GP322 Equivalent & Substitute Parts

Part Overview

The Cornell Dubilier Electronics GP322 is a 220 pF ceramic capacitor rated for 1000V (1kV) with Y5P temperature coefficient, designed for general-purpose applications in through-hole radial disc configurations. The GP322 is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility. Substitute parts must match the core electrical specifications: 220 pF capacitance, ±10% tolerance, 1000V rated voltage, radial through-hole mounting, and compatible physical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Mandatory Matching Parameters:

• Capacitance: 220 pF
• Tolerance: ±10%
• Voltage - Rated: 1000V (1kV)
• Mounting Type: Through Hole
• Package / Case: Radial, Disc
• Lead Spacing: 0.252" (6.40mm)
• Lead Style: Straight

Variable Parameters (Non-Restrictive):

• Temperature Coefficient: Y5P (main part) vs. N2500 or X5F (substitutes) — different temperature stability characteristics but functionally compatible for general-purpose applications
• Operating Temperature Range: Extended range in substitutes (-55°C ~ 105°C) provides broader operational envelope than main part (-30°C ~ 85°C)
• Product Status: Active substitutes replace obsolete main part

All identified substitute parts meet the mandatory electrical and mechanical parameters, enabling direct functional replacement in through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (N2500 Temperature Coefficient): 561R1DF0T22 and 561R1DF0T22JK are Vishay Cera-Mite active alternatives with N2500 temperature coefficient. Both parts maintain identical electrical specifications to the GP322 and are ROHS3 compliant. The N2500 coefficient provides tighter temperature stability compared to the Y5P specification of the main part. These substitutes are suitable for applications requiring extended operating temperature range (-55°C ~ 105°C) and are available in high inventory quantities.

Secondary Substitutes (X5F Temperature Coefficient): 562R10TST22, 562R10TST22UB, and 562R5GAT22 are Vishay Cera-Mite active alternatives with X5F temperature coefficient. These parts meet all mandatory electrical and mechanical parameters. The X5F coefficient offers different temperature stability characteristics than both Y5P and N2500. All three X5F variants are ROHS3 compliant and available in substantial inventory. The 562R5GAT22 variant has the highest inventory availability (9200 pcs).

Compliance Considerations: All substitute parts are ROHS3 compliant, matching the regulatory status of the obsolete GP322. The Vishay substitutes provide active product status, ensuring long-term availability and supply chain continuity compared to the obsolete Cornell Dubilier part.

Frequently Asked Questions (FAQ)

Q: Can the Vishay Cera-Mite substitutes be used as direct replacements for the GP322 in existing designs?

A: Yes. All identified Vishay substitutes match the mandatory electrical parameters (220 pF, ±10%, 1000V) and mechanical specifications (through-hole radial disc, 0.252" lead spacing, straight leads). Physical board layout compatibility is maintained. Temperature coefficient differences (Y5P vs. N2500 vs. X5F) do not prevent functional substitution in general-purpose applications.

Q: What is the difference between the N2500 and X5F temperature coefficient substitutes?

A: Temperature coefficient designations indicate different temperature stability characteristics. N2500 and X5F are distinct classifications with different capacitance variation curves across the operating temperature range. Both are compatible with the GP322 application requirements. Selection between these variants depends on specific circuit temperature stability requirements.

Q: Are there physical dimension differences between the GP322 and substitute parts?

A: The GP322 has a 0.236" diameter (6.00mm), while all Vishay substitutes have a 0.252" diameter (6.40mm). Lead spacing remains identical at 0.252" (6.40mm). The slightly larger body diameter of substitutes requires verification of available PCB board space, though radial disc geometry remains unchanged.

Q: Do all substitute parts have the same RoHS compliance status?

A: Yes. The GP322 and all five Vishay substitute parts are ROHS3 compliant, ensuring regulatory compatibility for applications requiring RoHS certification.

Q: Which substitute part should be selected for new designs?

A: Selection is based on temperature coefficient requirements and inventory availability. For applications within the GP322 operating range (-30°C ~ 85°C), any substitute is functionally equivalent. The 562R5GAT22 (X5F, 9200 pcs available) offers maximum inventory availability. The 561R1DF0T22 and 561R1DF0T22JK (N2500) provide alternative temperature stability characteristics with active product status.

Q: Are the substitute parts available in the same packaging as the GP322?

A: All substitute parts are supplied in bulk packaging, consistent with the GP322 packaging specification. Lead style (straight) and mounting type (through-hole) are identical across all parts.
