Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMR05F131FPDP is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value (130 pF), tolerance specification (±1%), and voltage rating (500 V) must match exactly. The mica dielectric material is a defining characteristic of this component class and cannot be substituted with alternative dielectric types.

Mechanical Parameters: Mounting configuration (through-hole radial), lead spacing (0.224" / 5.70 mm), and physical envelope dimensions (0.461" L × 0.181" W × 0.370" H maximum) must be identical to ensure PCB compatibility without design modification.

Environmental & Compliance Parameters: Operating temperature range (-55°C to 150°C), RoHS3 compliance status, and REACH classification must be maintained. Moisture sensitivity level (MSL 1) indicates unlimited shelf life without special handling requirements.

Only parts meeting all specified parameters across these three categories qualify as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The CMR05F131FPDR qualifies as a direct parametric equivalent to the CMR05F131FPDP. Both components are manufactured by Cornell Dubilier Electronics within the CMR series and maintain identical electrical, mechanical, and environmental specifications. Both parts carry Active product status with full RoHS3 compliance and REACH unaffected classification, confirming regulatory alignment for current and future applications.

Selection between these two part numbers may be based on inventory availability and supply chain considerations. The CMR05F131FPDR currently maintains higher inventory levels (1096 pieces versus 908 pieces), which may influence procurement decisions for high-volume production requirements or extended lead-time mitigation strategies.

Frequently Asked Questions (FAQ)

Q: Can CMR05F131FPDR be used as a direct replacement for CMR05F131FPDP in existing circuit designs?

A: Yes. Both parts are parametrically identical across all electrical specifications (130 pF, ±1%, 500 V), mechanical dimensions (0.461" L × 0.181" W, 0.224" lead spacing), and environmental ratings (-55°C to 150°C). No circuit redesign or PCB layout modification is required.

Q: Are there any compliance or regulatory differences between these two part numbers?

A: No. Both CMR05F131FPDP and CMR05F131FPDR maintain identical RoHS3 compliance status and REACH unaffected classification. Both parts are suitable for applications subject to these regulatory frameworks.

Q: What does the difference in part number suffix (FPDP versus FPDR) indicate?

A: The suffix variation reflects internal Cornell Dubilier Electronics manufacturing or packaging designations. The electrical and mechanical specifications remain identical, confirming functional interchangeability.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both parts carry MSL 1 (Unlimited) classification, indicating no moisture-related shelf-life restrictions or special storage requirements.

Q: Can these mica capacitors be substituted with film or ceramic capacitors?

A: No. Mica dielectric material is a defining characteristic of this component class. Substitution with alternative dielectric types (film, ceramic, electrolytic) would alter electrical performance characteristics and is not considered equivalent substitution.

Q: What is the lead spacing tolerance, and does it affect PCB compatibility?

A: Lead spacing is specified as 0.224" (5.70 mm) for both parts. This dimension is fixed and must match PCB through-hole spacing exactly. Both parts are mechanically identical in this regard.
