Parameter Comparison

Engineering Selection Recommendations

Both the ALS80C114QC040 and ALS80A114QC040 are active production components manufactured by KEMET with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and inventory levels rather than technical performance differences.

Primary Selection (ALS80C114QC040): Use when available. Current inventory of 993 units supports standard procurement cycles.

Substitute Selection (ALS80A114QC040): Use when the primary part is unavailable or when inventory constraints require alternative sourcing. Current inventory of 877 units is available. This part provides identical electrical performance and mechanical compatibility.

Both parts are suitable for direct substitution in chassis-mounted applications requiring 110000 µF capacitance at 40 V with screw terminal connections. No circuit redesign or board layout modifications are required when switching between these parts.

Frequently Asked Questions (FAQ)

Q: Can ALS80A114QC040 be used as a direct replacement for ALS80C114QC040?

A: Yes. Both parts are electrically and mechanically identical. All critical parameters including capacitance, voltage rating, ESR, ripple current ratings, physical dimensions, and lead spacing are identical. Both are ROHS3 compliant and in active production.

Q: What is the difference between the ALS80C and ALS80A base product numbers?

A: The base product number designation (ALS80C versus ALS80A) indicates a variant within the ALS80 series. For the 114QC040 configuration, both variants provide identical electrical and mechanical specifications.

Q: Are the screw terminal connections identical on both parts?

A: Yes. Both ALS80C114QC040 and ALS80A114QC040 use identical radial can screw terminal packages with 1.252" (31.80 mm) lead spacing. No terminal adapter or connection modification is required.

Q: Do both parts have the same physical footprint?

A: Yes. Both parts have identical dimensions: 3.543" (90.00 mm) diameter and 2.717" (69.00 mm) seated height. Both mount identically in chassis applications.

Q: What is the ESR specification and why is it important?

A: Both parts have 13 mOhm ESR at 100 Hz. ESR (Equivalent Series Resistance) affects ripple current handling and heat dissipation. Identical ESR values ensure equivalent thermal performance in power supply circuits.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical regulatory certifications. Both are suitable for applications with equivalent compliance requirements.

Q: What is the ripple current rating and how does it apply?

A: Both parts support 19.4 A ripple current at 100 Hz and 20.4 A at 10 kHz. These ratings define the maximum AC current the capacitor can handle without exceeding temperature limits. Both parts have identical ripple current specifications.

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

A: Yes. No circuit modifications, PCB layout changes, or terminal reconfiguration are required. Both parts are pin-compatible and electrically equivalent for all applications using the ALS80C114QC040.
