Substitute Part Grouping Explanation

Substitution of the CD30FD103FO3 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CD30FD103FO3F maintains identical specifications for capacitance (10000 pF), tolerance (±1%), rated voltage (500V), dielectric material (Mica), mounting type (Through Hole), package configuration (Radial), lead spacing (0.437" / 11.10mm), and operating temperature range (-55°C to 125°C). Both parts belong to the CD30 series and are classified as general-purpose components.

The primary distinction between these parts is their compliance status. The CD30FD103FO3F variant incorporates RoHS3 compliance and REACH unaffected status, whereas the original CD30FD103FO3 is RoHS non-compliant and REACH affected. This difference makes the substitute part suitable for applications and regions with stricter environmental and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Selection between CD30FD103FO3 and CD30FD103FO3F should be based on regulatory and compliance requirements applicable to the end application.

CD30FD103FO3 is suitable for applications where RoHS and REACH compliance are not mandated or where legacy component specifications are acceptable. This variant offers established supply availability with 916 units in stock.

CD30FD103FO3F is the appropriate choice for applications subject to RoHS3 regulations or REACH compliance requirements. This variant carries RoHS3 compliant certification and REACH unaffected status, making it suitable for European markets and applications with strict environmental standards. Current inventory of 974 units supports consistent supply.

Both parts are electrically and mechanically identical, ensuring direct interchangeability in circuit design and PCB layout without modification to schematic or board files.

Frequently Asked Questions (FAQ)

Q: Are CD30FD103FO3 and CD30FD103FO3F electrically identical?
