Substitute Part Grouping Explanation

Substitution of the PEG124UB1470QL1 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 4.7 µF (exact match)
• Voltage rating: 350 V (exact match)
• ESR @ 100 Hz: 17 Ohm (exact match)
• Lifetime @ temperature: 5000 Hrs @ 105°C (exact match)
• Operating temperature range: -40°C ~ 105°C (exact match)
• Tolerance: -10%, +30% (exact match)

Mechanical Equivalence Requirements:

• Package type: Axial, Can (exact match)
• Mounting type: Through Hole (exact match)
• Physical dimensions: 0.394" Dia x 1.142" L / 10.00 mm x 29.00 mm (exact match)
• Polarization: Polar (exact match)

Compliance Requirements:

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99

Substitute parts identified within the PEG124 series maintain all electrical and mechanical parameters while differing only in product status, packaging configuration, or ripple current performance at specific frequencies. Parts with identical ripple current specifications at both 100 Hz and 5 kHz provide direct functional replacement. Parts with reduced ripple current at 5 kHz remain electrically equivalent but may require thermal analysis in high-frequency ripple current applications.

Engineering Selection Recommendations

PEG124UB1470QE4 Selection Criteria: The PEG124UB1470QE4 maintains full electrical and mechanical equivalence to the PEG124UB1470QL1 across all critical parameters. This part is currently active in production status with confirmed inventory availability. The ripple current specification at 5 kHz is reduced to 140 mA compared to the original 370 mA specification. Selection of this part is appropriate for applications where high-frequency ripple current demands do not exceed 140 mA at 5 kHz. Both parts carry identical RoHS3 compliance and REACH unaffected status.

PEG124UB1470QT1 Selection Criteria: The PEG124UB1470QT1 provides direct functional replacement with identical electrical specifications, including ripple current performance at both 100 Hz (55 mA) and 5 kHz (370 mA). This part is currently active in production status with confirmed inventory availability. The packaging configuration is specified as Bulk. This part is suitable for applications requiring full performance equivalence to the original PEG124UB1470QL1 specification, including high-frequency ripple current handling. Both parts carry identical RoHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can PEG124UB1470QE4 be used as a direct replacement for PEG124UB1470QL1?

A: The PEG124UB1470QE4 is electrically and mechanically equivalent across all core parameters including capacitance, voltage rating, ESR, lifetime, and operating temperature range. The ripple current specification at 5 kHz differs (140 mA versus 370 mA). Direct replacement is appropriate for applications where the 5 kHz ripple current requirement does not exceed 140 mA.

Q: What is the difference between PEG124UB1470QE4 and PEG124UB1470QT1?

A: Both parts are electrically equivalent to the original PEG124UB1470QL1 across capacitance, voltage, ESR, and lifetime specifications. The primary difference is ripple current performance at 5 kHz: PEG124UB1470QE4 is rated for 140 mA while PEG124UB1470QT1 is rated for 370 mA. The PEG124UB1470QT1 provides full specification equivalence including high-frequency ripple current performance.

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

A: Yes. All three parts share identical physical dimensions of 0.394" diameter by 1.142" length (10.00 mm x 29.00 mm). All are axial, can package configuration with through-hole mounting. PCB layout and mechanical fit are identical.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. PEG124UB1470QE4 and PEG124UB1470QT1 are both ROHS3 compliant and REACH unaffected, matching the compliance status of the original PEG124UB1470QL1. Both carry identical ECCN (EAR99) and HTSUS classifications.

Q: What is the significance of the product status difference?

A: The original PEG124UB1470QL1 is discontinued at DiGi Electronics, indicating no further availability through standard distribution channels. Both substitute parts (PEG124UB1470QE4 and PEG124UB1470QT1) are active in production status with confirmed current inventory, ensuring ongoing availability for new designs and replacement applications.

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

A: Selection between PEG124UB1470QE4 and PEG124UB1470QT1 depends on high-frequency ripple current requirements. For applications requiring 370 mA ripple current handling at 5 kHz, select PEG124UB1470QT1. For applications with ripple current demands not exceeding 140 mA at 5 kHz, either part is suitable; PEG124UB1470QE4 may be selected based on availability or packaging preference.
