Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ALS71H184KF025 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Capacitance: 180000 µF
• Voltage Rating: 25 V
• Tolerance: ±20%
• ESR @ 100Hz: 13 mOhm

Mechanical Parameters (Must Match):

• Package / Case: Radial, Can - Screw Terminals
• Mounting Type: Chassis Mount
• Size / Dimension: 2.008" Dia (51.00mm)
• Height - Seated (Max): 4.213" (107.00mm)
• Lead Spacing: 0.874" (22.20mm)

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Polarization: Polar

The ALS80A184KF025 meets all substitution criteria. While operating temperature range and lifetime specifications differ between the main part and substitute, these parameters do not disqualify substitution when the core electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both ALS71H184KF025 and ALS80A184KF025 are Active product status components manufactured by KEMET with ROHS3 compliance and REACH unaffected status. Selection between these parts is based on application-specific requirements:

Select ALS71H184KF025 when:

• Application operates within -40°C to 85°C temperature range
• Extended operational lifetime at 85°C (18000 hours) is required
• Higher ripple current handling at 100 Hz (20.3 A) and 10 kHz (21.4 A) is necessary

Select ALS80A184KF025 when:

• Application requires extended temperature operation up to 105°C
• Component availability or inventory status favors this part number
• Ripple current specifications of 17.6 A @ 100 Hz and 18.7 A @ 10 kHz are acceptable

Both parts maintain identical electrical and mechanical specifications for capacitance, voltage rating, tolerance, ESR, package configuration, and physical dimensions, ensuring direct substitution capability in chassis-mounted general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can ALS80A184KF025 directly replace ALS71H184KF025 in existing designs?

A: Yes. Both parts share identical capacitance (180000 µF), voltage rating (25 V), tolerance (±20%), ESR (13 mOhm @ 100Hz), package type (Radial, Can - Screw Terminals), and physical dimensions (2.008" Dia × 4.213" Height with 0.874" lead spacing). Direct substitution is electrically and mechanically compatible.

Q: What are the differences between these two part numbers?

A: The primary differences are operating temperature range (ALS71H: -40°C to 85°C vs. ALS80A: -40°C to 105°C), lifetime rating (ALS71H: 18000 Hrs @ 85°C vs. ALS80A: 7000 Hrs @ 105°C), and ripple current specifications (ALS71H: 20.3 A @ 100 Hz / 21.4 A @ 10 kHz vs. ALS80A: 17.6 A @ 100 Hz / 18.7 A @ 10 kHz).

Q: Are both parts RoHS compliant?

A: Yes. Both ALS71H184KF025 and ALS80A184KF025 are ROHS3 compliant and REACH unaffected.

Q: What mounting configuration do these capacitors use?

A: Both parts are chassis-mounted aluminum electrolytic capacitors with radial, can-screw terminal configuration. Lead spacing is 0.874" (22.20mm) with identical physical dimensions.

Q: Which part should I select for high-temperature applications?

A: The ALS80A184KF025 supports operation up to 105°C, compared to 85°C maximum for the ALS71H184KF025. Select ALS80A184KF025 for applications requiring extended temperature operation.

Q: Are these parts suitable for general-purpose applications?

A: Yes. Both parts are classified for general-purpose applications and are rated for -40°C to 85°C (ALS71H) or -40°C to 105°C (ALS80A) operation with appropriate ripple current handling at low and high frequencies.
