MAL212366151 Equivalent & Substitute Parts

Part Overview

The MAL212366151 is a 150 µF, 25 V aluminum electrolytic capacitor in axial configuration, manufactured by Vishay Beyschlag/Draloric/BC Components as part of the 123 SAL-A series. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and component procurement.

The primary reason for identifying alternatives is the obsolete status of this part number, which limits availability for new production runs and maintenance applications. Substitute parts must maintain electrical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAL212366151 is based on the following critical parameters that must be maintained or exceeded:

Mandatory Compatibility Parameters:

• Capacitance value: 150 µF (exact match required)
• Tolerance: ±20% (matching tolerance class)
• Polarization: Polar (axial electrolytic configuration)
• Mounting type: Through Hole (axial lead configuration)
• Operating temperature range: -55°C ~ 125°C minimum

Allowable Parameter Variations:

• Voltage rating: May be equal to or greater than 25 V (higher voltage ratings provide backward compatibility in 25 V applications)
• ESR: Lower values are acceptable (improved performance characteristic)
• Lifetime: Lower values are acceptable in non-critical applications; higher values preferred
• Ripple current: Higher values indicate improved capability
• Physical dimensions: Minor variations acceptable if PCB layout permits

The substitute part MAL211818151E3 maintains the core electrical specifications while offering improved performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The MAL211818151E3 serves as a direct functional substitute for the MAL212366151 based on the following engineering criteria:

Electrical Compatibility: Both parts share identical capacitance (150 µF) and tolerance (±20%), with matching operating temperature ranges (-55°C ~ 125°C). The substitute's 63 V rating exceeds the original 25 V specification, providing voltage margin in the application circuit.

Performance Characteristics: The substitute exhibits lower ESR (1 Ohm versus 2.1 Ohm), resulting in reduced power dissipation and improved high-frequency performance. Impedance values are nearly equivalent (790 mOhms versus 800 mOhms).

Compliance Status: The MAL211818151E3 is ROHS3 compliant and carries active product status, ensuring long-term availability and compliance with current regulatory requirements. The original part is RoHS non-compliant and obsolete.

Physical Considerations: Dimensional differences exist (0.492" Dia x 1.181" L versus 0.406" Dia x 1.260" L). PCB layout verification is required to confirm that the substitute's slightly larger diameter and shorter length accommodate existing mounting holes and clearances.

Frequently Asked Questions (FAQ)

Q: Can MAL211818151E3 directly replace MAL212366151 in a 25 V circuit?

A: Yes. The substitute's 63 V rating provides overvoltage margin in applications designed for 25 V operation. The identical capacitance and tolerance ensure electrical equivalence.

Q: What are the key differences between these parts?

A: Primary differences include voltage rating (25 V versus 63 V), ESR (2.1 Ohm versus 1 Ohm), lifetime rating (20000 Hrs versus 8000 Hrs), physical dimensions, and compliance status (obsolete versus active, RoHS non-compliant versus ROHS3 compliant).

Q: Are there physical fitment concerns?

A: The substitute has a larger diameter (0.492" versus 0.406") and shorter length (1.181" versus 1.260"). PCB layout must be verified to ensure the substitute fits within existing mounting hole spacing and clearance requirements.

Q: Why is the substitute's lifetime rating lower?

A: The MAL211818151E3 is rated for 8000 Hrs at 125°C compared to 20000 Hrs for the original part. This difference reflects different design specifications within the respective product series. Application requirements determine whether this reduction is acceptable.

Q: Is the substitute suitable for automotive applications?

A: The MAL211818151E3 is specified for automotive applications. The original MAL212366151 is designated for general purpose use. Automotive-grade compliance may be a consideration depending on end-use requirements.

Q: What compliance certifications apply to the substitute?

A: The MAL211818151E3 is ROHS3 compliant and REACH unaffected. The original part is RoHS non-compliant and REACH affected. Both carry EAR99 ECCN classification and 8532.22.0020 HTSUS code.
