TC10102 Aluminum Electrolytic Capacitor - Equivalent & Substitute Parts

Part Overview

The TC10102 is a 1000 µF, 100 V aluminum electrolytic capacitor in axial configuration manufactured by Cornell Dubilier Electronics (CDE). This component is designed for general-purpose applications requiring polarized capacitive energy storage and filtering. The part is classified as obsolete, making identification of functionally equivalent substitutes necessary for ongoing system support and procurement planning. The TC series represents legacy capacitor technology with specific electrical characteristics that must be matched during component replacement.

Substitute Part Grouping Explanation

Substitution of the TC10102 is based on strict electrical and mechanical parameter matching within the aluminum electrolytic capacitor category. The following criteria determine valid substitutes:

Primary Matching Criteria:

• Capacitance value: 1000 µF (exact match required)
• Voltage rating: 100 V (substitute must equal or exceed)
• Polarization: Polar (required for circuit compatibility)
• Package type: Axial, Can (physical form factor)
• Mounting method: Through Hole (assembly compatibility)
• Operating temperature range: -40°C ~ 85°C (environmental compatibility)

Secondary Electrical Parameters:

• ESR and ripple current ratings determine performance under load conditions
• Lifetime specification indicates expected service duration under rated conditions
• Tolerance specification affects circuit accuracy requirements

The MAL202119102E3 from Vishay Beyschlag/Draloric/BC Components satisfies all primary matching criteria and maintains electrical compatibility within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TC10102 is classified as obsolete. The MAL202119102E3 is classified as active, ensuring continued availability and manufacturing support.

Compliance Status: The TC10102 is RoHS non-compliant. The MAL202119102E3 is ROHS3 compliant, meeting current regulatory requirements for new designs and procurement in regulated markets.

Electrical Performance: Both components meet the core electrical requirements: 1000 µF capacitance at 100 V with identical operating temperature ranges. The MAL202119102E3 demonstrates superior reliability with 8000-hour lifetime at 85°C compared to 1000 hours for the TC10102. The higher ESR of the Vishay component (160 mOhm versus 80 mOhm) is within acceptable parameters for general-purpose applications but should be evaluated in ripple-current-sensitive circuits.

Physical Compatibility: The MAL202119102E3 is physically smaller (21.00mm diameter × 38.00mm length versus 25.40mm × 98.43mm), which may require PCB layout verification to confirm fit within existing mounting holes and clearance requirements.

Procurement Status: The MAL202119102E3 has 1202 units in stock (active inventory), while TC10102 stock is limited to 902 units (obsolete status).

Frequently Asked Questions (FAQ)

Q: Can the MAL202119102E3 be used as a direct replacement for the TC10102?

A: The MAL202119102E3 is electrically compatible as a substitute. Both components share identical capacitance (1000 µF), voltage rating (100 V), polarization, package type (axial can), mounting method (through hole), and operating temperature range (-40°C to 85°C). Physical dimensions differ; verify PCB mounting hole compatibility before installation.

Q: What is the impact of the higher ESR in the MAL202119102E3?

A: The MAL202119102E3 has 160 mOhm ESR compared to 80 mOhm for the TC10102. In general-purpose applications, this difference is acceptable. In circuits with high ripple current requirements or strict thermal constraints, the higher ESR may result in increased heat generation. Evaluate ripple current specifications for your specific application.

Q: Does the smaller physical size of the MAL202119102E3 affect installation?

A: The MAL202119102E3 is significantly smaller (21.00mm diameter × 38.00mm length versus 25.40mm × 98.43mm). Verify that existing PCB mounting holes and component clearances accommodate the smaller form factor. The through-hole mounting method remains identical.

Q: Why is the MAL202119102E3 rated for 8000 hours while the TC10102 is rated for 1000 hours?

A: Lifetime ratings reflect expected component longevity under specified conditions (85°C). The MAL202119102E3 demonstrates superior long-term reliability. This difference reflects advances in capacitor technology and manufacturing processes between the legacy TC series and current Vishay production.

Q: Is the MAL202119102E3 suitable for new designs?

A: Yes. The MAL202119102E3 is active-status, ROHS3 compliant, and meets current regulatory requirements. It is appropriate for new product development and procurement planning.

Q: What tolerance difference exists between these components?

A: The TC10102 has -10%, +75% tolerance; the MAL202119102E3 has ±20% tolerance. The Vishay component offers tighter tolerance control, which may be beneficial in precision applications requiring stable capacitance values.
