T356K686K016AS Equivalent & Substitute Parts

Part Overview

The T356K686K016AS is a 68 µF conformal coated tantalum capacitor manufactured by KEMET, rated for 16 V operation in a radial through-hole package. This component belongs to the T356 UltraDip II series and is classified as a general-purpose capacitor with an equivalent series resistance (ESR) of 1 Ohm. The part is currently active in production with 796 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, design revisions, or compliance requirements.

Substitute Part Grouping Explanation

Substitution of the T356K686K016AS is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical capacitance (68 µF), voltage rating (16 V), tolerance (±10%), ESR (1 Ohm), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (radial), and physical dimensions (0.350" diameter, 0.610" height, 0.200" lead spacing). The substitute part must also belong to the same T356 UltraDip II series and be classified as a general-purpose conformal coated tantalum capacitor. Substitution is permitted when these parameters are identical across both components.

Parameter Comparison

Engineering Selection Recommendations

The T356K686K016AT serves as a direct electrical and mechanical substitute for the T356K686K016AS. Both components are manufactured by KEMET and share identical specifications across all critical parameters including capacitance, voltage rating, tolerance, ESR, operating temperature range, and physical dimensions. The primary distinction between these parts is compliance status: the T356K686K016AS is RoHS non-compliant, while the T356K686K016AT is ROHS3 compliant. Selection between these parts should be based on the regulatory and compliance requirements of the end application. For applications requiring ROHS3 compliance, the T356K686K016AT is the appropriate selection. For applications without RoHS compliance mandates, either part is electrically and mechanically interchangeable. Both parts are currently in active production with adequate inventory levels.

Frequently Asked Questions (FAQ)

Q: Are the T356K686K016AS and T356K686K016AT electrically identical?

A: Yes. Both parts have identical capacitance (68 µF), voltage rating (16 V), tolerance (±10%), ESR (1 Ohm), and operating temperature range (-55°C to 125°C). They are electrically equivalent for all circuit applications.

Q: Can these parts be used interchangeably on a printed circuit board?

A: Yes. Both parts share identical physical dimensions (0.350" diameter, 0.610" height), lead spacing (0.200"), and radial through-hole mounting configuration. They are mechanically interchangeable without PCB redesign.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The T356K686K016AS is RoHS non-compliant, while the T356K686K016AT is ROHS3 compliant. All other specifications are identical.

Q: Which part should I select for a new design?

A: Selection depends on regulatory requirements. If ROHS3 compliance is required, select T356K686K016AT. If RoHS compliance is not a requirement, either part is suitable based on availability.

Q: Are both parts currently available?

A: Yes. The T356K686K016AS has 796 units in stock, and the T356K686K016AT has 775 units in stock.

Q: Do these parts have the same temperature operating range?

A: Yes. Both parts operate across the identical temperature range of -55°C to 125°C.

Q: Can I substitute one part for the other in existing inventory?

A: Yes, provided the application does not have specific RoHS compliance mandates. The parts are electrically and mechanically equivalent.
