Engineering Selection Recommendations

PEG127MB2680QE4 (MFR Recommended Substitute)

The PEG127MB2680QE4 is the manufacturer-recommended equivalent for the discontinued PEG127MB2680QL1. This part maintains complete electrical and mechanical parity with the original component across all specified parameters. The part carries active product status with 1147 units in stock, ensuring supply continuity. AEC-Q200 compliance and REACH unaffected status confirm suitability for automotive applications. This substitute provides direct replacement capability without circuit redesign or board layout modification.

PEG127MB2680QT1 (Upgrade Substitute)

The PEG127MB2680QT1 functions as an equivalent substitute with identical electrical and mechanical specifications. This part is supplied in bulk packaging and maintains active product status with 673 units in stock. RoHS3 compliance and REACH unaffected status align with regulatory requirements. The upgrade designation reflects packaging format rather than functional enhancement, as all electrical parameters remain equivalent to the original component.

Both substitute parts are suitable for direct replacement in automotive circuits requiring 68 µF, 63 V aluminum electrolytic capacitors with axial, can package configuration and AEC-Q200 compliance.

Frequently Asked Questions (FAQ)

Q: Can PEG127MB2680QE4 and PEG127MB2680QT1 be used interchangeably with PEG127MB2680QL1?

A: Yes. Both substitute parts maintain identical electrical specifications (capacitance, voltage rating, ESR, ripple current, temperature range) and mechanical dimensions (0.394" Dia x 1.142" L). The parts differ only in product status and packaging designation, not in functional performance.

Q: What is the difference between the MFR Recommended and Upgrade substitutes?

A: The PEG127MB2680QE4 (MFR Recommended) and PEG127MB2680QT1 (Upgrade) are electrically and mechanically identical. The primary distinction is packaging format: PEG127MB2680QT1 is supplied in bulk packaging. Both are active products suitable for production use.

Q: Are the substitute parts compatible with existing PCB layouts?

A: Yes. Both substitute parts maintain the same axial, can package configuration with identical physical dimensions (10.00 mm diameter x 29.00 mm length) and through-hole mounting type. No PCB layout modification is required.

Q: Do the substitute parts maintain automotive compliance?

A: Yes. Both PEG127MB2680QE4 and PEG127MB2680QT1 carry AEC-Q200 ratings and are designated for automotive applications, matching the compliance profile of the original PEG127MB2680QL1.

Q: What is the inventory status of the substitute parts?

A: PEG127MB2680QE4 has 1147 units in stock. PEG127MB2680QT1 has 673 units in stock. Both parts maintain active product status, ensuring continued availability.

Q: Are there any differences in temperature performance between the main part and substitutes?

A: No. All three parts operate across the identical temperature range of -40°C to 150°C with a lifetime rating of 1600 hours at 150°C.

Q: Do the substitute parts meet RoHS and REACH requirements?

A: Both substitute parts maintain REACH unaffected status. PEG127MB2680QT1 is explicitly RoHS3 compliant. The PEG127MB2680QE4 RoHS status is not specified in available documentation but maintains equivalent compliance profile as an active KEMET automotive component.
