Cornell Dubilier 159LBA016M2BF Equivalent & Substitute Parts

Part Overview

The Cornell Dubilier 159LBA016M2BF is a 15000 µF, 16 V aluminum electrolytic capacitor with radial, can-mount snap-in configuration. This Active product is designed for general-purpose applications requiring high capacitance and low equivalent series resistance in standard through-hole packaging. Substitute parts are necessary to address inventory availability, operational temperature requirements, voltage rating enhancements, or performance characteristics across different manufacturing sources while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 159LBA016M2BF is determined by the following critical parameters:

• Capacitance: 15000 µF (exact match required)
• Voltage Rating: 16 V minimum (equal or higher voltage ratings are acceptable)
• Package Configuration: Radial, Can - Snap-In with identical lead spacing (0.394" / 10.00mm) and mounting footprint
• Physical Dimensions: Diameter 0.866" (22.00mm) and height 1.654" (42.00mm) maximum
• Mounting Type: Through Hole only
• Polarization: Polar

The listed substitute parts meet all mechanical compatibility requirements and maintain the same capacitance value and rated voltage (or higher). Variations in ESR, ripple current handling, and maximum operating temperature represent performance enhancements or different thermal characteristics that do not prevent functional substitution.

Parameter Comparison

Engineering Selection Recommendations

All three capacitors maintain Active product status with full ROHS3 compliance and REACH Unaffected designation, ensuring regulatory compatibility across industrial and commercial applications.

B41252A4159M (EPCOS - TDK Electronics) provides a direct functional equivalent with matching 16 V voltage rating. This substitute offers extended maximum operating temperature to 105°C versus the original 85°C rating, providing improved thermal margin in elevated-temperature environments.

MAL225626153E3 (Vishay) supplies a voltage-rated upgrade to 25 V while maintaining identical capacitance and physical form factor. The enhanced voltage rating provides additional design margin for transient overvoltage conditions. The measured ESR of 40 mOhm represents improved performance compared to the original 55.26 mOhm specification, reducing thermal dissipation in high ripple-current applications.

Both substitutes are mechanically and electrically compatible drop-in replacements that share identical mounting footprints, lead spacing, and package configurations with the original Cornell Dubilier component.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 159LBA016M2BF with either of these parts without PCB modifications?

A: Yes. Both substitute parts maintain identical mechanical specifications: 0.394" lead spacing, 0.866" case diameter, and 1.654" maximum height. No PCB layout changes are required for either replacement.

Q: What is the voltage compatibility between the original and substitutes?

A: The original 159LBA016M2BF and the B41252A4159M are both rated 16 V. The MAL225626153E3 is rated 25 V, which is suitable for any 16 V application and provides additional safety margin against overvoltage transients.

Q: Why do the substitute parts show different ESR and ripple current values?

A: ESR and ripple current ratings vary between manufacturers due to different design architectures and material formulations. The MAL225626153E3 demonstrates lower ESR (40 mOhm versus 55.26 mOhm), which reduces heat generation in applications with significant AC ripple current.

Q: Are there temperature differences I should consider?

A: The original 159LBA016M2BF operates to 85°C with a 2000-hour lifetime at that temperature. Both substitutes extend the maximum operating range to 105°C with 2000-hour lifetime ratings at 105°C, offering improved thermal performance in higher-temperature environments.

Q: Do all three parts have identical package types?

A: Yes. All three capacitors use Radial, Can - Snap-In configuration with through-hole mounting, maintaining full mechanical and electrical interchangeability on standard PCB footprints.
