 compliance and active product status. This part is recommended as the primary replacement for direct substitution.

Direct Manufacturer Equivalent (Alternative Manufacturer):

ECE-A1AKS470 (Panasonic Electronic Components) provides direct electrical and mechanical equivalence with identical capacitance (47 µF), tolerance (±20%), voltage rating (10 V), and physical dimensions. This part is active and ROHS3 compliant. The ECE-A1AKS470 offers higher ripple current capability at high frequencies (110.5 mA @ 100 kHz) compared to the original specification, supporting applications with increased AC stress.

Voltage Upgrade Options:

ECE-A1EKA470 (Panasonic, 25 V rating) and EEA-GA1C470 (Panasonic, 16 V rating) provide higher voltage ratings while maintaining the same 47 µF capacitance and ±20% tolerance. These upgrades are suitable for applications requiring voltage margin or operating in circuits with potential voltage transients. Both parts are active and ROHS3 compliant.

Extended Temperature Range Options:

EEA-GA1A470 (Panasonic, 10 V, -55°C to 105°C) and EEA-GA1C470 (Panasonic, 16 V, -55°C to 105°C) extend the operating temperature range beyond the original -40°C to 85°C specification. These parts support applications in extreme thermal environments and offer 1000 hours lifetime at 105°C. Both are active and ROHS3 compliant.

High-Reliability Option:

ESH476M035AE3AA (KEMET, 35 V rating) provides the highest voltage rating and extended lifetime (2000 hours @ 105°C) with the widest operating temperature range (-40°C to 105°C). This part is suitable for demanding applications requiring maximum reliability and thermal performance. The part is active and ROHS3 compliant.

Not Recommended:

SK470M010ST exhibits mechanical incompatibility due to reduced case diameter (0.197" vs. 0.248") and significantly increased height (0.512" vs. 0.276"), making it unsuitable for space-constrained applications despite electrical equivalence.

ESH476M035AE3AA exhibits mechanical incompatibility due to increased height (0.492" vs. 0.276"), making it unsuitable for applications with strict height constraints despite superior electrical performance.

Frequently Asked Questions (FAQ)

Q: Can SK470M010ST be used as a direct replacement for SS470M010ST?

A: SK470M010ST is electrically equivalent but exhibits mechanical incompatibility. The case diameter is reduced (0.197" vs. 0.248") and height is significantly increased (0.512" vs. 0.276"). This part is suitable only if the PCB layout and mechanical envelope accommodate the larger height dimension.

Q: What is the primary advantage of ECE-A1AKS470 over the original SS470M010ST?

A: ECE-A1AKS470 maintains identical electrical and mechanical specifications while offering improved ripple current handling at high frequencies (110.5 mA @ 100 kHz vs. 64.9 mA @ 1 kHz). This part is manufactured by Panasonic and carries active product status with ROHS3 compliance.

Q: When should I select a voltage upgrade such as ECE-A1EKA470 (25 V) instead of an equivalent-voltage part?

A: Voltage upgrades are selected when the application circuit operates near the rated voltage limit, experiences voltage transients, or requires design margin for reliability. A 25 V rated capacitor in a 10 V circuit provides additional safety margin without changing the physical footprint or capacitance value.

Q: Are the extended temperature range parts (EEA-GA1A470, EEA-GA1C470) compatible with the original circuit design?

A: Yes. Extended temperature range parts maintain identical capacitance (47 µF), tolerance (±20%), and physical dimensions. They are direct mechanical and electrical substitutes with enhanced performance in extreme temperature environments. Operating temperature range expansion does not affect compatibility in standard temperature applications.

Q: What is the significance of the 2000-hour lifetime specification in SK470M010ST and ESH476M035AE3AA?

A: The 2000-hour lifetime at rated temperature indicates extended operational reliability compared to the original 1000-hour specification. This parameter reflects the capacitor's ability to maintain performance over extended service periods. Selection depends on application duty cycle and required service life.

Q: Can ESH476M035AE3AA be used in a space-constrained application?

A: ESH476M035AE3AA is not suitable for applications with strict height constraints. The part height (0.492") exceeds the original specification (0.276") by 0.216 inches. Mechanical verification is required before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (SK470M010ST, ECE-A1AKS470, ECE-A1EKA470, EEA-GA1A470, EEA-GA1C470, ESH476M035AE3AA) are ROHS3 compliant, meeting environmental and regulatory requirements equivalent to the original SS470M010ST.

Q: What is the difference between lead spacing specifications (0.098" vs. 0.079")?

A: Lead spacing determines the distance between component leads on the PCB. SK470M010ST uses 0.079" (2.00 mm) spacing, which differs from the original 0.098" (2.50 mm) specification. This difference requires PCB layout modification and is not a direct mechanical substitute.

Q: Which substitute part offers the best overall performance?

A: ESH476M035AE3AA offers the highest voltage rating (35 V), extended lifetime (2000 hours @ 105°C), and widest operating temperature range (-40°C to 105°C). However, mechanical incompatibility (increased height) may restrict its use. For applications with standard mechanical constraints, ECE-A1AKS470 provides optimal balance of electrical performance and mechanical compatibility.
