Substitute Part Grouping Explanation

Substitute parts for the F863BC104K310Z are identified based on strict parametric equivalence across all electrical and mechanical specifications. The substitution logic requires exact matching of the following critical parameters:

• Capacitance value: 0.1 µF
• Tolerance: ±10%
• Voltage ratings: 630V DC and 310V AC
• Dielectric material: Polypropylene (PP), Metallized
• Operating temperature range: -40°C to 110°C
• Mounting configuration: Through Hole Radial
• Physical dimensions: 18.00mm x 5.00mm with 15.00mm lead spacing
• Termination: PC Pins
• Compliance ratings: AEC-Q200, X2

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. No deviations in any specification are permitted for substitution classification.

Parameter Comparison

Engineering Selection Recommendations

Both the F863BC104K310Z and F863BC104K310ALW0L are active production parts from KEMET's F863 series with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than technical performance differences.

The F863BC104K310ALW0L offers higher inventory availability (2118 pieces in stock) compared to the F863BC104K310Z (880 pieces in stock), making it suitable for high-volume production requirements or extended lead time mitigation.

Both parts maintain full compliance with AEC-Q200 automotive qualification and X2 safety ratings, ROHS3 directives, and REACH regulations. Either part is suitable for direct substitution in automotive EMI and RFI suppression applications without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can F863BC104K310ALW0L be used as a direct replacement for F863BC104K310Z?

A: Yes. Both parts are parametric equivalents with identical capacitance (0.1 µF), voltage ratings (630V DC / 310V AC), tolerance (±10%), dielectric material (polypropylene metallized), operating temperature range (-40°C to 110°C), physical dimensions (18.00mm x 5.00mm), lead spacing (15.00mm), and termination type (PC Pins). Direct substitution is supported without circuit modification.

Q: Are there any differences in automotive compliance between these parts?

A: No. Both parts carry identical AEC-Q200 and X2 ratings, confirming equivalent automotive qualification and safety performance.

Q: What is the significance of the different part number suffixes?

A: The suffix variation (K310Z versus K310ALW0L) represents different manufacturing or packaging codes within KEMET's F863 series. Both suffixes denote the same electrical and mechanical specifications for the 0.1 µF 630V radial film capacitor.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Identical lead spacing (15.00mm), mounting type (through hole radial), and physical dimensions (18.00mm x 5.00mm) ensure mechanical and electrical interchangeability on printed circuit boards without footprint modification.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both F863BC104K310Z and F863BC104K310ALW0L are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for automotive and industrial applications.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supply chain logistics. The F863BC104K310ALW0L currently has higher stock levels (2118 pieces) compared to F863BC104K310Z (880 pieces).
