Key Parameters

Substitute Part Grouping Explanation

Substitution of the PEG124GA2680QL1 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 68 µF (exact match required)
• Voltage rating: 16 V (exact match required)
• ESR @ 100 Hz: 2.4 Ohm (exact match required)
• Lifetime @ Temperature: 2000 Hrs @ 125°C (exact match required)
• Operating temperature range: -40°C ~ 125°C (exact match required)
• Tolerance: -10%, +30% (exact match required)

Mechanical Equivalence Criteria:

• Package type: Axial, Can (exact match required)
• Physical dimensions: 0.394" Dia x 0.787" L / 10.00mm x 20.00mm (exact match required)
• Mounting type: Through Hole (exact match required)

Compliance Criteria:

• RoHS3 Compliant status (maintained across all substitutes)

Substitute parts are grouped based on product status and availability. All identified substitutes maintain full electrical and mechanical compatibility with the original PEG124GA2680QL1 specification.

Engineering Selection Recommendations

PEG124GA2680QE4 (MFR Recommended Substitute)

The PEG124GA2680QE4 is the manufacturer-recommended substitute for the discontinued PEG124GA2680QL1. This part maintains full electrical and mechanical equivalence across all critical parameters. The component carries active product status and is ROHS3 compliant. The ripple current rating at 5 kHz is reduced to 360 mA compared to the original 950 mA specification. Selection of this substitute is appropriate for applications where the lower high-frequency ripple current rating does not exceed circuit requirements.

PEG124GA2680QT1 (Upgrade Substitute)

The PEG124GA2680QT1 provides complete electrical and mechanical compatibility with the original PEG124GA2680QL1. This part maintains the full ripple current specification of 950 mA @ 5 kHz, matching the original component exactly. The component carries active product status and is ROHS3 compliant. This substitute is suitable for applications requiring the complete original ripple current performance specification.

Both substitute parts are manufactured by KEMET within the PEG124 series and maintain all compliance certifications of the original component.

Frequently Asked Questions (FAQ)

Q: Can PEG124GA2680QE4 be used as a direct replacement for PEG124GA2680QL1?

A: The PEG124GA2680QE4 is electrically and mechanically equivalent to the PEG124GA2680QL1 across all core parameters including capacitance, voltage rating, ESR, lifetime, and operating temperature range. The ripple current rating at 5 kHz is 360 mA versus 950 mA in the original. Direct substitution is valid provided the circuit design does not require the higher ripple current specification.

Q: What is the difference between PEG124GA2680QE4 and PEG124GA2680QT1?

A: Both parts are electrically and mechanically equivalent to the original PEG124GA2680QL1. The primary difference is the ripple current rating at 5 kHz: PEG124GA2680QE4 is rated at 360 mA, while PEG124GA2680QT1 is rated at 950 mA, matching the original specification. Selection depends on the high-frequency ripple current requirements of the application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both PEG124GA2680QE4 and PEG124GA2680QT1 are ROHS3 compliant, maintaining the compliance status of the original PEG124GA2680QL1.

Q: Do the substitute parts have the same physical dimensions as the original?

A: Yes. All substitute parts maintain the identical physical dimensions of 0.394" Dia x 0.787" L (10.00mm x 20.00mm) and are configured as through-hole mounted axial, can package components.

Q: What is the product status of the substitute parts?

A: Both PEG124GA2680QE4 and PEG124GA2680QT1 carry active product status, ensuring continued availability and supply chain support.

Q: Are the tolerance specifications identical across all parts?

A: Yes. All parts, including the original and both substitutes, maintain a tolerance specification of -10%, +30%.
