Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SS470M6R3ST is determined by the following critical parameters:

Core Compatibility Parameters:

• Capacitance: 47 µF (required, fixed)
• Tolerance: ±20% (required, fixed)
• Package Type: Radial, Can (required, fixed)
• Mounting Type: Through Hole (required, fixed)
• Lead Spacing: 0.079" (2.00mm) (required, fixed)
• Physical Diameter: 0.197" Dia (5.00mm) (required, fixed)

Voltage and Thermal Flexibility:

• Rated voltage may exceed 6.3 V (upgrades acceptable; downgrades not acceptable)
• Operating temperature may exceed -40°C ~ 85°C (upgrades acceptable; downgrades not acceptable)
• Lifetime at temperature may exceed 1000 Hrs @ 85°C (upgrades acceptable; downgrades not acceptable)

Compliance:

• ROHS3 compliance maintained across all substitutes

Substitute parts are grouped into three categories based on voltage rating: direct equivalents at 6.3 V, voltage upgrades at 10 V and 16 V, and higher-voltage alternatives at 25 V. All maintain identical capacitance, tolerance, lead spacing, and physical diameter, ensuring mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Voltage Equivalent (6.3 V): ECE-A0JKS470 (Panasonic, KS Series) provides pin-for-pin and electrical equivalence to the obsolete SS470M6R3ST. This part is currently in active production with 894 pieces in inventory. Both parts share identical voltage rating, capacitance, tolerance, physical dimensions, and temperature operating range. Selection of this part requires no circuit redesign or board layout modification.

Voltage Upgrade Options (10 V and 16 V): ECE-A1AKA470 and ECE-A1CKA470 (Panasonic, KA Series) are rated at 10 V and 16 V respectively, exceeding the original 6.3 V specification. Both parts maintain identical package geometry, lead spacing, and physical footprint. These parts are suitable for applications where higher voltage margin is acceptable or required. The 10 V option (4,848 units in inventory) and 16 V option (10,741 units in inventory) provide design flexibility with extended voltage headroom.

Higher-Voltage Alternative (25 V): ESH476M025AC3AA (KEMET, ESH Series) operates at 25 V with an extended operating temperature range of -40°C ~ 105°C and enhanced thermal lifetime rating of 2000 hours at 105°C. This part maintains identical physical footprint and lead spacing but provides superior thermal performance. Selection of this part is appropriate for applications requiring enhanced thermal stability or higher voltage safety margin.

All substitute parts maintain ROHS3 compliance and are currently in active production status, ensuring supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can ECE-A0JKS470 be used as a direct replacement for SS470M6R3ST? A: Yes. ECE-A0JKS470 matches all critical parameters including voltage rating (6.3 V), capacitance (47 µF), tolerance (±20%), lead spacing (0.079"), physical diameter (0.197"), and mounting type (through hole radial, can). No circuit modifications are required.

Q: What is the difference between the voltage-upgraded substitutes (ECE-A1AKA470 and ECE-A1CKA470)? A: ECE-A1AKA470 is rated at 10 V, while ECE-A1CKA470 is rated at 16 V. Both maintain identical capacitance, tolerance, package geometry, and lead spacing. The voltage difference allows selection based on circuit operating conditions and desired safety margin. Height dimensions differ: ECE-A1AKA470 is 0.276" and ECE-A1CKA470 is also 0.276".

Q: Are there physical footprint differences among the substitute parts? A: All substitute parts maintain the same lead spacing (0.079" / 2.00mm) and barrel diameter (0.197" / 5.00mm). Height variations exist: SS470M6R3ST is 0.276", ECE-A0JKS470 is 0.197", ECE-A1AKA470 is 0.276", ECE-A1CKA470 is 0.276", and ESH476M025AC3AA is 0.492". Verify board clearance for taller variants.

Q: Should ESH476M025AC3AA be selected over direct equivalents? A: ESH476M025AC3AA is appropriate when extended operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C) or enhanced thermal lifetime (2000 hours at 105°C versus 1000 hours at 85°C) is required by application specifications. For standard operating conditions, direct equivalents are preferred for cost efficiency.

Q: Are all substitutes ROHS3 compliant? A: Yes. All substitute parts (ECE-A0JKS470, ECE-A1AKA470, ECE-A1CKA470, and ESH476M025AC3AA) are ROHS3 compliant, matching the compliance status of the original part.

Q: What inventory availability exists for these substitutes? A: ECE-A0JKS470 has 894 units available. ECE-A1AKA470 has 4,848 units available. ECE-A1CKA470 has 10,741 units available. ESH476M025AC3AA has 5,979 units available. All parts are in active production.
