Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMR05F101FPDP is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 100 pF
• Voltage Rating: 500 V
• Dielectric Material: Mica
• Mounting Type: Through Hole
• Package Type: Radial

Allowable Variation Parameters:

• Tolerance: The main part specifies ±1%; substitute parts with wider tolerances (±5%) remain functionally compatible in general-purpose applications where tolerance stack-up is not critical
• Operating Temperature Range: The main part operates -55°C to 150°C; substitute parts with narrower ranges (-55°C to 125°C) are compatible for applications within the overlapping temperature window
• Lead Spacing: Minor variations (0.224" vs 0.232") are acceptable within standard PCB design tolerances for radial components
• Physical Dimensions: Identical length and width (0.461" L x 0.181" W) ensure PCB footprint compatibility

The CD15FD101JO3 meets all mandatory parameters and operates within the overlapping temperature range, qualifying it as a direct substitute.

Engineering Selection Recommendations

CMR05F101FPDP Selection Criteria:

• Primary choice for applications requiring ±1% tolerance specification
• RoHS3 compliant for regulated markets
• REACH Unaffected status for unrestricted supply chain use
• Operating temperature range extends to 150°C for high-temperature environments
• Recommended for precision circuits where capacitance tolerance is a design constraint

CD15FD101JO3 Selection Criteria:

• Suitable for general-purpose applications where ±5% tolerance is acceptable
• Higher inventory availability (1398 pcs vs 1114 pcs)
• Operating temperature range limited to 125°C; verify application maximum operating temperature does not exceed this threshold
• RoHS non-compliant status requires evaluation against target market regulatory requirements
• REACH Affected status may require additional supply chain documentation

Both parts share identical capacitance, voltage rating, dielectric material, and radial through-hole package configuration, ensuring functional interchangeability within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can CD15FD101JO3 replace CMR05F101FPDP in all applications?

A: CD15FD101JO3 is functionally compatible for applications where the operating temperature does not exceed 125°C and ±5% capacitance tolerance is acceptable. Applications requiring ±1% tolerance or operation above 125°C require the CMR05F101FPDP.

Q: What is the impact of ±5% tolerance versus ±1% tolerance?

A: The ±5% tolerance on CD15FD101JO3 results in a capacitance range of 95 pF to 105 pF, compared to 99 pF to 101 pF for the ±1% CMR05F101FPDP. Applications with tight capacitance requirements or frequency-dependent circuits should use the tighter tolerance part.

Q: Are the lead spacings compatible with the same PCB footprint?

A: Lead spacing differs by 0.008" (0.20mm). Both parts fit standard radial capacitor footprints with 0.25" (6.35mm) pitch spacing. Verify PCB design tolerances accommodate this minor variation.

Q: What compliance differences exist between these parts?

A: CMR05F101FPDP is RoHS3 compliant and REACH Unaffected. CD15FD101JO3 is RoHS non-compliant and REACH Affected. Applications destined for regulated markets (EU, California) require compliance verification before substitution.

Q: Can these parts be used interchangeably in high-temperature circuits?

A: No. CMR05F101FPDP operates to 150°C; CD15FD101JO3 operates to 125°C maximum. High-temperature applications above 125°C require the CMR05F101FPDP.

Q: Are physical dimensions identical?

A: Yes. Both parts share identical length (0.461"), width (0.181"), and seated height (0.358"), ensuring PCB footprint compatibility.
