TC75202 Aluminum Electrolytic Capacitor - Equivalent & Substitute Parts

Part Overview

The TC75202 is a 2000 µF, 75 V aluminum electrolytic capacitor in axial configuration manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, indicating discontinued production and limited availability in the market. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 1000 hours at 85°C, suitable for general-purpose applications requiring stable capacitance and moderate ripple current handling.

Due to its obsolete status, identifying functionally equivalent substitute components is essential for design continuity, system maintenance, and procurement planning. Substitutes must maintain compatibility with the original circuit requirements while considering differences in electrical performance characteristics and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the TC75202 is based on the following critical parameters:

Capacitance Match: The substitute must provide 2000 µF capacitance to maintain circuit functionality and frequency response characteristics.

Voltage Rating Compatibility: The original part is rated at 75 V. Substitutes operating at lower voltage ratings (such as 40 V) are not electrically equivalent and cannot be used in circuits designed for 75 V operation. A substitute at 40 V would violate voltage derating requirements and create reliability risks.

Package and Mounting Consistency: Both the main part and substitute must be axial, can-type aluminum electrolytic capacitors with through-hole mounting to ensure physical compatibility with existing PCB designs.

Polarization: Both components must maintain polar configuration to preserve circuit polarity requirements.

Operating Temperature Range: The substitute must support the -40°C to 85°C operating window or a superset thereof to ensure functionality across all specified environmental conditions.

Electrical Performance: ESR, ripple current ratings, and lifetime specifications influence thermal stability and long-term reliability but do not prevent substitution if the substitute meets minimum performance thresholds.

Based on these criteria, the identified substitute B41689A7208Q001 presents a voltage rating incompatibility (40 V versus 75 V), which disqualifies it as a direct electrical equivalent for circuits requiring the full 75 V rating of the original TC75202.

Parameter Comparison

Engineering Selection Recommendations

Voltage Rating Constraint: The B41689A7208Q001 operates at a maximum rated voltage of 40 V, which is 35 V below the TC75202 specification of 75 V. This represents a fundamental electrical incompatibility. Circuits designed for 75 V operation cannot safely use a 40 V-rated component without violating voltage derating margins and creating unacceptable reliability risk.

Compliance and Production Status: The TC75202 is obsolete and non-RoHS compliant, whereas the B41689A7208Q001 is in active production and ROHS3 compliant. From a procurement and regulatory perspective, the substitute offers advantages in availability and modern environmental compliance standards.

Thermal and Lifetime Performance: The B41689A7208Q001 provides superior lifetime rating (10000 hours at 125°C versus 1000 hours at 85°C) and operates across a wider temperature range (-55°C to 125°C). These characteristics indicate enhanced reliability under extended operating conditions.

Physical and Functional Compatibility: Both components share identical capacitance (2000 µF), polarization (polar), package type (axial can), and mounting method (through hole), ensuring mechanical and circuit board compatibility.

Substitution Verdict: The B41689A7208Q001 cannot serve as a direct substitute for the TC75202 in applications requiring the full 75 V rating. However, for applications where the actual operating voltage is 40 V or lower, and where the circuit design permits voltage derating, the B41689A7208Q001 may be considered as an alternative component with improved compliance and reliability characteristics. Circuit voltage requirements must be verified before any substitution decision.

Frequently Asked Questions (FAQ)

Q: Can the B41689A7208Q001 replace the TC75202 in my circuit?

A: Only if your circuit operates at 40 V or lower. The B41689A7208Q001 is rated for a maximum of 40 V, while the TC75202 is rated for 75 V. Using a lower-voltage-rated capacitor in a higher-voltage circuit violates electrical safety margins and creates failure risk. Verify your actual circuit operating voltage before substitution.

Q: What is the primary difference between these two capacitors?

A: The critical difference is voltage rating: TC75202 is 75 V, while B41689A7208Q001 is 40 V. Both share the same 2000 µF capacitance and axial can package. The substitute offers better compliance (ROHS3), longer lifetime (10000 hours), and wider temperature range (-55°C to 125°C).

Q: Will the physical dimensions cause installation problems?

A: The B41689A7208Q001 is physically smaller (21.00mm diameter × 39.00mm length) compared to the TC75202 (25.40mm diameter × 66.68mm length). While both are through-hole axial components, the smaller size of the substitute may require PCB layout verification to ensure proper fit in the original mounting holes and clearance around adjacent components.

Q: Is the B41689A7208Q001 more reliable than the TC75202?

A: The B41689A7208Q001 demonstrates superior reliability metrics: 10000-hour lifetime at 125°C versus 1000 hours at 85°C for the TC75202. The substitute also operates across a wider temperature range (-55°C to 125°C). However, reliability is application-dependent and must be evaluated within your specific circuit operating conditions.

Q: Why is the TC75202 obsolete?

A: The TC75202 is listed as obsolete, indicating Cornell Dubilier Electronics has discontinued production. Obsolescence typically results from market consolidation, technology evolution, or manufacturer portfolio rationalization. Active alternatives like the B41689A7208Q001 from EPCOS - TDK Electronics are available for new designs and maintenance applications.

Q: Can I use the B41689A7208Q001 in a 75 V circuit if I derate it?

A: No. Derating involves operating a component below its rated maximum, not above it. The B41689A7208Q001 has a maximum rating of 40 V; it cannot be safely operated at 75 V regardless of derating practices. Operating above rated voltage voids reliability guarantees and creates immediate failure risk.

Q: What should I do if I need a 2000 µF, 75 V axial capacitor?

A: Contact your component distributor to identify active production alternatives rated at 75 V or higher with 2000 µF capacitance and axial can package. The B41689A7208Q001 does not meet this voltage requirement. Verify that any substitute meets your circuit's voltage, temperature, and ripple current specifications.
