Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the CM06FD681GO3 is based on the following critical parameters that must remain constant:

• Capacitance Value: 680 pF (no tolerance variation permitted)
• Voltage Rating: 500 V minimum (higher ratings acceptable)
• Tolerance: ±2% (ensures circuit performance specifications)
• Dielectric Material: Mica (required for performance and reliability)
• Operating Temperature: -55°C to 125°C (minimum range required)
• Mounting Configuration: Through-hole radial package
• Lead Spacing: 0.343" (8.70 mm) (PCB layout compatibility)
• Physical Envelope: 0.650" L × 0.209" W maximum (board space constraints)

The CD19FD681GO3F qualifies as a parametric equivalent based on matching all critical electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The CD19FD681GO3F is a qualified parametric equivalent to the CM06FD681GO3. Both components share identical electrical specifications, physical dimensions, and mechanical compatibility for board-level installation.

Key regulatory difference: The CD19FD681GO3F carries RoHS3 compliance certification, whereas the CM06FD681GO3 is RoHS non-compliant. Selection between these parts depends on regulatory requirements of the end application. The CM06FD681GO3 remains suitable for applications not subject to RoHS requirements. The CD19FD681GO3F is required for RoHS-mandated applications.

Both components are in active production with established inventory levels (777 units and 750 units respectively), ensuring sustained availability for procurement.

Frequently Asked Questions (FAQ)

Q: Can the CD19FD681GO3F be directly substituted for the CM06FD681GO3?

A: Yes. Both components are electrically and mechanically interchangeable. All critical parameters including capacitance, voltage rating, tolerance, dielectric material, operating temperature range, mounting type, and physical envelope are identical. Board-level replacement requires no design modifications.

Q: What is the difference between the CM06 and CD19 series?

A: The CM06 and CD19 are separate product series from Cornell Dubilier Electronics with different manufacturing processes and regulatory compliance certifications. The CM06FD681GO3 is RoHS non-compliant, while the CD19FD681GO3F is RoHS3 compliant. Electrical and mechanical specifications are equivalent.

Q: Are there any MSL or moisture sensitivity considerations?

A: The CM06FD681GO3 carries an MSL rating of 1 (Unlimited), indicating unrestricted moisture sensitivity handling. The CD19FD681GO3F is rated as Not Applicable for MSL. Both configurations are suitable for standard storage and handling conditions without moisture-controlled environmental requirements.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory compliance requirements. For RoHS-mandated applications, select the CD19FD681GO3F. For applications without RoHS requirements, either part is acceptable based on availability and supply chain preference.

Q: How do lead spacing and physical dimensions affect substitution?

A: Lead spacing of 0.343" (8.70 mm) and physical envelope dimensions of 0.650" L × 0.209" W are identical across both parts. Pin-to-pin compatibility and board-level footprint placement require no adjustment between these components.
