Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD15FD501JO3 is determined by matching the following critical parameters:

• Capacitance: 500 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 500 V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Mica (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.232" (5.90 mm) (exact match required for PCB compatibility)
• Operating Temperature Range: -55°C to 125°C (exact match required)

The CD15FD501JO3F meets all substitution criteria while offering enhanced compliance status relative to the original part number.

Parameter Comparison

Engineering Selection Recommendations

The CD15FD501JO3F qualifies as a direct substitute for the CD15FD501JO3 based on identical electrical and mechanical specifications. The substitution is supported by the following factors:

Compliance Advantages: The CD15FD501JO3F carries ROHS3 compliance and REACH Unaffected status, compared to the original part's RoHS non-compliance and REACH Affected designation. For applications with regulatory compliance mandates, the substitute part addresses these requirements without modification to circuit design.

Product Status: Both parts maintain active product status within the CD15 series, confirming ongoing manufacturing support and availability.

Inventory Availability: The CD15FD501JO3F demonstrates significantly higher inventory levels (13,243 pieces) relative to the original part (1,039 pieces), supporting consistent supply chain performance for high-volume procurement.

Frequently Asked Questions (FAQ)

Q: Are the CD15FD501JO3 and CD15FD501JO3F mechanically interchangeable?

A: Yes. Both parts share identical package dimensions (0.469" L x 0.220" W), lead spacing (0.232" or 5.90 mm), and seated height (0.402" maximum). No PCB layout modifications are required for substitution.

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

A: The CD15FD501JO3F provides ROHS3 compliance and REACH Unaffected status, while the CD15FD501JO3 is RoHS non-compliant and REACH Affected. Electrical and thermal specifications remain identical.

Q: Can the CD15FD501JO3F be used in applications originally designed for the CD15FD501JO3?

A: Yes, without design revision. All critical parameters—capacitance, tolerance, voltage rating, operating temperature range, and physical dimensions—are identical, supporting one-to-one substitution in existing designs.

Q: Does the substitution affect regulatory certification?

A: The CD15FD501JO3F's ROHS3 compliance and REACH Unaffected status may improve regulatory certification outcomes for applications subject to these standards. No additional design verification is required for this substitution.

Q: Why does the substitute part number include an additional letter designation?

A: The "F" suffix in CD15FD501JO3F indicates compliance with ROHS3 and REACH requirements while maintaining the same electrical and physical specifications as the base part number CD15FD501JO3.
