ALS71A114KF040 Equivalent & Substitute Parts

Part Overview

The ALS71A114KF040 is a 110000 µF, 40 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 in chassis-mount configurations. The part maintains an active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory constraints require component alternatives that maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71A114KF040 and ALS70A114KF040 are active products manufactured by KEMET with full RoHS3 compliance and REACH unaffected status. The parts are electrically and mechanically identical across all specified parameters, including capacitance, voltage rating, ESR, ripple current ratings, thermal lifetime, and physical dimensions.

Selection between these parts should be based on:

1. Inventory Availability: The ALS70A114KF040 currently has 1070 pieces in stock compared to 851 pieces for the ALS71A114KF040.

2. Series Designation: The ALS71A114KF040 belongs to the ALS71 series, while the ALS70A114KF040 belongs to the ALS70 series. Both series maintain identical electrical and mechanical specifications for this capacitance and voltage rating.

3. Compliance Requirements: Both parts satisfy identical regulatory requirements (RoHS3, REACH, EAR99 ECCN classification, HTSUS code 8532.22.0055).

4. Application Continuity: Direct substitution is supported for general-purpose applications without circuit redesign or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can ALS70A114KF040 be used as a direct replacement for ALS71A114KF040?

A: Yes. The ALS70A114KF040 is a parametric equivalent with identical electrical specifications (110000 µF, 40 V, ±20% tolerance, 14 mOhm ESR @ 100Hz, 18000 Hrs @ 85°C) and mechanical dimensions (2.008" diameter, 4.213" height, 0.874" lead spacing, radial can with screw terminals). Both parts are chassis-mount configurations with identical ripple current ratings and operating temperature ranges.

Q: Are there any differences in the series designation between ALS71 and ALS70?

A: The series designation differs (ALS71 versus ALS70), but for this specific capacitance and voltage rating, all electrical and mechanical parameters are identical. Both series are active products with full RoHS3 compliance.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by exact matching of: capacitance (110000 µF), voltage rating (40 V), tolerance (±20%), ESR (14 mOhm @ 100Hz), thermal lifetime (18000 Hrs @ 85°C), operating temperature range (-40°C to 85°C), ripple current specifications (19.9 A @ 100 Hz, 21.4 A @ 10 kHz), package type (radial can with screw terminals), mounting configuration (chassis mount), and physical dimensions (lead spacing, diameter, height).

Q: Are both parts RoHS3 compliant?

A: Yes. Both ALS71A114KF040 and ALS70A114KF040 are ROHS3 compliant with REACH unaffected status.

Q: What is the moisture sensitivity level for these capacitors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited moisture sensitivity protection.

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

A: Yes. Both parts are rated for 19.9 A ripple current at 100 Hz and 21.4 A ripple current at 10 kHz, supporting high-ripple-current general-purpose applications.
