CD19FD621JO3 Equivalent & Substitute Parts

Part Overview

The CD19FD621JO3 is a 620 pF mica capacitor rated for 500 V operation in a radial through-hole package, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as active and suitable for general-purpose applications requiring stable capacitance and high voltage performance across extended temperature ranges (-55°C to 125°C).

Identification of substitute parts becomes necessary when the primary part number experiences supply constraints, inventory limitations, or when design requirements mandate compliance with specific regulatory standards such as RoHS or REACH certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD19FD621JO3 are identified based on strict parametric equivalence. The substitution logic is based exclusively on the following criteria:

Electrical Parameters (Non-negotiable):

• Capacitance value: 620 pF (exact match required)
• Tolerance: ±5% (minimum acceptable)
• Voltage rating: 500 V (minimum acceptable)
• Dielectric material: Mica (exact match required)

Mechanical Parameters (Non-negotiable):

• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.343" / 8.70mm (exact match required)

Environmental Parameters (Non-negotiable):

• Operating temperature range: -55°C to 125°C (minimum acceptable)

Regulatory & Compliance Parameters (Application-dependent):

• RoHS compliance status
• REACH compliance status
• Product status (Active)

Parts meeting all electrical, mechanical, and environmental parameters are classified as parametric equivalents and direct substitutes. Regulatory compliance differences do not disqualify substitution but must be evaluated against application requirements.

Engineering Selection Recommendations

CD19FD621JO3F as Direct Substitute:

The CD19FD621JO3F is a parametric equivalent to the CD19FD621JO3. Both parts are manufactured by Cornell Dubilier Electronics within the CD19 series and share identical electrical, mechanical, and environmental specifications.

Regulatory Compliance Considerations:

The primary distinction between these parts is regulatory compliance status:

• CD19FD621JO3: RoHS non-compliant; REACH Affected
• CD19FD621JO3F: RoHS3 Compliant; REACH Unaffected

Selection between these parts depends on application requirements:

1. Applications requiring RoHS3 compliance: Use CD19FD621JO3F
2. Applications with no RoHS compliance requirement: Either part is acceptable based on availability and supply chain considerations
3. Applications subject to REACH regulations: CD19FD621JO3F is preferred due to REACH Unaffected status

Inventory Availability:

• CD19FD621JO3: 1096 pcs in stock
• CD19FD621JO3F: 1580 pcs in stock

Both parts maintain active product status and are available for immediate procurement.

Frequently Asked Questions (FAQ)

Q: Can CD19FD621JO3F replace CD19FD621JO3 in all applications?

A: CD19FD621JO3F is a parametric equivalent with identical electrical, mechanical, and environmental specifications. Substitution is valid for all applications where the original part was specified, provided regulatory compliance requirements do not mandate the non-compliant variant.

Q: What is the difference between these two part numbers?

A: The parts are electrically and mechanically identical. The suffix "F" in CD19FD621JO3F indicates RoHS3 compliance and REACH Unaffected status, whereas the CD19FD621JO3 is RoHS non-compliant and REACH Affected.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical dimensions: 0.650" L x 0.201" W (16.50mm x 5.10mm), height of 0.512" (13.00mm), and lead spacing of 0.343" (8.70mm). PCB footprints are interchangeable.

Q: Which part should I select for new designs?

A: For new designs, CD19FD621JO3F is recommended due to RoHS3 compliance and REACH Unaffected status, ensuring compatibility with current regulatory requirements and future supply chain standards.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Both parts are through-hole radial components with identical lead spacing and physical dimensions. They are mechanically and electrically interchangeable without PCB redesign.

Q: What is the operating temperature range for both parts?

A: Both CD19FD621JO3 and CD19FD621JO3F operate across -55°C to 125°C, providing stable performance across extended environmental conditions.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical electrical performance: 620 pF capacitance at ±5% tolerance, 500 V voltage rating, and mica dielectric material. Performance differences are limited to regulatory compliance status.
