Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDV16FF501JO3 is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Capacitance value: 500 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage rating: 1 kV (minimum; higher ratings acceptable)
• Dielectric type: Mica (exact match required)
• Mounting configuration: Through Hole Radial (exact match required)
• Operating temperature range: -55°C to 150°C (minimum coverage required)

Compatible Variation Parameters:

• Lead spacing: 0.232" to 0.234" (5.90mm to 5.94mm) - minor mechanical tolerance acceptable within standard PCB hole spacing
• Physical dimensions: Variations within 0.002" acceptable for length and width without affecting mounting integrity
• RoHS and REACH compliance status: May differ based on application requirements

The CDV16FF501JO3F qualifies as a direct substitute based on matching all critical parameters while maintaining mechanical compatibility within standard manufacturing tolerances.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The CDV16FF501JO3F serves as a direct electrical and mechanical equivalent to the CDV16FF501JO3. Both components share identical electrical specifications across capacitance, tolerance, voltage rating, temperature range, and dielectric material. The 0.002" (0.04mm) difference in lead spacing (5.90mm versus 5.94mm) falls within standard PCB manufacturing tolerances and does not affect footprint compatibility.

Compliance Considerations:

The CDV16FF501JO3F provides enhanced regulatory compliance status. It is ROHS3 compliant, whereas the original part is RoHS non-compliant. Additionally, the substitute is REACH Unaffected, compared to the original part's REACH Affected status. These compliance differences may be significant for applications subject to European Union regulations or customer-specific compliance requirements.

Inventory and Availability:

The CDV16FF501JO3F maintains higher inventory levels (1384 units) compared to the CDV16FF501JO3 (946 units), providing improved supply chain reliability for production planning.

Application Compatibility:

Both parts are suitable for RF applications requiring high Q and low loss characteristics. The identical operating temperature range (-55°C to 150°C) and moisture sensitivity level (MSL 1 - Unlimited) ensure equivalent performance in demanding environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can CDV16FF501JO3F be used as a direct replacement for CDV16FF501JO3 in existing designs?

A: Yes. The CDV16FF501JO3F is electrically and mechanically equivalent. All critical parameters including capacitance (500 pF), tolerance (±5%), voltage rating (1 kV), dielectric material (Mica), and mounting configuration (Through Hole Radial) are identical. The lead spacing difference of 0.002" (0.04mm) is within standard PCB manufacturing tolerances.

Q: What is the significance of the RoHS compliance difference?

A: The CDV16FF501JO3F is ROHS3 compliant, while the CDV16FF501JO3 is RoHS non-compliant. This distinction is relevant for applications subject to European Union Restriction of Hazardous Substances regulations or customer specifications requiring RoHS compliance. For applications without such requirements, both parts are functionally equivalent.

Q: Does the REACH status difference affect component performance?

A: No. REACH status relates to regulatory compliance and substance registration requirements, not electrical or mechanical performance. The CDV16FF501JO3F's REACH Unaffected status simplifies compliance documentation for certain applications, but both parts deliver identical electrical characteristics.

Q: Are the physical dimensions compatible with the same PCB footprint?

A: Yes. Both parts share identical body dimensions (0.449" L x 0.161" W) and maximum seated height (0.469"). The lead spacing variation (0.234" versus 0.232") is within standard PCB hole tolerance specifications and does not require footprint redesign.

Q: Which part should be selected for new designs?

A: The CDV16FF501JO3F is recommended for new designs due to superior compliance status (ROHS3 compliant, REACH Unaffected) and higher inventory availability. Both parts are electrically identical, making the substitute the preferred choice for forward compatibility and supply chain stability.

Q: Is there any performance difference in RF applications?

A: No. Both parts are specified with identical RF, High Q, and Low Loss features. Operating temperature range (-55°C to 150°C) and moisture sensitivity level (MSL 1) are identical, ensuring equivalent performance in RF circuits and high-frequency applications.

Q: Can these parts be intermixed in production?

A: Yes, provided the application does not have specific compliance requirements that exclude the non-compliant variant. For applications requiring RoHS or REACH compliance, only the CDV16FF501JO3F should be used. For applications without such constraints, both parts are interchangeable.
