TC493 Equivalent & Substitute Parts

Part Overview

The TC493 is a 100 µF, 150 V aluminum electrolytic capacitor in axial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete and is used in general-purpose applications requiring through-hole mounting. The TC493 operates across a temperature range of -40°C to 85°C with a rated lifetime of 1000 hours at 85°C. Due to its obsolete status, equivalent substitute parts with active product status and improved performance characteristics are available to maintain design continuity and ensure long-term component availability.

Substitute Part Grouping Explanation

Substitution of the TC493 is based on electrical and mechanical parameter equivalence. The primary substitution criteria are:

Electrical Parameters:

• Capacitance value: 100 µF (exact match required)
• Voltage rating: 150 V (minimum, equal or higher acceptable)
• Polarization: Polar (must match)

Mechanical Parameters:

• Package type: Axial, Can (must match)
• Mounting type: Through Hole (must match)
• Physical dimensions: 0.750" Dia x 1.625" L (must match for board compatibility)

Performance Parameters:

• Operating temperature range must encompass or exceed the original specification
• Ripple current ratings at specified frequencies must meet or exceed original values

The substitute part 601D107F150GJ7 satisfies all mandatory electrical and mechanical equivalence criteria and provides enhanced performance characteristics including extended lifetime rating and improved ESR specifications.

Engineering Selection Recommendations

The 601D107F150GJ7 manufactured by Vishay Sprague is a direct functional substitute for the obsolete TC493. Selection of this substitute part is supported by the following engineering factors:

Product Status: The TC493 is classified as obsolete, creating supply chain risk. The 601D107F150GJ7 maintains active product status, ensuring continued availability and manufacturing support.

Electrical Equivalence: Both parts share identical capacitance (100 µF) and voltage rating (150 V) specifications. The substitute part provides tighter capacitance tolerance (-10%, +50% versus -10%, +75%), which represents an improvement in performance consistency.

Mechanical Compatibility: Physical dimensions, package type (Axial, Can), and through-hole mounting configuration are identical between both parts, enabling direct board-level substitution without layout modifications.

Performance Enhancement: The 601D107F150GJ7 provides extended operational lifetime (2000 hours at 105°C versus 1000 hours at 85°C) and an expanded operating temperature range (-55°C to 105°C versus -40°C to 85°C), supporting applications with more demanding thermal requirements.

Compliance: Both parts carry identical ECCN (EAR99) and HTSUS (8532.22.0040) classifications, maintaining regulatory consistency in supply chain documentation.
