Key Parameters

Substitute Part Grouping Explanation

The CM04FD131FO3 qualifies as a parametric equivalent to the CD10FD131FO3 based on the following critical electrical and mechanical parameters:

Electrical Equivalence:

• Capacitance: 130 pF (identical)
• Tolerance: ±1% (identical)
• Voltage Rating: 500 V (identical)
• Dielectric Material: Mica (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)

Mechanical Equivalence:

• Mounting Type: Through Hole (identical)
• Package Type: Radial (identical)
• Lead Spacing: 0.142" (3.60 mm) (identical)
• Physical Dimensions: 0.382" L x 0.201" W, Height 0.358" max (identical)

The substitution is valid across both product lines, with both components meeting the same electrical specifications and physical form factor requirements for direct board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

Both the CD10FD131FO3 and CM04FD131FO3 are active products with full availability status. Component selection between these two parts may be determined by:

1. Supply Chain Availability: Both components are in active stock with comparable inventory levels (709 units for CD10FD131FO3; 927 units for CM04FD131FO3).

2. Regulatory Compliance: Both parts are REACH Affected and carry EAR99 classification, requiring equivalent compliance documentation in export or regulated applications.

3. Design Integration: Since both parts share identical electrical specifications, physical dimensions, and mounting characteristics, either part can be selected without design modifications or board redesign.

4. Moisture Sensitivity Considerations: The CM04FD131FO3 is rated at MSL 1 (Unlimited), indicating superior moisture resistance characteristics compared to the CD10FD131FO3 (Not Applicable classification).

Frequently Asked Questions (FAQ)

Q: Can the CM04FD131FO3 be used as a direct replacement for the CD10FD131FO3? A: Yes. Both components are identical in capacitance (130 pF), voltage rating (500 V), tolerance (±1%), dielectric material (Mica), operating temperature range (-55°C ~ 125°C), and physical dimensions. Direct substitution is valid without circuit or board redesign.

Q: Are there differences in lead spacing or mounting footprint? A: No. Both parts have identical lead spacing of 0.142" (3.60 mm) and radial through-hole mounting configuration. PCB layout footprints are identical.

Q: What is the difference between the CD10 and CM04 series designations? A: The series designation reflects the internal product line categorization within Cornell Dubilier Electronics. Both series employ identical mica dielectric technology and manufacturing standards. The series difference does not affect electrical performance or mechanical compatibility.

Q: Are there compliance or regulatory differences between these parts? A: Both parts carry REACH Affected status and EAR99 classification. Compliance requirements remain equivalent across both components. Moisture Sensitivity Level (MSL) differs, with CM04FD131FO3 rated at MSL 1 (Unlimited) versus CD10FD131FO3 rated as Not Applicable.

Q: What inventory considerations should influence part selection? A: The CM04FD131FO3 has higher current inventory (927 units) compared to the CD10FD131FO3 (709 units). For applications prioritizing immediate stock availability, the CM04FD131FO3 offers supply chain advantage without electrical or mechanical compromise.

Q: Can these components be used interchangeably in existing designs? A: Yes. Existing designs using the CD10FD131FO3 can be revised to use the CM04FD131FO3 without modifications to schematic symbols, PCB layouts, or design calculations. Both parts meet identical functional requirements.
