ALS71A363MF100 Equivalent & Substitute Parts

Part Overview

The ALS71A363MF100 is a 36000 µF, 100 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 values at moderate voltage ratings. The component features a 19000-hour lifetime at 85°C and operates across the temperature range of -40°C to 85°C.

The product maintains Active status and is ROHS3 compliant. Identifying equivalent substitute parts is necessary to ensure supply chain continuity, optimize inventory management, and maintain design flexibility when the primary part becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitution of the ALS71A363MF100 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 36000 µF (exact match required)
• Rated voltage: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 14 mOhm (exact match required)
• Lifetime @ 85°C: 19000 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)
• Lead spacing: 1.122" (28.50 mm) (exact match required)
• Physical dimensions: 2.598" Dia (66.00 mm), 4.213" Height (exact match required)
• Mounting type: Chassis Mount (exact match required)

Compliance Parameters:

• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)

The ALS70A363MF100 qualifies as a parametric equivalent because it maintains identical electrical performance, mechanical compatibility, and regulatory compliance across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71A363MF100 and ALS70A363MF100 are Active products manufactured by KEMET with full ROHS3 compliance and identical electrical and mechanical specifications. The primary distinction between these parts is the series designation (ALS71 versus ALS70), which reflects internal design iterations within KEMET's product line while maintaining complete parametric equivalence.

Selection between these parts should be based on:

1. Availability and Lead Time: Choose the part with the shortest procurement timeline and confirmed stock status.
2. Supply Chain Continuity: If one part becomes unavailable, the alternative provides direct functional replacement without circuit redesign.
3. Regulatory Compliance: Both parts satisfy ROHS3 and REACH requirements for regulated applications.
4. Inventory Optimization: Organizations may standardize on either part number based on existing stock levels and supplier relationships.

No additional testing, qualification, or circuit modification is required when substituting between these parts, as all electrical performance, thermal characteristics, and mechanical interfaces are identical.

Frequently Asked Questions (FAQ)

Q: Can the ALS70A363MF100 be used as a direct replacement for the ALS71A363MF100?

A: Yes. The ALS70A363MF100 is a direct parametric equivalent. All electrical specifications, mechanical dimensions, lead spacing, and compliance certifications are identical. No circuit modifications or additional qualification is required.

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

A: The series designation reflects KEMET's internal product line organization. Both series deliver identical performance for the 36000 µF, 100 V specification. The difference is administrative rather than functional.

Q: Are the physical dimensions and mounting interfaces identical?

A: Yes. Both parts feature identical diameter (2.598" / 66.00 mm), height (4.213" / 107.00 mm), lead spacing (1.122" / 28.50 mm), and screw terminal configuration. They are mechanically interchangeable in chassis-mount applications.

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

A: Yes. Both the ALS71A363MF100 and ALS70A363MF100 support 24.5 A ripple current at 100 Hz and 27.7 A at 10 kHz, with identical ESR of 14 mOhm @ 100Hz.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (unlimited). They are equivalent for regulated applications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -40°C to 85°C with a rated lifetime of 19000 hours at 85°C.

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

A: Yes. The identical electrical performance, mechanical form factor, and lead spacing allow direct substitution without PCB layout changes or circuit redesign.
