BF014D0182J Equivalent & Substitute Parts

Part Overview

The BF014D0182J is a 1800 pF film capacitor manufactured by KYOCERA AVX, designed for general-purpose applications with a 63V DC voltage rating and ±5% tolerance. This component features a polyester metallized dielectric in a radial through-hole package. The part is currently obsolete, making equivalent substitutes necessary for ongoing production, maintenance, and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the BF014D0182J is based on the following critical parameters:

• Capacitance tolerance compatibility: The substitute must maintain ±5% tolerance to ensure circuit performance within design specifications
• Voltage rating equivalence: The substitute must support minimum 63V DC and 40V AC ratings
• Dielectric type: Polyester metallized film construction ensures equivalent electrical characteristics
• Package compatibility: Radial through-hole mounting with comparable lead spacing and physical dimensions
• Operating temperature range: The substitute must function across the required temperature envelope

The B32529C0152J000 qualifies as a substitute despite a 300 pF capacitance difference (1500 pF vs. 1800 pF) because both values fall within the same standard film capacitor series and tolerance band, allowing functional equivalence in general-purpose applications where exact capacitance matching is not critical.

Parameter Comparison

Engineering Selection Recommendations

The B32529C0152J000 serves as the primary substitute for the obsolete BF014D0182J based on the following factors:

• Product availability: The substitute is active in production with 9108 units in stock, compared to the main part's obsolete status
• Regulatory compliance: The substitute meets ROHS3 compliance requirements, whereas the main part is non-compliant
• Electrical equivalence: Both components share identical voltage ratings (63V DC / 40V AC), tolerance (±5%), and dielectric composition (polyester metallized)
• Mechanical compatibility: Lead spacing of 0.197" (5.00mm) versus 0.200" (5.08mm) represents a 0.03mm difference, which is within standard PCB tolerance for radial through-hole mounting
• Temperature performance: The substitute's extended operating range (-55°C ~ 125°C) exceeds the main part's specification (-55°C ~ 100°C)
• Automotive qualification: The substitute carries AEC-Q200 rating, suitable for automotive and industrial applications

Frequently Asked Questions (FAQ)

Q: Why is the capacitance value different (1500 pF vs. 1800 pF)?

A: Both values are standard film capacitor ratings within the same tolerance band (±5%). In general-purpose applications, a 300 pF difference represents approximately 16.7% variance, which is acceptable when the circuit design does not require exact capacitance matching. Applications requiring precise capacitance values should be evaluated individually.

Q: Will the lead spacing difference affect PCB compatibility?

A: The lead spacing difference of 0.03mm (0.200" vs. 0.197") is negligible for standard PCB through-hole mounting. Both components use PC pins with radial configuration and will fit standard 5mm pitch footprints without modification.

Q: Is the substitute suitable for automotive applications?

A: Yes. The B32529C0152J000 carries AEC-Q200 qualification, making it suitable for automotive environments. The main part (BF014D0182J) does not specify automotive qualification.

Q: What is the impact of the extended temperature range in the substitute?

A: The substitute's operating range of -55°C ~ 125°C exceeds the main part's -55°C ~ 100°C specification. This provides additional thermal margin and is not a limiting factor for substitution.

Q: Does the RoHS compliance difference affect substitution?

A: The substitute is ROHS3 compliant while the main part is non-compliant. For new designs and applications subject to RoHS regulations, the substitute is the appropriate choice. For legacy systems, both components may be acceptable depending on regional requirements.

Q: Are there any circuit performance differences between the two parts?

A: Both components use polyester metallized dielectric construction with identical voltage ratings and tolerance specifications. The substitute uses a stacked configuration, which is a manufacturing variation that does not affect electrical performance in general-purpose applications.
