ALS70G183NF200 Equivalent & Substitute Parts

Part Overview

The ALS70G183NF200 is an 18000 µF, 200 V aluminum electrolytic capacitor manufactured by KEMET in the ALS70 series. This radial, can-style capacitor with screw terminals is designed for general-purpose applications requiring high capacitance and voltage ratings. The part is currently Active in product status with 992 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or design flexibility within the same performance envelope.

Substitute Part Grouping Explanation

Substitute parts for the ALS70G183NF200 are identified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Capacitance: 18000 µF
• Voltage Rating: 200 V
• Tolerance: ±20%
• ESR @ 100Hz: 24 mOhm
• Lifetime @ 85°C: 20000 Hrs
• Operating Temperature Range: -40°C ~ 85°C
• Ripple Current @ 100 Hz: 18.8 A
• Ripple Current @ 10 kHz: 23 A

Mechanical Parameters (Must Match):

• Package / Case: Radial, Can - Screw Terminals
• Mounting Type: Chassis Mount
• Lead Spacing: 1.252" (31.80mm)
• Size / Dimension: 3.031" Dia (77.00mm)
• Height - Seated (Max): 4.213" (107.00mm)

Compliance & Status (Must Match):

• RoHS Status: ROHS3 Compliant
• Product Status: Active
• Polarization: Polar

The ALS71A183NF200 meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS70G183NF200 and ALS71A183NF200 are Active products manufactured by KEMET with full ROHS3 compliance. Selection between these parts is based on availability and supply chain requirements, as all electrical and mechanical parameters are identical. The primary difference is the series designation (ALS70 versus ALS71), which reflects internal KEMET product line organization but does not affect functional performance or compatibility.

For applications requiring the 18000 µF, 200 V specification with screw terminal mounting, either part number is suitable for direct substitution. Inventory availability should be the determining factor: ALS70G183NF200 has 992 units in stock, while ALS71A183NF200 has 896 units in stock.

Frequently Asked Questions (FAQ)

Q: Can ALS71A183NF200 be used as a direct replacement for ALS70G183NF200?

A: Yes. All electrical parameters, mechanical dimensions, mounting specifications, and compliance certifications are identical. Direct substitution is supported without circuit modification.

Q: What is the difference between the ALS70 and ALS71 series?

A: The series designation reflects KEMET's internal product line organization. No functional or performance differences exist between these series for this capacitance and voltage rating.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical lead spacing (1.252" / 31.80mm), diameter (3.031" / 77.00mm), and maximum seated height (4.213" / 107.00mm). PCB layout and mounting hardware compatibility are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ALS70G183NF200 and ALS71A183NF200 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes.

Q: What is the ripple current rating for these capacitors?

A: Ripple current is 18.8 A at 100 Hz and 23 A at 10 kHz for both parts.

Q: Can these capacitors be used in high-temperature applications?

A: Both parts are rated for operation from -40°C to 85°C with a lifetime of 20000 hours at 85°C. Applications requiring operation above 85°C require alternative component selection.
