MAL214636331E3 Equivalent & Substitute Parts

Part Overview

The MAL214636331E3 is a 330 µF, 25 V aluminum electrolytic capacitor in radial configuration, manufactured by Vishay Beyschlag/Draloric/BC Components as part of the 146 RTI series. This component is designed for through-hole mounting applications requiring stable capacitance performance across automotive-grade operating conditions. The part is actively produced and maintains AEC-Q200 automotive qualification with a rated lifetime of 2500 hours at 125°C. Substitute parts are identified to provide equivalent electrical performance and mechanical compatibility for applications where the original part number may be unavailable or where alternative packaging formats are acceptable.

Substitute Part Grouping Explanation

Substitution of the MAL214636331E3 is based on strict equivalence of the following electrical and mechanical parameters:

Capacitance value: 330 µF (exact match required)
Voltage rating: 25 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package configuration: Radial, Can through-hole (exact match required)
Lead spacing: 0.197" (5.00 mm) (exact match required)
Case diameter: 0.394" (10.00 mm) (exact match required)
Height: 0.531" (13.50 mm) maximum (exact match required)
Operating temperature range: -55°C to 125°C (exact match required)
Lifetime rating: 2500 Hrs @ 125°C (exact match required)
Ripple current capability: 620 mA @ 100 kHz (exact match required)
Impedance: 120 mOhms (exact match required)
Automotive qualification: AEC-Q200 (exact match required)
Series designation: 146 RTI (exact match required)

The identified substitute differs only in packaging format (Bulk versus Tape & Box), which does not affect electrical performance or mechanical compatibility in the application.

Engineering Selection Recommendations

Both the MAL214636331E3 and MAL214656331E3 are active production parts from Vishay Beyschlag/Draloric/BC Components with identical electrical specifications and mechanical dimensions. Both components carry AEC-Q200 automotive qualification and are ROHS3 compliant. The parts are electrically and mechanically interchangeable in all applications requiring a 330 µF, 25 V radial aluminum electrolytic capacitor with through-hole mounting.

The sole distinction between these part numbers is the packaging format: MAL214636331E3 is supplied in Tape & Box format, while MAL214656331E3 is supplied in Bulk format. This difference affects only the delivery and handling method and does not impact component performance, reliability, or circuit compatibility.

Selection between these parts should be based on procurement requirements, inventory management practices, and supply chain availability rather than technical performance criteria.

Frequently Asked Questions (FAQ)

Q: Are MAL214636331E3 and MAL214656331E3 electrically identical?

A: Yes. Both parts have identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), operating temperature range (-55°C to 125°C), lifetime rating (2500 Hrs @ 125°C), ripple current capability (620 mA @ 100 kHz), and impedance (120 mOhms).

Q: Can these parts be used interchangeably on a PCB?

A: Yes. Both parts have identical mechanical dimensions, lead spacing (0.197" / 5.00 mm), case diameter (0.394" / 10.00 mm), and height (0.531" / 13.50 mm maximum). They mount identically in through-hole applications.

Q: What is the difference between Tape & Box and Bulk packaging?

A: Tape & Box packaging provides components on tape reels within protective boxes, suitable for automated assembly processes. Bulk packaging provides loose components in larger quantities. Both formats contain the same component with identical specifications.

Q: Do both parts meet automotive standards?

A: Yes. Both MAL214636331E3 and MAL214656331E3 carry AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: Which part should I select for my application?

A: Selection depends on your procurement and assembly requirements. If your manufacturing process uses automated pick-and-place equipment, Tape & Box format (MAL214636331E3) may be preferred. If you require bulk quantities for manual assembly or rework, Bulk format (MAL214656331E3) may be more suitable. Both parts deliver identical electrical and mechanical performance.
