Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD15FC821JO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 820 pF (exact match required)
• Tolerance: ±5% (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: 0.232" / 5.90 mm (exact match required)
• Series: CD15 (exact match required)

Substitute parts must satisfy all parameters listed above to ensure functional and mechanical compatibility without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

CD15FC821JO3F qualifies as a parametric equivalent and direct substitute for CD15FC821JO3 based on complete electrical and mechanical parameter alignment across all critical specifications.

Compliance Considerations:

The CD15FC821JO3F provides enhanced regulatory compliance status relative to the primary part:

• RoHS Compliance: CD15FC821JO3F achieves ROHS3 compliance, whereas CD15FC821JO3 is RoHS non-compliant. Selection of CD15FC821JO3F is required for applications subject to RoHS3 regulatory requirements.
• REACH Status: CD15FC821JO3F is REACH Unaffected, compared to CD15FC821JO3 which is REACH Affected. Applications requiring REACH compliance should specify CD15FC821JO3F.

Inventory Availability:

CD15FC821JO3F maintains higher inventory availability (1899 units) relative to CD15FC821JO3 (694 units), supporting improved supply chain continuity for high-volume procurement scenarios.

Selection Criteria:

• Use CD15FC821JO3F for new designs or applications requiring RoHS3 and REACH compliance.
• Use CD15FC821JO3 where legacy component specifications or existing design documentation explicitly requires the non-compliant variant.
• Both parts are electrically and mechanically interchangeable without circuit modification or PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can CD15FC821JO3F be used as a direct replacement for CD15FC821JO3 in existing designs?

A: Yes. CD15FC821JO3F is a parametric equivalent with identical electrical and mechanical specifications. Direct substitution is possible without circuit modification, PCB layout changes, or performance degradation.
