CDV19FF271JO3 Equivalent & Substitute Parts

Part Overview

The CDV19FF271JO3 is a 270 pF mica capacitor rated for 1 kV, manufactured by Cornell Dubilier Electronics (CDE) in the CDV19 series. This through-hole radial component is designed for general-purpose applications requiring stable capacitance and high voltage performance across extended temperature ranges (-55°C to 125°C). The part is currently active in production with 828 units in stock. Identification of equivalent substitute parts becomes necessary when the original part number is unavailable or when compliance requirements differ between procurement specifications and application needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDV19FF271JO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value (270 pF), tolerance (±5%), and voltage rating (1 kV) must be identical. The mica dielectric material is a defining characteristic of this component class and cannot be substituted with alternative dielectric types.

Mechanical Parameters: Mounting configuration (through-hole radial), lead spacing (0.343" / 8.70 mm), and physical envelope dimensions must match to ensure PCB compatibility without redesign.

Environmental Parameters: Operating temperature range (-55°C to 125°C) establishes the thermal performance envelope required for the application.

Parts meeting all these criteria are classified as direct substitutes. Variations in regulatory compliance status (RoHS, REACH) do not affect electrical or mechanical substitutability but may impact procurement eligibility based on end-use requirements.

Parameter Comparison

Engineering Selection Recommendations

CDV19FF271JO3F as Direct Substitute: The CDV19FF271JO3F is a direct electrical and mechanical equivalent to the CDV19FF271JO3. All functional parameters—capacitance, tolerance, voltage rating, dielectric material, mounting configuration, and thermal performance—are identical. Both parts are active products with adequate inventory availability.

Compliance Differentiation: The primary distinction between these parts is regulatory compliance status. The CDV19FF271JO3F carries ROHS3 compliance and REACH Unaffected status, whereas the CDV19FF271JO3 is RoHS non-compliant and REACH Affected. Selection between these parts should be based on end-use market requirements and procurement specifications. Applications subject to RoHS3 or REACH restrictions must use CDV19FF271JO3F. Applications without such restrictions may use either part based on availability and cost considerations.

Interchangeability: From an engineering standpoint, these parts are fully interchangeable in circuit design and PCB layout. No design modifications are required when substituting between CDV19FF271JO3 and CDV19FF271JO3F.

Frequently Asked Questions (FAQ)

Q: Can CDV19FF271JO3F replace CDV19FF271JO3 in my design?

A: Yes. The CDV19FF271JO3F is electrically and mechanically identical to the CDV19FF271JO3. All electrical parameters (270 pF, ±5%, 1 kV), physical dimensions, lead spacing, and thermal characteristics are equivalent. No circuit or PCB modifications are required.

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

A: The parts are functionally identical. The difference lies in regulatory compliance: CDV19FF271JO3F is ROHS3 compliant and REACH Unaffected, while CDV19FF271JO3 is RoHS non-compliant and REACH Affected. The "F" suffix in CDV19FF271JO3F indicates the compliant variant.

Q: Will these parts fit the same PCB footprint?

A: Yes. Both parts have identical lead spacing (0.343" / 8.70 mm), physical dimensions (0.642" L × 0.189" W), and radial package configuration. They occupy the same PCB footprint without modification.

Q: Are there any temperature or voltage derating considerations between these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 125°C) and share the same 1 kV voltage rating. Performance characteristics are equivalent across all operating conditions.

Q: Which part should I specify for new designs?

A: For new designs subject to RoHS3 or REACH compliance requirements, specify CDV19FF271JO3F. For applications without such restrictions, either part is acceptable based on availability and procurement policy.

Q: Are both parts currently available?

A: Yes. CDV19FF271JO3 has 828 units in stock, and CDV19FF271JO3F has 811 units in stock. Both are active products.
