• Capacitance Value: 100 pF (identical across all parts)
• Tolerance: ±1% (identical across all parts)
• Voltage Rating: 500 V (identical across all parts)
• Dielectric Material: Mica (identical across all parts)
• Operating Temperature Range: -55°C to 125°C (identical across all parts)
• Mounting Type: Through Hole (identical across all parts)
• Package Configuration: Radial (identical across all parts)
• Lead Spacing: 0.232" (5.90 mm) (identical across all parts)
• Physical Footprint: 0.461" L × 0.181" W, Height 0.358" max (identical across all parts)

All substitute parts maintain full functional and mechanical compatibility with the original CM05FD101FO3.

Parameter Comparison

Engineering Selection Recommendations

CM05FD101FO3 to CD15FD101FO3: This substitution is valid for applications where RoHS non-compliance is acceptable. Both parts share identical electrical and mechanical specifications with full pin-to-pin compatibility.

CM05FD101FO3 to CD15FD101FO3F: This substitution is recommended for designs requiring ROHS3 compliance and REACH unaffected status. The CD15FD101FO3F maintains all electrical and mechanical parameters identical to the original part while offering improved regulatory compliance.

All substitute parts maintain Active product status, ensuring long-term availability and support for production applications.

Frequently Asked Questions (FAQ)

Q: Are the CM05FD101FO3 and CD15FD101FO3 substitutes fully interchangeable?

A: Yes. Both parts are identical in capacitance (100 pF), tolerance (±1%), voltage rating (500 V), dielectric material (Mica), operating temperature range (-55°C to 125°C), mounting configuration (Through Hole Radial), lead spacing (0.232"), and physical dimensions (0.461" L × 0.181" W, 0.358" height max). Direct board-level substitution is valid without design modifications.

Q: What is the primary difference between CD15FD101FO3 and CD15FD101FO3F?

A: The primary differences are regulatory compliance attributes. CD15FD101FO3F is ROHS3 compliant and REACH unaffected, while CD15FD101FO3 is RoHS non-compliant and REACH affected. Electrical and mechanical specifications are identical.

Q: Which substitute part should be selected for new designs?

A: CD15FD101FO3F is the appropriate selection for new designs, as it provides ROHS3 compliance and REACH unaffected status, aligning with current regulatory requirements.

Q: Will substituting these parts require PCB redesign or re-qualification?

A: No. The identical lead spacing (0.232"), physical footprint (0.461" L × 0.181" W), and mounting configuration (Through Hole Radial) eliminate PCB redesign requirements. Functional performance remains unchanged across all three part numbers.

Q: Are inventory levels a consideration in part selection?

A: Inventory availability may influence procurement decisions. CD15FD101FO3F maintains the highest current inventory (7009 pieces), followed by CD15FD101FO3 (1369 pieces), and CM05FD101FO3 (1063 pieces).
