Key Parameters

Substitute Part Grouping Explanation

Substitution for the 564R2DF0Q68KA 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 / Case: Radial, Disc
• Lead Spacing: 0.252" (6.40mm)
• RoHS Status: ROHS3 Compliant

Voltage Rating Consideration: The voltage rating may be equal to or greater than the original specification. A higher voltage rating maintains electrical safety margins and circuit reliability.

Two substitute parts meet these criteria:

1. 564R3DF0Q68 — Upgrade substitute with 3000V (3kV) rating
2. 564R2DF0Q68 — Parametric equivalent with identical 2000V (2kV) rating

Parameter Comparison

Engineering Selection Recommendations

564R2DF0Q68 (Parametric Equivalent)

This part is the direct parametric equivalent to the 564R2DF0Q68KA. It maintains identical electrical specifications and physical dimensions while offering active product status. This part is suitable for direct replacement in applications where the original 2000V rating is specified and required.

564R3DF0Q68 (Upgrade Substitute)

This part provides an upgraded voltage rating of 3000V (3kV) while maintaining all other electrical and mechanical parameters. The higher voltage rating provides additional safety margin in high-voltage applications. This part is suitable for replacement when circuit design permits operation at the higher voltage specification.

Both substitute parts are ROHS3 compliant and REACH affected, matching the regulatory status of the original component.

Frequently Asked Questions (FAQ)

Q: Can 564R2DF0Q68 be used as a direct replacement for 564R2DF0Q68KA?

A: Yes. The 564R2DF0Q68 is a parametric equivalent with identical capacitance, tolerance, voltage rating, temperature coefficient, and physical dimensions. The primary difference is product status: the original is obsolete while the equivalent is active.

Q: What is the difference between 564R3DF0Q68 and 564R2DF0Q68KA?

A: The 564R3DF0Q68 has a higher voltage rating of 3000V compared to the 2000V rating of the original. All other parameters—capacitance, tolerance, temperature coefficient, operating temperature range, and physical dimensions—are identical.

Q: Can I use 564R3DF0Q68 in place of 564R2DF0Q68KA?

A: Yes, provided the circuit design permits operation at the higher 3000V voltage rating. The upgrade substitute maintains all other electrical and mechanical compatibility.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share the same radial disc package with 0.291" diameter (7.40mm), 0.480" maximum seated height (12.20mm), and 0.252" lead spacing (6.40mm).

Q: Do all substitute parts meet the same compliance standards?

A: Yes. Both substitute parts are ROHS3 compliant and REACH affected, matching the regulatory status of the original 564R2DF0Q68KA.
