T322F476K035AS Equivalent & Substitute Parts

Part Overview

The T322F476K035AS is a 47 µF molded tantalum capacitor manufactured by KEMET, rated for 35 V operation in an axial through-hole package. This component is classified as Active product status and serves general-purpose applications requiring stable capacitance in compact form factors. The primary reason for identifying substitute parts relates to RoHS compliance requirements and inventory availability across manufacturing batches, as the original part carries RoHS non-compliant status while functionally equivalent alternatives with improved compliance certifications are available.

Substitute Part Grouping Explanation

Substitution of the T322F476K035AS is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance Value: 47 µF (exact match required)
• Voltage Rating: 35 V (exact match required)
• Tolerance: ±10% (exact match required)
• ESR: 800 mOhm (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Package Type: Axial through-hole (exact match required)
• Physical Dimensions: 0.300" Dia x 0.710" L (exact match required)
• Series Classification: T322 (exact match required)

The substitute part T322F476K035AT meets all electrical and mechanical specifications identically to the main part. The primary distinction between these parts is the RoHS compliance status, where the substitute carries ROHS3 Compliant certification compared to the non-compliant status of the original part. Both parts maintain identical functional performance characteristics and are interchangeable from an electrical and mechanical standpoint.

Parameter Comparison

Engineering Selection Recommendations

T322F476K035AS is suitable for applications where RoHS compliance is not a regulatory requirement and existing inventory or legacy system specifications mandate the non-compliant variant.

T322F476K035AT is the preferred selection for new designs, production runs subject to RoHS3 compliance mandates, and applications requiring adherence to modern environmental and regulatory standards. This part maintains identical electrical performance and physical compatibility while providing enhanced compliance certification. Both parts carry Active product status, confirming ongoing manufacturer support and availability.

Selection between these parts should be based on compliance requirements of the end application and regulatory jurisdiction rather than electrical or mechanical performance considerations, as these parameters are fully equivalent.

Frequently Asked Questions (FAQ)

Q: Are T322F476K035AS and T322F476K035AT electrically interchangeable?

A: Yes. Both parts are electrically identical with matching capacitance (47 µF), voltage rating (35 V), tolerance (±10%), and ESR (800 mOhm). They operate across the same temperature range (-55°C to 125°C) and deliver identical performance in circuit applications.
