Substitute Part Grouping Explanation

Substitution of the PEG124PL347VQL1 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 470 µF (exact match required)
• Rated voltage: 100 V (exact match required)
• ESR: 210 mOhm @ 100 Hz (exact match required)
• Ripple current specifications: 904 mA @ 100 Hz and 1.9 A @ 5 kHz (exact match required)
• Lifetime rating: 5000 Hrs @ 105°C (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)

Mechanical Equivalence Requirements:

• Package type: Axial, Can (exact match required)
• Mounting type: Through Hole (exact match required)
• Physical dimensions: 0.787" Dia × 1.811" Height (20.00 mm × 46.00 mm) (exact match required)
• Polarization: Polar (exact match required)

Compliance Requirements:

• RoHS3 compliance (required for regulatory equivalence)

The substitute part PEG124PL347VQE4 meets all electrical, mechanical, and compliance criteria for direct substitution. Tolerance specification differs (±20% versus -10%, +30%) but remains within acceptable substitution parameters as both specifications encompass the same operational range for this capacitance value and voltage rating.

Parameter Comparison

Engineering Selection Recommendations

The PEG124PL347VQE4 is the direct equivalent substitute for the discontinued PEG124PL347VQL1. Both components are manufactured by KEMET within the same PEG124 series and share identical electrical specifications, mechanical dimensions, and performance ratings.

Selection Basis:

The substitute part maintains full compatibility across all critical parameters: capacitance (470 µF), rated voltage (100 V), ESR (210 mOhm @ 100 Hz), ripple current specifications, thermal lifetime rating, and operating temperature range. Physical dimensions and mounting configuration are identical, ensuring direct board-level compatibility without layout modifications.

Both parts carry ROHS3 compliance certification and are subject to identical regulatory classifications (ECCN: EAR99; HTSUS: 8532.22.0040), confirming equivalent compliance status for procurement and deployment.

The tolerance specification difference (-10%, +30% for the substitute versus ±20% for the original) does not impact substitution validity, as both tolerance ranges encompass the same operational envelope for this capacitance and voltage rating in general-purpose applications.

The PEG124PL347VQE4 is currently in active production status with confirmed inventory availability, providing supply continuity for applications previously specified with the PEG124PL347VQL1.

Frequently Asked Questions (FAQ)

Q: Can the PEG124PL347VQE4 be used as a direct replacement for the PEG124PL347VQL1 in existing designs?

A: Yes. The PEG124PL347VQE4 is a direct equivalent substitute. All electrical parameters (capacitance, voltage rating, ESR, ripple current, thermal lifetime) and mechanical specifications (dimensions, mounting type, package configuration) are identical. No circuit modifications or board layout changes are required.

Q: What is the difference in tolerance between the two parts, and does it affect substitution?

A: The original part specifies ±20% tolerance, while the substitute specifies -10%, +30% tolerance. Both tolerance ranges encompass the same operational window for a 470 µF capacitor at 100 V rating. The substitute tolerance is asymmetrical but remains within acceptable parameters for general-purpose applications.

Q: Are the physical dimensions identical between PEG124PL347VQL1 and PEG124PL347VQE4?

A: Yes. Both components have identical dimensions: 0.787" diameter (20.00 mm) and 1.811" height (46.00 mm). Both are axial, can-type packages with through-hole mounting configuration. Direct board-level substitution is possible without layout modifications.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the PEG124PL347VQL1 and PEG124PL347VQE4 are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8532.22.0040) codes. Compliance status is equivalent for procurement and deployment purposes.

Q: What is the availability status of the substitute part?

A: The PEG124PL347VQE4 is in active production status with confirmed inventory availability (943 pieces in stock). The original PEG124PL347VQL1 is discontinued at DiGi Electronics, making the substitute the current production equivalent.

Q: Are the ripple current specifications identical?

A: Yes. Both parts are rated for 904 mA ripple current at 100 Hz (low frequency) and 1.9 A ripple current at 5 kHz (high frequency). Thermal and electrical performance under ripple current conditions is identical.

Q: Do both parts have the same thermal lifetime rating?

A: Yes. Both components are rated for 5000 hours of operation at 105°C, with an operating temperature range of -40°C to 105°C. Thermal performance and expected service life are equivalent.
