TC10101 100µF 100V Axial Aluminum Electrolytic Capacitor Equivalent & Substitute Parts

Part Overview

The TC10101 is a 100 µF, 100 V aluminum electrolytic capacitor in axial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The TC series represents general-purpose applications requiring polar electrolytic capacitors with axial lead configuration and through-hole mounting.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC10101 is determined by strict equivalence in the following parameters:

Primary Matching Criteria:

• Capacitance: 100 µF (exact match required)
• Voltage Rating: 100 V (exact match required)
• Polarization: Polar (exact match required)
• Package/Case: Axial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)

Secondary Compatibility Parameters:

• Operating Temperature Range: Minimum -40°C to +85°C support
• Tolerance: ±20% acceptable (original part specifies -10%, +75%)
• ESR and Lifetime: May vary within application requirements

All three substitute parts (MAL202119101E3, MAL202190532E3, MAL212029101E3) meet the primary matching criteria. Differences in ESR, lifetime ratings, and physical dimensions are secondary considerations based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

MAL202119101E3 Selection Criteria: This substitute is suitable for general-purpose applications requiring extended lifetime at standard operating temperatures. The part is ROHS3 compliant and actively manufactured. ESR is higher than the original TC10101 (1.15 Ohm vs. 360 mOhm), which may impact performance in ripple-current-sensitive circuits. Physical dimensions are significantly smaller (10.00mm diameter vs. 19.05mm), requiring PCB layout verification.

MAL202190532E3 Selection Criteria: This substitute offers the most compact form factor (10.00mm diameter, 25.00mm length) among the three options. Lifetime rating is intermediate (2500 Hrs @ 85°C). ESR is 1.3 Ohm. ROHS3 compliant and actively manufactured. Suitable for space-constrained applications where lifetime requirements are moderate.

MAL212029101E3 Selection Criteria: This substitute is qualified to AEC-Q200 automotive standards and supports extended operating temperature range (-40°C to +125°C). ESR of 389 mOhm is closest to the original TC10101 specification. Lifetime rating is 8000 Hrs @ 125°C, providing superior reliability at elevated temperatures. ROHS3 compliant and actively manufactured. Recommended for automotive applications or designs requiring higher temperature operation.

All three substitutes are ROHS3 compliant, addressing environmental compliance requirements that the obsolete TC10101 does not meet.

Frequently Asked Questions (FAQ)

Q: Can MAL202119101E3, MAL202190532E3, and MAL212029101E3 be used interchangeably with TC10101?

A: All three parts meet the core electrical specifications (100 µF, 100 V, polar, axial, through-hole). However, physical dimensions differ significantly. PCB layout and mechanical clearance must be verified before substitution. ESR and lifetime characteristics also differ and should be evaluated against application requirements.

Q: What is the primary difference between the three substitute options?

A: MAL202119101E3 and MAL202190532E3 are from the 021 ASM series with general-purpose ratings. MAL212029101E3 is from the 120 ATC series with AEC-Q200 automotive qualification and extended temperature range (-40°C to +125°C). Physical dimensions vary across all three parts.

Q: Why is the ESR specification different between TC10101 and the substitutes?

A: ESR is measured at different frequencies (TC10101 at 120 Hz; substitutes at 10 kHz). ESR varies with frequency in electrolytic capacitors. Direct comparison requires measurement at identical frequencies. The substitutes generally exhibit higher ESR values, which may affect performance in high-ripple-current applications.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three substitute parts (MAL202119101E3, MAL202190532E3, MAL212029101E3) are ROHS3 compliant. The original TC10101 is RoHS non-compliant.

Q: Which substitute is best for automotive applications?

A: MAL212029101E3 is the recommended choice for automotive applications. It carries AEC-Q200 qualification, supports extended operating temperature range to +125°C, and provides 8000-hour lifetime at elevated temperature.

Q: Do the physical dimension differences affect circuit performance?

A: Physical dimensions affect PCB layout, mechanical clearance, and thermal dissipation characteristics. Electrical performance (capacitance, voltage rating, polarization) is not directly affected by size differences. However, ESR and ripple current handling may be influenced by package design and internal construction.

Q: What is the tolerance difference between TC10101 and the substitutes?

A: TC10101 specifies -10%, +75% tolerance. All three substitutes specify ±20% tolerance. The substitute tolerance is tighter and more symmetrical, providing better capacitance consistency.

Q: Can MAL202190532E3 be used in applications requiring 1000+ hour lifetime at 85°C?

A: MAL202190532E3 provides 2500 hours lifetime at 85°C, which exceeds the 1000-hour requirement of TC10101. For applications requiring 8000+ hours, MAL202119101E3 or MAL212029101E3 are more suitable.
