Substitute Part Grouping Explanation

Substitution of the PEG124PD247VQL1 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

Capacitance value: 47 µF (exact match)
Voltage rating: 100 V (exact match)
ESR: 1.5 Ohm @ 100 Hz (exact match)
Polarization: Polar (exact match)
Tolerance: -10%, +30% (exact match)

Mechanical Equivalence Requirements:

Package type: Axial, Can (exact match)
Mounting type: Through Hole (exact match)
Physical dimensions: 0.512" Dia × 1.142" L (13.00 mm × 29.00 mm) (exact match)

Environmental & Compliance Requirements:

Operating temperature range: -40°C ~ 105°C (exact match)
RoHS3 compliance (exact match)

Substitute parts must belong to the same PEG124 series and maintain all specified electrical and mechanical parameters. Lifetime and ripple current characteristics may vary within the same electrical specification class.

Engineering Selection Recommendations

The PEG124PD247VQE4 is a direct electrical and mechanical substitute for the PEG124PD247VQL1. Both components share identical capacitance, voltage rating, ESR, tolerance, physical dimensions, and operating temperature range. Both are ROHS3 compliant and manufactured by KEMET within the same PEG124 series.

The primary distinction between these parts is product status and lifetime rating. The PEG124PD247VQL1 is discontinued at DiGi Electronics, while the PEG124PD247VQE4 maintains active product status with current inventory availability. The substitute part offers extended lifetime characteristics (5000 Hrs @ 105°C versus 2000 Hrs @ 125°C), providing enhanced reliability for long-term applications.

Selection of the PEG124PD247VQE4 is appropriate for direct replacement in existing designs without circuit modification or re-qualification, as all critical electrical and mechanical parameters remain equivalent.

Frequently Asked Questions (FAQ)

Q: Can the PEG124PD247VQE4 be used as a direct replacement for the PEG124PD247VQL1?

A: Yes. Both components are electrically and mechanically equivalent. They share identical capacitance (47 µF), voltage rating (100 V), ESR (1.5 Ohm @ 100 Hz), physical dimensions (0.512" Dia × 1.142" L), and operating temperature range (-40°C ~ 105°C). No circuit modification is required.

Q: What is the primary reason for substitution?

A: The PEG124PD247VQL1 is discontinued at DiGi Electronics. The PEG124PD247VQE4 is an active product with equivalent specifications and current inventory availability.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical axial, can package dimensions of 0.512" diameter and 1.142" maximum seated height (13.00 mm × 29.00 mm). Through-hole mounting compatibility is maintained.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PEG124PD247VQL1 and PEG124PD247VQE4 are ROHS3 compliant and REACH unaffected.

Q: What is the difference in lifetime ratings?

A: The PEG124PD247VQL1 is rated for 2000 hours at 125°C. The PEG124PD247VQE4 is rated for 5000 hours at 105°C. The substitute part provides extended operational life at the maximum operating temperature of the specified range.

Q: Are the ripple current specifications the same?

A: Low-frequency ripple current is identical at 206 mA @ 100 Hz. High-frequency ripple current differs: the main part is rated 214.24 mA @ 100 kHz, while the substitute is rated 580 mA @ 5 kHz. Both specifications remain within acceptable operating parameters for general-purpose applications.

Q: Can these parts be used interchangeably on PCBs?
