Substitute Part Grouping Explanation

Substitution eligibility for the CD42FC683FO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.068 µF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage Rating: 300 V (exact match required)
• Dielectric Material: Mica (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: Radial (exact match required)
• Lead Spacing: 1.063" / 27.00 mm (exact match required)
• Physical Dimensions: 1.480" L × 0.469" W / 37.60 mm × 11.90 mm (exact match required)

The identified substitute part CD42FC683FO3F maintains complete electrical and mechanical compatibility with the primary part number. Differences in RoHS compliance status and REACH classification do not affect functional substitution but may influence procurement decisions based on regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

CD42FC683FO3F is a direct functional equivalent to CD42FC683FO3 for all electrical and mechanical applications. Selection between these two part numbers should be based on regulatory and compliance requirements:

• CD42FC683FO3: Select when RoHS non-compliant components are acceptable and REACH-affected materials are permitted by design specifications or regional regulations.

• CD42FC683FO3F: Select when ROHS3 compliance is required or when REACH-unaffected status is mandated by procurement specifications, customer requirements, or end-market regulations.

Both parts are active products with current manufacturing status. Inventory availability (722 pcs for CD42FC683FO3; 846 pcs for CD42FC683FO3F) may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can CD42FC683FO3F replace CD42FC683FO3 in existing circuit designs?

A: Yes. CD42FC683FO3F is a direct substitute with identical electrical characteristics (0.068 µF, ±1%, 300 V), dielectric material (mica), operating temperature range (-55°C to 125°C), and mechanical specifications (through-hole radial, 1.063" lead spacing, 37.60 mm × 11.90 mm dimensions). No circuit modifications are required.

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

A: The primary differences are compliance certifications. CD42FC683FO3F is ROHS3 compliant and REACH unaffected, while CD42FC683FO3 is RoHS non-compliant and REACH affected. All functional and physical parameters are identical.

Q: Will the physical footprint be the same on the PCB?

A: Yes. Both parts have identical lead spacing (1.063" / 27.00 mm), body dimensions (1.480" L × 0.469" W / 37.60 mm × 11.90 mm), and seated height (0.921" / 23.40 mm). PCB layout and hole spacing require no modification.

Q: Which part should I specify for new designs?

A: Specify CD42FC683FO3F for new designs if ROHS3 compliance or REACH-unaffected status is required by your application, customer, or regional market. Both parts are active and in production.

Q: Are there any performance differences between these parts?

A: No. Both parts are manufactured by Cornell Dubilier Electronics in the CD42 series with identical capacitance, tolerance, voltage rating, temperature range, and dielectric material. Performance is equivalent.
