BQ014D0122K Equivalent & Substitute Parts

Part Overview

The BQ014D0122K is a 1200 pF film capacitor manufactured by KYOCERA AVX, designed for general-purpose applications with a 63V DC voltage rating and polyester metallized dielectric. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance requirements. The radial through-hole configuration and ±10% tolerance establish the baseline parameters for equivalent component selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BQ014D0122K is based on the following critical parameters that must remain constant or exceed the original specification:

• Capacitance Value: 1200 pF (exact match required)
• Tolerance: ±10% (equivalent or tighter tolerance acceptable)
• Dielectric Type: Polyester, Metallized (maintains electrical characteristics)
• Mounting Configuration: Through Hole Radial (physical compatibility)
• Lead Spacing: 0.200" (5.08mm) (PCB layout compatibility)
• Voltage Rating: Minimum 63V DC (equal or higher acceptable)
• Operating Temperature: Minimum -55°C ~ 100°C (equal or wider range acceptable)

The BFC237051122 qualifies as a substitute based on these parameters. While it features a higher voltage rating (400V DC) and extended temperature range (-55°C ~ 105°C), these represent improvements over the original specification and do not compromise compatibility or performance in the intended application.

Parameter Comparison

Engineering Selection Recommendations

The BFC237051122 is a direct functional substitute for the BQ014D0122K based on electrical and mechanical parameter alignment. The substitute part maintains identical capacitance, tolerance, dielectric composition, and physical form factor while providing enhanced voltage rating and extended operating temperature range. The transition from an obsolete component to an active production part ensures long-term supply chain availability and manufacturing continuity.

The BFC237051122 carries AEC-Q200 automotive qualification and ROHS3 compliance, providing additional quality assurance for applications requiring these certifications. The higher voltage rating (400V DC versus 63V DC) presents no compatibility risk in circuits designed for the original 63V specification, as the substitute will operate well within its rated parameters.

Frequently Asked Questions (FAQ)

Q: Can the BFC237051122 be used as a direct replacement for the BQ014D0122K in existing designs?

A: Yes. The BFC237051122 maintains identical capacitance (1200 pF), tolerance (±10%), dielectric material (polyester metallized), mounting type (through hole radial), and lead spacing (0.200"). The higher voltage rating and extended temperature range do not create compatibility issues in circuits originally specified for the BQ014D0122K.

Q: What is the significance of the higher voltage rating on the substitute part?

A: The BFC237051122 is rated for 400V DC compared to the original 63V DC rating. In circuit applications, a component rated for higher voltage than required will operate safely at lower voltages. This characteristic does not affect performance or reliability in the intended application.

Q: Are there physical dimension differences between these parts?

A: The parts are nearly identical in physical dimensions. The BQ014D0122K measures 0.295" L × 0.098" W (7.50mm × 2.50mm), while the BFC237051122 measures 0.283" L × 0.098" W (7.20mm × 2.50mm). Both share the same height (0.256" maximum) and lead spacing (0.200"), ensuring PCB compatibility.

Q: Does the substitute part require any circuit design modifications?

A: No circuit design modifications are required. The substitute part operates within the same electrical parameters as the original component and is suitable for direct board-level replacement.

Q: What compliance certifications does the substitute part carry?

A: The BFC237051122 is ROHS3 compliant and carries AEC-Q200 automotive qualification. These certifications provide additional assurance for applications requiring automotive-grade components or environmental compliance.
