Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BFC237323105 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 1 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 100V DC minimum (equal or higher acceptable)
• Dielectric material: Polyester, Metallized (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.591" (15.00mm) (exact match required)
• Termination style: PC Pins (exact match required)
• Operating temperature range: -55°C to 105°C (equal or wider range acceptable)
• Compliance certifications: ROHS3 Compliant, REACH Unaffected (maintained)

The BFC237321105 qualifies as a direct substitute based on full alignment with these parameters. Physical dimension variations (length and height) remain within acceptable tolerances for PCB layout compatibility while maintaining all electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the BFC237323105 and BFC237321105 are active production components manufactured by Vishay Beyschlag/Draloric/BC Components within the MKT373 series. Both parts maintain full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.

Selection between these parts should be based on inventory availability and lead time requirements. The BFC237321105 currently maintains higher stock levels (2532 units versus 1373 units), which may provide supply chain advantages. Both parts are electrically and mechanically interchangeable for applications requiring a 1 µF, 100V DC polyester film capacitor with radial through-hole mounting.

Frequently Asked Questions (FAQ)

Q: Can the BFC237321105 be used as a direct replacement for the BFC237323105?

A: Yes. Both parts share identical electrical specifications (1 µF capacitance, ±10% tolerance, 100V DC rating, 63V AC rating), dielectric material (polyester metallized), mounting configuration (through-hole radial), lead spacing (15.00mm), and operating temperature range (-55°C to 105°C). Physical dimensions vary slightly in length and height, but both maintain the same lead spacing and footprint compatibility for standard PCB layouts.

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

A: No. Both parts carry identical compliance certifications: ROHS3 compliant, REACH unaffected, MSL rating of 1 (unlimited), and the same ECCN and HTSUS classifications.

Q: What are the physical dimension differences?

A: The BFC237323105 measures 0.689" L × 0.197" W with a maximum seated height of 0.433". The BFC237321105 measures 0.689" L × 0.236" W with a maximum seated height of 0.472". The length remains constant; width and height increase slightly in the substitute part. Lead spacing remains 0.591" (15.00mm) for both, ensuring PCB hole compatibility.

Q: Should physical dimension differences affect component selection?

A: Physical dimension variations should be evaluated within the context of available PCB space and component placement constraints. The identical lead spacing ensures that both parts fit standard 15.00mm pitch holes. Verify that the increased width and height of the BFC237321105 do not conflict with adjacent components or board layout requirements.

Q: Are both parts suitable for the same application categories?

A: Yes. Both parts are rated for general-purpose applications and share identical electrical performance characteristics, operating temperature ranges, and long-life feature designation.
