Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC50150 is based on maintaining electrical compatibility within allowed parameter margins for aluminum electrolytic capacitors in axial, can configuration. The primary substitution criteria are:

• Capacitance Value: Must be 1500 µF to ensure circuit functionality
• Voltage Rating: Must be equal to or greater than 50 V to ensure safe operation
• Package Type: Must be axial, can format for mechanical compatibility with through-hole mounting
• Operating Temperature Range: Must encompass at minimum the -40°C to 85°C specification
• Polarization: Must maintain polar configuration

The MAL202118152E3 (Vishay Beyschlag/Draloric/BC Components) satisfies these core requirements while offering enhanced specifications in several areas.

Parameter Comparison

Engineering Selection Recommendations

The MAL202118152E3 is suitable as a direct substitute for the TC50150 based on the following engineering factors:

Electrical Compatibility: Both components feature identical capacitance values (1500 µF) and both operate within the -40°C to 85°C temperature range. The MAL202118152E3 provides a higher voltage rating (63 V vs. 50 V), which is permissible in substitution applications.

Product Status: The TC50150 is obsolete, while the MAL202118152E3 is active and currently stocked with 1863 pieces available. This status difference makes the MAL202118152E3 the practical choice for new applications and ongoing inventory replenishment.

Regulatory Compliance: The MAL202118152E3 is ROHS3 compliant, whereas the TC50150 is RoHS non-compliant. Organizations operating under RoHS regulatory requirements will benefit from this substitution.

Package and Mounting: Both components utilize identical through-hole, axial can configurations, ensuring mechanical compatibility with existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the MAL202118152E3 be used directly in place of the TC50150 without circuit modifications?

A: Yes, the MAL202118152E3 can be used as a direct substitute. Both components share the same capacitance value (1500 µF), operating temperature range (-40°C to 85°C), and package configuration (axial, can, through-hole). The higher voltage rating of the substitute (63 V vs. 50 V) does not present a compatibility issue.

Q: What are the physical dimension differences between these components?

A: The TC50150 measures 1.000" Dia x 2.625" L (25.40mm x 66.68mm). The MAL202118152E3 measures 0.709" Dia x 1.496" L (18.00mm x 38.00mm). The substitute is physically smaller in both diameter and length. Verify that your PCB layout and available mounting space can accommodate the smaller dimensions of the MAL202118152E3.

Q: Does the higher ESR of the MAL202118152E3 affect circuit performance?

A: The MAL202118152E3 has an ESR of 122 mOhm compared to 70 mOhm for the TC50150. This difference should be evaluated against your specific circuit requirements, particularly in applications sensitive to impedance characteristics at operating frequencies.

Q: What is the advantage of the longer lifetime specification of the MAL202118152E3?

A: The MAL202118152E3 is rated for 8000 hours at 85°C, compared to 1000 hours for the TC50150. This extended lifetime specification indicates improved reliability and longer functional service life in thermal stress conditions.

Q: Are there any tolerance differences to consider?

A: The TC50150 has a tolerance of -10%, +75%, while the MAL202118152E3 has a tighter tolerance of ±20%. The substitute's tighter tolerance may provide more predictable capacitance values in critical circuit applications.
