Equivalent & Substitute Parts for T356F476K006AS

Part Overview

The T356F476K006AS is a 47 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 T356 UltraDip II series and is classified as active product status. The part is designed for general-purpose applications requiring reliable energy storage in compact form factors with conformal coating protection.

Substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance, ESR) and mechanical compatibility (package type, mounting configuration, physical dimensions). The primary distinction between equivalent parts in this category relates to manufacturing compliance certifications and inventory availability.

Substitute Part Grouping Explanation

Substitution eligibility for the T356F476K006AS is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 47 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• Tolerance: ±10% (exact match required)
• ESR: 2 Ohm (exact match required)
• Conformal coating type (exact match required)

Mechanical Equivalence Criteria:

• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Physical dimensions: 0.236" diameter, 0.441" maximum height, 0.200" lead spacing (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)

Parts meeting all criteria above are classified as direct substitutes. The T356F476K006AT satisfies all electrical and mechanical parameters and is therefore a valid equivalent part.

Engineering Selection Recommendations

T356F476K006AS (Original Part):

• Product status: Active
• RoHS compliance: Non-compliant
• Current inventory: 946 pieces
• Selection basis: Use when RoHS non-compliance is acceptable for the application or when legacy system compatibility is required

T356F476K006AT (Substitute Part):

• Product status: Active
• RoHS compliance: ROHS3 Compliant
• Current inventory: 2487 pieces
• Selection basis: Use for new designs or applications requiring RoHS3 compliance. Higher inventory availability supports supply chain continuity

Both parts are electrically and mechanically identical. The primary differentiation factor is regulatory compliance status. Selection between these parts should be based on project requirements regarding RoHS compliance and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can T356F476K006AT be used as a direct replacement for T356F476K006AS on existing PCBs?

A: Yes. Both parts are identical in electrical performance (47 µF, 6.3 V, ±10%, 2 Ohm ESR), physical dimensions (0.236" diameter, 0.441" height, 0.200" lead spacing), and mounting configuration (radial through-hole). No PCB redesign or layout modification is required.

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

A: The parts are functionally equivalent. The primary difference is RoHS compliance status: T356F476K006AS is RoHS non-compliant, while T356F476K006AT is ROHS3 compliant. Both operate identically across the -55°C to 125°C temperature range.

Q: Are there any performance differences in ESR or operating temperature?

A: No. Both parts specify 2 Ohm ESR and identical operating temperature range (-55°C to 125°C). Electrical performance is equivalent.

Q: Which part should be selected for new product designs?

A: T356F476K006AT is recommended for new designs due to ROHS3 compliance, which aligns with current regulatory requirements and supply chain standards. This part also has higher current inventory availability (2487 pieces versus 946 pieces).

Q: Can these parts be mixed in the same production batch?

A: Yes, from an electrical and mechanical standpoint. However, design documentation and bill of materials should specify a single part number to maintain consistency and traceability.
