Substitute Part Grouping Explanation

Substitution eligibility for the ALC80D102DF250 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance: 1000 µF (exact match required)
• Voltage Rating: 250 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 178 mOhm nominal (within manufacturer specification tolerance)
• Lifetime: 8000 Hrs @ 105°C (exact match required)
• Operating Temperature: -40°C ~ 105°C (exact match required)
• Ripple Current specifications: 3.46 A @ 100 Hz and 7.52 A @ 10 kHz (exact match required)

Mechanical Parameters:

• Package Type: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Polarization: Polar (exact match required)

The ALC80D102DF250 belongs to the KEMET ALC80 series. Substitute parts must originate from the same series family and maintain identical electrical performance characteristics and physical dimensions to ensure direct board-level compatibility without circuit redesign or PCB modification.

Parameter Comparison

Engineering Selection Recommendations

ALC80A102DF250 as Primary Substitute:

The ALC80A102DF250 qualifies as a direct parametric equivalent to the ALC80D102DF250. Both components are manufactured by KEMET within the ALC80 series and maintain identical electrical specifications across capacitance, voltage rating, tolerance, lifetime rating, operating temperature range, and ripple current performance. ESR values are equivalent within manufacturer tolerance (178 mOhm versus 178.2 mOhm @ 100Hz). Mechanical dimensions, lead spacing, and package configuration are identical, confirming direct board-level compatibility without PCB modification.

Both parts maintain Active product status and ROHS3 compliance, satisfying regulatory and supply chain requirements. The ALC80A102DF250 currently maintains higher inventory availability (1668 Pcs) compared to the ALC80D102DF250 (873 Pcs), making it suitable for applications where supply continuity is a consideration.

Selection between these two parts is determined by availability, lead time, and procurement cost rather than technical performance differentiation.

Frequently Asked Questions (FAQ)

Q: Can ALC80A102DF250 be used as a direct replacement for ALC80D102DF250 on existing PCBs?

A: Yes. The ALC80A102DF250 is electrically and mechanically equivalent. Lead spacing (0.394" / 10.00 mm), package type (Radial, Can - Snap-In), and all electrical parameters are identical. No PCB modification or circuit redesign is required.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is determined by exact equivalence in: capacitance (1000 µF), voltage rating (250 V), tolerance (±20%), ESR specification (178 mOhm @ 100Hz), lifetime rating (8000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), ripple current ratings (3.46 A @ 100 Hz, 7.52 A @ 10 kHz), lead spacing (10.00 mm), package type (Radial, Can - Snap-In), and mounting type (Through Hole).

Q: Are there differences in ESR between ALC80D102DF250 and ALC80A102DF250?

A: ESR values are 178 mOhm and 178.2 mOhm respectively. This 0.2 mOhm difference falls within manufacturer tolerance specifications and does not affect circuit performance or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ALC80D102DF250 and ALC80A102DF250 are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99. Compliance certifications are identical.

Q: What is the difference between the base product numbers ALC80D and ALC80A?

A: The base product numbers indicate internal KEMET series designations. Both ALC80D and ALC80A variants within the ALC80 series maintain identical electrical and mechanical specifications for the 1000 µF 250 V configuration. Substitution is valid between these variants when all other parameters match exactly.

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

A: Yes. Both parts are rated for 3.46 A ripple current @ 100 Hz and 7.52 A ripple current @ 10 kHz, supporting applications requiring sustained AC current handling at these frequency ranges.

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

A: The maximum operating temperature is 105°C. Lifetime rating is specified as 8000 hours at this temperature. Operating below 105°C extends component life beyond the specified 8000-hour rating.
