Substitute Part Grouping Explanation

Substitution of the CD10CDO30DO3F is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CD10CD030DO3F qualifies as a parametric equivalent because it maintains identical specifications in the following key areas:

Electrical Parameters (Must Match Exactly):

• Capacitance value: 3 pF
• Tolerance: ±0.5 pF
• Voltage rating: 500 V
• Dielectric material: Mica

Mechanical Parameters (Must Match Exactly):

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.142" (3.60 mm)
• Operating temperature range: -55°C to 125°C

Compliance & Status (Must Match Exactly):

• RoHS3 Compliant
• REACH Unaffected
• Active product status

The only permitted variation between the main part and substitute is packaging format (Bulk versus standard packaging) and minor dimensional tolerance in length (0.358" versus 0.360"), which does not affect PCB assembly or electrical performance.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can CD10CD030DO3F be used as a direct replacement for CD10CDO30DO3F?

A: Yes. Both parts are parametric equivalents with identical capacitance (3 pF), tolerance (±0.5 pF), voltage rating (500 V), dielectric material (Mica), mounting type (Through Hole), package configuration (Radial), lead spacing (0.142" / 3.60 mm), and operating temperature range (-55°C to 125°C). The parts are electrically and mechanically interchangeable.

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

A: The primary difference is packaging format. CD10CDO30DO3F uses standard packaging, while CD10CD030DO3F uses Bulk packaging. Additionally, the length dimension varies slightly (0.358" versus 0.360"), which is within normal manufacturing tolerance and does not affect PCB assembly or performance.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both CD10CDO30DO3F and CD10CD030DO3F are RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

Q: Will the slight difference in length (0.358" versus 0.360") affect PCB assembly?

A: No. The 0.002" (0.05 mm) difference in length is within standard manufacturing tolerance for radial through-hole capacitors and does not affect PCB hole pattern compatibility, lead spacing, or assembly processes.

Q: Are both parts currently available?

A: Yes. Both parts maintain Active product status. CD10CDO30DO3F has 664 pieces in stock, and CD10CD030DO3F has 981 pieces in stock.

Q: Can I mix these parts in the same design?

A: Yes. Since both parts are parametric equivalents with identical electrical and mechanical specifications, they can be used interchangeably within the same circuit design without any performance impact.

Q: What is the lead spacing for PCB layout purposes?

A: The lead spacing is 0.142 inches (3.60 mm) for both parts. This dimension determines the PCB hole pattern and must be matched during board design.
