MALSECV00AG415BARK Equivalent & Substitute Parts

Part Overview

The MALSECV00AG415BARK is a 1500 µF, 6.3 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Vishay Beyschlag/Draloric/BC Components. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. The part serves general-purpose applications requiring stable capacitance and low equivalent series resistance in compact SMD form factors.

Substitute Part Grouping Explanation

Substitution eligibility for the MALSECV00AG415BARK is determined by the following core parameters:

Capacitance value: 1500 µF (exact match required)
Voltage rating: 6.3 V (exact match required)
Tolerance: ±20% (exact match required)
Package type: Radial, Can - SMD (exact match required)
Mounting type: Surface Mount (exact match required)
Polarization: Polar (exact match required)

Engineering Selection Recommendations

The 158AXZ6R3M from Cornell Dubilier / Illinois Capacitor is a qualified substitute for the obsolete MALSECV00AG415BARK. Selection is supported by the following factors:

Both parts maintain identical capacitance (1500 µF), voltage rating (6.3 V), and tolerance (±20%)
Both comply with ROHS3 regulations and carry identical moisture sensitivity levels (MSL 1 - Unlimited)
The substitute part is in active production status, ensuring long-term availability and supply chain continuity
Physical package dimensions are compatible with minor height variation (0.02" difference) that does not typically impact PCB layout constraints
ESR specification of the substitute (309 mOhm @ 120Hz) remains within acceptable operational parameters for general-purpose applications
Extended operating temperature range (-55°C to 105°C) of the substitute provides additional thermal margin compared to the original part

Frequently Asked Questions (FAQ)

Q: Can the 158AXZ6R3M be used as a direct replacement for MALSECV00AG415BARK?

A: Yes. Both parts share identical capacitance, voltage rating, tolerance, package type, and RoHS compliance. The substitute is electrically and mechanically compatible for general-purpose applications.

Q: What is the significance of the ESR difference (250 mOhm vs. 309 mOhm)?

A: The ESR difference of 59 mOhm represents a 23.6% increase. For general-purpose bypass and decoupling applications, this variation remains within acceptable engineering tolerances. Applications requiring precise ESR specifications should be evaluated against actual circuit requirements.

Q: Does the height difference (0.413" vs. 0.433") affect PCB compatibility?

A: The 0.02" (0.5mm) height increase of the substitute part is minimal and typically does not impact PCB layout or component clearance in standard designs. Verify clearance in space-constrained applications.

Q: Why is the substitute part's operating temperature range wider (-55°C to 105°C vs. -40°C to 105°C)?

A: The substitute part maintains performance across a broader lower temperature range. This provides additional design margin and does not create compatibility issues when replacing the original part.

Q: Are the surface mount land patterns identical?

A: Land patterns differ slightly (0.406" x 0.406" vs. 0.394" x 0.394"). Both patterns are standard for 10mm diameter SMD cans. Verify PCB footprint compatibility with your design specifications before implementation.

Q: What is the inventory status of these parts?

A: MALSECV00AG415BARK: 965 Pcs in stock (obsolete status). 158AXZ6R3M: 881 Pcs in stock (active production). The substitute ensures continued availability despite the original part's obsolescence.
