CM05CD070DO3 Mica Capacitor Equivalent & Substitute Parts

Part Overview

The CM05CD070DO3 is a 7 pF mica capacitor rated for 500 V operation in a radial through-hole package, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and is suitable for general-purpose applications requiring high-voltage, low-capacitance filtering and coupling functions.

Substitute parts become necessary when the original CM05CD070DO3 series reaches end-of-life status, inventory depletion occurs, or when design requirements mandate compliance with updated regulatory standards such as RoHS3 certification or REACH unaffected status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CM05CD070DO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance value: 7 pF
• Capacitance tolerance: ±0.5 pF
• Voltage rating: 500 V
• Dielectric material: Mica

Mechanical Parameters (Non-Negotiable):

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.232" (5.90 mm)
• Physical dimensions: 0.449" L x 0.169" W (11.40 mm x 4.30 mm)
• Maximum seated height: 0.358" (9.10 mm)

Operational Parameters (Non-Negotiable):

• Operating temperature range: -55°C to 125°C

All substitute parts listed below maintain identical electrical, mechanical, and operational specifications. Variations in regulatory compliance status (RoHS, REACH) and moisture sensitivity classification do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

CM05CD070DO3 (Original Part): Select this part when existing designs are locked to the CM05 series designation and regulatory compliance status is not a constraint. Current inventory of 853 pieces supports immediate procurement for active production.

CD15CD070DO3 (Parametric Equivalent): This substitute maintains identical electrical and mechanical specifications with equivalent regulatory status. The CD15 series represents a direct functional replacement. Inventory of 910 pieces provides adequate supply. Use this part when CM05CD070DO3 availability becomes limited and RoHS3 compliance is not required.

CD15CD070DO3F (Recommended Substitute for Compliance-Driven Applications): This part is the preferred substitute when designs require RoHS3 compliance or REACH unaffected status. All electrical and mechanical parameters remain identical to the original CM05CD070DO3. The CD15CD070DO3F carries the highest inventory level at 3176 pieces, ensuring long-term supply chain stability. This part is suitable for new designs or redesigns targeting modern regulatory requirements.

Selection between CD15CD070DO3 and CD15CD070DO3F depends solely on regulatory compliance mandates for the end application. Both are functionally equivalent to CM05CD070DO3.

Frequently Asked Questions (FAQ)

Q: Can CD15CD070DO3 and CD15CD070DO3F be used interchangeably with CM05CD070DO3?

A: Yes. All three parts share identical capacitance (7 pF), tolerance (±0.5 pF), 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" / 5.90 mm), and physical dimensions. They are functionally equivalent for circuit applications.

Q: What is the difference between CD15CD070DO3 and CD15CD070DO3F?

A: The primary differences are regulatory compliance status and moisture sensitivity classification. CD15CD070DO3F is RoHS3 compliant and REACH unaffected, while CD15CD070DO3 is RoHS non-compliant and REACH affected. Both maintain identical electrical and mechanical specifications. CD15CD070DO3F is recommended for applications requiring modern regulatory compliance.

Q: Will substituting these parts require PCB layout changes?

A: No. All substitute parts maintain identical lead spacing (0.232" / 5.90 mm), physical dimensions (0.449" L x 0.169" W), and maximum seated height (0.358" / 9.10 mm). Direct board-level substitution is possible without layout modification.

Q: Are there any temperature or voltage derating considerations when using substitute parts?

A: No. All parts operate across the identical temperature range (-55°C to 125°C) and carry the same 500 V voltage rating. Operating conditions remain unchanged.

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

A: CD15CD070DO3F is the recommended choice for new designs due to RoHS3 compliance and REACH unaffected status, combined with the highest inventory availability (3176 pieces). This ensures regulatory alignment and supply chain continuity.

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

A: Substitution eligibility is determined by the parameters provided in this reference. Frequency-dependent performance characteristics are not included in the specification data and must be evaluated against detailed application requirements.
