MAL212366159 Equivalent & Substitute Parts

Part Overview

The MAL212366159 is a 15 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 rated for general-purpose applications with an operating temperature range of -55°C to 125°C and a lifetime specification of 20,000 hours at 125°C. The part is currently obsolete, making identification of suitable substitute components necessary for ongoing system support and new production requirements.

Substitute Part Grouping Explanation

Substitution of the MAL212366159 is based on the following critical parameters:

• Capacitance Value: 15 µF (exact match required)
• Tolerance: ±20% (must match or be tighter)
• Package Type: Axial, Can through-hole configuration
• Polarization: Polar (required for functional compatibility)
• Voltage Rating: Minimum 25 V (equal or higher voltage rating acceptable)
• Physical Dimensions: Compatible with 0.264" Dia x 0.602" L footprint or smaller equivalent
• Mounting Type: Through-hole axial mount

The substitute part 156TTA050M meets these criteria with identical capacitance and tolerance, higher voltage rating (50 V), and compatible axial through-hole packaging. The substitute features a smaller physical footprint (0.197" Dia x 0.512" L), which is mechanically compatible with the original design space.

Parameter Comparison

Engineering Selection Recommendations

The 156TTA050M is an active production substitute for the obsolete MAL212366159. Selection of this substitute is based on the following engineering factors:

Electrical Compatibility: Both components share identical capacitance (15 µF) and tolerance (±20%). The substitute features a higher voltage rating (50 V vs. 25 V), which provides additional design margin and is functionally compatible with circuits designed for 25 V operation.

Product Status: The MAL212366159 is obsolete, while the 156TTA050M is in active production with confirmed inventory availability (3,596 pieces in stock).

Compliance: The 156TTA050M is ROHS3 compliant, whereas the original part is RoHS non-compliant. The substitute is REACH unaffected, compared to the original part's REACH affected status.

Physical Compatibility: The substitute features a smaller physical footprint (0.197" Dia x 0.512" L versus 0.264" Dia x 0.602" L), which is mechanically compatible with the original design space and may provide improved board layout flexibility.

Operating Conditions: The original part specifies -55°C to 125°C operation with 20,000 hours lifetime at 125°C. The substitute operates from -40°C to 85°C with 2,000 hours lifetime at 85°C. Applications requiring the full -55°C lower temperature limit or extended 125°C operation must evaluate thermal requirements against the substitute's specifications.

Frequently Asked Questions (FAQ)

Q: Can the 156TTA050M directly replace the MAL212366159 in all applications?

A: The 156TTA050M is electrically compatible for circuits designed around 25 V operation due to its higher 50 V rating. However, applications requiring operation below -40°C or sustained operation at 125°C must evaluate the substitute's temperature and lifetime specifications against system requirements.

Q: What are the key differences between these two capacitors?

A: The primary differences are voltage rating (50 V vs. 25 V), operating temperature range (-40°C to 85°C vs. -55°C to 125°C), lifetime specification (2,000 hours at 85°C vs. 20,000 hours at 125°C), physical size (smaller for the substitute), and product status (active vs. obsolete). Both maintain identical capacitance, tolerance, and axial through-hole packaging.

Q: Are there any compliance considerations when substituting this part?

A: Yes. The 156TTA050M is ROHS3 compliant and REACH unaffected, while the MAL212366159 is RoHS non-compliant and REACH affected. Systems requiring RoHS compliance should use the substitute.

Q: Will the smaller physical size of the 156TTA050M affect board layout?

A: The substitute's smaller footprint (0.197" Dia x 0.512" L) is mechanically compatible with the original design space. No board layout modifications are required, and the smaller size may provide additional routing flexibility.

Q: What is the impact of the different ESR values?

A: The 156TTA050M has lower ESR (13.2629 Ohm @ 120Hz) compared to the original (19 Ohm @ 100Hz). Lower ESR generally results in reduced heat generation and improved high-frequency performance, which is beneficial for most applications.

Q: How do the ripple current ratings compare?

A: The 156TTA050M supports 70 mA @ 120 Hz ripple current, compared to 60 mA @ 100 Hz for the original. The substitute provides higher ripple current capacity at the specified frequency.
