Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDV16FF751JO3 are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

Electrical Parameters (Non-negotiable):

• Capacitance value: 750 pF (exact match required)
• Tolerance: ±5% (minimum acceptable)
• Voltage rating: 1 kV (minimum acceptable)
• Dielectric material: Mica (required for RF performance and temperature stability)

Mechanical Parameters (Non-negotiable):

• Mounting type: Through Hole Radial (PCB compatibility)
• Lead spacing: 0.234" (5.94mm) (footprint compatibility)
• Package case: Radial (form factor requirement)

Performance Characteristics (Required):

• RF-grade performance with High Q and Low Loss properties
• Operating temperature range: -55°C to 150°C (minimum acceptable)

Compliance and Availability:

• Product status: Active (current production)
• Series: CDV16 (Cornell Dubilier Electronics CDV series)

Parts meeting all these criteria are classified as direct substitutes and can be used interchangeably in circuit applications without design modification.

Parameter Comparison

Engineering Selection Recommendations

CDV16FF751JO3F as Direct Substitute:

The CDV16FF751JO3F is a direct electrical and mechanical substitute for the CDV16FF751JO3. All critical parameters including capacitance, tolerance, voltage rating, dielectric material, mounting configuration, and lead spacing are identical. Both components are Active product status from the same manufacturer and series.

Compliance Differentiation:

The primary distinction between these parts is regulatory compliance status:

• CDV16FF751JO3: RoHS non-compliant; REACH Affected
• CDV16FF751JO3F: ROHS3 Compliant; REACH Unaffected

Selection between these parts should be based on application requirements and regulatory obligations. Applications subject to RoHS3 directives or REACH restrictions require the CDV16FF751JO3F variant. Applications without such compliance requirements may use either part. Both components maintain identical electrical performance and physical characteristics.

Inventory Availability:

Both parts are available in production quantities. The CDV16FF751JO3F maintains slightly higher inventory (830 pcs vs. 793 pcs), which may influence supply chain planning decisions.

Frequently Asked Questions (FAQ)

Q: Can CDV16FF751JO3F replace CDV16FF751JO3 in existing designs without PCB modification?

A: Yes. The CDV16FF751JO3F is a direct substitute with identical electrical specifications, capacitance value (750 pF), tolerance (±5%), voltage rating (1 kV), and physical dimensions including lead spacing (0.234" / 5.94mm). No PCB layout changes are required for direct replacement.

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

A: The electrical and mechanical specifications are identical. The difference is in regulatory compliance: CDV16FF751JO3F is ROHS3 Compliant and REACH Unaffected, while CDV16FF751JO3 is RoHS non-compliant and REACH Affected. Select based on your application's compliance requirements.

Q: Are both parts suitable for RF applications?

A: Yes. Both CDV16FF751JO3 and CDV16FF751JO3F are RF-grade mica capacitors with High Q and Low Loss characteristics. They are functionally equivalent for RF circuit applications.

Q: What is the operating temperature range for these capacitors?

A: Both parts operate across -55°C to 150°C. This wide temperature range makes them suitable for industrial and military applications requiring stable capacitance performance across extreme environmental conditions.

Q: Can these parts be used in applications requiring RoHS compliance?

A: Only the CDV16FF751JO3F meets RoHS3 compliance requirements. If your application or end-market requires RoHS certification, use the CDV16FF751JO3F variant exclusively.

Q: What is the moisture sensitivity level (MSL) for these capacitors?

A: Both parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity concerns. These components can be stored and handled without special moisture control measures.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts have identical dimensions: 0.461" L x 0.173" W (11.70mm x 4.40mm) with maximum seated height of 0.500" (12.70mm). Lead spacing is 0.234" (5.94mm) for both variants.

Q: Which part should I select for new designs?

A: For new designs, CDV16FF751JO3F is recommended due to ROHS3 compliance and REACH Unaffected status, ensuring compatibility with current and future regulatory requirements. Both parts are electrically and mechanically identical, so the compliance advantage of the F variant makes it the preferred choice for forward compatibility.
