Key Parameters

Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Equivalence Parameters:

• Capacitance value (33 µF)
• Voltage rating (63 V minimum)
• Tolerance specification (-10%, +30%)
• ESR at rated frequency (2.2 Ohm @ 100 Hz)
• Thermal lifetime rating (2000 Hrs @ 125°C)
• Operating temperature range (-40°C ~ 125°C)
• Package configuration (Axial, Can)
• Mounting method (Through Hole)
• Physical dimensions (10.00mm x 29.00mm)
• Polarization type (Polar)

The identified substitute parts maintain full electrical and mechanical compatibility with the original PEG124MB2330QL1 specification. Substitutes are grouped by product status and availability, with distinction made for ripple current performance at high frequency where variations exist within the acceptable parameter set.

Engineering Selection Recommendations

PEG124MB2330QE4 (MFR Recommended Substitute)

The PEG124MB2330QE4 is the manufacturer-recommended substitute for the discontinued PEG124MB2330QL1. This part maintains full electrical equivalence across all critical parameters including capacitance, voltage rating, tolerance, ESR, thermal lifetime, and operating temperature range. The component is currently in active production status with 864 units in stock. Physical dimensions and mounting configuration are identical, ensuring direct mechanical compatibility in existing PCB layouts.

The PEG124MB2330QE4 exhibits reduced ripple current performance at high frequency (530 mA @ 5 kHz versus 1.4 A @ 5 kHz), which represents a design variation within the PEG124 series. This difference is acceptable for applications where high-frequency ripple current demand does not exceed 530 mA.

PEG124MB2330QT1 (Upgrade Substitute)

The PEG124MB2330QT1 provides full electrical and mechanical equivalence to the original part, including identical ripple current specifications at both low and high frequencies (1.4 A @ 5 kHz). This part is currently in active production status with 815 units in stock. The packaging designation is Bulk, indicating different distribution format compared to the original part. All electrical parameters, physical dimensions, and compliance certifications are identical to the PEG124MB2330QL1.

Both substitute parts carry ROHS3 compliance and REACH Unaffected status, maintaining regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can PEG124MB2330QE4 be used as a direct replacement for PEG124MB2330QL1?

A: Yes. The PEG124MB2330QE4 maintains electrical equivalence across all critical parameters: 33 µF capacitance, 63 V voltage rating, 2.2 Ohm ESR @ 100 Hz, 2000 Hrs @ 125°C lifetime, and identical physical dimensions (10.00mm x 29.00mm). The component is electrically and mechanically compatible for direct substitution in through-hole applications.

Q: What is the difference in ripple current between PEG124MB2330QE4 and PEG124MB2330QT1?

A: The PEG124MB2330QE4 is rated for 530 mA ripple current at 5 kHz, while the PEG124MB2330QT1 is rated for 1.4 A at 5 kHz. Both maintain 158 mA ripple current at 100 Hz. Selection between these parts depends on the high-frequency ripple current requirements of the application circuit.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts—PEG124MB2330QL1, PEG124MB2330QE4, and PEG124MB2330QT1—share identical physical dimensions of 0.394" diameter by 1.142" length (10.00mm x 29.00mm). They are all axial, can-type packages suitable for through-hole mounting on standard PCB layouts.

Q: What is the difference between the packaging designations?

A: The original PEG124MB2330QL1 and substitute PEG124MB2330QE4 do not specify a packaging designation in the provided data. The PEG124MB2330QT1 is designated as Bulk packaging, indicating a different distribution format. All three parts are functionally equivalent; packaging designation refers to order quantity and delivery format rather than component specifications.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All three parts—PEG124MB2330QL1, PEG124MB2330QE4, and PEG124MB2330QT1—are ROHS3 Compliant and REACH Unaffected, maintaining regulatory compliance across all jurisdictions.

Q: Which substitute part should be selected for new designs?

A: Both PEG124MB2330QE4 and PEG124MB2330QT1 are active production parts suitable for new designs. Selection is based on ripple current requirements: use PEG124MB2330QT1 if high-frequency ripple current must reach 1.4 A @ 5 kHz; use PEG124MB2330QE4 if ripple current requirements do not exceed 530 mA @ 5 kHz.
