Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC246728472 is permissible when the alternative component maintains the following critical parameters:

• Capacitance value of 4700 pF with ±10% tolerance
• Voltage rating equal to or greater than 400V DC
• Polyester metallized dielectric construction
• Operating temperature range of -55°C to 105°C minimum
• Through-hole radial mounting configuration
• Lead spacing of 0.394" (10.00mm)
• PC pin termination

The substitute part 160472K630C-F meets all substitution criteria. The elevated DC voltage rating of 630V provides additional safety margin while maintaining identical capacitance, tolerance, dielectric material, temperature range, mounting type, and lead spacing specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the BFC246728472 and 160472K630C-F are active production components with ROHS3 compliance and REACH unaffected status, making either suitable for new designs and existing applications requiring regulatory compliance.

The 160472K630C-F substitute offers a higher DC voltage rating of 630V compared to the 400V rating of the main part, providing increased voltage margin in applications operating near the rated voltage. The substitute component maintains identical capacitance, tolerance, dielectric material, temperature range, and lead spacing specifications required for direct functional replacement.

Physical dimensions show minor variations. The substitute part measures 0.512" L x 0.157" W (13.00mm x 4.00mm) compared to 0.492" L x 0.161" W (12.50mm x 4.10mm) for the main part. The seated height of the substitute is 0.374" (9.50mm), which is lower than the main part's 0.555" (14.10mm). These dimensional differences must be evaluated against available PCB layout space and clearance requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 160472K630C-F be used as a direct replacement for the BFC246728472?

A: Yes, the 160472K630C-F meets all electrical substitution criteria. Both components share identical capacitance (4700 pF), tolerance (±10%), AC voltage rating (220V), dielectric material (polyester metallized), operating temperature range (-55°C to 105°C), mounting type (through hole radial), lead spacing (10.00mm), and termination (PC pins). The substitute has a higher DC voltage rating (630V vs 400V), which is compatible with applications designed for 400V operation.

Q: What are the physical dimension differences between these parts?

A: The main part BFC246728472 measures 12.50mm L x 4.10mm W with a maximum seated height of 14.10mm. The substitute 160472K630C-F measures 13.00mm L x 4.00mm W with a maximum seated height of 9.50mm. The substitute is shorter and slightly longer, requiring verification of available PCB space and component clearance in the target circuit layout.

Q: Are both parts compliant with environmental regulations?

A: Yes, both the BFC246728472 and 160472K630C-F are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the lead spacing specification for these capacitors?

A: Both components have a lead spacing of 0.394" (10.00mm), ensuring compatibility with standard PCB hole patterns designed for this spacing.

Q: Can the substitute part be used in applications where the original part is specified?

A: The 160472K630C-F can be used in applications where the BFC246728472 is specified, provided that the physical dimensions (particularly the reduced seated height of 9.50mm) do not conflict with PCB layout constraints or component clearance requirements in the target circuit.
