Substitute Part Grouping Explanation

Substitute parts for the CDV16FF301JO3 are identified based on strict equivalence of the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 300 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage rating: 1 kV (exact match required)
• Dielectric material: Mica (exact match required)

Mechanical Compatibility Criteria:

• Mounting type: Through Hole (exact match required)
• Package case: Radial (exact match required)
• Lead spacing: within 0.002" (0.05mm) variance acceptable for PCB hole alignment

Environmental Compatibility Criteria:

• Operating temperature range: -55°C ~ 150°C (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

The substitute part CDV16FF301JO3F meets all electrical and mechanical equivalence criteria. Minor variations in lead spacing (0.232" vs. 0.234") fall within standard manufacturing tolerance for radial through-hole components and do not affect PCB compatibility.

Engineering Selection Recommendations

CDV16FF301JO3F is a direct electrical and mechanical substitute for CDV16FF301JO3.

Selection Basis:

1. Electrical Equivalence: Both parts are identical in capacitance (300 pF), tolerance (±5%), voltage rating (1 kV), and dielectric material (mica). They are functionally interchangeable in circuit applications.

2. Mechanical Compatibility: Lead spacing variance of 0.002" (0.04mm) is within standard manufacturing tolerance for radial through-hole capacitors and does not affect PCB hole alignment or mounting.

3. Environmental Performance: Both parts operate across the identical temperature range (-55°C ~ 150°C) and share MSL rating of 1 (Unlimited).

4. Compliance Advantage: CDV16FF301JO3F offers ROHS3 compliance and REACH unaffected status, compared to the main part's RoHS non-compliance and REACH affected status. This makes the substitute preferable for applications subject to environmental regulations.

5. Availability: CDV16FF301JO3F has 3,368 units in stock versus 1,048 units for the main part, providing superior supply chain reliability.

Selection Criteria Summary:

• Same manufacturer (Cornell Dubilier Electronics)
• Same series (CDV16)
• Identical electrical specifications
• Identical mechanical form factor
• Improved regulatory compliance
• Higher inventory availability

Frequently Asked Questions (FAQ)

Q: Can CDV16FF301JO3F replace CDV16FF301JO3 in existing designs?

A: Yes. CDV16FF301JO3F is electrically and mechanically equivalent. All critical parameters (capacitance, voltage, tolerance, dielectric, temperature range, mounting type, package case) are identical. The 0.002" lead spacing variance is within standard manufacturing tolerance for radial through-hole components and does not affect PCB compatibility.

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

A: The primary differences are compliance certifications and inventory levels. CDV16FF301JO3F is ROHS3 compliant and REACH unaffected, while CDV16FF301JO3 is RoHS non-compliant and REACH affected. Both are manufactured by Cornell Dubilier Electronics in the CDV16 series with identical electrical and mechanical specifications.

Q: Are there any lead spacing concerns with the 0.002" difference?

A: No. The lead spacing difference (0.234" vs. 0.232") is 0.002" (0.04mm), which falls within standard manufacturing tolerance for radial through-hole capacitors. PCB hole patterns designed for 0.234" spacing will accommodate 0.232" leads without fit issues.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements and supply chain priorities. For applications requiring RoHS3 compliance or REACH compliance, CDV16FF301JO3F is the appropriate choice. For applications without these requirements, either part is suitable. CDV16FF301JO3F offers higher inventory availability (3,368 vs. 1,048 units).

Q: Are both parts still in active production?

A: Yes. Both CDV16FF301JO3 and CDV16FF301JO3F are listed as active products from Cornell Dubilier Electronics.

Q: What are the RF performance characteristics?

A: Both parts are specified with RF, High Q, and Low Loss features, indicating suitability for radio frequency applications requiring minimal signal loss and high quality factor.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. The identical package case (radial), mounting type (through hole), and form factor (0.449" L x 0.161" W, 0.469" max height) ensure direct PCB compatibility. The minor lead spacing variance does not affect assembly or functionality.
