Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PEG124HB3100QL1 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance: 100 µF (exact match required)
• Voltage Rating: 25 V (exact match required)
• Tolerance: -10%, +30% (exact match required)
• ESR @ 100 Hz: 1.2 Ohm (exact match required)
• Lifetime @ Temperature: 2000 Hrs @ 125°C (exact match required)
• Operating Temperature Range: -40°C ~ 125°C (exact match required)
• Package Type: Axial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Physical Dimensions: 0.394" Dia x 1.142" L / 10.00mm x 29.00mm (exact match required)
• Polarization: Polar (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Substitute parts may vary in ripple current specifications at specific frequencies and product status, provided all critical parameters remain identical. All substitute parts are manufactured by KEMET within the PEG124 series.

Parameter Comparison

Engineering Selection Recommendations

PEG124HB3100QE4 is the manufacturer-recommended substitute for the discontinued PEG124HB3100QL1. This part maintains all critical electrical parameters and physical dimensions. The PEG124HB3100QE4 carries active product status and is ROHS3 compliant. The ripple current specification at 5 kHz is reduced to 560 mA compared to the original 1.5 A specification. This part is suitable for applications where the lower ripple current rating does not exceed circuit requirements.

PEG124HB3100QT1 is an upgrade substitute that maintains the original ripple current specification of 1.5 A @ 5 kHz. This part carries active product status and is ROHS3 compliant. The PEG124HB3100QT1 is packaged in bulk format and provides equivalent electrical performance to the original PEG124HB3100QL1 across all specified parameters.

Both substitute parts are manufactured by KEMET within the PEG124 series and satisfy regulatory compliance requirements including ROHS3 and REACH standards.

Frequently Asked Questions (FAQ)

Q: Can PEG124HB3100QE4 be used as a direct replacement for PEG124HB3100QL1?

A: The PEG124HB3100QE4 is electrically and mechanically compatible with the PEG124HB3100QL1 for all critical parameters including capacitance, voltage rating, tolerance, ESR, lifetime, operating temperature, and physical dimensions. The ripple current specification at 5 kHz is 560 mA versus 1.5 A in the original part. Direct substitution is valid when the circuit design does not require ripple current handling exceeding 560 mA at 5 kHz.

Q: What is the difference between PEG124HB3100QE4 and PEG124HB3100QT1?

A: Both parts are equivalent substitutes for the PEG124HB3100QL1 with identical capacitance, voltage rating, tolerance, ESR, lifetime, operating temperature, and physical dimensions. The primary difference is ripple current specification at 5 kHz: PEG124HB3100QE4 is rated for 560 mA, while PEG124HB3100QT1 is rated for 1.5 A. The PEG124HB3100QT1 maintains the original ripple current specification of the discontinued part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The PEG124HB3100QE4 and PEG124HB3100QT1 are both ROHS3 compliant and REACH unaffected, matching the compliance status of the original PEG124HB3100QL1.

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

A: Yes. All substitute parts maintain the identical physical dimensions of 0.394" diameter by 1.142" length (10.00mm x 29.00mm) and are packaged as axial, can components for through-hole mounting.

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

A: Both PEG124HB3100QE4 and PEG124HB3100QT1 carry active product status, ensuring continued availability and supply chain support. The original PEG124HB3100QL1 is discontinued at DiGi Electronics.

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

A: The PEG124HB3100QT1 provides full interchangeability with the original PEG124HB3100QL1 across all electrical and mechanical specifications. The PEG124HB3100QE4 is interchangeable provided the circuit design accommodates the reduced ripple current rating of 560 mA at 5 kHz.
