CMR04F161JPDM Equivalent & Substitute Parts

Part Overview

The CMR04F161JPDM is a 160 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 500 V operation in radial through-hole configuration. This component is classified as Active product status and is suitable for general-purpose applications requiring stable capacitance and high voltage performance. Mica dielectric capacitors are selected for applications demanding low loss, excellent frequency stability, and reliable performance across extended temperature ranges. Substitute parts are identified when inventory constraints, lead time requirements, or procurement preferences necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the CMR04F161JPDM are identified based on strict parametric equivalence. The following electrical and mechanical parameters must match identically for a part to qualify as a direct substitute:

• Capacitance value: 160 pF
• Tolerance: ±5%
• Voltage rating: 500 V
• Dielectric material: Mica
• Operating temperature range: -55°C ~ 150°C
• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.150" (3.80mm)
• Physical dimensions: 0.382" L x 0.209" W (9.70mm x 5.30mm)
• Maximum seated height: 0.358" (9.10mm)
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The CMR04F161JPDR meets all these criteria and is classified as a parametric equivalent. Both parts belong to the CMR series from Cornell Dubilier Electronics and maintain identical electrical performance and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the CMR04F161JPDM and CMR04F161JPDR are Active status components manufactured by Cornell Dubilier Electronics and carry identical electrical and mechanical specifications. Selection between these parts is based on availability and procurement logistics rather than technical performance differences.

The CMR04F161JPDR currently maintains higher inventory availability (967 pieces versus 860 pieces), which may provide advantages for high-volume production runs or time-sensitive procurement scenarios. Both parts satisfy ROHS3 compliance requirements and REACH unaffected status, making them suitable for applications subject to environmental and regulatory restrictions.

The radial through-hole configuration with 0.150" (3.80mm) lead spacing ensures direct PCB compatibility without modification to existing board layouts. The mica dielectric construction provides stable capacitance performance across the full operating temperature range of -55°C to 150°C, with MSL rating of 1 (Unlimited) indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can CMR04F161JPDR be used as a direct replacement for CMR04F161JPDM?

A: Yes. Both parts are parametric equivalents with identical capacitance (160 pF), voltage rating (500 V), tolerance (±5%), dielectric material (Mica), operating temperature range (-55°C ~ 150°C), and physical dimensions. They are interchangeable in all applications where the CMR04F161JPDM is specified.

Q: Are there any differences in lead spacing or PCB footprint between these parts?

A: No. Both parts feature identical lead spacing of 0.150" (3.80mm) and physical dimensions of 0.382" L x 0.209" W (9.70mm x 5.30mm). PCB layouts designed for one part accommodate the other without modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CMR04F161JPDM and CMR04F161JPDR are ROHS3 Compliant and REACH Unaffected, satisfying identical regulatory requirements for environmental and hazardous substance restrictions.

Q: What is the significance of the MSL rating of 1 (Unlimited)?

A: MSL 1 (Unlimited) indicates that these mica capacitors have no moisture sensitivity limitations. They do not require special dry-pack storage, desiccant handling, or bake-out procedures prior to soldering, simplifying inventory management and assembly processes.

Q: Are these parts suitable for high-frequency applications?

A: The provided specifications confirm mica dielectric construction and general-purpose classification. Specific frequency response characteristics are not included in the available parameters and should be verified against detailed datasheets for frequency-dependent applications.

Q: What is the difference between the CMR series designation and other capacitor series?

A: The CMR series designation indicates the product line from Cornell Dubilier Electronics. Both substitute parts belong to the same CMR series, ensuring consistency in manufacturing standards and performance characteristics.
