Parameter Comparison

Engineering Selection Recommendations

Both the ALS70H183NF200 and ALS71A183NF200 are active production parts from KEMET with full compliance to ROHS3 and REACH regulations. Selection between these parts is based on inventory availability and supply chain considerations rather than technical performance differences.

The ALS70H183NF200 has 813 units in current stock. The ALS71A183NF200 has 896 units in current stock. Both parts carry identical electrical specifications, mechanical dimensions, and environmental ratings. Component selection should prioritize availability and lead time requirements for the application.

Both parts are suitable for general-purpose applications requiring 18000 µF capacitance at 200 V with screw terminal connections for chassis-mounted installations.

Frequently Asked Questions (FAQ)

Q: Can ALS71A183NF200 be used as a direct replacement for ALS70H183NF200?

A: Yes. The ALS71A183NF200 is a parametric equivalent with identical electrical performance, mechanical dimensions, and environmental compliance. Both parts meet the same 18000 µF, 200 V specification with 24 mOhm ESR and 20000-hour lifetime at 85°C.

Q: Are there physical dimension differences between these parts?

A: No. Both parts have identical physical dimensions: 3.031" diameter (77.00mm), 4.213" maximum seated height (107.00mm), and 1.252" lead spacing (31.80mm). Both use screw terminal connections and are designed for chassis mounting.

Q: Do both parts have the same ripple current ratings?

A: Yes. Both the ALS70H183NF200 and ALS71A183NF200 support 18.8 A ripple current at 100 Hz and 23 A ripple current at 10 kHz.

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

A: The series designation reflects internal KEMET product line organization. Both series share identical electrical and mechanical specifications for this 18000 µF, 200 V rating. Selection is based on availability.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both ALS70H183NF200 and ALS71A183NF200 are ROHS3 compliant and REACH unaffected. Both carry Moisture Sensitivity Level 1 (unlimited shelf life).

Q: What is the operating temperature range for these capacitors?

A: Both parts operate across -40°C to 85°C. The rated lifetime of 20000 hours applies at the 85°C upper temperature limit.

Q: Can these capacitors be used interchangeably in existing designs?

A: Yes. The identical electrical parameters, mechanical form factor, and screw terminal interface allow direct substitution in circuit designs and PCB layouts without modification.
