PEG124VG2220QL1 Equivalent & Substitute Parts

Part Overview

The PEG124VG2220QL1 is a 22 µF, 400 V aluminum electrolytic capacitor in axial, can package configuration manufactured by KEMET. This component is designed for general-purpose applications requiring stable capacitance and low equivalent series resistance across a wide operating temperature range. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility with existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PEG124VG2220QL1 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Capacitance value: 22 µF
• Rated voltage: 400 V
• Package type: Axial, Can
• Mounting type: Through Hole
• ESR specification: 2.7 Ohm @ 100 Hz
• Lifetime rating: 5000 Hrs @ 105°C
• Operating temperature range: -40°C ~ 105°C
• RoHS3 compliance

Allowable Variations:

• Tolerance: Substitute tolerance must encompass or be compatible with the original ±20% specification
• Ripple current ratings: Substitute must meet or exceed the original ripple current specifications
• Physical dimensions: Substitute axial length may vary provided through-hole mounting compatibility is maintained

The PEG124VG2220QE4 qualifies as a direct substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The PEG124VG2220QE4 is the qualified substitute for the discontinued PEG124VG2220QL1. Both components are manufactured by KEMET within the PEG124 series and maintain identical electrical specifications for capacitance, voltage rating, ESR, lifetime, and operating temperature range.

Compliance Status: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Product Availability: The PEG124VG2220QE4 maintains active product status with current inventory availability, whereas the original part is discontinued. Selection of the substitute part ensures continued supply chain access and design continuity.

Physical Compatibility: The substitute part maintains the same 0.630" (16.00 mm) diameter specification. The axial length differs (37.00 mm versus 82.00 mm for the original), which may affect board layout. Through-hole mounting compatibility is maintained, allowing direct substitution in PCB designs with appropriate lead spacing verification.

Electrical Performance: The substitute part meets or exceeds the original specifications for low-frequency ripple current (209 mA @ 100 Hz). High-frequency ripple current is reduced (500 mA @ 5 kHz versus 1.4 A @ 5 kHz), which is acceptable for applications not requiring the maximum high-frequency ripple current rating of the original part.

Frequently Asked Questions (FAQ)

Q: Can the PEG124VG2220QE4 be used as a direct replacement for the PEG124VG2220QL1?

A: Yes. Both components share identical capacitance (22 µF), voltage rating (400 V), ESR (2.7 Ohm @ 100 Hz), lifetime (5000 Hrs @ 105°C), and operating temperature range (-40°C ~ 105°C). Through-hole axial mounting is maintained on both parts. The substitute is electrically and mechanically compatible for direct substitution.

Q: What is the difference in tolerance between the original and substitute parts?

A: The original PEG124VG2220QL1 specifies ±20% tolerance. The substitute PEG124VG2220QE4 specifies -10%, +30% tolerance. The substitute tolerance range encompasses the original specification, ensuring compatibility with circuit designs based on the original tolerance band.

Q: How does the physical size difference affect board layout?

A: The original part has a maximum seated height of 82.00 mm. The substitute part has an axial length of 37.00 mm. Both maintain the same 0.630" (16.00 mm) diameter. The reduced length of the substitute part may require PCB layout adjustment. Verify lead spacing and component clearance in your specific application before implementation.

Q: Are there any ripple current limitations with the substitute part?

A: The substitute part maintains the low-frequency ripple current specification (209 mA @ 100 Hz). High-frequency ripple current is reduced from 1.4 A @ 5 kHz to 500 mA @ 5 kHz. For applications requiring the full 1.4 A high-frequency ripple current rating, the substitute part may not be suitable. Verify your circuit's high-frequency ripple current requirements before selection.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both the PEG124VG2220QL1 and PEG124VG2220QE4 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement and use.

Q: What is the inventory status of each part?

A: The original PEG124VG2220QL1 is discontinued at DiGi Electronics with 1693 pieces listed as new original in stock. The substitute PEG124VG2220QE4 maintains active product status with 751 pieces currently in stock, ensuring continued availability for new designs and replacements.
