Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAJD477K006H is determined by strict equivalence across the following parameters:

• Capacitance Value: 470 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 6.3 V (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The substitute part 293D477X96R3D2TE3 (Vishay Sprague) meets all mandatory electrical and mechanical parameters. Variations in ESR (Equivalent Series Resistance) and RoHS compliance status do not disqualify substitution but are documented for engineering evaluation.

Parameter Comparison

Engineering Selection Recommendations

Both the TAJD477K006H and 293D477X96R3D2TE3 are Active status components suitable for direct substitution based on electrical and mechanical equivalence. The primary differentiation factor is RoHS compliance status: the Vishay Sprague 293D477X96R3D2TE3 is ROHS3 compliant, while the KYOCERA AVX TAJD477K006H is RoHS non-compliant. Selection should be based on regulatory requirements and end-application compliance mandates. The ESR difference of 100 mOhm between parts (400 mOhm vs. 500 mOhm) falls within acceptable operational variance for general purpose tantalum capacitor applications and does not constitute a functional limitation.

Frequently Asked Questions (FAQ)

Q: Can the 293D477X96R3D2TE3 be used as a direct replacement for the TAJD477K006H?

A: Yes. Both parts share identical capacitance (470 µF), tolerance (±10%), voltage rating (6.3 V), package (2917/7343 Metric), and operating temperature range (-55°C ~ 125°C). Physical dimensions and mounting characteristics are equivalent, enabling direct PCB substitution.

Q: What is the significance of the ESR difference between these parts?

A: The TAJD477K006H has 400 mOhm ESR while the 293D477X96R3D2TE3 has 500 mOhm ESR. This 100 mOhm variance is within normal manufacturing tolerance for molded tantalum capacitors and does not affect general purpose circuit performance. Applications with strict ESR requirements should specify the lower-ESR part.

Q: Does RoHS compliance affect substitution eligibility?

A: RoHS compliance is a regulatory and procurement consideration, not an electrical or mechanical substitution criterion. The ROHS3 compliant 293D477X96R3D2TE3 may be preferred for applications subject to RoHS directives, while the RoHS non-compliant TAJD477K006H remains functionally equivalent for non-regulated applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.287" L x 0.169" W (7.30mm x 4.30mm) with a maximum seated height of 0.122" (3.10mm). They are housed in the same 2917 (7343 Metric) package and are mechanically interchangeable on PCB layouts.

Q: What is the Moisture Sensitivity Level (MSL) for these capacitors?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special desiccant or humidity control requirements.
