CDV19CF050DO3 Equivalent & Substitute Parts

Part Overview

The CDV19CF050DO3 is a 5 pF mica capacitor rated for 1 kV with ±0.5% tolerance, manufactured by Cornell Dubilier Electronics (CDE). This radial through-hole component is designed for general-purpose applications requiring high precision and stable performance across the operating temperature range of -55°C to 125°C. The part is currently active in production. Identifying equivalent substitute parts is necessary to ensure supply chain continuity, optimize inventory management, and accommodate specific compliance or packaging requirements in electronic assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDV19CF050DO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value (5 pF), tolerance specification (±0.5%), and voltage rating (1 kV) must be identical. The dielectric material (mica) is fixed for this application category.

Mechanical Parameters: Mounting type (through hole), package configuration (radial), and lead spacing (0.343" / 8.70 mm) must match to ensure direct board-level compatibility without layout modifications.

Environmental Parameters: Operating temperature range (-55°C to 125°C) must be maintained.

Series Designation: Parts must belong to the CDV19 series from Cornell Dubilier Electronics.

The substitute part CDV19CF050DO3F meets all these criteria and is therefore classified as a direct equivalent within the same manufacturer series.

Parameter Comparison

Engineering Selection Recommendations

CDV19CF050DO3F as Primary Substitute:

The CDV19CF050DO3F is a direct functional equivalent to the CDV19CF050DO3 across all electrical, mechanical, and environmental parameters. Both parts are active products from the same manufacturer series.

Compliance Considerations:

The CDV19CF050DO3F offers improved regulatory compliance status. It is ROHS3 compliant and REACH unaffected, whereas the original CDV19CF050DO3 is RoHS non-compliant and REACH affected. Selection of CDV19CF050DO3F is appropriate for applications subject to RoHS3 or REACH regulatory requirements.

Inventory and Availability:

CDV19CF050DO3F has higher current inventory availability (1281 pcs) compared to CDV19CF050DO3 (722 pcs), supporting supply chain continuity.

Application Compatibility:

Both parts are suitable for identical circuit applications. No circuit redesign or board layout modification is required when substituting between these parts. The radial through-hole configuration, lead spacing, and physical dimensions are identical.

Frequently Asked Questions (FAQ)

Q: Can CDV19CF050DO3F be used as a direct replacement for CDV19CF050DO3 on existing PCBs?

A: Yes. The CDV19CF050DO3F is mechanically and electrically identical to CDV19CF050DO3. Lead spacing (0.343" / 8.70 mm), package type (radial), and physical dimensions are identical. No PCB modifications are required.

Q: What is the difference between the tolerance specifications ±0.5% and ±0.5 pF for a 5 pF capacitor?

A: For a 5 pF capacitor, ±0.5% tolerance equals ±0.025 pF, which is tighter than ±0.5 pF. The CDV19CF050DO3F tolerance specification (±0.5 pF) is less stringent but remains compatible with applications designed for the original part.

Q: Are there compliance differences between these two parts?

A: Yes. CDV19CF050DO3F is ROHS3 compliant and REACH unaffected, while CDV19CF050DO3 is RoHS non-compliant and REACH affected. Applications subject to RoHS3 or REACH regulations should use CDV19CF050DO3F.

Q: Do both parts have the same voltage rating and operating temperature range?

A: Yes. Both CDV19CF050DO3 and CDV19CF050DO3F are rated for 1 kV and operate across -55°C to 125°C.

Q: Is the radial through-hole package identical for both parts?

A: Yes. Both parts use identical radial through-hole packaging with 0.343" (8.70 mm) lead spacing, 0.642" L x 0.189" W (16.30 mm x 4.80 mm) dimensions, and 0.500" (12.70 mm) maximum seated height.
