TC80 Aluminum Electrolytic Capacitor - Equivalent & Substitute Parts

Part Overview

The TC80 is an 80 µF, 450 V aluminum electrolytic capacitor in axial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete product status. Identification of equivalent and substitute parts is necessary due to the discontinued nature of the original component, requiring alternative sourcing options that maintain functional compatibility within circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC80 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Capacitance: 80 µF (exact match required)
• Polarization: Polar (matching polarity orientation)
• Package / Case: Axial, Can (mechanical form factor)
• Mounting Type: Through Hole (installation method)

Performance Parameters Affecting Substitution:

• Voltage - Rated: Must equal or exceed 450 V
• Operating Temperature Range: Must encompass -40°C to 85°C
• ESR (Equivalent Series Resistance): Lower values indicate better performance
• Ripple Current Capability: Must support circuit ripple current demands

The substitute part WBR80-250A shares identical capacitance (80 µF), package type (axial, can), and mounting method (through hole). However, the rated voltage is reduced to 250 V, which restricts substitution to applications operating at or below 250 V. This voltage limitation is the primary constraint for direct interchangeability.

Parameter Comparison

Engineering Selection Recommendations

TC80 (Original Component) The TC80 is classified as obsolete. This part is suitable for applications requiring 450 V rating and the specified electrical performance characteristics.

WBR80-250A (Substitute Part) The WBR80-250A offers improved design characteristics: extended lifetime (2000 Hrs @ 85°C versus 1000 Hrs), RoHS3 compliance status, and reduced physical dimensions. The substitute is applicable only to circuits operating at or below 250 V. The higher tolerance range (-10%, +100%) and lower ripple current rating (200 mA @ 120 Hz versus 1.068 A) must be evaluated against specific circuit requirements. Both parts are obsolete in status.

Frequently Asked Questions (FAQ)

Q: Can WBR80-250A replace TC80 in any application? A: Substitution is permitted only when the circuit operates at 250 V or below. The TC80's 450 V rating cannot be downgraded to 250 V without circuit analysis. Direct replacement is not universally applicable across all TC80 installations.

Q: What are the physical dimension differences? A: The WBR80-250A is smaller: 0.740" diameter x 1.690" length compared to TC80's 1.000" diameter x 3.125" length. This dimensional reduction may affect board layout and thermal considerations in compact installations.

Q: How do the ripple current ratings affect substitution? A: The TC80 supports 1.068 A ripple current at 120 Hz, while WBR80-250A supports only 200 mA at 120 Hz. Applications requiring high ripple current capacity must retain the TC80 or source alternative substitutes with compatible ripple current specifications.

Q: What is the impact of RoHS compliance differences? A: TC80 is RoHS non-compliant, while WBR80-250A is ROHS3 compliant. Applications subject to RoHS regulatory requirements must use WBR80-250A or other compliant alternatives.

Q: Are the tolerance differences significant for circuit performance? A: TC80 specifies -10%, +50% tolerance; WBR80-250A specifies -10%, +100% tolerance. The wider tolerance of the substitute may affect circuit performance in applications with tight capacitance tolerances. Circuit tolerance analysis is required.
