PEG127KB3220QL1 Equivalent & Substitute Parts

Part Overview

The PEG127KB3220QL1 is a 220 µF, 40 V aluminum electrolytic capacitor in axial, can package manufactured by KEMET. This component is rated for automotive applications with AEC-Q200 compliance and operates across a temperature range of -40°C to 150°C. The part is currently discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain identical electrical and mechanical specifications for direct replacement in existing designs.

Substitute Part Grouping Explanation

Substitution of the PEG127KB3220QL1 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute parts identified maintain identical specifications in the following key areas:

Electrical Parameters:

• Capacitance: 220 µF (exact match required)
• Voltage Rating: 40 V (exact match required)
• ESR: 360 mOhm @ 100 Hz (exact match required)
• Lifetime: 1600 Hrs @ 150°C (exact match required)
• Operating Temperature: -40°C ~ 150°C (exact match required)
• Ripple Current specifications at both low and high frequencies (exact match required)
• Tolerance: -10%, +30% (exact match required)

Mechanical Parameters:

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

Compliance & Certification:

• AEC-Q200 automotive rating (exact match required)
• ROHS3 compliance (exact match required)
• Series: PEG127 (exact match required)

All identified substitutes meet these criteria and are therefore electrically and mechanically interchangeable with the original part.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts identified—PEG127KB3220QE4 and PEG127KB3220QT1—are direct electrical and mechanical equivalents to the discontinued PEG127KB3220QL1. Selection between these options is based on product availability and compliance status:

PEG127KB3220QE4 (MFR Recommended Substitute): This part is the manufacturer-recommended equivalent with active product status. It maintains all electrical specifications, dimensional requirements, and automotive AEC-Q200 certification. REACH compliance is confirmed. This part is suitable for direct replacement in all applications where the original PEG127KB3220QL1 was specified.

PEG127KB3220QT1 (Upgrade Option): This part is also an active product with confirmed ROHS3 compliance and REACH unaffected status. It is supplied in bulk packaging and maintains identical electrical and mechanical specifications. This part is suitable for direct replacement and offers the advantage of active product status with confirmed compliance documentation.

Both parts are interchangeable with the original component. Selection should be based on procurement requirements, packaging preferences, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can PEG127KB3220QE4 or PEG127KB3220QT1 be used as direct replacements for PEG127KB3220QL1?

A: Yes. Both substitute parts are direct replacements. They maintain identical capacitance (220 µF), voltage rating (40 V), ESR (360 mOhm @ 100 Hz), temperature ratings, ripple current specifications, physical dimensions (0.394" Dia x 1.142" L), and mounting configuration (through-hole axial, can package). All three parts are AEC-Q200 rated for automotive applications.

Q: What is the difference between PEG127KB3220QE4 and PEG127KB3220QT1?

A: Both parts are electrically and mechanically identical. The primary differences are product status (both active), packaging format (PEG127KB3220QT1 is supplied in bulk), and compliance documentation availability. PEG127KB3220QT1 has confirmed ROHS3 compliance explicitly stated in the data.

Q: Are there any dimensional differences between these parts?

A: No. All three parts share identical physical dimensions of 0.394" diameter by 1.142" length (10.00 mm x 29.00 mm). They are all through-hole mounted axial, can package components and are mechanically interchangeable.

Q: Do these substitute parts meet automotive specifications?

A: Yes. All three parts carry AEC-Q200 certification and are rated for automotive applications. Operating temperature range is -40°C to 150°C for all parts, with 1600 hours lifetime at 150°C.

Q: What is the tolerance specification for these capacitors?

A: All three parts have identical tolerance of -10%, +30% on the 220 µF capacitance value.

Q: Are there any compliance or regulatory differences between the original and substitute parts?

A: All parts are REACH Unaffected and classified as EAR99 for export control purposes. HTSUS code is identical (8532.22.0020). PEG127KB3220QL1 and PEG127KB3220QT1 both confirm ROHS3 compliance. PEG127KB3220QE4 does not have RoHS status explicitly stated in available data.

Q: What is the ripple current rating for these capacitors?

A: Both low and high frequency ripple current ratings are identical across all three parts: 1.19 A @ 100 Hz and 3.4 A @ 5 kHz.
