CM05FD101JO3 Equivalent & Substitute Parts

Part Overview

The CM05FD101JO3 is a 100 pF mica capacitor rated for 500 V operation, manufactured by Cornell Dubilier Electronics (CDE) in the CM05 series. This through-hole radial component is designed for general-purpose applications requiring high voltage stability and precision capacitance values. The part is currently active in production with 858 units in stock.

Substitute parts are necessary when the original CM05FD101JO3 becomes unavailable, when alternative compliance certifications are required, or when inventory constraints necessitate sourcing from equivalent product lines within the same manufacturer's portfolio.

Substitute Part Grouping Explanation

Substitution of the CM05FD101JO3 is determined by strict equivalence across the following critical parameters:

Capacitance Value: 100 pF (exact match required)
Tolerance: ±5% (exact match required)
Voltage Rating: 500 V (exact match required)
Dielectric Material: Mica (exact match required)
Operating Temperature Range: -55°C ~ 125°C (exact match required)
Mounting Type: Through Hole (exact match required)
Package Configuration: Radial (exact match required)
Lead Spacing: 0.232" (5.90mm) (exact match required)
Physical Dimensions: 0.461" L x 0.181" W, Height 0.358" max (exact match required)

The substitute parts CD15FD101JO3 and CD15FD101JO3F meet all electrical and mechanical parameters. Both are manufactured by Cornell Dubilier Electronics and belong to the CD15 series. Differences exist only in compliance certifications and moisture sensitivity classifications, which do not affect functional equivalence for component selection purposes.

Engineering Selection Recommendations

CM05FD101JO3: Select this part when the original specification requires RoHS non-compliant components and REACH-affected materials are acceptable for the application. This part maintains the CM05 series designation and is suitable for legacy designs or applications without regulatory compliance constraints.

CD15FD101JO3: This substitute provides identical electrical and mechanical performance to the CM05FD101JO3 while maintaining RoHS non-compliant status. The CD15 series offers higher inventory availability (1398 units) and is suitable for applications where REACH-affected status is permissible.

CD15FD101JO3F: This substitute is the preferred selection for applications requiring ROHS3 compliance and REACH-unaffected material status. All electrical and mechanical parameters remain identical to the original CM05FD101JO3. This part is recommended for new designs, regulated industries, or applications with environmental compliance requirements.

All three parts are manufactured by Cornell Dubilier Electronics and are currently active in production.

Frequently Asked Questions (FAQ)

Q: Can CD15FD101JO3 and CD15FD101JO3F be used interchangeably with CM05FD101JO3?

A: Yes, both substitute parts are electrically and mechanically equivalent. The CD15FD101JO3 and CD15FD101JO3F differ only in compliance certifications (RoHS and REACH status), not in functional performance. Selection depends on regulatory requirements for the end application.

Q: What is the difference between CD15FD101JO3 and CD15FD101JO3F?

A: Both parts have identical capacitance, voltage rating, tolerance, temperature range, and physical dimensions. CD15FD101JO3F is ROHS3 compliant and REACH unaffected, while CD15FD101JO3 is RoHS non-compliant and REACH affected. Choose CD15FD101JO3F for applications requiring environmental compliance.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share identical lead spacing (0.232" / 5.90mm), body dimensions (0.461" L x 0.181" W / 11.70mm x 4.60mm), and maximum seated height (0.358" / 9.10mm). They are directly interchangeable in through-hole PCB layouts.

Q: What is the operating temperature range for these capacitors?

A: All three parts operate across -55°C to 125°C, providing stable performance across industrial and commercial temperature ranges.

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