Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC50100 is based on the following electrical and mechanical parameters:

Primary Matching Criteria:

• Capacitance value: 1000 µF (exact match required)
• Polarization: Polar (electrolytic type maintained)
• Package type: Axial, Can (form factor compatibility)
• Mounting type: Through Hole (circuit board integration)
• Operating temperature range: -40°C ~ 85°C (functional envelope)

Secondary Compatibility Factors:

• Voltage rating: Substitute must equal or exceed the 50 V requirement
• Equivalent series resistance (ESR): Lower values indicate improved performance characteristics
• Lifetime rating: Extended operational hours at temperature indicate reliability

The MAL202118102E3 from Vishay Beyschlag/Draloric/BC Components satisfies all primary matching criteria with a higher voltage rating (63 V) and improved lifetime specification (8000 Hrs @ 85°C), making it suitable for direct substitution in applications where the TC50100 was originally specified.

Parameter Comparison

Engineering Selection Recommendations

The MAL202118102E3 is the qualified substitute for the TC50100 based on the following engineering factors:

Electrical Compatibility: Both components share identical capacitance values (1000 µF) and operate within the same temperature envelope (-40°C to 85°C). The MAL202118102E3 provides a higher voltage rating (63 V versus 50 V), which ensures adequate safety margin in applications originally designed for the TC50100.

Mechanical Compatibility: Both components utilize axial, can package configurations with through-hole mounting, ensuring direct circuit board integration without layout modifications.

Product Status and Compliance: The TC50100 is classified as obsolete, whereas the MAL202118102E3 maintains active product status with current manufacturing support. The MAL202118102E3 achieves ROHS3 compliance, addressing regulatory requirements for new designs and procurement cycles.

Reliability Characteristics: The MAL202118102E3 demonstrates an extended lifetime rating of 8000 hours at 85°C compared to the TC50100's 1000-hour specification, indicating improved long-term operational reliability.

Frequently Asked Questions (FAQ)

Q: Can the MAL202118102E3 be used as a direct replacement for the TC50100 in existing circuit designs?

A: Yes. Both components share identical capacitance (1000 µF), polarization (polar), package type (axial, can), and mounting configuration (through-hole). The MAL202118102E3 operates within the same temperature range and provides a higher voltage rating, ensuring functional compatibility.

Q: What is the significance of the voltage rating difference between the TC50100 (50 V) and MAL202118102E3 (63 V)?

A: The higher voltage rating of the MAL202118102E3 provides additional safety margin and does not negatively impact circuit performance. Capacitors rated for higher voltages can be used in applications specified for lower voltages without functional degradation.

Q: How do the ESR values differ between these components, and does this affect substitution?

A: The TC50100 specifies 80 mOhm @ 120 Hz, while the MAL202118102E3 specifies 135 mOhm. The higher ESR of the substitute may introduce marginally increased heat dissipation in high-ripple-current applications. For general-purpose applications, this difference is not operationally significant.

Q: What is the impact of the lifetime rating difference on component selection?

A: The MAL202118102E3 provides 8000 hours at 85°C compared to the TC50100's 1000-hour rating. This extended lifetime indicates improved reliability and longer operational service life, representing an enhancement over the original specification.

Q: Are there physical dimension differences that require circuit board layout modifications?

A: Yes. The TC50100 measures 0.875" diameter × 2.625" length, while the MAL202118102E3 measures 0.709" diameter × 1.181" length. The substitute component is physically smaller, which may allow for improved board layout efficiency but does not prevent substitution in existing designs.

Q: Does the tolerance difference between -10%, +75% (TC50100) and ±20% (MAL202118102E3) affect circuit performance?

A: The MAL202118102E3 provides tighter tolerance control (±20%) compared to the TC50100's asymmetrical tolerance. This represents an improvement in capacitance accuracy and consistency, benefiting circuit performance in applications sensitive to capacitance variation.

Q: What compliance advantages does the MAL202118102E3 offer?

A: The MAL202118102E3 achieves ROHS3 compliance, whereas the TC50100 is non-compliant. For new designs and procurement in regulated markets, the MAL202118102E3 satisfies environmental and regulatory requirements.
