Key Parameters

Substitute Part Grouping Explanation

Substitution of the PEG124KA2330QL1 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 33 µF (within tolerance range -10%, +30%)
• Voltage rating: 40 V (minimum)
• ESR: 2.9 Ohm @ 100 Hz
• Lifetime specification: 2000 Hrs @ 125°C
• Operating temperature range: -40°C ~ 125°C
• Ripple current capability: 153 mA @ 100 Hz and 1.1 A @ 5 kHz

Mechanical Equivalence Requirements:

• Package type: Axial, Can
• Physical dimensions: 0.394" Dia x 20.00 mm L (10.00 mm x 20.00 mm)
• Mounting type: Through Hole
• Polarization: Polar

Compliance Requirements:

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99

Substitute parts must satisfy all electrical, mechanical, and compliance parameters to ensure direct functional replacement without circuit redesign or board layout modification.

Engineering Selection Recommendations

PEG124KA2330QE4 (MFR Recommended Substitute)

The PEG124KA2330QE4 is the manufacturer-recommended substitute for the discontinued PEG124KA2330QL1. This part maintains electrical and mechanical equivalence across all critical parameters with the exception of ripple current at 5 kHz, which is specified at 390 mA compared to 1.1 A in the original part. This substitute is suitable for applications where high-frequency ripple current demand does not exceed 390 mA @ 5 kHz. The part carries active product status and maintains full ROHS3 compliance and REACH unaffected designation.

PEG124KA2330QT1 (Upgrade Substitute)

The PEG124KA2330QT1 provides complete electrical and mechanical equivalence to the PEG124KA2330QL1, including identical ripple current specifications at both 100 Hz (153 mA) and 5 kHz (1.1 A). This part is supplied in bulk packaging and carries active product status. The PEG124KA2330QT1 is suitable for direct replacement in all applications requiring the full ripple current capability of the original component. Full ROHS3 compliance and REACH unaffected status are maintained.

Selection Criteria

Component selection between the two substitutes depends on application ripple current requirements at 5 kHz. Applications requiring ripple current handling of 1.1 A @ 5 kHz must use PEG124KA2330QT1. Applications with ripple current demands not exceeding 390 mA @ 5 kHz may use either substitute. Both parts are active products with equivalent compliance certifications and identical mechanical form factors.

Frequently Asked Questions (FAQ)

Q: Can PEG124KA2330QE4 be used as a direct replacement for PEG124KA2330QL1?

A: The PEG124KA2330QE4 is electrically and mechanically compatible with the PEG124KA2330QL1 for applications where the ripple current requirement at 5 kHz does not exceed 390 mA. The original part specifies 1.1 A @ 5 kHz. If your circuit requires this full ripple current capacity, use PEG124KA2330QT1 instead.

Q: What is the difference between PEG124KA2330QE4 and PEG124KA2330QT1?

A: Both parts are KEMET PEG124 series aluminum electrolytic capacitors with identical capacitance (33 µF), voltage rating (40 V), ESR (2.9 Ohm @ 100 Hz), and physical dimensions. The primary difference is ripple current capability at 5 kHz: PEG124KA2330QE4 is rated for 390 mA, while PEG124KA2330QT1 is rated for 1.1 A. PEG124KA2330QT1 is supplied in bulk packaging.

Q: Are all three parts (PEG124KA2330QL1, PEG124KA2330QE4, PEG124KA2330QT1) mechanically identical?

A: Yes. All three parts share identical physical dimensions of 0.394" diameter by 0.787" length (10.00 mm x 20.00 mm), axial can package configuration, and through-hole mounting type. They are mechanically interchangeable without board layout modification.

Q: Do the substitute parts maintain the same compliance certifications as the original?

A: Yes. Both PEG124KA2330QE4 and PEG124KA2330QT1 are ROHS3 compliant, REACH unaffected, and carry the same ECCN (EAR99) and HTSUS (8532.22.0020) classifications as the original PEG124KA2330QL1.

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

A: All three parts operate across the temperature range of -40°C to 125°C with a specified lifetime of 2000 hours at 125°C.

Q: Why is the PEG124KA2330QL1 discontinued?

A: The PEG124KA2330QL1 is discontinued at DiGi Electronics. The active substitute parts PEG124KA2330QE4 and PEG124KA2330QT1 provide equivalent functionality and are available for new designs and replacement applications.
