Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS12-F2GA472MYGS is determined by the following critical parameters:

• Capacitance Value: Must be 4700 pF
• Tolerance: Must be ±20%
• Voltage Rating: Must meet or exceed 250VAC
• Safety Ratings: Must maintain X1, Y2 classification
• Mounting Configuration: Must be Through Hole with Radial, Disc package
• Lead Spacing: Must be 0.295" (7.50mm) for PCB compatibility

The VY2472M49Y5US63V7 meets all substitution criteria with a higher voltage rating (440VAC) and extended operating temperature range, providing enhanced performance margins while maintaining identical capacitance, tolerance, safety ratings, and lead spacing.

Engineering Selection Recommendations

The VY2472M49Y5US63V7 is the qualified substitute for the obsolete CS12-F2GA472MYGS. Selection is based on the following factors:

• Functional Equivalence: Identical capacitance value (4700 pF) and tolerance (±20%) ensure electrical performance parity in the circuit.
• Safety Compliance: Both components maintain X1, Y2 safety ratings, confirming suitability for safety-critical applications.
• Voltage Margin: The substitute's 440VAC rating exceeds the original 250VAC requirement, providing additional operational margin.
• Product Availability: The substitute is in active production status with substantial inventory (95,075 pcs), ensuring long-term procurement reliability.
• Regulatory Compliance: The substitute is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
• Physical Compatibility: Identical lead spacing (0.295" / 7.50mm) and through-hole radial disc package ensure direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the VY2472M49Y5US63V7 be used as a direct replacement for the CS12-F2GA472MYGS?

A: Yes. Both components have identical capacitance (4700 pF), tolerance (±20%), safety ratings (X1, Y2), lead spacing (0.295" / 7.50mm), and through-hole radial disc package configuration. The substitute's higher voltage rating (440VAC vs. 250VAC) and extended temperature range provide enhanced performance margins.

Q: What are the key differences between these two capacitors?

A: The primary differences are: voltage rating (250VAC vs. 440VAC), temperature coefficient (F vs. Y5U), operating temperature range (-25°C ~ 105°C vs. -40°C ~ 125°C), physical dimensions (12.00mm vs. 12.50mm diameter), and product status (obsolete vs. active). The substitute offers higher voltage capability and broader temperature operation.

Q: Will the substitute fit the same PCB footprint?

A: Yes. Both components have identical lead spacing of 0.295" (7.50mm) and use through-hole radial disc packages, ensuring PCB footprint compatibility. The substitute has a slightly larger diameter (12.50mm vs. 12.00mm) and greater height (16.50mm vs. 9.00mm), which must be verified for clearance in the physical layout.

Q: Are there any compliance or regulatory concerns with substitution?

A: No. Both components are REACH unaffected. The substitute is ROHS3 compliant, meeting current environmental standards. Both maintain X1, Y2 safety ratings for use in safety-critical applications.

Q: What is the impact of the different temperature coefficients?

A: The original uses temperature coefficient F, while the substitute uses Y5U (E). Both are suitable for the specified operating temperature ranges. The Y5U coefficient indicates capacitance variation over temperature; circuit design should account for this if temperature-dependent performance is critical.
