CD19FD122GO3 Equivalent & Substitute Parts

Part Overview

The Cornell Dubilier Electronics CD19FD122GO3 is a 1200 pF mica capacitor rated for 500 V operation with ±2% tolerance. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. Finding equivalent or substitute parts is necessary when managing inventory, addressing component obsolescence, or selecting variants that meet updated compliance requirements such as RoHS3 compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD19FD122GO3 are determined by equivalence across electrical and mechanical parameters. The primary substitution criterion is maintenance of the complete electrical specification: 1200 pF capacitance at ±2% tolerance, 500 V rated voltage, and mica dielectric composition. Secondary criteria include identical mounting type (through hole), package configuration (radial), and physical dimensions to ensure direct drop-in compatibility in PCB layouts. All substitute parts must operate within the same temperature range (-55°C to 125°C) and maintain the same lead spacing (0.343") for footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both CD19FD122GO3 and CD19FD122GO3F are electrically and mechanically equivalent components from the same manufacturer and series. Selection between these parts depends on regulatory and compliance requirements. The CD19FD122GO3F is ROHS3 compliant and REACH unaffected, making it the appropriate choice for applications subject to RoHS3 regulatory requirements or supply chains requiring REACH compliance status. The original CD19FD122GO3 is RoHS non-compliant and REACH affected, and remains suitable only for applications with no compliance constraints or legacy systems where such constraints do not apply. Both parts share identical electrical performance and physical packaging, ensuring direct interchangeability from a functional and PCB layout perspective.

Frequently Asked Questions (FAQ)

Q: Are the CD19FD122GO3 and CD19FD122GO3F electrically identical? A: Yes. Both parts have identical capacitance (1200 pF), tolerance (±2%), rated voltage (500 V), dielectric material (mica), and operating temperature range (-55°C to 125°C).

Q: Can CD19FD122GO3F replace CD19FD122GO3 on a PCB? A: Yes. The parts are mechanically identical with the same lead spacing (0.343"), dimensions (0.661" L x 0.220" W), and radial through-hole package configuration, enabling direct PCB substitution.

Q: What is the key difference between these two parts? A: The CD19FD122GO3F is ROHS3 compliant and REACH unaffected, while the CD19FD122GO3 is RoHS non-compliant and REACH affected. Select the compliant variant (CD19FD122GO3F) for applications requiring regulatory adherence.

Q: Are there inventory or availability differences between these parts? A: Inventory levels are provided separately and should be verified with the supplier. The CD19FD122GO3 shows 775 pieces in stock, while the CD19FD122GO3F shows 1021 pieces.

Q: Does the RoHS status affect electrical performance? A: No. RoHS compliance status reflects manufacturing process and material composition changes but does not affect the electrical specifications or performance of the capacitor.
