Substitute Part Grouping Explanation

Substitution eligibility for the F863RL475K310ALW0L is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 4.7 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Ratings: 630V DC and 310V AC (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -40°C to 110°C (exact match required)
• Mounting Configuration: Through Hole, Radial package with PC Pins termination (exact match required)
• Lead Spacing: 1.476" (37.50mm) (exact match required)
• Compliance Standards: AEC-Q200, X2 ratings (exact match required)

The substitute part F863RL475K310Z meets all these criteria, differing only in the final suffix designation (Z versus ALW0L), which represents a variation within the same F863RL base product number series. Both parts maintain identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both F863RL475K310ALW0L and F863RL475K310Z are Active products from KEMET's F863 series and are suitable for direct substitution in applications requiring 4.7 µF, 630V DC film capacitors with automotive-grade compliance. Selection between these parts should be based on inventory availability and procurement lead times, as all electrical, mechanical, and compliance parameters are identical.

Both parts carry AEC-Q200 qualification, confirming suitability for automotive applications. ROHS3 compliance and REACH Unaffected status ensure regulatory compatibility across global markets. The radial through-hole configuration with 37.50mm lead spacing permits direct PCB mounting without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can F863RL475K310Z be used as a direct replacement for F863RL475K310ALW0L?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. The suffix variation (Z versus ALW0L) represents a designation difference within the same base product series (F863RL) and does not affect functional performance or compatibility.

Q: Are there any differences in the physical dimensions between these two parts?

A: No. Both parts share identical dimensions: 1.634" L x 0.748" W (41.50mm x 19.00mm) with a maximum seated height of 1.264" (32.10mm) and lead spacing of 1.476" (37.50mm). PCB layout and mounting hole spacing remain unchanged.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both F863RL475K310ALW0L and F863RL475K310Z carry AEC-Q200 certification and X2 ratings, confirming compliance with automotive reliability and safety requirements.

Q: What is the operating temperature range for these capacitors?

A: Both parts operate across -40°C to 110°C, suitable for automotive underhood and industrial applications requiring extended temperature performance.

Q: Are these parts RoHS compliant?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What dielectric material is used in these capacitors?

A: Both parts use Polypropylene (PP) with metallized construction, providing stable capacitance across the operating temperature range and excellent performance in EMI/RFI suppression applications.
