Substitute Part Grouping Explanation

Substitute parts for the ALS70P183NF200 are identified based on strict electrical and mechanical parameter matching. 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
• Size / Dimension: 3.031" Dia (77.00mm)
• Height - Seated (Max): 4.213" (107.00mm)
• Lead Spacing: 1.252" (31.80mm)

Compliance & Certification (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The ALS71A183NF200 meets all specified electrical, mechanical, and compliance requirements and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS70P183NF200 and ALS71A183NF200 are active products manufactured by KEMET with identical electrical performance, mechanical dimensions, and compliance certifications. Selection between these parts is based on availability and supply chain requirements:

ALS70P183NF200 (Primary): 1117 units in stock. Use as the first choice when available.

ALS71A183NF200 (Substitute): 896 units in stock. Use when ALS70P183NF200 is unavailable. The ALS71 series represents a design iteration within KEMET's aluminum electrolytic capacitor portfolio while maintaining full electrical and mechanical compatibility.

Both parts satisfy ROHS3 compliance and REACH requirements. No additional testing or verification is required for direct substitution in applications designed for either part number.

Frequently Asked Questions (FAQ)

Q: Can ALS71A183NF200 be used as a direct replacement for ALS70P183NF200?

A: Yes. The ALS71A183NF200 is a parametric equivalent with identical capacitance (18000 µF), voltage rating (200 V), ESR (24 mOhm @ 100Hz), lifetime (20000 Hrs @ 85°C), and mechanical dimensions. Both parts are ROHS3 compliant and REACH unaffected. Direct substitution is supported without circuit modification.

Q: Are there any differences in physical dimensions between these parts?

A: No. Both parts have identical dimensions: 3.031" diameter (77.00mm), 4.213" maximum seated height (107.00mm), and 1.252" lead spacing (31.80mm). Both use radial, can-style screw terminals for chassis mount applications.

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

A: The ALS70 and ALS71 are different series within KEMET's aluminum electrolytic capacitor product line. For the 18000 µF, 200 V specification, both series deliver identical electrical performance and mechanical compatibility. Series designation reflects internal design or manufacturing process differences that do not affect functional equivalence.

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

A: Yes. Both the ALS70P183NF200 and ALS71A183NF200 support 18.8 A ripple current at 100 Hz and 23 A ripple current at 10 kHz, with identical impedance of 19 mOhms.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, have Moisture Sensitivity Level 1 (unlimited), and are REACH unaffected. Compliance status is identical.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supplier lead times. Both parts are active products with equivalent long-term availability.
