PEG124PA147CQL1 Equivalent & Substitute Parts

Part Overview

The PEG124PA147CQL1 is a 4.7 µF, 100 V aluminum electrolytic capacitor in axial, can package configuration manufactured by KEMET. This component is designed for general-purpose applications requiring through-hole mounting with specified ripple current handling and thermal stability across the operating temperature range of -40°C to 105°C. The part is discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain electrical and mechanical compatibility with the original design specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PEG124PA147CQL1 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 4.7 µF (exact match)
• Voltage rating: 100 V (exact match)
• Tolerance: -10%, +30% (exact match)
• ESR: 16 Ohm @ 100 Hz (exact match)
• Lifetime: 5000 Hrs @ 105°C (exact match)
• Operating temperature range: -40°C ~ 105°C (exact match)

Mechanical Equivalence Requirements:

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

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.

Parameter Comparison

Engineering Selection Recommendations

PEG124PA147CQE4 (MFR Recommended Substitute): This part maintains electrical and mechanical equivalence with the original PEG124PA147CQL1 across all critical parameters including capacitance, voltage rating, ESR, and operating temperature range. The component is currently in active production status, ensuring long-term availability. RoHS3 compliance and REACH unaffected status align with regulatory requirements. The ripple current specification at high frequency (200 mA @ 5 kHz) is lower than the original part; this substitution is appropriate for applications where high-frequency ripple current demand does not exceed 200 mA @ 5 kHz.

PEG124PA147CQT1 (Upgrade Substitute): This part provides complete electrical and mechanical equivalence to the original PEG124PA147CQL1, including identical ripple current specifications (650 mA @ 5 kHz). The component is in active production status with bulk packaging availability. RoHS3 compliance and REACH unaffected status satisfy regulatory requirements. This substitution is appropriate for applications requiring the full ripple current handling capability of the original design.

Both substitute parts are manufactured by KEMET within the PEG124 series and maintain identical physical dimensions, mounting configuration, and thermal characteristics. Selection between the two substitutes depends on high-frequency ripple current requirements in the application circuit.

Frequently Asked Questions (FAQ)

Q: Can PEG124PA147CQE4 be used as a direct replacement for PEG124PA147CQL1?

A: PEG124PA147CQE4 is electrically and mechanically equivalent to PEG124PA147CQL1 across all specified parameters except high-frequency ripple current. The substitute part supports 200 mA @ 5 kHz compared to 650 mA @ 5 kHz in the original. Direct replacement is appropriate if the application circuit does not require ripple current handling exceeding 200 mA at 5 kHz.

Q: What is the difference between PEG124PA147CQE4 and PEG124PA147CQT1?

A: Both parts are electrically and mechanically equivalent to the original PEG124PA147CQL1. The primary difference is high-frequency ripple current specification: PEG124PA147CQE4 supports 200 mA @ 5 kHz, while PEG124PA147CQT1 supports 650 mA @ 5 kHz, matching the original part's capability. Selection depends on application ripple current requirements.

Q: Are the substitute parts physically compatible with the original PCB layout?

A: Yes. Both substitute parts maintain identical physical dimensions (0.394" Dia x 0.787" L / 10.00 mm x 20.00 mm), axial can package configuration, and through-hole mounting type. No PCB layout modification is required.

Q: Do the substitute parts meet the same compliance standards as the original?

A: Yes. Both PEG124PA147CQE4 and PEG124PA147CQT1 are RoHS3 compliant, REACH unaffected, and classified as EAR99 under ECCN, matching the original part's regulatory status.

Q: What is the operating temperature range for the substitute parts?

A: Both substitute parts operate across the identical temperature range of -40°C to 105°C with 5000 hours lifetime at 105°C, matching the original PEG124PA147CQL1 specification.

Q: Can these parts be used interchangeably in the same circuit?

A: PEG124PA147CQT1 provides complete interchangeability with the original part. PEG124PA147CQE4 is interchangeable provided the application circuit does not require high-frequency ripple current exceeding 200 mA @ 5 kHz.
