BN154K0104K-- Equivalent & Substitute Parts

Part Overview

The BN154K0104K-- is a 0.1 µF film capacitor manufactured by KYOCERA AVX, rated for 630V DC operation with ±10% tolerance. This radial through-hole component utilizes polyester metallized dielectric technology and is designed for high-pulse and DV/DT applications across an operating temperature range of -55°C to 125°C. The part is currently classified as obsolete, making identification of compatible substitute components essential for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BN154K0104K-- is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.1 µF (exact match required)
• Voltage rating: 630V DC minimum
• Dielectric type: Polyester metallized film
• Mounting configuration: Through-hole radial
• Lead spacing: 15.00mm (0.591")
• Operating temperature range: -55°C to 125°C minimum

The B32522Q8104J000 from EPCOS - TDK Electronics satisfies all substitution criteria. While tolerance differs (±5% versus ±10%), this represents an improvement in precision and does not restrict functional compatibility. The AC voltage rating is lower (200V versus 220V), but this does not affect DC circuit performance. Physical dimensions show minor variations within acceptable mechanical envelope tolerances for radial through-hole mounting.

Engineering Selection Recommendations

The B32522Q8104J000 is the qualified substitute for the obsolete BN154K0104K--. Selection is based on the following engineering factors:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance satisfies modern regulatory requirements, whereas the original part is non-compliant
• Identical capacitance, DC voltage rating, operating temperature range, and mechanical footprint ensure direct functional replacement
• Improved tolerance specification (±5%) provides superior performance margin without introducing compatibility constraints
• Both parts share identical lead spacing and through-hole radial configuration, permitting direct PCB mounting without layout modification

Frequently Asked Questions (FAQ)

Q: Can the B32522Q8104J000 be used as a direct replacement for the BN154K0104K-- on existing PCBs?

A: Yes. Both components feature identical lead spacing (15.00mm), radial through-hole configuration, and PC pin termination. No PCB layout changes are required.

Q: Does the ±5% tolerance of the substitute part affect circuit performance compared to the ±10% original?

A: No. Tighter tolerance represents an improvement and does not restrict compatibility. If the original design functioned within ±10% tolerance, the substitute will perform equivalently or better.

Q: Why is the AC voltage rating lower on the substitute part (200V versus 220V)?

A: AC voltage rating is not a limiting factor for DC circuit applications. Both parts are rated for 630V DC, which is the primary operating parameter. The AC rating difference does not affect DC performance.

Q: What is the significance of ROHS3 compliance on the substitute part?

A: ROHS3 compliance indicates the substitute part meets current environmental and hazardous substance restrictions. The original part is non-compliant with modern standards. For new designs or systems requiring regulatory compliance, the substitute is the appropriate choice.

Q: Are there any physical dimension differences that could affect mechanical fit?

A: Minor dimensional variations exist (length: 17.70mm versus 18.00mm; width: 6.20mm versus 7.00mm; height: 12.20mm versus 12.50mm). These differences remain within acceptable mechanical envelope tolerances for radial through-hole mounting and do not prevent direct substitution.

Q: Is the B32522Q8104J000 available in the same packaging format?

A: The substitute is supplied in bulk packaging, whereas the original part information does not specify packaging format. Both are through-hole radial components suitable for standard PCB assembly processes.
