Substitute Part Grouping Explanation

Substitution of the BFC230363273 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.027 µF (exact match required)
• Tolerance: ±10% (exact match required)
• DC voltage rating: 630V (minimum requirement; higher ratings acceptable)
• Dielectric type: Polyester, Metallized (exact match required)
• Mounting configuration: Through Hole Radial (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Operating temperature range: -55°C ~ 105°C (minimum requirement)

The BFC237261273 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while offering improved product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The BFC237261273 is the designated manufacturer-recommended substitute for the obsolete BFC230363273. Both components maintain identical electrical specifications for capacitance, tolerance, and DC voltage rating. The substitute offers enhanced AC voltage rating (250V vs. 160V), providing additional design margin in AC applications. Both parts maintain ROHS3 compliance and identical moisture sensitivity classification.

Physical dimensions differ slightly: the substitute exhibits increased width (5.00mm vs. 4.20mm) and height (11.00mm vs. 8.90mm) while maintaining the same lead spacing. PCB layout verification is required to confirm accommodation of the larger footprint in existing designs.

Frequently Asked Questions (FAQ)

Q: Can BFC237261273 be used as a direct replacement for BFC230363273 in all applications?

A: The BFC237261273 matches all critical electrical parameters and lead spacing. Physical dimensions are larger; PCB layout compatibility must be confirmed before implementation.

Q: What is the significance of the different AC voltage ratings (160V vs. 250V)?

A: Both parts maintain the same 630V DC rating. The higher AC rating on the substitute provides additional design margin for AC signal applications but does not affect DC circuit performance.

Q: Are there any compliance or certification differences between these parts?

A: Both components are ROHS3 compliant with identical MSL classification (1 - Unlimited). No compliance differences exist.

Q: Why is the substitute part physically larger?

A: The BFC237261273 belongs to the MKT372 series, which uses different construction geometry than the MKT303 series. The increased dimensions do not affect electrical performance but require PCB layout verification.

Q: Is the substitute part currently available?

A: The BFC237261273 is classified as Active with 975 pieces in stock, ensuring procurement continuity compared to the obsolete BFC230363273.
