Key Parameters

Substitute Part Grouping Explanation

Substitution of the MKP1846415105 is determined by the following critical parameters:

• Capacitance Value: Must be 0.15 µF (exact match required)
• Voltage Rating - DC: Must be equal to or greater than 1000V
• Dielectric Material: Must be Polypropylene (PP), Metallized
• Mounting Type: Must be Through Hole, Radial configuration
• Lead Spacing: Must be 1.083" (27.50mm) to ensure PCB compatibility
• Termination: Must use PC Pins

The substitute part BFC238350154 meets all these criteria while offering improved electrical performance through higher voltage rating and tighter tolerance specifications.

Engineering Selection Recommendations

The BFC238350154 is the qualified substitute for the obsolete MKP1846415105. Selection is based on the following engineering criteria:

• Electrical Compatibility: The substitute maintains the same 0.15 µF capacitance value and polypropylene dielectric material. The DC voltage rating of 1600V exceeds the original 1000V requirement, providing additional design margin.
• Physical Compatibility: Lead spacing, mounting type, and termination are identical, ensuring direct PCB footprint compatibility without layout modifications.
• Regulatory Compliance: Both parts are ROHS3 compliant, maintaining environmental and regulatory standards.
• Availability: The substitute is in active production status with 2228 pieces in stock, compared to the obsolete main part with limited remaining inventory.
• Performance Enhancement: The substitute offers ±5% tolerance versus ±10%, and an extended operating temperature range to 105°C.

The AC voltage rating of the substitute (550V) is lower than the main part (600V). This parameter difference must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can BFC238350154 be used as a direct replacement for MKP1846415105?

A: Yes, for applications where the DC voltage requirement is 1000V or less. The substitute provides identical capacitance, dielectric material, mounting configuration, and lead spacing. PCB layout modifications are not required.

Q: What is the significance of the voltage rating difference?

A: The substitute BFC238350154 has a higher DC voltage rating (1600V vs. 1000V), which is advantageous for design margin. However, its AC voltage rating (550V) is lower than the original part (600V). Applications requiring AC voltage operation above 550V must use the original part or identify alternative substitutes.

Q: Does the tolerance difference affect circuit performance?

A: The substitute offers tighter tolerance (±5% vs. ±10%), which reduces capacitance variation across the production range. This generally improves circuit performance and consistency, particularly in precision filtering and timing applications.

Q: Are there any thermal considerations?

A: The substitute operates to 105°C versus 100°C for the original part, providing a 5°C extended operating range. Both parts maintain the same -55°C lower limit. Thermal performance should be evaluated based on specific application conditions.

Q: Is the substitute available in the same packaging?

A: Both parts use radial through-hole configuration with identical lead spacing (27.50mm). The substitute is supplied in bulk packaging, while the original part information does not specify packaging type. Verify packaging requirements for your procurement process.
