MAL212314681E3 Equivalent & Substitute Parts

Part Overview

The MAL212314681E3 is a 680 µF, 10 V aluminum electrolytic capacitor in axial configuration, manufactured by Vishay Beyschlag/Draloric/BC Components as part of the SAL-A 123 series. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity. The axial, can-style package with through-hole mounting is commonly used in general-purpose applications requiring stable capacitance and extended operational life.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAL212314681E3 is determined by the following critical parameters:

Primary Substitution Criteria:

• Capacitance value: 680 µF (exact match required)
• Tolerance: ±20% (standard for aluminum electrolytic capacitors)
• Package type: Axial, Can configuration
• Mounting: Through-hole technology
• Operating temperature range: -55°C ~ 125°C minimum
• Voltage rating: Equal to or greater than 10 V

Secondary Compatibility Factors:

• ESR and impedance characteristics within acceptable operational limits
• Physical dimensions compatible with PCB layout constraints
• RoHS3 compliance for regulatory alignment

The substitute part MAL211815681E3 maintains identical capacitance, tolerance, temperature range, and package configuration while offering an increased voltage rating of 16 V, making it suitable for applications where the original 10 V specification is no longer available.

Engineering Selection Recommendations

The MAL211815681E3 serves as the primary substitute for the obsolete MAL212314681E3 based on the following engineering factors:

Compliance and Availability: The substitute part maintains ROHS3 compliance and is classified as active product status, ensuring continued availability and regulatory alignment for new designs and production runs.

Electrical Compatibility: Both components share identical capacitance (680 µF) and tolerance (±20%), with matching operating temperature ranges (-55°C ~ 125°C). The substitute's higher voltage rating (16 V versus 10 V) provides additional design margin and is backward-compatible with 10 V circuit specifications.

Physical Considerations: The substitute features a smaller physical footprint (0.394" Dia x 1.181" L versus 0.508" Dia x 1.260" L), which may require PCB layout verification to confirm compatibility with existing through-hole mounting patterns and spacing requirements.

Performance Trade-offs: The substitute exhibits higher ESR (525 mOhm versus 250 mOhm) and impedance (450 mOhms versus 200 mOhms), along with reduced lifetime at temperature (8000 Hrs @ 125°C versus 20000 Hrs @ 125°C). These characteristics remain within acceptable parameters for general-purpose applications but should be evaluated for ripple current and thermal stress conditions specific to the target circuit.

Frequently Asked Questions (FAQ)

Q: Can MAL211815681E3 directly replace MAL212314681E3 in existing designs?

A: Yes, the substitute maintains the same capacitance value, tolerance, and operating temperature range. However, verify PCB layout compatibility due to the smaller physical dimensions and confirm that the higher ESR and impedance values are acceptable for your specific circuit requirements.

Q: What is the significance of the voltage rating difference (10 V versus 16 V)?

A: The substitute's higher voltage rating provides additional safety margin and is fully compatible with circuits designed for 10 V operation. No circuit modifications are required; the component will function reliably at or below its rated voltage.

Q: How do the ESR and impedance differences affect circuit performance?

A: The substitute's higher ESR (525 mOhm) and impedance (450 mOhms) may result in slightly increased voltage ripple and heat generation under high-frequency ripple current conditions. Evaluate these parameters against your circuit's ripple current specifications and thermal constraints.

Q: Are there any compliance or regulatory concerns with this substitution?

A: Both components are ROHS3 compliant and REACH unaffected. No regulatory barriers exist for substitution in applications requiring these certifications.

Q: What should be verified before implementing this substitute in production?

A: Confirm PCB mounting hole spacing compatibility with the smaller axial can dimensions, validate ESR and impedance performance under actual circuit operating conditions, and verify thermal performance if the application involves sustained high-temperature operation.
