Substitute Part Grouping Explanation

Substitute parts for the CMR04F241JPDM are identified based on strict parametric equivalence. The following electrical and mechanical parameters must match identically for a component to function as a direct substitute:

Critical Matching Parameters:

Capacitance value: 240 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: 0.390" L x 0.220" W (9.90mm x 5.60mm)
Maximum seated height: 0.382" (9.70mm)

The substitute part CMR04F241JPDR meets all specified parameters and is therefore classified as a parametric equivalent within the CMR series from Cornell Dubilier Electronics.

Frequently Asked Questions (FAQ)

Q: Can CMR04F241JPDR be used as a direct replacement for CMR04F241JPDM?

A: Yes. The CMR04F241JPDR is a parametric equivalent with identical electrical specifications (240 pF, ±5%, 500 V), dielectric material (mica), operating temperature range (-55°C ~ 150°C), and mechanical configuration (radial through-hole, 0.150" lead spacing, 0.390" L x 0.220" W dimensions). Both components are manufactured by Cornell Dubilier Electronics within the CMR series.

Q: Are there any differences in compliance or certification between these parts?

A: No. Both CMR04F241JPDM and CMR04F241JPDR carry identical compliance certifications: ROHS3 compliant, REACH unaffected, and MSL Level 1 (Unlimited) moisture sensitivity classification.

Q: What is the significance of the lead spacing specification?

A: Lead spacing of 0.150" (3.80mm) is a critical mechanical parameter for through-hole PCB assembly. Both the main part and substitute maintain this identical spacing, ensuring compatibility with existing PCB footprints and assembly equipment without modification.

Q: Does the ±5% tolerance apply to both parts?

A: Yes. Both CMR04F241JPDM and CMR04F241JPDR are specified with ±5% capacitance tolerance, meaning the actual capacitance value will fall within the range of 228 pF to 252 pF at nominal conditions.

Q: What is the maximum operating temperature for these capacitors?

A: Both components are rated for continuous operation up to 150°C and can withstand temperatures as low as -55°C, providing a total operating temperature range of 195°C.
