Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 564RY5FRE302EC151K is determined by the following critical parameters:

• Capacitance Value: Must be 150 pF
• Voltage Rating: Must be 3000V (3kV) or higher
• Mounting Type: Must be Through Hole
• Package Type: Must be Radial, Disc
• Lead Style: Must be Straight
• RoHS Compliance: Must maintain ROHS3 Compliant status

The identified substitute part 564RC0GAA302EP151J meets all these criteria. While the temperature coefficient differs (C0G/NP0 versus Y5F) and tolerance is tighter (±5% versus ±10%), these represent improvements in performance characteristics rather than incompatibilities. The substitute maintains identical capacitance, voltage rating, mounting configuration, and environmental compliance.

Parameter Comparison

Engineering Selection Recommendations

The 564RC0GAA302EP151J is the qualified substitute for the obsolete 564RY5FRE302EC151K. Selection of this substitute is supported by:

• Product Status: The substitute is active, ensuring long-term availability and supply chain continuity, whereas the main part is obsolete.
• Regulatory Compliance: Both parts maintain ROHS3 Compliant status, satisfying environmental and regulatory requirements.
• Electrical Equivalence: Identical capacitance (150 pF) and voltage rating (3000V) ensure functional compatibility in circuit applications.
• Physical Compatibility: Matching through-hole mounting, radial disc package, and straight lead configuration enable direct board-level substitution without layout modifications.
• Performance Enhancement: The substitute offers tighter tolerance (±5% versus ±10%) and superior temperature stability (C0G/NP0 coefficient), representing performance improvements for applications requiring enhanced precision.

Frequently Asked Questions (FAQ)

Q: Can the 564RC0GAA302EP151J be used as a direct replacement for the 564RY5FRE302EC151K?

A: Yes. Both parts share identical capacitance (150 pF), voltage rating (3000V), mounting type (through hole), and package configuration (radial disc). The physical footprint and electrical performance are compatible for direct substitution.

Q: What is the difference between Y5F and C0G/NP0 temperature coefficients?

A: Y5F and C0G/NP0 are different temperature coefficient classifications. C0G/NP0 provides superior temperature stability with minimal capacitance variation across the operating range, whereas Y5F exhibits greater capacitance variation with temperature. The substitute's C0G/NP0 coefficient represents improved performance for temperature-sensitive applications.

Q: Does the tighter tolerance of the substitute part affect compatibility?

A: No. The substitute's ±5% tolerance is tighter than the main part's ±10% tolerance, meaning it provides better capacitance accuracy. This represents an improvement and does not create compatibility issues.

Q: Are both parts RoHS compliant?

A: Yes. Both the 564RY5FRE302EC151K and 564RC0GAA302EP151J are ROHS3 Compliant, meeting environmental and regulatory standards.

Q: Why is the main part listed as obsolete?

A: The 564RY5FRE302EC151K is classified as obsolete, indicating it is no longer in active production. The substitute 564RC0GAA302EP151J is active and available, providing continued access to equivalent functionality.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The identical electrical specifications (150 pF, 3000V), matching physical package (radial disc, through hole), and compatible lead configuration enable interchangeable use without design modifications.
