Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for the WMF6S22K are determined by equivalence across the following critical electrical and mechanical parameters:

• Capacitance Value: 0.022 µF (exact match required)
• Voltage Rating (DC): 630V (equal or higher acceptable)
• Tolerance: ±10%
• Dielectric Material: Polyester
• Mounting Type: Through Hole Axial
• Physical Dimensions: 0.335" Dia x 0.937" L (8.50mm x 23.80mm)
• Termination: PC Pins

Parts meeting all criteria above are considered direct substitutes. The WMF6S22K-F satisfies all equivalence parameters while offering improved product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The WMF6S22K-F is the direct substitute for the obsolete WMF6S22K. Both components are identical in electrical performance and physical form factor. The WMF6S22K-F provides the additional advantage of active product status, ensuring ongoing availability and supply chain reliability. Furthermore, the WMF6S22K-F meets ROHS3 compliance requirements, whereas the original WMF6S22K does not. Selection of the WMF6S22K-F is appropriate for new designs and replacement applications requiring modern regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can WMF6S22K-F replace WMF6S22K in existing designs? A: Yes. Both components share identical electrical specifications (0.022 µF, ±10%, 630V DC) and physical dimensions (0.335" Dia x 0.937" L). They are mechanically and electrically interchangeable.

Q: What is the primary difference between these parts? A: The WMF6S22K-F is the current production equivalent of the obsolete WMF6S22K. The primary differences are product status (Active vs. Obsolete) and regulatory compliance (ROHS3 Compliant vs. non-compliant).

Q: Are there packaging differences? A: The WMF6S22K is supplied in standard packaging, while WMF6S22K-F is supplied in bulk packaging. Both maintain identical component specifications and form factors.

Q: Can this capacitor be used in high-temperature applications? A: Yes. Both parts operate across the temperature range -55°C ~ 125°C, supporting applications within this thermal specification.

Q: What certifications does the substitute part hold? A: The WMF6S22K-F is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
