T350G686K006AS Equivalent & Substitute Parts

Part Overview

The T350G686K006AS is a 68 µF conformal coated tantalum capacitor manufactured by KEMET, rated for 6.3 V operation in a radial through-hole package. This component belongs to the T350 UltraDip II series and is classified as active product status. The part is designed for general-purpose applications requiring stable capacitance performance across the operating temperature range of -55°C to 125°C. Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable or when design requirements mandate compliance with specific regulatory standards such as RoHS3.

Substitute Part Grouping Explanation

Substitution of the T350G686K006AS is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical capacitance (68 µF), voltage rating (6.3 V), tolerance (±10%), and ESR (1.8 Ohm) specifications. Physical compatibility requires matching mounting type (through hole), package configuration (radial), and dimensional specifications including diameter (0.248" / 6.30mm), maximum seated height (0.402" / 10.20mm), and lead spacing (0.100" / 2.54mm). The operating temperature range (-55°C to 125°C) and conformal coating type must be preserved. Parts are grouped as direct substitutes only when all these parameters align without deviation.

Parameter Comparison

Engineering Selection Recommendations

The T350G686K006AT serves as a direct electrical and mechanical substitute for the T350G686K006AS. Both parts are manufactured by KEMET within the same T350 UltraDip II series and maintain identical specifications for capacitance, voltage rating, tolerance, ESR, operating temperature range, and physical dimensions. The primary distinction between these parts is regulatory compliance status: the T350G686K006AS is RoHS non-compliant, while the T350G686K006AT is ROHS3 compliant. Selection between these parts should be based on applicable regulatory requirements in the target market or application. When RoHS3 compliance is mandated, the T350G686K006AT is the appropriate selection. When RoHS compliance is not a requirement, either part may be used interchangeably from an electrical and mechanical standpoint. Both parts maintain active product status and are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can T350G686K006AT be used as a direct replacement for T350G686K006AS in existing designs?

A: Yes. The T350G686K006AT is electrically and mechanically identical to the T350G686K006AS. All critical parameters including capacitance (68 µF), voltage rating (6.3 V), tolerance (±10%), ESR (1.8 Ohm), operating temperature range (-55°C to 125°C), and physical dimensions are identical. The parts are pin-compatible and footprint-compatible for through-hole radial mounting.

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

A: The primary difference is RoHS compliance status. The T350G686K006AS is RoHS non-compliant, while the T350G686K006AT is ROHS3 compliant. All other electrical, mechanical, and performance specifications are identical.

Q: Are there any performance differences between T350G686K006AS and T350G686K006AT?

A: No. Both parts deliver identical performance across all specified parameters: capacitance stability, ESR characteristics, voltage rating, temperature performance, and reliability. The RoHS3 compliance of the T350G686K006AT does not alter electrical or mechanical performance.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements applicable to your application and target market. If RoHS3 compliance is required, select T350G686K006AT. If RoHS compliance is not a requirement, either part may be selected based on availability and cost considerations.

Q: Are both parts available in production quantities?

A: Yes. The T350G686K006AS has 957 pieces in stock, and the T350G686K006AT has 1195 pieces in stock, both listed as new original inventory.

Q: Can I mix these parts in the same production batch?

A: Yes. From an electrical and mechanical standpoint, these parts are fully interchangeable. However, if RoHS compliance documentation is required for your application, ensure that all units in a batch meet the applicable compliance standard.

Q: What is the lead spacing for these radial capacitors?

A: The lead spacing is 0.100" (2.54mm) for both parts, which is standard for through-hole radial mounting on 0.1-inch pitch PCB layouts.

Q: What are the physical dimensions of these capacitors?

A: Both parts have a diameter of 0.248" (6.30mm) and a maximum seated height of 0.402" (10.20mm). These dimensions are critical for PCB layout and enclosure clearance planning.
