TC50200 Aluminum Electrolytic Capacitor - Equivalent & Substitute Parts

Part Overview

The TC50200 is a 2000 µF, 50 V aluminum electrolytic capacitor in axial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, indicating discontinued production and limited availability for new designs. 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 moderate capacitance and voltage ratings.

Due to obsolete status and finite inventory, identifying equivalent substitute parts is necessary for design continuity, procurement reliability, and long-term supply chain management. Substitute parts must maintain functional equivalence in capacitance, voltage rating, and physical form factor while meeting modern compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC50200 is evaluated based on the following criteria derived from the provided parameters:

Mandatory Matching Criteria:

• Capacitance value: 2000 µF (exact match required)
• Package type: Axial, Can (mechanical and electrical form factor)
• Mounting type: Through Hole (PCB assembly compatibility)
• Polarization: Polar (circuit polarity requirements)

Acceptable Variation Criteria:

• Voltage rating: Substitute must be ≥ 50 V (higher voltage ratings are acceptable and provide design margin)
• Operating temperature range: Substitute may exceed the original range; minimum operating temperature may be lower, maximum may be higher
• ESR and ripple current: Substitute values may differ; lower ESR is generally acceptable
• Lifetime at temperature: Substitute may exceed original specification
• Physical dimensions: Substitute may be smaller; larger dimensions require PCB layout verification
• Compliance standards: Modern substitutes may include RoHS3 compliance and REACH compliance

The substitute part B41689A7208Q001 meets the mandatory matching criteria with acceptable variations in voltage rating (40 V vs. 50 V rated), physical dimensions (smaller package), and enhanced reliability specifications.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The B41689A7208Q001 is a functional substitute for the TC50200 based on matching capacitance (2000 µF), package type (Axial, Can), and mounting configuration (Through Hole). The substitute is in active production status, ensuring supply chain continuity compared to the obsolete TC50200.

Critical Consideration - Voltage Rating:

The substitute part is rated at 40 V versus the original 50 V rating. This represents a 20% reduction in voltage headroom. Substitution is permissible only if the circuit's maximum operating voltage does not exceed 40 V. If the circuit is designed to operate at voltages between 40 V and 50 V, the substitute is not suitable without circuit redesign.

Compliance Advantage:

The B41689A7208Q001 is RoHS3 compliant, whereas the TC50200 is non-compliant. For new designs or products subject to RoHS regulations, the substitute provides regulatory compliance. Both parts are REACH Unaffected.

Reliability and Thermal Performance:

The substitute offers superior reliability specifications: 10,000 hours at 125°C versus 1,000 hours at 85°C for the original. The extended operating temperature range (-55°C to 125°C) provides greater thermal margin. These characteristics support long-term design reliability.

Physical Form Factor:

The substitute is physically smaller (21.00mm diameter × 39.00mm length versus 25.40mm × 66.68mm). Verify that the reduced dimensions accommodate the PCB layout and mechanical clearances of the target application.

Ripple Current Capability:

The substitute supports higher ripple current (8 A @ 10 kHz versus 3.93 A @ 2.4 kHz), indicating improved performance in high-frequency switching applications.

Frequently Asked Questions (FAQ)

Q: Can the B41689A7208Q001 directly replace the TC50200 in all applications?

A: Direct replacement is possible only if the circuit maximum voltage does not exceed 40 V. The substitute is rated at 40 V, which is 10 V lower than the original 50 V rating. Verify the circuit's voltage specifications before substitution.

Q: What is the significance of the different ESR values (70 mOhm vs. 165 mOhm)?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat dissipation. The substitute has higher ESR but is rated for higher ripple current (8 A vs. 3.93 A), indicating improved overall ripple current capability despite the higher ESR value. The reference frequencies differ (120 Hz vs. 100 Hz), making direct comparison complex; however, the substitute's higher ripple current rating at 10 kHz demonstrates superior high-frequency performance.

Q: Does the smaller physical size of the substitute create compatibility issues?

A: The substitute is physically smaller (21.00mm × 39.00mm versus 25.40mm × 66.68mm). This reduction in size is generally advantageous for PCB space constraints. However, verify that the smaller dimensions do not create mechanical clearance issues with adjacent components or mounting hardware. The axial lead spacing and through-hole mounting remain compatible.

Q: Is the substitute suitable for automotive applications?

A: The B41689A7208Q001 is specified for automotive applications. The TC50200 is designated for general-purpose use. If the target application is automotive, the substitute provides appropriate qualification and reliability specifications for that environment.

Q: What is the impact of the RoHS3 compliance difference?

A: The TC50200 is RoHS non-compliant; the B41689A7208Q001 is RoHS3 compliant. For products subject to RoHS regulations (primarily in EU markets and regulated industries), the substitute ensures regulatory compliance. For applications without RoHS requirements, this difference is not a technical constraint.

Q: Can the substitute handle the same operating temperature range as the original?

A: The substitute exceeds the original temperature range. The TC50200 operates from -40°C to 85°C; the B41689A7208Q001 operates from -55°C to 125°C. The substitute is suitable for applications within the original temperature range and extends capability to lower and higher temperatures if required.

Q: What is the tolerance difference between the two parts?

A: The TC50200 has a tolerance of -10%, +75%; the B41689A7208Q001 has -10%, +30%. The substitute has a tighter upper tolerance, meaning capacitance values will be more closely controlled around the nominal 2000 µF specification. This is generally advantageous for circuit performance consistency.

Q: Is the longer lifetime specification of the substitute (10,000 hrs vs. 1,000 hrs) a practical advantage?

A: Yes. The substitute's 10,000-hour lifetime at 125°C indicates significantly improved reliability and longevity. This specification supports extended product life and reduced field failure risk, particularly in applications with continuous or high-duty-cycle operation.
