Key Parameters

Substitute Part Grouping Explanation

Substitution of the QYX1H272KTP is based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Capacitance value: 2700 pF (exact match required)
• Tolerance: ±10% (matching tolerance band)
• Dielectric material: Polyester (functional equivalence)
• Mounting type: Through Hole Radial (mechanical compatibility)
• Voltage rating: Equal to or greater than 50V DC (derating acceptable)

The BFC237051272 satisfies these substitution parameters with a 400V DC rating, which exceeds the original 50V specification and provides design margin. Both components utilize polyester dielectric construction in radial through-hole configuration, ensuring mechanical fit and electrical performance compatibility within the specified tolerance band.

Parameter Comparison

Engineering Selection Recommendations

The BFC237051272 is qualified as a direct substitute for the QYX1H272KTP based on the following factors:

Electrical Compatibility: Both components share identical capacitance (2700 pF) and tolerance (±10%) specifications. The BFC237051272 provides a higher voltage rating (400V DC versus 50V DC), which is acceptable for substitution as it does not reduce the performance envelope of the original design.

Mechanical Compatibility: Both parts utilize radial through-hole mounting with polyester dielectric construction, ensuring PCB layout compatibility and assembly process alignment.

Compliance Status: The BFC237051272 maintains ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the original component. The substitute carries active product status, ensuring long-term availability and supply chain stability.

Temperature Performance: The substitute's extended operating range (-55°C ~ 105°C) exceeds the original specification (-40°C ~ 85°C), providing additional thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the BFC237051272 be used as a direct replacement for the QYX1H272KTP in existing designs?

A: Yes. Both components share identical capacitance and tolerance values with compatible through-hole radial mounting. The higher voltage rating of the substitute does not compromise circuit performance.

Q: What is the significance of the metallized polyester dielectric in the BFC237051272?

A: Metallized polyester construction is a standard variant of polyester film capacitors that maintains electrical performance while offering manufacturing advantages. This does not affect functional substitution for general-purpose applications.

Q: Are there any physical dimension differences that could affect PCB layout?

A: Yes. The QYX1H272KTP measures 0.217" L x 0.118" W with 0.138" lead spacing, while the BFC237051272 measures 0.283" L x 0.098" W with 0.200" lead spacing. PCB footprint verification is required before implementation.

Q: Does the extended temperature range of the substitute provide any design advantages?

A: The BFC237051272 operates from -55°C to 105°C compared to the original -40°C to 85°C range. This extended range may benefit applications with demanding thermal environments, though it is not required for designs originally specified for the QYX1H272KTP.

Q: What compliance certifications apply to the substitute part?

A: The BFC237051272 is ROHS3 compliant and REACH unaffected. It carries AEC-Q200 automotive qualification, indicating suitability for automotive-grade applications.
