Key Parameters

Substitute Part Grouping Explanation

The 293D475X9050D2TE3 qualifies as a direct substitute based on the following critical electrical and mechanical parameters:

Matching Parameters:

• Capacitance: 4.7 µF (identical value)
• Voltage Rating: 50 V (identical rating)
• Package/Case: 2917 (7343 Metric) (identical footprint)
• Mounting Type: Surface Mount (identical mounting method)
• Moisture Sensitivity Level: 1 (Unlimited) (identical MSL classification)
• HTSUS Code: 8532.21.0050 (identical classification)
• ECCN: EAR99 (identical export classification)

The substitute maintains functional and mechanical interchangeability within the specified electrical operating envelope and PCB assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

Both TAJD475K050ESA and 293D475X9050D2TE3 maintain active product status and share identical electrical ratings (4.7 µF, 50 V) and mechanical footprints (2917/7343 Metric). The primary distinction exists in compliance classification: the KYOCERA AVX part carries RoHS non-compliant status with REACH Affected designation, while the Vishay Sprague substitute achieves ROHS3 compliance and REACH Unaffected status. Selection between these parts must account for system-level regulatory requirements and procurement specifications governing hazardous substance restrictions and international trade compliance.

Frequently Asked Questions (FAQ)

Q: Can the 293D475X9050D2TE3 be used as a direct replacement for TAJD475K050ESA in high-reliability applications?

A: Both parts match in capacitance (4.7 µF), voltage rating (50 V), and package footprint (2917/7343 Metric). Interchangeability is determined by design specifications regarding tolerance (293D475X9050D2TE3 specifies ±10%), ESR limits (1.2 Ω for the substitute), and operating temperature range (-55°C to 125°C for the substitute). Verify circuit-level requirements against the substitute's specified parameters.

Q: What is the primary difference in compliance between these two parts?

A: The KYOCERA AVX TAJD475K050ESA is RoHS non-compliant and REACH Affected, while the Vishay Sprague 293D475X9050D2TE3 is ROHS3 compliant and REACH Unaffected. Organizations operating under EU directives or customer specifications requiring RoHS and REACH compliance must select the Vishay Sprague substitute.

Q: Are the physical dimensions identical between both parts?

A: Both parts utilize the 2917 (7343 Metric) package with surface mount mounting type. The Vishay Sprague substitute specifies physical dimensions of 7.30mm × 4.30mm length and width, with maximum seated height of 3.10mm. PCB layout compatibility is maintained across both parts.

Q: How does moisture sensitivity level affect component selection?

A: Both parts carry MSL rating of 1 (Unlimited), indicating unrestricted shelf life and no moisture precautions required for storage, handling, or assembly. This classification removes moisture-related constraints from the substitution decision.

Q: What inventory considerations apply when sourcing between these alternatives?

A: The KYOCERA AVX TAJD475K050ESA maintains 1,038 units in current stock. The Vishay Sprague 293D475X9050D2TE3 has 1,605 units available. Procurement decisions may leverage inventory availability in conjunction with compliance and operational requirements.
