Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC230354154 is based on strict electrical and mechanical parameter alignment. The substitute part BFC237354154 maintains compatibility through the following criteria:

• Identical capacitance value: 0.15 µF
• Identical capacitance tolerance: ±5%
• Identical DC voltage rating: 400V
• Identical dielectric material: Polyester, Metallized
• Identical operating temperature range: -55°C ~ 105°C
• Identical mounting type: Through Hole
• Identical package type: Radial
• Identical termination: PC Pins
• Identical RoHS compliance: ROHS3 Compliant

The substitute part operates at a higher AC voltage rating (220V versus 100V) and belongs to a different series (MKT373 versus MKT303), but these differences do not restrict substitution when DC voltage and capacitance specifications are the primary design constraints.

Parameter Comparison

Engineering Selection Recommendations

The BFC237354154 is an active product substitute for the obsolete BFC230354154. Both components maintain identical electrical specifications for capacitance, tolerance, DC voltage rating, and operating temperature range. Both are ROHS3 compliant with MSL rating of 1, ensuring equivalent environmental and regulatory compliance.

Physical dimensions differ between the two parts. The substitute BFC237354154 is larger in length (17.50mm versus 12.50mm), width (5.00mm versus 4.80mm), height (11.00mm versus 9.50mm), and lead spacing (15.00mm versus 10.00mm). PCB layout modifications may be required to accommodate these dimensional changes. The substitute part's higher AC voltage rating (220V versus 100V) provides additional margin in AC applications without affecting DC circuit performance.

Frequently Asked Questions (FAQ)

Q: Can BFC237354154 directly replace BFC230354154 in all applications?

A: Electrical substitution is valid when DC voltage and capacitance specifications are the primary design constraints. Physical dimensions differ; PCB layout verification is necessary to confirm lead spacing and component height compatibility with existing board designs.

Q: What is the significance of the different AC voltage ratings?

A: The substitute part's 220V AC rating versus the original 100V AC rating does not restrict substitution in DC-biased or general-purpose applications. The higher AC rating provides additional safety margin in AC circuits without affecting DC performance.

Q: Are both parts RoHS compliant?

A: Yes. Both BFC230354154 and BFC237354154 are ROHS3 compliant with identical MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance.

Q: Why is the original part obsolete?

A: The BFC230354154 belongs to the MKT303 series, which has been superseded by the MKT373 series. The BFC237354154 represents the active equivalent within Vishay's current product portfolio.

Q: What are the lead spacing differences?

A: The original BFC230354154 has 10.00mm lead spacing, while the substitute BFC237354154 has 15.00mm lead spacing. PCB hole pattern verification is required before implementation.
