Parameter Comparison

Engineering Selection Recommendations

Both the ALS70A183NF200 and ALS71A183NF200 are active products manufactured by KEMET with full compliance to ROHS3 and REACH requirements. The parts are electrically and mechanically identical across all specified parameters. Selection between these parts is based on availability and supply chain considerations rather than technical performance differences.

The ALS70A183NF200 is the primary part number with higher current inventory (976 units). The ALS71A183NF200 serves as a direct substitute with equivalent performance characteristics and 896 units in stock. Both parts are suitable for general-purpose applications requiring 18000 µF capacitance at 200 V with screw terminal connections for chassis mounting.

Frequently Asked Questions (FAQ)

Q: Can ALS71A183NF200 be used as a direct replacement for ALS70A183NF200?

A: Yes. The ALS71A183NF200 is a parametric equivalent with identical electrical specifications (18000 µF, 200 V, 24 mOhm ESR @ 100Hz, 20000 Hrs @ 85°C), identical mechanical dimensions (3.031" diameter, 4.213" height, 1.252" lead spacing), and identical package type (Radial, Can - Screw Terminals). Both parts are ROHS3 compliant and REACH unaffected.

Q: Are there any differences in performance between ALS70A183NF200 and ALS71A183NF200?

A: No. Both parts have identical ripple current ratings (18.8 A @ 100 Hz, 23 A @ 10 kHz), identical impedance (19 mOhms), identical operating temperature range (-40°C ~ 85°C), and identical tolerance (±20%).

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

A: The series designation reflects different product lines within KEMET's aluminum electrolytic capacitor portfolio. Both series share identical electrical and mechanical specifications for this 18000 µF, 200 V rating. The difference is in the product line classification only.

Q: Are the screw terminals compatible between both parts?

A: Yes. Both ALS70A183NF200 and ALS71A183NF200 use identical radial, can-style screw terminal connections with 1.252" (31.80mm) lead spacing, suitable for direct PCB or chassis mounting applications.

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

A: Both parts are rated for 18.8 A ripple current at 100 Hz and 23 A ripple current at 10 kHz. Application suitability depends on the specific ripple current profile of the target circuit.

Q: What is the moisture sensitivity level for these parts?

A: Both ALS70A183NF200 and ALS71A183NF200 have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
