PEG124MA2220QL1 Equivalent & Substitute Parts

Part Overview

The PEG124MA2220QL1 is a 22 µF, 63 V aluminum electrolytic capacitor in axial, can package manufactured by KEMET. This component is classified as discontinued at DiGi Electronics, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement. The part operates across a temperature range of -40°C to 125°C with a rated lifetime of 2000 hours at 125°C, making it suitable for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Substitute Part Grouping Explanation

Substitution of the PEG124MA2220QL1 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Capacitance: 22 µF (exact match required)
• Voltage Rating: 63 V (exact match required)
• Tolerance: -10%, +30% (exact match required)
• ESR: 3.4 Ohm @ 100 Hz (exact match required)
• Lifetime: 2000 Hrs @ 125°C (exact match required)
• Operating Temperature: -40°C ~ 125°C (exact match required)
• Package Type: Axial, Can (exact match required)
• Physical Dimensions: 10.00 mm x 20.00 mm (exact match required)
• Mounting: Through Hole (exact match required)
• Polarization: Polar (exact match required)

The substitute parts identified below meet all mandatory equivalence criteria. Differences in ripple current capacity at high frequency (5 kHz) and product status (active vs. discontinued) do not affect functional substitution for applications operating within the specified low-frequency ripple current rating of 134 mA @ 100 Hz.

Parameter Comparison

Engineering Selection Recommendations

PEG124MA2220QE4 is the primary recommended substitute. This part maintains full electrical and mechanical equivalence to the PEG124MA2220QL1 while offering active product status and higher inventory availability (1998 pcs in stock). The PEG124MA2220QE4 provides enhanced ripple current capacity at high frequency (430 mA @ 5 kHz), which represents a performance improvement without introducing any compatibility concerns for applications designed around the original part specifications.

PEG124MA2220QT1 is an alternative substitute with identical core electrical parameters and active product status. This part offers superior high-frequency ripple current performance (1.1 A @ 5 kHz), providing additional design margin for applications subject to higher-frequency ripple conditions. Both substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance equivalent to the original part.

Selection between PEG124MA2220QE4 and PEG124MA2220QT1 should be based on procurement availability and application-specific ripple current requirements at frequencies above 100 Hz. For applications operating strictly within the specified 134 mA @ 100 Hz ripple current envelope, both substitutes are functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can PEG124MA2220QE4 or PEG124MA2220QT1 be used as direct replacements for PEG124MA2220QL1 in existing designs?

A: Yes. Both substitute parts are direct replacements. They maintain identical capacitance (22 µF), voltage rating (63 V), tolerance (-10%, +30%), ESR (3.4 Ohm @ 100 Hz), lifetime (2000 Hrs @ 125°C), operating temperature range (-40°C ~ 125°C), physical dimensions (10.00 mm x 20.00 mm), and mounting configuration (through-hole axial). No circuit modifications or PCB layout changes are required.

Q: What is the difference between PEG124MA2220QE4 and PEG124MA2220QT1?

A: The primary difference is ripple current capacity at high frequency (5 kHz). PEG124MA2220QE4 supports 430 mA @ 5 kHz, while PEG124MA2220QT1 supports 1.1 A @ 5 kHz. Both parts are electrically identical at the specified low-frequency ripple current rating of 134 mA @ 100 Hz. Selection depends on whether the application requires enhanced high-frequency ripple current handling.

Q: Are the substitute parts available in the same packaging format?

A: Yes. All three parts (PEG124MA2220QL1, PEG124MA2220QE4, and PEG124MA2220QT1) are supplied in axial, can package with identical physical dimensions of 0.394" diameter by 0.787" length (10.00 mm x 20.00 mm). Through-hole mounting configuration is identical across all parts.

Q: What is the significance of the product status difference (discontinued vs. active)?

A: The PEG124MA2220QL1 is discontinued at DiGi Electronics, meaning it is no longer available for new procurement through this distributor. The substitute parts PEG124MA2220QE4 and PEG124MA2220QT1 maintain active product status, ensuring continued availability for production and design support. Both substitutes are manufactured by KEMET and meet identical electrical specifications.

Q: Do the substitute parts maintain the same regulatory compliance?

A: Yes. Both PEG124MA2220QE4 and PEG124MA2220QT1 are ROHS3 compliant and REACH unaffected, matching the compliance status of the original PEG124MA2220QL1. All parts carry ECCN classification EAR99 and HTSUS code 8532.22.0020.

Q: Can inventory levels influence the selection between substitute parts?

A: Inventory availability may be a practical consideration. PEG124MA2220QE4 has 1998 pcs in stock, while PEG124MA2220QT1 has 1029 pcs in stock. For applications with no specific high-frequency ripple current requirements, PEG124MA2220QE4 offers greater availability. For applications requiring enhanced high-frequency performance, PEG124MA2220QT1 remains adequately stocked.
