Key Parameters

Substitute Part Grouping Explanation

Substitution for the 564R2DF0Q68RE is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 68 pF
• Tolerance: ±5%
• Temperature Coefficient: N2000
• Operating Temperature Range: -25°C to 105°C
• Mounting Type: Through Hole
• Package Type: Radial, Disc
• Lead Spacing: 0.252" (6.40mm)
• RoHS Compliance: ROHS3 Compliant

Allowable Variation:

• Voltage Rating: Equal to or greater than 2000V

The substitute parts identified maintain identical electrical and mechanical specifications while differing only in voltage rating (where applicable) or product status. All substitutes are manufactured by Vishay within the Cera-Mite 564R series.

Parameter Comparison

Engineering Selection Recommendations

564R2DF0Q68 (Parametric Equivalent - Recommended Primary Substitute)

This part provides direct parametric equivalence to the 564R2DF0Q68RE with identical electrical and mechanical specifications. The 564R2DF0Q68 is active in production, ensuring supply chain continuity. Both parts are ROHS3 compliant and REACH affected, maintaining regulatory alignment. This substitute is suitable for direct replacement in existing designs without circuit modification.

564R3DF0Q68 (Upgrade Alternative)

This part offers enhanced voltage rating (3000V vs. 2000V) while maintaining all other specifications. The 564R3DF0Q68 is active in production and ROHS3 compliant. The increased voltage rating provides additional design margin and may be selected where enhanced reliability or future design flexibility is required. Physical dimensions and lead spacing remain identical, enabling direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 564R3DF0Q68 be used as a direct replacement for the 564R2DF0Q68RE?

A: Yes. The 564R3DF0Q68 maintains identical capacitance, tolerance, temperature coefficient, operating temperature range, mounting type, package configuration, and lead spacing. The higher voltage rating (3000V vs. 2000V) is compatible with circuits designed for 2000V operation.

Q: What is the difference between the 564R2DF0Q68 and 564R3DF0Q68?

A: Both parts are identical except for voltage rating. The 564R2DF0Q68 is rated for 2000V, while the 564R3DF0Q68 is rated for 3000V. All other electrical and mechanical parameters are equivalent.

Q: Are all substitute parts physically compatible with the original PCB layout?

A: Yes. All substitute parts share identical physical dimensions (0.291" diameter), height (0.480" maximum), and lead spacing (0.252"). No PCB modifications are required.

Q: Do the substitute parts meet the same regulatory requirements as the original part?

A: Yes. All substitute parts are ROHS3 compliant and REACH affected, matching the regulatory status of the 564R2DF0Q68RE.

Q: Why is the 564R2DF0Q68RE listed as obsolete?

A: The 564R2DF0Q68RE is obsolete, but active equivalents (564R2DF0Q68 and 564R3DF0Q68) are available from Vishay. These active alternatives provide identical or enhanced performance for new designs and field replacements.
