CM05ED240JO3 Equivalent & Substitute Parts

Part Overview

The CM05ED240JO3 is a 24 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 1086 units in stock.

Equivalent substitute parts are necessary when the CM05ED240JO3 becomes unavailable, when design revisions require updated compliance certifications, or when inventory constraints require sourcing from alternative production batches within the same manufacturer's portfolio.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CM05ED240JO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-negotiable):

• Capacitance: 24 pF
• Tolerance: ±5%
• Voltage Rating: 500 V
• Dielectric Material: Mica

Mechanical Parameters (Non-negotiable):

• Mounting Type: Through Hole
• Package Configuration: Radial
• Lead Spacing: 0.232" (5.90mm)
• Physical Dimensions: 0.449" L x 0.169" W (11.40mm x 4.30mm)
• Maximum Seated Height: 0.358" (9.10mm)

Operational Parameters (Non-negotiable):

• Operating Temperature Range: -55°C ~ 125°C

All substitute parts listed below meet these criteria without exception. Compliance certifications (RoHS, REACH) and packaging configurations may vary and are noted separately.

Parameter Comparison

Engineering Selection Recommendations

CM05ED240JO3 (Original Part): Use when existing designs are locked to this specific part number and RoHS non-compliance is acceptable for the application. Current inventory of 1086 units supports immediate availability.

CD15ED240JO3 (Parametric Equivalent): Use as a direct substitute when the CM05ED240JO3 becomes unavailable. This part maintains identical electrical and mechanical specifications. RoHS non-compliance status matches the original part. Higher inventory (1614 units) provides extended supply security. REACH Affected status is equivalent to the original part.

CD15ED240JO3F (Parametric Equivalent with Enhanced Compliance): Use when design requirements mandate ROHS3 compliance or REACH Unaffected status. This part is functionally and mechanically identical to CM05ED240JO3 and CD15ED240JO3 but incorporates updated regulatory compliance certifications. Inventory of 1530 units ensures availability. This variant is suitable for new designs or design revisions targeting current regulatory standards.

All three parts are manufactured by Cornell Dubilier Electronics and share identical electrical performance, temperature range, and mechanical form factor.

Frequently Asked Questions (FAQ)

Q: Can CD15ED240JO3 be used as a direct replacement for CM05ED240JO3 in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical. They share the same capacitance (24 pF), tolerance (±5%), voltage rating (500 V), operating temperature range (-55°C ~ 125°C), and physical dimensions. The radial lead spacing (0.232" / 5.90mm) and through-hole mounting configuration are identical, allowing direct PCB substitution without layout modifications.

Q: What is the difference between CD15ED240JO3 and CD15ED240JO3F?

A: The parts are electrically and mechanically identical. The primary difference is regulatory compliance: CD15ED240JO3F is ROHS3 Compliant and REACH Unaffected, while CD15ED240JO3 is RoHS non-compliant and REACH Affected. Select CD15ED240JO3F for applications requiring current environmental compliance certifications.

Q: Are there any physical dimension differences between these three parts?

A: No. All three parts share identical physical dimensions: 0.449" L x 0.169" W (11.40mm x 4.30mm) with a maximum seated height of 0.358" (9.10mm). Lead spacing is 0.232" (5.90mm) for all variants. They are mechanically interchangeable on PCBs designed for radial through-hole mica capacitors.

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

A: CD15ED240JO3F is the recommended choice for new designs. It provides ROHS3 compliance and REACH Unaffected status, aligning with current regulatory requirements. Electrical and mechanical performance is identical to the other variants.

Q: Can these parts be used interchangeably in high-voltage applications?

A: Yes. All three parts are rated for 500 V operation and are suitable for high-voltage applications within this rating. The mica dielectric material provides stable performance across the full operating temperature range of -55°C ~ 125°C.

Q: What is the lead spacing tolerance for these radial capacitors?

A: The specified lead spacing is 0.232" (5.90mm). This dimension is consistent across all three part numbers and determines PCB hole pattern compatibility.
