ALS71G183NF200 Equivalent & Substitute Parts

Part Overview

The ALS71G183NF200 is an 18000 µF, 200 V aluminum electrolytic capacitor manufactured by KEMET in the ALS71 series. This radial, can-style capacitor with screw terminals is designed for general-purpose applications requiring high capacitance and voltage ratings. The part maintains an active product status with 20000 hours lifetime at 85°C operating temperature. Substitute parts are identified when equivalent electrical and mechanical parameters are required for component procurement, inventory management, or design flexibility while maintaining circuit performance specifications.

Substitute Part Grouping Explanation

Substitution of the ALS71G183NF200 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 18000 µF (exact match required)
• Rated voltage: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 24 mOhm (exact match required)
• Lifetime @ 85°C: 20000 Hrs (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Ripple current specifications @ 100 Hz and 10 kHz (exact match required)

Mechanical Parameters:

• Package type: Radial, Can - Screw Terminals (exact match required)
• Mounting type: Chassis Mount (exact match required)
• Physical dimensions: 3.031" Dia (77.00mm), Height 4.213" (107.00mm) (exact match required)
• Lead spacing: 1.252" (31.80mm) (exact match required)

Compliance & Status:

• Product status: Active
• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part ALS71A183NF200 meets all these criteria and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both ALS71G183NF200 and ALS71A183NF200 are active products manufactured by KEMET with identical electrical and mechanical specifications. Selection between these parts is based on availability and inventory status rather than technical performance differences.

ALS71G183NF200: 1163 pieces in stock. Primary selection when immediate availability is required.

ALS71A183NF200: 896 pieces in stock. Alternative selection when primary part is unavailable.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), suitable for general-purpose applications. The identical ESR, ripple current ratings, and lifetime specifications ensure equivalent circuit performance in all applications where the ALS71G183NF200 is specified.

Frequently Asked Questions (FAQ)

Q: Can ALS71A183NF200 be used as a direct replacement for ALS71G183NF200?

A: Yes. The ALS71A183NF200 is a parametric equivalent with identical electrical and mechanical specifications, including capacitance (18000 µF), voltage rating (200 V), ESR (24 mOhm @ 100Hz), ripple current ratings, physical dimensions, and screw terminal configuration. Direct substitution is supported without circuit modification.

Q: What is the difference between the ALS71G and ALS71A base part numbers?

A: The base part number designation (G versus A) does not reflect differences in the provided electrical or mechanical parameters. Both variants are part of the ALS71 series and share identical specifications for capacitance, voltage, ESR, lifetime, temperature range, and physical dimensions.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical dimensions: 3.031" diameter (77.00mm), maximum seated height of 4.213" (107.00mm), and lead spacing of 1.252" (31.80mm). Chassis mount installation requirements are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ALS71G183NF200 and ALS71A183NF200 are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) and REACH unaffected status.
