Substitute Part Grouping Explanation

Substitution eligibility for the 594D475X0050C8T is determined by strict equivalence across the following critical parameters:

• Capacitance value: 4.7 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 50 V (exact match required)
• Type: Conformal Coated tantalum (exact match required)
• ESR: 800 mOhm (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Package / Case: 2812 (7132 Metric) (exact match required)
• Physical dimensions: 0.280" L × 0.126" W (exact match required)
• Mounting type: Surface Mount (exact match required)
• Manufacturer size code: C (exact match required)
• MSL rating: 2A (4 Weeks) (exact match required)

The 594D475X0050C2T qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. Packaging format differences (Tape & Reel vs. Cut Tape & Digi-Reel®) do not affect component performance or circuit functionality.

Parameter Comparison

Engineering Selection Recommendations

Both the 594D475X0050C8T and 594D475X0050C2T are active production components from Vishay Sprague with identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

The 594D475X0050C2T offers ROHS3 compliance, whereas the 594D475X0050C8T is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 594D475X0050C2T is the appropriate selection.

Packaging format differs between the two parts. The 594D475X0050C8T is supplied in Tape & Reel (TR) format, while the 594D475X0050C2T is available in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on assembly equipment compatibility and procurement volume requirements.

Inventory availability differs, with the 594D475X0050C2T currently stocked at higher quantities (2268 pieces) compared to the 594D475X0050C8T (800 pieces).

Physical height specifications are equivalent within manufacturing tolerance, with the 594D475X0050C2T seated height measured at 2.79 mm versus 2.80 mm for the 594D475X0050C8T.

Frequently Asked Questions (FAQ)

Q: Can the 594D475X0050C2T be used as a direct replacement for the 594D475X0050C8T in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters including capacitance, voltage rating, ESR, operating temperature range, package dimensions, and mounting type. The parts are interchangeable at the circuit level.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Packaging format affects component delivery and handling during assembly. Tape & Reel (TR) is continuous reel packaging suitable for high-speed automated pick-and-place equipment. Cut Tape (CT) & Digi-Reel® provides flexibility for lower-volume or mixed-component assembly operations. Component performance is unaffected by packaging format.

Q: Does the RoHS compliance difference between these parts affect circuit performance?

A: No. RoHS compliance status reflects manufacturing process and material composition standards but does not alter electrical or mechanical performance. Selection based on RoHS compliance is a regulatory and supply chain consideration, not a technical performance factor.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both parts conform to the 2812 (7132 Metric) package specification with dimensions of 0.280" L × 0.126" W (7.10 mm × 3.20 mm). Seated height specifications are equivalent within manufacturing tolerance (2.80 mm vs. 2.79 mm).

Q: What does MSL 2A (4 Weeks) mean for component handling?

A: Moisture Sensitivity Level 2A indicates the component requires controlled storage conditions. The part can be exposed to ambient conditions (30°C / 85% RH) for a maximum of 4 weeks before soldering. Extended storage requires dry-pack conditions or desiccant storage to prevent moisture absorption that could affect soldering performance.
