Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC246921224 is based on electrical and mechanical parameter matching within the Vishay film capacitor portfolio. The critical parameters determining substitutability are:

• Capacitance value: 0.22 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 100V DC minimum (equal or higher 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 to 105°C (equal or wider range acceptable)

The BFC246751224 qualifies as a direct substitute based on matching all critical electrical parameters and mechanical footprint specifications. Both components share identical capacitance, tolerance, voltage ratings, dielectric material, and lead spacing. The substitute part is from the MKT467 series and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The BFC246751224 is a direct electrical equivalent to the BFC246921224 with full parameter compatibility across all critical specifications. Both components maintain ROHS3 compliance and identical electrical performance characteristics. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete main part number.

The primary design consideration is the increased seated height of the substitute part: 0.575" (14.60mm) versus 0.453" (11.50mm) for the original. This 0.122" (3.10mm) height difference must be evaluated against available PCB clearance in the target application. The identical lead spacing and radial configuration ensure direct footprint compatibility on standard through-hole layouts.

Frequently Asked Questions (FAQ)

Q: Can BFC246751224 be used as a direct replacement for BFC246921224?

A: Yes. Both parts share identical electrical specifications: 0.22 µF capacitance, ±10% tolerance, 100V DC rating, polyester metallized dielectric, and 10.00mm lead spacing. The substitute maintains the same operating temperature range and RoHS3 compliance status.

Q: What is the difference between these two part numbers?

A: The parts belong to different Vishay series (MKT469 versus MKT467) and differ in seated height. BFC246751224 measures 0.575" (14.60mm) maximum height compared to 0.453" (11.50mm) for BFC246921224. The substitute part is currently active in production, while the original is obsolete.

Q: Will the taller height of BFC246751224 cause PCB assembly issues?

A: Height compatibility depends on available vertical clearance in the target application. The 0.122" (3.10mm) additional height must be verified against component placement constraints, conformal coating requirements, and enclosure dimensions. Lead spacing and footprint remain identical.

Q: Are both parts RoHS compliant?

A: Yes. Both BFC246921224 and BFC246751224 are ROHS3 compliant. The substitute part is REACH unaffected.

Q: What is the inventory status of these parts?

A: BFC246921224 has 953 pieces in stock as new original inventory. BFC246751224 has 1092 pieces in stock as new original inventory in bulk packaging.
