CD19FD271JO3 Equivalent & Substitute Parts

Part Overview

The CD19FD271JO3 is a 270 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE) in the CD19 series. This through-hole radial component operates at 500 V rated voltage with ±5% tolerance and is designed for general-purpose applications across an operating temperature range of -55°C to 125°C. The part is currently active in production with 1099 units in stock. Identifying equivalent substitute parts is necessary when the primary part becomes unavailable, when compliance requirements change, or when alternative sourcing is required for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD19FD271JO3 are determined by strict equivalence across the following critical parameters:

• Capacitance Value: 270 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Material: Mica (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: Radial (exact match required)
• Lead Spacing: 0.343" (8.70mm) (exact match required)
• Physical Dimensions: 0.642" L x 0.189" W, Height 0.500" max (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

The CD19FD271JO3F qualifies as a parametric equivalent because it maintains identical electrical and mechanical specifications across all these parameters. Differences in RoHS compliance status and REACH classification do not affect functional substitutability but are relevant for regulatory and procurement contexts.

Parameter Comparison

Engineering Selection Recommendations

The CD19FD271JO3F serves as a direct parametric equivalent to the CD19FD271JO3 for applications requiring identical electrical and mechanical performance. Selection between these parts should be based on regulatory and compliance requirements:

CD19FD271JO3: Select this part for applications where RoHS non-compliance is acceptable and REACH-affected status does not present procurement constraints. Current inventory of 1099 units supports immediate availability.

CD19FD271JO3F: Select this part for applications subject to RoHS3 compliance mandates or where REACH-unaffected status is a procurement requirement. This variant maintains full electrical and mechanical equivalence while addressing enhanced regulatory compliance. Current inventory of 964 units is available.

Both parts are active products from Cornell Dubilier Electronics and are suitable for direct substitution in circuit designs without modification to PCB layouts, schematic connections, or electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can CD19FD271JO3F be used as a direct replacement for CD19FD271JO3 in existing designs?

A: Yes. The CD19FD271JO3F is electrically and mechanically identical to the CD19FD271JO3. Both parts have the same capacitance (270 pF), tolerance (±5%), voltage rating (500 V), dielectric material (mica), mounting type (through hole), package configuration (radial), lead spacing (0.343"), physical dimensions, and operating temperature range (-55°C to 125°C). No circuit modifications or PCB layout changes are required.

Q: What is the difference between CD19FD271JO3 and CD19FD271JO3F?

A: The primary differences are regulatory compliance classifications. The CD19FD271JO3F is ROHS3 compliant and REACH unaffected, while the CD19FD271JO3 is RoHS non-compliant and REACH affected. All electrical and mechanical parameters are identical.

Q: Which part should I select for a new design?

A: Selection depends on your application's regulatory requirements. If RoHS3 compliance is required, use CD19FD271JO3F. If RoHS compliance is not a constraint, either part is suitable. Consult your procurement and compliance departments for specific requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical dimensions: 0.642" length x 0.189" width (16.30mm x 4.80mm), with a maximum seated height of 0.500" (12.70mm). Lead spacing is 0.343" (8.70mm) for both parts. They are mechanically interchangeable on PCBs designed for either variant.

Q: What is the lead spacing for these radial capacitors?

A: The lead spacing is 0.343 inches, equivalent to 8.70 millimeters. This dimension is critical for PCB footprint design and must match the hole spacing on the circuit board.

Q: Are both parts currently in stock?

A: Yes. CD19FD271JO3 has 1099 units in stock, and CD19FD271JO3F has 964 units in stock. Both are available as new original components.
