CM05CD120JO3 Equivalent & Substitute Parts

Part Overview

The CM05CD120JO3 is a 12 pF mica capacitor rated for 500 V operation, manufactured by Cornell Dubilier Electronics (CDE). This through-hole radial component is designed for general-purpose applications requiring high voltage performance and stable capacitance characteristics across the operating temperature range of -55°C to 125°C. The part is currently active in production with 704 units in stock.

Equivalent and substitute parts are necessary when the original CM05CD120JO3 becomes unavailable, when alternative compliance certifications are required, or when design revisions necessitate component standardization across product lines. The substitute parts listed maintain identical electrical and mechanical specifications while offering different series designations and compliance profiles.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CM05CD120JO3 is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance Value: 12 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 to 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: 0.449" L x 0.169" W, Height 0.358" max (exact match required)

The substitute parts CD15CD120JO3 and CD15CD120JO3F are classified as parametric equivalents because they satisfy all electrical and mechanical requirements. The primary differences between these parts relate to series designation (CD15 versus CM05) and compliance certifications (RoHS and REACH status), which do not affect functional interchangeability in applications where the original specifications are met.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CM05CD120JO3, CD15CD120JO3, and CD15CD120JO3F—are functionally equivalent for applications requiring a 12 pF, 500 V mica capacitor with radial through-hole mounting.

CM05CD120JO3 is the primary part specification. It is active in production with adequate inventory availability.

CD15CD120JO3 is a direct parametric equivalent from the CD15 series. It maintains identical electrical and mechanical specifications and is active in production. This part is RoHS non-compliant and REACH Affected, matching the compliance profile of the CM05CD120JO3. Inventory availability is higher at 939 units.

CD15CD120JO3F is a parametric equivalent with enhanced compliance certifications. It is ROHS3 Compliant and REACH Unaffected, making it suitable for applications with stricter regulatory requirements. This part is active in production with the highest inventory availability at 1598 units.

Selection between these parts depends on compliance requirements. For applications without RoHS3 or REACH compliance mandates, CM05CD120JO3 or CD15CD120JO3 are appropriate. For applications requiring ROHS3 compliance and REACH exemption, CD15CD120JO3F is the specified choice.

Frequently Asked Questions (FAQ)

Q: Can CM05CD120JO3 be replaced with CD15CD120JO3?

A: Yes. Both parts are parametric equivalents with identical capacitance (12 pF), tolerance (±5%), voltage rating (500 V), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (radial), lead spacing (0.232"), and physical dimensions. The primary difference is the series designation (CM05 versus CD15) and compliance certifications. Functional interchangeability is complete.

Q: What is the difference between CD15CD120JO3 and CD15CD120JO3F?

A: Both parts are from the CD15 series with identical electrical and mechanical specifications. The primary difference is compliance certification. CD15CD120JO3 is RoHS non-compliant and REACH Affected. CD15CD120JO3F is ROHS3 Compliant and REACH Unaffected. Selection depends on regulatory requirements for the end application.

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

A: Yes. All three parts share identical dimensions: 0.449" length x 0.169" width (11.40mm x 4.30mm), with a maximum seated height of 0.358" (9.10mm). Lead spacing is 0.232" (5.90mm) for all parts. PCB layout and mechanical fit are interchangeable.

Q: Which part should be selected for new designs?

A: For new designs without RoHS3 compliance requirements, CM05CD120JO3 or CD15CD120JO3 are acceptable. For new designs requiring ROHS3 compliance and REACH exemption, CD15CD120JO3F is the specified selection. All parts are active in production.

Q: Is there a difference in operating temperature performance?

A: No. All three parts operate across the identical temperature range of -55°C to 125°C with the same mica dielectric material and general-purpose design.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes, provided the assembly does not have specific compliance documentation that restricts part selection. The identical lead spacing, physical dimensions, and electrical specifications ensure mechanical and functional interchangeability. Compliance certifications should be verified against assembly-level requirements.
