Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAL212386689E3 is determined by the following critical parameters:

• Capacitance Value: Must remain 68 µF to maintain circuit functionality
• Polarization: Must be polar to match the original design
• Package Configuration: Must be axial, can type with through-hole mounting
• Voltage Rating: Must be equal to or greater than 25 V
• Tolerance: ±20% tolerance is acceptable
• Temperature Range: Must support -55°C to 125°C operation
• RoHS Compliance: ROHS3 compliance required for regulatory alignment

The substitute part MAL211819689E3 meets all substitution criteria while offering improved electrical characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The MAL211819689E3 serves as a direct functional substitute for the obsolete MAL212386689E3. Both components maintain identical capacitance values, tolerance specifications, and operating temperature ranges. The substitute part carries active product status, ensuring long-term availability and supply chain continuity.

The substitute exhibits a higher voltage rating (100 V versus 25 V), which provides additional design margin in applications where the original 25 V specification is sufficient. The lower ESR value (1.8 Ohm versus 4.1 Ohm) indicates improved high-frequency performance characteristics.

Both parts maintain ROHS3 compliance and are suitable for through-hole PCB assembly. The axial, can package configuration remains consistent between the main part and substitute, supporting direct mechanical and electrical compatibility in existing designs.

Frequently Asked Questions (FAQ)

Q: Can MAL211819689E3 replace MAL212386689E3 in all applications?

A: Yes, provided the circuit design operates at or below 25 V. The substitute's 100 V rating exceeds the original specification and does not create compatibility issues in circuits designed for 25 V operation.

Q: Are there physical dimension differences between these parts?

A: Yes. The main part measures 0.370" diameter × 0.917" length (9.40 mm × 23.30 mm). The substitute measures 0.492" diameter × 1.181" length (12.50 mm × 30.00 mm). PCB layout and mechanical clearance must be verified before substitution.

Q: What is the impact of the lower ESR in the substitute part?

A: Lower ESR (1.8 Ohm versus 4.1 Ohm) reduces impedance and improves performance at higher frequencies. This change is beneficial in most applications and does not create compatibility concerns.

Q: Does the substitute part meet the same compliance requirements?

A: Yes. Both the main part and substitute are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment for industrial and commercial applications.

Q: Why does the substitute have a lower lifetime rating at 125°C?

A: The substitute specifies 8,000 hours at 125°C compared to 20,000 hours for the main part. Application requirements for thermal endurance must be evaluated against this specification.
