MALSECA00AG415BARK Equivalent & Substitute Parts

Part Overview

The MALSECA00AG415BARK is a 1500 µF, 6.3 V aluminum electrolytic capacitor manufactured by Vishay Beyschlag/Draloric/BC Components in the ECA series. This component is rated for general-purpose applications with a 2000-hour lifetime at 85°C and features surface mount radial can packaging. The part is currently obsolete, making identification of equivalent substitutes necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for aluminum electrolytic capacitors is determined by the following parameters:

• Capacitance value must match exactly: 1500 µF
• Voltage rating must equal or exceed the original: 6.3 V minimum
• Tolerance must be compatible: ±20%
• Package and mounting type must be identical: Surface mount radial can
• Case diameter must match: 10.00 mm
• ESR must be within acceptable operational limits for the application
• Polarization must remain polar

The substitute part 158AXZ6R3M meets all these criteria while offering improved thermal performance and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The 158AXZ6R3M is a direct functional substitute for the MALSECA00AG415BARK. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute part offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• Equivalent ESR performance (309 mOhm vs. 310 mOhm) maintains electrical characteristics
• Extended operating temperature range (-55°C ~ 105°C vs. -40°C ~ 85°C) provides greater thermal margin
• Improved lifetime rating at elevated temperature (2000 Hrs @ 105°C vs. 2000 Hrs @ 85°C)

The substitute part has a maximum case height of 11.00 mm compared to 10.50 mm for the original. PCB layout verification is required to confirm clearance compatibility. The surface mount land size differs slightly (10.00 mm x 10.00 mm vs. 10.30 mm x 10.30 mm), requiring pad adjustment during board redesign.

Frequently Asked Questions (FAQ)

Q: Can the 158AXZ6R3M be used as a direct drop-in replacement?

A: Electrical compatibility is confirmed. Physical compatibility requires verification of PCB clearance due to the 0.50 mm increase in case height and adjustment of surface mount land dimensions.

Q: What is the significance of the different operating temperature ranges?

A: The substitute part operates from -55°C to 105°C compared to the original -40°C to 85°C. This extended range provides greater design margin for applications subject to temperature extremes, though the original design specifications should be the limiting factor.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.

Q: Why does the substitute part have different surface mount land dimensions?

A: The 158AXZ6R3M uses 10.00 mm x 10.00 mm land pads versus 10.30 mm x 10.30 mm for the original. PCB artwork must be updated to accommodate the smaller footprint during redesign.

Q: Is the ripple current specification important for substitution?

A: The original part specifies 480 mA @ 120 Hz ripple current. The substitute part specifies 425 mA @ 120 Hz. Application ripple current requirements must not exceed 425 mA at 120 Hz to ensure reliable operation.
