Substitute Part Grouping Explanation

Substitution logic for the WMF6S15K is based on strict electrical and mechanical parameter matching:

Key Substitution Parameters:

• Capacitance value: 0.015 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 630V (exact match required)
• Dielectric Material: Polyester (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Axial (exact match required)
• Size / Dimension: 0.295" Dia x 0.937" L (exact match required)
• Termination: PC Pins (exact match required)

The WMF6S15K-F is classified as a direct manufacturer substitute, maintaining identical electrical specifications and physical dimensions while representing the current active product line designation from Cornell Dubilier Electronics.

Engineering Selection Recommendations

The WMF6S15K-F is the direct successor to the WMF6S15K and represents the recommended substitution choice. The substitute part maintains full electrical and mechanical equivalence while offering the following advantages:

• Product Status: The WMF6S15K-F is classified as active, ensuring continued availability and manufacturing support from Cornell Dubilier Electronics.
• Regulatory Compliance: The WMF6S15K-F achieves RoHS3 compliance, whereas the original WMF6S15K is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations.
• REACH Status: Both parts maintain REACH Unaffected designation, indicating no regulatory restrictions on use.

Selection of the WMF6S15K-F eliminates obsolescence risk and provides access to active product line manufacturing.

Frequently Asked Questions (FAQ)

Q: Are the WMF6S15K and WMF6S15K-F electrically identical?

A: Yes. Both components specify identical capacitance (0.015 µF), tolerance (±10%), voltage rating (630V DC), dielectric material (polyester), and operating temperature range (-55°C to 125°C).

Q: Can the WMF6S15K-F be used as a drop-in replacement for the WMF6S15K?

A: Yes. The WMF6S15K-F shares identical physical dimensions (0.295" Dia x 0.937" L), axial package configuration, through-hole mounting, and PC pin termination, making it a direct drop-in replacement for printed circuit board applications.

Q: What is the significance of the RoHS compliance difference?

A: The WMF6S15K is RoHS non-compliant, while the WMF6S15K-F is RoHS3 compliant. For applications manufactured for markets requiring RoHS compliance, the WMF6S15K-F is the required selection.

Q: Are there inventory considerations for substitution?

A: Current inventory shows 924 pieces of the WMF6S15K (obsolete) and 1119 pieces of the WMF6S15K-F (active). The active status of the WMF6S15K-F ensures ongoing procurement capability.

Q: Do both parts share the same ECCN and HTSUS classifications?

A: Yes. Both the WMF6S15K and WMF6S15K-F are classified under ECCN EAR99 and HTSUS code 8532.25.0060, maintaining identical trade classification.
