CMR06F472JPDR Mica Capacitor - Equivalent & Substitute Parts

Part Overview

The CMR06F472JPDR is a 4700 pF mica capacitor rated for 500 V operation, manufactured by Cornell Dubilier Electronics (CDE) in the CMR series. This component is classified as Active and designed for general-purpose applications requiring high voltage and temperature stability. Mica capacitors are essential in circuits demanding low losses, stable capacitance over temperature, and high reliability in demanding environments. Alternative equivalent parts may be required due to inventory constraints, supply chain optimization, or design revision specifications.

Key Parameters

Substitute Part Grouping Explanation

The CMR06F472JPDM is established as a parametric equivalent based on identical electrical and mechanical specifications. Substitution validity is determined by compliance with the following critical parameters:

Electrical Parameters:

• Capacitance value: 4700 pF
• Capacitance tolerance: ±5%
• Voltage rating: 500 V minimum
• Dielectric material: Mica

Mechanical Parameters:

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.350" (8.90 mm)
• Height seated maximum: 0.579" (14.70 mm)

Environmental & Compliance Parameters:

• Operating temperature range: -55°C to 150°C minimum
• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

Parts matching all of these parameters are functionally interchangeable at the board level without design modifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CMR06F472JPDR and CMR06F472JPDM are Active status components manufactured by Cornell Dubilier Electronics, maintaining identical compliance certifications including ROHS3 and REACH Unaffected designations. Selection between these parts is based on availability and sourcing logistics. The CMR06F472JPDM currently maintains higher inventory availability (1016 units) relative to the CMR06F472JPDR (752 units), supporting supply chain continuity. Both components are suitable for production deployment without requiring design or qualification modifications, as they satisfy all electrical, mechanical, environmental, and regulatory requirements identically.

Frequently Asked Questions (FAQ)

Q: Can the CMR06F472JPDM be used as a direct replacement for the CMR06F472JPDR in existing designs?

A: Yes. The CMR06F472JPDM is a parametric equivalent with identical electrical specifications (4700 pF at ±5% tolerance, 500 V rating), mechanical configuration (0.350" lead spacing, radial through-hole package), and environmental ratings (-55°C to 150°C operating range). No circuit modifications or re-qualification are required.

Q: What distinguishes these two part numbers if all specifications are identical?

A: The difference is limited to the last two characters of the part number designation (DR versus DM), which typically indicates manufacturing lot or packaging revision within the same product family. All electrical and mechanical parameters remain identical.

Q: Are there compliance differences between these substitute parts?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, MSL Level 1 (Unlimited), and EAR99 ECCN classification.

Q: What is the minimum voltage requirement for substitution?

A: The rated voltage for both parts is 500 V. Substitution is valid only when the application voltage does not exceed 500 V.

Q: Are there any temperature range restrictions?

A: Both parts operate within -55°C to 150°C. Substitution is valid only when the application operating temperature falls within this range.

Q: Why might one part number be preferred over another from a supply chain perspective?

A: Inventory levels may differ. Current availability shows CMR06F472JPDM at 1016 units and CMR06F472JPDR at 752 units. Selection should prioritize the part with adequate inventory for production requirements.
