Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PEG124MB247VQL1 is determined by the following critical parameters:

Core Electrical Parameters (Non-Negotiable):

• Capacitance: 47 µF
• Voltage Rating: 63 V
• Tolerance: -10%, +30%
• Operating Temperature Range: -40°C to 125°C
• Lifetime: 2000 Hrs @ 125°C

Physical Parameters (Non-Negotiable):

• Package Type: Axial, Can
• Mounting Type: Through Hole
• Size: 0.394" Dia x 1.142" L (10.00mm x 29.00mm)

Compliance Parameters:

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99

Substitute parts must match all core electrical and physical parameters. ESR specifications and ripple current ratings are secondary differentiators used for performance optimization but do not disqualify substitution when core parameters align. Product status (Active vs. Discontinued) determines availability for procurement.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: PEG124MB247VQE4

The PEG124MB247VQE4 is the manufacturer-recommended equivalent. All core electrical parameters (47 µF, 63 V, -10%/+30% tolerance, 2000 Hrs @ 125°C, -40°C to 125°C operating range) and physical specifications (10.00mm x 29.00mm axial can, through-hole mounting) are identical to the main part. This part carries Active product status and maintains ROHS3 compliance. The ESR specification is not provided for this variant, but this does not affect functional equivalence when core parameters match. Current inventory: 639 pcs.

Secondary Substitutes: PEG124MB2470QE4 and PEG124MB2470QT1

Both upgrade parts provide identical core electrical and physical parameters with the addition of specified ESR (1.6 Ohm @ 100Hz) and ripple current ratings. The PEG124MB2470QE4 specifies 190 mA @ 100 Hz and 570 mA @ 5 kHz ripple current capability. The PEG124MB2470QT1 specifies 190 mA @ 100 Hz and 1.6 A @ 5 kHz ripple current capability, offering enhanced high-frequency ripple current performance. Both parts are Active status with ROHS3 compliance. Current inventory: 769 pcs (QE4) and 1021 pcs (QT1).

All three substitute parts are fully compatible with the discontinued PEG124MB247VQL1 for direct replacement in through-hole PCB applications requiring 47 µF, 63 V aluminum electrolytic capacitor functionality.

Frequently Asked Questions (FAQ)

Q: Can PEG124MB247VQE4 directly replace PEG124MB247VQL1?

A: Yes. Both parts share identical capacitance (47 µF), voltage rating (63 V), tolerance (-10%, +30%), lifetime (2000 Hrs @ 125°C), operating temperature range (-40°C to 125°C), and physical dimensions (10.00mm x 29.00mm axial can). The PEG124MB247VQE4 is the manufacturer-recommended equivalent and carries Active product status.

Q: What is the difference between the three substitute parts?

A: All three substitutes meet the core electrical and physical requirements. The primary difference is ESR and ripple current specification availability. PEG124MB247VQE4 does not specify ESR or ripple current. PEG124MB2470QE4 specifies 1.6 Ohm ESR @ 100Hz with 190 mA @ 100 Hz and 570 mA @ 5 kHz ripple current. PEG124MB2470QT1 specifies 1.6 Ohm ESR @ 100Hz with 190 mA @ 100 Hz and 1.6 A @ 5 kHz ripple current, providing superior high-frequency ripple current handling.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts (PEG124MB247VQE4, PEG124MB2470QE4, and PEG124MB2470QT1) are ROHS3 compliant and REACH unaffected, matching the compliance status of the original PEG124MB247VQL1.

Q: Can these parts be used in new designs or only as replacements?

A: These parts are suitable for both replacement applications and new designs. The Active product status of all three substitutes ensures long-term availability for ongoing procurement and design implementation.

Q: Does package type differ between the main part and substitutes?

A: No. All parts use identical axial, can package configuration with through-hole mounting. Physical dimensions are 0.394" diameter x 1.142" length (10.00mm x 29.00mm), ensuring mechanical compatibility with existing PCB layouts.

Q: Which substitute should be selected for high-ripple-current applications?

A: PEG124MB2470QT1 provides the highest specified ripple current at 5 kHz (1.6 A), compared to PEG124MB2470QE4 (570 mA @ 5 kHz). Selection depends on application ripple current requirements at operating frequency.
